Clinical Scorecard: Bosworth Ankle Fracture-Dislocation: A Case Study and Review of Existing Literature
At a Glance
Category
Detail
Condition
Bosworth fracture-dislocation, a rare ankle injury involving entrapment of the proximal fibular fragment behind the tibial ridge or posterior malleolus
Key Mechanisms
Entrapment of the proximal fibular fracture fragment behind the posterolateral tibial ridge or posterior malleolar fragment causing difficult closed reduction
Target Population
Patients presenting with ankle trauma, particularly following falls
Care Setting
Orthopedic surgical and radiological care settings
Key Highlights
Bosworth fracture-dislocation is frequently misdiagnosed due to insidious radiographic features.
Closed reduction is often unsuccessful because of fibular entrapment behind the tibia or posterior malleolus.
Intraoperative positioning in a floating position facilitates adequate exposure and fluoroscopic monitoring, reducing reduction failure risk.
Guideline-Based Recommendations
Diagnosis
Confirm diagnosis with clinical history, standard radiographs, and computed tomography imaging.
Maintain high suspicion for Bosworth fracture-dislocation in ankle injuries with deformity and swelling.
Management
Attempt closed reduction initially, but proceed to early open reduction if closed methods fail.
Perform open reduction and internal fixation via a posterolateral approach.
Use a floating intraoperative position to allow better exposure and fluoroscopic imaging.
Monitoring & Follow-up
Use intraoperative real-time fluoroscopic monitoring to confirm reduction.
Obtain standard lateral radiographs intraoperatively to detect persistent fibular entrapment.
Risks
High risk of misdiagnosis leading to delayed treatment.
Risk of failed reduction due to unrecognized fibular entrapment, especially if prone position limits imaging.
Patient & Prescribing Data
Adult patients with Bosworth ankle fracture-dislocation following trauma
Surgical intervention with open reduction and internal fixation is required after failed closed reduction attempts; intraoperative positioning impacts success.
Clinical Best Practices
Maintain a high index of suspicion for Bosworth fracture-dislocation in ankle injuries with deformity and swelling.
Use computed tomography to aid diagnosis when radiographs are inconclusive.
Avoid prone positioning during surgery to enable standard lateral radiographs and better visualization.
Adopt a floating position intraoperatively to facilitate fibular release and stable fixation.
Communicate thoroughly with patients regarding the possibility of revision surgery if initial reduction fails.
