Acute and chronic coronoid reconstruction using the olecranon Tip

Abstract

Post-traumatic coronoid deficiency in the elbow can lead to chronic pain, instability and arthritis. A variety of osteochondral grafts have been used to reconstruct the coronoid, and restore elbow stability. The radial head and iliac crest grafts are the most common in the literature but have limitations. The olecranon tip is a promising alternative, with both cadaveric and computer models demonstrating superior congruency, without compromising elbow stability or disrupting the extensor mechanism. We present a small, case series demonstrating the technique for contralateral and ipsilateral grafts in both the acute and chronic setting.
