during a cross-sectional study, patients who were admitted to the orthopedic department of the urmia university of medical sciences were asked about opium/opioid abuse. demographic characteristics, the pattern of consumption, the substance, the duration of the use, the duration of hospital stay and the cause of their injuries were recorded. among 2,867 patients, 74 (2.5%) patients (71 men and 3...

background: increased costs and mortality associated with inappropriate blood transfusions have led to investigations about blood request and blood transfusion techniques. we investigated the transfusion status in patients who underwent orthopedic surgery in poursina hospital (rasht, iran) to optimizing blood usage and determine if a scheduled transfusion program for every orthopedic surgery co...

background:   many of the patients with tethered cord syndrome (tcs) are admitted because of neurological symptoms, while some are admitted because of their orthopedic, urologic, anorectal, and dermatologic manifestations.consequently, this study aimed to evaluate the importance of early diagnosis and treatment of tethered cord syndrome on patient outcome. methods: fourty-three patients who und...

Virtual Environments have been used to train medical surgeons in orthopedic surgery. Using such simulators, residents and surgeons can develop or improve their skills in specific orthopedic surgical processes. In this section 2 of this report, a review of related work in the use of virtual environments in various surgical fields are presented. This includes orthopedic surgery, heart surgery, an...

Running biomechanics play an important role in the development of injuries. Performing a running biomechanics analysis on injured runners can help to develop treatment strategies. This article provides a framework for a systematic video-based running biomechanics analysis plan based on the current evidence on running injuries, using 2-dimensional (2D) video and readily available tools. Fourteen...

In this article, we describe the basic knowledge about shoulder biomechanics, which is thought to be useful for surgeons. Some clinical reports have described that the excellent outcome after cuff repair without acromioplasty and a limited acromioplasty might be enough for subacromial decompression. It was biomechanically demonstrated that a 10-mm medial shift of the tendon repair site has a mi...

The subject of symmetry has always been a matter interest in biomedicine, particularly exercise physiology and biomechanics [...]
