Open reduction of a total talar dislocation: A case report and review of the literature

Pantalar Intact Dislocation: A Systematic Review

BACKGROUND

This scoping review analyzes the available literature on pure total talar dislocation, focusing on its epidemiology, clinical presentation, imaging techniques, surgical options, rehabilitation protocols, and complications.

METHODS

Following the PRISMA-ScR guidelines, a comprehensive search was conducted across the PubMed, Web of Science, and Scopus databases. The search yielded 185 articles, of which 30 satisfied the inclusion criteria and focused on pure total talar dislocation without fractures. Data from each study were extracted, including patient demographics, injury characteristics, treatment methods, and outcomes.

RESULTS

The studies included case reports, case series, and reviews. Despite the heterogeneity of the studies, the key findings suggest that early reduction, careful wound management, and soft tissue preservation are crucial in minimizing complications such as avascular necrosis (AVN), post-traumatic arthritis, and infection. The long-term outcomes varied, and the risk of AVN remained high, particularly in cases with compromised blood supply to the talus.

CONCLUSIONS

Pure total talar dislocation is a rare and challenging condition with no established management protocol. While talar reimplantation and joint fixation offer promising outcomes in preserving function, the risk of complications, particularly AVN, remains significant. Additional research is necessary to standardize treatment protocols and improve clinical outcomes for this rare but severe injury.

Total Closed Talar Dislocation without Ankle Fracture: A Case Report

We report a case of a 61-year-old female who presented to the emergency room after a fall from stairs. A total closed talar dislocation without talus or ankle fracture was diagnosed. The treating surgeon indicated an open reduction after an unsuccessful attempt at closed reduction. After six months of follow-up, the patient reported mild pain and partial weight-bearing with no discomfort; however, signs of talar avascular necrosis were present on magnetic resonance images and CT scans.

Pantalar dislocation: a rare presentation with review of treatment methods

Pantalar dislocation means the simultaneous dislocation of the talocalcaneal, talonavicular, and tibiotalar joint. It is a rare injury comprising only 3.4% of major talar injuries. Treatment of closed Pantalar dislocation is controversial. However, the aim should be to attain a stable anatomic reduction of the Talus in the ankle joint. To prevent further damage to the skin and neurovascular structures, closed reduction of these dislocations should be performed as soon as possible. We report a case of Pantalar dislocation where we tried to reduce the talus both by closed and open methods but it was not possible to reduce the dislocation until the talonavicular joint was reduced first. Intending to improve the clinical knowledge of Pantalar dislocation, we want to convey our clinical experience and results from this rare dislocation.

Closed Pantalar Dislocation With Checkrein Deformity: A Unique Case Report and Literature Review

Closed pantalar dislocations are a rare variant of an uncommon injury. Pantalar dislocations are typically caused by high-energy trauma resulting in an open injury with associated fracture of the articulating bones. Given its obscurity, the literature on closed pantalar dislocations is scarce, and no standard treatment protocol has been accepted. This case report chronicles the treatment and outcome of a 29-year-old man who presented with a checkrein deformity of all digits after a closed pantalar dislocation with 6-month follow-up. A comprehensive literature review found 28 articles representing 39 patients with closed pantalar dislocations without talar neck or body fractures. Roughly equal numbers of closed and open reduction techniques were performed with avascular necrosis occurring in 7 of 36 patients. Although outcome measures and follow-up were variable, what can be considered a suitable outcome was seen in approximately 83% of patients, with only 3 of 35 requiring a secondary operation. Long-term studies with well-defined outcome measures are needed to adequately predict the prognosis of this rare injury and efficacy of treatment protocols.

Closed Pantalar Dislocations: Characteristics, Treatment Approaches, and Outcomes

Closed pantalar dislocation mainly occurs among male adults aged 20 to 45 years and is usually associated with high-energy trauma, mostly falls (50.0%). The talus dislocates anterolaterally in about 85% of cases. Pure pantalar dislocation is more common (54.7%) than cases with concomitant fractures (45.3%). Ankle fractures are the most common associated fractures, followed by fractures of the talar posterior process. Among 40 reported cases, 24 had successful closed reduction (60%), 11 had unsuccessful closed reduction (27.5%), and 5 underwent open reduction without attempting closed reduction (12.5%). The success rate for closed reduction of closed pantalar dislocation is 68.5% (24/35 cases). Post-traumatic arthrosis occurs in 32.3%. Osteonecrosis occurs less often than previously reported. Infection after closed reduction of pantalar dislocation is very rare except after open reduction and fixation for concomitant talar fractures. Conclusively, closed pantalar dislocations are very rare injuries and may portend a poor prognosis. Urgent talar relocation restores ankle and hindfoot anatomy and reduces pressure on surrounding soft tissues to optimize outcome. A closed reduction maneuver should be attempted initially, followed by urgent open reduction when the talus is not accurately reduced through closed means.

Treatment of closed subtalar joint dislocation: A case report and literature review

Subtalar dislocation is defined as a separation of the talocalcaneal and talonavicular articulations, commonly caused by high-energy mechanisms, which include falls from height, motor vehicle crashes, and twisting leg injuries. The dislocations are divided into medial, lateral, anterior, and posterior types on the basis of the direction in which the distal part of the foot has shifted in relation to the talus. The most common type is medial dislocation resulted from inversion injury. Subtalar dislocation may accompany with other fractures. Physical examination must be performed carefully to assess for neurovascular compromise. Most of the subtalar dislocations can be treated with closed reduction under sedation. If this is not possible, open reduction without further delay should be conducted. After primary treatment, X-ray and computed tomography scan should be performed to evaluate the alignment and the fractures. We report a 37-year-old male patient sustained a subtalar dislocation without any bony injury when he was playing football. The patient was successfully treated by closed reduction, and a good alignment was observed at the last follow-up. The pathogenesis and treatment method of this case were analyzed, and the related literature were reviewed, which provided a reference for future clinical treatment.
