OBJECTIVE: Patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and ankylosing spondylitis (AS) often require total hip arthroplasties. We present a retrospective review of 32 total hip arthroplasties (THA) performed for patients with SLE, RA or AS from 2003 to 2008 in a tertiary hospital in Singapore.
MATERIALS AND METHODS: A total of 323 THAs performed between January 2003 to December 2008 were traced and cases of arthroplasties performed for such patients were isolated. Pre- and post-operative range of motion, Harris hip score, limb length discrepancies and complications were studied.
RESULTS: Twenty-six patients aged 24-66 years (mean 47 years) were reviewed, with two AS patients (7.7%), 16 RA patients (61.5%), seven SLE patients (26.9%) and one patient (3.8%) with both RA and SLE. Thirty-two THA operations were conducted with six patients requiring bilateral THAs. The average follow-up was 3.3 years. Mean Harris hip score for 25 patients (one excluded due to patient expiry 2 month post-surgery) improved from 41.3 to 86.53 (P < 0.05). Mean pre-operative hip flexion improved from 61.3 degrees (0-120) to 89.7 degrees (30-120) (P < 0.05). Seventeen cases had preoperative limb length discrepancies (median 1 cm) which were all corrected. There were no implants loosening, infective arthritis, dislocations or neurovascular injuries documented.
CONCLUSION: Our series demonstrated the excellent outcome of THA for patients with chronic autoimmune arthropathies at the time of follow-up. Careful patient selection remains a priority as long-term outcomes for such patients of a significantly younger population is yet to be determined.
