Isolated Medial Peritalar Dislocation Following High-Energy Trauma: A Case Report.

INTRODUCTION

Peritalar dislocation is a rare injury involving simultaneous disruption of the talocalcaneal and talonavicular joints, usually following high-energy trauma. Early recognition and management are crucial to prevent chronic instability, stiffness, or post-traumatic osteoarthritis. We report a case of peritalar dislocation in a 48-year-old patient.

CASE REPORT: A 48-year-old male sustained an isolated medial peritalar dislocation of the right foot after a road traffic accident. Clinical examination revealed medial displacement with a prominent talar head palpable through a submalleolar laceration. Radiographs confirmed the diagnosis. Under general anesthesia, closed reduction using the boot-puller maneuver was performed, followed by temporary transarticular K-wire fixation and below-knee cast immobilization for 6 weeks. Rehabilitation began after cast removal. At 6-month follow-up, the patient achieved full ankle and foot mobility, pain-free walking, and no signs of instability or complications.

CONCLUSION

Medial peritalar dislocations are uncommon but potentially disabling. Prompt diagnosis, gentle closed reduction, temporary stabilization, and supervised rehabilitation are essential for excellent functional outcomes.
