Résumé
Sciatic nerve damage is a well-known complication that occurs in 1.5% of patients after primary total hip arthroplasty and in 8% after revision total hip arthroplasty. Yet when considering re-revision arthroplasty and acetabular cage implantation, incidence and management remain unclear. This case report describes a young female patient with sciatic nerve impingement after acetabular cage implantation. Her primary complaint was shooting sciatic left leg pain, worsening on ambulation and when seated. A complete workup was negative for spinal impingement or infection, and axonal nerve damage was confirmed through nerve conduction studies. The intraoperative findings showed that it was the acetabular cage rim that stretched the sciatic nerve. The rim was adjusted using a diamond burr to provide a specific solution without sacrificing the acetabular anchorage. Postoperative findings showed an excellent return to previous mobility and resolution of pain. This case provides a rare example of sciatic nerve impingement, showing that nerve palsies in the revision total hip arthroplasty setting may require patient-specific solutions.
