Posttraumatic Anterior Hip Dislocation with Ipsilateral Comminuted Intertrochanteric Fracture: A Rare Case Report.

Abstract

Hip joint is a ball and socket type of joint and its anatomic features makes it very stable. However, Incidence of hip dislocation has increased recently due to high energy trauma like road traffic accident, fall from height etc. It is usually associated with fracture of femoral head, neck, shaft and acetabular wall. Association of ipsilateral intertrochantric fracture is exceedingly rare and only a few case reports are available in the literature. We are presenting a rare case report of neglected anterior hip dislocation with ipsilateral comminuted intertrochanteric fracture managed with hemiarthroplasty using long cemented distal press-fit revision stem. A 66-year-old male presented to our outpatient department with history of fall from a tree 22 days back with pain in right hip and inability to bear weight on right lower limb. Radiographs were suggestive of anterior hip dislocation with fracture of ipsilateral comminuted intertrochanteric fracture of right side. Anterior hip dislocation with ipsilateral intertrochanteric fracture is a very rare entity, and only a few case reports are available in the literature. Management includes early open reduction and fixation to achieve optimal outcomes, but doing primary arthroplasty is also a viable option especially in neglected cases as there is high chances of avascular necrosis and secondary osteoarthritis of the hip joint later on.
