Antegrade Reduction and Fixation of Coronoid Fractures: A New Arthroscopic Technique

摘要

The coronoid process (CP) is important for stabilizing the elbow joint. The elbow’s joint fracture is considered the most common factor in several cases of complex elbow dislocations. The surgical indications for recommending the CP in fractures are prolonged instabilities of the elbow. The open fixation of the CP is a demanding procedure, owing to many complications after the surgeries. Arthroscopic reduction and internal fixation have been proposed to overcome the limitations of open approaches. The aim of our study is to describe, step by step, a new surgical procedure for arthroscopically assisted fracture reduction and insertion of an antegrade guidewire for internal fixation of coronoid fractures. To perform this surgery, the knowledge of the portals in elbow arthroscopy is essential. The final stabilization is achieved by accurate positioning of the Kirschner-wire under arthroscopic control and stabilizing by the cannulated screw. The proposed technique is a safe and appealing procedure in the treatment of coronoid fractures.
