title: Arthroscopic treatment of comminuted distal clavicle fractures (latarjet fractures) using 2 double-button devices.
abstract: Complex distal clavicle fractures associated with a rupture of the coracoclavicular ligaments (Latarjet fractures) can result in delayed union or nonunion. There is no standard treatment for a clavicle fracture. This report introduces an arthroscopic technique for treating distal clavicle fractures associated with ruptured coracoclavicular ligament using 2 double-button devices. By use of posterior and anterior standard arthroscopic portals, the base of the coracoid process is exposed through the rotator interval. A 4-mm hole is drilled through the clavicle and the coracoid process with a specific ancillary drill guide. The first button is pushed through both holes down the coracoid process. The device is tightened, and the second button is fixed on top of the clavicle, allowing reduction and fixation of the proximal part of the fracture. Then, the undersurface of the lateral clavicle is dissected through standard posterior and lateral subacromial approaches. The inferior clavicle fragment is reduced and fixed to the clavicle body by a double button fixed down and at the top of the clavicle. With this technique, the arthroscopic treatment of distal clavicle fracture has been extended to comminuted fractures.
