生物可吸收张力带治疗尺骨茎突骨折的评价

背景：选择合适的内固定材料是治疗骨折成败的重要因素，生物可吸收材料成为骨折治疗的研究热点。目的：探讨生物可吸收张力带的材料特点以及治疗尺骨茎突骨折的疗效。方法：病例分析选取2009年11月至2012年2月采用生物可吸收张力带结合克氏针治疗尺骨茎突骨折患者36例，男21例，女15例；年龄21—73岁，平均年龄35．7岁，观察患者治疗后骨折愈合情况以及腕关节活动功能。并深入了解生物可吸收张力带材料种类和特性以及内固定的强度，比较生物可吸收张力带与金属张力带内固定的优缺点。结果与结论：生物可吸收张力带治疗尺骨茎突的36例患者，随访2个月-2．5年，平均随访8．5个月，X射线检查结果均提示骨折愈合，采用AO的Gartland．Werley方法对腕关节活动功能进行评估，优24例，良10例，中1例，差1例，优良率为94％。说明生物可吸收张力带有利于关节功能的恢复，在骨折愈合过程中可以逐渐转移应力，保持骨折部位的强度，材料的可降解性使患者避免了二次手术的痛苦。可见生物可吸收张力带结合克氏针治疗尺骨茎突骨折能取得较好的疗效。

Bioabsorbable tension band for the treatment of ulnar styloid fracture

BACKGROUND： Selection of the appropriate internal fixation materials is an important factor in the success of fracture treatment. Bioabsorbable materials will become the hotspot fracture research. OBJECTIVE： To investigate the material characteristics of bioabsorbable tension band and the effect onthe treatment of ulnar styloid fracture. METHODS： Thirty-six patients with ulnar styloid fracture that treated with bioabsorbable tension band and Kirschner from November 2009 to February 2012 were selected for cases analysis, including 21 male patients and 15 female patients; the age of the patients was 21-73 years, average 35.7 years. The bone fracture healing and wrist joint function was observe after treatment, and the material types, characteristics and fixation strength were in-depth studied. The pros and cons of bioabsorbable tension band and metal tension band were compared RESUTLS AND CONCLUSION： All the 36 ulnar styloid fracture patients were treated with bioabsorbable tension band and followed-up for 2 months to 2.5 years, average 8.5 years. X-ray examination showed the fractures were healed. The wrist joint function was evaluated with Gartland-Werley, and the results showed 24 cases of excellent 10 cases of good, one case of average and one case of poor, and the excellent and good rate was 94%. The results indicate that bioabsorbable tension band is favorable for the recovery of joint function, and can gradually transfer the strain during fracture healing and maintain the strength on the fracture site. The degradability of the material can help to avoid the pain of secondary surgery. From the results we can indicate that bioabsorbable tension band and Kirschner wire is the ideal method for the treatment of ulnar styloid fracture.
