Posteromedial approach for the surgical management of posterior talar body fractures.

Posterior talar body fractures are challenging with regards to optimal surgical approach, especially fractures involving the articular surface for which anatomical reduction is required. These fractures are often reduced surgically utilizing either the medial malleolus osteotomy (MMO), or posteromedial approach (PMA). While the MMO exposes the medial aspect of the body of the talus and avoids compromising the blood supply to the anterior talus through the deltoid ligament, it provides minimal access to the posterior process and to the posteromedial talar dome. Furthermore, by definition this approach results in iatrogenic damage to the articular cartilage and a trace loss of bone at the osteotomy site, which may preclude an anatomic reduction. The PMA on the other hand provides visualization of the entire posterior talus, including the posterior process and posterior aspect of the talar dome, thus it may indicated for appropriate reduction and visualization of fractures of these sites. This article describes the technique and reports on outcomes in the largest series of patients reported in the literature to our knowledge who sustained posterior talar body fractures that were managed through this approach.

Outcomes of Tibiotalocalcaneal Arthrodesis vs Talar Body Prosthesis as Treatment of Collapsed Avascular Necrosis of the Talus: A 10- to 13-Year-Follow-up Retrospective Comparative Study.

BACKGROUND: Joint salvage surgeries such as tibiotalocalcaneal arthrodesis and talar prosthesis are commonly used in the surgical treatment of collapsed avascular necrosis of the talus (AVNT). However, differences in outcomes of these 2 surgical treatments are still inconclusive. This study compared the 10- to 13-year outcomes and 10-year survivorship rates of tibiotalocalcaneal arthrodesis and talar body prosthesis in the surgical treatment of collapsed AVNT. METHODS: A retrospective comparative study was conducted of patients who underwent either tibiotalocalcaneal arthrodesis or talar body prosthesis implantation between 2005 and 2012. The demographic matching process resulted in 24 patients per treatment group. Clinical outcomes were evaluated using a numeric rating scale (NRS) of 2 hours of activities of daily living (ADL) and Foot and Ankle Ability Measure (FAAM) for ADL. Radiographic assessments included the incidence of nonunion, adjacent joint arthritis, and prosthesis loosening. The 10-year survivorship of both surgical treatments was calculated. A P value of less than .05 was considered statistically significant. RESULTS: The median NRS of 2 hours of ADL and FAAM score for ADL were statistically significantly better in the talar body prosthesis group, with P values of .001 and <.001, respectively. The statistically significant differences in FAAM score for ADL exceeded the minimum clinically important difference. In the tibiotalocalcaneal arthrodesis group, nonunion was observed in 7 of 24 patients (29.2%). No prosthesis loosening was reported in the talar body prosthesis group. The 10-year survivorship was statistically significantly higher in talar body prosthesis than tibiotalocalcaneal arthrodesis (95.8% vs 70.8%), P = .023. CONCLUSION: Talar body prosthesis implantation in selected eligible patients demonstrated statistically significantly better 10- to 13-year clinical outcomes and higher 10-year survivorship compared with tibiotalocalcaneal arthrodesis in the surgical treatment of collapsed AVNT. LEVEL OF EVIDENCE: Level III, retrospective cohort comparative study.

Influence of Surgical Approach and Fixation on Complications in Talus Fractures: A Multicenter Review.

Fractures of the talus are infrequent injuries often associated with substantial morbidity and imperfect outcomes. We undertook a retrospective review of talus fractures at multiple level 1 trauma centers in order to identify common treatment patterns and potential predictors of complications. All cases of talar fractures meeting inclusion criteria at our institution were reviewed. 54 of 103 talus fractures met inclusion criteria. 33 (61.1%) involved the talar neck, 13 (24.1%) the talar body, and 6 (9.2%) involved the lateral process. The most common etiology was motor vehicle accidents, accounting for 27 (50.0%). Mean follow up was 13.6 months (range 8-52 months). 37 (68.5%) fractures were fixated with screws, and 17 (31.5%) were fixated with a plate construct. Single and dual incisions were used in 63.0% and 25.9% of cases, respectively. Complications were seen in 46.3% of cases, with post-traumatic osteoarthritis being the most common complication (35.1%). Avascular necrosis occurred in 4 (7.4%) patients. No independent variables met the statistical threshold to be associated with complications. The present data alludes to possibility of over-reporting complications due to historical literature and the need for further studies.

Atypical Talus Fracture: A Case Report.

Introduction: Talus fractures are relatively rare injuries. These injuries are very serious because they can compromise the motion of foot and ankle and result in severe disability. Fractures of talar neck and body constitutes about 40% of all talus fractures. These occur secondary to high energy trauma most commonly motor vehicle collisions or fall from height. Fractures involving the lateral process results due to ankle inversion and dorsiflexion. Majority of talar surface is covered by articular cartilage and its role in force transmission between leg and foot makes successful treatment of such injuries a mandatory prerequisite to regain function. We present an atypical case of talus fracture in which fracture plane extends from posterior aspect of lateral talar process involving the body in coronal plane. Not much of literature has been published in this regard. Case Report: A 28 year old male presented with pain in the left ankle following fall from a tree. Following the radiological investigations, in coronal plane fracture line extends from posterior aspect of lateral talar process into the body medially and anteriorly. Internal fixation of the fracture was done by an open approach and a strict rehabilitation protocol was followed. At three months the patient had satisfactory healing of fracture without any irregularity of the articular surface and ambulant pain free with full range of ankle movements. Conclusion: There are several choices to treat talar fractures. The ideal treatment should be customized as per the fracture morphology. Open reduction and internal fixation is one of the best options to restore the tibiotalar and subtalar joint congruency and to prevent post traumatic arthritis. Appropriate diagnosis and perioperative treatment is the key to success in talar fracture management.

Arthroscopic reduction and internal fixation (ARIF) for talar body fractures: systematic review.

PURPOSE: This study aimed to systematically assess the available literature on the technique and results of arthroscopic reduction - internal fixation for displaced fractures of the talar body. METHODS: A systematic review was made of the available literature on MEDLINE, EMBASE, and the Cochrane Library database, including studies from January 1985 to July 2021. The literature search, data extraction, and quality assessment were conducted by two independent reviewers. Surgical technique, perioperative management, clinical outcome scores, radiographic outcomes, and complication rates were evaluated. RESULTS: Out of 37 articles reviewed, 12 studies met the inclusion criteria. The studies included reported on the results of 22 patients. No complications were observed in any of the patients treated. CONCLUSIONS: The included studies had too many weaknesses to allow the pooling of data or meta-analysis. However, percutaneous arthroscopic talar internal fixation appears to be a good option for uncomplicated displaced intra-articular talar fractures. Appropriately powered randomized controlled trials with long-term follow-ups are required to confirm the effectiveness of this technique. LEVEL OF EVIDENCE: Level IV, a systematic review of Level IV studies.

Association of Talar Neck Fractures With Body Extension and Risk of Avascular Necrosis.

BACKGROUND: The objective of this study was to determine whether talar neck fractures with proximal extension (TNPE) into the talar body are associated with higher rates of avascular necrosis (AVN) compared to isolated talar neck (TN) fractures. METHODS: A retrospective review of patients sustaining talar neck fractures at a level I trauma center from 2008 to 2016 was performed. Demographic and clinical data were collected from the electronic medical record. Fractures were characterized as TN or TNPE based on initial radiographs. TNPE was defined as a fracture that originates on the talar neck and extends proximal to a line subtended from the junction of the neck and the articular cartilage dorsal to the anterior portion of the lateral process of the talus. Fractures were classified according to the modified Hawkins classification for analysis. The primary outcome was the development of AVN. Secondary outcomes included nonunion and collapse. These were measured on postoperative radiographs. RESULTS: There were 137 fractures in 130 patients, with 80 (58%) fractures in the TN group and 57 (42%) in the TNPE group. Median follow-up was 10 months (interquartile range, 6-18 months). The TNPE group was more likely to develop AVN as compared to the TN group (49% vs 19%, P < .001). Similarly, the TNPE group had a higher rate of collapse (14% vs 4%, P = .03) and nonunion (26% vs 9%, P = .01). Even after adjusting for open fracture, Hawkins fracture type, smoking, and diabetes, AVN still remained significant for the TNPE group as compared to the TN group with an odds ratio of 3.47 (95% CI, 1.51-7.99). CONCLUSION: We found a higher rate of AVN, subsequent collapse, and nonunion in patients with TNPE compared to isolated TN fractures. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Effect of percutaneous and arthroscopically assisted osteosynthesis of talar body fractures.

BACKGROUND: Talar fractures are relatively uncommon, and the complex anatomy of the talus impedes their visualization, reduction, and fixation without performing an arthrotomy or osteotomy. To date, few studies have evaluated the complications of arthroscopically assisted percutaneous talar osteosynthesis. This clinical retrospective study aimed to investigate the effectiveness of this procedure according to the complications and functional outcomes. METHODS: Arthroscopically assisted percutaneous talar osteosynthesis was performed in 15 patients (10 men and 5 women) with 16 fractures (one bilateral). The mean patient age was 31 years (range, 14-52 years). The Sneppen classification of the fractures was type II in 14 cases and type III in 2 cases. RESULTS: Fifteen patients were followed up for 36 months on average (range, 18-65 months). No skin infection, osteomyelitis, or skin necrosis was observed in any patient. During the follow-up, no bony non-union or delayed union was found. At the final follow-up, 2 out of the 15 patients (13.3%) had peri-talar osteoarthritis. The ankle-hindfoot pain was absent in 11 patients (12 ankles) and mild in 4 patients. Based on the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, functional results were excellent in 7 ankles and good in 9 ankles. The mean AOFAS ankle-hindoot score of the patients was 85.7 (range, 79-93). CONCLUSION: Arthroscopically assisted percutaneous talar osteosynthesis is a reliable and feasible technique that yields good clinical outcomes.

Complications and Functional Outcome Following Operative Treatment of Talus Neck and Body Fractures: A Systematic Review.

Background: Central talar fractures are rare and often associated with impaired functional outcome. Despite recent advances in diagnosis and management of talus fractures, complications rates remain high and functional outcome is generally poor. This study aims to provide an overview of complication rates and functional outcome following operative treatment of talar neck and body fractures. This may help in clinical decision making by improving patients' expectation management and tailored treatment strategies. Methods: A systematic review of the literature was conducted of studies published from January 2000 to July 2021 reporting functional outcome and/or complications following operative treatment of talar neck, body, or combined neck and body fractures. Keywords used were (Talar fracture) or (Talus fracture). Data on complication rates and functional outcome was extracted from selected articles. Results: A total of 28 articles were included in our analysis reporting 1086 operative treated talar fractures (755 neck [70%], 227 body fractures [21%], and 104 combined body and neck fractures [9%]). The mean follow-up was 48 (range 4-192) months. Complications occurred frequently with; 6% surgical site infection, 8% nonunion, 29% avascular necrosis, 64% osteoarthritis, and in 16% a secondary arthrodesis was necessary. A wide variety in functional outcome was reported; however, there seems to be a correlation between fracture classification and postoperative complications. Conclusion: Operative treatment of central talar fractures is associated with a high incidence of early and late complications and often leads to an impaired functional outcome. Standardization of talar fracture classification and scoring systems in combination with large sample-sized prospective studies are warranted to detect further predictive factors influencing tailormade treatment strategies and patient expectation management.

Rare Combination of Distal Tibial Physeal Injury (Salter-Harris Type IV) with Sagittal Plane Fracture of Talus Body: A Case Report.

Introduction: Distal tibial physeal fractures and talus fractures are rare injuries in children and adolescents. Even rare is a combination of these two fractures. Axial compression is an accepted mechanism of injury in talus fractures with position of foot at the point of impact determining the extended patterns. A concomitant medial malleolus fracture suggests a supinated foot at the time of impact. Case Presentation: We report a case of a 13-year-old girl child who sustained a Type IV Salter-Harris injury of distal tibial physis along with a displaced vertical (sagittal) type fracture of the talus body. The uniqueness in our case was that the talar body fracture was a vertical type and that too displaced in the same line along with medial malleolus fragment. Open reduction of both the fractures was done through anteromedial approach followed by minimal fixation with K-wires. Good results were observed at 1 year following the surgery. Conclusion: Injuries of this nature are very uncommon and even more unusual in pediatric age group. This case report emphasizes the importance of having a high suspicion of uncommon fracture patterns in pediatric age group. Early and prompt diagnosis should be made using CT/MRI as a lot of these injuries may go unnoticed on plain radiographs.

Dual Approach to Talar Dome Increases Access for Fracture Care Without Osteotomy.

BACKGROUND: There is no consensus surgical treatment algorithm for talar body fractures, with authors recommending both soft tissue-only and osteotomy-based approaches. This study evaluates talar dome access via dual approaches to the talar dome through anterolateral transligamentous (ATL) and modified posteromedial (mPM) approaches. METHODS: Ten cadaveric legs (5 matched pairs) were included. An mPM approach, between flexor hallucis longus and Achilles tendon, and an ATL approach, utilizing the anterolateral interval with transection of anterior talofibular ligament and calcaneofibular ligament, were performed on each specimen. Order of approach was alternated within each pair. Accessible dome surface area (DSA) was outlined by drilling with a 1.6-mm Kirschner wire at the visualized talar dome margin both with and without 4 mm of tibiotalar distraction using an external fixator. Specimens were analyzed by computed tomography (CT). Primary outcome was accessible DSA. Student t tests compared DSA accessed by different exposure methods. RESULTS: An initial mPM approach exposed 25.6% and 33.6% of DSA without and with distraction (P = .002). An initial ATL approach accessed 47.0% and 58.1% of DSA without and with distraction, respectively (P = .003). Accessibility via dual approaches was 71.7% and 93% of DSA without and with distraction with an initial ATL approach and 71.3% and 87.5% of DSA without and with distraction with an initial mPM approach (P = .96 and .37, respectively). The central talar dome was inaccessible in an almond-shaped area, tapered at the medial and lateral ends. Anterior, lateral, and posterior articular margins were able to be fully exposed, often with overlapping exposure between posterior and anterior approaches, with distraction reliably improving lateral visualization. CONCLUSION: Dual approaches provided access to greater than 70% and 85% of talar DSA without and with distraction, respectively. Order of approach did not significantly affect exposure and thus should be determined by surgeon discretion. These results may promote soft tissue-only treatment strategies in talar body fracture care with an extensile exposure of the talar dome surface. Careful preoperative planning optimizes the advantages of this approach. LEVEL OF EVIDENCE: Level IV, case series.

Functional outcome and quality of life in surgically treated talar neck and body fractures; how is it affected by complications.

BACKGROUND: Since talus fractures are rare, study populations are frequently small. The aim of this study is to describe how surgical treatment of talar neck and body fractures and postoperative complications affect functional outcome and quality of life measured by validated questionnaires. METHODS: All patients following surgically treated talar neck and/or body fracture between January 2000 and December 2019 at a level 1 trauma center were included in this retrospective cohort study. Primary outcomes were functional outcomes measured by Lower Extremity Functional Score (LEFS), the Foot Function Index (FFI), and the Quality of Life (QOL) measured by the EuroQol 5-dimension questionnaire (EQ-5D). Linear regression was used to assess the relationship between continuous variables and the outcome, and multivariable linear regression was used to identify the predictors of the functional outcome. RESULTS: Ninety patients were included, of which 73 responded to our questionnaires. The median follow-up time was 50.5 (interquartile range (IQR), 18.3-97.3) months. Our study showed the following results: a mean LEFS of 58.4 (range, 17-80), a median FFI of 15.7 (IQR, 3.5-35.2), a median EQ-5D index score of 0.83 (IQR, 0.81-1.00), a median patient satisfaction of 9.0 (IQR, 8.0-10.0), a patient reported health status of 76.8 (range, 20-100), and a mean AOFAS score of 75.7 (range, 28-100). Implant removal and secondary arthrodesis were associated with a reduced AOFAS outcome score (p=0.001, p<0.001), and implant removal was also a predictive factor for a less favorable LEFS outcome score (p=0.001). CONCLUSION: Patients who underwent implant removal and/or secondary arthrodesis had poorer functional outcome compared to patients who did not undergo additional procedures. Careful consideration of re-intervention must be made in combination with patient expectation management. Future studies should focus on how to lower the rate of complications and the effect of secondary intervention with the use of validated questionnaires.

Talar Dome Access Through Posteromedial Surgical Intervals for Fracture Care.

BACKGROUND: Posterior talar body fractures are rare injuries without a consensus surgical approach. This study evaluates the accessible area of the talar dome through 2 posteromedial approach intervals (posteromedial [PM] and modified posteromedial [mPM]) both with and without distraction. METHODS: Ten male cadaveric legs (5 matched pairs) were included. A PM approach, between flexor hallucis longus (FHL) and the tibial neurovascular bundle, and an mPM approach, between FHL and Achilles tendon, was performed on each pair. In total, 4 mm of distraction across the tibiotalar joint was applied with the foot held in neutral position. Accessible dome surface area (DSA) was outlined by drilling with a 1.6-mm Kirschner wire with and without distraction. Specimens were explanted and analyzed by micro-computed tomography with 3-dimensional reconstruction. Primary outcomes were total accessible DSA and sagittal plane access at predetermined intervals. RESULTS: The PM approach allowed access to 19.1% of the talar DSA without distraction and 33.1% of the talar dome with distraction (P < .001). The mPM approach provided access to 20.4% and 35.6% of the talar DSA without and with distraction (P < .001). Both approaches demonstrated similar sagittal plane access at all intervals except the lateral border of the talus, where the mPM approach provided greater access both without distraction (20.5% vs 4.38%, P = .002) and with distraction (34.3% vs 17.8%, P = .02). CONCLUSION: The mPM approach, using an interval between FHL and Achilles tendon, provides similar access to the posterior surface of talar dome and better sagittal plane access to the most lateral portion of the dome. The mPM interval provides the advantage of avoiding direct dissection of the tibial nerve or posterior tibial artery. Using an external fixator for distraction can improve talar dome visualization substantially. LEVEL OF EVIDENCE: Level V, Cadaveric Study.

The talar body prosthesis treated end-stage ankle arthritis with talar body deficient: a 6-13 years of follow-up outcomes and 6-year survivorship.

INTRODUCTION: Talar body deficient provides a unique challenge for ankle arthritis treatment. We studied the clinical-radiographic outcomes at 6 to 13 years and 6 year prosthesis survivorship of patients treated for ankle arthritis with poor talar body bone stock using a talar body prosthesis (TBP). MATERIALS AND METHODS: Between 2008 and 2015, we treated 32 consecutive end-stage ankle arthritis patients with talar body deficiency by TBP implantation and fascia interposition. One patient was excluded with a diagnosis of inflammatory arthritis. We assessed visual analogue scale (VAS) of ankle pain, sagittal range of motion, American Orthopaedics Foot and Ankle Society (AOFAS) ankle-hindfoot score, Foot Ankle Ability Measure (FAAM) of activity daily living (ADL), prosthesis tibiotalar surface angle, radiographic prosthesis loosening, adjacent joint arthritis and complication. Pre-operative to last follow-up outcomes (at 6-13 years) were compared. Prosthesis survivorship was analyzed at 6 year follow-up. p < 0.05 was considered a significant difference. RESULTS: There was statistically significant improvement of median VAS ankle pain, as 8.0 (IQR 1.0) to 1.0 (IQR 2.0), AOFAS ankle-hindfoot score from 48 (IQR 21) to 80 (IQR 7.0), FAAM of ADL from50.0 (28.0) to 88.0 (IQR 15.0), and sagittal ROM from 20o (IQR 19°) to 33° (IQR 14°), p < 0.05. The median tibiotalar surface angle was statistically significant improved from 85.0° (IQR 8.0°) to 89.0° (IQR 3.0°), p < 0.001. No radiographic prosthesis loosening or adjacent talonavicular-calcaneocuboid joint arthritis. The 6 year prosthesis survivorship was 93.5% (95% CI 84.9-100.0%). End of survivorship was observed in 2 patients due to progressive valgus tilting at 16° and 18°, respectively. No prosthesis was revised. CONCLUSIONS: TBP implantation with fascia replacing the articular end of distal tibia provided significant better pre- to post-operative clinical outcomes and had 6 year survivorship as 93.5% for the treatment of ankle arthritis with talar body deficient.

The King's Sliding Hindfoot Osteotomy for the Treatment of Talus Body Defects-Results of a New Technique in Tibiotalocalcaneal Arthrodesis.

Bone loss after avascular necrosis of the talus secondary to acute traumatic or chronic pathologies often requires surgical reconstruction. This study reports the early results of a sliding oblique hindfoot osteotomy for salvage procedures combined with tibiotalar arthrodesis to achieve a well-aligned, painless, plantigrade foot. All patients presenting to our institution with severe talus body defects requiring corrective surgery between January 2016 and August 2020 were included. An oblique osteotomy of the diseased talus was performed to correct anterior talus subluxation and prevent excessive loss of height at the tibiotalar apposition and to correct varus-valgus deformity. A retrograde hindfoot nail was used for intramedullary tibiotalocalcaneal arthrodesis. Patients were prospectively followed. Primary outcomes included assessment of mobility and union at 6 months. Secondary outcomes included 30-day postoperative complications, patient satisfaction and change in American Orthopaedic Foot & Ankle Society (AOFAS) score at 1-year postoperation. Nine patients underwent this procedure with a mean follow-up of 18 months (4-36 months). Average age was 66 (58-81) years. Mean body mass index was 33.7 (22-38) kg/m2. All patients went on to fusion and were ambulating at 6 months (n = 8). At 1 year, the mean improvement in AOFAS was 28.9 points (p < .05) (n = 7) and all patients were satisfied with the outcome of their treatment. This technique represents an alternative to conventional hindfoot salvage techniques showing predictable outcomes in complex hindfoot deformity with talar body collapse and anterior subluxation. Further quantitative studies are needed to define if this technique minimizes limb shortening/limb-length discrepancies when compared to traditional horizontal cuts.

The lateral transligamentous approach to the talar dome.

INTRODUCTION: Anatomic reduction of talar body fractures is critical in restoring congruency to the talocrural joint. Previous studies have indicated 43% talar body access with a single incision and without malleolar osteotomy. The aim of this study was to investigate the percentage talar body exposure when using the lateral transligamentous approach. METHODS: The lateral transligamentous approach to the talus was undertaken in 10 fresh frozen cadaveric specimens by surgeons inexperienced in the approach following demonstration of the technique. An incision was made on the anterolateral aspect of the ankle augmented by the removal of the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) from their fibular insertions. A bone lever was then placed behind the lateral aspect of the talus and levered forward with the foot in equinus and inversion. A mark was made on the talar dome where an instrument could be placed 90 degrees to the talar surface. The talus was subsequently disarticulated and high-resolution images were taken of the talar dome surface. The images were overlain with a reproducible nine-grid division. Accessibility to each zone within the grid was documented using the mark made on the talar surface. ImageJ software was used to calculate the surface area exposed with each approach. RESULTS: The mean percentage area of talar dome available through the transligamentous approach was 77.3% (95% confidence interval 73.3, 81.3). In all specimens the complete lateral talar process was accessible, along with the lateral and dorsomedial aspect of the talar neck. This approach gives complete access to Zones 1, 2, 3, 5 & 6 with partial access to Zones 4, 8 & 9. CONCLUSION: The lateral transligamentous approach to the talus provides significantly greater access to the talar dome as compared to standard approaches. The residual surface area that is inaccessible with this approach is predominantly within Zones 4,7 and 8, the posteromedial corner. LEVEL OF CLINICAL EVIDENCE: V.

Combined Talus Fracture with Medial Malleolar Fracture: A Case report with Review of Literature.

INTRODUCTION: Combined talar body fracture with a medial malleolar fracture is rare in literature. CASE PRESENTATION: A 30-year-old female presented to our hospital with complaints of pain and swelling over the right ankle joint with difficulty in bearing weight following a motor vehicle accident. Investigation showed talar body fracture of type 2 Sneppen (classification) with an ipsilateral medial malleolar fracture. Fractured talus was openly reduced with the help of reduction clamp and appropriate sized Herbert screw applied to hold the reduction. The medial malleolar fracture was fixed with an appropriate-sized cannulated cancellous screw after confirming satisfactory reduction. The patient was followed up for wound complications, AVN changes, early osteoarthritic changes, and functional outcome. CONCLUSION: The combined talar body fracture, ankle dislocation with a medial malleolar fracture, should be managed; as soon as, a diagnosis is made to get a good functional outcome, even though the incidence of skin complication, AVN risk, and post-traumatic ankle arthritis could not be predicted even though it was absent in our case.

A rare combination of closed fracture of right talar body Sneppen 2 with associated medial malleolus: A case report.

INTRODUCTION: Ankle fractures are common, with the incidence of up to 174 cases per 100,000 adults per year. The talus, the second largest tarsal bone, has distinctive imaging characteristics and injury patterns. The combination of talar body fracture in sagittal plane along with medial malleolus fracture is an unusual pattern of injury and rarely reported in the literature. PRESENTATION OF CASE: We presented a case of nineteen-year old male with pain on the right ankle as a result from motorcycle accident twelve hours before admitted to Cipto Mangunkusumo Hospital. After the patient underwent close reduction and immobilization using back slab, patient then underwent open reduction surgery of the right ankle then fixated using plate and screw combined by tension band wiring (TBW) at the right medial malleolus. DISCUSSION: Talar and Medial malleolus fracture was initially evaluated by physical examination and radiographic imaging and classified by Sneppen classification. After the diagnosis was established the patient underwent ORIF plate, screw and tension band wiring. In post-operative x-ray examination, there was a significant improvement in talocrural angle and medial clear space but same result in tibiofibular overlap and tibiofibular. CONCLUSION: Open reduction and internal fixation (ORIF) plate and screw combined by tension band wiring (TBW) is the right surgical treatment for patient with closed fracture of right talar body Sneppen 2 with associated medial malleolus fracture. The outcome of the treatment is excellent because the patient presented was able to fully recover to normal activity.

Long-term radiographic and clinical-functional outcomes of isolated, displaced, closed talar neck and body fractures treated by ORIF: the timing of surgical management.

BACKGROUND: The main purpose of this retrospective case series study was to evaluate long-term radiographic and clinical outcomes of a consecutive series of patients diagnosed with isolated, displaced, closed talar neck or body fractures treated by open reduction and internal fixation (ORIF). Secondly, the aim was to verify the influence of the location of talar fractures on the outcomes, the prognostic value of the Hawkins sign, whether operative delays promote avascular necrosis (AVN) and if the fractures require emergent surgical management. METHODS: From January 2007 to December 2012, at our institution, 31 patients underwent ORIF through the use of screws. On the basis of Inokuchi criteria, the injuries were divided between neck and body fractures, which were classified according to Hawkins and Sneppen, respectively. The patients included were divided into two groups in relation to fracture location and complexity. Radiographic assessment focused on reduction quality, bone healing, the Hawkins sign and post-traumatic arthritis (PTA) development. For the clinical evaluation, clinical-functional scores (AOFAS Ankle-Hindfoot Score; MFS; FFI-17; SF-36) and VAS were determined, and statistical analysis was performed. RESULTS: 27 patients, 19 males and 8 females, mean age 38.3 years, were included with an average follow-up period of 83.2 months (range 49-119). There were 9 neck and 19 body fractures; their reduction was anatomical or nearly anatomical in 22 cases, and all reached radiographic consolidation after a mean period of 3.4 months (range 1.7-7). The Hawkins sign was observed in 9 cases, in which necrosis did not develop. With a 0-11 day surgical timing interval, more than 60% of the patients obtained good or fair results with different scores, while 18 (66.7%) were completely satisfied (VAS: 9-10). The early complications included malunions (21.4%) and wound problems (25%); the late complications involved AVN (25%) and PTA (78.6%). CONCLUSIONS: Despite a high rate of long-term complications, satisfactory clinical results were achieved. Talar fracture location did not influence the outcomes, the Hawkins sign was confirmed as a positive prognostic factor, and operation timing did not influence AVN development. Hence, these injuries do not require emergent surgical management by ORIF.
