[Recent traumatic peroneal tendon dislocation: a case report].

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Anatomy

Background:

• Peroneal tendon dislocation is a rare condition involving displacement of the peroneal tendons from the retro-malleolar groove.
• It is predominantly caused by trauma and often presents in emergency settings.
• Surgical management is the primary treatment approach for this condition.

Observation:

• A case of a 24-year-old adult with a closed right ankle trauma, forced into a varus and supine position, is presented.
• Initial diagnosis was a benign ankle sprain, but peroneal tendon dislocation was confirmed 14 days later.
• Intraoperative findings revealed a Type II retinaculum rupture according to Eckert and Davis classification.

Findings:

• A simple suture technique, the Exner method, was employed for surgical repair.
• The patient achieved good functional results 14 months post-surgery.
• The case highlights the importance of considering peroneal tendon dislocation in the differential diagnosis of ankle injuries.

Implications:

• This case underscores the diagnostic challenges in differentiating peroneal tendon dislocation from ankle sprains.
• It emphasizes the necessity of surgical intervention for recent peroneal tendon dislocations.
• The successful outcome with the Exner method suggests its efficacy for retinaculum repair in such injuries.
