The authors acknowledge that no method of coracoclavicular ligament
reconstruction is without failure, despite being concerned by this mechanism of failure.

(1-4) These injuries have a wide range of severity, from sprains of the acromioclavicular and coracoclavicular ligaments
to complete dislocation of the AC joint.
The purpose of our study was to compare outcome between clavicular hook plate and coracoclavicular ligament
reconstruction using autograft in chronic Grade III injury.

(29) This article will discuss several of the common methods of surgical treatment of AC joint injury such as hook plate stabilization and numerous variations of the modified Weaver-Dunn technique but will focus on the more current techniques of anatomic coracoclavicular ligament
augmentation or reconstruction.
Injuries involving the distal clavicle in children are classically "pseudodislocations" of the AC joint in which the joint and the coracoclavicular ligaments
are usually intact, and fracture involves the lateral physis of the clavicle with displacement of the bone through a split in the periosteal sleeve.
* Type I: Fracture proximal to the coracoclavicular ligament
Our operative indications for fixation of coracoid fractures include displaced base fractures (i.e., Ogawa and colleagues, (1) type I; Eyres and coworkers, (4) types III to V), and those with associated type III or greater acromioclavicular dislocation, coracoclavicular ligament
disruption, distal clavicle fracture, and significant intraarticular involvement of the glenoid fossa.
Surgical treatment for distal clavicle fracture associated with coracoclavicular ligament
rupture using a cannulated screw fixation technique.
The shoulder girdle effectively hangs from the clavicle by the coracoclavicular ligament
. This has been described as being similar to a "sign post," whose arm, the clavicle, is dynamically stabilized by the trapezius.
Coracoid fractures with ipsilateral acromioclavicular joint (ACJ) dislocation usually occur at the base or neck of the coracoid process (CP), with an intact coracoclavicular ligament
(CCL) attached to the fracture fragment [1-4].
* Anatomically, the acromioclavicular and coracoclavicular ligament
attach the clavicle to the scapula laterally.
A curved oscillating saw was then utilized to cut the base of the coracoid, taking care not to damage the coracoclavicular ligaments
. A vertical capsular incision was performed at the level of the glenohumeral joint followed by removal of the capsule at this level and medial along the anterior neck of the scapula.
