Anterior Hip Dislocation with Ipsilateral Subtrochanteric Femur Fracture in a Young Adult - A Rare Case Report.

Introduction: Combined subtrochanteric femur fracture with anterior dislocation of hip is a very rare injury to occur with subminimal reported cases available in the literature. This study report describes one such unusual case presentation.

Case Report: A 26-year-old gentleman presented to our emergency room following road traffic accident, complained of severe pain over his right hip and inability to move his right lower limb. The hip was diffusely swollen and the lower limb externally rotated, clinical and radiological evaluation revealed anterior dislocation of the right hip with ipsilateral subtrochanteric femur fracture. Emergency closed reduction of the right hip was performed using joystick maneuver with two Schanz pins and concomitantly the subtrochanteric fracture reduced, and uniplanar external fixator was applied on the same day of presentation. Following 2 days, external fixator removal and IMIL nailing were performed as an elective definitive procedure. The patient was regularly followed up both clinically and radiologically from the index procedure until now with 2 years as follow-up.

Conclusion: Anterior hip dislocation with ipsilateral subtrochanteric femur fracture in a young adult requires early emergency evaluation and rapid intervention (reduction within 6 h) and early closed reduction of the joint helps decreasing the risk of complications such as avascular necrosis and chondrolysis and joint reduction with fracture fixation allows early rehabilitation.
