We choose conservative treatment for type I fractures unless the bone fragment affected movement of the elbow joint, in which case we chose operative treatment so that elbow stability was not affected. Type II and type III fractures with elbow instability were reduced by internal fixation and the ligament repaired or reconstructed. In type IV cases, bone reconstruction was necessary to recover elbow stability. Proper post-operative rehabilitation can decrease the occurrence of traumatic osteoarthritis.

The present study has demonstrated a new approach for adequately exposing the distal humeral articular surface during surgery for an intercondylar humerus fracture. With this modified approach, osteotomy of the olecranon and the separation or transection of the main part of the triceps brachial tendon from the olecranon are not necessarily required. Therefore, we suggest that this novel approach could be applied as the primary surgical approach in intercondylar humerus fracture surgeries if the surgeons are familiar with the regional features of distal tendon of the triceps brachii and anconeus.
