Assessment of Intraoperative Rotational Alignment of Closed Locked Intramedullary Nailing for Humerus Fractures.

Intramedullary nailing of humerus fractures has evolved over the past half century and has grown in popularity especially for the polytraumatized patient. The importance of restoring appropriate rotational alignment is equivalent to that of restoring sagittal and coronal alignment to decrease the risk of shoulder degenerative changes and limit range of motion discrepancy from the contralateral limb. This technique is designed to introduce an intraoperative fluoroscopic method to obtain adequate rotational alignment of humeral shaft fractures treated with closed antegrade humeral locked nailing.
