Closed reduction of hip dislocation associated with ipsilateral lower extremity fractures: A case report and review of the literature.

backgroundTraumatic hip dislocation usually occurs following high-velocity trauma. It is imperative that the dislocation be reduced in a timely manner, especially in a closed manner, as an orthopedic emergency. However, closed reduction can hardly be achieved in patients who also have ipsilateral lower extremity fractures. Herein, we focus on hip dislocation associated with ipsilateral lower extremity fractures, excluding intracapsular fractures (femoral head and neck fractures), present an early closed hip joint reduction method for this injury pattern, and review the literature to discuss the appropriate closed reduction technique for this rare injury pattern. CASE SUMMARY: We report a case of a 37-year-old male who sustained a left acetabular posterior wall fracture, an ipsilateral comminuted subtrochanteric fracture and dislocation of the hip. The hip dislocation was reduced urgently in a closed manner using the joy-stick technique with a T-shaped Schanz screw. The fractures were reduced and fixed as a 2nd-stage surgery procedure. At the 17-month postoperative follow-up, the patient had full range of motion of the affected hip.

conclusionClosed reduction of a hip dislocation associated with ipsilateral lower extremity fractures is rarely achieved by regular maneuvers. Attempts at closed reduction, by means of indirectly controlling the proximal fracture fragment or reconstructing the femoral leverage rapidly with the aid of various external reduction apparatuses, were shown to be effective in some scenarios. Mandatory open reduction is indicated in cases of failed closed reduction, particularly in irreducible dislocations.
