摘要 目的 研究生物可吸收张力带(Biofix棒和Biopoly人工韧带)与金属张力带(克氏针和钢丝)治疗尺骨鹰嘴骨折的疗效。方法 采用两种张力带治疗36例尺骨鹰嘴骨折。其中，可吸收带组19例；金属张力带组17例。随访时间8～39个月，平均24个月，根据术后X线片和关节功能恢复情况评定疗效。结果 平均骨折愈合时间为7周。可吸收张力带组：优16例，良3例；金属张力带组：优14例，良2例，差1例。两种治疗方法临床效果无统计学差异。结论 生物可吸收张力带象金属张力带一样是治疗尺骨鹰嘴骨折较理想的有效方法之一，并具有无需二期手术取出内固定的优点。

Abstract Objective To compare the efficacy of treatment for fractures of ulnar olecranon fixed by biodegradable tension band (BTB)with Biofix rods/Biopoly ligaments and metallic tension band (MTB)with Kirschner needle and metallic cerclage wire.Methods Thirty-six patients with fractures of ulnar olecranon (19 fixed by BTB and 17 by MTB) were evaluated by radiography and recovery of joint function.The follow-up time lasted 8～39 months (24 months on the average).Results The fractures cured after a mean time of 7 weeks.In BTB group,good clinical results were obtained in 16 patients,whereas those in 3 patients were fairly well.In MTB group,the corresponding fiqures were 14 and 2,but poor result was found in one patient.There was no statistically significant difference between these two methods.Conclusion Biodegradable tension band is believed to be a good simple method for the treatment of ulnar Olecranon fractures needing not a second-stage operation for removal of implants.

尺骨鹰嘴骨折通常由间接或直接暴力引起，往往需手术治疗，内固定的方法很多，其中张力带固定是一种良好的方法，缺点是需二期取出内固定物。作者等采用生物聚酯人工韧带和可吸收棒，形成可吸收张力带治疗尺骨鹰嘴或髌骨骨折，取得成功［1，2］。本文比较可吸收张力带与金属张力带治疗尺骨鹰嘴骨折的疗效，现报道如下。
1 材料和方法
1.1 生物聚酯人工韧带 法国ARTICAL公司生产，品名 polyester ligament。编织成不同的形状供不同的用途。本文选用多功能加固韧带(LCCLACT)：长度50 mm，直径1.5 mm。其抗拉强度＞650 N，体[1] [2] 下一页
