Posterior dislocation of the shoulder associated with fracture of the humeral anatomical neck with 11-year follow-up after early open reduction and internal fixation.

BACKGROUND

. The combination of posterior dislocation and fracture of the anatomical neck represents an extremely rare injury.

METHODS

. A patient with posterior dislocation of the shoulder and ipsilateral fracture of the humeral anatomical neck was treated with open reduction and internal fixation with two Kirschner wires. He was followed up for 11 years.

RESULTS

. The functional results were excellent, and X-ray and MRI investigations revealed the absence of avascular necrosis of the humeral head.

CONCLUSION

. Early and accurate open reduction with minimal osteosynthesis resulted in excellent function of the injured shoulder without avascular necrosis.
