Open Reduction and Internal Fixation of Posterior Fracture Dislocation of the Shoulder Made Easy!

Posteriorly dislocated humeral head fracture has a great implication, as it is associated with high risk of avascular necrosis, limited access through the deltopectoral approach, and posterior approach to the posteriorly dislocated humeral fracture increases the risk to the remaining blood supply.

Posteriorly dislocated humeral fracture is approached through deltopectoral approach. Schanz pin is inserted into the humeral head to achieve purchase in the humeral head. Applying laterally directed force the humeral head is disengaged from the lateral margin of glenoid. A rotatory force then repositions the humeral head into a congruous position. Open reduction internal fixation is then carried out in a standard fashion.

Retrieving the humeral head from the posteriorly dislocated position in patients with posterior fracture dislocation of the shoulder can be challenge to a trauma surgeon. With this novel technique, humeral head is reduced through deltopectoral approach without increasing the risk to the remaining blood supply.
