125. Effects of Extrinsic Muscle Integrity on Latissimus Dorsi Transfer for Irreparable Rotator Cuff Tears: a Simulation Study

Abstract

Massive rotator cuff tears are one of the most common shoulder problems among the elderly, leading to pain and disability of the upper extremity. Muscle transfer, which can compensate for some of the deficits, has been advocated as the primary treatment of irreparable massive rotator cuff tears or as a salvage procedure after failed repairs. Latissimus dorsi transfers offer a promising solution in the treatment of irreparable posterosuperior rotator cuff tears, resulting in pain relief and function improvement of patients with the tears. However, the clinical results are variable and the factors which determine outcome are poorly understood. Prior studies have revealed that the functional outcomes of latissimus dorsi transfers were adversely affected if there was a deficit in deltoid and teres minor muscles [1, 2]. For the patient with a deltoid injury, the transfer that follows a failed rotator cuff repair produces less functional improvement than if the transfer is performed as the primary treatment to repair the rotator cuff. It was revealed that the presence of a tear of the teres minor muscle might have some predictive value prior to surgery with regard to motion and function [1], whereas the degree of fatty infiltration also played a critical role after the transfer [2]. Outcomes of muscle transfers have been reported in the literature, but the effects of extrinsic muscle integrity on the functional outcomes in the latissumus dorsi transfer have not been addressed quantitatively. The purpose of this work was to study the effects of the extrinsic muscle integrity on the functional outcomes in the latissumus dorsi transfer using a three-dimensional integrated model of the upper extremity [3]. First, the effects of extrinsic muscle integrity on the preoperative functions of shoulders with massive rotator cuff tears were investigated. Second, these effects on the functional outcomes of muscle transfers were evaluated quantitatively. Copyright © 2008 by ASME

Abstract

Objectives: Pelvic circumferential compression devices are commonly used in the acute treatment of pelvic fractures for reduction of pelvic volume and initial stabilisation of the pelvic ring. There have been reports of catastrophic soft-tissue breakdown with their use. The aim of the current investigation was to determine whether various pelvic circumferential compression devices exert different amounts of pressure on the skin when applied with the force necessary to reduce the injury. The study hypothesis was that the device with the greatest surface area would have the lowest pressures on the soft-tissue.Methods: Rotationally unstable pelvic injuries (OTA type 61-B) were surgically created in five fresh, whole human cadavers. The amount of displacement at the pubic symphysis was measured using a Fastrak, three-dimensional, electromagnetic motion analysis device (Polhemus Inc., Colchester, VT). The T-POD, Pelvic Binder, Sam Sling, and circumferential sheet were applied in random order for testing. The devices were applied with enough force to obtain a reduction of less than 10mm of diastasis at the pubic symphysis. Pressure measurements, force required, and contact surface area were recorded with a Tekscan pressure mapping system.Results: The mean skin pressures observed ranged from 23 to 31kPa (173 to 233mm of Hg). The highest pressures were observed with the Sam Sling, but no statistically significant skin pressure differences were observed with any of the four devices (p>0.05). The Sam Sling also had the least mean contact area (590cm(2)). In greater than 70% of the trials, including all four devices tested, skin pressures exceeded what has been shown to be pressure high enough to cause skin breakdown (9.3kPa or 70mm of Hg).Conclusions: Application of commercially available pelvic binders as well as circumferential sheeting commonly results in mean skin pressures that are considered to be above the threshold for skin breakdown. We therefore recommend that these devices only be used acutely, and definitive fixation or external fixation should be performed early as patient physiology allows. There may be some advantage of use of a simple sheet given its low cost, versatility, and ability to alter contact surface area. [ABSTRACT FROM AUTHOR]
