OBJECTIVE To compare the Lichtenstein, tension-free mesh, and the Shouldice, 4-layer Bassini repair of the inguinal hernia. DESIGN Prospective randomized clinical trial. SETTING A private suburban hernia center. PATIENTS Six hundred seventy-two men with inguinal hernias, aged 20 to 90 years, seen at the hernia center between January 1, 1990, and December 31, 1995. INTERVENTIONS Slightly...

OBJECTIVES To assess the results of inferior capsular shift for multidirectional instability of the shoulder in athletes. METHODS Multidirectional instability was surgically corrected in 53 shoulders in 47 athletes who engaged in contact sports. A history of major trauma was found in eight patients, the others having had minor episodes. Before surgery, all patients had complex combinations of...

In today’s marketplace the repairs of various components especially long lead items for turbomachinery equipment are an important factor for the maintaining reliability and performance of the equipment. This paper will describe repairs applied to compressors

Fifteen to 20 years ago, transversalis and Shouldice Hospital repairs were standard, with a 4% to 6% rate of recurrence. With a focus on recurrence, various mesh repairs were proposed to reduce the incidence of recurrence. With these repairs, an increased incidence of inguinodynia due to the entrapment of the nerves proximate (adjacent) to the mesh has been observed. Many surgeons doubted its e...

This paper is concerned with the dependence structure of a multi-component, cumulative damage shock model, in which a system of components is subject to correlated shock damages and group repairs. A component fails when its cumulative damage exceeds a given threshold, and is then replaced by a new component. We incorporate a block maintenance schedule that simultaneously performs imperfect repa...

BACKGROUND The success rate of rotator cuff repairs is variable. This study was performed to evaluate the ability of recombinant human bone morphogenetic protein-12 (rhBMP-12), administered in several carriers, to accelerate healing in a sheep model of rotator cuff repair. METHODS Local retention of tracer amounts of radiolabeled rhBMP-12, added to non-radiolabeled rhBMP-12 delivered in buffe...
