A modified Kocher incision is used to approach the lateral elbow. Skin flaps are then elevated and the anterior capsule exposed by elevating the brachioradialis and extensor carpi radialis longus off the anterior supracondylar ridge. Further medial exposure is achieved by elevating the brachialis anteriorly.
