1/9. Atraumatic floating clavicle and total claviculectomy.We describe a patient with a floating clavicle of atraumatic origin treated by total claviculectomy. Clavicular function and anatomy are summarized relative to complete excision. Other treatment options for panclavicular instability are also discussed.- - - - - - - - - - ranking = 1keywords = clavicle (Clic here for more details about this article) |
2/9. Radiographic findings of spontaneous subluxation of the sternoclavicular joint.Eight middle-aged women with spontaneous atraumatic subluxation of the sternoclavicular joint were evaluated with radiography and computed tomography. All patients were employed in occupations involving moderate to heavy physical labour, and no patients could recall a specific traumatic incident associated with onset of symptoms. In seven of the eight patients, the displacement of the medial clavicle was in a cranial direction; in four of the eight patients, there was an associated anterior subluxation, and in one patient, the subluxation was purely anterior. All five patients with an anterior component to the sternoclavicular subluxation had associated condensing osteitis of the clavicle. The sclerosis of the medial clavicle is possibly the result of chronic abrasion on the sternum and first costal cartilage in association with normal respiration and with upper extremity motion.- - - - - - - - - - ranking = 0.6keywords = clavicle (Clic here for more details about this article) |
3/9. brachial plexus injury with erect dislocation of the shoulder.Luxatio erecta, or inferior dislocation of the glenohumeral joint, is an extremely uncommon variety of shoulder dislocation. Several types of neurovascular injuries may be associated with luxatio erecta. Concomitant fracture of the coracoid, clavicle, acromion, greater tuberosity, and humeral head may also be noted. A case of luxatio erecta associated with a fracture of the greater tuberosity and transient mixed brachial plexus injuries is presented.- - - - - - - - - - ranking = 0.2keywords = clavicle (Clic here for more details about this article) |
4/9. Luxatio erecta humeri. A case report.Luxatio erecta humeri is a rare type of glenohumeral dislocation. The pathomechanics of this injury involve either direct axial loading on a fully abducted extremity or leverage of the humeral head across the acromion by a hyperabduction force. The clinical presentation of this type of shoulder dislocation is unique, with the affected extremity held rigidly above the head in abduction. Reduction is accomplished by a form of traction-countertraction under intravenous sedation and analgesia. A variety of neurologic and vascular injuries may be associated with luxatio erecta humeri, involving the brachial plexus and axillary artery, respectively. Concomitant fracture of the acromion, clavicle, coracoid, greater tuberosity, and humeral head may also be seen. A computed tomography scan of the case reviewed here revealed a large humeral head defect oriented perpendicular to the classic Hill-Sachs lesion. Luxatio erecta humeri is associated with significant late morbidity, including recurrent dislocation, instability, and adhesive capsulitis.- - - - - - - - - - ranking = 0.2keywords = clavicle (Clic here for more details about this article) |
5/9. Treatment of avulsed clavicle and recurrent subluxations of the ipsilateral shoulder by dynamic fixation.A new operative approach is presented for treatment of fractured distal end of clavicle associated with recurrent anterior shoulder subluxations. One case is presented in which open reduction of the fractured clavicle and stabilizing the anterior shoulder joint were accomplished by transfer of the coracoid process with its attached muscles under the subcapularis muscle onto the clavicle. The operation was followed by complete reduction of the fracture and a stable shoulder joint.- - - - - - - - - - ranking = 1.4keywords = clavicle (Clic here for more details about this article) |
6/9. Unusual dislocations of the shoulder.Erect (luxatio erecta) and superior glenohumeral dislocations are extremely uncommon. In luxatio erecta, the humeral head is subglenoid or subcoracoid just as in the more common anterior dislocation, but the shaft of the humerus is parallel to the spine of the scapula, not parallel to the chest wall as seen in the anterior type. Superior dislocations have the humeral head overlying the acromion or the clavicle on the anteroposterior radiograph. Radiographic findings in seven cases are presented and some of the associated complications are discussed.- - - - - - - - - - ranking = 0.2keywords = clavicle (Clic here for more details about this article) |
7/9. Coracoid fracture as a complication of surgical treatment by coracoclavicular tape fixation. A case report.In a 22-year-old man surgically treated for acromioclavicular dislocation, coracoid fracture was caused by bone failure at the Mersaline loop. The addition of bony erosion between the two drill holes in the clavicle caused the tape to loosen and the deformity to recur. Postoperative infection may also have played a role in causing the coracoid fracture. When tape is used, it should be passed around the clavicle, not through it. If the deformity recurs, coracoid fracture should be suspected.- - - - - - - - - - ranking = 0.4keywords = clavicle (Clic here for more details about this article) |
8/9. Compression brachial plexopathy caused by chronic posterior dislocation of the sternoclavicular joint.thoracic outlet syndrome developed in a patient due to chronic posterior dislocation of the sternoclavicular joint, following an all-terrain vehicle accident. decompression of the thoracic outlet was accomplished by surgical reduction of the clavicle, excision of the medial clavicle and reconstruction of the costoclavicular ligament. The patient's symptomatology was relieved by the surgical procedure performed.- - - - - - - - - - ranking = 0.4keywords = clavicle (Clic here for more details about this article) |
9/9. axillary artery injuries after proximal fracture of the humerus.Although axillary artery injury occurs frequently with dislocations of the shoulder and fractures of the clavicle, it is rarely associated with fractures of the proximal humerus. If the axillary artery is damaged, prompt recognition and treatment are necessary to salvage the involved extremity.- - - - - - - - - - ranking = 0.2keywords = clavicle (Clic here for more details about this article) |
