An arthroscopic technique for the reduction and fixation of pediatric tibial eminence fractures

目的介绍一种关节镜下儿童移位胫骨嵴撕脱骨折复位钢丝固定技术.方法根据Meyers and McKeever分型,12例儿童患者中Ⅱ型骨折4例,Ⅲ型骨折8例.在关节镜下骨折复位,用钢丝缝合固定.结果术后随访32个月(22～49个月),临床检查全部患者无伸直受限,Lachmann征轻度阳性2例,前抽屉试验阳性1例.X线检查全部骨折均骨性愈合,骨折无移位、无畸形愈合.结论该手术方法操作较简单,可重复性强,可达到胫骨嵴骨折的复位、固定和愈合.

Objective To introduce an arthroscopic technique for the reduction and fixation of pediatric tibial eminence fractures. Methods Twelve cases of type Ⅱ and type Ⅲ pediatric tibial eminence fractures, according to the classification of Meyers and McKeever, were treated with arthroscopic reduction and fixation with wire suture in this institution. All of them were followed up. The degree of bone healing and motion of the joints were evaluated. Results All of them got the full bone healing and the normal range of joint＇s motion during an average 32 months （22-49 months） followup. Two cases had slight positive Lachmann sign and the other one with positive anterior drawer test. Conclusions The arthroscopic technique is an easier manipulation, and deserves to be an ideal treatment for children with tibial eminence fractures.
