纸夹板内收位固定与石膏外展位固定治疗Bennett骨折的随机对照试验

目的：研究比较纸夹板内收位固定与石膏外展位固定治疗Bennett骨折的疗效差异。方法：选择2005年10月至2007年4月门诊就诊的70例Bennett骨折患者，按区组随机的方法分为试验组35例（纸夹板内收位固定）和对照组35例（石膏外展位固定）进行治疗。骨折达到临床愈合拆除固定后，对患者进行为期6个月的随访观察。分别于骨折后6、8、12、16、20及24周按改良的Gabriele评分系统对其患手功能进行量化评分比较。结果：两组的优良率在8、12、16及20周时比较试验组优于对照组，差异有统计学意义（P〈0．05）；6周和24周时比较差异无统计学意义（P〉0．05）。两组在功能评分方面，8、12、16、20及24周时比较试验组高于对照组，差异有统计学意义（P〈0．05）；6周时积分差异无统计学意义（P〉0．05）。结论：在Bennett骨折的治疗中，纸夹板内收位固定与石膏外展位固定相比能明显加快患手功能的恢复，而且固定轻便、舒适，患者易于接受，可以作为一种有效的固定方法在临床推广。

Comparison of the therapeutical effectiveness between paper splint adduction fixation and plaster abduction fixation in Bennett fracture

Objective: To study and compare the difference on the therapeutical effectiveness between paper splint adduction fixation and plaster abduction fixation in Bennett fracture. Methods: In the study,seventy outpatient were selected from October 2005 to April 2007,and devided into two groups randomly involving experiment group(35 cases with paper splint add- uction fixation) and control group(35 cases with plaster abduction fixation). After the fracture clinical healed and removed fixation,the patients had been followed up 6 months. At the 6th,8th,12th,16th,20th,24th week after fracture,the fracture hand had been scored and compared according to Gabriele's score system. Results: At the 8th,12th,16th and 20th week,the excellent rate of experiment group was higher than control group,there was significant difference(P<0.05);At 6th week and 24th week the- re was no significant difference(P>0.05). At 8th,12th,16th,20th and 24th week,the functional score of experiment group was h- igher than control group,there was significant difference(P<0.05);At 6th week there was no significant difference(P>0.05). Conclusion: The paper splint adduction fixation could promote recovery of the hand function in Bennett fracture. In addition,the paper splint adduction fixation is comfortable to recipient. It could be spreaded in clinic as a effective fixation method.
