Cubitus valgus deformity resulting from nonunion of the lateral condyle of humerus may contribute to tardy ulnar nerve palsy. This causes the cubitus valgus nerve to take a longer course around the olecranon process, leading to excessive stretching of nerve. Repeated stretching causes interneural fibrosis and leads to nerve palsy. Anterior submuscular transfer affords good functional outcomes without addressing the nonunion of the lateral condyle of humerus.
