Aims. To describe outcome reporting variation and trends in non-pharmacological randomized clinical trials (RCTs) of distal tibia and/or ankle fractures. Methods. Five electronic databases and three clinical trial registries were searched (January 2000 to February 2022). Trials including patients with distal tibia and/or ankle fractures without concomitant injuries were included. One reviewer conducted all searches, screened titles and abstracts, assessed eligibility, and completed data extraction; a random 10% subset were independently assessed and extracted by a second reviewer at each stage. All extracted outcomes were mapped to a modified version of the International Classification of Functioning, Disability and Health framework. The quality of outcome reporting (reproducibility) was assessed. Results. Overall, 105 trials (n = 16 to 669 participants) from 27 countries were included. Trials compared surgical interventions (n = 62), post-surgical management options (n = 17), rehabilitative interventions (n = 14), surgical versus non-surgical interventions (n = 6), and pre-surgical management strategies (n = 5). In total, 888 outcome assessments were reported across seven domains: 263 assessed body structure or function (85.7% of trials), 136 activities (68.6% of trials), 34 participation (23.8% of trials), 159 health-related quality of life (61.9% of trials), 247 processes of care (80% of trials), 21 patient experiences (15.2% of trials), and 28 economic impact (8.6% of trials). From these, 337 discrete outcomes were described. Outcome reporting was inconsistent across trials. The quality of reporting varied widely (reproducibility ranged 4.8% patient experience to 100% complications). Conclusion. Substantial heterogeneity in outcome selection, assessment methods, and reporting quality were described. Despite the large number of outcomes, few are reported across multiple trials. Most outcomes are clinically focused, with little attention to the long-term consequences important to patients. Poor reporting quality reduces confidence in data quality, inhibiting data synthesis by which to inform care decisions. Outcome reporting guidance and standardization, which captures the outcomes that matter to multiple stakeholders, are urgently required. Cite this article: Bone Jt Open 2022;3(10):832–840

Aims. We retrospectively report our experience of managing 30 patients with a primary malignant tumour of the distal tibia; 25 were treated by limb salvage surgery and five by amputation. We compared the clinical outcomes of following the use of different methods of reconstruction. Patients and Methods. There were 19 male and 11 female patients. The mean age of the patients was 19 years (6 to 59) and the mean follow-up was 5.1 years (1.25 to 12.58). Massive allograft was used in 11 patients, and autograft was used in 14 patients. The time to union, the survival time of the reconstruction, complication rate, and functional outcomes following the different surgical techniques were compared. The overall patient survival was also recorded. Results. Out of 14 patients treated with an autograft, 12 (86%) achieved union at both the proximal and distal junctions. The time to union at both junctions of the autograft was significantly shorter than in those treated with an allograft (11.1 vs 17.2 months, p = 0.02; 9.5 vs 16.2 months, p = 0.04). The complication rate of allograft reconstruction was 55%. The five patients treated with an amputation did not have a complication. Out of the 25 patients who were treated with limb salvage, three (12%) developed local recurrence and underwent amputation. The mean functional Musculoskeletal Tumor Society (MSTS) score after autograft reconstruction was higher than after allograft reconstruction (81% vs 67%; p = 0.06), and similar to that after amputation (81% vs 82%; p = 0.82). The two- and five-year overall rates of survival were 83% and 70%, respectively. Conclusions. This consecutive case series supports the safety of limb salvage and the effectiveness of biological reconstruction after the resection of a primary tumour of the distal tibia. Autograft might be a preferable option. In some circumstances, below-knee amputation remains a valid option

The ideal form of fixation for displaced, extra-articular fractures of the distal tibia remains controversial. In the UK, open reduction and internal fixation with locking-plates and intramedullary nailing are the two most common forms of treatment. Both techniques provide reliable fixation but both are associated with specific complications. There is little information regarding the functional recovery following either procedure. We performed a randomised pilot trial to determine the functional outcome of 24 adult patients treated with either a locking-plate (n = 12) or an intramedullary nailing (n = 12). At six months, there was an adjusted difference of 13 points in the Disability Rating Index in favour of the intramedullary nail. However, this was not statistically significant in this pilot trial (p = 0.498). A total of seven patients required further surgery in the locking-plate group and one in the intramedullary nail group. This study suggests that there may be clinically relevant, functional differences in patients treated with nail versus locking-plate fixation for fractures of the distal tibia and differences in related complications. Further trials are required to confirm the findings of this pilot investigation

Aims. To report the outcomes of patients with a fracture of the distal tibia who were treated with intramedullary nail versus locking plate in the five years after participating in the Fixation of Distal Tibia fracture (FixDT) trial. Methods. The FixDT trial reported the results for 321 patients randomized to nail or locking plate fixation in the first 12 months after their injury. In this follow-up study, we report the results of 170 of the original participants who agreed to be followed up until five years. Participants reported their Disability Rating Index (DRI) and health-related quality of life (EuroQol five-dimension three-level questionnaire) annually by self-reported questionnaire. Further surgical interventions related to the fracture were also recorded. Results. There was no evidence of a difference in patient-reported disability, health-related quality of life, or the need for further surgery between participants treated with either type of fixation at five years. Considering the combined results for all participants, there was no significant change in DRI scores after the first 12 months of follow-up (difference between 12 and 24 months, 3.3 (95% confidence interval -1.8 to 8.5); p = 0.203), with patients reporting around 20% disability at five years. Conclusion. This study shows that the moderate levels of disability and reduced quality of life reported by participants 12 months after a fracture of the distal tibia persist in the medium term, with little evidence of improvement after the first year.

Aims. To systematically review qualitative studies of patients with distal tibia or ankle fracture, and explore their experience of injury and recovery. Methods. We undertook a systematic review of qualitative studies. Five databases were searched from inception to 1 February 2022. All titles and abstracts were screened, and a subset were independently assessed. Methodological quality was appraised using the Critical Appraisal Skills Programme (CASP) checklist. The GRADE-CERQual checklist was used to assign confidence ratings. Thematic synthesis was used to analyze data with the identification of codes which were drawn together to form subthemes and then themes. Results. From 2,682 records, 15 studies were reviewed in full and four included in the review. A total of 72 patients were included across the four studies (47 female; mean age 50 years (17 to 80)). Methodological quality was high for all studies, and the GRADE-CERQual checklist provided confidence that the findings were an adequate representation of patient experience of distal tibia or ankle fracture. A central concept of ‘being the same but different’ conveyed the substantial disruption to patients’ self-identity caused by their injury. Patient experience of ‘being the same but different’ was expressed through three interrelated themes, with seven subthemes: i) being proactive where persistence, doing things differently and keeping busy prevailed; ii) living with change including symptoms, and living differently due to challenges at work and leisure; and iii) striving for normality, adapting while lacking in confidence, and feeling fearful and concerned about the future. Conclusion. Ankle injuries were disruptive, draining, and impacted on patients’ wellbeing. Substantial short- and longer-term challenges were experienced during recovery. Rehabilitation and psychosocial treatment strategies may help to ameliorate these challenges. Patients may benefit from clinicians being cognisant of patient experience when assessing, treating, and discussing expectations and outcomes with patients.

Aims. The aim of this study was to report the results of three forms of reconstruction for patients with a ditsl tibial bone tumour: an intercalary resection and reconstruction, an osteoarticular reconstruction, and arthrodesis of the ankle. Methods. A total of 73 patients with a median age of 19 years (interquartile range (IQR) 14 to 36) were included in this retrospective, multicentre study. Results. Reconstructions included intercalary resection in 17 patients, osteoarticular reconstruction in 11, and ankle arthrodesis in 45. The median follow-up was 77 months (IQR 35 to 130). Local recurrence occurred in eight patients after a median of 14 months (IQR 9 to 36), without a correlation with adequacy of margins or reconstructive technique. Major complications included fracture of the graft in ten patients, nonunion of the proximal osteotomy in seven, and infection in five. In the osteoarticular group, three of 11 patients developed radiological evidence of severe osteoarthritis, but only one was symptomatic and required conversion to ankle arthrodesis. Functional evaluation showed higher values of the Musculoskeletal Tumour Society (MSTS) and American Orthopaedic Foot and Ankle Society (AOFAS) scores in the intercalary group compared with the others. Conclusion. Preservation of the epiphysis in patients with a distal tibial bone tumour is a safe and effective form of limb-sparing treatment. It requires rigorous preoperative planning after accurate analysis of the imaging. When joint-sparing resection is not indicated, ankle arthrodesis, either isolated tibiotalar or combined tibiotalar and subtalar arthrodesis, should be preferred over osteoarticular reconstruction.

We have carried out prosthetic reconstruction in six patients with malignant or aggressively benign bone tumours of the distal tibia or fibula. The diagnoses were osteosarcoma in four patients, parosteal osteosarcoma in one and recurrent giant-cell tumour in one. Five tumours were in the distal tibia and one in the distal fibula. The mean duration of follow-up was 5.3 years (2.0 to 7.1). Reconstruction was achieved using custom-made, hinged prostheses which replaced the distal tibia and the ankle. The mean range of ankle movement after operation was 31° and the joints were stable. The average functional score according to the system of the International Society of Limb Salvage was 24.2 and five of the patients had a good outcome. Complications occurred in two with wound infection and talar collapse. All patients were free from neoplastic disease at the latest follow-up. Prosthetic reconstruction may be used for the treatment of malignant tumours of the distal tibia and fibula in selected patients

The purpose of this study was to evaluate and to compare the mechanical stability of external fixation with and without ankle spanning fixation using a foot plate in an in-vitro model of periarticular distal tibia osteotomy/fracture. Ten fresh frozen lower extremities (five pairs) with a simulated distal tibia osteotomy/fracture were stabilised with an Ilizarov hybrid fixator with and without a foot plate. All specimens were loaded using a servohydraulic load frame. Relative interfragmentary motions (vertical and horizontal translations, and rotation) were measured. Statistical analysis was performed as a paired t-test to compare the different frame constructs. A p<0.05 was considered indicative of a significant difference between fixator constructs. The vertical displacement measured at the centre of the distal fragment under load with the foot plate was such that the bone fragments became closer together (-0.83±0.64 mm). Loading of specimens without the foot plate resulted in distraction of the distal fragment (2.57±0.97 mm). The difference was statistically significant (p<0.05). The horizontal displacement of distal fragment with (1.12±0.98 mm) was not significantly different from the motion without (1.19±1.23 mm) a foot plate and was in the anterior direction in both cases. Loading of the construct with the foot plate caused sagittal plane angulation of the fragments with the osteotomy/fracture gap opening anteriorly (-1.15±0.61 deg.). Loading of the construct without a foot plate resulted in sagittal plane angulation of fragments with the gap opening posteriorly (4.49±0.45 deg.). These motion differences were statistically significant (p<0.05). There was not a statistically significant difference between the order of testing the construct with a foot plate and the construct without it (p>0.05). Fixators with ankle spanning using foot plates increase the mechanical stiffness of external fixation of periarticular distal tibia osteotomy/fracture

Introduction: Unstable fractures of the distal tibia that are not suitable for intramedullary nailing are commonly treated by open reduction and internal þxation and/or external þxation techniques. Treatment of these injuries using minimally invasive plate osteosynthesis (MIPO) techniques may offer the advantage of achieving adequate þxation whilst minimising soft tissue injury and damage to the vascular integrity of the fracture fragments. Purpose: We report our experience using MIPO techniques for the treatment of unstable fractures of the distal tibia. Method: A review of all patients who sustained an unstable fracture of the distal tibia treated by MIPO between 1998 and 2001 was undertaken. Twenty patients were identiþed. The mean age was 38.3 years (17 Ð 71). All fractures were closed, and were classiþed according to the AO system. Intra-articular fracture extensions were classiþed according to RŸedi and Allgšwer. Results: Sixty percent of patients achieved callus by 8 weeks. All patients achieved callus by 3 months. The mean time to full weight bearing was 12 weeks (8 Ð 17). By 6 months 18/20 patients had achieved union. The two remaining patients achieved union by 7 months without further surgery. There were no deep infections and only one malunion. There were no cases of failure of þxation. Conclusion: MIPO appears to offer a reliable method of þxation of fractures of the distal tibia that are unsuitable for intramedullary nailing. Our results suggest that this technique is associated with a lower risk of signiþcant complications than encountered with more traditional methods of þxation of such fractures

Endoprosthetic replacement of the distal tibia and ankle joint for a primary bone tumour is a rarely attempted and technically challenging procedure. We report the outcome of six patients treated between 1981 and 2007. There were four males and two females, with a mean age of 43.5 years (15 to 75), and a mean follow-up of 9.6 years (1 to 27). No patient developed a local recurrence or metastasis. Two of the six went on to have a below-knee amputation for persistent infection after a mean 16 months (1 to 31). The four patients who retained their endoprosthesis had a mean musculoskeletal tumour society score of 70% and a mean Toronto extremity salvage score of 71%. All were pain free and able to perform most activities of daily living in comfort. A custom-made endoprosthetic replacement of the distal tibia and ankle joint is a viable treatment option for carefully selected patients with a primary bone tumour. Patients should, however, be informed of the risk of infection and the potential need for amputation if this cannot be controlled

Aims: There has been recent interest in the use of external þxation for the treatment of distal peri-articular fractures. The current study was undertaken to evaluate the role of the hybrid external þxation system in the treatment of the distal tibial fractures. Methods: We treated 137 fractures of the distal tibia, of which 46 were treated with hybrid external þxation. The indication for this method of treatment was in the presence of an unstable extra-articular fracture and/or a severe comminution of the distal tibia, as well as an associated severe soft-tissue injury. Routine demographic data, clinical and radiographic þndings as well as reduction, outcomes and complications were recorded. Patients were evaluated with outcome scale of Ovadia and Beals. Results: There were 17 closed fractures and 29 open. Twenty-one extra -and 25 intrarticular fractures were managed with a Hybrid Fixator. All fractures achieved complete healing. Reductions of C-type fractures were within 0-2 mm in 16 and 3–5mm in 56 and > 5mm in 3 patients. The Hybrid External þxator was removed at an average of 17.5 weeks. Full weight bearing was achieved at a mean of 7.8 weeks. There were no intraoperative injuries to nerves or major vessels. Using the outcome scale of Ovadia and Beals, good-excellent results were achieved in 67% (n=31) subjectively and 72% (n=33) objectively. Two poor results occurred in patients with a varus malunion. Conclusion: External þxation is a satisfactory method of treatment for fractures of the distal tibia and is associated with fewer complications than internal þxation, because it limits the amount of soft tissue

Introduction: Primary or secondary bone tumours of the distal tibia are uncommon. Before the development of endoprostheses in the 1970’s, the primary treatment for these was below knee amputation. Limb salvage is now possible without adversely affecting survival largely due to improvements in chemotherapy. We report the clinical and functional outcome of six patients who underwent limb salvage with endoprosthetic reconstruction of the distal tibia and ankle joint for malignancy. Methods: Retrospective review of all patients who underwent limb salvage with endoprosthetic reconstruction of the distal tibia and ankle joint at our institution. Data was collected from the bone tumour database, medical records, imaging studies, clinic reviews and individual structured patient questionnaires. MSTS and TESS scores were used to assess functional outcome. Results: Six patients underwent distal tibial replacement for malignant bone tumours of the distal tibia. There were 4 males and 2 females with a mean age of 31.2 years (range 13 to 68) and mean follow-up of 35 months (range 13 to 76). One patient died of non-neoplastic disease at 76 months. Two patients had Ewings sarcoma, two had osteosarcoma, one had malignant fibrous histiocytoma and one had adamantinoma. No patient had metastases at presentation and no patient developed local recurrence or distant metastases post-operatively. Four patients developed infection, for which two required below knee amputation and two suppressive antibiotics. Hardware failure was seen in one patient with infection which was managed by below knee amputation. One patient required sub-talar fusion and calcaneal osteotomy for persistent ankle pain. A child who underwent the procedure age 13 developed a 5 cm leg-length discrepancy once skeletally-mature. Mean MSTS and TESS scores for the three patients who still had a functioning endoprosthesis were 77% and 79% respectively. Conclusion: Limb salvage with distal tibial combined with ankle joint replacement can be used as an alternative to below knee amputation in patients with bone tumours of the distal tibia. Due to the difficulties in achieving adequate soft tissue cover, patients should be counselled regarding the high potential complication rate which can lead to significant morbidity, functional deficit and further surgical intervention

Introduction and Aims: I was presented with a Land-mine victim with closed fracture of right talus, compound injury to left lower limb, and defect in heelpad. Distal third of tibia and most of hindfoot were missing. Left foot neurovascularly intact and he was able to move his toes. Aim: reconstruct left distal tibia to enable full weight-bearing. Method: Lower leg debrided. LRS applied, using proximal ring with Sheffield clamp and two rings around foot. Corticotomy of proximal tibia. Bone transport, 10 days later. Heel debridement, to clear necrotic bone. Two months later transported bone was 2cm from ankle. Sepsis controlled. Distal tibia beveled, bone transport continued. Docking procedure performed. Ex-fix adjusted, attaining compression of hindfoot and midfoot. Distal tibia and foot transported 4cm, to correct disproportion. Osteoset used for bone growth. During the following two years, length discrepancy resolved, sepsis manageable. X-rays showed two cortices between proximal tibia and transported tibia. Fixator removed two months later. Received orthotic boot. Results: In September 2003 the patient came for follow-up. There was no evidence of sepsis in the leg. He was full weight-bearing using an orthotic shoe and rocker bottom sole. There was no pain. He had left the army and was now working as a builder in his country of origin and putting in a whole day’s work. The length of the transported segment is approximately 14cm. It is now fully consolidated and four cortices are visible on x-ray. The fusion of the distal tibia into the foot is solid and no pain is experienced from that. Conclusion: Big defects in the distal tibia can be managed with a straight rail reconstruction system, using unifocal bone transport with proximal corticotomy

Introduction. Posterior malleolar fractures are present in up to 44% of all ankle fractures. Those involving > 25% of the articular surface have a higher rate of posterior ankle instability which may predispose to post traumatic arthritis. The posterolateral approach to the distal tibia allows direct reduction and stabilization of the posterior malleolus and concomitant lateral malleolus fractures. An anatomical study was performed to establish the safe zone of proximal dissection to avoid injury to the peroneal vessels in this uncommon approach. Methods. 26 unpaired adult lower limbs were dissected using the posterolateral approach to the distal tibia as described by Tornetta et al. The peroneal artery was identified coursing through the intraosseous membrane on deep dissestion as the flexor hallucis longus muscle was reflected medially. The level of its bifurcation was also noted over the tibia. Perpendicular measurements were made from the tibial plafond to these variable anatomical locations. Results. The peroneal artery bifurcated at 83+/−21 mm (41–115mm) proximal to the tibial plafond and perforated through the interossoeus membrane 64+/−18 mm (47–96mm) proximal to the tibial plafond. Conclusion. The safe zone for the posterolateral approach to the distal tibia is described. Caution is advised as the bifurcation and perforating artery may be as little as 41mm from the tibial plafond. This is important during deep dissection when the belly of the flexor hallucis longus muscle is reflected medially from the medial edge of the fibula. Once the peroneal artery was mobilized a buttress plate could easily be placed beneath it

Purpose: Amputation is often proposed for malignant tumours of the distal tibia. The purpose of our study was to report outcome and complications after conservative treatment of osteosarcoma of the distal tibia. Material and methods: Eight patients, four boys and four girls aged 8 – 16 years (mean 12 years) were managed conservatively with high-dose methotrexate chemotherapy for osteosarcoma of the distal tibia between 1983 and 1998. Wide resection was performed in all cases and one patient had a lung metastasis. Mean length of resection was 13 cm (9–19). Tibiotalar reconstruction arthrodesis was performed in seven patients. Tibial grafts and a centromedullar nail associated with fibulotalar arthrodesis with screw fixation were used in four patients. Plate fixation was used in two, and one patient had a cement spacer while waiting for biological reconstruction. After surgery, the patients were immobilised in a plaster cast for three to six months. Weight bearing began two to four months after surgery. Results: Resection was wide in four cases, marginal in three , and contaminated in one. Four patients responded well to chemotherapy and four responded poorly. Outcome was assessed at a mean follow-up of 5.5 years (2–17 years). At last follow-up, six patients were in remission, and two had died, including one after local recurrence despite amputation. Three patients had a deep infection which cured in all three without surgery. Two revisions were required in one patient with nonunion before achieving a solid union. All the patients who had a tibiotalar arthrodesis progressively developed nearly normal “ankle” function subsequent to progressive sub-talar hypermobility. The mean MSTS score was 27.7/30 (range 22 – 30). Discussion: Conservative management of osteosarcoma of the distal tibia appears to be feasible and provides excellent functional results despite an important risk of infection. Wide surgical margins requires a good response to chemotherapy. In case of doubt, reconstruction must avoid contaminating the rest of the tibia in order to allow secondary amputation if needed

Distal tibia and ankle sepsis can threaten the viability of the limb. We present the management protocol and results in 37 patients with chronic infection of the distal tibia and ankle, followed up for a mean of 4 years. The mean age was 45.6 years. Host type A were 21 patients, type B were 9, and type C were 7 patients. Treatment included radical debridement, multiple cultures sampling and local antibiotic application. Twenty seven patients required bone stabilisation, whereas 3 host C patients were amputated. Soft tissue coverage included 5 free muscle flaps, 3 soleus flaps and 5 pedicle fasciocutaneous local flaps. Bone defects of a mean of 6.3 cm (3–13cm) in 20 cases were treated with distraction histogenesis (13 cases) or the free fibula vascularised graft (7 cases). Mean hospitalisation time was 26.2 days (host-A: 19.6 vs. host B/C: 32.2, p=0.036). Host-A patients required 2.3 operative procedures whereas host-B/C 3.9 (p=0.01). Union occurred in 26/27 (96%) of cases requiring fixation (one ankle arthrodesis revision/host-B patient). External fixation frames were kept in situ for a mean of 31.7 weeks (12–85). Mean leg length discrepancy was 0.6 cm. Ankle arthrodesis was performed in 7 patients (5% among host-A patients vs. 38% among B/C). Independent ambulation was achieved in (35/37) 95%. All patients were satisfied with the result. Bacteriology revealed Staph. aureus in 71%, whereas 38% were polymicrobial (7% in host-A vs. 88% in B/C patients, p< 0.001). Infection recurrence occurred in 5.4% (none in host-A vs. 13% in B/C patients, p=0.03), whereas the overall complication rate was 43% (24% in host-A vs. 75% in B/C patients, p=0.02). Functional limb salvage without leg length discrepancy was possible in 92% of cases. Systemically compromised patients required longer hospitalisation, more operative procedures, had frequently polymicrobial infections and more complications

We report the results of limb salvage for non-metastatic osteosarcoma of the distal tibia using resection arthrodesis, autogenous fibular graft and fixation by an Ilizarov external fixator. In six patients with primary osteosarcoma of the distal tibia who refused amputation, treatment with wide en bloc resection and tibiotalar arthrodesis was undertaken. The defect was reconstructed using non-vascularised free autogenous fibular strut graft in three patients and a vascularised pedicular fibular graft in three, all supplemented with iliac cancellous graft at the graft-host junction. An Ilizarov external fixator was used for stabilisation of the reconstruction. In five patients sound fusion occurred at a mean of 13.2 months (8 to 20) with no evidence of local recurrence or deep infection at final follow-up. The mean post-operative functional score was 70% (63% to 73%) according to the Musculoskeletal Tumour Society scoring system. All five patients showed graft hypertrophy. Union of the graft was faster in cases reconstructed by vascularised fibular grafts. One patient who had a poor response to pre-operative chemotherapy developed local tumour recurrence at one year post-operatively and required subsequent amputation

Fractures of distal tibia are common and often present with dilemma of appropriate and safe management. The use of locking plates has changed the way these fractures have been managed as it avoids extensive soft tissue dissection and periosteal stripping. The aims of this study were to look at the results of stabilization and analyse the complications of fractures of distal tibia treated with Locked plates. We carried out a retrospective study of patients who underwent surgical treatment for distal tibial fractures using MIPO (Minimally invasive Percutaneous Osteosynthesis) technique. The data was gathered from theatre data base. We studied a period between Nov 2006 to May 2009. We collected patient demographics as well as the type of fractures, mechanism of injury, radiological union and associated complications. There were no open fractures in the study. The limb was splinted for two weeks after surgery in a back slab. The patients were followed up at 6 weeks, 3, 6, 9 and 12 months after surgery. There were 45 patients in the study with 29 males & 16 females between ages of 20 – 87 (avg. 49 yrs). 24 patients sustained injury due to a fall, 12 were involved in RTA and the remaining 9 were sports related injuries. The mean time to surgery was 3.15 days (1 – 7) and surgery was carried either by the consultant or their direct supervision. The mean hospital stay was 7 days (2 – 35) and mean time to radiological evidence of callus was 9 weeks. All patients eventually returned to their preinjury employment. 76% showed radiological union at 6 months and 90% at 9 months. There were 3 superficial wound infections, 2 deep infections whilst 2 needed bone grafting and 1 implant failure. 2 patients developed mild form of CRPS which resolved at 12 months. 11 patients had metal discomfort of which 9 had removal of hardware. All these patients had the tip snapped off. MIPO with LCP is a reliable and reproducible technique in treatment of closed unstable fracture of distal tibia. Patients must be counselled about implant removal after fracture union. Avoid snapping the tip of the LCP

Wire crossing angle affects the stability of circular fine wire frames. Anatomical atlases document safe ‘corridors’ to avoid neurovascular structures, although this may limit crossing angle. In the distal tibia the furthest posteriolateral safe corridor described is through the fibula. The present study describes a new and safe ‘retro-fibular’ corridor for wire placement in the distal tibia that provides a greater crossing angle. Two different methods of wire insertion are considered to determine which provides greater protection to neurovascular structures. A dissection based study of 20 embalmed lower limbs divided into two groups. 1.8mm wires were inserted at increments along the tibia, from posterolateral to antero-medial, at 30–45 degrees to the sagittal plane. In the first group wires were placed against the posterior surface of the fibula and ‘stepped’ medially onto the tibia. In the second wires were inserted midway between the border of the fibula and tendoachilles. Standard dissection techniques were used to identify the path of wires and distance from neurovascular structures. In group one distal tibial wires avoided the posterior tibial neurovascular bundle (mean distance 21.7mm) although passed close to the peroneal artery (mean distance 1.2mm). In group two both the posterior tibial and peroneal structures were avoided (mean distances 15.5mm and 7.1mm respectively). Comparison of the two groups shows a significant difference (p< 0.001). Retrofibular wire placement is safe in the distal quarter of the tibia and facilitates an optimal crossing angle, although is not described in standard atlases. Insertion of wires mid-way between the posteromedial border of the fibula and the tendoachilles appears the most reliable technique

Aim. The aim of this study was to compare the cost-effectiveness of intramedullary nail fixation and ‘locking’ plate fixation in the treatment of extra-articular fractures of the distal tibia. Patients and Methods. An economic evaluation was conducted from the perspective of the United Kingdom National Health Service (NHS) and personal social services (PSS), based on evidence from the Fixation of Distal Tibia Fractures (UK FixDT) multicentre parallel trial. Data from 321 patients were available for analysis. Costs were collected prospectively over the 12-month follow-up period using trial case report forms and participant-completed questionnaires. Cost-effectiveness was reported in terms of incremental cost per quality adjusted life year (QALY) gained, and net monetary benefit. Sensitivity analyses were conducted to test the robustness of cost-effectiveness estimates. Results. Mean NHS and PSS costs were significantly lower for patients treated with an intramedullary nail than for those treated with a locking plate (-£970, 95% confidence interval (CI) -1685 to -256; p = 0.05). There was a small increase in QALYs gained in the nail fixation group (0.01, 95% CI -0.03 to 0.06; p = 0.52). The probability of cost-effectiveness for nail fixation exceeded 90% at cost-effectiveness thresholds as low as £15 000 per additional QALY. The cost-effectiveness results remained robust to several sensitivity analyses. Conclusion. This trial-based economic evaluation suggests that nail fixation is a cost-effective alternative to locking plate fixation. Cite this article: Bone Joint J 2018;100-B:624–33

Introduction: An important factor affecting the stability of circular fine wire frames is the wire crossing angle, where an angle of 90 degrees confers optimal stability. Safe anatomical ‘corridors’ have been described to avoid neurovascular structures, but often limit the crossing angle. In the distal tibia the posterior tibial artery and tibial nerve wind medially facilitating safe placement of a posterior to anterior ‘retrofibular’ wire. The present study aims to identify structures at risk during ‘retrofibular’ wire placement and determine the level at which this can be used safely. Methods: A dissection based study of 10 embalmed lower limbs. Wires of 1.8mm diameter were inserted at increments along the tibia. These were placed against the posterior surface of the fibula and ‘stepped’ medially past the posteromedial border onto the tibia. Wires were introduced from posterior to anterior, between 30 degrees and 45 degrees to the sagittal plane. This angle is estimated, reproducing clinical practice. Standard dissection techniques were used to identify the path of wires and distance from neurovascular structures. Results: In the distal quarter of the tibia wires avoided the posterior tibial neurovascular bundle (mean distance 21.7mm) although passed close to the peroneal artery (mean distance 1.2 mm). Of the 30 wires placed in the distal tibia, 29 (97%) passed through the leg without damage to any neurovascular structures. Anterior tendons were tethered by 13% of wires placed in the distal quarter of the tibia. Discussion: Retrofibular wire placement facilitates an optimal crossing angle, although is not described in standard atlases. Use in the lower quarter of the tibia does not threaten the posterior tibial neurovascular bundle. However, peroneal artery injury is a possibility. The clinical significance of peroneal artery injury at this level is unclear but should be considered when using this technique

Most high-energy trauma to lower legs, ankles and feet result in severe crush injuries. We performed a retrospective case series study. Eight patients (7M: 1F) with mean age of 28 years (range -18 -35 years) were included. Four had Grade 3 open fractures of the distal tibia and 5 had open foot fractures. Two had neurovascular injuries. Four patients had associated injuries with mean ISS of 9 (range 8-16) and a mean MESS score of 3.5 (3-7). All had undergone some form of internal and external fixation within approximately 24 hours (8 hrs to 4 days). The mean follow-up period was two years (range 1-4 years). At final follow-up patients' health was measured using SF-36 questionnaire. Six patients had their fractures healed at a mean of 4.8 months (4-9 m). Two patients had fully functional foot with occasional complaints of painful ankle. Two patients had CRPS1 undergoing treatment. Two patients are unable to walk due to chronic pain and deformity. Comparison of the SF-36 scores with the age-matched UK normal controls without foot and ankle injuries showed significantly worse scores in physical function (PF: p<0.01) and role physical (RP: p< 0.01) categories. Our surgical instinct dominates decision-making, favouring salvage rather than amputation in these young groups of patient. They gradually suffer a cocktail of crippling disease characterised by psycho-socio-economic and physical disability. Should we be depleting our resources in salvaging these complex limb injuries?

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

A series of 3061 patients with fracture of the distal tibia or ankle was studied for a possible link between overweight and failed reduction. The relative body-weight was recorded as the preoperative self-reported body mass index (BMI) of each patient. There were 109 patients (3.6%) with failure of internal fixation or of closed reduction severe enough to necessitate refixation or corrective osteotomy. The mean BMI in all age- and gender-specific groups studied was found to be significantly higher in patients with failed reduction than in those with an uneventful course (p < 0.01). The relative risk of loss of reduction for patients with a BMI greater than 1SD above the BMI of the corresponding age and gender group of the general population was 3.72 for distal tibial fractures and 3.04 for ankle fractures. Overweight should be recognised as a significant factor in predicting a complicated course after a fracture of the lower leg. Awareness of the increased risk of loss of reduction in overweight patients is important in all phases of management

Surgical treatment of distal tibia fractures is usually associated with extensive soft tissue compromise and high complication rates (infection, delayed or non-union, ankle stiffness and osteoarthritis). Wound infection is one of the most common complication (deep infection rates up to 15%) and can develop into an infected non-union. In 1973, Papineau described a staged technique for treating infected non-union of long bones, consisting of (1) surgical debridement of necrotic tissue, temporary splinting, specific antibiotic treatment, postoperative wet-to-dry wound dressing changes; (2) packing of the bone defect with cortico-cancellous autograft; (3) closure of the soft-tissue wound by a flap or secondary intent. The authors aim to report a clinical case of a successful treatment of a distal tibia infected non-union with the Papineau technique and negative-pressure wound therapy. Woman, 56 years-old, referred to Orthopaedic consultation on October 2013 for wound dehiscence and infection with a methicillin-resistant Staphylococcus aureus, one month after open reduction and internal fixation of an open distal tibia fracture. On November 2013 she underwent surgical debridement, removal of osteosynthesis material, osteotaxis with external fixator, negative-pressure wound therapy and antibiotic treatment with intravenous vancomycin 1g 12/12h (1st stage of Papineau procedure). On December, she underwent autologous iliac crest cancellous bone grafting and wound care, daily irrigated with saline solution (2nd stage). On February 2014, she underwent a partial thickness skin graft for wound closure (3rd stage). On April, the external fixator was removed and there was still no evidence of union. She had pain, disuse osteoporosis, ankle and midfoot stiffness, and was sent to physical therapy. On April 2015, she can full weight bear with mild pain, the soft tissue envelope is in good condition, the fracture has united and she has an Ankle AOFAS Score of 83. The Papineau technique has been used for the management of infected non-unions with bony defects, with high success rates. Complete necrotic tissue debridement and targeted antibiotics are fundamental for obtaining a viable and healthy tissue, able to receive the bone graft. Negative-pressure wound therapy is important in reducing the bacterial load, improving the microcirculation and enhancing the granulation tissue. In the present case, the combination of the two techniques probably acted together in achieving successful eradication of the infection, reconstruction of the bone defect and soft tissue closure

Distal tibial bone loss involving the ankle is a devastating injury with few options for reconstruction. The purpose of our study was to look at the long term results of ilizarov technique used to achieve lengthening of tibia and fusion at the ankle. 17 cases (16 post traumatic and one post tumor resection) admitted to one institution between 1994 and 2003. 13 cases were done in bifocal and four in trifocal mode. The duration of follow up was 12 to 84 months The average age was 33 years (Range 7–71). The mean length of the defect was 4.5 cm (Range 1–12). Union of the fusion site occurred in 88% (15/17) of the patients with mean duration to docking and union being 8 months. The mean time in fixator was 13 months (Range 5 to 29). Average number of surgeries per patient was 3.2. Five patients required free vascularised grafts before the index procedure and 4 patients required realignment at the docking site. Functional results – Fourteen (77.5%) of the patients could walk without support or bracing and twelve patients (71%) returned to same or modified occupation. Complications – Two non-union. Deformity – Fusion site equinus deformity occurred with non union after re-fracture in one case. There were 2 cases of residual fore-foot equinus. Residual low grade infection with discharging sinus was present in two patients. One patient needed change of wires for Pin tract infection. Our study showed 76% good and excellent scores on functional scoring but also demonstrates the high morbidity associated with this procedure. In spite of the steep learning curve and high complication rates the procedure can be undertaken in specialised centers for highly motivated patients to achieve good functional results

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

Aims: Nonunions of the distal tibia are difþcult to treat due to the short distal segment, the proximity to the ankle joint and the fragile soft tissue envelope. Intramedullary nailing is an attractive solution as it avoids extensive soft tissue dissection and remains intraosseus, posing little problem for the soft tissues. The purpose of this study was to determine the efþcacy of reamed intramedullary nailing in the treatment of non-unions of the distal one-quarter of the tibia. Methods: Thirty-two patients with nonunions of the distal one-quarter of the tibia were treated by reamed, locked intramedullary nailing. Prior treatments included casting as well as intramedullary or extramedullary þxation techniques. No patient had signs of an active infection at the time of surgery. Time to union, correction of deformity and complications including infection and reoperation were examined. Results: Twenty-nine out of thirty-two patients achieved union at an average of 3.5 months after surgery. Of the remaining three, two patients united rapidly after dynamisation and one after exchange nailing. Deformity was corrected to a maximum of four degrees in all planes. Four patients had positive intraoperative culture, and only two required removal of the nail after achieving union to eradicate infection. There were no cases of chronic osteomyelitis after the procedure. Conclusions: Reamed, locked intramedullary nailing is a reliable and safe procedure in the treatment of nonunions in the distal one-quarter of the tibia. It allows for excellent correction of deformity, which is an essential component of the procedure

We have reviewed 15 cases of triplane fracture of the distal tibia. The mechanism of injury is lateral rotation and the anatomical pattern of the fracture depends on the state of the growth plate at the time of injury. In seven of our cases the anteromedial part of the growth plate was fused, but in eight children the plate was completely open. In six of these eight children there was a hump or projection of the medial growth plate. It is suggested that this hump stabilises the anteromedial part of the epiphysis in a manner similar to the partial anteromedial fusion seen in older children, and that this accounts for the occurrence of triplane fracture in the presence of an open growth plate

Fractures of the distal tibia metaphysis comprise a challenge for the orthopaedic trauma surgeon because of the poor blood irrigation they do not heal very easy leading sometimes to pseudarthrosis and many times arise problems with the skin. We compare the following techniques: LC-DCP and LCP plates, MIPO, External fixators (hybrids or simple one), intramedullary nailing with multiple screws at the distal end. 94 cases of distal tibia fractures from all AO types were treated during last 3 years (2005–2008) with the following techniques:. 16 ORIF with LC-DCP plates. 9 ORIF with LCP plates. 19 MIPO. 35 External fixators. 15 intramedullary nailing. The simple oblique or spiral fractures which treated with the 1st and 2nd method (ORIF), they do not seem any remarkable difference in healing but both methods demonstrate a delay in fracture healing over 5 months. The 3rd method display faster healing 2,5 months average in simple fractures with no skin wound at all. The 4th method display 3 pin track infections and dealt with removal of the material and 2 pseudarthrosis which encountered with ORIF and bone grafting from the iliac. The 5th method display 2 malunions but because of the small angle in varus we do not perform any treatment. Every technique has its own position on those type of fractures, depending of the personality of the fracture and the skill of the surgeon

Percutaneous plating of the distal tibia via a limited incision is an accepted technique of osteosynthesis for extra-articular and simple intra-articular distal tibia fractures. In this study we identify structures are risk during this approach. Method. Thirteen unpaired adult lower limbs were used for this study. Thirteen, 16-hole synthes®LCP anterolateral distal tibial plates were percutaneously inserted according to the manufacturer instructions and confirmed by xray. Dissection was performed around the plate to examine the relation of nerves and soft tissue. Results. The neurovascular bundle was under the plate in one case. Over the horizontal limb of the plate, typically the superficial peroneal nerve had a variable course over all four screw holes. The anterior tibial artery coursed over hole number 3 and the Extensor hallucis longistendon was positioned over hole 3 or 4. The Anterior tibialis tendon skirted hole 4 in 12 cases. Over the vertical limb of the plate, the neurovascular bundle coursed over holes, 5 to 7, the superficial peroneal nerve over holes 5 to 7. Discussion. Meticulous attention is required when placing an anterolateral distal tibia plate using a MIPO technique. We recommend a larger initial incision to avoid entanglement of the superficial peroneal nerve under the plate. Over the anterior aspect of the tibia, an open technique with adequate neurovascular structure and tendon protection is necessary due to the variability of structure coursing over the plate. A bridging technique for placement of proximal locking screw should be made through a mini open incision and this is safe to do so proximally over holes 12 to 16. Caution is advised during placement of screws percutaneously from holes 1 to 12 however the neurovascular bundle courses commonly over holes 5 to 7. These landmarks also apply to the use of shorter anterolateral distal tibial plates

This study identified imaging parameter(s) which best predict the mechanical properties of distal tibia. Seventeen human cadaver tibiae were assessed by PQCT at four, eight and ten percent site from distal and tested in compression at the twenty-five percent distal portion. Ultimate compressive loads were recorded with a mean of 8276 ± 2915 N. Spearson rank correlation and stepwise regression analysis revealed that CoA, total BMC, SSI and SSI4-TrA4-CoD4 combination had statistically significant correlations with the failure loads. Among all imaging parameters, SSI had the highest relevance due to its account for geometry, density and material distribution, important factors for structural properties. Musculoskeletal diseases, especially hip fractures, have huge and growing impact on Canadian society. To develop techniques for identification of high risk population, we needed a link between clinical evaluations and laboratory measures of bone health. This study identified imaging parameter(s) which best predict the mechanical properties of distal tibia. Seventeen human cadaver tibiae were considered in this study (mean age seventy-four, SD six years). PQCT was used to assess the four, eight and ten percent site. It measured the cross-sectional area, bone mineral content and bone mineral density of the cortical bone, trabecular bone and combined. Strength Strain Index (SSI) was calculated from these measurements. Each tibia was cut at twenty-five percent distal. Compressive force was applied uniaxially through a custom-made PMMA indentor onto the distal plateau along the longitudinal axis of the tibia at a rate of 10mm/s. Load and displacement data were recorded. Spearson rank correlation and stepwise regression analysis were used to identify individual and combination of imaging variables that were related to ultimate failure load. Ultimate failure loads were recorded with a mean of 8276 ± 2915 N. Cortical area (R_0.72), total BMC (R_0.72) and SSI (R_0.86) had statistically significant correlations with the failure load. Stepwise regression revealed that the combination of SSI, TrA, CoD at 4% site explained the greatest amount of variance (R2 = 0.868) and SSI was the major contributor. SSI takes the polar moment of inertia (geometry), density and distribution of material into account. This explains its relevance towards predicting the ultimate failure load.

Unstable fractures of the distal tibia are being increasingly treated by open reduction and internal fixation using pre-contoured locking plates. Functional outcome following this type of fixation has not been reported previously. The aim of this study was to functionally assess patients following MIPO fixation of distal tibial fractures. Case notes of 26 patients treated at a single centre were reviewed. The fracture type, fixation technique, complications, time to union and subsequent treatment were documented. All patients returned for functional scoring using the validated American Academy of Orthopedic Surgeons (AAOS) foot and ankle core score. Twenty-six consecutive patients were treated between 2002-2005. The majority were male, and 5 were open fractures. There were 13 AO type A, 4 type B and 9 type C fractures. Mean follow up was 20 months. Average time from injury to surgery was 2.5 days. All fractures were treated by a MIPO technique. A pre-contoured distal locking plate was used for the distal tibial reconstruction. Secondary surgical procedures e.g. 2nd look, delayed primary closure, or skin grafting were necessary in 3 cases. The fibula was plated in 60% of cases. Four patients developed wound infections requiring antibiotics, and all resolved. The commonest rehabilitation regime was 6 weeks non weight bearing in plaster. Mean time to union was 18 weeks. There were 3 cases of delayed union, requiring bone grafting. One patient required removal of the plate due to local irritation, and one required a broken screw to be removed. Mean range of movement was 10 degrees dorsiflexion, 30 plantarflexion. The mean normalised AAOS foot and ankle core score was 41 (SD +/− 8). We conclude that MIPO fixation of distal tibial fractures is a safe and effective method of treatment. Functional outcome does not significantly differ from that of the general population

The treatment of high energy fractures of distal tibia by internal fixation is followed by a high rate of soft tissue complications. The result estimation of these fractures in a two stage treatment, bridging the ankle by Ex-Fix with/without internal fixation of the fibula and internal fixation of the tibia after soft tissue recovery. In a 4 year period (2005–8), 15 patients, average of 42 years were treated. The AO fracture classification was followed. The soft tissue damage estimation (Osternn-Tscherne and Gustillo classification), the fracture pattern of the fibula and the injury mechanism consisted of the choice method criteria. The majority of the injuries was classified Tscherne II & III, and 3 open fractures Gustillo II. Fracture reduction was performed by bridging Ex-Fix of the ankle with/without plating the fibula with a 1/3 or DCP 3.5 mm plate. Definite internal fixation of the tibia by locking plate was performed from 8th –14th postoperative day after soft tissue recovery. Preoperatively CT scan was performed with grate significance, defining the soft tissue condition, the surgical approach and the osteosynthesis type. Follow up average 14 months. None of the patients developed infection. All wounds were healed in one stage. Superficial skin necrosis was conservatively treated in two patients. Soft tissue complications, after internal fixation of high energy fractures of the distal tibial, usually appear. Two stages treatment allows better preoperative planning, immediate patient mobilization and reduce complication rate

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

Salter-Harris II fractures of the distal tibia affect children frequently, and when they are displaced present a treatment dilemma. Treatment primarily aims to restore alignment and prevent premature physeal closure, as this can lead to angular deformity, limb length difference, or both. Current literature is of poor methodological quality and is contradictory as to whether conservative or surgical management is superior in avoiding complications and adverse outcomes. A state of clinical equipoise exists regarding whether displaced distal tibial Salter-Harris II fractures in children should be treated with surgery to achieve anatomical reduction, or whether cast treatment alone will lead to a satisfactory outcome. Systematic review and meta-analysis has concluded that high-quality prospective multicentre research is needed to answer this question. The Outcomes of Displaced Distal tibial fractures: Surgery Or Casts in KidS (ODD SOCKS) trial, funded by the National Institute for Health and Care Research, aims to provide this high-quality research in order to answer this question, which has been identified as a top-five research priority by the British Society for Children’s Orthopaedic Surgery.

Distal tibial bone loss involving the ankle is a devastating injury with few options for reconstruction. The purpose of our study was to look at the long term results of ilizarov technique used to achieve lengthening of tibia and fusion at the ankle. 17 cases (16 post traumatic and one post tumor resection) admitted to one institution between 1994 and 2003. 13 cases were done in bifocal and four in trifocal mode. The duration of follow up was 12 to 84 months The average age was 33 years (Range 7-71). The mean length of the defect was 4.5 cm (Range 1-12). Union of the fusion site occurred in 88 % (15/17) of the patients with mean duration to docking and union being 8 months. The mean time in fixator was 13 months (Range 5 to 29). Average number of surgeries per patient was 3.2. Five patients required free vascularised grafts before the index procedure and 4 patients required realignment at the docking site. Functional results – Fourteen (77.5%) of the patients could walk without support or bracing and twelve patients (71%) returned to same or modified occupation. Complications – Two non-union. Deformity – Fusion site equinus deformity occurred with non union after re-fracture in one case. There were 2 cases of residual fore-foot equinus. Residual low grade infection with discharging sinus was present in two patients. One patient needed change of wires for Pin tract infection. Our study showed 76% good and excellent scores on functional scoring but also demonstrates the high morbidity associated with this procedure. In spite of the steep learning curve and high complication rates the procedure can be undertaken in specialised centres for highly motivated patients to achieve good functional results

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

Purpose: To evaluate the outcome of salvage surgery with external fixation in these rare and severe lower limb injuries. Methods: Eight patients (7M: 1F) with mean age of 28 years (range −18 −35 years) were included. Four had Grade 3 open fractures of the distal tibia and 5 had open foot fractures. Two had neurovascular injuries. Four patients had associated injuries with mean ISS of 9 (range 8–16) and a mean MESS score of 3.5 (3–7). All had undergone some form of internal and external fixation within approximately 24 hours (8 hrs to 4 days). The mean follow up period was two years (range 1 – 4 years). At final follow-up patient’s health was measured using SF-36 questionnaire. Results: Six patients had their fractures healed at a mean of 4.8 months (4–9 m). Two patients had fully functional foot with occasional complaints of painful ankle. Two patients had CRPS1 undergoing treatment. Two patients are unable to walk due to chronic pain and deformity. Comparison of the SF -36 scores with the age-matched UK normal controls without foot and ankle injuries showed significantly worse scores in physical function (PF: p< 0.01) and role physical (RP: p< 0.01) categories. Conclusions: Our surgical instinct dominates the decision-making favoring salvage with external fixation primarily rather than amputation in these young groups of patient. Should we be depleting our resources in salvaging these complex limb injuries?

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.

The aim of this study was to evaluate the results of a consecutive series of distal tibial fractures treated by percutaneous plating.

85 patients with distal tibial fractures were treated using minimally invasive medial plate fixation. 18 patients had open fractures. Eight had displaced intra-articular fractures (AO type 43C). The majority had extra-articular fractures (AO type 42 or 43A). Patients ranged in age from 16–89 years. All were followed to union with a minimum follow-up period of 6 months (average 47 months). Outcome measures assessed retrospectively were alignment, time to full weight bearing and complications including infection, delayed or non-union and secondary surgery.

The mean time to surgery after injury was 5 days (range 0–22). 51 patients had unlocked pre-contoured plates and the remaining 34 had locking plates. The fibula was plated in 41 cases. Post-operative mal-alignment greater than 5 degrees varus or valgus occurred in 3 cases (3.5%). The average time to full weight bearing was 11 weeks. Superficial infection occurred in 6 patients (7%) and deep infections in 4 cases (4.7%). There was one case of plate fracture. 4 patients, including this case, required further surgery to achieve union. There was a high rate of metalware symptoms that prompted plate removal.

Percutaneous plate fixation of distal tibial fractures is a reliable method of treatment with complication rates lower than reported for open techniques.

Aim: The aim of this study was to compare the treatment results of distal tibia shaft fractures treated with intramedullary nails with two different distal lockings and medial locking plates. Patients and Method: Sixty-four patients with distal tibia fractures (4 to 11 cm proximal to the plafond) were operated with either unreamed intramedullary nails with medio-lateral distal locking (group A) or unreamed intra-medullary nails with both medio-lateral and antero-posterior lockings (group B), or medial locking plates (group C). There were 22 patients in group A, 22 patients in group B and 20 patients in group C. Mean age was 48.53±17.07 years. Mean follow-up was 26.68±7.02 months. At latest follow-up groups were compared for union time, malunion (defined as more than 5 degrees of angulation in any planes and/or any rotation and/or more than 5 milimeters of shortening), and delayed (lack of healing within 3 months) or nonunion (lack of healing within 6 months). Uninon was defined as healing of at least three of four cortices on AP and lateral radiographs. Results: Mean union time was 17.45±4.22 weeks in group A, 16.71±4.90 weeks in group B and 15.73±3.26 weeks in group C. There was no significant difference between groups regarding union time. (p> 0.05) Malunion as defined was dedected in 4 patients in group A, in 4 patients in group B and in 1 patient in group C. There was no significant difference between groups regarding malunion rates. (p> 0.05). Delayed or non union was dedected in 6 patients in group A, in 5 patients in group B and in 1 patient in group C. There was no significant difference between groups regarding delayed or non-union. (p> 0.05). Two nonunions in group A and one nonunion in group B had to be treated with exchance reamed nailing. One infected nonunion in group C had to be treated with circular external fixation. Conclusions: The results of surgical treatment of distal tibia fractures are similar with these three diifferent methods. Although malunion and delayed or nonunion rates are lower with medial locking plates, this is not significant

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.

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.

Osteoid osteoma is a benign bone-forming lesion, characterized by its small size, its clearly demarcated outline and by the usual presence of a surrounding zone of reactive bone formation. It often poses a diagnostic challenge due to its ambiguous presentation. The aetiology of osteoid osteoma is poorly understood. The previous suggestion that osteoid osteoma was not associated with trauma or infection has been challenged by more recent literature raising the possibility that it could be a reactive or healing response or a phenomenon associated with the revascularisation process. This case report describes an unusual presentation of a post-traumatic osteoid osteoma. Two years following a diaphyseal, spiral tibial fracture treated nonoperatively, the patient developed new pain at the previous fracture site. The pain was constant, relieved by non-steroidal analgesia and not associated with systemic upset. It was initially attributed to other more likely diagnoses such as osteomyelitis and neuropathic pain. Multiple investigations and interventions were undertaken prior to the definitive diagnosis being obtained by surgical excision of the lesion and histological studies five years after the injury and three years following the initiation of the discomfort. In both English and foreign language literature there are only seven case reports that document osteoid osteoma following fracture, these are predominantly in the lower limb with no predominance to operative or nonoperative management. This case report should raise the index of clinical suspicion of osteoid osteoma occurring post fracture.

Background

Distal tibial metaphyseal fractures pose many complexities. This study assessed the outcomes of distal tibial fractures treated with percutaneously inserted medial locking plates.

This is an outcome study of the use of plate fixation for treatment of comminuted fractures of the distal third of tibia to determine prognostic factors such as age, sex, type of fractures, soft tissue injury and type of implant on healing.

Since 1999, a single surgeon (VP) has performed minimally invasive fixation in 18 patients for complex transitional fractures of the tibia. Follow up has been achieved by a combination of clinical and radiological assessment and notes review.

An overall excellent-good result was obtained in 17 of 18 patients. In one patient, the fixation was revised due to a 20 degree external rotation mal position. In two cases there was mild external rotation of 10 degrees. There were no infections.

The treatment of difficult juxta-articular fractures with a minimally invasive fixation is a useful management option. Peri-articular plates are easy to insert and give better results with respect to alignment correction.

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.

Aims

The aim of this study was to determine the immediate post-fixation stability of a distal tibial fracture fixed with an intramedullary nail using a biomechanical model. This was used as a surrogate for immediate weight-bearing postoperatively. The goal was to help inform postoperative protocols.
