Given persistent pain, limitations in activities of daily living, and radiographic evidence of ipsilateral distal clavicle and coracoid base nonunions with disruption of the
coracoclavicular interval, the patient was indicated for operative intervention.
With higher energy injuries, there may also be damage to soft tissue surrounding structures such as the
coracoclavicular ligaments, acromioclavicular joint capsule, and underlying neurovascular structures.
No repair of
coracoclavicular ligament was done in one case reconstruction plate applied along with k-wire.
Laterally, the clavicle attaches to the scapula via the
coracoclavicular ligaments and acromioclavicular ligaments.
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].
* Type I: Fracture proximal to the
coracoclavicular ligament.
(13,17) In type I fractures, the
coracoclavicular ligaments are intact.
(8.) Cho B P and Kang H S.; Articular facets of the
coracoclavicular joints in Koreans.
The acromioclavicular joint (AC) is a diarthrodial joint, stabilized by the
coracoclavicular ligaments (conoid and trapezoid), the superior and inferior AC ligaments, and the AC capsule (Fig.
Coracoclavicular reconstruction is generally not required as the ligaments are intact and attached to the distal clavicle.
From a total of 30 diagnosed patients, 16 were identified as receiving nonoperative treatment and 14 open reduction and
coracoclavicular stabilization.
* Anatomically, the acromioclavicular and
coracoclavicular ligament attach the clavicle to the scapula laterally.
