Abstract
OBJECTIVE The talus is an important component in the ankle, and its treatment after injury is crucial. However, complications and adverse events due to incomplete traditional classifications may still occur, and these classifications fail to analyze the patterns and distribution of fractures from a three-dimensional perspective. Therefore, in this study, we aimed to analyze the location and distribution of fracture lines in different types of talus fractures using three-dimensional (3D) and heat mapping techniques. Additionally, we aimed to determine the surface area of the talus that can be utilized for different approaches of internal fixation, aiding in the planning of surgical procedures. METHODS We retrospectively analyzed data from CT scans from 126 patients diagnosed with talus fractures at our two hospitals. We extracted the CT data of a healthy adult and created a standard talus model. We performed 3D reconstruction using patients' CT images and superimposed the fracture model onto the standard model for drawing fracture lines. Subsequently, we converted the fracture lines into a heat map for visualization. Additionally, we measured 20 specimens to determine the boundary for various ligaments attached to the talus. We determined the surface area of the talus available for different surgical approaches by integrating the boundary data with previously reported data on area of exposure. RESULTS Without considering the displacement distance of the fracture, fracture types were classified as follows, by combining Hawkins and Sneppen classifications: talar neck, 41.3%; posterior talar tubercle, 22.2%; body for the talus and comminuted, 17.5%; lateral talar tubercle, 11.9%; and talar head, 7.1%. We established fracture line and heat maps using this classification. Additionally, we demonstrated the available area for anteromedial, anterolateral, posteromedial, posterolateral, and medial malleolus osteotomy and Chaput osteotomy approaches. CONCLUSION Fracture line and heat map analyses can aid surgeons in planning a single or combined surgical approach for the reduction and internal fixation of talus fractures. Demonstrating the different surgical approaches can help surgeons choose the most effective technique for individual cases.

Abstract
Fractures to the talar neck and talar body (central talar fractures) are rare injuries but often result in devastating outcomes. It is therefore important to diagnose these injuries early and provide the best possible treatment. The analysis, classification, and surgical planning of central talar fractures should be based on computed tomography (CT) imaging. In the case of dislocated fractures, surgeons must strive for an anatomic reduction and fixation. The approach routes are based on the fracture morphology and must enable adequate reduction of the fracture. This can often only be achieved by two or more approach routes. The outcome correlates with fracture complexity and the quality of the reduction. Complications such as avascular necrosis and posttraumatic osteoarthritis are common and have a negative effect on the results of the treatment.

Foot Ankle Surg 2023; 29:118-127. [PMID: 36526523 DOI: 10.1016/j.fas.2022.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 11/28/2022] [Accepted: 12/03/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND The operative treatment of high-grade talar neck fractures remains challenging, despite numerous previous reports. Our goal was to determine long-term outcomes and to establish a plan for management of postoperative complications (especially, avascular necrosis [AVN] of talar body) after high-grade talar neck fractures. We hypothesized that not every case with AVN of talar body require secondary surgical interventions. METHODS We retrospectively reviewed the radiographic and clinical findings of 14 patients who underwent operative treatment for high-grade talar neck fractures (modified Hawkins type III and IV) between January 2000 and December 2017. The minimum follow-up duration for inclusion was 3 years. Using radiographs during follow-up, we assessed the development of AVN of the talar body, malunion, nonunion, and posttraumatic osteoarthritis. Information about the secondary operations and their outcomes were also investigated using visual analogue scale (VAS) and American orthopaedic foot and ankle society (AOFAS) ankle-hindfoot scale at the final follow-up. RESULTS In 10 of 14 patients (71.4 %), talar body AVN developed during follow-up. However, secondary operation was required in only 30.0 % (3 of 10 patients). In the remaining 7 patients who did not undergo secondary operation, the symptoms were tolerable with a maximum of 89 months follow-up; although the talar body presented sclerotic changes, but without talar dome collapse. The rates of malunion and post-traumatic subtalar osteoarthritis were 21.4 % and 14.3 %, respectively. No patients presented with fracture site nonunion. After a mean of 55.86 ± 14.45 months (range, 37-89) follow-up, the final mean VAS and AOFAS scores were 3.07 ± 0.73 (range, 2-4) and 80.43 ± 3.11 (range, 75-85), respectively. CONCLUSION We recommend leaving talar body AVN untouched, unless the patient's symptoms become intolerable. In our clinical practice, postoperative AVN could be stably maintained without talar dome collapse for more than 7 years, although the sclerotic change persisted. Despite the small number of patients, our clinical experience may benefit patients with high-grade talar neck fractures and surgeons who treat such rare, serious, and challenging foot injuries.

A retrospective analysis of the definitive management of open talus fractures at a major trauma centre, comparing ORIF to FUSION: cohort study and audit of BOAST 4 guidelines. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2023; 33:393-400. [PMID: 35031854 PMCID: PMC8759602 DOI: 10.1007/s00590-022-03204-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 01/05/2022] [Indexed: 11/15/2022]
Abstract
PURPOSE Open talus fractures are notoriously difficult to manage, and they are commonly associated with a high level of complications including non-union, avascular necrosis and infection. Currently, the management of such injuries is based upon BOAST 4 guidelines although there is no suggested definitive management, and thus, definitive management is based upon surgeon preference. The key principles of open talus fracture management which do not vary between surgeons are early debridement, orthoplastic wound care, anatomic reduction and definitive fixation whenever possible. However, there is much debate over whether the talus should be preserved or removed after open talus fracture/dislocation and proceeded to tibiocalcaneal fusion. METHODS A review of electronic hospital records for open talus fractures from 2014 to 2021 returned fourteen patients with fifteen open talus fractures. Seven cases were initially managed with ORIF, and five cases were definitively managed with FUSION, while the others were managed with alternative methods. We collected patient's age, gender, surgical complications, surgical risk factors and post-treatment functional ability and pain and compliance with BOAST guidelines. The average follow-up of the cohort was 4 years and one month. EQ-5D-5L and FAAM-ADL/Sports score was used as a patient reported outcome measure. Data were analysed using the software PRISM. RESULTS Comparison between FUSION and ORIF groups showed no statistically significant difference in EQ-5D-5L score (P = 0.13), FAAM-ADL (P = 0.20), FAAM-Sport (P = 0.34), infection rate (P = 0.55), surgical times (P = 0.91) and time to weight bearing (P = 0.39), despite a higher proportion of polytrauma and Hawkins III and IV fractures in the FUSION group. CONCLUSION FUSION is typically used as second line to ORIF or failed ORIF. However, there is a lack of studies that directly compared outcome in open talus fracture patients definitively managed with FUSION or ORIF. Our results demonstrate for the first time that FUSION may not be inferior to ORIF in terms of patient functional outcome, infection rate and quality of life, in the management of patients with open talus fracture patients. Of note, as open talus fractures have increased risks of complications such as osteonecrosis and non-union, FUSION should be considered as a viable option to mitigate these potential complications in these patients.

Epidemiology, classification, treatment and mortality of Talus fractures: An observational study of 1794 talus fractures from the Swedish Fracture Register. Foot Ankle Surg 2022; 28:1444-1451. [PMID: 36028442 DOI: 10.1016/j.fas.2022.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 08/17/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Epidemiological data on talus fractures from large nationwide and multicenter studies are rare. This study aims to describe the epidemiology, fracture classification and treatment regimens of talus fractures in a large adult Swedish population. METHODS This observational study is based on data from the Swedish Fracture Register (SFR) including talar fractures in patients ≥18 with a sustained fracture between 2012 and 2021. Epidemiological data on sex, age, injury date, injury mechanism and type (high or low energy trauma), fracture classification (side, type), initial treatment and mortality were analysed. RESULTS We included 1794 talus fractures (1757 patients, 60 % men). Mean age was 40.3 years (range 18-96), and a biphasic age distribution was seen in women. High-energy trauma caused 33 % of all talus fractures. Of all talus fractures, 817 (45.5 %) were classified as AO/OTA type A fractures (avulsion), 370 (20.6 %) as type B (neck) and 435 (24.2 %) as type C (body). The remaining 172 (9.6 %) talus fractures were not classified/unclassifiable. Men were in the majority in all fracture groups except A1. For type A1-3, B1 and C1-2 fractures, most patients were treated non-operatively; in B2-3 and C3 fractures most patients received operative management. Fracture fixation with screws was the dominating surgical treatment. The overall 30-day mortality was 0.2 %. CONCLUSION Talus fractures are most commonly encountered in young and middle-aged men. In contrast to men, a biphasic age distribution was observed in women. Approximately half of the talus fractures are avulsions. Operative treatment, mostly screw fixation, is performed in more complex fracture configurations (B2, B3 and C3 fractures). LEVEL OF EVIDENCE IV, retrospective observational cohort study.

Abstract
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. Level of Evidence: Level III, Systematic review of case series and case-control studies.
