Shah Medical College and Hospital, Saurashtra University, Gujarat, India Corresponding Author: Dr. Pallav Sandip Mehta 3rd Year Resident Doctor, Department of Orthopaedics, C.U. Shah Medical College and Hospital, Saurashtra University, Gujarat, India A case report of lateral subtalar dislocation Dr. Pallav Sandip Mehta, Dr. Kabir Desai and Dr. Shreyas Gandhi DOI: https://doi.org/10.22271/ortho.2022.v8.i2e.3159 Abstract Introduction: Subtalar or peritalar dislocation is defined as simultaneous dislocation of talocalcaneal and talonavicular joint. Most injuries are caused by moderate to high energy trauma including motor vehicle accidents and falls from height. This case is operated for lateral subtalar dislocation treated with open reduction. Case: A 35 year old male patient came to Emergency Department of C U Shah Medical College And Hospital, Surendranagar with complaints of pain and tenderness over left ankle after history of road traffic accident between patient and bike. On clinical examination, it revealed tenderness and eversion deformity of the foot. Dorsalis pedis and Posterior Tibial pulses were intact. Sensation in the foot was preserved. Conclusion: Subtalar dislocations are rare but serious injuries of the talus this injury is usually due to high energy trauma. Early diagnosis and urgent reduction are the prerequisites for a satisfactory functional outcome. The prognosis is generally good, although long-term monitoring is required to combat the appearance of subtalar arthrosis. Keywords: Subtalar dislocation, talocalcaneal joint, talonavicular joint, arthrosis Introduction Subtalar or peritalar dislocation is defined as simultaneous dislocation of talocalcaneal and talonavicular joint. Most injuries are caused by moderate to high energy trauma including motor vehicle accidents and falls from height. Subtalar dislocations without associated fracture are rare because of the inherent instability of these types of injuries. Subtalar dislocation occurs most commonly in the medial direction followed by lateral, posterior and anterior directions. Case: A 35-year-old male patient came to Emergency Department of C U Shah Medical College And Hospital, Surendranagar with complaints of pain and tenderness over left ankle after history of road traffic accident between patient and bike. On clinical examination, it revealed tenderness and eversion deformity of the foot. Dorsalis pedis and Posterior Tibial pulses were intact. Sensation in the foot was preserved.
