A study to assess the effect of articular congruency and displacement in treatment of fracture of lateral condyle of humerus in children

Abstract

Background: Lateral condyle fractures of the distal humerus are the second most common fractures at the elbow in the paediatric population which if not properly treated leads to non-union deformity and other complications. Operative intervention with closed reduction and percutaneous pinning or open reduction internal fixation are indicated for a malaligned articular surface and/or an unstable fracture. Intraoperative arthrograms helps in doubtful congruency of joint surface and in assessing joint reduction. We present our results of treatment of fracture lateral condyle humerus in 24 patients and effect of the fracture displacement and congruency on functional and clinical outcome. Aim: The aim of our study was to assess functional and clinical results of fracture lateral condyle of humerus in children based on articular congruency. Materials and Methods: It was a retrospective study of total 24 patient with isolated fracture of lateral condyle of humerus. Open fracture and other co morbidities cases were excluded. Functional and clinical outcome according to hardware criteria was evaluated. Results: There were 24 cases in study with average age of 7.54 years. There were 19 male and 05 female. According to Jacob classification 06 were type I, 06 were type II and 12 were type III. Arthrography helped in decision making in doubtful cases of joint congruency. 100% excellent results achieved in type I and type II fractures whereas in 85% cases of type III fractures achieved excellent to good results. Increase operative time is associated with spur formation. Conclusion: Appropriate plan of treatment decided on articular congruency and displacement with the help of arthrography gives excellent results in fracture lateral condyle of humerus.
