Arthroscopic Internal Fixation of Displaced Tibial EminenceFracture Using Cannulated Screw / 대한정형외과학회잡지

ABSTRACT

PURPOSE: This study examined the outcome of arthroscopic internal fixation for types II and III tibial eminence fractures in children using a cannulated screw. MATERIALS AND METHODS: A series of 10 cases of displaced fractures of tibial eminence of the tibia that were treated with an arthroscopic cannulated screw fixation from February, 1997 to October, 2005 were examined. Four patients had a type II and six patients had a type III tibial eminence fracture according to the Meyer and McKeever's classification. All the patients were reviewed radiographically and clinically for bone union, instability and the range of motion after an average follow-up of 22.4 months (range, 12 to 81 months). RESULTS: There were no cases of nonunion. The clinical examination showed that, all the patients with types II and III lesions had a negative Lachman test, and a full range of motion with the exception of one patient with a type III fracture. The average Lysholm functional score was 96.3 (mim 92.6-max 99.0) for all types II and III lesions. CONCLUSION: Arthroscopic internal fixation with a cannulated screw for types II and III avulsion fractures of the tibial eminence in children can provide a satisfactory outcome through firm fixation of the fragment and an early start of the range of motion.
