Simultaneous Pantalar Dislocation and Bimalleolar Ankle Fracture.

Area of Science:

• Orthopedic Surgery
• Traumatology
• Sports Medicine

Background:

• Open ankle fracture dislocations are severe injuries requiring prompt surgical intervention.
• Talus dislocation, especially when open, poses significant risks of avascular necrosis and infection.
• Management aims to restore articular congruity and enable functional recovery.

Observation:

• A 17-year-old male sustained a total talus dislocation with an open bimalleolar ankle fracture.
• Initial management involved debridement, irrigation, and closed reduction with internal fixation.
• Follow-up at 21 months revealed functional ambulation without assistive devices.

Findings:

• The patient could walk in regular shoes but experienced moderate sinus tarsi pain during activity.
• Radiographs showed no signs of osteonecrosis or infection.
• Mild talonavicular joint narrowing was noted on the final radiograph.

Implications:

• Reimplantation and fixation of pantalar dislocation can achieve acceptable functional outcomes.
• Long-term monitoring is essential to detect joint degeneration and manage residual pain.
• This case highlights successful management of a severe ankle injury in a young athlete.
