Surgical treatment of Segond fracture combined with anterior cruciate ligament injury / 中华创伤杂志

ABSTRACT

ObjectiveTo investigate the injury mechanism,clinical characteristics and surgical treatments of Segond fracture combined with anterior cruciate ligament (ACL) injury.MethodsNine patients suffering from Segond fracture combined with ACL injury were treated between January 2008 and December 2010.All the patients revealed ACL and medial collateral ligament (MCL) breakage under arthroscopy.Furthermore,one patient was associated with lateral collateral ligament (LCL) breakage and medial meniscus injury,four with medial meniscus tear and two with lateral meniscus tear.All the patients underwent arthroscopic tendon allotransplantation,ACL reconstruction and MCL repair.Besides,synchronous LCL reconstruction was performed in one patient,meniscus suture in three and meniscus plasty in four.Six patients with large Segond fracture fragments were fixed with two hollow lag crews and three with relatively small fracture fragments fixed with one hollow lag crew.ResultsThe mean followup period was 12 months,which showed average postoperative Lysholm score of 59 points and satisfactory clinical outcome.ConclusionsSegond fracture is often combined with ACL injury and is predictive for ACL injury.In ACL reconstruction,large Segond fracture blocks should be reduced and fixed and the combined injuries also should be treated in the same period.
