Introduction and Objective. Intramedullary nails are frequently used for treatment of unstable distal tibia fractures. However, insufficient fixation of the distal fragment could result in delayed healing, malunion or nonunion. The quality of fixation may be adversely affected by the design of both the nail and locking screws, as well as by the fracture pattern and bone density. Recently, a novel concept for angular stable nailing has been developed that maintains the principle of relative stability and introduces improvements expected to reduce nail toggling, screw migration and secondary loss of reduction. It incorporates polyether ether ketone (PEEK) inlays integrated in the distal and proximal canal portions of the nail for angular stable screw locking. The nail can be used with new standard locking screws and low-profile retaining locking screws, both designed to enhance cortical fixation. The low-profile screws are with threaded head, anchoring in the bone and increasing the surface contact area due to the head's increased diameter. The objective of this study was to investigate the biomechanical competence of the novel angular stable intramedullary nail concept for treatment of unstable distal tibia fractures, compared with four other nail designs in an artificial bone model under dynamic loading. Materials and Methods. The distal 70 mm of thirty artificial tibiae (Synbone) were assigned to 5 groups for distal locking using either four different commercially available nails – group 1: Expert Tibia Nail (DePuy Synthes); group 2: TRIGEN META-NAIL with Internal Hex Captured Screws (Smith & Nephew); group 3: T2 Alpha with Locking Screws (Stryker); group 4: Natural Nail System featuring StabiliZe Technology (Zimmer) – or the novel angular stable TN-Advanced nail with low-profile screws (group 5, DePuy Synthes). The distal locking in all groups was performed using 2 mediolateral screws. All specimens were biomechanically tested under quasi-static and progressively increasing combined cyclic axial and torsional loading in internal rotation until failure, with monitoring by means of motion tracking. Results. Initial nail toggling of the distal tibia fragment in group 5 was significantly lower as compared with group 3 in varus (p=0.04) or with groups 2 and 4 in flexion (p≤0.02). In addition, the toggling in varus was significantly lower in group 1 versus group 4 (p<0.01). Moreover, during dynamic loading, within the course of the first 10,000 cycles the movements of the distal fragment in terms of varus, flexion, internal rotation, as well as axial and shear displacements at the fracture site, were all significantly lower in group 5 compared with group 4 (p<0.01). Additionally, group 5 demonstrated significantly lower values for flexion versus groups 2 and 3 (p≤0.04), for internal rotation versus group 1 (p=0.03), and for axial displacement versus group 3 (p=0.03). A trend to significantly lower values was detected in group 5 versus group 1 for varus, flexion and shear displacement – with p ranging between 0.05 and 0.07 – and versus group 3 for shear displacement (p=0.07). Cycles to failure were highest in group 5 with a significant difference to group 4 (p<0.01). Conclusions. From a biomechanical perspective, the novel angular stable intramedullary nail concept with integrated PEEK inlays and low-profile screws provides ameliorated resistance against nail toggling and loss of reduction under static and dynamic loading compared with other commercially available intramedullary nails used for fixation of unstable distal tibia fractures

Unstable distal tibia fractures are challenging injuries requiring surgical treatment. Intramedullary nails are frequently used; however, distal fragment fixation problems may arise, leading to delayed healing, malunion or nonunion. Recently, a novel angle-stable locking nail design has been developed that maintains the principle of relative construct stability, but introduces improvements expected to reduce nail toggling, screw migration and secondary loss of reduction, without the requirement for additional intraoperative procedures. The aim of this study was to investigate the biomechanical competence of a novel angle-stable intramedullary nail concept for treatment of unstable distal tibia fractures, compared to a conventional nail in a human cadaveric model under dynamic loading. Ten pairs of fresh-frozen human cadaveric tibiae with a simulated AO/OTA 42-A3.1 fracture were assigned to 2 groups for reamed intramedullary nailing using either a conventional (non-angle-stable) Expert Tibia Nail with 3 distal screws (Group 1) or the novel Tibia Nail Advanced system with 2 distal angle-stable locking low-profile screws (Group 2). The specimens were biomechanically tested under conditions including quasi-static and progressively increasing combined cyclic axial and torsional loading in internal rotation until failure of the bone-implant construct, with monitoring by means of motion tracking. Initial axial construct stiffness, although being higher in Group 2, did not significantly differ between the 2 nail systems, p=0.29. In contrast, initial torsional construct stiffness was significantly higher in Group 2 compared to Group 1, p=0.04. Initial nail toggling of the distal tibia fragment in varus and flexion was lower in Group 2 compared to Group 1, being significant in flexion, p=0.91 and p=0.03, respectively. After 5000 cycles, interfragmentary movements in terms of varus, flexion, internal rotation, axial displacement and shear displacement at the fracture site were all lower in Group 2 compared to Group 1, with flexion and shear displacement being significant, p=0.14, p=0.04, p=0.25, p=0.11 and p=0.04, respectively. Cycles to failure until both interfragmentary 5° varus and 5° flexion were significantly higher in Group 2 compared to Group 1, p=0.04. From a biomechanical perspective, the novel angle-stable intramedullary nail concept has the potential of achieving a higher initial axial and torsional relative stability and maintaining it with a better resistance towards loss of reduction under dynamic loading, while reducing the number of distal locking screws, compared to conventional locking in intramedullary nailed unstable distal tibia fractures

Introduction. Minimally invasive plate osteosynthesis (MIPO) is a relatively new surgical technique for the management of distal tibial fractures. Conventional open technique is unfavourable to the fracture biology because of excessive soft tissue stripping and can be associated with significant devastating complications. Objective. The aim of this study was to determine the effectiveness of the MIPO technique for distal tibial fractures. Methods. Between 2004 and 2010 twenty-nine consecutive patients had distal tibial fractures treated with MIPO by the senior author. An anteromedial plate (Synthes®) was used for all patients. Case notes and radiographs of all patients were reviewed and data, including demographics, fracture classification, complications and fracture healing were recorded on a database. Results. 29 Patients with a median age of 46 (range 25–82) were reviewed. 12 were female and 17 were male. Mean follow-up was 6.24 months. Using the AO classification there were 16 type A, 1 type B and 12 were type C fractures. Ruedi-Allgower classification showed 6 Group I fractures, 5 Group II fractures and 2 Group III fractures. There were no open fractures. 5 patients had temporary external fixation prior to MIPO. 28 patients had associated fibular fractures of which 6 required open reduction and internal fixation (through a separate surgical incision). There were no postoperative wound complications. No malunion or intraarticular displacement was noted radiographically. Two patients had delayed union but went on to heal without secondary procedures. There was 1 case of non-union. Two patients subsequently had their plates removed due to prominence of the metal work. Conclusion. We conclude that the MIPO technique is safe and effective treatment for the management of distal tibial fractures. Complications associated with MIPO are infrequent and manageable

Introduction. Distal tibial fractures are notoriously difficult to treat and a lack of consensus remains on the best approach. This study examined clinical and functional outcomes in such patients treated definitively by circular external fixation (Ilizarov). Patients and Methods: Between July 2011 and May 2016, patients with fractures extending to within 1 muller square of the ankle were identified from our prospective Ilizarov database. Existing data was supplemented by review of clinical records. Fractures were classified according to the AO/OTA classification. Functional outcome data, including general measures of health related quality of life (SF-12 and Euroqol) and limb specific scores (Olerud and Molander Score and Lysholm scores) had been routinely collected for part of the study period. Patients in whom this had not been collected were asked to complete these by post. Adverse events were documented according to Paley's classification of: problems, obstacles and complications. Results. 142 patients with 143 fractures were identified, 40 (28%) were open, 94 (66%) were intra-articular, 85 (59%) were tertiary referrals. 32% were type 1, 28%, type 2 and 40% type 3 AO/OTA severity. 139 (97%) of the fractures united (2 non-unions, 1 amputation and 2 delayed unions who remain in frames), at a median of 165 days (range 104 to 429, IQR 136 to 201). 62% united by 6 months, 87% by 9 months and 94% by 1 year. Both non-unions have united with further treatment. Closed fractures united more rapidly than open (median 157 vs 185 days; p=0.003) and true Pilon (43C3) fractures took longer to unite other fractures (median 156 vs 190 days; p<0.001). 34% of patients encountered a problem, 12% an obstacle and 10% a complication. Of the complications, 6 (4%) were minor, 5 (3.5%) major not interfering with the goals of treatment and 4 (3%) major interfering with treatment goals (including the 2 patients with non-union and 1 who underwent amputation as well as 1 significant mal-union). This will increase to 4% if the 2 delayed unions fail to unite. Overall 56% reported good or excellent ankle scores at last report, 28% fair and 16% poor. Closed, extra-articular and non-43C3 fractures had better functional outcome scores than open, intra-articular and 43C3 fractures respectively. Conclusions. This study demonstrates a high union and low serious complication rate, suggesting that external ring fixation is a safe and effective treatment for these injuries. *Judged best paper*

Aims

To describe outcome reporting variation and trends in non-pharmacological randomized clinical trials (RCTs) of distal tibia and/or ankle fractures.

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.

The surgical care of extra-articular distal tibial fractures remains controversial. This study looks at the radiological outcomes of distal tibial fractures treated with either a direct medial or anterolateral plate, with or without plating of the fibula, to assess the outcome and complications associated with these 2 approaches. This is a retrospective review of 80 patients with distal tibial extra-articular fractures, treated with an open reduction and plating, between 2008 and 2019 at Glasgow Royal Infirmary. Case notes and x-rays were reviewed. Of those tibial fractures fixed with only a medial plate, 78% united (28/36), 5% (2/36) had a non-union and 17% (6/36) a malunion. In the group treated with a combination of medial tibial and fibular plating, the figures were; 71% (15/21), 19% (4/21) and 10% (2/21). However, in the group treated with anterolateral plating of the tibia alone, only 53% (8/15) united, with a 20% (3/15) non-union and 13% (2/15) malunion rate. Additionally in this group, there were 2 patients (13%) with loss of fracture reduction within the first two months of fracture fixation, requiring revision surgery. Interestingly, of the 8 patients treated with anterolateral tibial and fibular plating, 88% (7/8) showed full union and only one (12%) had a non-union, with no malunions is this group. It would appear that medial tibial and a combination of medial tibial and fibular plating, have superior outcomes compared to anterolateral plating. Results suggest, if anterolateral plating is done, this should be augmented by fixation of the fibular fracture as well

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.

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

Introduction. The management of open or unstable ankle and distal tibial fractures pose many challenges. In certain situations, hindfoot nailing (HFN) is indicated, however this depends on surgeon preference and regional variations exist. This study sought to establish the current management and outcomes of complex ankle fractures in the UK. Methods. A National collaborative study in affiliation with BOTA was conducted and data retrospectively collected between January 1. st. – June 30. th. 2019. Adult patients with open and closed complex ankle fractures (AO43/44) were included. Complex fractures included the following patient characteristics: diabetes ± neuropathy, rheumatoid arthritis, alcoholism, polytrauma and cognitive impairment. We obtained data on fixation choice and patient outcomes. Institutional approval was obtained by all centres, and statistical analysis was performed including propensity matching. Results. Fifty-six centres provided data for 1360 patients. The average age of the cohort was 53.9 years ±19 (SD) with a male/female ratio of 1:1.3. 920 patients were ASA 1/2, 440 were ASA 3/4; 316 had diabetes, and 275 were open fractures. Most fractures were AO44 (71.2%) and more commonly associated with diabetes (P<0.001), alcoholism (P<0.007), open (P<0.013), and advanced age (55.7 vs. 46.3). 1227 patients underwent primary-fixation (111 HFN), with the remainder treated with external-fixation (84 definitive). Of the 111 HFN, 35% underwent primary fusion. Wound complication and thromboembolic rates were greater in the HFN group compared to ORIF groups (P<0.003), being more evident in the HFN group with primary fusion even after propensity matching. However, 1081 patients were non-weightbearing post-op contrary to the BOAST guidance. Conclusion. This is the first National collaborative audit of complex ankle fractures. Hindfoot nails were used in 9% of patients and we observed more complications in this group when compared to other cohorts. Despite BOAST guidance, only 21% of patients undergoing operative management were instructed to fully weightbear post-operatively

Introduction. Fractures of the distal tibia can be challenging to manage. Numerous surgical techniques have been utilised in managing these however there remains debate as to the optimum method of fixation. This study aims to assess the surgical outcomes and PROMs of patients with distal tibial fractures managed with intramedullary-nails or ring fixation. Methods. This is a retrospective study of patients with closed distal tibial fractures managed between 01/01/2013–31/12/2016. Adult patients admitted with closed fracture of the distal tibia fixed with an intramedullary-nail or circular-frame were included in the study. Primary outcomes were time of union, alignment of tibia post-operatively and the results of two validated PROMs (Kujala knee score and Olerud and Molander Ankle Score). Results. 12 patients had circular-frame and 14 patients underwent intramedullary-nailing. PROMS were completed in 9 (75%) of the frame group and 7 (50%) of the nail group. There was no statistically significant difference in age (p=0.095); no statistically significant difference in time to union (medians = frame 29.7 weeks, IM nail 24 weeks, p=0.212); no statistically significant difference in the coronal angulation difference from neutral (medians = frame 1.9 degrees, IM nail 2.0 degrees, p=0.940). There was statistically significant difference in sagittal angulation difference from neutral (Medians = frame 3 degrees, IM nail 0.6 degrees, p=0.041); the proportion of males in the frames groups was statistically significantly higher (p=0.033). There was no statistically significant difference in outcome of ankle scores (medians = frame 92.5, IM nail 75, p=0.132); there was a statistically significant difference in the knee score favouring the frame group (medians = frame 99, IM nail 74.5, p=0.041). Discussion. Our results show distal tibia fractures can be treated with circular-frames or IM-nails. Patients at high-risk of soft tissue complication or to minimise the risk of knee symptoms should be considered for a circular-frame

Introduction. Intramedullary nailing is gaining popularity for treatment of distal tibial fractures due to short operative time and minimum surgical trauma to soft tissues. Distal tibial fractures are commonly associated with concurrent fibular fractures at, above or below the level of tibial fractures. So far there is no consensus for fixation of fibular fractures. Materials and Methods. Fractures of fibula at or below the level of fracture of tibia were taken into consideration. Fractures of fibula above the tibial level were excluded because they do not add to stability of fracture fixation. Retrospective study was done and distal tibia-fibula fractures were separated into 2 groups based on whether fibula was fixed or not. Measures of angulation were obtained from radiographs taken immediately after the surgery, a second time 3 months later, and at 6-month follow-up. Results. 35 fracture of distal tibia and fibula were included in study. Fibula was not fixed in 21 cases while 14 fibular fixations were carried out either using short plates(8) or intramedullary pins(6). No significant differences were observed for malalignment in fracture of fibula at the level of tibial fractures. However for fractures of fibula at a level lower than its tibial counterpart, fixation of fibula significantly reduced malalignment. Conclusion. Fixation of fibula has a definite role in reducing malunion in cases where fibula was fractured below the level of tibial fracture. Fixation of fibula may increase overall stability of fixation of tibia and reduce malunion

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

Background. In a systematic review of 1125 distal tibia fractures treated with an intramedullary nail, the reported incidence of malalignment was 14%. The purpose of our study is to assess whether the addition of blocking screws during intramedullary nailing of a distal tibia fracture improved radiological outcomes. As a secondary outcome, the time to radiographic union was compared to see if a more rigid bone-implant construct had an effect on healing. Methods. We searched computerised records at a UK level 1 major trauma centre. The joint alignment was measured on the immediate post-operative radiograph and compared to the most recent radiograph. We used a difference of 2 degrees to indicate a progressive deformity and a RUST score greater or equal to 10, to indicate radiographic fracture union. Results. Twenty-seven patients were included. Nineteen patients had no blocking screw and 8 patients had a blocking screw. Five patients had a difference in their coronal plane alignment of 2 degrees or more (3/5 had no blocking screw). The results were analysed and found to be not statistically significant (p=0.88). The addition of a blocking screw has also been shown not to have an effect on the time to union. Conclusion. We have changed our surgical practice. We use a 2.5mm blocking wire to aid in fracture reduction prior to reaming / nail insertion and then remove the wire when the nail has been adequately locked. Implications. This could save surgical procedure time, radiation exposure for the patient, implant costs and potential complications

Introduction. Our unit has extensive experience with the use of Ilizarov circular frames for acute fracture and nonunion surgery. We have observed and analysed fracture healing patterns which question the role of relative stability in fracture healing and we offer limb mechanical axis restoration as a more important determinant. Aim. To assess for the presence of external callus, when only relative stability has been achieved but with anatomical restoration of the mechanical axis (ARMA). Methods. We retrospectively reviewed diametaphyseal proximal and distal tibial fractures treated with Ilizarov frame fixation in our unit between 2009 and 2017. We also reviewed cases where the Ilizarov frame technique had been used for complex femoral and humeral non-unions. Radiographs in 4 views were reviewed to assess bone healing, the presence of external callus and correction of lower limb mechanical axis. Results. 45 tibial plateau fractures, 42 distal tibial fractures and 20 humeral and 3 femoral non-unions were reviewed. Where ARMA was achieved, bone healing was observed to occur without external callus. ARMA proved more challenging in the distal tibia and where ARMA was not achieved external callus was visible during fracture healing. Conclusion. ARMA bone healing is reliable and occurs without formation of external callus, despite relative stability. This would suggest that external callus is produced not in response to just the magnitude of strain but also the direction of strain. Restoration of the mechanical axis is an important step in achieving union and needs to be considered when fixing fractures or treating non-unions

Aim. The purpose of the study was to evaluate the results of Expert tibial nailing for distal tibial fractures. Methods. All patients who had a distal third or distal end fracture of the tibia treated with the Expert tibial nail over a three year period at our institution were included in the study. A total of 44 distal tibial fractures in the same number of patients were treated with the nailing system. One patient died in the immediate post operative period from complications not directly related to the procedure and 3 were lost to follow up leaving a cohort of 40 patients for evaluation. 31 of the fractures were closed while the remaining 9 were open. The average age group of the cohort was 46.8 years with 26 males and 14 females. Results. All 40 patients were followed up to full radiological union of their tibia fractures. The average time to radiological union was 12.5 weeks for the closed fracture group and 15.1 weeks for the open fractures. The difference in time to union between the two groups was not statistically significant. There was infection around a distal locking screw in a closed fracture which settled with screw removal. Three patients in the closed fracture group required dynamisation to hasten union while none required dynamisation in the open fracture group. No bone grafting was performed on any of the patients. One patient had non union of a distal fibula fracture which required plating of as an additional procedure. On follow-up none of the patients reported knee pain or had limitation of ankle movements. Conclusion. The Expert tibial nail is an effective implant for the treatment of both open and closed distal tibial fractures with a low complication rate

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

Distal tibial fractures may be satisfactorily held in reduction by fine-wire external fixation techniques, avoiding the need for open reduction and internal fixation. However, as the use of external fixation is associated with pin-site infection, extra-articular placement of the wires is recommended. This study assesses the proximal extension of the capsule of the ankle joint in order to provide information on the safety of wire placement for distal tibia fractures. We recruited 7 patients who were electively scheduled for an MRI ankle investigation with the suspicion of osteochondral defect and/or meniscoid lesion. Patients with a history of ankle fracture or ankle surgery were excluded from the study. Just prior to MRI, the ankle joint was injected with 5 to 15 ml of contrast solution (1 mM dimeglumine gadopentetate). Selected fat-saturated T1-weighted MRI scans with sagittal, coronal and axial views were obtained. The site and proximal extent of the capsular reflection with reference to the anterior joint line were measured. All contrast-enhanced MRIs of the ankle joint space were well defined and unambiguous. Proximal capsular extensions above the plane of the anterior joint line were noted at the antero-medial and antero-lateral aspect of the joint (mean 8.9 mm, range 4.9 to 13.4 mm) and at the tibia-fibular recess (mean 18.7 mm, range 13.3 to 23.6 mm), areas that are frequently traversed by wire insertion. Conclusion: This in vivo contrast-enhanced MRI ankle study demonstrates an appreciable capsular extension above the joint line of the ankle. The proximal capsular extensions at the antero-medial and antero-lateral aspect of the joint and at the tibio-fibular recess run the risk of being traversed during fine-wire placement for distal tibia fractures. Surgeons using these techniques should be aware of this anatomy

Aims: Outcome of the distal tibial fractures treated with interlocking nail. Method: We reviewed 108 patients with distal tibial fractures which were treated in our clinic between 1990 using interlocking intramedullary nailing. 94 patients (63 men and 31 women) were found in the recent follow up. AO fracture classiþcation system was used Seventy-eight patients had concomitant fractures of the lateral malleolar and 4 had medial malleolar fractures. Eight (8,5%) of the fractures were open grade I. All fractures were managed with closed reamed nailing. In fourteen cases the nail had to be shortened. The lateral malleolar fractures were þxed before tibial nailing to ensure overall alignment. Results: Union was achieved in 89 (94,6%) fractures with a mean time of union of 4,2 months (range:3–10 months). One deep infection (1,06%) lead to nonunion. Three aseptic cases had delay union which required nail dynamization. In one more nonunion case bone grafting and þbulectomy required. Postoperative transient peroneal palsy occurred in 2 (2,12%) patients which were fully recovered. One patient developed deep posterior compartment syndrome leading to FHL conctracture, needed tendon lengthening. Conclusions: Interlocking intramedullary nailing is a reliable, safe and effective method of managing distal tibial fractures with or without minimal ankle joint involvement

Methods:. Total radiation exposure accumulated during circular frame treatment of distal tibial fractures was quantified in 47 patients treated by a single surgeon from March 2011 until Nov 2014. The radiation exposures for all relevant radiology procedures for the distal tibial injury were included to estimate the radiation risk to the patient. Results:. The median time of treatment in the frame was 169 days (range 105 – 368 days). Patients underwent a median of 13 sets of plain radiographs; at least one intra operative exposure and 16 patients underwent CT scanning. The median total effective dose per patient from time of injury to discharge was 0.025 mSv (interquartile range 0.013 – 0.162 and minimum to maximum 0.01–0.53). CT scanning is the only variable shown to be an independent predictor of cumulative radiation dose on multivariate analysis, with a 13 fold increase in overall exposure. Conclusion:. Radiation exposure during treatment of distal tibial fractures with a circular frame in this group was well within reasonably safe limits. CT was the only significant predictor of overall exposure serves as a reminder to individually assess the risk and utility of radiological investigations on an individual basis. This is consistent with the UK legal requirements (Ionising Radiation (Medical Exposure) Regulations 2000. 1. )
