Augmented latissimus dorsi transfer: initial results in patients with massive irreparable posterosuperior rotator cuff tears.

Background: The surgical treatment of irreparable massive rotator cuff tears is challenging. The purpose of the present study was to report the initial outcomes after a modified latissimus dorsi transfer (LDT) augmented by acellular dermal allograft (ADA).

Methods: This retrospective study includes 24 patients managed with LDT using ADA augmentation as a bursal-sided onlay between March 2009 and December 2015.

Accurate Measurement of Greater Tuberosity Displacement Without Computed Tomography: Validation of a Method on Plain Radiography to Guide Surgical Treatment.

Introduction: Residual displacement of greater tuberosity (GT) fractures has been shown to negatively affect shoulder function. However, accurate measurement of GT displacement remains a problem with errors up to 13 mm on plain radiography (XR). A new GT ratio for measuring fracture displacement on XR is described, validated, and correlated with computed tomography (CT) and surgical decision making.

Occlusion of the artery of Adamkiewicz after hip and knee arthroplasty.

The artery of Adamkiewicz is the most significant tributary of the anterior spinal artery in the midthoracic region; the occlusion of this artery results in a well-described phenomenon consisting of paraplegia with loss of the sensation of pain, temperature, and touch as well as loss of sphincter control. Proprioception and vibration sense are typically preserved. Although this phenomenon has been associated with several surgeries as well as preexisting aortic abnormalities, the literature thus far has not reported this as a complication of hip or knee arthroplasty.
