Abstract

Objective To explore the anatomical basis and clinical application of a novel anterior median neurovascular approach for the treatment of coronoid process fractures of elbow joint. Methods After brachial plexus block combined with general anesthesia, patients with elbow coronoid fracture were assessed of damage degree of the collateral ligament. An incision is made along the transverse crease of the skin in front of the elbow and the inner side of the elbow. The medial collateral ligament and the posterior structures, the coronoid process of the ulna, the anterior joint capsule, and the anterior bundle of the medial collateral ligament were exposed through the space between the brachial artery and the median nerve in front of the elbow joint, The anterior joint capsule is longitudinally cut to expose the fracture site of the coronoid process, and then the medial collateral ligament, anterior joint capsule, and other structures were repaired under direct visualization for reduction and fixation. Elbow joint stability was evaluated by postoperative stress tests and the anterior and posterior drawer tests. Results The improved median nerve vascular approach could provide a clear surgical field of view for surgical procedure. By this approach, the fracture area exposed clearly, protected the median nerve and brachial artery, and achieved precise recovery of the fracture fragment. Postoperative functional exercises was favorable for function recovery of elbow joint. Conclusions The modified anterior median neurovascular approach has significant advantages in treating coronal process fractures of the elbow joint, which can improve fracture healing, and promote early functional recovery of patients.
