Aims. The aim of this study was to report the outcome following primary fixation or a staged protocol for type C fractures of the tibial plafond. Patients and Methods. We studied all patients who sustained a complex intra-articular fracture (AO type C) of the distal tibia over an 11-year period. The primary short-term outcome was infection. The primary long-term outcome was the Foot and Ankle Outcome Score (FAOS). Results. There were 102 type C pilon fractures in 99 patients, whose mean age was 42 years (16 to 86) and 77 were male. Primary open reduction internal fixation (ORIF) was performed in 73 patients (71.6%), whilst 20 (19.6%) underwent primary external fixation with delayed ORIF. There were 18 wound infections (17.6%). A total of nine (8.8%) were deep and nine were superficial. Infection was associated with comorbidities (p = 0.008), open fractures (p = 0.008) and primary external fixation with delayed ORIF (p = 0.023). At a mean of six years (0.3 to 13; n = 53) after the injury, the mean FAOS was 76.2 (0 to 100) and 72% of patients were satisfied. Conclusion. This is currently the largest series reporting the outcome following fixation of complex AO type C tibial pilon fractures. Despite the severity of these injuries, we have demonstrated that a satisfactory outcome can be achieved in the appropriate patients using primary ORIF.

Objectives. Pilon fractures represent one of the most surgically challenging fractures in orthopaedics. Different techniques exist for their management, with open reduction and internal fixation (ORIF) and External fixation (Ex-Fix) the most widely used. Whilst there is a plethora of data regarding these strategies for Pilon fractures as a whole, very limited data exists solely on the management of open Pilon fractures. This study aimed to elucidate how surgical management options can influence postoperative complications, and if this can influence future management protocols. Materials and methods. We conducted a search in PubMed, EMBASE and CENTRAL for postoperative complications and functional outcomes in open pilon fractures in those treated with Ex-Fix vs ORIF (PROSPERO-CRD42020184213). The postoperative complications measured included non-union, mal-union, delayed union, bone grafting, amputation, osteoarthritis, deep infection and superficial infection. Functional outcomes in the form of the AOFAS score was also measured where possible. We were able to carry out a meta-analysis for both deep infections and non-unions. Results. The search yielded 309 results and a total of 18 studies consisting of 484 patients were included. All fractures included were open, and consisted of 64 Gustilo-Anderson Type I, 148 Type II, 103 Type IIIa, 90 Type IIIb and 9 Type IIIc. 60 Type III fractures could not be further separated and 12 were ungraded. Both ORIF and Ex-Fix were found to have statistically similar AOFAS scores (p=0.682). For all included studies, the Ex-Fix group had significantly higher rates of superficial infections (p=0.001), non-unions (p=0.001), osteoarthritis (p=0.001) and bone grafting (p=0.001). The meta-analysis found no significant difference in non-union (pooled OR=0.25, 95% CI: 0.03 to 2.24, p = 0.44) or deep infection rates (pooled OR=1.35, 95% CI: 0.11 to 16.69, p = 0.12) between the ORIF and Ex-fix groups. Conclusion. Based on our study, while Ex-Fix and ORIF have similar functional outcomes, Ex-Fix appears to have a significantly higher risk of postoperative complications which must be considered by surgeons when choosing surgical management options. Further research, ideally in a randomised control trial format, is required to definitively demonstrate ORIF superiority in the management of open pilon fractures

In a series of 126 consecutive pilon fractures, we have described anatomically explicable fragments. Fracture lines describing these fragments have revealed ten types of pilon fracture which belong to two families, sagittal and coronal. The type of fracture is dictated by the energy of injury, the direction of the force of injury and the age of the patient

Open reduction and internal fixation of high-energy pilon fractures are often associated with serious complications. Various methods have been used to treat these injuries, with variable results. A total of 17 consecutive patients with pilon fractures of AO/OTA type 43-B3 (n = 1), type C2 (n = 12) and type C3 (n = 4) were treated by indirect reduction by capsuloligamentotaxis and stabilisation using an ankle-spanning Ilizarov fixator. The calcaneal ring was removed at a mean of 3.7 weeks (3 to 6). A total of 16 patients were available for follow-up at a mean of 29 months (23 to 43). The mean time to healing was 15.8 weeks (13 to 23). Nine patients had pin-track infections but none had deep infection or osteomyelitis. Four patients (25%) had malunion. Fair, good or excellent ankle scores were found in 14 patients. External fixation with a ring fixator achieves stable reduction of the fractured fragments without additional trauma to soft tissues. With minimum complications and good healing results, the Ilizarov apparatus is particularly useful for high-energy pilon fractures

Aims. A pilon fracture is a severe ankle joint injury caused by high-energy trauma, typically affecting men of working age. Although relatively uncommon (5% to 7% of all tibial fractures), this injury causes among the worst functional and health outcomes of any skeletal injury, with a high risk of serious complications and long-term disability, and with devastating consequences on patients’ quality of life and financial prospects. Robust evidence to guide treatment is currently lacking. This study aims to evaluate the clinical and cost-effectiveness of two surgical interventions that are most commonly used to treat pilon fractures. Methods. A randomized controlled trial (RCT) of 334 adult patients diagnosed with a closed type C pilon fracture will be conducted. Internal locking plate fixation will be compared with external frame fixation. The primary outcome and endpoint will be the Disability Rating Index (a patient self-reported assessment of physical disability) at 12 months. This will also be measured at baseline, three, six, and 24 months after randomization. Secondary outcomes include the Olerud and Molander Ankle Score (OMAS), the five-level EuroQol five-dimenison score (EQ-5D-5L), complications (including bone healing), resource use, work impact, and patient treatment preference. The acceptability of the treatments and study design to patients and health care professionals will be explored through qualitative methods. Discussion. The two treatments being compared are the most commonly used for this injury, however there is uncertainty over which is most clinically and cost-effective. The Articular Pilon Fracture (ACTIVE) Trial is a sufficiently powered and rigorously designed study to inform clinical decisions for the treatment of adults with this injury.

Tibial Pilon fractures pose a difficult management problem. For logical fracture treatment, precise understanding of the 3-D anatomy is essential. We have studied a consecutive series of 126 pilon fractures. Digitised X-rays and CT scans were analysed using a CAD programme. We have defined six main fragments at the articular surface, their relative frequency and their proportion: Anterior (A) present in 89%, 28% of area. Posterior (P) present in 89%, 40% of area. Medial (M) present in 74%, 29% of area. Anterolateral (AL) present in 34%, 8% of area. Posterolateral (PL) present in 21%, 9% of area. Die-punch (DP) present in 43%, 4% of area. The primary fracture line varied in orientation from coronal (93%) to sagittal (7%), in contrast to the classic description. Within those cases where the primary fracture line was coronal we found hitherto undescribed variations in the articular pattern, there being ‘T’, ‘V’, ‘Y’ and pure split fractures with respect to the medial fragment. Fractures which displace into varus show a “T” configuration, those in valgus a “Y” or “V” configuration, (p < 0.001). Fractures with no coronal mal-alignment produce a talo-fibular joint disruption. Once recognised these different articular patterns require individual techniques for anatomic reduction and fixation

Background: Tibial Pilon fractures pose a difþcult management problem. For logical fracture treatment, precise understanding of the 3-D anatomy is essential. Methods: We have studied a consecutive series of 126 pilon fractures. Digitised Xrays and CT scans were analysed using a CAD programme. Results: We have deþned 6 main fragments, at the articular surface. The primary fracture line varied in orientation from coronal (93%) to sagittal (7%), in contrast to the classic description. Observation of the articular fracture patterns revealed ñTñ, ñVñ, ñYñ and pure split fractures with respect to the medial fragment. Fractures, which displace into varus, show a ÒTÒ conþguration, those in valgus a ÒYÒ or ÒVÒ conþguration, (p < 0.001). Fractures with no coronal mal-alignment produce a talo-þbular joint disruption. These different articular patterns require individual techniques for anatomic reduction and þxation

Introduction: Tibial pilon fractures are complex and difficult to manage. Results with extensile approaches, rigid internal fixation and bone grafting remain poor. Percutaneous treatment does not allow anatomic restoration. Current classifications are not helpful. Understanding the anatomy and behaviour of the fracture would allow development of logical algorithms for treatment. Method: We have analysed plain radiographs and CT scans in a consecutive series of 126 pilon fractures and have defined the fracture anatomy and developed a new classification. Results: There are six constant articular fragments: anterior, anterolateral (insertion of AITFL), medial, posterior, posterolateral (insertion of PITFL) and die-punch. Two main fracture families exist depending on the articular fracture pattern. T-type and V/Y-type fractures. A lateral disruption type fracture represents a further important group. An evolution of fracture is evident within the groups. T-type fractures tend to occur in varus and result from higher energy injuries in younger patients. V/Y-type fractures tend to occur in valgus and result from lower energy injuries in older patients. Conclusions: We have defined distinct articular fragments, allowing development of safe direct surgical exposures. Stabilisation of the tibial fracture with fine-wire fixators or plates may be employed. The Pathoanatomy could be used in optimal design of such plates. Defining the fracture types gives us a useful and reproducible classification of injury

Optimal treatment of articular fractures is open anatomic reduction and rigid internal fixation. In pilon fractures, this has been associated with unacceptable complication rates. The cutaneous blood supply of the anterior aspect of the distal tibia is from short direct radial vessels which themselves arise from arteries closely adherent to the deep fascia. On the anteromedial aspect of the leg the deep fascia is fused with the periosteum. We hypothesise that shearing associated with displaced fractures divide these short radial vessels, rendering the skin critically ischaemic. Standard extensile approaches lead to further devitalisation and wound breakdown. It follows that a direct approach onto the fracture line should do minimal extra damage to the blood supply. Of 97 pilon fractures, 53 have required an open reduction. Median age 43, 39 male. Mechanism of Injury: fall-41, RTA-10, other-two. 19% open (60% IIIB). Time to surgery nine days. A longitudinal incision with full thickness flaps is based directly over the fracture, not necessarily following internervous planes. Anatomic reduction was achieved in all cases. There was only one complication of wound breakdown (2%). This technique affords a safe and reliable approach to the fractured articular surface. Lack of wound breakdown may rely on the use of fine-wire circular frame external fixators for stabilisation of the proximal fracture. Whether this approach will allow plate fixation, remains to be seen

Introduction: Classification systems are useful in research and clinical practise as it provides a common mode of communication and evaluation. Tibial pilon injuries are a complex group of fractures, whose classification and radiological assessment in clinical practise remains undetermined. Methods: 50 CT scans and radiographs of tibial pilon fractures were evaluated independently by 6 orthopaedic surgeons, comprising 3 consultants, 2 registrars and 1 research fellow. Fractures were classified according to ruedi allgower, AO, Topliss et al. Each surgeon was given a period of 48 hours to review copy of the original article as well as written and diagrammatic representations. Assessment was done on two occasions, 4 weeks apart. The kappa coefficient of agreement was calculated with SPSS to determine interobserver reliability and intraobserver reproducibility of the classification systems. The evaluator was blinded as to treatment and functional outcome. Each evaluator was also asked to decide upon the fracture management based on the classification types and was compared with the actual management. Result: The interobserver agreement for ruedi allgower, Ao and Topliss et al., was fair, moderate and poor respectively. The intraobserver agreement for ruedi allgower, AO and Topliss et al., classifications was moderate at best. There was poor agreement amongst observers regarding definite management plan based on these classification systems. Discussion: The interobserver agreement was directly proportional to the familiarity and inversely proportional to the specificity of the classification system. The intraobserver agreement improved with experience. CT scan helped in delineating the fracture segments accurately but did not significantly affect inter or intraob-server agreement. Conclusion: Existing classification systems help in understanding the pathoanatomy of osseous part of tibial pilon fracture complex. However, Soft tissue injury forms an integral part of this complex. Without inclusion of soft tissue injury, these classification systems have limited role in definitive management

Aims. Complex joint fractures of the lower extremity are often accompanied by soft-tissue swelling and are associated with prolonged hospitalization and soft-tissue complications. The aim of the study was to evaluate the effect of vascular impulse technology (VIT) on soft-tissue conditioning in comparison with conventional elevation. Methods. A total of 100 patients were included in this prospective, randomized, controlled monocentre study allocated to the three subgroups of dislocated ankle fracture (n = 40), pilon fracture (n = 20), and intra-articular calcaneal fracture (n = 40). Patients were randomized to the two study groups in a 1:1 ratio. The effectiveness of VIT (intervention) compared with elevation (control) was analyzed separately for the whole study population and for the three subgroups. The primary endpoint was the time from admission until operability (in days). Results. The mean length of time until operability was 8.2 days (SD 3.0) in the intervention group and 10.2 days (SD 3.7) in the control group across all three fractures groups combined (p = 0.004). An analysis of the subgroups revealed that a significant reduction in the time to operability was achieved in two of the three: with 8.6 days (SD 2.2) versus 10.6 days (SD 3.6) in ankle fractures (p = 0.043), 9.8 days (SD 4.1) versus 12.5 days (SD 5.1) in pilon fractures (p = 0.205), and 7.0 days (SD 2.6) versus 8.4 days (SD 1.5) in calcaneal fractures (p = 0.043). A lower length of stay (p = 0.007), a reduction in pain (p. preop. = 0.05; p. discharge. < 0.001) and need for narcotics (p. preop. = 0.064; p. postop. = 0.072), an increased reduction in swelling (p < 0.001), and a lower revision rate (p = 0.044) could also be seen, and a trend towards fewer complications (p = 0.216) became apparent. Conclusion. Compared with elevation, VIT results in a significant reduction in the time to achieve operability in complex joint fractures of the lower limb.

Objective and Purpose: Pilon fractures are complex fractures of the tibial articular surface usually associated with high energy trauma and major soft tissue injury. We investigated the effectiveness of Ilizarov external fixator in such cases. At our hospital, we obtain excellent results performing reconstruction using vascularised fibular grafts for the infectious non-union. Methods and Materials: We examined 21 cases treated with the Ilizarov apparatus for the fresh pilon fracture from 1999. There were 13 males and 8 females, with an average of 44 years. The AO classification was A2 type in 2 cases, B1 in 4, C1 in 3, C2 in 3, and C3 in 9, with open fractures of Gustilo type?Uor ?Va in 7 cases. 11 cases were treated by the Ilizarov technique only. 10 cases were treated by the additional limited open reduction with screw, K-wire and fibular plating. The average time between injury and surgery was 4 days. We examined 6 cases treated with the vascularised fibular graft for the infectious non-union cases after internal fixation. Age at the surgery was from 19 to 70 (mean 46). Results: All fractures were united and removed at an average of 10 weeks (range 8–12 weeks). Complications included 5 cases of superficial pin tract infections. There is no deep infections and no pseudarthrosies. Conclusion: The use of Ilizarov fixator is a safer method of treatment of pilon fractures, especially for the severe soft tissue injury and we don ft delay surgery for soft tissue considerations

Pilon injuries without fibula fractures may be associated with increased tibial plafond fracture severity. To evaluate this, we used the rank order technique, with traumatologists blinded to the fibular injury, who ranked the radiographic severity of forty pilon injuries with and without fibula fractures. Pilon injuries with fibular fractures were ranked as more severe than those without. C-type injuries were ranked as more severe than B-type. Fibular fracture was more frequently associated with C-type injury than B-type. The presence of an intact fibula is not predictive of a more severe injury to the tibial pilon. To determine if the absence of a fibular fracture is predictive of tibial pilon fracture severity. Fibular status is not predictive of a more severe injury to the tibial pilon, and is more commonly associated with the less severe B-type injuries. Absence of an ipsilateral fibular fracture in patients with tibial pilon injuries may predict a more severe tibial plafond injury pattern. Presumably, the energy is completely absorbed by the tibia resulting in more severe epimetaphyseal injury. The reverse relationship, however, was identified. This fact may aid in prognosis and treatment strategies. Twenty consecutive pilon injuries without associated fibular fractures were matched 1:1 to an age/gender-matched cohort of pilon injuries with fibular fractures. Initial radiographs were digitized, the fibular image concealed, and then independently ranked (One, least severe; forty, most severe) by three orthopaedic traumatologists according to tibial plafond fracture severity. Injuries were classified using AO/OTA guidelines. Inter-observer agreement was moderate (κ =0.6). Mean rank for pilon injuries with fibula fractures was 24.4 versus 16.7 for those without (t = 0.02). C-type injuries demonstrated a mean of 10.3 for those with fibular fractures versus 8.7 for those without (t = 0.5). Mean rank for B-type injuries was 11.1 versus 24.5 for C-type injuries (t = 0.001). Overall, tibial pilon injuries with fibular fractures are more severe than those without. C-type injuries with or without fibular fractures are equally severe. C-type injuries were ranked significantly more severe than B-type. Fibular fracture was more frequently associated with C-type injury than B-type

We aimed to investigate the treatment and outcome of patients over 65 years of age with tibial Pilon fracture. Patients were treated by primary open reduction and internal fixation or external fixation (EF) as determined by local soft tissue conditions. Patient course, incidence of radiological osteoarthritis and functional outcome using the SF-36 questionnaire were recorded. All patients were evaluated serially until discharge from final follow-up. The mean follow-up time was 28 months (12-45). Statistical analysis was performed using Analyse-it(tm) software for Excel. In total 25 patients were studied. Two patients died before completion of treatment and were excluded from the final analysis. Therefore, 23 patients (10 male) were included with a mean age of 70.9 years (range 66-89) and a mean ISS of 10.25 (range 9-22). There were 4 grade IIIb open injuries. Three patients suffered superficial tibial wound infection. Two patients underwent early secondary amputation due to deep bone sepsis within 8 weeks of injury. One patient in the ORIF group underwent primary arthrodesis, which was subsequently revised due to non-union. 3 patients underwent secondary bone grafting to enhance healing, performed at 2, 6 and 9 weeks. 2 patients with metal work failure underwent subsequent revision of ORIF and progressed to union; the mean time to union was 33.8 weeks. At final follow-up 7 (28%) patients had radiological features of osteoarthritis but none had symptoms severe enough to warrant ankle arthrodesis. There were significant differences from the USA norm in physical function score, role physical score, and physical component score, (p< 0.01). Conclusion/Significance. In older patients local complications are relatively common and clinical vigilance must be maintained in order to allow appropriate intervention during their post-operative course. Despite the incidence of radiological post-traumatic arthrosis, none of the patients progressed to ankle fusion

Aims. Posterior malleolar (PM) fractures are commonly associated with ankle fractures, pilon fractures, and to a lesser extent tibial shaft fractures. The tibialis posterior (TP) tendon entrapment is a rare complication associated with PM fractures. If undiagnosed, TP entrapment is associated with complications, ranging from reduced range of ankle movement to instability and pes planus deformities, which require further surgeries including radical treatments such as arthrodesis. Methods. The inclusion criteria applied in PubMed, Scopus, and Medline database searches were: all adult studies published between 2012 and 2022; and studies written in English. Outcome of TP entrapment in patients with ankle injuries was assessed by two reviewers independently. Results. Four retrospective studies and eight case reports were accepted in this systematic review. Collectively there were 489 Pilon fractures, 77 of which presented with TP entrapment (15.75%). There were 28 trimalleolar fractures, 12 of which presented with TP entrapment (42.86%). All the case report studies reported inability to reduce the fractures at initial presentation. The diagnosis of TP entrapment was made in the early period in two (25%) cases, and delayed diagnosis in six (75%) cases reported. Using modified Clavien-Dindo complication classification, 60 (67%) of the injuries reported grade IIIa complications and 29 (33%) grade IIIb complications. Conclusion. TP tendon was the commonest tendon injury associated with pilon fracture and, to a lesser extent, trimalleolar ankle fracture. Early identification using a clinical suspicion and CT imaging could lead to early management of TP entrapment in these injuries, which could lead to better patient outcomes and reduced morbidity.

Introduction. Tibial Pilon fractures are potentially limb threatening, yet standards of care are lacking from BOFAS and the BOA. The mantra of “span, scan, plan” describes staged management with external fixation to allow soft tissue resuscitation, followed by a planning CT-scan. Our aim was to evaluate how Tibial Pilon fractures are acutely managed. Methods. ENFORCE was a multi-centre retrospective observational study of the acute management of partial and complete articular Tibial Pilon fractures over a three-year period. Mechanism, imaging, fracture classification, time to fracture reduction and cast, and soft tissue damage control details were determined. Results. 656 patients (670 fractures) across 27 centres were reported. AO fracture classifications were: partial articular (n=294) and complete articular (n=376). Initial diagnostic imaging mobilities were: plain radiographs (n=602) and CT-scan (n=54), with all but 38 cases having a planning CT-scan. 526 fractures had a cast applied in the Emergency Department (91 before radiological diagnosis), with the times taken to obtain post cast imaging being: mean 2.7 hours, median 2.3 hours, range 28 mins – 14 hours). 35% (102/294) of partial articular and 57% (216/376) of complete articular (length unstable) fractures had an external fixator applied, all of which underwent a planning CT-scan. Definitive management consisted of: open reduction internal fixation (n=495), fine wire frame (n=86), spanning external fixator (n=25), intramedullary nail (n=25), other (n=18). Conclusion. The management of Tibial Pilon fractures is variable, with prolonged delays in obtaining post cast reduction radiographs, and just over half of length unstable complete articular fractures being managed with the gold standard “span, scan, plan” staged soft tissue resuscitation. A BOFAS endorsed BOAST (British Orthopaedic Association Standard for Trauma) for Tibial Pilon fractures is suggested for standardisation of the acute management of these potentially limb threatening injuries, together with setting them apart from more straightforward ankle fractures

This study investigated concurrent talar dome injuries associated with tibial pilon fractures, mapping their distribution across the proximal talar dome articular surface. It compared the two main mechanisms of injury (MOI), falling from a height and motor vehicle accident (MVA), and whether the fractures were open or closed. From a previously compiled database of acute distal tibial pilon fractures (AO/OTA 43B/C) in adults of 105 cases, 53 cases were identified with a concurrent injury to the talar dome with a known mechanism of injury and in 44 it was known if the fracture was open or closed. Case specific 2D injury maps were created using a 1x1mm grid, which were overlayed in an Excel document to allow for comparative analyses. A two-way ANOVA was conducted that examined the effect of both MOI and if the fracture was open or closed on what percentage of the talar dome surface was injured. There was a statistically-significant difference between the average percentage of injured squares on the talar dome by both whether the fracture was open or closed (f(1)=5.27, p= .027) and the mechanism of injury (f(1)=8.08, p= .007), though the interaction between these was not significant (p= .156). Open injuries and injuries that occurred during an MVA were more likely to increase the surface area of the talar dome injuries. We have identified both MOI and if the fracture was either open or closed impacts the size of the injury present on the talar dome. Future research will investigate the aetiology of the differences noted, highlighting the clinical implications. Surgeons treating tibial pilon fractures caused by either a MVA or an open fracture, should be aware of an increased risk of large injuries to the surface of the talar dome

Tibial pilon fractures are typically the result of high-energy axial loads, with complex intra- articular fractures that are often difficult to reconstruct anatomically. Only nine simultaneous pilon and talus fractures have been published previously, but we hypothesised the chondral surface of the dome is affected more frequently. Data was acquired prospectively from 154 acute distal tibial pilon fractures (AO/OTA 43B/C) in adults. Radiographs, photographs, and intra-operative drawings of each case were utilised to document the presence of any macroscopic injuries of the talus. Detailed 1x1mm maps were created of the injuries in each case and transposed onto a statistical shape model of a talus; this enables the cumulative data to be analysed in Excel. Data was analysed using a Chi-squared test. From 154 cases, 104 were considered at risk and their talar domes were inspected; of these, macroscopic injuries were identified in 55 (52.4%). The prevalence of talar dome injury was greater with B-type fractures (53.5%) than C-type fractures (31.5%) (ρ = .01). Injuries were more common in men than women and presented with different distribution of injuries (ρ = .032). A significant difference in the distribution of injuries was also identified when comparing falls and motor vehicle accidents (ρ = .007). Concomitant injuries to the articular surface of the dome of the talus are relatively common, and this perhaps explains the discordance between the post-operative appearance following internal fixation and the clinical outcomes observed. These injuries were focused on the lateral third of the dome in men and MVAs, whereas women and fall mechanism were more evenly distributed. Surgeons who operatively manage high-energy pilon fractures should consider routine inspection of the talar dome to assess the possibility of associated macroscopic osteochondral injuries

Introduction. Pilon fractures are complex, high-energy, intra-articular fractures of the distal tibia. Achieving good outcomes is challenging due to fracture complexity and extensive soft tissue damage. The purpose of this study was to determine the long-term functional and clinical outcomes of definitive management with fine wire Ilizarov fixation for closed pilon fractures. Materials and Methods. 185 patients treated over a 14-year period (2004–2018) were included. All patients had Ilizarov frames applied to restore mechanical axis and fine wires to control periarticular fragments. CT scans were performed post operatively to confirm satisfactory restoration of the articular surface. All frames were dynamized prior to removal. Patients' functional outcome was assessed using the validated Chertsey Outcome Score for Trauma (“COST”). Review of clinical notes and imaging was used to determine complications and time to union. Results. The mean functional outcome in the studied cohort was determined to be “average” on the “COST” score. Poorer functional outcomes were associated with younger age at time of injury and multi-fragment fracture patterns. Mean time in frame was 170 days. Complication rates were low. There were no deep infections, no amputations and only 8 patients went on to have ankle fusions. Conclusions. Good functional results and low complication rates can be achieved by managing pilon fractures with fine wire Ilizarov fixation. Nonetheless, at time of injury patients should be counselled as to the severity of the injury and impact on their functional status

Introduction. The BOAST (British Orthopaedic Association Standards for Trauma) guidelines do advise that open pilon fractures amongst other open lower limb fractures need to be treated at a specialist centre with Orthoplastic care. The purpose of this study was to determine clinical outcomes in patients with open pilon fractures treated as per BOAST guidelines including relatively aggressive bone debridement. Methods. A retrospective analysis of a single surgeon series of open pilon fractures treated between 2014 and 2019 was conducted. Injuries were graded according to the Gustillo-Anderson classification and all patients were included for the assessment of the rate of infection and fracture healing. Functional outcome assessment was performed in all patients according to the American Orthopedic Foot and Ankle Score (AOFAS) at 6 months after definitive surgery. Initial wound with bone debridement and application of a spanning external fixator was performed within an average of 13.5 (Range: 3–24) hours. Fixation with FWF (Fine Wire Frame) was performed when the wound was healed, with the mean time from primary surgery to application of FWF being 24.5 (Range: 7–60) days. Results. There was a total of 20 patients including 16 males and 4 females. The mean age was 50.45 (Range: 16–88) years. Follow-up was for an average of 23.2 (Range: 5–51) months. There were 3 patients with Gustilo Type I injuries, 6 with Type II, 4 Type with type IIIa and 7 with Type IIIb injuries. Average time to bone union was 9.3 (Range: 2–18) months. The mean AOFAS score was 66 (Range: 15–97) points. TSF was used on 18 patients, while 2 patients had an Ilizarov frame. A corticotomy was performed on 4 patients with critical bone defect post debridement, while 2 patients had Stimulan beads with antibiotics. There was 1 case (5%) of deep infection and 9 cases (45%) of superficial infection. There were also 2 cases (10%) of non-union which required bone grafting from their femur using a RIA (Reamer Irrigation Aspirator). Other complications included 1 case of acute compartment syndrome, 1 case of pulmonary embolism, 1 case of necrotic skin and 1 case of amputation. Conclusion. Results of our study suggests that the use of staged wound debridement including relatively aggressive bone debridement in conjunction with antibiotics, external fixators and patient tailored conversion from spanning external fixator to fine wire frame achieves low rates of wound infection and complications for patients with open pilon fractures

Introduction and Objective. Despite the low incidence of pilon fractures among lower limb injuries, their high-impact nature presents difficulties in surgical management and recovery. Current literature includes a wide range of different management strategies, however there is no universal treatment algorithm. We aim to determine clinical outcomes in patients with open and closed pilon fractures, managed using a treatment algorithm that was applied consistently over the span of this study. Materials and Methods. This retrospective study was conducted at a single institution, including 141 pilon fractures in 135 patients, from August 2014 to January 2021. AO/OTA classification was used to classify fractures. Among closed fractures, 12 had type 43A, 18 had type 43B, 61 had type 43C. Among open fractures, 11 had type 43A, 12 had type 43B, 27 had type 43C. Open fractures were further classified with Gustilo-Anderson (GA); type 1: n=8, type 2: n=10, type 3A: n=12, type 3B: n=20. Our treatment algorithm consisted of fine wire fixator (FWF) for severely comminuted closed fractures (AO/OTA type 43C3), or open fractures with severe soft tissue injury (GA type 3). Otherwise, open reduction internal fixation (ORIF) was performed. When required, minimally invasive osteosynthesis (MIO) was performed in combination with FWF to improve joint congruency. All open fractures, and closed fractures with severe soft tissue injury (skin contusion, fracture blister, severe oedema) were initially treated with temporary ankle-spanning external fixation. For all open fracture patients, surgical debridement, soft tissue cover with a free or pedicled flap were performed. For GA types 1 and 2, this was done with ORIF in the same operating session. Those with severe soft tissue injury (GA type 3) were treated with FWF four to six weeks after soft tissue management was completed. Primary outcome was AOFAS Ankle-Hindfoot score at 3, 6 and 12-months post-treatment. Secondary outcomes include time to partial weight-bear (PWB) and full weight-bear (FWB), bone union time. All complications were recorded. Results. Mean AOFAS score 3, 6, and 12 months post-treatment for open and closed fracture patients were 44.12 and 53.99 (p=0.007), 62.38 and 67.68 (p=0.203), 78.44 and 84.06 (p=0.256), respectively. 119 of the 141 fractures healed without further intervention (84.4%). Average time to bone union was 51.46 and 36.48 weeks for open and closed fractures, respectively (p=0.019). Union took longer in closed fracture patients treated with FWF than ORIF (p=0.025). On average, open and closed fracture patients took 12.29 and 10.76 weeks to PWB (p=0.361); 24.04 and 20.31 weeks to FWB (p=0.235), respectively. Common complications for open fractures were non-union (24%), post-traumatic arthritis (16%); for closed fractures they were post-traumatic arthritis (25%), superficial infection (22%). Open fracture was a risk factor for non-union (p=0.042; OR=2.558, 95% CI 1.016–6.441), bone defect (p=0.001; OR=5.973, 95% CI 1.986–17.967), and superficial infection (p<0.001; OR=4.167, 95% CI 1.978–8.781). Conclusions. The use of a two-staged approach involving temporary external fixation followed by definitive fixation, provides a stable milieu for soft tissue recovery. FWF combined with MIO, where required for severely comminuted closed fractures, and FWF for open fractures with severe soft tissue injury, are safe methods achieving low complication rates and good functional recovery

Purpose. Pilon fracture is a severe injury which has a great impact on the patients' lives, but in what extend is not clear yet in the literature. The purpose of this study was to investigate the gait alternations after treatment of patients who had pilon fractures. Materials & Methods. We have evaluated the gait pattern of patients who were treated with circular Ilizarov frame following pilon fractures in our department. The gait was tested by using a force plate in a walking platform. Ground Reaction Forces (GRF) and timing of gait phases data were collected during level walking at self-selected speeds. The patients performed two walking tasks for each limb and the collected data were averaged for each limb. Demographic, clinical, radiological, trauma outcome (COST) and quality of life questionnaire (SF-12) data were also collected. Results. We have analysed the gait through the GRF of twelve patients (aged 44.9 ±12.4 years), who had undergone treatment with circular Ilizarov frame following pilon fractures (67% were male). The tests were performed at an average of 10.5 months after the initial treatment. SF-12 Mental scores have returned to normal (mean 56.4 ±11.6) but physical scores remained impaired (mean 41.8 ±8.4). COST questionnaire scores reached average levels (47.1 ±15) in all dimensions (Symptoms: 51.4 ±16, Function: 44 ±14 and Mental Status: 56.6 ±16). During the push-off phase all the plantar flexor muscles are activated and the ankle plantar flexes to achieve the push off. It seems that this motion, is not achieved adequately with the affected limb and the patients are using their normal limb earlier (pre-swing is the start of the double support of the gait) in order to progress in their gait circle. Conclusions. Ten months following treatment with circular ilizarov frame for pilon fracture the patients still have impaired gait pattern. The differences can be explained by the lack of plantar flexion of the ankle which results to poorer push-off of the affected limb

Abstract. Objectives. Current literature on pilon fracture includes a range of different management strategies, however there is no universal treatment algorithm. We aim to determine clinical outcomes in patients with open and closed pilon fractures, managed using a treatment algorithm applied consistently over the span of this study. Methods. 135 patients over a 6-year period were included. Primary outcome was AOFAS score at 3, 6, 12-months post-injury. Secondary outcomes include time to partial weight-bear (PWB), full weight-bear (FWB), bone union time, follow-up time. AO/OTA classification was used (43A: n=23, 43B: n=30, 43C: n=82). Treatment algorithm consisted of fine wire fixator (FWF) for severely comminuted closed fractures (AO/OTA type 43C3), or open fractures with severe soft tissue injury (GA type 3). Otherwise, open reduction internal fixation (ORIF) was performed. When required, minimally invasive osteosynthesis was performed in combination with FWF to improve joint congruency. Results. Mean AOFAS score 3, 6, and 12 months post-treatment for open and closed fracture patients were 44.12 and 53.99 (p=0.007), 62.38 and 67.68 (p=0.203), 78.44 and 84.06 (p=0.256), respectively. 119 of 141 fractures healed without further intervention (84.4%). Average time to union was 51.46 and 36.48 weeks for open and closed fractures, respectively (p=0.019). On average, open, and closed fracture patients took 12.29 and 10.76 weeks to PWB (p=0.361); 24.04 and 20.31 weeks to FWB (p=0.235), respectively. Common complications for open fractures were non-union (24%), post-traumatic arthritis (16%); for closed fractures they were post-traumatic arthritis (25%), superficial infection (22%). Open fracture was a risk factor for non-union (p=0.042;OR=2.558,95% CI 1.016–6.441), bone defect (p=0.001;OR=5.973,95% CI 1.986–17.967), and superficial infection (p<0.001;OR=4.167,95% CI 1.978–8.781). Conclusions. FWF with minimally invasive osteosynthesis, where required for severely comminuted closed fractures, and FWF for open fractures with severe soft tissue injury, are safe methods achieving low complication rates and good functional recovery

Introduction. Ashford and St Peter's Hospital (ASPH) is a district general hospital in Chertsey, Surrey. It is a tertiary referral unit offering a circular frame service to manage complex trauma patients in the South East of England. This study analyses the patient pathway in 66 consecutive tertiary referrals from 2015–2020. All patients were managed with an Ilizarov frame for either a tibial plateau fracture or pilon fracture. Materials and Methods. The patient journey of 66 consecutive tertiary referrals for tibial plateau and pilon fractures were analysed. The following data was captured: patient demographics; type of injury; referring centre; date of injury; date of referral; date of arrival at ASPH; date of surgery and date of discharge. Using this data we aimed to identify areas of the pathway that can be improved. In addition, the 66 patients were split into two groups of 33 patients. 33 patients were referred via an electronic referral platform and 33 patients were referred verbally prior to the implementation of the electronic referral platform. The groups were compared to see the impact of an electronic referral platform on the patient's journey. Results. Average age 45 (range 17–88 years), Male percentage 54.55%, 45 tibial plateau patients, 21 pilon patients. Injury to Admission at ASPH- 6 days (median), Injury to Surgery 8 days (median), Surgery to Discharge 4 days (median), Total stay in ASPH 6 days (median). Conclusions. The biggest delay in our tertiary referral pathway is from referral to arrival at ASPH. The implementation of an electronic referral pathway has not improved times from referral to arrival at ASPH. Ring fenced beds for tertiary referrals would be the greatest way to improve flow through the pathway and reduce the complications related to delayed surgery

The anterolateral surgical exposure to the distal tibia for pilon fractures has become more popular. One of the potential benefits over the commonly used anteromedial approach is a reduction in wound complications due to the improved soft tissue coverage of the anterolateral tibia. Minimal data exists regarding the rate of complications with the anterolateral approach. The purpose of this study was to evaluate wound complications in the early postoperative period associated with the use of the anterolateral approach for pilon fractures. Methods: A retrospective review was conducted to identify all operatively treated pilon fractures at our university level 1 trauma center from September 2005 through July 2007. Sixty-eight pilon fractures were identified. All patients were treated with a staged protocol utilizing immediate external fixation followed by delayed open reduction and internal fixation based upon the condition of the soft tissue envelope. Patients who had an anterolateral surgical approach were identified and their medical records were reviewed for the first six weeks postoperatively to determine the rate of wound complications. The endpoint of six weeks was chosen to identify complications related to the surgical exposure alone. Results: Thirty-six of the sixty-eight patients with pilon fractures had an anterolateral surgical exposure. One additional patient had an anterolateral incision performed for revision of a previously treated pilon fracture. 97% of these fractures were AO/OTA 43-C (three C1, nine C2, and twenty-three C3). The median time delay to definitive fixation was 19 days (10–38 days). Sixteen (44.4%) of the fractures were open, ten of which were Gustilo type III (five IIIA, four IIIB, and one IIIC). Eight of the thirty-seven patients had wound complications related to the anterolateral incision within the first six weeks of definitive fixation. Six patients (16%) had minor complications which were successfully treated with dressing changes and oral antibiotics, and two (5%) had major complications, with evidence of deep wound infection that required formal irrigation and debridement. Conclusion: In a case series with a high rate of complex open pilon fractures, open reduction and internal fixation utilizing an anterolateral approach provided good exposure of the distal tibia with a low incidence of early wound complications. Significance: Pilon fractures, especially high energy complex open ones, have a high risk of wound complications. Avoiding complications is the key in managing high energy pilon fractures. This case series provides evidence that the anterolateral approach has a low rate of wound complications in the most complex pilon fractures

Introduction. We present a case of a 49-year-old patient who initially presented in May 2020 with an open pilon fracture. Managed with initial debridement, fixation and flap - who subsequently underwent circular frame application for failure of fixation, requiring a transport to fusion frame who developed beta-haemolytic streptococcus A within the site of the proximal corticotomy. Materials & Methods. A systematic review of the literature was conducted searching EMBASE, MEDLINE and Cochrane library for all articles discussing infected bone regenerate- a paucity of information was found. Abstracts were independently reviewed by 2 authors (LH and LT). In total, there were 16 papers, and then subsequently analysed we identified two case reports regarding infected regenerate. Results. Developing an infection in a regenerate is highly rare with very few reported cases within the published literature. The literature identified risk factors for an infected regenerate, with open fracture and smoking being the two consistent factors. The open fracture deep infection rate is cited at 10% in most publications, this is at the site of the open fracture and not within the regenerate. Conclusions. Infection within the regenerate during distraction osteogenesis is highly unusual, with only two other published papers in the literature to the best of our knowledge. This should be borne in mind when managing patients with infection of unknown sources in cases of distraction osteogenesis

Introduction. Intra articular distal tibia fractures can lead to post-traumatic osteoarthritis. Joint distraction has shown promise in elective cases. However, its application in acute fractures remains unexplored. This pilot study aims to fill this knowledge gap by investigating the benefits of joint distraction in acute fractures. Materials & Methods. We undertook a restrospective cohort study comprising patients with intra-articular distal tibia and pilon fractures treated with a circular ring fixator (CRF) at a single center. Prospective data collection included radiological assessments, Patient-Reported Outcome Measures (PROM), necessity for additional procedures, and Kellgren and Lawrence grade (KL) for osteoarthritis (OA). 137 patients were included in the study, 30 in the distraction group and 107 in the non-distraction group. There was no significant difference between the groups. Results. Mean follow-up was 3.73 years. There was no significant difference between the groups in overall complications or need for further procedures. There was no significant difference in progression of KL between the groups (1.81 vs 2.0, p=0.38) mean follow up 1.90 years. PROM data was available for 44 patients (6 distraction, 38 non-distraction) with a mean follow-up of 1.71 years. There was no significant difference in EQ5D (p=0.32) and C Olerud-H Molander scores (p=0.17). Conclusions. This pilot study suggests that joint distraction is safe in the acute setting. However, the study's impact is constrained by a relatively small patient cohort and a short-term follow-up period. Future investigations should prioritise longer-term follow-ups and involve a larger patient population to more comprehensively evaluate the potential benefits of joint distraction in acute fractures

Fractures of the ankle are common, and they mostly affect young adults. Wound complications are not uncommon following the fixation of these fractures. This study evaluated the impact of HIV on wound healing after plate osteosynthesis in patients with closed ankle fractures. This is an observational retrospective study of patients operated on at a tertiary level hospital. We reviewed hospital records for patients above 18 years of age who presented with wound breakdown following ankle open reduction and internal fixation. The patients’ hospital records were retrieved to identify all the patients treated for closed ankle fractures and those who developed wound breakdown. Patients with Pilon fractures were excluded. The National Health Laboratory System (NHLS) database was accessed to retrieve the CD4 count, viral load, haematology study results, and biochemistry results of these patients at the time of surgery and subsequent follow-up. The x-rays were retrieved from the electronic picture archiving system (PACS) and were assessed for fracture union at a minimum of 3 months follow-up. We reviewed the medical records of 172 patients with closed ankle fractures treated from 2018 to 2022. Thirty-one (18.0%) developed wound breakdown after surgery, and they were all tested for HIV. Most of the patients were male (58.0%), and the average age of the cohort was 43.7 years (range: 21 years to 84 years). Ten of these patients (32.2%) were confirmed HIV positive, with CD4 counts ranging from 155 to 781. Viral load levels were lower than detectable in 40% of these patients. All patients progressed to fracture union at a minimum of 3 months follow-up. We observed no difference between HIV-positive and HIV-negative patients in terms of wound breakdown and bone healing post-plate osteosynthesis for closed ankle fractures

Treatment of posterior malleolar (PM) ankle fractures remain controversial. Despite increasing recommendation for small PM fragment fixation, high quality evidence demonstrating improved clinical outcomes over the unfixated PM is limited. We describe the medium-to-long term clinical and radiographical outcomes in younger adult patients with PM ankle fractures managed without PM fragment fixation. A retrospective cohort study of patients aged 18–55 years old admitted under our orthopaedic unit between 1st of April 2009 and 31st of October 2013 with PM ankle fractures was performed. Inclusion criteria were that all patients must mobilise independently pre-trauma, have no pre-existing ankle pathologies, and had satisfactory bimalleolar and syndesmotic stabilisation. Open fractures, talar fractures, calcaneal fractures, pilon fractures, subsequent re-injury and major complications were excluded. All PM fragments were unfixated. Clinical outcomes were evaluated using Foot and Ankle Ability Measure (FAAM) with activities of daily living (ADL) and sports subscale, visual analogue scale (VAS) and patient satisfaction ratings. Osteoarthrosis was assessed using modified Kellgren-Lawrence scale on updated weightbearing ankle radiographs. 61 participants were included. Mean follow-up was 10.26 years. Average PM size was 16.19±7.39%. All participants were evaluated for clinical outcomes, demonstrating good functional outcomes (FAAM-ADL 95.48±7.13; FAAM-Sports 86.39±15.52) and patient satisfaction (86.16±14.42%), with minimal pain (VAS 1.13±1.65). Radiographical outcomes were evaluated in 52 participants, showing no-to-minimal osteoarthrosis in 36/52 (69.23%), mild osteoarthrosis in 14/52 (26.92%) and moderate osteoarthrosis in 2/52 (3.85%). Clinical outcomes were not associated with PM fragment size, post-reduction step-off, dislocation, malleoli fractured or syndesmotic injury. PM step-off and dislocation were associated with worse radiographical osteoarthrosis. Other published medium-to-long term studies reported overall good outcomes, with no differences after small fragment fixation. The unfixated smaller posterior malleolus fragment demonstrated overall satisfactory clinical and radiographical outcomes at 10-year follow-up and may be considered a valid treatment strategy

Aim. A prospective cohort of patients undergoing total ankle arthroplasrty for arthritis following pilon fractures was included in the present study. This group of patients generally have poor soft tissue envelope and have had previous surgical interventions prior to the ankle arthroplasty, making the arthroplasty more difficult as well as prone to complications. Methods. The data collected included patient demographics, American Orthopaedic Foot and Ankle Score (AOFAS) and patient reported outcomes (FAOS, SF-36, patient satisfaction) The data was collected preoperatively and at 1 & 2 years postoperatively. The minimum follow-up period was 2 years post-operatively. Results. A total of 167 total ankle arthroplasties were performed by the senior author between Jan 2006 and June 2010. Of this cohort, the indication for 12 arthroplasties was arthritis following pilon fractures of the distal tibia. The average of the patients at the time of the surgery was 64.2yrs. The average number of previous surgeries prior to the ankle arthroplasty was 1.5. There were significant improvements in the AOFAS scores from an average of 18 to 75 at final review. The WOMAC scores improved from 31 to 71 for pain, stiffness improved from 31 to 60 and function improved from 33 to 63. The improvement of the SF36 and patient satisfaction score is similar to the ones for primary ankle osteoarthritis. The complications were: 1 case of superficial wound infection which settled with antibiotics, one fracture of medial malleolus and one case of undisplaced distal tibial fracture treated conservatively to union. Conclusion. The Indications for TAR can be safely broadened to include younger patients with arthritis following pilon fractures of the tibia. The Outcomes after TAR for patients with arthritis following pilon fractures are comparable to those for primary osteo arthritis of the ankle

Purpose: Pilon fractures demonstrate complex osseous and soft tissue injury. Protocols involving immediate tibial reduction and external fixation, with or without fibular fixation, then delayed definitive fixation result in decreased complications. Our purpose was to evaluate the treatment course of pilon fractures provisionally stabilised at outside institutions and subsequently transferred, focusing on the incidence and reasons for revision procedures, and subsequent complication rates. Method: An institutional trauma database was retrospectively reviewed, demonstrating 668 pilon fractures treated at our institution between 2000–2007. Of these, 39 patients with 42 fractures had a temporising surgical procedure prior to referral. Demographics, injury characteristics, reason for revision, and subsequent complications were determined. Clinical follow-up averaged 60 weeks (range, 1 to 281). Results: Mean age was 41 years (range, 18–78). Twenty-two fractures (52%) were open; 38 (90%) demonstrated a fractured fibula. Referral occurred an average of 5.8 days (range, 1–20) after initial stabilization. Pre-transfer fixation was revised in 40 fractures (95%). Reasons for revision included tibial malreduction (33 fractures, 83%), fibular malreduction (4 fractures, 10%), pins in the proposed incision (5 fractures, 13%), or loose pins (3 fractures, 8%). Of the 34 fractures with distal pins, 24 (71%) required revision for pin malposition, loosening, drainage, talar placement, or extraosseous placement. Late complications occurred in 14 fractures (33%), including deep infection in 10 (24%), and non-union in 3 (7%). Twenty-three patients (55%) required additional procedures following definitive fixation, including 9 soft tissue coverage procedures and 3 amputations. Conclusion: The majority of patients with pilon fractures treated with provisional stabilisation followed by referral to our institution required revision prior to definitive fixation. This resulted in many avoidable additional procedures, and a higher complication rate than recent contemporary controls. The authors recommend that, when possible, the initial and definitive management of these injuries be performed at the accepting institution

Clinical Problem. Pilon fractures and distal metaphyseal fractures of the tibia are associated with a high rate of soft tissue and bone healing problems. We started to use the XS and XS nail as minimal invasive procedure for the management of these fractures in July 2000 first for the fibula and since for the fibula and pilon itself but extended metaphseal comminution are contraindication for the XS nail. Because of soft tissue problems and higher loading capacity of intramedullary implants the XS Nail was also used for ankle fracture osteosynthesis but as in all articular fractures with open reduction,. Material and Methods. the XS nail is a 4.5mm or the XXS a 3.5mm straight nail witch is locked by threaded wires witch are placed with an aiming device and allows also dynamic fracture site compression with a set screw. The Fibula is fixed percutaneusly and after distal locking with traction of the aiming device also tibia length and axis can be restored and fixed with the proximal locking. From july 2000 to july2006 54 pilon fractures where treated. The mean age was 54 years (range 25–92). In all cases except one referred after 4 weeks the fibula and joint dislocations where stabilised primarily. The tibia XS nail osteosynthesis or limited invasive plate fixation was performed after 5–8 days except two fixed primarily. Up to now 43 patients could be re-examined more than 12 months after surgery. The results were classified according to the Ovadia Score. In a second study: from 05/2000 to 03/2002 214 ankle fractures were stabilised with a XS or XXS nail. The mean age was 51 year, 59% were woman. 35% were Weber B and 25% type C fractures. The re-examination after 6 months could be performed in 91 Patients and was evaluated according to the Ovadia score (clinical and radiological). Results. All articular pilon fractures and fibula fractures healed without problems but in 3 metaphyseal fractures delayed union required bone grafting. According to the Ovadia Score after one year the results were very good or good in the subjective criteria in 69% of the patients and 61% in the objective criteria. In the ankle fractures study in 2 patients haematoma revisions and in 2 patients with the primary used oblique insertion of the nail a proximal fibula fracture occured. At re-examination 71% showed an excellent and 25% a good result. Conclusion. the minimal invasive stabilisation of pilon fractures with the XS nail and the absence of plates on the bone surface reduces significantly the healin. The Xs nail is also a new option for ankle stabilisation. It improves the stability and reduces the complication of ankle osteosynthesis due to the lack of implant under the skin on the bone surface and due to the higher biomechanical stability of intramedullary implants

Non-unions of pilon fractures are difficult Orthopaedic problems. Significant bone loss and infection can lead to amputation. Joint stiffness in conjunction with disuse osteopenia make stabilization in this area challenging. We present the use of a custom blade plate design that offers sufficient stability for successful treatment in six successive cases. With a mean follow-up of thirty-three months, all fractures treated with this method healed. The five infected cases healed without recurrence of infection. With average scores of 70.7 on the Maryland Foot Score, and sixty-eight on the Foot and Ankle Society Ankle-Hindfoot Scale, the patients overall had satisfactory results. The purpose of this study was to describe a new technique of treating non-unions of distal tibia pilon fractures using a custom blade plate design. A report of successful outcomes in six consecutive cases. A retrospective analysis of fifty-six pilon fractures treated over a three- year period revealed six patients with significant complications related to their fractures. Of these, all had significant bone loss and five were infected. All six failures were revised using a custom blade plated design with oblique locking screws for triangular fixation of the distal pilon. The average follow-up period was thirty-three months. These patients were evaluated with the Maryland Foot Score (MFS) and the Foot and Ankle Society Ankle-Hindfoot Scale (AHS). All of the six patients treated with the proposed method went on to heal without recurrence of infection. Three patients required additional surgical interventions including bone grafting, debridement and hardware removal to achieve the final result. Their average MFS and AHS were 70.7 and sixty-eight respectively. Stable fixation is an absolute necessity for a successful outcome in the failed pilon fracture. A custom blade plate design with oblique interlocked screws offers sufficient long-term stability, despite infection and disuse osteopenia, for healing of the non-united fracture to occur. As shown by our series, satisfactory clinical results can be expected and amputation can be avoided in complicated cases using this surgical technique

Introduction: The pilon fracture extending from the distal tibial metaphysis into the ankle joint represents one of the most challenging injuries faced by orthopaedic surgeons. Achieving the ideal of anatomic reduction and stable fixation is often impeded by the frequently severe soft tissue injuries associated with these fractures. In June 2004 we began treating intra-articular pilon fractures by minimally invasive techniques. Methods: The minimally invasive technique used involves reduction of the fracture by ligamentotaxis with the use of the traction table and manipulation of the foot to correct rotation, varus/valgus, pro/recurvatum. Any further reduction where necessary was performed using an ankle arthroscope and a probe introduced through stab incisions anteriorly. Following reduction a distal tibial locking plate was applied percutaneously to the medial of the tibia. Locking screws were then inserted percutaneously. All significant anterior or posterior distal tibial fragment were fixed separately with an anterior percutaneously inserted interfragmentary compression screw. We compared all cases of closed intra-articluar fractures (AO types C2 and C3) fixed by the method described above in a one year period (June 2004 – June 2005) – Group 1 (n = 26), with the immediate previous one year period (June 2003 – June 2004) of matched closed fracture pattern fixed by formal open reduction and internal fixation – Group 2 (n = 16). Mean follow up was 26 months. All bony and soft tissue complications were recorded. A specific assessment of foot and ankle outcome was undertaken using the American Orthopaedic Foot and Ankle Score (AOFAS). Scoring was undertaken on two separate occasions at a mean of 9 and 24 months post operatively, by orthopaedic surgeons blinded to the treatment modality. The mean of the two scores was then recorded. It has been previously demonstrated that the functional outcome in pilon fractures improves for approximately 2 years after injury. Results: We observed a much higher incidence of complications in the open reduction group when compared with the minimally invasive group. An excellent AOFAS result was obtained in 83% (20/24) of the patients in the minimally invasive group, the same result was achieved in only 12.5% of the formal open reduction and fixation group. Conclusion – The use of the minimally invasive reduction method described here in combination with the insertion of percutaneous fixation, in the form a medial locking plate with or without additional percutaneously inserted antero-posterior screws represents a valuable method of treating the most complex of closed pilon fractures

Introduction and Objective. Lower limb fractures are amongst the most common surgically managed orthopaedic injuries, with open reduction and internal fixation (ORIF) as the conventional method of treatment of the fibula. In recent years, dedicated intramedullary implants have emerged for fibula fixation in tandem with the move towards minimally invasive surgery in high-risk patients. This is the largest multicentre review to date with the aim of establishing the clinical outcomes following intramedullary nail (IMN) fixation of the fibula and to identify the absolute indication for fibula IMN fixation. Materials and Methods. A retrospective study of adult patients in all UK hospitals, who underwent fibula nail fixation between 01/01/2018 and 31/10/2020 was performed. Primary outcome measures included time to union, infection rate, other post-operative complications associated with the fixation and length of hospital stay. The secondary outcome measure was to identify the indication for fibula nailing. Data tabulation was performed using Microsoft Excel and analysis was performed using SPSS Version 23 (SPSS Statistics). Results. 2 Major Trauma Centres (MTCs) and 9 Trauma Units (TUs) were eligible for inclusion. 102 patients were included and 91% were classified as ankle fractures of 68% (n=69) were Weber B, 24% (n=24) Weber C and 8% (n=9) were either distal tibial fractures with an associated fibula fracture or pilon fractures. The mean age was 64 years of which 45 were male patients and 57 were female. The average BMI was 30.03kg/m. 2. and 44% of patients were ASA 3. 74% of patients had poor pre-op skin condition including swelling and open wounds. The calculated infection rate for fibula nail was 4.9% and metal-work complication rate was 4.9%. The average time to union was 13 weeks and length of inpatient stay was 15 days (SD +/− 12 days). Conclusions. MEFNO has demonstrated that fibula nail is an ideal implant in patients who have a physiologically higher risk of surgery, poor skin condition and a complex fracture pattern. The time to union, complication and infection risks are lower than that reported in literature for ankle ORIFs

Fractures of distal femur and tibia treated with Open Reduction and Internal Fixation (O.R.I.F.) are frequently complicated in the postoperative period. Minimal Invasive Plate Osteosynthesis (MIPO) is developing for subcutaneous plating. The purpose of this study is to demonstrate the improvement in dropping the risks of complications following internal fixation of closed fractures of the lower limb using MIPO in comparison with conventional O.R.I.F. procedure. From January 1998 to May 1999 we collected 32 cases of lower limb fractures (10 distal femur, 15 pilon, 7 distal tibia) treated with O.R.I.F procedure (Group I). The mean age was 47.6 years (range 23–76). From June 1999 we started to perform MIPO in closed fractures of lower limb with conventional devices (36 cases). From March 2001 we performed part of our minimal invasive surgery (54 cases) with new devices with angular stability (Less Invasive Stabilization System, Synthes) that offer more tools for subcutaneous osteosynthesis and more mechanical stability of the implants. Our 90 cases formed Group II. The mean age was 53.2 years (range 21–80). The mean follow up was 18 months. We used bone grafts in only 1 case of severe pilon fracture. In Group I we got 2 infections in pilon fractures, 3 delayed union in distal tibial fractures, 1 non-union in distal femoral fracture, 1 varus deformity in distal femoral fracture and 2 DVT. In Group II we had no infection, no delayed or non-union (a mean consolidation time of 8–10 weeks for pilon fractures, 6 weeks for distal tibia fractures, 10–12 for distal femoral and proximal tibia ones). 2 cases of varus deformity in 1 pilon fractures (1 MIPO); 1 DVT in distal tibial fracture; 2 cases of varus deformity of distal femoral fracture (1 DCS). Conventional O.R.I.F. surgery showed some limits: wide exposure, damage to vascular supply of soft tissues and bone, blood loss, high risk of infections, not indicated in polytrauma patient: international literature reported high rate of postoperative complications. The findings of this study justify the effort to follow this procedure also because the new devices available improved mechanical stability and facilitated this technique In conclusion, minimal invasive surgery is a demanding technique with undoubted advantages: it reduces surgical exposures and risk of infection; it respects the biology of callus and soft tissues, it reduces the necessity of bone graft and is particularly indicated in polytrauma patients

Background. The optimal treatment for pilon fractures remains controversial. We have used early single-stage open reduction and internal fixation to treat these injuries and the purpose of this study was to determine the safety and efficacy of this strategy. Methods. A cohort of 95 patients with AO type C tibial pilon fractures underwent primary ORIF. Of these patients, 21 had open fractures. Sixty-eight fractures were sustained in falls, 21 in motor vehicle collision, 5 in crushes and one in an aircraft crash. The principal outcome measure was wound dehiscence or infection requiring surgery. Radiological and functional outcomes were assessed at a mean of five years using the SF36 and the Foot and Ankle Outcome Score. Results. Primary ORIF was performed within 48 hours of admission in 98% cases. Reduction was anatomical in 90% cases. Six (6%) patients developed a wound infection or dehiscence that required surgical débridement, giving a wound complication rate of 4/21 (19%) for open fractures and 2/74 (2.7%) for closed fractures. Of the two closed fractures, one occurred in a patient with local scarring from previous trauma, insulin-dependent diabetes mellitus and chronic alcohol abuse, and the other in a patient with schizophrenia, diabetes and peripheral neuropathy. Radiographic follow-up revealed 74% patients had normal appearances or mild osteoarthritic degeneration only. Functional outcomes revealed a reduced level of general health and mild disability. Conclusions. Provided surgery is performed expeditiously by experienced orthopaedic trauma surgeons, AO type C pilon fractures can be stabilised safely and effectively by primary ORIF, with very low rates of wound complications, a high quality of reduction, and a good long term outcome. These results compare favourably with the published results for all other methods of treatment

Background. Tibial pilon fractures lead to complicated therapeutic problem. Application in these cases of external fixators which are composed of an active articulated joint hinge imitating movement in the region of upper ankle joint, which allows plantar and dorsal flexion, leads to functional treatment of distal tibia fractures. Aim. The aim of the study was to present the four year experience with an evaluating biomechanical parameters, medical properties and clinical usefulness of the external fixator Dynastab-S in the treatment of tibial pilon fractures. Material. Observations were based on patients hospitalized in Orthopedic and Rehabilitation Department of Medical University of Warsaw in a period from March 2000 to August 2004. The average period of observations was 29 months. Inclusion criteria were based on the algorithm which was created in our department. Results. The assessment of biomechanical parameters of bone-fixator arrangement proved usefulness and safeness of the external fixator Dynastab-S. The positive results of clinical examinations, X-ray examinations and subjective opinion of the patients encourages to wide use of the external fixator Dynastab-S in the treatment of tibial pilon fractures

Introduction: The pilon fracture extending from the distal tibial metaphysis into the ankle joint represents one of the most challenging injuries faced by orthopaedic surgeons. Achieving the ideal of anatomic reduction and stable fixation is often impeded by the frequently severe soft tissue injuries associated with these fractures. In June 2004 we began treating intra-articular pilon fractures by minimally invasive techniques. Materials and Methods: The minimally invasive technique used involved reduction of the fracture by ligamentotaxis and manipulation of the foot to correct rotation, varus/valgus, pro/recurvatum. Any further reduction was performed using an ankle arthroscope and a probe introduced through stab incisions. Following reduction a distal tibial locking plate was applied percutaneously to the medial of the tibia. All significant anterior or posterior distal tibial fragments were fixed separately with an anterior percutaneously inserted interfragmentary compression screw. We compared all cases of closed intra-articluar fractures (AO types C2 and C3) fixed by the method described above in a one year period (June 2004 – June 2005) – Group 1 (n = 26), with the immediate previous one year period (June 2003 – June 2004) of matched closed fracture pattern fixed by formal open reduction and internal fixation – Group 2 (n = 16). Mean follow up was 26 months. All bony and soft tissue complications were recorded. A specific assessment of outcome was undertaken using the American Orthopaedic Foot and Ankle Score (AOFAS). Scoring was undertaken on two separate occasions at a mean of 9 and 24 months post operatively. Results: We observed a far greater incidence of complications in the open reduction group when compared with the minimally invasive group. An excellent AOFAS result was obtained in 83% (20/24) of the patients in the minimally invasive group, the same result was achieved in only 12.5 % of the formal open reduction and fixation group. Conclusion: The use of the minimally invasive reduction method described here in combination with the insertion of percutaneous fixation, represents a valuable method of treating the most complex of closed pilon fractures

Aims: Fibular plating comprises a major component in the treatment of Pilon fractures with ORIF. However its necessity in fractures treated by EX.FIX has been questioned. In order to clarify this technical detail we carried out a retrospective study with Pilon fractures treated by circular þxators. Methods: Between 1992–2001, 65 pilon fractures were treated with circular þxators. Fractures were classiþed according to the systems of Ruedi Ð All-gower (9 II, 56 III) and Ovadia-Beals (9 II, 21 III, 13 IV, 22 V). Tension wire þxation at the fracture site was augmented by screws in 39 fractures. The lateral malleolus was internally þxed in 39(60%) patients. In 48(74%) patients the þxation was extended to the calcaneus for 6 weeks. The metaphyseal defect (25 fractures, 38.5%) was treated by grafting in fourteen, acute shortening in six, and bone transport in þve fractures. Clinical and radiological results were evaluated. Results: Mean follow up was 3 years (1 to 10 years). On the basis of Ruedi-All-gower system, there was found negative correlation of the end result and þbular þxation in all the fractures types. However if Ovadia Beals system was used, þbular þxation was associated with better results in types II and III, but with inferior results in types IV and V. Conclusions: Ovadia Ð Beals classiþcation considers the metaphyseal defect and fracture comminution and should be chosen for the selection of the technique. In fractures with metaphyseal defect, þbular þxation does not allow acute shortening and makes bone transport more difþcult leading to poor results. Fibular plating is desirable for types II and III but it should be avoided or at least not preceded for types IV and V

To review the results of the treatment of pilon fracture with percutaneous internal fixation and extrarticular ring fixation in neutralization, twenty-two fractures in twenty-one patients were included in the study. The mean follow-up time was 5.3 years. Five fractures were classified Ruedi-Algower type I, six were Ruedi-Algower type II and eleven Ruedi-Algower type III. Six were open fractures (3 Gustilo type III) and there were 19 associated fibular fractures (five were internally fIxed). Thirteen fractures (60%) were associated with metaphysealdiaphyseal dissociation (MDD). The majority of fractures were high energy (18 out of 22). General health outcome was assessed with the use of the SF-36 and functional outcome was evaluated with AOFAS score and Bone’s criteria. The average AOFAS score for the study population was 79.4. The AOFAS scores decreased as the severity of the fracture increases and these differences were statistically significant between the Ruedi-Algower types I and III. The pilon fractures population scored lower in all SF-36 categories but mental health and energy and vitality when compared to an age matched population but statistically significant differences were only found in the categories of physical function and limitation due to health problems. 65% achieved excellent or good results according to Bone’s criteria. No significant differences were found in the union times in the MDD group (253 days) when compared to the fractures with no MDD (224 days), but this can be due to the high incidence of autograft in the MDD group (7 out of 13). All patients achieved full weight bearing at 6 weeks. Fourteen patients had superficial pin site infections (one needed screw removal) that settled with oral antibiotics. There was one case of non-union and two varus heels. Conclusion: Good results are achieved treating pilon fractures with minimal internal fixation and the Sheffield ring fixator in neutralization but quality of life and functional scores significantly worsen in the most severe Ruedi-Algower type III fractures

Fibular plating comprises a major component in the treatment of Pilon fractures with open reduction and internal fixation. However, its necessity when Pilon fractures are treated by hybrid fixation has been questioned. A retrospective clinical study with 65 high energy pilon fractures treated by circular fixators between 1996 and 2001 was undertaken, in order to clarify this technical detail. The mean age was 35 years (range 21 to 69 years). The fractures were classified according to the systems of Ruedi -Allgower (9 II, 56 III) and Ovadia-Beals (9 II, 21 III, 13 IV, 22 V). Hybrid fixation (tension wire fixation at the fracture site augmented by screws) was performed in 39 fractures. The lateral malleolus was internally fixed in 39(60%) patients. In 48(74%) patients the fixation was extended to the calcaneus for 6 weeks. The metaphyseal defect (25 fractures, 38.5%) was treated by grafting in fourteen, acute shortening in six, and bone transport in five fractures. Clinical and radiological results were evaluated. Mean follow up was 3 years (range 1 to 10 years). On the basis of Ruedi-Allgower system, there was a negative correlation between the end result and fibular fixation in all the fractures types (p< 0.001). However, if Ovadia Beals system was used, fibular fixation was associated with better results in type II and III, but with inferior results in type IV and V. We conclude that in fractures with metaphyseal defect, fibular fixation does not allow acute shortening and makes bone transport more difficult leading to poor results. Ovadia – Beals classification considers the metaphyseal defect and the fracture comminution and should be chosen for the selection of the technique. Fibular plating is desirable for types II and III but it should be avoided or at least not preceded for types IV and V

Background:. Pilon fractures are complex intra-articular fractures of the tibial plafond associated with significant short and long morbidity. Minimising surgical complications is essential. Methods:. Clinical and radiological outcomes in 49 patients with AO type 43B and 43C fractures were evaluated retrospectively. Definitive management depended on patient factors, soft tissue injury and fracture pattern. Results:. The majority of fractures (n=26, 53%) were C3 type. 9 fractures were open (18%), grade 3A or 3B. 34 patients (69%) were definitively managed with open reduction and internal fixation (ORIF) predominantly through an anterior approach. 15 (31%) had mini-open or percutaneous plafond reduction and external fixation. No medial plates were used. There were no deep infections. Complications occurred in 5 (10%) patients, all relating to metaphyseal delayed or non-union. At last review, 18 patients (36%) had radiographic evidence of post-traumatic arthritis. Discussion:. Surgeons treating pilon fractures should be familiar with external and internal fixation techniques in order to minimise surgical complications. An algorithm for treatment planning is suggested. Conclusion:. It is possible to achieve low surgical complication rates through careful management according to the nature of the fracture and patient characteristics. For plating, the antero-lateral distal tibial Peri-Loc plate is an effective and safe implant

Pilon fractures are associated to significant soft tissue injury, as well as soft tissue complications. The soft tissue on the medial side of the distal tibia is often involved, likely due to a lack of muscle investment. Medial approaches and medial plate application may well add to the soft tissue trauma. The objective of this study was to examine the relationship between medial plating and soft tissue complications in our center. This is a retrospective study based on a prospective database. Pilon cases treated with plate and screw fixation were identified between 2011 and 2014. Injury characteristics, patient demographics, and soft tissue complications were collected from chart review. Soft tissue complications recorded included any wound or skin problem, as well as patient complaints of hardware irritation leading to hardware removal. Logistic regression was employed. Independent variables for the model included medial plating, the presence of open fracture, smoking status and diagnosis of diabetes. Two models were created, one with the dependent variable as presence of any soft tissue complication, and the second model with the dependent variable as presence of a wound complication, which required surgical intervention. The study included 91 patients, 89 of whom had full data with an average follow up of 11.6 months (1–33 months). The incidence of soft tissue complications, including hardware irritation, was 26% (n=23), and 13% (n=12) required surgical treatment. Smoking status was the only predictor of soft tissue complications with an odds ratio of 3.6 (95%CI 1.2, 10.4; p=0.02), while controlling for other independent variables. The model explained 12% of the variation in soft tissue complications (Cox and Snell 0.119, p=0.028). In the second model, presence of a medial plate predicted soft tissue complications requiring surgical intervention with an odds ratio of 8.8 (95%CI 1.1, 73.7; p=0.045), while controlling for the other independent variables. The model explained 10% of the variation in soft tissue complications requiring surgical intervention (Cox and Snell 0.095, p=0.035). The use of a medial plate does not appear to correlate to general soft tissue complications in pilon fractures. Smoking status increased the odds of a soft tissue complication more than three fold. The use of medial plating did increase the odds of soft tissue complications that required surgical treatment almost nine fold. It appears medial plating is not related to soft tissue complications, however treating soft tissue compilations in the presence of a medial plate may require more invasive methods

The aim of this study was to document the outcome following either early or delayed fixation for complex (AO-OTA type 43.C) fractures of the tibial plafond. From our trauma database we identified all patients who sustained a complex intra-articular fracture of the distal tibia over an 11-year period. Demographic data, fracture classification, management, complications and subsequent surgeries were recorded. The primary outcome measure was the development of early complications following surgery. The secondary outcome measure was the long-term patient reported outcome. There were 102 type C pilon fractures in 99 patients with a mean age of 42yrs (16–86) and 75.5% (n=77) were male. 73 (71.6%) patients underwent primary open reduction internal fixation (ORIF), with 20 (19.6%) undergoing primary external fixation with delayed ORIF. 34 complications were recorded in 28 (27.5%) patients. There were 18 (17.6%) infections, with a deep wound infection in 9 (8.8%) patients and a superficial wound infection in 9 (8.8%). Risk factors for developing infection were multiple co-morbidities (p=0.008), an open fracture (p=0.008), and primary external fixation with delayed ORIF (p=0.023). At a mean of 6 years (0.3–13; n=53) post injury the mean FAOS score was 76.2 (0–100), the mean FADI score was 75.7 (0–100), and 72% (n=38) of patients were satisfied. This is the largest series in the literature documenting the outcome following fixation for type C tibial pilon fractures. Despite the severity of these injuries, we have demonstrated a satisfactory outcome using primary early fixation in the vast majority of cases

Ankle osteomyelitis after open pilon-fractures remain one of the most challenging scenarios. Ankle-fusion using an external frame is a classical option but in some cases of non-compliance patients could be not ideal. The purpose of this report was to evaluate our results using a new staged salvage protocol in cases where an external-frame arthrodesis is not recommended due to the issue of a non-compliance patient. During the first stage we resect all the infected tissues and an antibiotic-loaded cement spacer is used to obliterate the dead space, to reach some kind of stability and to achieve a high concentration of local antibiotic. A free or keystone flap is used if needed and a posterior splint is placed. After a course of targeted systemic antibiotics the second stage is schedule. During the second stage after the spacer removal, a self-made antibiotic coating retrograde hindfoot arthrodesis nail is used in order to achieve ankle fusion. We use a bone-substitute loaded with gentamicin (Cerament-G®) to fill the bone defects and to achieve high concentration of local gentamicin, to protect bone healing and to decrease the risk of relapse. We present four patients with ankle-osteomyelitis after open pilon fracture treated by such protocol. We receive all patients > 6 months after the initial fracture. In all cases type III-B open pilon fracture was the initial injury. All the patients presented psychological disturbances and the possibility of perform an external frame reconstruction was considered not indicated. At presentation, all patients have compromised skin around the distal tibia area. According to the Cierny/Mader osteomyelitis classification all patients were Type IV-Blocal. Compromises soft tissues were treated with an ALT free flap in two cases and with a Keystone flap in two cases. 10 mL paste of Cerament-G® was used in each case with a single case where a white-draining event was present without further complication. Tibiotalocalcaneal fusion was achieved after 4 months in all cases. At average of 7 months of follow-up, none of the four fused ankles has required further surgery and no infection relapse was observed. The use of this salvage treatment protocol has proven safe and useful for such difficult problem in these difficult patients, with a relatively low associated complication rate. Cerament-G® is a useful tool in order to fill all the bone voids, promote bone healing and simultaneously to protect the surgical area due to the high local concentration of gentamicin

Introduction. The treatment of posterior malleolar fractures is developing. Mason and Molloy (Foot Ankle Int. 2017 Nov;38(11):1229-1235) identified only 49% of posterior malleolar rotational pilon type fractures had syndesmotic instabilities. This was against general thinking that fixation of such a fragment would stabilize the syndesmosis. Methods. We examined 10 cadaveric lower limbs that had been preserved for dissection at the Human Anatomy and Resource Centre at Liverpool University in a solution of formaldehyde. The lower limbs were carefully dissected to identify the ligamentous structures on the posterior aspect of the ankle. To compare the size to the rotational pilon posterior malleolar fracture (Mason and Molloy 2A and B) we gathered information from our posterior malleolar fracture database. 3D CT imaging was analysed using our department PACS system. Results. The PITFL insertion on the posterior aspect of the tibia is very large. The average size of insertion was 54.9×47.1mm across the posterior aspect of the tibia. Medially the PITFL blends into the sheath of tibialis posterior and laterally into the peroneal tendon sheath. 78 posterior lateral and 35 posterior medial fragments were measured. On average, the lateral to medial size of the posteromalleolar fragment was 24.5mm in the posterolateral fragment, and 43mm if there is a posteromedial fragment present also. The average distal to proximal size of the posterolateral fragment was 24.5mm and 18.5mm for the posteromedial fragment. Conclusion. The PITFL insertion on the tibia is broad. In comparison to the average size of the posterior malleolar fragments, the PITFL insertion is significantly bigger. Therefore, for a posterior malleolar fracture to cause posterior syndesmotic instability, a ligamentous injury will also have to occur. This explains the finding by Mason and Molloy that only 49% of type 2 injuries had a syndesmotic injury on testing

The October 2014 Foot & Ankle Roundup360 looks at: multilayer compression bandaging superior for post-traumatic ankle oedema; compression stockings for ankle fractures; weight bearing ok in Achilles tendon ruptures; MRI findings can predict ankle sprain symptoms; salvage for malreduced ankle fractures; locking fibular plates are more expensive; is fixation better early or late in pilon fractures?; and calcaneal fracture fixation not for subtalar arthropathy

A series of 49 pilon fractures in a tertiary referral centre treated definitively with open reduction and internal fixation have been assessed examining the complications associated with such injuries. A retrospective analysis of casenotes, radiographs and computerised tomographs over a seven year period from 1999–2006 was performed. Infection was the most common post operative problem. There were 7 cases of superficial infection. There was a single case of deep infection requiring intravenous antibiotics and removal of metalwork. Other notable complications were those of secondary osteoarthritis (three cases) and malunion (one case). The key finding of this paper is the 2% incidence of deep infection following the direct operative approach to these fractures. The traditional operative approach to such injuries (initially advocated by Ruedi and All-gower) consisted of extensive soft tissue dissection to gain access to the distal tibia. Our preferred method is to gain access to via the “direct approach” which involves direct access to the fracture site with minimal disturbance of the soft tissue envelope. We therefore believe open reduction and internal fixation of pilon fractures via the direct approach to be an excellent technique in the treatment of such injuries

Introduction:. In this cohort study, we present comprehensive injury specific and surgical outcome data from one of the largest reported series of distal tibial pilon fractures, treated in our tertiary referral centre. Methods:. A series of 76 pilon fractures were retrospectively reviewed from case notes, plain radiographs and computed tomography (CT) imaging. Patient demographics, injury and fracture patterns, methods and timing of fixation and clinical and radiological outcomes were assessed over a mean follow up period of 8.6 months (range 2–30). Results:. Definitive fixation was most commonly performed through an open technique with plate fixation. CT imaging was used to plan the most direct approach to access the fracture fragments. The majority of cases were classified as AO/OTA 43.C3. When definitive open fixation for closed fracture was performed within 48 hours, the rate of deep infection or wound complication was 0%. When performed on day 3–5, the deep infection rate was 0% but the superficial wound complication rate was 23.5%. From day six onwards, the deep infection rate was 4% and the superficial wound complication rate was 8%. The rate of wound complications after double plate fixation of the tibia using two separate incisions was 23.1%, compared to 11.7% after single incision and plating. The rate of non-union was 9.7%. Symptomatic post-traumatic arthritis requiring orthopaedic management occurred in 9.9%. Further surgery was required in 27.8% of all patients. Conclusion:. Outcomes from our unit compare favourably with those from large trauma centres worldwide. Our study supports the use of early definitive fixation, within 48 hours, to achieve low rates of wound complications. We support an “unsafe window” for definitive fixation of three to five days post injury due to the high rate of wound complications. The likelihood of developing post-traumatic arthritis and of requiring further surgery is high

Introduction: High energy tibial pilon fractures are usually associated with a significant bone loss in the metaphyseal area of the tibia. This study evaluates three different treatment options for the management of the metaphyseal bone loss. Materials and Methods: Betwwen 1996 and 2007, 85 high energy pilon fractures- Ovadia Beals type IV: 39 and V: 46- were treated and reviewed in our institution. Twenty four fractures were open, and fifty one closed fractures had soft tissue lesion grade1 or 2 according to Tscherne classification. To restore the bone continuity in tibia metaphyseal area bone graft substitutes were used in 53 fractures, acute shortening and proximal lengthening in 18 fractures and bone transport in 14 fractures. Evaluation was carried out according to the Ovadia-Beals evaluation system. Results: The mean average follow up was 6 years. Thirty seven fractures (70%) treated with bone graft substitutes achieved an excellent or good result. Eleven fractures (61%) treated with proximal tibia lengthening achieved an excellent or good result, whereas only eight fractures (57%) treated with bone transport achieved an excellent or good. Bone infection was recorded in 6 fractures, all in the group of the patients treated with bone graft substitutes. Conclusion: The management of the metaphyseal bone loss in the high energy tibial pilon fractures is a basic priority to achieve a satisfactory result. Hybrid external fixation with the use of bone graft substitutes seems to be a more suitable technique to these devastating injuries. However bone infection remains a major concern for these devastating injuries

Axial loading of the foot/ankle complex is an important injury mechanism in vehicular trauma, responsible for severe injuries such as calcaneus, talus and tibial pilon fractures. Axial loading may be applied to the leg externally, by the toepan and/or pedals, as well as internally by active muscle tension applied through the Achilles tendon during pre-impact bracing. In order to evaluate the effect of active muscle tension on the injury-tolerance of the foot/ankle complex, axial impact tests were performed on isolated lower legs, with and without experimentally stimulated muscle tension applied through the Achilles’ tendon. Acoustic emission was used to determine the exact time of fracture during the tests. The primary fracture mode was calcaneal fracture in both groups, but tibial pilon fractures occurred more frequently with the addition of Achilles tension. A linear regression model was developed that describes the expected axial loading injury tolerance of the foot/ankle complex in terms of specimen age, gender, mass and level of Achilles tension

Purpose: The purpose of this study was to review our results in patients with pilon fractures treated with ORIF in which surgical planning involved multiple skin incisions, ensuring that the distance incisions overlapped was less than the distance between them. We hypothesized that soft-tissue complications would be minimal despite incisions placed < 7-cm apart. Method: A retrospective chart review identified 37 pilon fractures in 32 patients treated by three orthopedic traumatologists at The Ottawa Hospital between August 2000 and February 2007. Follow-up included measurements of incision placement and functional outcome measures. Results: There were nine OTA type B and 28 OTA type C fractures; 28 were closed and nine were open. The mean age was 46.5 ±14.5 years, and average follow-up was 3.2 ±1.7 years. Of the patients reviewed, the average number of incisions was 3.7 ±1.1. The average overlap between incisions was 4.6-cm ±1.9 and the average skin bridge between incisions was 5.9-cm ±1.9, with 80% of the skin bridges < 7-cm. Average ROM was 4.3° ±7.1 dorsiflexion and 39.1° ±11.6 plantarflexion. The mean AMA lower extremity impairment score was 18.9% ±12.4, and mean SIP ambulation score was 9.6 ±8.8. Complications included two superficial infections, one deep infection, and three non-unions. There were no cases of wound dehiscence or necrosis, or cases requiring revision soft-tissue coverage. These outcomes were comparable to recent reports with similar injuries. Conclusion: With careful planning and good soft-tissue management, incisions can be placed to maximize articular exposure based on fracture lines. It does not appear that the dogma of keeping incisions > 7-cm apart must be followed in most cases. Prudent surgical timing and meticulous soft-tissue handling can allow for multiple incisions to be placed as necessary for fracture reduction and optimal fixation while maintaining a low rate of complications

Aims: Ankle fractures are injuries with intraarticular imapct. Therefore the treatment must be very precise (meticilous). Numerous and heterogenous factors inßuence the late results in both conservativelly and operatively treated ankle fractures. So the aim of the study was to determine the list of prognosticaly and statistically signiþcant factors in the ankle fractures. Material and methods: 504 patients who were treated for ankle fractures for 5 year period were followed for 3 to 10 years. All fractures were clasiþed according to Lauge Hansen clasiþcation. Conservative treatment consists of reduction and plaster imobilisation for 5–7 weeks, while in operative treated patients internal þxation were performed for most fractures while in pronation dorsißexion- pilon fractures minimally internal þxation in combination with dinamical external þxation was done. Results: pronation-eversion (grade 2) fractures has the same result in both kinds of treatment, while pronation Ðeversion and pronation fractures show better results in operatively treated patients and pilon fractures with dynimical external þxation. Conclusion: the displaced fractures shoud be anatomically reduced, either by closed or open. The most decisive factors inßuencing the late result in ankle fractures are: type of fracture, age, anatomical reduction, talocrural angle, size of posterior fragment, lateral shortening and condition of soft tissue

Introduction: The Staffordshire Orthopaedic Reduction Machine (STORM) was developed to assist in the reduction of tibial shaft fractures prior to the application of an external fixator. Its use has now been extended to fractures of the tibial plateau and plafond, where it has been utilised to gain and hold a good reduction prior to the application of various internal and external fixation techniques. Methods: The STORM was used sterile within the operative field on a standard radiolucent operating table. It was applied with two tensioned 2 mm wires: the distal through the calcaneum; the proximal through the proximal tibia for shaft and pilon fractures, and through the distal femur for plateau fractures. Controlled traction was applied through these two wires. Torsion was independently corrected and locked. Translation and angulation was corrected using two translation arms each applied to the tibia with a single unicortical screw. The STORM was removed at the end of each operation. Results: The STORM was used in 241 cases. Pilon (n=42): bridging hinge 23 (t [mean operation time in minutes]=102.9), percutaneous plate 10 (t=131.4), ring fixator 5 (t=140), screws and fibula plate 3 (t=77), other 2. Plateau (n=23): ring fixator 11 (t=129.7), LISS plate 8 (t=98.6 mins), monolateral Garches fixator 3 (t=64.4), screws only 1 (t=15). Shaft (n=176): monolateral fixator 138 (t=69.1), ring fixator 37 (t=131.2), nail 1 (t=65). Ilizarov rings up to 200 mm were accommodated. Discussion: The STORM is a safe device for reliable reduction of tibial plateau, shaft and pilon fractures which allows good access for internal or external fixation. No significant complications attributable to the use of the current design of the STORM were encountered

Purpose: Fractures of the distal tibia are high energy fractures, associated with marked soft-tissue trauma. Management of these fractures is challenging. The purpose of this study is to present our experience on the treatment of these fractures using hybrid external fixation, with or without open reduction and minimal internal fixation of the fibular fracture. Patients and Methods: Forty eight patients with a distal tibial fracture were admitted to the authors’ institution since 2005. There were 33 men and 15 women. According to AO there were 24 A, 10 B and 14 C fractures. The mean age of the patients was 45.6 years. Eight patients had an open pilon fracture; according to the Gustilo classification, 1 patient had a grade I, 5 patients had a grade II, and 2 patients had a grade III open fracture. In all patients, the pilon fracture was treated using hybrid external fixation; in 18 patients, open reduction and minimal internal fixation of the fibular fracture using plate and screws was also done. Results: Mean follow-up was 14 months (range, 9 to 36 months). In all patients, the mean duration of the application of the external fixation was 2.85 months, followed by the application of a below-knee cast. In 42 patients, radiographic evidence of union was observed at 3,6 months (range, 3 to 9 months). Time for union was different between patients with closed and grade I open fractures compared to patients with grade II and grade III open fractures (union at 3.5 and 6 months, respectively). There were 5 non-unions (10,4%) with 3 of them septic (6,25%). All three deep infections were low grade and occurred in open fractures.Delayed union was observed in 3 patients; in these patients, solid union of the fracture was observed at 7 months (range, 6 to 9 months). Pin track infection was observed in 7 patients (14.6%). Conclusion: Based on the present study, hybrid external is associated with satisfactory results for the management of distal tibial fractures with acceptable complications

Aims: To determine the results of Òbiologic þxationÒ with a minimally invasive plating technique using a newly designed low proþle ÒScallopÒ plate in the treatment of pilon fractures. Methods: 17 patients were treated between 1999 and 2001 for a tibial plafond with a newly designed ultra-slim plate. Eleven (65%) were high-energy injuries, two were open. Staged open reduction and þxation of the þbular fracture and application of an External Fixator was performed in 12 cases. As soon as the soft tissues and swelling allowed, the articular surface was reconstructed and anatomically reduced, if necessary through an small incision, and the articular block was þxed to the diaphysis using a medially placed, percutaneously introduced ßat Scallop plate. Time to healing and complications were evaluated. Quality of the results and outcome were graded using the Ankle-Hindfoot-Scale. Results: All patients went on to bony union at an average time of 14.1 weeks. There were no plate failures or loss of þxation/ reduction. Two superþcial wound-healing problems resolved with local wound care. At an average FU of 17 months eight patients (47%) had an excellent, seven (41%) a fair and two (12%) a poor result. The average AHS was 86.1. Conclusions: Based on these initial results, it appears that a minimally invasive surgical technique using a new low proþle plate can decrease soft tissue problems while leading to fracture healing and obtaining results comparable with other more recent series. We believe that this new ÒScallop PlateÒ is appropriate for the treatment of pilon fractures and should be used in conjunction with a staged procedure in the acute trauma setting

Introduction: Locking plate technology for fixation of periarticular fractures has been adopted widely since its development. Distal tibial/pilon fractures represent one of the major indications of this method of fixation. The recent development of polyaxial locking systems has offered more versatility to the surgeon. Patients and Methods: In this cohort prospective study we present our early experience of a new polyaxial locked plating system in the treatment of complex ankle and distal tibial fractures (anatomic locked plating systems– ALPS, DePuy). Demographic, mechanism of injury, AO-OTA classification, surgical procedure, postoperative course, complications, rehabilitation scheme, clinical and radiological healing as well as functional outcome (SF-36, Olerud & Molander Ankle Score, AOFAS Ankle-Hindfoot Scale, VAS pain score) were all recorded over a minimum follow-up period of 9 months. Results: Between July 2008 and July 2009, there were 21 patients with complex ankle and distal tibial fractures who were treated with this method of fixation. There were 16 males and 5 females. The mean age was 42.9 years (16–90). All female patients were over 60 years. The majority of these injuries were related to falls or RTAs (11 and 8 cases respectively). The mean time from injury to operation was 5 days (range 1 to 14 days), and in the majority of these cases a temporary bridging external fixator was applied (in 17/21 cases). All injuries were closed fractures. There were 11 patients with 43-A, 5 with 43-B, 5 with 43-C. Fractures were treated with a choice of medial ALPS tibial plate (12 patients), anterolateral ALPS tibial plate (9 patients). There were 8 associated distal fibular fractures, which were also fixed with a plate. The mean length of stay was 8 days (range 4 to 27 days). One patient had to be converted to a circular external fixator due to local deep sepsis, while two other patients had local wound healing problems managed without implant removal. The overall healing rate was over 95%, with one case of non-union at 9 months. Fifteen of them have returned to their work, while the recorded functional scores at the last follow-up visit were good in the majority. Conclusions: The overall clinical and functional outcome of this cohort of patients over the short-term follow-up was recorded to be comparable to existing similar case series of open reduction internal fixation of pilon fractures. The surgical advantages of the new system lie in its versatility, and short learning curve

Introduction: Pilon fractures are severe injuries of the distal tibia usually characterised by severe soft tissue “hit” in addition to the underlying fracture. Historically, plating techniques have led to a significant rate of serious complications. This study describes our early experience treating such injuries by the Ilizarov Method. Methods: 30 patients were prospectively identified and followed up beyond frame removal clinically and by case note review. Fractures classified according to AO. Bony union evaluated radiologically and clinically – remodelling of bone trabeculae on two radiographs and ability to weight bear without discomfort/walking aids on a dynamised frame. Results:. Mean age 45.3 years, male: female = 26:4. Seven fractures were Grade 3 open. Patients were grouped as follows:. 43-A .1/.2/.3 = 1/2/2. 43-B .1/.2/.3 = 1/0/4. 43-C .1/.2/.3 = 3/4/13. Two patients with 43-C.3 fracture had additional corticotomy for bone loss. Twenty-nine pilons united. Overall mean time to union was 20 weeks. Times to union (weeks):. Group 43-A: - median = 20, mean = 21. Group 43-B: - median = 11, mean = 12. Group 43-C: -median = 20, mean = 21. Group 43-C.3: -median = 20, mean = 21. 24 patients had no major complications. One Grade 3B open 43-C.3 fracture had deep sepsis prior to transfer to our unit which could not be eradicated – this led to transtibial amputation. Two patients had valgus mal-union and One had stiff nonunion requiring a second frame. Eleven patients experienced superficial pinsite infection that resolved with oral antibiotic therapy. Two deep pinsite infections were eradicated by overdrilling. Conclusion: The Ilizarov method offers safe and reliable healing for distal tibial pilon fractures in mean 20 weeks, with low levels of serious complications despite the severity of the initial injuries

There is an ongoing revolution in the use of data within orthopaedics and medicine in general, with an imperative for surgeons to be involved from the bottom up and better define the data collection culture. The use of registries plays a major role in the development of “big data” in orthopaedics. There are multiple examples that are already set up and running, both those inspired and set up by clinicians or those where the main stakeholders may lay people, with some input from clinicians. The British Limb Reconstruction society is no exception, with registries for lengthening nails and pilon fractures due to roll out imminently. The BLRS has tasked this years BOA clinical leadership fellow to investigate the current state of registries among the specialist orthopaedic societies. In particular, comparison of the already well established registries and national audits with the development of registry projects in the smaller societies. The issues of funding, consent, infrastructure and governance each infer particular challenges when translating the methods of the larger registries to the needs and resources of a smaller group. We have aimed to consider these challenges in relation to the set-up of the BLRS registries in order to better understand the potential future pitfalls and opportunities

Purpose: We report a series of 50 pilon fractures treated by osteosynthesis and report outcome at minimum seven years. Material and methods: The series included 28 men and 22 women, mean age 44 years. Thirty-one patients were fall victims. The AO classification was type B (n=24) and type C (n=26). According to the De Lestang classification there were 12 simple fractures and 38 complex fractures (including 26 complete fractures) Sixteen fractures were open and 39 were associated with a fracture of the lateral malleolus. Most of the fixations were achieved via an anterolateral approach (n=22) using a prebent plate, or via a medial approach using a clover-leaf plate. A cancellous graft was used in seven cases. The Kitaoka classification was established at last follow-up. Results: The radiographic work up included a lateral view and an anteroposterior view with moderate medial rotation. Mean follow-up was fourteen years. There were ten secondary displacements. Late complications were: non-union (n=14, including 10 cases requiring revision for arthrodesis), reflex dystrophy (n=6), deformed callus formation requiring revision, and one case of amputation after infection. At last follow-up, 33 ankles were painful (including 13 permanently painful ankles). Twenty-four patients had a residual limp (13 permanent) limiting walking distance in half of them. The talocrural joint motion was normal in 20 patients and the subtalar joint was normal in 24. Twenty-three patients resumed their former activities. For patients with sports activities, 64% resumed activities at the same level. The Kitaoka score was 79 points at last follow-up with outcome scored good in 70%, fair in 16% and poor in 14%. Excepting the patients who had secondary arthrodesis, 24 patients developed secondary osteoarthritis (including ten stage 2 and 3). Discussion: Good outcome depends on the intraoperative reduction, both at the epiphyseal level (for complete fractures) and the metaphyseal level. This reduction must be maintained over time with a good fixation rigid enough to avoid secondary displacement which is a cause of callus deformation. The severity and complexity of the initial fracture constitute the main factors affecting outcome. In our opinion, computed tomography provides the best means of establishing the therapeutic indications. Pilon fractures remain a difficult challenge in orthopaedic surgery. Perfect reduction is the best guarantee of good outcome

Aim. The incidence of deep infections after internal fixation of ankle and lower leg fractures is estimated 1 to 2%. Hindfoot arthrodesis by retrograde intramedullary nailing (IMN) is a potential alternative to external fixation for post-infectious ankle destruction. The aim of this study was to evaluate the clinical results, complications and effects of soft tissue management with this treatment modality. Method. This is a single-center retrospective review of routine hospital data from 21 patients (15 men, 6 women, median age 65 [range, 21 to 87] years) undergoing IMN arthrodesis of the hindfoot for post-traumatic infections between January 1st, 2012 and March 15, 2018. We observed four bimalleolar, eight trimalleolar, three pilon fractures, and six distal lower leg fractures. Six and three patients had sustained second- and third degree open fractures, respectively. Early- and late-onset surgical infections were observed in 8 and 13 cases. Four participants had diabetes mellitus, two arterial occlusive disease, and four had both. Six patients were smokers. Results. Intraoperative cultures before implanting the nail revealed staphylococcus aureus in 12, staphylococcus epidermidis in five, and enterococcus faecalis in eight cases. After a median follow-up of 21 months, infection was considered cured in 19 / 21 subjects (90%, 95% confidence interval 70 – 99%). Soft tissue comminution required coverage with a suralis flap in five patients, and with a latissimus dorsi flap in another three. Mesh graft was necessary in 8 / 21 reconstructions. Conclusions. Tibiotalocalcaneal fusion by IMN is an effective salvage procedure for post-traumatic ankle infections. Arthrodesis and definitive wound closure or plastic flap coverage can be performed as single-stage surgery. By resecting the prominent distal fibula, lateral soft tissue defects can be managed more easily. The small sample size prohibited a more detailed analysis of exposure variables, but 8 / 13 patients in this cohort had at least one known risk factor for infection and prolonged healing

Pilon fractures present a unique challenge to the patient and orthopaedic surgeon. Care for the soft tissue envelope is as important as management of this articular fracture. Assessment of the degree of energy causing the fracture and careful planning of the joint reconstruction will lead to acceptable results in most cases. Forty-five patients (AO-ASIF classification) treated between 2003 and 2008 were examined clinically and radiologically at an average of 24 months after injury. The patients were treated in three different ways: primary internal fixation with a plate following, which was reserved for patients with closed fractures without severe soft tissue trauma; one-stage minimally invasive osteosynthesis for reconstruction of the articular surface with long-term transarticular external fixation of the ankle for at least eight weeks and hybrid external fixation. Objective evaluation criteria were infection rate, pseudarthrosis, amount of posttraumatic arthritis, range of ankle movement. In 65% of all pilon tibial fractures we observed an uncomplicated course of healing. Early complications were mainly soft tissue infections, whereas we found pseudarthrosis to be the most frequent late complication. The complication rate depends mainly on the type of fracture, the soft tissue damage and the type of treatment. In the case of low-grade soft tissue damage, good to excellent results were accomplished. In the case of higher-grade soft tissue damage, the problem of soft tissue coverage and reconstruction of the joint surface could be solved with good results by the hybrid external fixation. Herewith it is important to use limited open reduction of displaced fragments and fixation by cannulated screws and K-wires

Care of complex and open fractures may provide better results if undertaken in larger units, typically Major Trauma Centres (MTCs) or Orthoplastic units. Some ‘complex injuries’ may still be admitted to units lacking specialist services potentially delaying definitive treatment. The aim of this study was to analyse the referral pattern for acute inpatient transfer in an adult limb reconstruction unit for one calendar year. Prospectively collected data from an electronic database for 2016 was reviewed. All records were evaluated for, diagnosis, time from injury to referral, nature of initial treatment, time to transfer, details of definitive surgery, and time to repatriation. There were 91 formal electronic referrals, 84 of which considered appropriate for inpatient transfer. 74 were for fresh complex fractures, including 22 pilon fractures and 23 bicondylar tibial fractures. Median delay to request transfers for acute trauma was 3 days (0d-19d), delay from referral to transfer was 8.5 days (1d-31d) and delay from date of injury to definitive surgery was 13 days (1d-52d). 9 patients with Grade 3 open fractures and had primary debridement at the referring institution with a median delay to definitive orthoplastic surgery of 9 days (5d-20d). Only 17 of 61 per-articular fractures had spanning external fixation at the referring institution. Delay to repatriation was 8 days (0d–72d). This study demonstrates organisational failures in acute orthopaedic care: open fractures not being primarily treated in orthoplastic centres or MTCs, delays in transfers due to bed-blocks, and significant delays in repatriation. It also demonstrates scope for improvement in clinical practice, and in particular, the need to reinforce the advantages of spanning external fixation of periarticular fractures. Our data serves to highlight continuing problems in delivery of acute fracture care, despite widely publicised recent national guidelines

Decreased ankle dorsiflexion is common after injury and may result in patient complaints of stiffness and subsequent injury. The weight-bearing lunge test (WBLT) is a simple clinical measure of dorsiflexion. Previous study has defined a 2.0cm side-to-side discrepancy in WBLT as likely significant. With review of current literature, ankle stiffness is a concept largely undefined; we aim to relate patient complaints of stiffness to WBLT. This was a population-based inception cohort with longitudinal follow-up. Patients between ages 18–65 receiving surgical fixation for ankle fracture were screened. Pilon/plafond fractures, bilateral injuries, or polytrauma were excluded. At 6-weeks, 6-months, and 1-year WBLT was measured along with non-weight-bearing goniometry; and an Olerud-Molander ankle score completed. 155 patients were recruited (90 female, 65 male; mean age 42, range 20–67). 47% of injuries were unimalleolar, 17% bimalleolar, and 36% trimalleolar; 35% received syndesmotic fixation. 89% of patients reported feeling stiff at 6-weeks, 82% at 6-months, and 74% at 1-year. 98% of patients had ≥2.0cm discrepancy of WBLT at 6-weeks, 78% at 6-months, and 72% at 1-year. Different thresholds of WBLT (larger discrepancy or absolute negative measurement) had worse correlation with patient reported stiffness. Our population had high incidence of stiffness at 1-year. The proportion of patients complaining of stiffness after ankle fracture was similar to that measured with ≥2.0cm discrepancy of WBLT. This is the first study that we are aware of that relates the WBLT and the previously reported threshold of 2.0cm to stiffness. This measurement may give clinicians a better objective idea regarding patient perception of a “stiff” ankle. Reducing side to side discrepancy in range of motion should be considered in rehabilitation rather than total range of motion

Background:. The aim of this study was to review the surgical complications and clinical outcomes of patients with Pilon fractures treated with Ilizarov frames. Methods:. Data collected included surgical complications, grade of initial injury using the Ruedi-Allgower classification and quality of reduction according to the Teeny and Wiss criteria. Outcome scores were collected retrospectively using the Foot and Ankle Disability Index (FADI). Results:. A total of 97 consecutive patients were identified. All patients were treated with indirect reduction by capsuloligamentotaxis and stabilisation using an ankle-spanning Ilizarov external fixator. The mean time to union was 6 months. Data was available for 70 patients. 35 patients developed a pin site infection. There were no cases of osteomyelitis. 4 patients developed a DVT and 1 patient a PE, 4 patients required ankle fusions. Quality of reduction according to the criteria of Teeny and Wiss was anatomic in 40 patients, good in 23 patients, fair in 6 patients, poor in 3 patients. Conclusion:. This is one of the larger series of Pilon factures on literature review. Ilizarov frame fixation achieves stable reduction of the fractured fragments without additional trauma to soft tissues with minimal complications and good functional results

Musculoskeletal diseases are having a growing impact worldwide. It is therefore crucial to have an evidence base to most effectively and efficiently implement future health services across different healthcare systems. International trials are an opportunity to address these challenges and have many potential benefits. They are, however, complex to set up and deliver, which may impact on the efficient and timely delivery of a project. There are a number of models of how international trials are currently being delivered across a range of orthopaedic patient populations, which are discussed here. The examples given highlight that the key to overcoming these challenges is the development of trusted and equal partnerships with collaborators in each country. International trials have the potential to address a global burden of disease, and in turn optimize the benefit to patients in the collaborating countries and those with similar health services and care systems.

Aims

Triplane ankle fractures are complex injuries typically occurring in children aged between 12 and 15 years. Classic teaching that closure of the physis dictates the overall fracture pattern, based on studies in the 1960s, has not been challenged. The aim of this paper is to analyze whether these injuries correlate with the advancing closure of the physis with age.

The February 2024 Trauma Roundup³⁶⁰ looks at: Posterior malleolus fractures: what about medium-sized fragments?; Acute or delayed total hip arthroplasty after acetabular fracture fixation?; Intrawound antibiotics reduce the risk of deep infections in fracture fixation; Does the VANCO trial represent real world patients?; Can a restrictive transfusion protocol be effective beyond initial resuscitation?; What risk factors result in avascular necrosis of the talus?; Pre-existing anxiety and mood disorders have a role to play in complex regional pain syndrome; Three- and four-part proximal humeral fractures at ten years.

Most of current literatures advise on thromboprophylaxis with injectable LMWH for trauma patients. Injectable anticoagulants have got inherent problems of pain, bruising and difficulty in administering the drug, which leads to low compliance. Clexane is derived from a pig's intestinal mucosa, hence could be objectionable to certain proportion of patients because of their religious beliefs. Oral anticoagulants have been used as thromboprophylactic agents in hip and knee arthroplasty. However there is not enough literature supporting their use as thromboprophylactic agent in ambulatory trauma patients with ankle fracture being managed non-operatively as out-patient. This study looks into the efficacy of oral anticoagulant in preventing VTE in ambulatory trauma patients requiring temporary lower limb immobilisation for management of ankle fracture. The end point of this study was symptomatic deep vein thrombosis (either proximal or distal) and pulmonary embolism. Routine assessment with a VTE assessment risk proforma for all patients with temporary lower limb immobilisation following lower limb injury requiring plaster cast is done in the fracture clinic at this university hospital. These patients are categorised as low or high risk for a venous thromboembolic event depending on their risk factor and accordingly started on prophylactic dose of oral anticoagulant (Rivaroxaban - Factor Xa inhibitor). Before the therapy is started these patients have a routing blood check, which includes a full blood count and urea and electrolyte. Therapy is continued for the duration of immobilisation. Bleeding risk assessment is done using a proforma based on NICE guideline CG92. If there is any concern specialist haematologist advice is sought. A total of 200 consecutive patients who presented to the fracture clinic with ankle fracture, which was managed in plaster cast non-operatively, were included in this study. They were followed up for three months following injury. This was done by checking these patients’ radiology report including ultrasound and CT pulmonary scan (CTPA) test on hospital's electronic system. Fracture of the lateral malleolus which include Weber-A, Weber-B and Weber-C fractures were included in the study. Also included were bimalleolar fractures and isolated medial malleolus fractures. Complex pilon fractures, polytrauma and paediatric patients were excluded from the study. Only one case of plaster associated isolated distal deep vein (soleal vein) thrombosis was reported in this patient subgroup. There was no incidence of proximal deep vein thrombosis or pulmonary embolism. No significant bleeding event was reported. Injectable low molecular weight heparin (LMWH) rather than oral anticoagulant has been recommended by most of the studies and guidelines as main thromboprophylactic agent for lower limb trauma patients

We treated 60 patients with type III Pilon fractures (Ruedi and Allgower Classification) between 1996 and 2005. The fractures were distracted and then fixed with an Ilizarov circular ring fixator, without the use of open surgery. No internal fixation was used for the tibia or fibula. No bone grafting was performed. The average time from injury to frame application was four days. The patient stayed ib frame for a mean time of 15 weeks. No second operative procedure was needed. All cases united in good alignment. The patients were reviewed from ten years to nine months after frame removal. Four separate evaluations were performed (functional, objective, radiological and an SF-36). The function and the range of movement were better than the radiological assessment suggested. This method of treatment gives better results with fewer complications than open surgery with internal fixation

A series of 76 distal tibial pilon fractures treated with surgical fixation were retrospectively reviewed from case notes, plain radiographs and CT imaging. Patient demographics, injury and fracture patterns, methods and timing of fixation and clinical and radiological outcomes were assessed over a mean follow up period of 8.6 months (range 2–30). Definitive fixation was most commonly performed through an open technique (71 cases) with plate fixation. CT imaging was used to plan the most direct approach to access the fracture fragments. Single or double incision techniques were used to access the tibia, with fixation of the fibular performed when necessary. Superficial infection occurred in 5 cases (6.9%) and deep infection in 2 (2.8%). Aseptic wound breakdown occurred in 5 cases (6.9%). The rate of wound breakdown after three-incision technique was 37.5%. There were 10 cases of non-union (13.9%) and 8 of mal-union (10.5%). Post-traumatic arthritis was present on the most recent x ray in 17 cases (23.4%). Further surgery was required in 20 cases (27.8%), most commonly for metalwork related problems and also for treatment of non-union, post-traumatic arthritis and infection. This review gives comprehensive injury specific and surgical outcome data from one of the largest reported series of these complex and problematic injuries

Introduction:. The Best Practice Tariff (BPT) for hip fractures was introduced in April 2010 to promote a number of quality markers, including surgery within 36 hours. We conducted an audit to see whether the introduction of the BPT has had an inadvertent adverse effect on delay to fixation of unstable ankle fractures. Method:. We compared the delay to surgery for 50 consecutive patients with unstable ankle fractures in the 2009 financial year with another 50 patients treated in the 2011 financial year, ie one year after the introduction of the BPT. There were no other changes in service in our department in this period. All radiographs were reviewed and classified using the Lauge-Hansen system by 2 surgeons. Excel was used for data analysis using unpaired T-Test and chi-squared test to assess significance. Results:. 2 patients with pilon fractures were excluded from each group. Demographics and fracture pattern between the remaining 48 patients in each group were similar. The mean delay to surgery before BPT was 2.2 days compared with 3.8 days after its introduction (p = 0.01). 7 patients waited more than 5 days for surgery before BPT compared with 17 patients after its introduction (p < 0.001). There was 1 manipulation under anaesthetic (MUA) before BPT and 8 MUAs in 7 patients after its introduction (p < 0.001). Conclusion:. There is a significant association between the introduction of BPT for hip fractures and an increase in the delay to surgery for patients with unstable ankle fractures by an average of 1.6 days. More patients waited more than 5 days for surgery and there were more MUAs. We postulate that in a resource-limited NHS, prioritizing one patient group inevitably disadvantages others. Orthopaedic trauma services must adapt to national guidance to ensure all patients are treated in a timely fashion

Purpose of the study:. Is circular external fixation a safe and effective method of managing closed distal third tibia fractures. These fractures are conventionally treated with plaster casts, intramedullary nails or plate fixation. These treatment modalities have complication rates in the literature of up to 16% malunion, 12% non-union, and 17% deep infections. Description and Methods:. Retrospective review of 18 patients with closed distal third tibia fractures, with or without extension into the ankle joint, treated with circular fixator systems and minimal percutaneous internal fixation of the intra-articular fragment if required. Patients were followed up for time to union, malunion incidence as well as incidence of pin tract and deep infection. Distal third fractures which were extra articular or with simple intra articular extension were included. (AO 43 A, B1, C1, C2 + AO 42 in distal third) Patients with pilon fractures (AO 43 B2, B3 and C3) were excluded. Summary of results:. The average time to union in these patients was 16 weeks (11–33 weeks). The non-union rate was 11.1% in comparison to 12% with conventional treatment. The malunion rate was 0% compared to 16% with conventional treatment. The incidence of pin tract infection was 16.6%, but no deep infections were noted, whilst conventional treatment shows deep infection in up to 17%. Conclusion:. Circular external fixation is a safe and efficient option in the treatment of distal tibia fractures. The incidence of complications is significantly reduced in comparison to conventional treatment

Introduction. The optimal treatment of high-energy tibia fractures remains controversial. The role of external fixators has been shown to be crucial. This study aimed to compare the effectiveness of using either Taylor Spatial Frame (TSF) or Ilizarov frames in treatment of high-energy tibia fractures in a tertiary trauma referral centre. Methodology. Retrospective review of consecutive series identified two treatment groups; Group 1(TSF) and Group 2 (Ilizarov). Time in frame (healing time) was defined as time from insertion to removal of frame. All patients with incomplete data secondary to loss to follow-up or death were eliminated. Results. Data was available for 112 patients (Group 1 N37 and Group 2 N85) with average ages for of 46.43 and 44.64 years respectively and a male to female ratio of 23:14 and 63:22. 7 open tibial fractures and 24 distal tibia fractures were treated in Group 1 with 18 open tibia fractures and 24 pilon fractures in Group 2. Average healing time was 174.35 (124–340) and 176.41 (102–555) days respectively. Smoker's average healing time was 181.86 and 213.86 days per group. Non-smokers average healing time was 161.86 and 174 days for the two groups. N5 and N26 patients were recorded as high-energy injuries with associated other multiple fractures or visceral injuries with average frame times of 192.2 and 194.69 days respectively. All fractures went to union with only one infection in the Ilizarov group. Conclusion. Smoking and associated high-energy injuries lead to an increase in healing time for both groups. Despite the rigid nature of TSF, healing time is similar to Ilizarov frame

Aims

Ankle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest.

The treatment of very distal tibial fractures and pilon fractures is difficult. There is a wide variation in the severity of injury and the options for surgical management. Plates and external fixation each have their advantages. This retrospective study looks at complications and technical tips for anterolateral plating. 35 consecutive distal tibial platings were evaluated. The AO classification for each fracture was determined and any patient factors affecting outcome. Outcome variables included time to radiological union, infection rate, wound breakdown rate, and joint movement after treatment. There were 32 anterolateral platings and 3 medial platings. The union rate was 95%. There were two deep infections which required surgical treatment. There were two wound breakdowns, one of which required plastic surgical intervention. Two patients had prominent metalwork, requiring removal. Other complications included deep peroneal nerve palsy, stiffness, and vascular compromise. The complication rates were lower for surgeons operating more frequently on these fractures. Two patients subsequently required bone transport and one required an amputation. The complication rate found was similar to that reported in the literature. The few complications were however very significant for the patient and also for the surgeon as they required bone transport. Complications other than infection occurred in the few cases performed by surgeons low on their learning curve. We present technical tips for surgery. The presence of callus only after mobilisation indicates that union is slow. Anterolateral plating is a viable option for distal tibial fractures, especially 43B fractures. There is a learning curve associated with their use. Complication rates are low overall, but significant consequences can accompany complications. As an alternative to external fixation, distal locking plates are not a pain free option for the surgeon, as well as for the patient

Aims

Paediatric triplane fractures and adult trimalleolar ankle fractures both arise from a supination external rotation injury. By relating the experience of adult to paediatric fractures, clarification has been sought on the sequence of injury, ligament involvement, and fracture pattern of triplane fractures. This study explores the similarities between triplane and trimalleolar fractures for each stage of the Lauge-Hansen classification, with the aim of aiding reduction and fixation techniques.

The upper and lower thirds of the tibia are areas of peculiar anatomy and pose a lot of problems in their treatment. Purpose We present a method of hybrid external fixation used in a wide variety of these fractures. Material and method: Between 2000 and 2004, 29 patients with fractures of the tibia (16 fractures of the lower third and 13 fractures of the upper third) were treated with hybrid external fixation ORTHOFIX. Most of the fractures involved the adjacent joints, 12 fractures of the tibial condyles and 9 pilon fractures. Among the patients, 5 had septic non-union 2 of who were submitted to bone transport with the attachment of a lengthening system. All patients were called for monthly follow up till union. Results: In all cases except one (septic non-union – bone transport of the lower third) there was successful union by 3 to 7 months postoperatively. There was no malalignment, no deep infection or other major complication. Conclusion: The rational use of the hybrid external fixation offers a valuable solution in the treatment of the complex fractures in the upper and lower third of the tibia

We describe a new surgical approach designed for use with minimally invasive fixation and a circular frame. Tibial pilon injuries are often associated with significant soft tissue injury, which may not be evident at the time of injury. In such cases standard surgical approaches can lead to problems with wound healing, thus increase the risk of deep infection. AO Type C valgus fractures are commonly associated with fibula fractures. We found that the anterior syndesmotic ligaments are often disrupted with sparing of the lateral soft tissue envelope. Our technique utilizes a direct lateral approach to expose the lateral malleolus/distal fibula, which is reflected postero-laterally through the fracture and intact posterior syndesmotic ligaments. This creates a direct view of posterolateral and anterolateral comminution and talar dome allowing direct fixation of fragments with minimal internal fixation. Fibula fixation is performed with a 1/3. rd. tubular plate and the anterior syndesmotic ligaments are repaired. From 2007–2009, we used this approach in 12 patients (Male 9: Female 3; age 19–42) with AO Type C3 fractures with significant soft tissue injury (open = 2/ closed = 10; Tscherne Grade 1 = 4; Grade 2 = 8). We used circular frame stabilization in all cases (in four patients an additional foot frame was applied to protect the articular surface). All fractures united in satisfactory alignment. Wound healed well in all cases. One case of gouty arthritis developed superficial infection, which went on to heal after wound wash out and oral antibiotic therapy. Follow-up (minimum 3 months and maximum 2 years) showed no ankle instability. Clinical evaluation revealed a mean dorsiflexion of 10° (5–15°) and mean plantar flexion of 35° (15–60°). We conclude that transfibular approach gives good exposure of lower tibial articular surface in selected cases of pilon fractures with least soft tissue disruption

32 consecutive patients who suffered open [Gustilo grade IIIB] distal tibial [AO type 43B and C] ‘Pilon’ fractures were prospectively studied in order to assess long-term functional outcome. All patients had radical debridement with immediate [within 24hrs] skeletal stabilisation and early soft tissue cover with a vascularized muscle flap as per our hospital’s protocol for management of severe open tibial fractures. The minimum follow-up was one year [range 1–8 years]. The superficial infection rate was 13% [4/32], deep infection rate was 6% [2/32] and the amputation rate as 6% [2/32]. There were no long-term problems with union and none of the patients required an ankle fusion. Patients were assessed using the SF-36 questionnaire. There were sig-nificant differences from the US norm in physical function score [p< 0.01], role physical score (p< 0.05) and physical component score (p< 0.01). Physical component score of 38.5 was significantly better (p< 0.01) when compared with amputees from severe lower extremity trauma. Our protocol for management of severe open pilon fractures resulted in a good functional outcome with low infection and amputation rates

Fractures of lower limb treated with Open Reduction and Internal Fixation (O.R.I.F.) are frequently complicated in the postoperative period. Minimal Invasive Plate Osteosynthesis (MIPO) is developing for subcutaneous plating. The purpose of this study is to demonstrate the improvement in dropping the risks of complications following internal fixation using MIPO. From January 1998 to May 1999 we collected 32 cases of lower limb fractures treated with O.R.I.F (Group I). From June 1999 we started to perform MIPO in closed fractures of lower limb with conventional and new devices with angular stability that offer more mechanical stability (Group II 90 cases). In Group I we got 2 infections in pilon fractures, 3 delayed union in distal tibial fractures, 1 non-union in distal femoral fracture, 1 varus deformity in distal femoral fracture and 2 DVT. In Group II we had only 4 cases of varus deformity and 1 DVT. The findings of this study justify the effort to follow this procedure also because the new devices available improved mechanical stability. MIPO is a demanding technique with undoubted advantages: it respects the biology of callus and soft tissues, it reduces the necessity of bone graft and is particularly indicated in polytrauma patients

Pilon fractures of the distal tibia pose a difficult therapeutic problem. Various treatment methods exist. We present encouraging early results with the Medial Tibial LISS plate (LCDCP) for these injuries. Materials and Methods: 7 patients (5 male:2 female); age: 34 (range 26–59); All closed injuries 3 type 1; 3 type 2; 1 type IIIc; Average time from injury to surgery: 6 days (4–12 days). Technique: 4 patients had preliminary joint-spanning fixator; 4 patients had fibular plating through a posterolateral incision; A curved anteromedial incision was used to avoid plate exposure in case of wound breakdown. Medial Tibial LISS plate with inter-fragmentary screws to reduce main fracture fragments. Early, non-weight bearing mobilization. Results: Minimum Follow Up: 6 months (range 6–18 months). Union was obtained in all fractures. Joint reconstruction was graded as anatomical in 3 patients, mildly non-anatomical in 3 patients, and markedly incongruent in 1 patient (Type IIIc3). ROM: average 10° Dorsiflexion and 30° Plantarflexion. Pain: None in 4, mild in 2, and severe in 1. Wound healing problems: 1 minor requiring no surgical intervention, 1 requiring debridement of distal tibial wound. We conclude that this technique offers a viable alternative to other methods in the treatment of these difficult injuries

This paper describes the outcome of type III pilon fractures of the distal tibia treated primarily with an llizarov ring fixator. Only patients with intra-articular fracture of the tibial plafond on plain radiographs that corresponded to type III pattern of Ruedi and Allgower were included. There were thirteen patients with a mean age of 45 (range 29–65), twelve males and one female. The mechanism of injury in all the patients was high-speed road traffic accident. Operative fixation consisted of fracture reduction and stabilisation using the Ilizarov circular frame external fixator and olive tipped wires. Further insult to the already damaged soft tissues was avoided. Bony union was achieved in all cases. Treatment in the frame lasted between 3 and 10 months (average of 6.3 months). Neither deep infection nor soft tissue complications occurred. Outcomes measured using the Olerud ankle score, modified Ovadia and Beals radiological criteria, and the SF-36 Health Questionnaire and our results compare well with other fixation techniques. The use of the llizarov circular frame external fixator without any additional internal reduction or fixation procedures is a definite option for the treatment of these high-energy injuries

This paper describes the outcome of type III pilon fractures of the distal tibia treated primarily with an Ilizarov ring fixator. Only patients with an intra-articular fracture of the tibial plafond on plainradiographs that corresponded to type III pattern with the system of Rfiedi andAllgower were included. There were thirteen patients with a mean age of 45 (range 29–65), twelve males and one female. The mechanism of injury in all the patients was high-speed road traffic accident. Operative fixation consisted of fracture reduction and stabilisation using the llizarov circular frame external fixator and olive tipped wires. Further insult to the already damaged soft tissues was avoided. Bony union was achieved in all cases. Treatment in the frame lasted between 3 and 10 months (average 6. 3 months). Neither deep infection nor soft tissue complications occurred. Outcome measurements included the Olerud ankle score, modified Ovadia and Beals radiological criteria, and the SF-36 Health Questionnaire. Wound and deep infections were successfully avoided and bony union was achieved in all our patients. This compares well with other fixation techniques. The use of the llizarov circular frame external fixator without any additional internal reduction or fixation procedures is a definite option for the treatment of these high-energy injuries

Objective: To evaluate retrospectivelly the outcome of periarticular tibial pilon fractures treated by hybrid external fixation. Method: Between 1999–2003, 44 patients(44 fractures) were treated with a combination of hybrid external fixation and minimal internal fixation(k-wires or lag-screws). There were 31 men and 13 women with a mean age of 41 years. A high energy trauma( accident or fall from a height) was the mechanism of injury for 32(73%) patients. According with A.O. clasiffication 4 fractures were A1, 5-A2, 5-A3, 8-C1, 12-C2,10-C3. All fractures were treated within a 10 days from the initial injury (10(23%) of them were open and treated immediately). The use of bone grafts reguired in 8 cases. Primary postop mobilization of adjacent joints was performed in all cases. Fourty patients were available for clinical and radiographic evaluation(using Teeny’s and Wiss ancle score). The average follow-up was 26 months. Results: There were 9(23%) excellent, 12(30%) good, 10(25%) fair, and 9(23%) poor results. Union achieved in 40(92%) cases. Overall, 12(30%) complications reported: 6 pin track infections, 2 deep infections, 4 non-unions and 1 malunion. Post-traumatic osteoarthritis noticed in 11(28%) cases. Conclusions: Hybrid external fixation permits early mobilization of the ankle joint and decrease the soft tissue trauma. Poor results associated with the presence of infection, the degree of intraarticular involvement and the inability to achieve adeguate fracture reduction

Introduction The purpose of this paper is to illustrate the role of MDCT (multislice or multi-detector row computerised tomography) in the acquisition of information in musculoskeletal pathology and the subsequent manipulation of this data in obtaining 3D reconstruction to aid surgical planning. Methods Numerous CT studies were performed on patients who had sustained significant and often complex injuries, including pelvic, acetabular, femoral head, proximal tibial and pilon fractures. The images were acquired on GE lightspeed scanners and post processed using advantage window workstations. The 3D imaging was then used in the planning of surgery. This allowed the accurate assessment of site and extent of fracture displacement as well as a 3D appreciation of any deformity present. Results The images obtained were displayed using multiple formats: axially acquired source images, multiplanar isotropic reformatted images and 3D surface or volume-rendered images. The facility of being able to remove a particular bare to view adjacent bony structures increases the ability to assess the anatomical nature of a clinical problem. Conclusions Multislice CT with 3D reconstructions is an extremely useful diagnostic tool in aiding surgical planning for trauma cases. In addition, the ability to rotate images on the workstation and obtain multiple perspectives, as well as being able to remove osseous structures to view adjacent bones with greater clarity provides useful additional information. In relation to the conduct of this study, one or more of the authors is in receipt of a research grant from a non-commercial source

Aims: The evaluation of indications and results of the treatment of C fractures (according to AO) of the distal tibia with hybrid external þxation. Method: Between 1998–2001 thirty-one patients (22 men and 9 women), all available to follow-up, with 31 tibial pilon fractures were managed with hybrid external þxation. Mean follow-up time was 18 months and mean age 35 years (17–76). Seven were open fractures. Closed reduction (ligamentotaxis) and application of hybrid external þxation was done in 22 cases, while in 9 patients minimal open reduction, use of autologous bone grafts and minimal additional internal þxation was necessary. Mobilization of the ankle started at the 3rd postoperative day. The average time of healing was 4.2 months. Final evaluation was done according to evaluation criteria proposed by P. Tornetta III. Results: Fourteen patients (87%) had good and excellent, 2 (6.4%) fair and 2 (6.4%) poor. Complications were 1 valgus deformity > 8û, 1 nonunion, and 4 pin tract infections treated with p.o. antibiotics. Conclusions: Use of hybrid external þxation in C fractures allows anatomic reduction of the fragments with minimal invasion and immediate mobilization of the ankle join and early weight bearing. Open reduction is minimal and seldom needed. Pin site infection could occur

Ten patients, who underwent treatment for complex fracture-dislocation of the proximal interphalangeal joint of finger and one patient for that of the interphalangeal joint of thumb with a modified pins and rubbers traction system, were reviewed to evaluate the clinical and functional results. Two patients had open fracture-dislocation, 5 had pilon fractures and 4 had fracture-dislocations. The system was modified to avoid rotation of the pins in the bone during joint mobilization, thus minimizing the risk of osteolysis due to friction of pins over the bone. Michigan hand scoring system was used for subjective assessment and range of motion at proximal and distal interphalangeal joints and grip strength for objective assessment. Average follow-up was 18 months (range 3 months to 28 months). The average normalised Michigan hand score was 86. Based on Michigan scores, overall hand function was rated excellent in 8 patients, good in 2 and poor in 1. Eight patients have returned to their original jobs. The average arc of flexion in the proximal interphalangeal joint was 85 degrees and in the distal interphalangeal joint it was 47 degrees. The average grip strength was 95 percent of the uninvolved side. Two patients developed minor pin site infection, which did not necessitate pin removal or any alteration in the treatment regime. There have been no cases of osteolysis, osteitis or osteomyelitis. This modification of pins and rubbers traction system has given very acceptable results with a low complication rate. It is light, cheap, effective and easy to apply

Purpose: To evaluate the appropriateness of posterior blade plate ankle arthrodesis as a salvage procedure, in a complex subgroup of ankle trauma patients. Methods: We retrospectively identified all patients who underwent an ankle arthrodesis from our prospectively collected trauma database at Vancouver General hospital from 1997 to 2005. We then extracted those who had blade plate arthrodesis via the posterior approach for previous failed fracture fixation or failed previous fusion. Demographics, pre arthrodesis diagnosis, previous surgeries, deformity and complications were recorded. Clinical examination was based on outpatient evaluation and physical evaluation. This was supplemented with radiological follow up to confirm union and outcome scoring using the AOFAS and SF36 systems. Results: Sixteen patients were identified from the trauma database who had undergone posterior blade plate ankle arthrodesis. Of these thirteen were available for follow up. There average age was 47 years (range 23–63 years). The male to female ratio was 3:1. Three cases were for failed previous ankle fusion by other means. Of the remaining ten patients with post traumatic osteoarthritis, seven had previous pilon fractures, two talar fractures and one fracture dislocated ankle. All cases went onto bony union. Patient satisfaction was good although functional outcome scoring was not normal. Conclusion: We have found this procedure to have several excellent benefits. It allows the surgeon to operate through virgin skin, reducing potential wound complications, and achieve good soft tissue coverage. The blade plate allows reconstitution of a normal plantar grade ankle and distal tibial orientation, when secured appropriately to bone. Excellent compression and union can be achieved with the AO compression device, but it’s important to have a second screw in the talus to prevent blade pull out. The procedure has good satisfaction among patients following previous failed surgery, as a salvage procedure

A prospective study on the management of 23 patients with complex high energy tibial fractures was carried out to assess the outcome following the use of different external fixators. They were all followed up clinically and radio logically till fracture union. The average age 42 years (range 13–77 years) 17 male & 6 females. Fourteen were closed and 9 open. Eight were falls from height, 9 RTAs, one crush injury and one assault. All of the open fractures were grade 3. Six patients had proximal tibial fractures (one Schatzker Type-II, one Type-IV, two Type-V and two Type-VI) They united at an average of 20 weeks (range 10–40 weeks). Seven were Shaft fractures average duration to union 30 weeks (range 8–104 weeks), and eight were Pilon fractures (Two Ruedi & Allgower Type-II & Six Type-III) they united at an average duration of 13 weeks (range 7–20 weeks). All patients achieved clinical and radiological union at a mean duration of 22 weeks. Sheffield Ring fixator [SRF] was used primarily in 11 patients, none failed. Two had initial monolateral fixators which were converted to SRF. Two were managed with Illizarov frames and three with hybrid fixators. Seven patients had an initial monolateral fixator, two failed and were converted to a Sheffield fixator, 2 planned conversion to an intramedullary nail, one developed a delayed union and was converted to a Sheffield fixator, only two continued till union. Nine patients developed pin tract infection needing Antibiotics, three of them developed Osteomyelitis, Four had failure of fixation needing a second operation. Two developed malunion, one managed with total knee replacement, another required Ankle fusion. The average SF 12 score for the Sheffield group PCS was 52.1 and MCS of 51.7. For the Monolateral fixator group PCS was 47.2 and MCS of 48.1. For the Hybrid fixator group PCS of 34.7 and MCS of 42.7 and for the Ilizarov group PCS was 39.85 and MCS was 55.05. In this cohort of complicated High energy Tibial fractures, those managed with Circular Frames especially SCF augmented with interfragmantary screws proved to be most successful with a very lower failure rate and better patient satisfaction

Introduction: Ankle fractures are among the commonest orthopaedic injuries. A delay in operating is often due to the swelling associated with such fractures. On the other hand, the delay in operative fixation beyond 24 h from injury is associated with a lengthening of hospital stay which costs approximately £225 per patient per day for an acute trauma bed. Objectives: The aim of this study was to analyse the relationship between the delay in surgical intervention of open reduction and internal fixation of ankle fractures from presentation due to ankle swelling, and the length of hospital stay and postoperative complications. Patients and Methods: A retrospective study of 145 consecutive patients treated for ankle fractures over a period of 12 months between January and December 2008. results were collated excluding talar and pilon fractures. Emergency department presentation times were noted and time of anaesthetic to determine surgical delay. Notes were reviewed for inpatient stay and postoperative complications. Results: There were 62 male and 83 female patients with a mean age of 49 years. In total, 117 (80%) patients were operated on within 24 hours of presentation (early group). 28 patients’ surgery was delayed beyond 24 hours (delayed group). Of the 117 patients the mean inpatient stay was 3.79 days (± 2.39) whereas in the delayed group the mean stay was 8.57 days (± 6.54). Of the delayed group, 57% of the cases had swelling as the cause of a postponed operation, whereas other causes included lack of theatre time and lack of fitness for surgery. In the early group, 5 patients (4.27%) had wound infections and one patient had a chest infection (0.85%). Four patients (14.28%) from the delayed group developed wound infections all of whom were from patients with ankle swelling. Conclusion: We recommend that policies be put in place to provide early operative intervention for patients with fractured ankles prior to the development of swelling as this would result in improved patient outcome and significant financial savings. If an operation is not feasible within 24 hours of admission and the ankle is swollen resulting in a high operative risk, we recommend sending the patient home for a period of 5–7 days with advice on RICE and anticoagulation which would both permit surgery and cut down costs

This study of surgically treated distal tibia fractures was undertaken to compare the internal fixation with the two external fixation methods. There were 40 patients with 41 pilon fractures. The mean age was 51.2 years (18–76). 17 of the 40 patients-14 from vehicular accident, 3 from fall – were treated with an ankle-spanning half-pin external fixator (11C, 6B, 11 Weber B- 5 C, 1IIIa, 5I, 6II). 11 patients-10 from vehicular accident, 1 from fall- were treated with a single-ring hybrid ankle-spanning external fixator (9C, 2 B, 6 Weber B-4 C, 5I, 2II). 13 patients-10 from vehicular accident and 1 from fall- were treated with an epiunion plate (1A, 8B, 4C, 5I, 3II, 10 Weber B- 1C). The mean follow-up was 4.2years (1–8). Fracture union was defined as having three cortices bridging on the plain radiographs for a patient who was able to bear full weight. Non union was defined as a fracture that did not heal within a year. Fracture union was achieved for 36 of the 41 fractures. Three patients with external fixator, one with hybrid and one with plate had septic pseudarthrosis. Fractures in the external fixator and hybrid groups had a tendency to lose the reduction. Four patients with external fixator had delayed union and have lost range of motion in the ankle. Five patients in the external fixator group are candidates for ankle arthrodesis due to arthritis. The ORIF and hybrid fixator were equally efficacious in achieving bony union and not to lose range of motion in the ankle. Fractures in the external fixator with the ankle – spanning had higher rate of delayed union and loss of motion in ankle. The choice of the external fixator is dependent on the surgeon and the type of the fracture. However the patient must be followed up for the stability of the system

AIMS. Pure tibial plafond traumatic pathology (excluding trimalleolar fractures) is rare but troublesome, considering the surgical challenges and the long term disability perspective. Treatment involves a wide variety of implants and techniques, and the procedures choice and timing is highly dictated by the soft tissue damage. We designed this study to assess the status of our patients operated with internal, external or combined procedures. METHODS. In a retrospective study, between July 2008 and July 2010 we reviewed 24 patients with available follow-up data. We reviewed the pre- and post-operative imaging available and the immediate follow-up data. A form is currently mailed to the patients to self-evaluate the general physical, mental and employment status, and also the affected limb, using general approved questionnaires. Data from this form is still in process. RESULTS. In this clinic we recorded 24 patients with tibial plafond fractures (17 male, 7 female, 2.43 sex ratio), with ages between 18 and 82 years (average 46.5, median 39 years). According to AO/OTA classification, we noted 8 type A (2 A1, 3 A2, 3 A3) extra-articular tibial fractures, 9 type B (4 B1, 4 B2, 1 B3) intra-articular pilon fractures and 7 type C (3 C1, 1 C2, 3 C3) both epi- and metaphyseal tibial fractures, usually with peroneus fractures at various levels. 10 of these fractures were open, from them 3 type IIIA and 2 IIIB Gustilo-Anderson, and 3 of the patients were politrauma (1 L1 lumbar fracture and distal radius fracture, 1 cranio-cerebral trauma and type I open distal radius fracture and 1 cranio-cerebral trauma). We performed a large array of surgical procedures, usually in emergency, based mainly on the local soft tissue status and both the age and recovery needs of the patient. In old debilitated patients we preferred to use minimal internal osteosynthesis, usually applying a supplementary external fixator or cast. In young active patients we used MIPO techniques in tibial fractures, both with regular or locking-screw plates, repairing also the peroneus in order to preserve the limb length in diaphyseal fractures, and to reconstruct the ankle in lateral malleolus fractures. In cases with severe soft tissue impairment we delayed the definitive osteosynthesis using an external fixator. The short term outcome was good, noting only one septic nonunion, which healed with the appropriate treatment, one calcaneus pin track infection and one deterioration of the external fixator in an alcoholic patient. Data for the mid-term outcome is still under evaluation. CONCLUSIONS. Choosing the appropriate procedure is vital for the outcome. Timing is important, especially in high energy trauma, when the proper surgery performed in emergency allowed us to overcome most of the possible complications. Short term results are encouraging, and the mid-term results will let us know if our attitude was correct
