Results of total hip replacement in systemic lupus erythematosus
Insights
Total hip replacement surgery in patients with systemic lupus erythematosus (SLE) and avascular necrosis of the femoral head showed excellent outcomes. Most patients experienced successful results with minimal complications, indicating a viable treatment option.
Area of Science:
- Orthopedic Surgery
- Rheumatology
- Immunology
Background:
- Systemic lupus erythematosus (SLE) is an autoimmune disease that can lead to avascular necrosis (AVN) of the femoral head.
- AVN of the femoral head in SLE patients often necessitates total hip replacement (THR).
Purpose of the Study:
- To evaluate the outcomes of total hip replacement (THR) in patients diagnosed with systemic lupus erythematosus (SLE).
- To assess the efficacy and complication rates of THR for avascular necrosis of the femoral head in an SLE cohort.
Main Methods:
- A retrospective review of ten total hip replacements performed between June 1984 and May 1989.
- The study included six patients with systemic lupus erythematosus (SLE) and avascular necrosis of the femoral head.
- Follow-up assessments utilized Mayo clinical hip ratings, with a mean follow-up period of 3.9 years.
Main Results:
- Nine out of ten hips (90%) achieved excellent Mayo clinical hip ratings.
- The mean age of patients at the time of surgery was 31.2 years.
- Complications were infrequent, including one case of transient sciatic nerve palsy and one instance of aseptic loosening of the femoral component.
Conclusions:
- Total hip replacement (THR) is a highly effective surgical intervention for avascular necrosis of the femoral head in patients with systemic lupus erythematosus (SLE).
- The procedure demonstrates a favorable success rate and acceptable complication profile in this specific patient population.
Abstract:
Ten total hip replacements were performed between 1 June 1984 and 31 May 1989 in 6 patients who had systemic lupus erythematosus. All had avascular necrosis of the femoral head. The mean age at operation was 31.2 years with a range of 21 - 41 years. The mean follow-up period was 3.9 years with a range of 1.75 to 6.25 years. Mayo clinical hip ratings were excellent for all but one hip. Complications included transient sciatic nerve palsy in one hip and aseptic loosening of the femoral component in another.
