THA achieved functional improvement in patients with SLE, avascular necrosis of the femur head
Among patients who had systemic lupus erythematosus or avascular necrosis of the femur head, total hip arthroplasty was an adequate treatment for achieving functional improvement, according to study results.
Researchers compared the results of 19 total hip arthroplasties (THAs) in patients with systemic lupus erythematosus (SLE) performed between May 1997 and September 2011 with the results of 19 patients in a control group who underwent THA due to avascular necrosis of the femur head. Follow-up occurred at 6 weeks, 3 months, 6 months and 12 months postoperatively and then yearly for a radiologic review. The researchers used Harris Hip Score to evaluate the functional recovery of the hip after THA.
Results showed at most recent follow-up Harris Hip Score for patients with SLE increased from 65.3 points preoperatively to 94.9 points. Harris Hip Score also increased for the control group, from 67.2 preoperatively to 96.1 postoperatively.
The researchers found no significant differences between patients with SLE and those with avascular necrosis of the femur head who underwent THA.
