生物可吸收张力带治疗尺骨鹰嘴骨折9例

Treatment of olecranon fracture with biodegradable tension band in 9 cases

背景:目前尺骨鹰嘴骨折治疗的方法最常采用的是钢板螺钉或克氏针张力带内固定,都需要二次手术取出内固定物。目的:回顾性分析采用可吸收螺钉+可吸收缝线形成生物可吸收张力带治疗尺骨鹰嘴骨折的效果。方法:2006-07/2009-04同济大学附属东方医院收治的尺骨鹰嘴骨折患者9例,均采用可吸收螺钉+可吸收缝线形成生物可吸收张力带治疗,术后辅以石膏外固定3周后行肘关节功能锻炼。随访12个月,根据X射线片和Mayo肘关节功能评分评定疗效。结果与结论:9例患者术后影像学检查均愈合良好,骨折线模糊;Mayo肘关节功能评分优8例,良1例,未发生尺神经卡压症状;均未发生骨折或骨折端再移位现象。生物可吸收张力带治疗尺骨鹰嘴骨折可为患者早期功能锻炼提供足够的强度,具有固定效果好、无需二期手术取出内固定物的优点,是治疗尺骨鹰嘴骨折较理想的方法之一。

BACKGROUND：Internal fixations with plate and screw or K-wire tension band are widely used in treating olecranon fracture;however,the internal fixations need to remove by a second surgery.OBJECTIVE：To retrospective analyze the therapeutic effect of treating olecranon fracture using biodegradable tension band.METHODS：Nine olecranon fracture patients received at the Shanghai East Hospital of Tongji University from July 2006 to April 2009 were selected.All patients were treated by biodegradable tension band fixation which comprises absorbable screw and absorbable suture.Elbow joint functional exercises were performed at 3 weeks after plaster external fixation.The patients were followed up for 12 months,and the therapeutic effect was measured by X-ray films and Mayo score of elbow joint function.RESULTS AND CONCLUSION：Imaging examination showed that the fracture healing well in all cases,and the fracture line was blurred.No ulnar nerve compression,fracture,or fracture displacement could be seen.Biodegradable tension band fixation can provide adequate intensity for functional exercises,which has the virtue of effective fixation without a second surgery to remove fixation.It is believed to be a good method for the treatment of olecranon fractures.
