BACKGROUND To evaluate the severity of lumbar spine pain and the extent to which it affects everyday activities in patients treated surgically for scoliosis. MATERIALS AND METHODS Sixty female patients who had undergone Cotrel-Dubousset instrumentation for idiopathic scoliosis were asked to complete a questionnaire. The mean age of the patients at the time of surgery was 15.5 years, and the m...

Abstract Introduction Recently, a paper was published containing the long-term results of the first ‘modern’ double rod instrumentation, the Cotrel–Dubousset instrumentation. Results showed an unexpected high rate of reoperation of nearly 50% due to late infections or chronic back pain occurring after surgery. Further research into the longterm complications of spinal fusion surgery in adolesce...

objectives : cleaning and shaping of the root canal system is an important step in endodontic therapy. new instruments incorporate new preparation techniques that can improve the efficacy of cleaning and shaping. the aim of this study was to compare the efficacy of mtwo and race rotary file systems in straightening the canal curvature using only one file or the conventional method. materials an...

statement of problem: various factors are involved in causing inflammation following root canal treatment. controlling these factors may relieve the related pain. one of these factors is extrusion of debris beyond the apex. although debris extrusion happens in all instrumentation techniques, researchers have declared that in coronal flaring technique, there is minimum debris extrusion. purpose:...

conclusions it was concluded that ihlq might be a practical and useful tool for investigating hl for persian language speakers around the world. since hl is dynamic and its instruments should be regularly revised, further studies are recommended to assess hl with application of ihlq to detect its potential imperfections. results internal consistency and test-retest reliability (icc) of the fact...

Background: Oxford medial unicompartmental knee replacement (UKR) is indicated in patients with anteromedialosteoarthritis (AMOA) of the knee. Microplasty (MP) instrumentation was introduced in 2012 as an improvement overphase 3 instrumentation. Advantages of this instrumentation include conservative tibial cut, decreased tibial re-cut rateand improved component alignment. We report the results...
