Y型锁定钢板置入治疗成人肱骨髁间骨折36例

背景：肱骨髁间骨折是一种复杂的关节内骨折，骨折端的显露及固定均比较困难。 目的：观察经尺骨鹰嘴截骨入路Y型解剖型锁定钢板治疗肱骨髁间骨折的效果。 方法：采用尺骨鹰嘴截骨入路，Y型解剖型锁定钢板治疗肱骨髁间骨折36例，男22例，女14例，年龄19~76岁，平均47岁，按AO/OTA分型：C1型8例，C2型15例，C3型13例。 结果与结论：32例获得随访，随访时间为10~26个月。用改良的Cassebaum评分标准评分，优15例，良13例，中3例，差1例，优良率89.6%。尺骨鹰嘴截骨入路切口无一例感染，骨折愈合时间为2.5~4.5个月，平均3.5个月。固定后钢板未出现松动现象。结果显示用尺骨鹰嘴截骨入路Y型解剖型锁定钢板治疗肱骨髁间骨折，显露范围广，固定牢靠，能有效防止骨折不愈合，可指导患者早期在CPM机上进行肘关节功能锻炼，肘关节功能恢复良好，是治疗肱骨髁间骨折的有效方法。

Y-type locking plate for intercondylar fractures of the adult hunmerus in 36 cases

BACKGROUND:Intercondylar fracture of the humerus is a kind of complex intra-articular fractures. Fracture exposure and fixation are difficult. OBJECTIVE:To explore the surgical effect of Y-type locking plate through the approach of olecranon osterotomy on intercondylar fracture of the adult humerus. METHODS:Thirty-six adult patients with intercondylar fractures of the hunmerus were treated with Y-type locking plate through the approach of olecranon osterotomy, including 22 males and 14 females, aged 19-76 years, averagely 47 year. According to the AO/OTA classificaiton, type C1 fracture was found in 8 cases, type C2 in 15, and type C3 in 13. RESULTS AND CONCLUSION:Thirty-two cases received a follow-up of 10-26 months. According to Cassebaum scale, the function of the elbow showed excellent in 15 cases, good in 13 cases, fair in 3 cases and poor in 1 case, and the excellent-good rate was 89.6%. No infection occurred. The mean time for fracture healing was 2.4 to 4.5 months, averagely 3.5 months. The technique of Y-type locking plate for intercondylar fracture of the adult humerus is effective against bone nonunion. Early rehabilitation for patients on the CPM machine is better for elbow joint function. It is an effective method for intercondylar fracture of the humerus.
