Maisonneuve Variant Lesion with Proximal Tibiofibular Dislocation

Area of Science:

• Orthopedics
• Sports Medicine
• Traumatology

Background:

• Maisonneuve lesion is a rare ankle fracture, comprising 7% of all such injuries.
• Proximal tibiofibular dislocation is an even rarer variant of the Maisonneuve lesion.

Purpose of the Study:

• To report a unique case of a Maisonneuve variant lesion with proximal tibiofibular dislocation.
• To discuss the clinical presentation, radiological findings, and surgical management of this rare injury.

Main Methods:

• Case report of a 34-year-old male with a sports-related lower limb injury.
• Diagnostic imaging including knee X-ray to evaluate the proximal tibiofibular joint.
• Clinical assessment and limb evaluation for Maisonneuve variant lesion diagnosis.

Main Results:

• Anterolateral subluxation of the proximal tibiofibular joint was identified on knee X-ray.
• No associated fracture signs were observed.
• Diagnosis of Maisonneuve variant lesion with proximal tibiofibular dislocation was confirmed.

Conclusions:

• Proximal tibiofibular dislocation represents an uncommon variant of Maisonneuve lesions.
• Accurate diagnosis requires careful clinical and radiological evaluation.
• Surgical considerations for this specific variant warrant further discussion.
