Concurrent ipsilateral fractures of acetabular posterior wall and femoral shaft associated with posterior hip dislocation: A case report and literature review of a rare injury.

INTRODUCTION: A floating hip injury involving the acetabulum and femur, often complicated by hip dislocation, necessitates a timely and appropriate management strategy to preserve the extremity and patient well-being. CASE PRESENTATION: We present a case of a 20-year-old male with concurrent fractures of the acetabular posterior wall, a comminuted femoral shaft, and posterior hip dislocation. Reduction of the dislocated hip posed a challenge due to the femoral shaft fracture. We successfully employed an innovative technique, using pins proximal and distal to the shaft fracture in conjunction with a temporary external fixator, later replaced by an interlocking nail after hip reduction. Subsequently, we addressed the acetabular fracture through a posterior hip approach, enabling the patient to regain full weight-bearing capacity within a few months. DISCUSSION: In managing concurrent injuries in a floating hip, particularly when a femoral shaft fracture is involved, innovative approaches, such as the one described in this study, are crucial for timely hip reduction. Following hip reduction, a series of surgeries are required to address the multiple lower extremity injuries, prioritizing those with the highest risk of adverse events and neurovascular complications. CONCLUSION: Urgent procedures for multiple fractures in orthopedic trauma surgery are pivotal for the best long-term outcomes. Prioritizing these urgent procedures, even through unconventional transient methods when conventional means are unavailable, can prevent long-term complications such as avascular necrosis. Effective and timely management is paramount for optimal patient recovery.
