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.
