The presence of an intact distal fibula is reported as a prerequisite when considering total ankle replacement and its lack is usually considered a contraindication. The purpose of the study was to describe the results of a surgical technique to reconstruct the distal fibula (Milanese fibular reconstruction technique) in the setting of a total ankle replacement and insufficient fibula.Retrospective analysis of 15 patients (15 ankles) who underwent rotational fibular reconstruction technique with minimum follow-up of 24 months. Patients were evaluated preoperatively and at the last follow-up with AOFAS Ankle and Hindfoot score, VAS pain scale, SF-12 and range of motion. Standard weightbearing radiographs were used for radiographic assessment.The average of all clinical scores significantly improved (P.001). The average radiographic parameters showed a neutral alignment. No cases of reabsorption of the new lateral malleolus were observed even in cases with complications that accounted for 2 superficial wound infection and 2 deep infections.The Milanese fibular reconstruction technique can successfully reestablish a lateral strut and in the setting of an ankle prosthesis in patients with an insufficient fibula.

Introduction The outcomes of “Weber A” type fibula fractures treated non-operatively are not well studied. The aims of this study were to investigate patient reported outcomes (PROMs) from such injuries and investigate if different radiological features of the fracture affects such outcomes. Methods Patients with conservatively managed Weber A fractures were contacted retrospectively (minimum 11 months) to measure PROMs. PROMs included the use of the Chertsey Outcome Score for Trauma (COST) as well as the time to return to work, physical activity and time to become symptom free. The effect of fracture features such as fracture height and intra-articular extension were analysed for their effect on PROMs. Results Data was collected from 72 patients from a total of 211 patients presenting with Weber A fractures. The mean COST scores were 83 (range 30−100). Patients reported on average 3.1 weeks (desk based) and 5.7 weeks (labour intensive) to return to work, 10.8 weeks to return to physical activity and 14.8 weeks to become symptom free with 21% of patients still symptomatic at follow-up. Fracture height and fractures with comminution, displacement, intra-articular extension did not appear to be associated with poorer PROMs. Conclusion The outcomes are generally excellent; however, most patients do not return to their baseline before the injury, with a significant proportion of patients remaining symptomatic at follow-up. The reported times to return to work, physical activity and symptom-free are useful to manage patient expectations. Our results dispel any assumption that Weber A type distal fibula fractures are always associated with excellent outcomes.

Background The fracture obliquity of supination-external rotation injury of the fibula is often amenable to lag screw insertion. The purpose of the study was to determine whether biomechanical differences exist between lag screws inserted from an anterior to posterior direction and from a posterior to anterior direction and the thickness of the anterior and posterior fibular cortices were correlated with biomechanical testing. Methods Ten cadaver fibulae were harvested and submitted to material testing following 3.5-mm cortical screw insertion from either an anterior to posterior direction or a posterior to anterior direction. Screw torsional insertion strength and axial pullout strength were measured. Computed tomography images of 40 consecutive patients undergoing preoperative planning for fractures excluding the fibula were examined to define fibular cortical thickness and correlate anatomic findings with the biomechanical testing. Results The axial pullout strength of lag screws inserted from posterior to anterior was significantly greater than that of lag screws inserted from anterior to posterior (p < 0.05). Screw insertion torque measurements demonstrated a similar trend although the data did not reach statistical significance (p = 0.056). The anterior cortex of the distal fibula exhibited a radiographically greater thickness than that of the posterior cortex at the same level (p < 0.001). Conclusions For oblique fractures of the distal fibula, posterior to anterior lag screw insertion exhibited improved biomechanical properties when compared with a similar screw inserted from anterior to posterior. These results correlated with the thicker cortical bone present along the anterior fibula.

Supination-external rotation type of fracture is the most common pattern of ankle fractures. Anatomical reduction of ankle is always desired and poor reduction usually leads to shortening of fibula, or alter the biomechanics of ankle leading to chronic pain as a result of failure of fixation always. Both lateral and antiglide plating of fibula achieve in accurate anatomical reduction of these fractures. But, maintaining the reduction until bony union is also required to avoid failure of hardware or non union. Antiglide construct enhances biomechanics strength of the fixation device due to its anti gliding effect of the applied plate upon weight bearing and thereby is more favourable. This study evaluated clinical outcomes and complications seen in fixations done by antiglide technique done during 2018-2021 among patients admitted with SER pattern injuries at our institute. A total of 24 patients were included in the study. Mean operative time in the study group was 57.5 ± 27.4 (range 20–120) minutes. The most commonly used plates were five-hole plates in 10 (42%) patients, six holed plates in 10 (42%) patients and seven holed in 4 (16%) patients. The median number of screws distal to the fracture line in the antiglide plate was 0.5 (range 0–2); 10 (50%) fibulas with no fixation, 8 (40%) with one and 2 (10%) with two screws. The AOFAS in the antiglide group performed at one year after surgery was 94.5 ± 6.0 (range 85–100).We conclude that the use of the antiglide plate in a posterolateral position, without using unreasonable distal screws, is an appropriate method of fixation in every short oblique lateral malleolus fractures occurring as a part of SER pattern injury of ankle.

Isolated distal fibula fractures represent the majority of ankle fractures. These fractures are often the result of a low-energy trauma with external rotation and supination mechanism. Diagnosis is based on clinical signs and radiographic exam. Stress X-rays have a role in detecting associated mortise instability. Management depends on fracture type, displacement and associated ankle instability. For simple, minimally displaced fractures without ankle instability, conservative treatment leads to excellent results. Conservative treatment must also be considered in overaged unhealthy patients, even in unstable fractures. Surgical treatment is indicated when fracture or ankle instability are present, with several techniques described. Outcome is excellent in most cases. Complications regarding wound healing are frequent, especially with plate fixation, whereas other complications are uncommon.

Background Our aim in this study was to identify the fibular footprint of the Anterior Inferior Tibiofibular Ligament (AITFL) and its relation to Wagstaffe fracture fragment size. Methods We examined 25 cadaveric lower limbs which were carefully dissected to identify the lateral ankle ligaments. The AITFL anatomy was compared to 40 Wagstaffe fractures identified from our ankle fracture database. Results The AITFL origin was from the anterior fibular tubercle with an average length of 21.61 mm (95% CI 20.22, 22.99). The average distance of the distal aspect of the AITFL footprint to the distal fibula margin was 11.60 mm (95% CI 10.49, 12.71). In the ankle fractures analyzed, the average length of the Wagstaffe fragment was 17.88 mm (95% CI 16.21, 19.54). The average distance from the distal tip of the fibula to the Wagstaffe fracture fragment was 21.40 mm (95% CI 19.78, 23.01). In total there were 22 syndesmosis injuries. There was no statistical difference in Wagstaffe fragment size between stable and unstable groups. Conclusion The AITFL fibular origin was both larger and more distal than the Wagstaffe fracture fragments seen in our institution. Therefore, this suggests that a ligamentous failure will also have to occur to result in syndesmotic instability. The size of fracture fragment also did not confer to syndesmotic instability on testing. Level of Evidence - 3

Background Ankle fractures pose a unique challenge to the treating orthopedic surgeon. Intramedullary (IM) distal fibula fixation is a relatively newer entity offering a viable option to minimize wound complications while providing similar outcomes. Our study utilizes an IM nail featuring proximal fixation via IM talons ensuring maintenance of fracture reduction this is the largest case series utilizing this novel device assessing time to weight-bearing (WB) and fracture union in addition to the safety and reproducibility of percutaneous reduction. Methods A retrospective case series was conducted on 51 ankle fractures treated with a single IM device for lateral malleolar fixation. Postoperative radiographs were assessed, qualifying reductions as good, fair, or poor based on a reduction classification. Patient charts were reviewed for fracture characteristics, reduction method, fracture union, time to WB, and complications. Results Mean follow-up time was 32.2 weeks; 47 fracture reductions (92%) were classified as good, and 4 (8%) were fair. All but 1 fracture (98%) went onto union. Average time to union was 10.3 weeks. Average time to WB with and without a walking boot was 6.8 and 11.2 weeks, respectively. Two patients experienced painful hardware. One patient had a superficial wound infection; Conclusion When evaluating this novel IM device, fracture union and time to union were found to be acceptable, with minimal wound or other complications. Percutaneous reduction permitted good fracture reduction quality. Consistent time to WB for a variety of fractures was reliably demonstrated following operative fixation with this device, including those in the elderly population.

Stabile Frakturen des oberen Sprunggelenks (OSG) konnen mit gutem Erfolg funktionell-konservativ behandelt werden, bei instabilen Frakturen fuhrt dagegen die operative Therapie eindeutig zu besseren Ergebnissen. Wie sich die Stabilitat des OSG nach Frakturen am besten bestimmen lasst, wird nach wie vor kontrovers diskutiert. Ein zunehmendes Verstandnis der Verletzungsmechanismen sowie der Biomechanik des OSG hat dazu gefuhrt, dass heute die Unterteilung in stabile und instabile Frakturen mit hoher Spezifitat moglich ist. Im vorliegenden Beitrag werden die haufig angewendeten Methoden zur Bestimmung der Stabilitat des OSG nach isolierten Frakturen des lateralen Malleolus diskutiert. Dazu gehoren die „Stresstests“ sowie die Anwendung von Rontgenaufnahmen im Stehen („weight-bearing radiographs“). Bei Einhaltung der beschriebenen Kriterien konnen uber 90 % aller isolierten, nichtdislozierten Frakturen der distalen Fibula erfolgreich funktionell-konservativ behandelt werden.

Introduction: The WHO defines giant cell tumor as a benign locally aggressive neoplasm with metastasizing capacity and aggressive behavior. Very rarely, these tumors are seen fungating, mostly when neglected. But when they do, the treatment option commonly conferred is amputation of the limb which is disabling and traumatizing. Case Report: We report three cases of fungating limb masses (proximal tibia, distal fibula, and distal radius) diagnosed with giant cell tumor histologically, undergoing limb saving surgeries with various reconstruction techniques to endorse a good quality of life and functioning limb. Conclusion: Our study is one of the earliest to report medium-term follow-up after such limb salvage procedure. We recommend that salvage procedures should be considered in giant cell tumors even in the presence of fungation if there is no neurovascular encasement. Keywords: Giant cell tumor, fungation, limb salvage surgery, endoprosthesis, mesh reconstruction.

Background Fibular stress fractures are uncommon injuries with an incompletely understood pathogenesis and predisposing characteristics. This study investigated the demographic and radiographic risk factors for fibular stress fractures. Methods A retrospective chart review from 2010 to 2018 revealed thirteen patients with isolated fibular stress fractures. Demographics, history of fracture, fracture location, bone quality, and heel alignment were collected. Results The cohort consisted of six men and seven women with a mean age of 41.8 years. The average BMI was 28.5 kg/m2. Three patients used tobacco. 69.2% of fractures were in the distal third, 23.1% proximal third, and 7.7% middle third. No patients had evidence of osteopenia. Distal fibula stress fractures were more common in women (66.7%) and associated with hindfoot valgus. Conclusion Distal third fibula stress fractures were most common and associated with hindfoot valgus. This could be due to a greater amount of axial force through fibula in this alignment. Level of evidence Level IV, Retrospective Case Series.

Premature physeal closure (PPC) may lead to clinically significant progressive angular deformity or leg length discrepancy. Many variables seem to play a role in determining which injuries result in PPC. A 8- year-old boy sustained a non-displaced physeal fracture of distal tibia and fibula. He showed no signs of PPC at 7 months post-injury. Seven years later, his ankle became painful. He had developed PPC of distal fibula causing angular ankle deformity, which was treated successfully by corrective osteotomy. To our knowledge, this is the first reported case of a non-displaced fracture of the distal fibula leading to PPC several years after the initial injury, which in our understanding was impossible to predict.

Background Reconstruction modalities described after distal fibula resection varies from no reconstruction to size matched allograft or reconstruction with ipsilateral proximal fibula. Every procedure has their own limitation. We used Prolene mesh to reconstruct lateral restraint (Meshplasty) after distal fibulectomy. Question Is a minimal reconstruction using prolene mesh (meshplasty) adequate to restore ankle stability and function post distal fibula resection? Method This retrospective analysis was performed in patients who underwent distal fibulectomy at the tertiary cancer hospital in India, between 01/01/2006 and 31/12/2016. Distal fibulectomy was performed through standard lateral approach. A prolene mesh was anchored to distal tibia and talus using screws or Ethibond sutures. Rehabilitation protocol included below knee cast for 6 weeks followed by gradual full weight bearing mobilization and ankle range of motion. Total 9 patients with mean age of 25 years (range: 13–43) got operated for distal fibulectomy during this period. Mean resection length was 13.3 cm (range: 9–20). Results Seven patients were available for final assessment at a median follow-up duration of 78 months (range: 34–161 months). Two patients developed local recurrence. Two patients developed distant recurrence both died of disease. One patient of GCT developed local recurrence in soft tissue at 30months, which was excised. Another patient of OGS developed local recurrence after 8 months along with distant recurrence. One patient of PNET developed distant recurrence at 3 months. One patient had a valgus deformity at 55 months follow up without any restriction of activity while the others had a stable ankle without any deformity. The mean MSTS score was 28 (24–29). Conclusion “Meshplasty” after distal fibulectomy is an easy, reproducible, time and cost effective reconstruction modality with minimal complications. It adequately restores ankle function while providing results comparable to other procedures. Level of evidence IV.

Even minor residual fragment malpositioning after internal fixation of ankle fractures is associated with a worse prognosis. Frequent causes for non-anatomical reduction are fibular shortening due to comminuted fractures or poor bone quality, translational or rotational malpositioning of the distal fibula within the tibial incisura with unstable syndesmosis injuries, and inadequately addressed bony avulsions of the tibiofibular syndesmosis. After operative treatment of fracture dislocations with syndesmotic fixation, in case of complex fracture pathoanatomy, and with suspected non-anatomic reduction in postoperative radiographs, computed tomography imaging of both ankles should be performed. Correction of relevant malreductions should be performed as early as possible in order to speed up rehabilitation and to avoid late sequelae due to a load shift or instability in a weight-bearing joint.Bereits geringe residuale Fehlstellungen nach Osteosynthese von Sprunggelenkfrakturen gehen mit einer verschlechterten Prognose einher. Häufige Ursachen für nicht anatomische Repositionen sind Fibulaverkürzungen bei Trümmerfrakturen oder schlechter Knochenqualität, Fehlstellungen und Malrotationen der distalen Fibula in der Tibiainzisur bei instabilen Syndesmosenverletzungen sowie nicht adressierte knöcherne Ausrisse der vorderen oder hinteren Syndesmose. Nach operativer Versorgung von Frakturen mit notwendiger Syndesmosenstabilisierung, komplexer Frakturmorphologie sowie bei jedem Verdacht auf eine ungenügende Reposition im postoperativen Röntgenbild sollte eine CT-Kontrolle unter Einbeziehung der unverletzten Seite erfolgen. Die Korrektur relevanter Fehlstellungen sollte so früh wie möglich erfolgen, um die Rehabilitation zu beschleunigen und Dauerschäden durch die Druckumverteilung bzw. Instabilität in einem lasttragenden Gelenk zu vermeiden.

Purpose The purpose of this study was to clarify the insertion sites of the anterior inferior tibiofibular ligament (AITFL) and posterior inferior tibiofibular ligament (PITFL) and related osseous landmarks on three-dimensional computed tomography images. Methods Twenty-nine non-paired, formalin-fixed human cadaveric ankles were evaluated. The tibial and fibular insertion sites of the AITFL and PITFL were identified. The morphology and location of the insertion sites and their positional relationships with osseous structures were analyzed on three-dimensional computed tomography images. Results The AITFL had a trapezoidal shape, with fibers that ran obliquely lateral from a wider insertion at the lateral distal tibia to the medial distal fibula. The PITFL had a similar shape to the AITFL; however, it ran more horizontally, with fibers running in the same direction. In the tibia, the anterior capsular ridge and the Chaput’s and Volkmann’s tubercles were useful osseous landmarks for the insertion sites. In the fibula, the centers of the insertion sites of the AITFL and PITFL were located on the edges of the distal anterior and posterior fibula, which were useful osseous landmarks. The mean distances between the center points of the tibial and fibular insertion sites of the AITFL and PITFL were 10.1 ± 2.4 mm and 11.7 ± 2.6 mm, respectively. Conclusions The relationships between the characteristic features of the distal tibia and fibula and the insertions of the AITFL and PITFL were consistent. The present findings improve the understanding of the anatomy of the insertions of the distal tibiofibular syndesmotic joint.

Ankle fractures and associated ligamentous injuries are the most common injuries of a load-bearing joint. There is still no general consensus with respect to the pathomechanism, the treatment indications and surgical techniques. The medium and long-term results are affected by a particularly high risk of posttraumatic arthritis in bimalleolar and trimalleolar fractures and fracture dislocations. There is consensus on the necessity of a thorough preoperative analysis and postoperative control of reduction for which 3D imaging is increasingly generously employed. This detects relevant pathologies, such as bony syndesmotic avulsion and partial impaction of the tibial plafond that may go unnoticed on plain radiographs. Anatomic reconstruction of the ankle mortise, the detection and treatment of syndesmotic instability, reconstruction of the tibial notch and exact placement of the distal fibula into the latter are important prognostic factors.

Distal Fibula Giant cell tumour (GCT) is a rare condition. The described methods of treatment for distal fibula GCT include excision of tumour and ankle arthrodesis, replacement of distal fibula with ipsilateral proximal fibula and autograft or allograft reconstruction. This case report describes treatment of distal fibula grade 3 GCT with involvement of syndesmosis with tumour excision, proximal fibular slide and reconstruction of ankle joint. With this technique the ankle joint movements are preserved and stability is maintained.

Proximal tibial fractures are very rare. Our case is about a six-year-old girl presented with proximal tibial triplane fracture associated with proximal and distal fibula and distal tibial fractures, as a result of a fall of a cement wall on her right knee. A radiograph and computerized tomography (CT) scan were reported as Salter-Harris type III fracture. She was treated by an open reduction and internal fixation by a screw and Kirschner wires. She was followed up for 12 months and showed an excellent knee outcome and her knee range of motion was 10-130o. Anatomical reduction and stable fixation are necessary to prevent future pain, deformity and arthritis. The case demonstrates the efficacy of using an open reduction and internal fixation by a screw and Kirschner wires in treating children with triplane proximal tibial fracture. This type of fracture is not frequently seen and a right diagnosis leads to better management, which could prevent future complications

Background: The optimal surgical management of syndesmosis injuries consists of internal fixation between the distal fibula and tibia. Much of the available data on this joint details the anatomy of the syndesmotic ligaments. Little is published evaluating the distribution of articular cartilage of the syndesmosis, which is of importance to minimize the risk of iatrogenic damage during surgical treatment. The purpose of this study is to describe the articular cartilage of the syndesmosis. Methods: Twenty cadaveric ankles were dissected to identify the cartilage of the syndesmosis. Digital images of the articular cartilage were taken and measured using calibrated digital imaging software. Results: On the tibial side, distinct articular cartilage extending above the plafond was identified in 19/20 (95%) specimens. The tibial cartilage extended a mean of 6 ± 3 (range, 2-13) mm above the plafond. On the fibular side, 6/20 (30%) specimens demonstrated cartilage proximal to the talar facet, which extended a mean of 24 ± 4 (range, 20-31) mm above the tip of the fibula. The superior extent of the syndesmotic recess was a mean of 10 ± 3 (range, 5-17) mm in height. In all specimens, the syndesmosis cartilage did not extend more than 13 mm proximal to the tibial plafond and the syndesmotic recess did not extend more than 17 mm proximal to the tibial plafond. Conclusion: Syndesmosis fixation placed more than 13 mm proximal to the tibial plafond would have safely avoided the articular cartilage in all specimens and the synovial-lined syndesmotic recess in most. Clinical Relevance: This study details the articular anatomy of the distal tibiofibular joint and provides measurements that can guide implant placement during syndesmotic fixation to minimize the risk of iatrogenic cartilage damage.

Introduction Valid epidemiological data about distal fibular fractures and their treatment strategies are missing. Innovative osteosynthesis techniques were introduced and improved during the past 15 years. The aim of this study was to investigate the epidemiologic development and the implementation of new treatment strategies in a nationwide register in Germany over a period of 15 years. Materials and methods Data of the German Federal Statistical Office from 2005 until 2019 were screened. Adults with a fracture of the distal fibula were included. Data were separated for gender, age and treatment strategy. Results During the past 15 years, there was a steady annual incidence of distal fibula fractures of 74 ± 32 per 100,000 people without any significant changes (p = 0.436). 60.1% ± 0.6% of all fractures occurred in females. The annual incidence for male was nearly constant over the different age groups, whereas for female, there was a clear increase in incidence above the age of 40. Whereas 66% of fractures in between 20 and 30 years of age occurred in male, approximately 70% of fractures above the age of 60 occurred in females. The relative quantity of locking plates increased from 2% in 2005 to 34% in 2019. In 2019, only 1.02% of the patients were operated with an intramedullary nail. Conclusions Operatively treated distal fibular fractures revealed an age dependent increase in incidence in postmenopausal women compared to younger females. Regarding the treatment strategy, there was an increase in application of locking plates. The data implicate a typical fragility fracture related age and gender distribution for distal fibula fractures.

(1) Background: Restoration of ankle biomechanics after distal fibula (DF) resection in bone sarcomas can be performed with different techniques. We report the functional and oncological outcomes of a case series, (2) Methods: Ten patients (5 females and 5 males) with a mean age of 27 years (range 10–71) were retrospectively evaluated. Following the resection, different techniques were used to reconstruct the ankle: tibiotalar arthrodesis, residual lateral malleolus fixed to the tibia, non-vascularized or rotational vascularized fibula transposition and intercalary allograft. All complications were recorded, and the functional outcomes were evaluated, (3) Results: The mean follow-up time was 54 months (range, 13–116). Six patients were free of disease while four patients died of disease. All patients had a stable ankle and bone union, which was achieved after a mean of 9.4 months (range 3–20). The mean MSTS Score was 26.7 (range 21–30). Chronic ankle pain and peroneal external nerve palsy were observed. Patients underwent additional surgeries for deep infection and for equinus ankle deformity. No local recurrence was observed. Metastasis occurred in four patients after a mean of 14.7 months (range 2–34), (4) Conclusions: After DF resection, the restoration of ankle biomechanics gives acceptable functional results, but a larger series of patients with long-time follow-up are required to confirm the durability of the reconstruction.

Syndesmotic injury can occur after trauma to the ankle, both with and without a fracture. In fractures of the ankle, syndesmotic injury occurs in about 50% of type Weber B and in all type Weber C fractures. Syndesmotic diastasis left unnoticed can lead to persisting pain, instability and progressive arthritis. This study focusses on the application of syndesmotic suture button anchor as a fixation method for the syndesmotic joint diastasis. The syndesmotic button fixation does not convert the joint into a rigid articulation and still allows micro motion to happen. In this study, Distal fibular fractures with syndesmotic injuries are selected and anatomically precontoured locking compression plate is applied for fracture fixation and syndesmotic suture button fixation is done for the syndesmotic injury and their functional outcomes studied by various modalities.

Introduction In isolated Weber B fractures (type B fibular fractures), ruling out instability is critical for safe conservative treatment. In fractures without evident medial injury, additional diagnostics like MRI scan or gravity stress test should be done to differentiate between a stable and unstable fracture. The aim of the current study is to gain more insight in current practice and treatment of type B fractures by Dutch trauma- and orthopaedic surgeons. Materials & methods In December 2017 and January 2018, 559 trauma surgeons were invited by email to join an online survey. This survey consisted of questions regarding diagnostics and treatment of isolated distal fibula fractures. Also, respondents were asked to state their preferred treatment of eight separate cases. Results In total, 161 surgeons participated, covering 68 different hospitals in the Netherlands. Of them, 32.0% treat more than 30 ankle fractures a year. Based on regular mortise radiographs, 13.6% of the respondents chose surgical treatment in case of a medial clear space (MCS) > 4 mm, 33.8% in case of a MCS > 6 mm and 45.5% in case of a MCS > 4 mm in addition to the MCS ≥ superior clear space + 1 mm. Moreover, 18.2% make use of additional diagnostics (43.9% repeat mortise view after a week, 16.6% weight bearing radiograph, 8.6% gravity stress view, 7.9% exorotation radiograph, 6.5% MRI scan, 0.7% ultrasound, 16.8% other) and 8% establishes their decision not based on the mortise radiograph. Fibular dislocation of ≥ 2 mm was used as an indication for surgical treatment by 69%. Of them, 56% decides to treat surgically in these cases, even with proven medial stability. Conclusion Many surgeons treat type B fibular fractures with a MCS > 4 mm at mortise view surgically, even without proven medial injury. Rarely, additional diagnostics as MRI or gravity stress test are performed in cases with a MCS 4–6 mm. Consequently many stable ankle fractures are treated operatively unnecessarily.

We report the case of a 13-year-old girl with multiple recurrences of an aneurysmal bone cyst of the distal fibula successfully treated with denosumab and curettage. Aneurysmal bone cysts are locally aggressive lesions with high rates of recurrence. The novel use of denosumab with curettage in a long bone showed a favorable outcome with no adverse events or signs of recurrence three years after treatment.

The distal fibula represents one of the most common fracture sites, and its epidemiology is characterized by a high incidence in both adolescence and the elderly. While fracture occurrence is influenced by trauma mechanism, a possible underlying skeletal microarchitectural deterioration in certain patient groups remains elusive. The purpose of this study was to determine the influence of age, sex, and overall skeletal status on fibular microarchitecture. We analyzed the microarchitecture of the distal fibula in 300 people by high-resolution peripheral quantitative computed tomography (HR-pQCT). Three areal bone mineral density (aBMD) groups (normal, osteopenia, osteoporosis; n = 100 per group) based on the concurrent assessment of aBMD by dual-energy X-ray absorptiometry (DXA) at the lumbar spine and total hip were established. Next to group comparisons, linear and non-linear regression analyses were carried out to assess the association between age, sex, BMI, tibial and fibular microarchitecture. While women had lower values for both trabecular bone volume fraction (BV/TVd, p

CASE A 47-year-old woman with adamantinoma of the entire left tibia and distal fibula underwent resection and reconstruction using a total tibia allograft-prosthetic composite with rotating hinged knee replacement and ankle fusion. She is ambulating without tumor recurrence with 2-year follow-up. CONCLUSION This case report offers a unique reconstruction option for extensive tibia bone primary malignancy. To our knowledge, this is the longest survival for total tibia allograft prosthetic composite reconstruction.

INTRODUCTION Tibio-talo-calcaneal (TTC) fusion is a successful surgery for Charcot neuropathy affecting the hindfoot. A case series of Charcot neuropathy is presented with almost complete loss affecting hindfoot treated with tibio-talo-calcaneal nail. MATERIAL AND METHODS Seven patients with Charcot neuropathy of the hindfoot having varying degrees of talus loss underwent tibio-talo-calcaneal nailing between January 2014 and Feb 2016 at a tertiary care hospital by a single surgeon. All the patients were type 3a as per Brodsky classification. Patients with active infection, fractures and avascular necrosis of talus was excluded from the study. The final outcome was measured using the AOFAS and FADI scores at the end of 2 years. RESULTS The mean duration of diabetes was 8.16 ± 3.12 years. Two patients (28.6%) had total and 5 (71.4%) patients had subtotal talus loss. Anterior approach was used in four, and lateral approach was used in three cases respectively. The talus was reconstructed by using the iliac crest or the graft from the distal fibula wherever appropriate. The average surgical duration was 93.28 ± 4.84 min. One patient had deep infection, 2 years after the surgery which was treated by implant removal and antibiotics. No patients had non-union. The pre-operative AOFAS scores improved from 32.2 ± 2.58 to 73.4 ± 3.36 at 2-year follow-up (p < 0.0001). Similarly, the pre-operative FADI scores were 31.74 ± 1.98 which improved to 65.94 ± 3.68 at the end of 2 years (p < 0.0001). CONCLUSION Retrograde tibio-talo-calcaneal nail is a good option for limb salvage in patients with severe talus loss with good functional outcome. LEVEL OF EVIDENCE Therapeutic IV.

Category: Ankle; Trauma Introduction/Purpose: The aim of our study is to compare two types of plates, one third tubular plate and LCP distal fibula plate, evaluating the clinical outcome and the skin complications associated with their use. Methods: We collected the data of 122 consecutive unimalleolar or bimalleolar fractures treated by internal fixation for a closed, displaced distal closed fibular fracture. Exclusion criteria were: 1) open ankle fractures,2) trimalleolar fractures, 3) previous ankle fractures 4) severe venous insufficiency, 5) ankleosteoarthritis previous to surgery, 6) associated ankle dislocation. After this selection, 93 patients were included in our study and assigned in two groups, based on using of different implant: in group A48 patients were treated with one-third tubular and in group B 45 patients were treated with LCP distalfibula plate. There were no significant differences in the baseline characteristics. Patients received the same surgical procedure and the same post-operative care, then they were radiologically evaluated at1-3-12 months and clinical examination was made at 24 (range 15-36) months using AOFAS clinical rating system. All data were evaluated using chi-square test. Results: At the final 24-month follow-up a comparison between the two groups showed no statistical significant differences in reduction accuracy and bone union ratio at radiological examination. The wound complications rate of the overall study group was 7.6%. There were no statistical differences in the rate of wound complications between the two groups. There were no differences between both group in percentage of hardware removal at follow-up (overall 5.4%). In the group A occurred 1 deep infection, 2 superficial infection, no wound dehiscence; in group B occured 1 deep infection, 1 superficial infection and 2 wound dehiscence. There were no statistical differences in the rate of wound complications between the two groups (p=0.70; Fisher exact test). Conclusion: Our study has shown no difference in radiographic bone union rate, no significant differences in terms of clinical outcomes, in time of bone reduction and wound complication rate between the LCP distalfibula plate and conventional one-third tubular plate. RCT or metanalasys are in this case useful to improve scientific evidence and give more information for the correct surgical treatment of ankle fractures.

Category: Trauma; Ankle Introduction/Purpose: Truly isolated Weber B distal fibula fractures are stable injuries that usually recover well following non- operative treatment, however the concern over the possibility of a medial ligament injury, and ankle instability has traditionally lead to regular surveillance in the fracture clinics to exclude delayed talar shift developing. After recent studies suggesting this risk is low we introduced a new functional treatment protocol and present our early results. Methods: 141 consecutive patients presenting acutely with isolated Weber B fractures without talar shift during a 12 months period were included. ED notes and radiographs were reviewed. All patients were splinted in a removable boot, and allowed to fully weight bear up to their comfort levels. Patients without signs of a medial ligament injury were then discharged from follow-up with advice to wear the boot for 6 weeks, an information leaflet and exercise sheet and a helpline number in case of difficulties. If they wanted clinic review this was organised. If signs of a medial ligament injury were documented, or the medial findings were not clear the patient was reviewed with up to date radiographs in the fracture clinic at 4 weeks post-injury. If talar shift developed the patient was to be converted to operative treatment. Olerud and Molander scores were collected between 6 and 12 months post- injury. Results: There were 51 patients without signs of medial ligament injury and of these 23 were discharged according to protocol and 28 patients attended fracture clinic. 89 patients had signs of medial ligament injury or no documented medial findings and of these 65 attended fracture clinic. One discharged patient re-accessed care. Of 93 patients reviewed in the fracture clinic none developed delayed talar shift. One underwent delayed ORIF for ongoing fibula discomfort and the remainder continued with non- operative treatment. 99 (70%) patients provided outcome scores. The mean Olerud and Molander score at a minimum of 6 months follow-up was 87 and the median score was 100. No significant difference was found between treatment arms. The scores were comparable to those in the published literature. Conclusion: We conclude the risk of delayed talar shift is low and satisfactory outcomes can be safely achieved with our functional protocol. Additional tests/imaging to establish the integrity of the medial ligament may be unnecessary.

Category: Ankle; Trauma Introduction/Purpose: In the setting of apparently isolated distal fibula fractures, the radiographic gravity stress view (GSV) has been validated as a reliable method to determine mortise stability. Based on previous studies demonstrating that plantarflexion can increase the measured medial clear space (MCS), patients are often asked to actively hold their ankle in a neutral position. However, it has not been studied whether dynamic muscle activation in the form of attempted dorsiflexion and/or supination can reduce and realign an unstable mortise. If these efforts can overcome gravity, resultant images could lead to a false negative result and missed diagnosis of instability. The goal of the present investigation is to determine if active effort by the patient can influence MCS measurements in proven unstable bimalleolar-equivalent ankle fractures. Methods: Eighteen consecutive patients with apparently isolated distal fibula fractures (Weber-B type) identified on initial nonweightbearing radiographs were assessed for mortise stability with a standard, unassisted GSV. If the radiograph demonstrated MCS widening > 4 mm, 3 additional views were performed: GSV with an assistant manually maintaining the ankle in a neutral position; GSV with the patient actively dorsiflexing the ankle to the same neutral position; and GSV with the patient actively dorsiflexing and supinating the foot to the same neutral position. All radiographs were digitally obtained and measured using a DICOM measurement tool. The MCS was measured by the senior author (JYK) who was blinded to the nature of the ankle position. Statistical analysis of the data was then conducted. Results: Of the eighteen patients who met inclusion criteria, the mean age was 48.9 years (range: 22-85, SD=18.9). Twelve patients (66%) were female and six (33%) were male. The laterality was evenly split with nine patients presenting with a right ankle injury and nine left ankles. The data was non-parametric; therefore, a Friedman’s test was utilized for analysis between the different MCS measurements per patient. There was no statistically significant difference in the measured MCS in any of the three tested scenarios, χ2(2)=4.261, p=0.119. Only 5 of 18 subjects had any measurable decrease in their MCS when asked to supinate their foot. Of these 5, the maximum reduction was 1.21mm. The remainder of patients had an increase in MCS ranging from 0.1 to 4.0mm. Conclusion: This investigation supports the notion that the gravity stress test is unlikely to yield false negative results when patients attempt to actively maintain a neutral ankle position during imaging. There was a non-significant inverse trend indicating that dynamic effort may in fact further displace the mortise as indicated by an increased MCS in several study participants, rather than reduce it. Thus, one can conclude that despite voluntary effort, patients with bimalleolar-equivalent ankle fractures are unlikely able to overcome the effect of gravity on the unstable mortise.

Category: Trauma; Ankle Introduction/Purpose: Intramedullary fixation of the distal fibula in unstable ankle fractures provides an alternative treatment strategy to traditional techniques and may reduce the complication profile. While often reserved for soft-tissue protection or elderly patients, the indications for this technique continue to expand. The purpose of this study was to evaluate the radiographic outcomes of ankle fractures treated with intramedullary fixation of the distal fibula with screw or flexible fixation of the syndesmosis. Methods: A retrospective case-series was performed of patients >18 years old with unstable ankle fractures treated at a single institution. Patients were treated with intramedullary fixation of the distal fibula and screw or suture-button fixation of the syndesmosis if indicated. Radiographic parameters measured included the medial clear space, tibiofibular overlap, tibiofibular clear space, talocrural angle, and fracture displacement. Fracture pattern, comorbidities, and postoperative complications were also assessed. Results: Fourteen patients (6 males, 8 females) with torsional ankle fractures (71% SER-IV patterns) were included in the study with a mean follow-up period of 5 months. Five patients had suture-button fixation and one patient had trans-syndesmotic screw fixation of the syndesmosis. All patients had improvement in radiographic parameters following surgical stabilization. Medial clear space decreased from a mean of 5.6 +- 3.1mm to 2.8 +- 0.79mm (pConclusion: This case-series demonstrates the successful use of intramedullary fixation of distal fibula fractures in unstable ankle injuries with good radiographic and clinical outcomes. The use of an intramedullary device does not preclude trans-syndesmotic screw or suture-button fixation of concomitant syndesmotic injuries. Orthopedic surgeons can consider this treatment strategy as an alternative to traditional techniques.

Distal tibiofibular syndesmosis is a complex anatomical structure that is essential for the stability and function of the ankle. Ankle fractures are a common source of chronic syndesmosis instability with associated functional impairments and early development of osteoarthritis. Case presentation: we described a case of a 28-year-old patient who presented with symptomatic ankle subluxation and chronic syndesmosis instability. Eight months earlier, the patient sustained a minimally displaced ankle fracture that had been treated conservatively elsewhere. The surgical approach included the anatomical realignment of the distal fibula with a lengthening derotational osteotomy and tibiofibular syndesmosis reconstruction using an autologous semitendinosus tendon graft. One year after surgery, the ankle function was restored, and the patient was asymptomatic. Conclusion: The instability of ankle fractures should be carefully evaluated during the treatment decision-making. Surgical treatment of syndesmosis instability should be performed even in chronic cases to restore function. The reconstruction of syndesmosis with semitendinous tendon graft associated with fibular length and realignment improves the ankle stability and function.

Background: In the setting of apparently isolated distal fibula fractures, the gravity stress view (GSV) is a validated method to determine mortise stability. There is currently no published data evaluating whether dynamic muscle activation can reduce an unstable mortise. If patients with instability can overcome gravity, resultant images could yield false-negative results. The goal of this investigation was to determine if patient effort can influence medial clear space (MCS) measurements in proven unstable bimalleolar-equivalent ankle fractures. Methods: Patients presenting with Weber B fibula fractures were assessed for mortise stability using the GSV. If the GSV demonstrated instability based on MCS widening >4 mm, 3 additional views were performed: GSV with an assistant maintaining the ankle in a neutral position; GSV with the patient actively dorsiflexing to neutral; and GSV with the patient actively dorsiflexing and supinating the foot. Twenty-four consecutive patients met inclusion criteria, with a mean age of 48.7 (range, 22-85) years. Fifteen patients (62.5%) were female and 9 (37.5%) were male. The laterality was evenly divided. Results: The mean MCS was 5.8 ± 2.0 6.0 ± 2.6, and 6.2 ± 2.7 mm for the manual assist, active dorsiflexion, and active supination radiograph measurement groups, respectively ( P = .434). Only 5 of 24 subjects had any measurable decrease in their MCS with active supination, with a maximum change of 1.2 mm. The remainder of the patients had an increase in MCS ranging from 0.1 to 4.0 mm. Conclusion: There was no significant difference between measurement states indicating that muscle activation is unlikely to yield a false-negative result on GSV. Mortise instability, secondary to deep deltoid injury in the presence of gravity stress, is unlikely to be actively overcome by dynamic stabilizers, supporting the validity and specificity of the GSV. Level of Evidence: Level III, prospective study.

Background. There has been historical debate as to whether the distal tibiofibular syndesmosis can be overtightened during operative fixation. We used finite-element analysis to determine if overtightening of syndesmotic screws can cause widening of the lateral gutter clear space in the ankle joint. Methods. A 3D finite-element model was constructed and analyzed using geometries from a computed tomography scan of a cadaveric lower leg. Starting 2 cm from the plafond, screw fixation was simulated at 5-mm increments to a distance of 5 cm from the plafond. The fibula was compressed 2 mm toward the tibia at each interval, and the change in distance between the lateral talus and distal fibula was measured. Results. Medial deflection of the fibula resulted in widening of the lateral clear space, which was proportional to the amount of deflection. The effect increased as screws were placed closer to the plafond, with 1.5 mm of widening at 2 cm (0.76 mm/mm) versus 0.7 mm at 5 cm (0.34 mm/mm). Conclusion. Our finite-element model demonstrated that overtightening of the distal tibiofibular syndesmosis with medial fibular displacement can cause widening of the lateral clear space. Clinical relevance. The results suggest that screws placed farther from the plafond widen the lateral clear space to a lesser degree, which may be advantageous during surgical fixation to prevent clear space widening and increased tibiotalar contact forces.

Osteoporotic fractures of the distal fibula in elderly patients is a challenge to manage. Non-operative management has a poor outcome so operative management is preferred. There are a variety of options for operative management such as locked plate systems, anti-glide plate construct, dual plating constructs, fibula nail, plate with tibial pro-fibular screws, and injectable bone cement (polymethylmethacrylate (PMMA), calcium phosphate). However, no clear guidelines exist for the operative management of osteoporotic distal fibula fractures. The surgeon should detect osteoporotic fractures early to make the best use of resources and avoid complications such as implant failure.

Stress fractures of the ankle and hindfoot are common injuries in athletes. Most of these fractures can be treated nonoperatively, but certain factors including fracture location, vascular supply, lower leg alignment, and return to play considerations may require surgical intervention. Stress fractures of the ankle and hindfoot can also be classified as low risk and high risk in regard to propensity to heal with conservative treatment. Generally, low-risk fractures include the distal tibia, distal fibula, talus, and calcaneus. High-risk fractures include the medial malleolus and navicular. The treating health-care provider should have a low index for suspicion for stress fracture and be able to identify risk factors in regard to bone health, structural alignment, and training/competing issues in order to achieve a quick recovery and minimize the chance for recurrence of injury.

The patient was a 26-year-old man who fell while riding a motorcycle and friction led to defects in the lateral malleolus and soft tissue of the ankle. Although the wound surface healed with scarring and skin grafting, the patient had symptoms of ankle joint instability 4 months after the injury. Using a second metatarsal composite tissue flap with a dorsalis pedis artery pedicle, we repaired the soft tissue defect of the ankle and reconstructed the lateral malleolus. The head of the metatarsal bone was used to reconstruct the lateral malleolus and the flap was used to cover the wound surface. The distal fibula and metatarsus were completely healed 36 months postoperatively. The ankle had maintained stability at this time, with equal limb length and only a mild limitation of dorsal flexion in the ankle joint. The patient could walk, jog, and walk up and down stairs without limitations. There was no pain or limitation in activity at the donor site. Our findings suggest that the second metatarsal composite tissue flap with a dorsalis pedis artery pedicle is an effective option in reconstruction of the adult distal fibula.

Adult-acquired flatfoot deformity is a progressive flattening of the arch of the foot that results from posterior tibial tendon insufficiency with a predilection for middle-aged women. A lateralized force vector associated with hindfoot valgus in adult-acquired flatfoot produces lateral ankle pain due to impingement at the lateral hindfoot, which can even lead to stress fractures of the distal fibula. Here, we present the rare case of a 73-year-old woman who presented with stress fractures of the bilateral taluses and unilateral distal fibula accompanied by severe adult-acquired flatfoot deformities.

Background Open reduction and internal fixation is the current standard of treatment of displaced distal fibula fractures, whereupon using a lag screw often is impossible because of a multifragmantary fracturezone. This study investigates in what extend polyaxial-locking plating is superior to non-locking constructs in unstable distal fibula fractures. Methods Seven pairs of human cadaver fibulae were double osteotomized in standardized fashion with a 5mm gap. This gap simulated an area of comminution, where both main fragments were no longer in direct contact. One fibula of the pair was managed using a 3.5-mm screw in a polyaxial-locking construct and the other fibula in a non-locking construct.

Medial column (deltoid ligament) integrity is of key importance when considering the stability of isolated lateral malleolus ankle fractures. Weight-bearing radiographs are the best method of evaluating stability of isolated distal fibula fractures. Computed tomography (CT) scanning is mandatory for the assessment of complex ankle fractures, especially those involving the posterior malleolus. Most isolated trans-syndesmotic fibular fractures (Weber-B, SER, AO 44-B) are stable and can safely be treated non-operatively. Posterior malleolus fractures, regardless of size, should be considered for surgical fixation to restore stability, reduce the need for syndesmosis fixation, and improve contact pressure distribution.

Aims & Objectives : Interosseous border of tibia splits distally into anterior and posterior edges. These edges project into anterior and posterior tubercles enclosing a notch called fibular incisura that articulates with the distal fibula forming distal tibio fibular syndesmosis. The aim of the present study was to obtain the morphometric data of fibular incisura that may be helpful for the orthopedic surgeons in ankle reconstructive surgeries and ankle joint replacement. Materials & Method: To describe the morphometry of the fibular incisura, a total of 100 tibia [right 55 and left 45] were obtained from the Department of Anatomy, NRI Medical College, Chinakakani. The width of tibia, width, depth, height of fibular incisura and the length of anterior, posterior incisural tubercles were measured in both right and left tibia using digital vernier calipers. Right and left side para meters were compared using Karl Pearson Coefficient [r value]. Results: Average values for the width, depth and height of the fibular incisura were 16.83mm on the right side and 17.42mm on the left side, 2.85±1.38mm on the right and 2.9±1.57mm on the left side, 38.82±5.8mm on the right side and 38.72±7.68 mm on the left side respectively. While average lengths of anterior and posterior tubercles of the fibular incisura were 13.19±1.96mm, 15.71±2.03mm on the right side and 12.6±1.49mm, 15.66±1.41mm on left side. Thirty-three tibia presented deeply concave [depth>4cm], and sixty-seven had shallow fibular incisura [depth

Background: Giant cell tumor (GCT) is a destructive bone tumor. The predilection of the GCT is mostly on the epiphysial of long bones. GCT of the distal fibula is a very rare case that becomes challenging in surgical management. The chosen surgical management is crucial and still under debate.Case Report: A 38-years-old male complaint of a painful lump in the lateral side of his left ankle for three months. Plain radiographs demonstrate a lytic lesion involving distal fibula, appropriate with 2nd-grade Campanacci. MRI showed a mass centered on the distal fibula with intermediate to high T2 signal, low T1 signal, and homogenous contrast enhancement. The patient underwent a wide excision and reconstruction of the distal fibula with a fibular head graft from the ipsilateral side. After fifteen months of evaluation, the result was excellent. The patient can full-wight-bearing with a full range of ankle joint movement, return to daily activities without pain, and no signs of recurrence. Functional status measured by the MSTS and CAIT showed good results, with total scores was 28 and 27.Discussion: Ten centimeters distal fibula is a crucial component to form stability of the ankle. Reconstruction of the distal fibula after wide excision requires the bone graft and is considered to maintain ankle stability. It can be achieved using autograft from fibula or iliac crest.Conclusion: Reconstruction of distal fibula GCT with proximal fibular autograft showed a great result. This method is a viable option as it provides good pain relief and functional improvement.

Musculoskeletal tumours of the lower limbs especially malignant tumours are not common. The fibula is the site of primary bone tumours as reported in 2.4% of lower limb tumours with the proximal third being more frequently involved than the distal segment. Osteosarcoma is the most common primary malignant bone tumour of nonhaematopoietic origin, with distal fibular involvement in 0.47% of patients. The advances in imaging techniques and neo-adjuvant chemotherapy have now made it possible to accurately define the extent of tumour and plan limb salvage with tumour resection. The purpose of this case report is to highlight the successful outcome of limb salvage procedure with a five year follow up in an 11-year old boy with distal fibular osteosarcoma. Limb salvage surgery with distal fibulectomy and retention of the foot are a good alternative to radical amputation.

The purpose of this study was to examine the effect of the Mulligan Concept (MC) Mobilization with movement (MWM) in the treatment of clinically diagnosed acute lateral ankle sprains in competitive athletes.A prospective case series of 5 adolescent patients, ages ranging from 14 to 18 years (mean = 15.8 ± 1.64), that suffered an acute lateral ankle sprain (LAS). Patients were treated with the MC lateral ankle MWM. Mobilization was directed at the distal fibula or, using a modified MWM, 2-3 inches proximal to the distal fibula. Using pairedTreatment lasted an average of 9 days (mean = 9.2, ±SD 3.96) from intake to discharge. During that time frame, patients reported decreases in pain on the numeric pain rating scale (NRS), disability on the Disablement in the Physically Active (DPA) scale and an increase in function on the patient-specific functional scale (PSFS); and an immediate decrease in pain on the NRS within the first treatment. The minimal detectable change for the PSFS and NRS were exceeded from intake to discharge. Additionally, the minimally clinical important differences were exceeded on the NRS and DPA scale.The evidence presented in this Level-4 case series supports the use of the MC lateral ankle MWM to treat patients diagnosed with acute grade II LAS. Patients in this case series reported immediate decreases in pain and immediate increases in function. Therefore, further investigation of the MC lateral ankle MWM is warranted.

Introduction: Ankle fractures are the most common type of fractures treated in orthopaedics with isolated malleolar fractures, accounting for two-thirds of fractures. The most common injury mechanism is supination external rotation, which accounts for the majority of all ankle fracture patterns. Supination external rotation stage II is the classic short oblique fracture of the distal fibula without a medial side injury, which responds well to non-operative treatment as it is a stable fracture. The purpose of this study is to compare efficacy of elasticated support bandage versus plaster cast in the patient with isolated lateral malleolus fracture (Lauge-Hansen supination- eversion external stage II.) Method: A prospective comparative study was carried out in the Department of Orthopaedics in Bir Hospital from February 2007 to January 2009. Patients with ankle fracture were initially treated by below knee posterior slab for seven days to allow the swelling to subside and on seventh day follow-up they were grouped in two groups. Group A were patients with below knee cast and Group B were elasticated support bandage. Both groups were followed-up in the 5 th week for cast or elasticated bandage removal and were evaluated after a week, thereafter, every monthly for 3 months and finally at 6 month. Result: Of the 48 cases enrolled, the mean age of the patients was 38.85 years. The common mode of injury was fall from height followed by road traffic accident. The modified subjective ankle score of Olerud and Molander (1984) was found more in group B in comparison to group A in all follow ups. In initial three successive follow ups at 6 week, 12 week and at 3 month subjective score was found statistically significant ( p> 0.05) however, it was not significant at 6 month follow up. The range of motion was significantly improved in group B in all follow ups but the difference between the two groups at 6 weeks and 10 weeks follow ups was statistically significant. Immobilized group required less analgesic but the difference was not significant statistically. Conclusion: Both below knee cast and elasticated support bandage treatment methods are safe, satisfactory and equally effective with a better early result in elasticated support bandage. Supination External Rotation stage II type fracture can be treated conservatively, if there is no medial tenderness. Journal of Society of Surgeons of Nepal Vol. 17, No. 2, 2014, Page: 7-11

Solid variant aneurysmal bone cyst is a rare benign bone lesion, representing a small fraction of all aneurysmal bone cysts. The imaging appearance and histologic features may overlap with other benign and malignant neoplasms, posing a diagnostic dilemma for clinicians, pathologists, and radiologists. We present a case of solid variant aneurysmal bone cyst of the distal fibula and review the radiologic and histologic features important for diagnosis.

Background Inadequate ankle syndesmotic reduction is a common and important cause of poor outcome after surgery. It is not clear what magnitude or planes of displacement impact most. Many computerised tomography (CT) measurement techniques rely on landmarks that are difficult to reproduce, and none measure all types of mal-positioning in a single protocol. The purpose of this study was to design and validate a protocol for measuring the distal tibio-fibular relationship. Methods We devised a method for measuring fibular diastasis, antero-posterior translation (APT) and fibular length on CT images. CTs of sixteen un-injured ankles were examined using our protocol and that of an established alternative method for comparison. The measurements were recorded by two independent observers and repeated for inter- and intra-observer agreement scores. Results Our method showed inter- and intra-observer agreement of r =0.994 and r =0.999, demonstrating strong agreement. This compared to r =0.218 and r =0.820 respectively for the comparative protocol. Conclusion This ankle CT measurement protocol is accurate, reproducible and simple to use. Its aim is to be a useful tool for clinicians to quantify post-operative mal-positioning of the distal fibula in comparison to the un-injured ankle. We believe that routine, bilateral, post-operative CT imaging will lead to improvements in the understanding and outcomes of the treatment of complex ankle fractures. To our knowledge no other validated measurement of fibular length on CT images exists in the literature.

Introduction. Distal fibula fractures are common orthopaedic injuries that often require open reduction internal fixation (ORIF) to anatomically reduce the fracture and minimize the risk of posttraumatic arthritis. In certain clinical situations, stouter fixation may be advantageous to decrease the risk of fixation failure. In this study, the authors report on 12 patients who underwent distal fibula ORIF with 2 one-third tubular plates. Materials and Methods. Twelve consecutive patients who underwent distal fibula ORIF with 2 one-third tubular plates were retrospectively reviewed. Clinical and radiographic outcomes were reviewed, and functional outcomes were obtained using the Foot and Ankle Outcome Score (FAOS). Institutional review board approval was obtained. Results. All 12 fractures healed clinically and radiographically. One patient was lost to follow-up after healing of the fracture. One patient had removal of fibular hardware at 15 months after surgery. Ten patients had no hardware related pain and good ankle function. FAOS scores were obtained at a mean of 25.6 months after surgery and were as follows: pain (87.6, SD = 9.5), activities of daily living (90.4, SD = 14.5), symptoms (93.3, SD = 9.5), sports (89.5, SD = 18.1), and quality of life (57.4, SD = 21.3). Conclusions. Double plating of distal fibula fractures is a viable technique for problem fractures that potentially provides a readily accessible, low-cost alternative to other means of enhancing fixation.
