esults can be achieved with FINE total ankle arthroplasty system. However, this series wasshort term of follow-up. We need to evaluate mid- and long- clinical results. Mobile bearingtotal ankle arthroplasty is a treatment option for RA and OA.FiguresThursday, October 7, 2010, 8:00-8:50Session A1: Alternate Bearings in THA 1Third Generation Ceramic-on-Ceramic Total Hip Arthroplasty in PatientsYounger Than 30 Years With Avascular Necrosis of Femoral Head: AMinimum 4-Year Follow-Up*Yoon Taek Rim - Chonnam National University - Hwasun-Gun, KoreaPark Kyung Soon - Chonnam National University - Hwasun-Gun, KoreaPark Young Hoon - Chonnam National University - Hwasun-Gun, KoreaCho Nam Young - Chonnam National University - Hwasun-Gun, Korea*Email: tryoon@chonnam.ac.krPurpose: The purpose of this study is to evaluate the functional and radiographical results inpatients younger than 30 years who underwent cementless third generation ceramic-on-ceramictotal hip arthroplasty (THA) for avascular necrosis (AVN) of femoral head.Materials and Methods: Forty one patients (55 hips) with a minimum 4-year follow-up wereincluded in this study. There were 26 men and 15 women with a mean age of 25.6 years (range,16 to 29 years). The average duration of follow-up was 5.7 years (range, 4.0 to 6.5 years). Allsurgeries were done by a single hip surgeon and third generation ceramic-on-ceramicarticulation was used. Functional results were measured by Harris hip score (HHS) andWOMAC score. Radiographic evaluation was assessed for loosening and osteolysis accordingto Gruen’s and Delee and Charnley’s criteria.Results: The average HHS improved from 53 preoperatively to 95 at last follow-up andWOMAC score improved from 72 to 25. Thirty nine patients (51 hips) are continuing theirnormal occupation. There was no aseptic loosening or osteolysis and no prosthesis had beenrevised. There was one patient who complained of continuous squeaking and two patients withBrooker grade I heterotopic ossification. There were no other major complications.Conclusions: THA with third generation ceramic-on-ceramic bearings for AVN of femoralhead especially in active and very young patients results in satisfactory clinical and radiologicalresults at minimum 4 year follow-up. If long tem follow-up shows excellent results, then thefile:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
