Low long term wear observed with multiple sized femoral heads using HXLPE in THA
DALLAS — Femoral heads treated with highly cross-linked polyethylene showed low wear during long-term follow-up, according to a presentation made here at the American Association of Hip and Knee Surgeons Annual Meeting.
To measure head penetration into the highly cross-linked polyethylene (HXLPE), investigators studied 16 patients who received a 28-mm head and 13 patients who received a 36-mm head during total hip arthroplasty. CT scan was taken at 13 years postoperatively, and radiostereometric analysis and radiographs were taken at 4 weeks to 6 weeks, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, 7 years, 10 years and 13 years postoperatively.
Differences in penetration during the study period were measured using a Wilcoxon signed-rank test. The total patient population dwindled during the follow-up to 24 patients at 6 months, 19 patients at 2 years, 17 patients at 3 years, nine patients at 5 years, 10 patients at 10 years and nine patients at 13 years.
