目的探讨后路伤椎椎弓根螺钉系统固定结合椎体内植入复合骨治疗胸腰椎骨折的临床疗效。方法选取2009年6月至2011年5月间在我院进行治疗的56例胸腰椎骨折患者,按入院顺序分为对照组和治疗组,每组28例。结果 1年后,治疗组的椎体前缘高度、Cobb角改善程度明显优于对照组,差异有统计学意义。治疗组的腰背痛发生率和内固定失败率均明显低于对照组,差异有统计学意义。结论后路伤椎椎弓根螺钉系统固定结合椎体内植入复合骨治疗胸腰椎骨折的临床疗效良好。
Objective To investigate the efficacy of total hip arthroplasty to treat the avascular necrosis of femoral head(ANFH).Methods Retrospective analysis of the clinical data of 30 cases of ANFH in our hospital from December 2009 to May 2010(32 hips),all cases were treated with total hip arthroplasty.Acetabular side with biological prosthesis,femoral side with bone cement and biotype(each 16 hip).Scored and compared hip function of before and after surgery with the Harris hip score.Results All the patients were followed up for 3 to 12 months.The Harris hip score of 32 patients com pared with preoperative were significantly improved(P<0.05).Compared the bone cement group and the biotypes group,there were not significant difference in intra operative blood loss and length of stay(P > 0.05),but there were significant difference in operative time and postoperative complications(P<0.05).Conclusion The total hip replacement surgery is an effective means of treatment ANFH,the efficacy is similiar between cemented and biological prosthesis,and should be combined with the specific situation of the patient's to choose reasonable prosthesis.
目的 探讨锁骨钩钢板治疗Tossy Ⅲ型肩锁关节脱位的临床疗效.方法 采用锁骨钩钢板(clavicular hook plate,CHP)治疗Tossy Ⅲ型肩锁关节脱位患者,并按照是否进行术中缝合断裂的喙锁韧带将患者分为喙锁韧带修补组和未修补组,比较2组的临床疗效.结果 64例患者手术操作时间为40~70min,平均(55.5±8.6)min,术后第2天开始进行无负荷肩关节活动.所有患者术后随访1年,2组患者的肩关节功能评分比较差异无统计学意义(P＞0.05).本组64例患者术后1年取出钢板,钢板取出前、后肩关节功能评分和肩关节外展评分差异有统计学意义(P＜0.05).结论 锁骨钩钢板用于Tossy Ⅲ型肩锁关节脱位的治疗,疗效满意,值得在临床中推广.
