Abstract
Objective
The purpose of this study is to evaluate the short term results of total hip arthroplasty (THA) for avascular necrosis in patients with systemic lupus erythematosus (SLE).
Methods
This is a retrospective case control, matched pair study. Ten patients (15 hips) with SLE and avascular necrosis of the femoral head (AVNFH) underwent THA. Eight patients (12hips) with a minimum follow up of 2 years were reviewed. To determine whether these patients had results similar to those of patients with other diagnosis, we formed a control group of 12 patients who had 12 THA. They were matched for age, sex, BMI, activity, follow-up period, and type of implant with SLE group. The clinical and radiographic results were evaluated by Harris hip score (HSS) and serial radiographic findings, respectively.
Results
There was no complication during the perioperative period. In the SLE group, HHS was from 67.3 preoperatively to 97.7 at last follow-up. In the control group, HHS was from 70.1 preoperatively to 97.8 at last follow-up. On the last roentgenograms, none of acetabular components demonstrated any evidence of migration, tilt, rotation or shedding of metal particles in both groups. All femoral components demonstrated no evidence of subsidence, pedestal, or shedding of metal particles in both groups.
