FEMORAL NECK FRACTURE COMPLICATING ORTHOPAEDIC RELOCATION OF A DISLOCATED HIP: FOUR CASES
2018
Purpose: Fracture-posterior dislocation of the femoral head is an exceptional hip injury. Emergency reduction is required. Relocation into the acetabular cavity of the displaced femoral head may not be feasible. Irreducibility, instability, and more rarely accidental fracture of the femoral neck may also occur. We encountered this latter complication in four patients and report here its frequency and mechanism and propose preventive therapeutic measures.Material and methods: Seventy dislocations and fracture-dislocations of the hip were treated in our unit from March 1997 to February 2003. Among these cases, fourteen hip dislocations were complicated by femoral head fractures. Fracture of the femoral neck occurred during reduction in four. All four cases occurred in men, mean age 49.7 years, who were traffic accident victims (drivers or passengers). There were two Pipkin IV fracture-dislocations and two Pipkin II. The first reduction, achieved under general anaesthesia in an emergency setting, was perform...
