Traumatic proximal tibiofibular dislocation with neurovascular injury

Area of Science:

• Orthopedic Surgery
• Traumatology
• Vascular Surgery

Background:

• Proximal tibiofibular joint dislocations are uncommon injuries.
• Popliteal artery and peroneal nerve injuries often accompany severe knee trauma.
• The simultaneous occurrence of these specific injuries presents a unique clinical challenge.

Purpose of the Study:

• To report a rare case of inferolateral proximal tibiofibular joint dislocation.
• To highlight the associated complex injuries, including popliteal artery and common peroneal nerve damage.
• To document the extension of injury to the interosseous membrane and distal tibiofibular joint.

Main Methods:

• Case report of a 23-year-old male patient.
• Clinical examination and diagnostic imaging (e.g., X-ray, MRI, CT angiography).
• Surgical management of the tibiofibular joint dislocation and vascular/neurological repair.

Main Results:

• Successful reduction of the inferolateral proximal tibiofibular joint dislocation.
• Identification and repair of popliteal artery injury.
• Management of common peroneal nerve injury.
• The injury extended to involve the interosseous membrane and distal tibiofibular joint.

Conclusions:

• This case represents a unique and previously unreported combination of proximal tibiofibular joint dislocation with extensive vascular and nerve compromise.
• Prompt diagnosis and multi-disciplinary surgical intervention are crucial for managing such complex injuries.
• Further research may be warranted to understand the biomechanics and optimal treatment strategies for this specific injury pattern.
