Osteosynthesis for nonunion of the lateral humeral condyle.

The treatment of established nonunion of the lateral humeral condyle is controversial. Twenty patients who had osteosynthesis of the nonunion were evaluated to clarify the changes in range of motion and the factors influencing those changes. The average age of the patients at surgery was 13.

Long-standing nonunion of fractures of the lateral humeral condyle.

Background: Patients with nonunion of a fracture of the lateral humeral condyle often have pain, instability, or progressive cubitus valgus deformity with tardy ulnar nerve palsy. However, some patients have minimal or no symptoms or disabilities. We evaluated patients with long-standing established nonunion of the lateral humeral condyle to correlate the clinical long-term outcome of this condition with the original fracture type.
