UNASSIGNED: This study aims to report the midterm outcomes after surgical treatment of Hawkins Classification III Talar neck fractures.
UNASSIGNED: From March 2010 to April 2022, among a total of 155 patients who visited our hospital with talus fractures, 31 patients underwent surgical treatment for Hawkins classification III talar neck fractures. The inclusion criteria comprised patients with a symptom duration of over 1 year who were available for outpatient follow-up and underwent magnetic resonance imaging (MRI) follow-up 2 months after surgery. Exclusion criteria included patients without preoperative ankle periarticular arthritis, and a total of 27 patients were enrolled. Traffic accidents and falls accounted for 86% of 23 cases, open fractures were 8 cases, and the mean follow-up period was 34.10 months (range, 12-80 months). Clinical outcomes were measured by American Orthopaedic Foot and Ankle Society (AOFAS) score and Foot function index (FFI), and radiological results were obtained using simple radiographs before and after surgery and MRI at 2 months postoperatively to confirm bone union and complications.
UNASSIGNED: Complete bone union was achieved in all cases, and the mean duration of union was 4.9 months (range, 4-6 months) and there were no nonunion and varus malunion. At the final follow-up, the mean AOFAS score was 80.18 points (range, 36-90 points) and the mean FFI score was 31.43 points (range, 10-68 points), showing relatively good clinical outcomes. There were 15 cases of avascular necrosis, 6 cases of traumatic arthritis of the ankle joint, 6 cases of irritation of the posterior tibial nerve, and 4 cases of wound problems.
UNASSIGNED: Hawkins classification III talar neck fractures are mostly caused by high-energy injuries and have a relatively poor prognosis due to the high incidence of complications such as avascular necrosis or posttraumatic arthritis. However, if correct anatomical reduction and rigid internal fixation are performed within a short time after the injury, good results can be expected.

BACKGROUND: Talus fractures are often result of high energy mechanisms and can lead to devastating complications. Treatment is often operative; however, the appropriate timing of this has been debated. The purpose of this study is to determine the efficacy and safety of the early treatment of talus fractures.
METHODS: Patients aged 18 years or older who underwent definitive operative stabilization of their talus fracture at a single urban level 1 trauma center were retrospectively reviewed. Patients were split into 2 groups based on their time to definitive fixation: ≤ or >24 hours. Pertinent demographic, surgical, and follow-up data were collected and analyzed.
RESULTS: A total of 108 fractures were treated with 65 in the ≤24 hours fixation group and 43 in the >24 hours fixation group. Fractures involving the talar neck were the most commonly treated fracture pattern followed by the body and the head. There was no difference between the 2 groups in length to full weight bearing, union, or time to union. Open fracture was found to be the only significant risk factor for nonunion in both groups. There was no significant difference in infection or arthrodesis rates between the 2 groups.
CONCLUSIONS: Definitive treatment of talus fractures within 24 hours from presentation is both safe and effective with equal outcomes and without increased complications when compared with those injuries that undergo delayed or staged definitive fixation.
UNASSIGNED: Level III.

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.

UNASSIGNED: To explore the effectiveness of the percutaneous parallel screw fixation via the posterolateral \"safe zone\" for Hawkins type Ⅰ-Ⅲ talar neck fractures.
UNASSIGNED: A retrospective analysis was conducted on the clinical data from 35 patients who met the selection criteria of talar neck fractures between January 2019 and June 2021. According to the surgical method, they were divided into a study group (14 cases, using percutaneous posterolateral \"safe zone\" parallel screw fixation) and a control group (21 cases, using traditional open reduction and anterior cross screw internal fixation). There was no significant difference in gender, age, affected side, Hawkins classification, and time from injury to operation between the two groups ( P>0.05). The operation time, bone healing time, complications, and Hawkins sign were recorded, and the improvement of pain and ankle-foot function were evaluated by visual analogue scale (VAS) score and American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score at last follow-up. The overall quality of life was assessed by the short form of 12-item health survey (SF-12), which was divided into physical and psychological scores; and the satisfaction of patients was evaluated by the 5-point Likert scale.
UNASSIGNED: The operation time in the study group was significantly shorter than that in the control group ( P<0.05). All patients werefollowed up 13-35 months, with an average of 20.6 months; there was no significant difference in the follow-up time between the two groups ( P>0.05). The time of bone healing in the study group was shorter than that in the control group, and the positive rate of Hawkins sign (83.33%) was higher than that in the control group (33.33%), and the differences were significant ( P<0.05). In the control group, there were 2 cases of incision delayed healing, 7 cases of avascular necrosis of bone, 3 cases of joint degeneration, 1 case of bone nonunion, and 3 cases of internal fixation irritation; while in the study group, there were only 2 cases of joint degeneration, and there was a significant difference in the incidence of complications between the two groups ( P<0.05). At last follow-up, there was no significant difference in VAS score between the two groups ( P>0.05), but the SF-12 physical and psychological scores, AOFAS ankle and hindfoot scores, and patients\' satisfaction in the study group were significantly better than those in the control group ( P<0.05).
UNASSIGNED: The treatment of Hawkins type Ⅰ-Ⅲ talar neck fractures with percutaneous parallel screw fixation via the posterolateral \"safe zone\" can achieve better effectiveness than traditional open surgery, with the advantages of less trauma, fewer complications, faster recovery, and higher patient satisfaction.

UNASSIGNED: 回顾分析2019年1月—2021年6月收治且符合选择标准的35例距骨颈骨折患者临床资料。根据手术方式分为研究组（14例，采用经皮后外侧“安全区”行平行螺钉内固定）和对照组（21例，采用传统切开复位前路交叉螺钉内固定）。两组患者性别、年龄、侧别、骨折Hawkins分型及受伤至手术时间等基线资料比较差异均无统计学意义（ P>0.05）。记录两组患者手术时间、骨愈合时间、并发症发生情况及Hawkins征情况；末次随访时采用疼痛视觉模拟评分（VAS）及美国矫形足踝协会（AOFAS）踝与后足评分评价患者疼痛及功能改善情况；采用健康调查12项简表（SF-12）评分评估整体生活质量，分为躯体及心理两部分评分；采用5分李克特量表法对患者满意度进行评价。.
UNASSIGNED: 研究组手术时间短于对照组，差异有统计学意义（ P<0.05）。所有患者均获随访，随访时间13～35个月，平均20.6个月；两组随访时间比较差异无统计学意义（ P>0.05）。研究组骨愈合时间显著短于对照组，Hawkins征阳性率（83.33%）显著高于对照组（33.33%），差异均有统计学意义（ P<0.05）。对照组术后发生切口延迟愈合2例、骨缺血性坏死7例、关节退变3例、骨不连1例、内固定物激惹3例，研究组仅发生2例关节退变，两组并发症发生率比较差异有统计学意义（ P<0.05）。末次随访时，两组VAS评分比较差异无统计学意义（ P>0.05），但研究组SF-12躯体和心理评分、AOFAS踝与后足评分以及患者满意度均优于对照组，差异有统计学意义（ P<0.05）。.
UNASSIGNED: 经后外侧“安全区”行平行螺钉内固定治疗HawkinsⅠ～Ⅲ型距骨颈骨折可获得比传统开放手术更好的临床疗效，具有创伤小、并发症少、恢复快、患者满意度高的优势。.

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.
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.
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).
We found a higher rate of AVN, subsequent collapse, and nonunion in patients with TNPE compared to isolated TN fractures.
Level III, retrospective cohort study.

UNASSIGNED: Talus fractures are extremely uncommon, accounting for approximately 1 % of foot and ankle fractures. The talar neck fracture has a high probability of damaging the anastomotic ring, which would interrupt blood circulation to talar body and cause serious issues with fracture healing and integrity. Due to insufficient radiological and clinical examination, approximately 39 % of midfoot and ankle fractures could be undiagnosed after initial evaluation. Talus fractures account for about half of these missed fractures. Anatomic reduction and advanced fixation methods can be performed in the management of neglected talus neck fracture for the purpose of improving functional outcome.
UNASSIGNED: A 30-year-old male patient presented with swelling and pain on the right foot while walking for three months. He had previously fallen about two meters from stairs three months back. Instead of going to the hospital, he received conventional massage therapy. Three months later, he came to us complaining of chronic, dull aching, swelling, and continuous pain when walking and standing. After radiology evaluation, the patient was diagnosed with neglected nonunion type III Hawkins fracture of the neck talus and managed by double incision approach, Iliac crest cancellous bone graft, open reduction and internal fixation (ORIF) with cannulated screw. He was able to return to full weight bearing and his previous activity without experiencing any pain after 14 months.
UNASSIGNED: Open reduction and internal fixation (ORIF) with Iliac crest cancellous bone graft is a reliable methods for neglected non-union type III Hawkins fracture of neck talus with great functional outcomes after 14 months of follow up.

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.
CONCLUSIONS: 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.
METHODS: Level IV, Case series.

UNASSIGNED: This study evaluated the union rate of talar neck fractures with substantial bone defects treated acutely with autologous tibial bone graft during primary osteosynthesis.
UNASSIGNED: A case series at a level 1 trauma center was performed to identify consecutive patients who underwent operative fixation of talar neck fracture with autograft (Current Procedural Terminology codes 28445 and 20902) between 2015 and 2018. \"Substantial bone defect\" was defined as a gap greater than 5 mm in the sagittal plane and greater than one-third of width of the talar neck in the coronal plane. Postoperative foot computed tomographic (CT) scans were obtained for all patients. Primary outcome was union, and secondary outcomes were malunion, avascular necrosis (AVN), post-traumatic arthritis (PTA), and patient-reported outcomes (PROs).
UNASSIGNED: Twelve patients with 12 fractures were included in the series, with an average length of follow-up of 26 months (range: 7-55) The average age was 34 years (17-59), and the most common mechanism of injury was motor vehicle crash. The Hawkins classification of the fractures was 4 type II (2 type IIA and 2 type IIB) (33%) and 8 type III (67%). Four fractures (33%) were open fractures. Union was achieved in 11 patients (92%). There was 1 malunion (8%). AVN was identified on postoperative CT scans in 11 patients (92%). Three of these 11 eventually showed collapse. Ten patients (83%) had radiographic evidence of some degree of ankle PTA, and 12 patients (100%) had radiographic evidence of some degree of subtalar PTA. Average Patient-Reported Outcomes Measurement Information System-Short Form score was 37 (32-45) and average Foot and Ankle Ability Measure activities of daily living and sports subscale scores were, respectively, 61 (31-87) and 31 (0-71), respectively. Average visual analog scale score was 5 (0-10), and average Foot Function Index was 49 (7-89). SF-36 scores showed fair to poor outcomes in the majority of patients.
UNASSIGNED: In this relatively small series, tibial autograft in primary osteosynthesis of comminuted talar neck fractures with substantial bone defects is associated with excellent union rates and low malunion rates. Despite high union rates, secondary outcomes of AVN with or without collapse, ankle and subtalar PTA, and relatively low PROs were common.
UNASSIGNED: Level IV: Case series.

UNASSIGNED: Talus fracture is an uncommon fracture that can be encountered on day- to- day basis. However, it is the 2nd most common tarsal bone to get fractured after calcaneum and accounts for approximately 1% of all fractures around foot and ankle. The anastomotic ring around the talar neck is highly likely to get damaged at the time of the fracture, which, in turn, hampers the blood supply to the body of talus. As a result, the bone healing is delayed and the integrity of the healed fracture is poor which leads to poor functional outcome. Almost 39% cases are missed during the initial evaluation, and talus fracture accounts for almost 50% of all the missed injuries (6-8). A high level of clinical suspicion is required to avoid missing such injuries.
UNASSIGNED: A 26-year-old male presented to the outpatient department with chief complaint of pain over the left foot while walking for past 6 months. There was a history of significant trauma to the foot 6 months back (fall from 12 feet) for which he sought medical advice and was managed with analgesics and rest for a couple of weeks. He presented to us 6 months later with chronic, dull aching, and continuous pain which aggravates while walking and standing. The diagnosis of the non-union fracture neck of talus was made after radiology and was managed by open reduction and internal fixation with cannulated cancellous screws along with contralateral iliac crest cancellous bone grafting.
UNASSIGNED: Delay in diagnosing such injuries accelerates the vascular compromise, delays timely intervention, and ultimately leads to increased morbidity.

Talus fractures are severe injuries typically occurring after high-energy trauma. As a result, associated injuries to different anatomic sites and organ systems occur with high frequency. The objective of this study was to determine what injuries occur with high incidence in patients presenting with major fractures of the talus and to identify clinical injury patterns that may warrant special attention in these patients.
We performed a retrospective review of patients presenting to 3 level 1 trauma centers with fractures of the talar neck, body, or head over a 14-year period. Patient charts were reviewed for associated orthopedic and nonorthopedic injuries identified during the initial patient encounter and hospitalization.
In total, 262 fractures in 258 unique patients met criteria for inclusion. Overall, 33.3% of talus fractures occurred in isolation. One or more associated injuries were identified in the remainder of cases (66.7%). The incidence of associated injuries was similar across fracture patterns. Mean total number of injuries per patient was 2.2 (range, 0-15). The ipsilateral foot was the most frequent site of associated orthopedic injury. Noncontiguous injuries occurred in 36% of cases. Lumbar spine injury occurred in 10.5% of cases. Lower extremity vascular injury was uncommon but bore significant association with open talus fractures.
Talus fractures are commonly associated with injuries to different anatomic sites and organ systems. A similar rate of lumbar spine trauma may occur with major talus fractures as has been historically associated with calcaneal fractures. Thorough evaluation and a high index of suspicion are necessary when evaluating patients with major fractures of the talus to avoid missing concomitant injuries.
