自制尖齿开口卡压钢板治疗撕脱性骨折

目的　探讨自制尖齿开口卡压钢板治疗撕脱性骨折的特点和治疗效果。 方法　2012年1月～2015年2月,应用自制尖齿开口卡压钢板治疗撕脱性骨折16例,男性10例，女性6例。年龄最小20岁，最大63岁，平均43.6岁。其中，膝关节后交叉韧带胫骨止点撕脱性骨折8例，外踝撕脱性骨折2例，肱骨内上髁撕脱性骨折3例，肱骨大结节撕脱性骨折1例,尺骨鹰嘴撕脱性骨折2例。均为新鲜骨折，骨折分型（参照Meyer方法）：I型1例，Ⅱ型6例，Ⅲ型9例。术后均早期康复锻炼。分别按Lysholm膝关节评分、Kaikkonen踝关节损伤功能评分和DASH上肢功能调查表，评价各部位患肢功能恢复情况。 结果　术后切口均I期愈合，无血管神经损伤。16例患者均获随访，随访12～24个月，平均18.1个月。所有骨折均愈合, 愈合时间2～3个月，平均2.5个月,未见骨折移位和内固定松动。末次随访，患肢临近关节功能恢复优12例、良4例（优良率100%），无关节不稳和其它不良并发症发生。 结论　自制尖齿开口卡压钢板治疗撕脱性骨折方法简便、适应证广泛、固定可靠、效果良好。

Self-made sharp opening teeth entrapment plate for treatment of avulsion fractures

Objective　To investigate the characteristics and therapeutic efficacy of self-made sharp opening teeth entrapment plate for treatment of avulsion fractures.　Methods　Sixteen cases with avulsion fractures were treated with self-made sharp opening teeth entrapment plate between January 2012 and February 2015. There were 10 males and 6 females, with an age ranging from 20 to 63 years old, averaging 43.6 years old. Among all the cases, there were posterior cruciate ligament tibial avulsion fractures in 8 cases, lateral malleolus avulsion fractures in 2 cases, medial humeral epicondyle avulsion fractures in 3 cases,greater tuberosity of humerus avulsio fractures in 1 cases and olecranon avulsion fractures in 2 cases. All were fresh fractures, and the fracture type（according to Meyer method）: type I in 1 cases, type II in 6 cases and type III in 9 cases. Early postoperative rehabilitation was taken. The limb functionary recovery was evaluated according to the Lysholm knee score, Kaikkonen ankle injury scores and DASH upper limb function evaluation questionnaire, respectively.　Result　The incision healed by first intention, without vascular and nerve injuries. All were followed up, the follow-up time was 12~24 months , with an average 18.1 months. All fractures healed, and the healing time was 2~3 months,with an average 2.5 months. No redisplacement of fracture and loosening of internal fixation occured. At the last follow-up, the limb functionary recovery was excellent in 12 cases, good in 4 cases (the excellent and good rate was 100%). no instability of joint and other complications was noted. 　Conclusion　Self-made sharp opening teeth entrapment plate for treatment of avulsion fractures is simple, widely indicated, and has reliable fixation and good effectiveness.
