BACKGROUND Few reconstructive methods to treat displaced acromioclavicular separations have been evaluated using kinematic data. HYPOTHESIS The modified Weaver-Dunn reconstruction restores intact acromioclavicular joint motion during passive scapular plane abduction. STUDY DESIGN Controlled laboratory study. METHODS Acromioclavicular joint motion was recorded during passive humeral elevat...

Background: An oscillating bone saw is rarely used to perform laminectomy. The purpose of this study was to describea relatively quick and harmless technique for multilevel laminectomy in patients with lumbar spinal stenosis (LSS) usingan oscillating bone saw to find out how this instrument affects the time of surgery and rate of complications.Methods: This prospective study w...

Sagittal bone saws are used by orthopedic surgeons for resection of bone; for example in total joint arthroplasty of the hip and knee. In order to prevent damage to surrounding tissue, sagittal saw blades typically oscillate through a small angle, resulting in reduced cutting rates due to short stroke lengths. To improve bone cutting efficiency, sagittal saws oscillate at high speeds, but this ...

The prevalence of pneumoconiosis varies from 15–30% in various parts of India (1). Occupational asthma may account for about 10% of adult asthma (2). Asthma associated with work is being recognized with increased f requency in carpenters , saw mi l l workers and furn i tu re makers . The cause for occupa t iona l as thma i s wood/saw dus t . Ear l ie r s tud ies have documented increased incide...

The propagation process of the surface acoustic waves (SAW) and pseudo-surface (PSAW) in a bonded layered structure 41° YX-cut LiNbO3 crystal/Si(100) crystal was investigated. scanning electron microscopy (SEM) method,in low-energy secondary electrons registration mode, made it possible to visualize SAW PSAW LiNbO3/Si structure. bulk were compared. It demonstrated that velocities exceed typical...

OBJECTIVES To evaluate the ability of an alignment jig/saw guide to reproduce appropriate osteotomy positions in the tibial plateau leveling osteotomy (TPLO) in the dog. METHODS Lateral radiographs of 65 clinical TPLO procedures using an alignment jig and freehand osteotomy performed by experienced TPLO surgeons using a 24 mm radial saw blade between Dec 2005-Dec 2007 and Nov 2013-Nov 2015 we...
