title: Osteochondritis dissecans of the humeral trochlea with cubitus varus deformity. A case report.
abstract: Osteochondritis dissecans of the elbow primarily involves the capitellum. We report a rare case of osteochondritis dissecans involving the humeral trochlea in a 19-year-old male with a post-traumatic cubitus varus deformity. Biomechanics suggested that the varus malalignment caused repetitive axial force across the medial elbow, which led to microtrauma to the trochlea during the patient's daily work. In adolescents, post-traumatic cubitus varus can gradually progress to subsequent osteochondritis dissecans of the humeral trochlea.
