Posterior Hip Dislocation Associated with Posterior Wall Acetabular Fracture and Ipsilateral Intertrochantric Fracture: a Very Rare Case Report

Traumatic hip dislocations are common in high-energy motor vehicle accidents. We present a case of a 43-year old man who sustained posterior hip dislocation with posterior wall acetabular fracture and ipsilateral intertrochantric fracture following a motorcycle accident. Urgent open reduction and internal fixation of the hip fracture-dislocation and fixation of intertrochantric fracture with a dynamic hip screw were done. To our knowledge, such an injury has been rarely reported in the literature. Possible mechanisms of injury and operative procedures are discussed. Radiographic follow-up after eight months showed union. No major complications were observed in our patient.
