In this article, we report the case of an active, thirty years old, male patient with isolated, displaced fracture of the coracoid process, associated with a blunt injury to the shoulder, during a motor vehicle accident. We describe the incidence, mechanism of injury, and surgical treatment. Although rare, a high index of suspicion, special radiographic views, can detect an isolated coracoid process. Knowledge of the associated injuries will help the clinician to order further imaging and treat them accordingly. We recommend that a displaced, isolated fracture of the coracoid be treated with open reduction and osteosynthesis, to achieve early use of the extremity, good radiological union and clinical function.展开更多

Isolated fractures of this prominence are rare conditions. Herein we present two isolated coracoid fractures after a motorcycle accident and a fall onto the shoulder respectively. Conservative treatment with sling and passive-active shoulder exercises is accepted approach in these fractures. We also prefer conservative treatment at our cases and both of them have good results.展开更多

Because of its deep anatomic location, they hardly sustain any direct traumatic force. Most of the time, they get fractured by indirect force by the muscles and ligaments attached to them. They are usually associated with fracture of the acromion process of Scapula, acromio-clavicular dislocation and proximal humerus fracture or dislocation of the shoulder joint. They may be missed because more attention is drawn by the obvious injuries. We report two cases of coracoid process fracture, one is associated with fracture dislocation of the shoulder and the other with acromion process fracture.展开更多

Methods: We modified Dewar’s surgical method as follows: (1) Two small incisions, a transversal incision on the acromioclavicular joint and a longitudinal incision on the coracoid, were made instead of a conventional large arc incision from the acromion to coracoid. (2) The foreign body in the acromioclavicular joint was cleared out. The chondral surface at the lateral segment of clavicle was resected to form a pseudarthrosis and meanwhile the residual joint capsule and ligaments were repaired. (3) The coracoid was moved to the anteroinferior edge of the clavicle instead of the anterior margin and (4) the coracoid was moved to the lateral border of the clavicle instead of the superior border of the coracoclavicular ligament. Results: The follow up duration in 30 patients of the series was from 6 to 72 months (mean 41 months). Functional assessment was carried out by the criteria delineated previously by Karkson, in which Grade A was in 24 cases, Grade B in 4cases, and C in 2. Conclusions: This modified technique, having less postoperative complications and less injuries to tissues and according well with the requirement of biomechanics, can achieve a stable reduction of acromioclavicular joint with a good functional and cosmetic result and therefore is preferable to use clinically on a large scale.展开更多
