Abstract:
Objective To introduce the technique and efficacy of the treatment of avulsion fracture at tibial insertion of anterior cruciate ligament(ACL) in children through internal fixation by hollow cancellous bone screw under arthroscope.Methods December 2002 ～December 2007,internal fixation using percutaneous reduction by leverage was conducted in 68 children with avulsion fracture at tibial insertion of ACL in our hospital.In 68 children,there were 29 females and 39 males,aged 6～15 years(average age of 12 years),including 22 cases of typeⅡ(with limited knee extension)and 46 cases of type Ⅲ.The fracture was fixed by hollow titanium cancellous bone screw.Results Sixty eight cases were followed up for an average of 18 months(12～36 months).The muscle tension(mea sured by KT-2000) in injured side was recovered close to the uninjured side.Excellent reduction,solid inter nal fixation,complete healing,stable knee joint and negative Lachman and drawer tests were shown in this clinical setting.No swelling,pain and knee dysfunction were found.Impingement sign at intercondylar fossa disappeared.The patients were satisfied with their functional recovery.There was no abnormal angulation and shortness.Conclusion Treatment of avulsion fracture(type Ⅱ with limited knee extension or type Ⅲ) at tibial insertion of ACL by arthroscopic internal fixation with hollow titanium alloy cancellous bone screw could obtain accurate and reliable reduction,and avoide epiphysis injury with satisfactory functional recovery.
