可吸收和金属张力带治疗尺骨鹰嘴骨折的对比研究

Biodegradable Tension Band and Metallic Tension Band for Fractures of Ulnar Olecranon

【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 3 6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～ 3 9个月 ,平均 2 4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。

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.
