  • IMPLANTATION OF CALCIUM PHOSPHATE CEMENT/DANSHEN DRUG DELIVERY SYSTEM FOR AVASCULARNECROSIS OF FEMORAL HEAD

    【Abstract】 Objective To introduce a new method using calcium phosphate cement/Danshen drug del ivery systemfor avascular necrosis of femoral head and to evaluate its cl inical outcome. Methods From May 2000 to June 2005, 48 patients (54 hips) with avascular necrosis of femoral head were treated with calcium phosphate cement/Danshen drug del ivery system implantation in the involved femoral head. There were 32 males(36 hips) and 16 females(18 hips) with an average age of 38.7 years (26-62 years). Twenty-one cases had the history of drinking or smoking, 15 cases had the history of receiving hormonotherapy and 2 had the history of injury in hip joint. The disease course was 2-32 months. According to standard of Association Research Circulation Osseous (ARCO) staging, 9 hips were classified as stage I, 31 as stage II and 14 as stage III. The operation consisted of removal of necrotic bone under weight-loading cartilage and the implantation of calcium phosphate cement/Danshen drug del ivery system, all mani pulations were done through a bone tunnel in trochanter. The function of hi p joint were evaluated and X-ray films were taken pre- and post-operatively. Results No phlebothrombosis of leg and foreign body action occurred in all cases, and incision healed by first intention. The postoperative follow-up averaged 42.5 months, ranging from 22 to 73 months. According to the evaluation criterion of Dandong 1995 for adult avascular necrosis of femoral head, the results were excellent in 33 hi ps, good in 17, fair in 3 and poor in 1, the excellent and good rate was92.6 %. Conclusion This method is relatively simple with less invasion, it not only improves the microcirculation of femoral head by local appl ication of traditional Chinese medicine, but also provide mechanic buttress in the weight-loaded area, which is beneficial to repair and reconstruction of femoral head. It may be a choice of minimally invasion surgery for femoral head necrosis.
