骨水泥型人工股骨头置换治疗高龄不稳定型股骨转子间骨折

背景：较多研究认为，人工关节置换在高龄骨质疏松、骨折呈现粉碎性、预计无法内固定或内固定失败的病例治疗中有较大优势。 目的：分析骨水泥型人工股骨头置换治疗高龄不稳定股骨转子间骨折的疗效。 方法：纳入18例股骨转子间不稳定型骨折患者，年龄>75岁，均进行骨水泥型人工股骨头置换治疗，置换后3个月按髋关节功能Harris评分法评估疗效，随访观察置换后的早期并发症及假体远期并发症情况。 结果与结论：18例患者随访13-34个月，均未出现感染、压疮、股骨干骨折等并发症，X射线片显示骨折愈合好，无假体感染、脱位、松动、明显下沉、折断等并发症。置换后3个月，所有患者基本恢复至伤前行走功能水平，疗效为优8例，良7例，可2例，差1例。结果表明骨水泥型人工股骨头置换治疗高龄股骨转子间不稳定骨折具有良好的生物相容性及稳定性，可恢复患者肢体功能。  中国组织工程研究杂志出版内容重点：生物材料；骨生物材料; 口腔生物材料; 纳米材料; 缓释材料; 材料相容性；组织工程

Cemented artificial femoral head arthroplasty treats elderly unstable intertrochanteric fracture

BACKGROUND: Many studies have suggested that artificial joint replacement has a greater advantage in the treatment of cases of elderly osteoporosis, comminuted fractures and unable to internal fixation or failure of internal fixation. OBJECTIVE: To analyze the curative effect of cemented artificial femoral head arthroplasty for treatment of elderly unstable intertrochanteric fracture. METHODS: Totally 18 patients with unstable intertrochanteric fracture, aged > 75 years, were enrolled and underwent cemented artificial femoral head arthroplasty. At 3 months after replacement, the curative effect was evaluated according to the Harris hip joint function score method. The early complications after replacement and long-term complications of prosthesis were observed by follow-up. RESULTS AND CONCLUSION: All these 18 patients were followed up for 13 to 34 months, and had no infections, pressure sores, femoral shaft fractures and other complications. X-ray films showed that the frauture healed well, without prosthesis infection, dislocation, loosening, sinking and breaking. After 3 months of replacement, all patients returned to pre-injury level of walking function. The curative effect was excellent for eight cases, good for seven cases, fair for two cases, poor for one case. These results demonstrate that cemented artificial femoral head arthroplasty for treatment of elderly unstable intertrochanteric fracture has good biocompatibility and stability, and can restore the limb function of patients.
