Abstract:
BACKGROUND:There are numerous laboratory reports concerning β-tricalcium phosphate (β-TCP) bioceramics;however, its application in the treatment of osteonecrosis of the femoral head (ONFH) is rarely reported. OBJECTIVE:To analyze the short-term efficacy of core decompression combined with β-TCP bioceramics in the treatment of ARCO Ⅰ/Ⅱ/ⅢA non-traumatic ONFH. METHODS:Twelve patients (16 hips) suffered from ARCO Ⅰ/Ⅱ/ⅢA non-traumatic ONFH were treated by core decompression combined with β-TCP implantation. The Harris hip scores (HHS) and radiological observation were performed before and after treatment. The HHS at the last follow-up or the HHS prior to the radiographs showing deterioration or severe complication occurrence was recorded. RESULTS AND CONCLUSION:Al patients were followed up for 19 months averagely (11-30 months) and no fracture, infection and other complications occurred. The HHS significantly increased from (73.61±3.70) to (84.88±7.11) points after treatment (P<0.001). The postoperative outcome was excellent in five cases with five hips, good in five cases with nine hips, mild in one case with one hip, poor in one case with one hip, and the excel ent and good rate was 87.5%(14/16). The radiographs of only one case of ARCO ⅡC and one case of ARCO ⅢA showed deterioration, and the latter was given the total hip arthroplasty. These results indicate that the core decompression combined with β-TCP implantation achieve short-term efficacy for ARCO Ⅰ/Ⅱ/ⅢA non-traumatic ONFH.
