Axillary Artery Injury Secondary to Inferior Shoulder Dislocation

Axillary Artery Transection and Brachial Plexus Injury After Open Inferior Glenohumeral Dislocation: A Case Report

CASE

A judo athlete presented with an open inferior shoulder dislocation that occurred during competition. Examination revealed a transection of the axillary artery and neuropraxia of the posterior cord. Neuropraxia was resolved within 2 weeks. The axillary artery was repaired with a femoral vein graft. He regained full strength, range of motion, and function at 8 months.

CONCLUSION

Inferior glenohumeral dislocations are rare, and their management can be complicated by vascular and neurological injuries. We emphasize the importance of examination, diagnosis, and treatment of neurovascular pathologies to avoid catastrophic outcomes.

Brachial plexus injury secondary to pseudoaneurysm of axillary artery after glenohumeral dislocation: case report

Lesions of the axillary artery and consequent compression of the brachial plexus are extremely rare in patients with glenohumeral dislocation and may have greatly varying clinical manifestations. This joint is one of the most affected by dislocation in the human body, accounting for approximately 45% of cases. Less than 1% of patients with shoulder dislocation have vascular complications; however, when there is damage in the axillary artery, the incidence of associated brachial plexus injury is 27% to 44%. The authors report on a case of brachial plexus compression by an axillary artery pseudoaneurysm after a glenohumeral dislocation, aiming to highlight the existence of this association, in order to make an early diagnosis and avoid serious complications, such as neurologic injury.

Proximal humerus fractures with associated axillary artery injury

Proximal humerus fractures have rarely been associated with injuries to the axillary artery. Most of the fractures described have been Neer 2-part surgical neck fractures with medialization of the shaft fragment and resultant laceration or thrombosis of the axillary artery. No intraoperative deaths have been reported. We present a series of 3 proximal humerus fractures, 2 of which are Neer 3- to 4-part anterior fracture dislocations, and associated axillary artery injury. There were 2 mortalities, 1 intraoperative. After a thorough review of the English literature, we identified an additional 11 cases of axillary artery injury associated with proximal humerus fracture. The purpose of this study was to heighten the clinical suspicion of this vascular injury in patients with proximal humerus fracture dislocations and surgical neck fractures with shaft medialization, as well as to review pathogenesis and guide management decisions.

[Axillary artery pseudo-aneurysm secondary to shoulder dislocation in children]

Axillary artery injury following anterior dislocation of the shoulder in children is a rare complication often considered as iatrogenic. We report the case of a pseudo-aneurysm of the axillary artery in a 5-year-old boy that appeared four months after a shoulder dislocation that was reduced in an ambulatory setting. Although this is an uncommon vascular complication, we emphasize the need for short-term and long-term follow-up in these children to avoid missing a pseudo-aneurysm of the axillary artery.

Humerus axial traction with acromial fixation reduction maneuver for anterior shoulder dislocation

BACKGROUND

Many techniques have been described for the reduction of anterior glenohumeral dislocation, but each of the techniques has its disadvantages. A new shoulder reduction technique is needed to overcome these disadvantages.

DESCRIPTION

An alternate technique of humerus axial traction with acromial fixation is presented. The technical description of this procedure focuses on the pre-reduction and post-reduction process. The use of acromial countertraction, the choice of the most loosely packed position of the shoulder joint, and the operator's ability to reduce muscle spasm are the main principles discussed.

CONCLUSION

This modified technique increases the possibilities for the reduction of shoulder dislocation in different clinical situations.
