Ipsilateral Intertrochanteric Fracture with Posterior Dislocation of Hip

Abstract

Introduction: High-energy trauma has increased the incidence of traumatic hip dislocation and dislocation is often associated with fractures. However, a hip fracture-dislocation extending to the ipsilateral femoral trochanter is exceedingly rare and only a few cases have been described. We report a case of irreducible posterior dislocation of the hip with ipsilateral intertrochanteric fracture managed by open reduction and osteosynthesis.

Case report: A 50-year-old male presented with a history of fall from an electricity pole with pain in the left hip and an inability to bear weight on his left lower limb. Radiographs confirmed the presence of posterior dislocation of the left hip with comminuted intertrochanteric fracture on the same side.

Conclusion: Posterior dislocation of the hip with same side inter trochanteric fracture is a rare traumatic entity, with only few case being reported. Literature does not provide any classification for such rare traumatic fracture dislocation. Management of such fracture requires early diagnosis and intervention which can result in good prognosis.
