Purpose: Although nonunion of the lateral humeral condyle is a rare complication in children, it can result in a number of complications, and treatment is controversial. Our study shows the results of using osteosynthesis in patients whose lateral humeral condyle was not united.
Materials and Methods: We studies 16 patients (M : F=13 : 3; Age: 11.8±5.2 years) who were diagnosed with nonunion of the lateral humeral condyle and who underwent osteosynthesis. The mean period of nonunion was 56.2 months (5-132 months). Outcome measures were range of movement, bone union, functional score, and carrying angle and were assessed both before and after surgery.
Results: Bones of all patients were united within 3 months of the operation; there were no complications. After surgery, a decreased range of movement was observed for 3 of 16 patients. However, the functional index for all patients was improved. In other words, the range of movement could be reduced while the functional index was improved so that the deformity would be lessened.
Conclusion: Osteosynthesis was successful in repairing the nonunion of the humeral lateral condyle. Therefore, osteosynthesis is suggested for patients who have had no treatment for nonunion of lateral humeral condyle for a long time.
