INTRODUCTION. The anterior cruciate ligament (ACL) is the most commonly injured major ligament of the knee (1). There are over 300,000 annually reported ACL injuries, a majority of which are complete ruptures (2). Long term success rates of 69-90% have been reported after arthrosopically-assisted ACL reconstruction, with a majority of failures related to graft fixation and surgical error. The e...

This study developed biomechanical models for hand breakaway strength that account for not only grip force but also hand-handle frictional coupling in generation of breakaway strength. Specifically, models for predicting breakaway strength for two commonly-used handle shapes (circular and rectangular handles) and varying coefficients of friction (COF) between the hand and handle were proposed. ...

OBJECTIVE To analyze the biomechanical and tomographic effects of hormone replacement therapy (HRT) on femurs from rats subjected to induced menopause. METHODS Forty-five adult Wistar rats were divided equally into three groups. The first and second groups consisted of rats subjected to oophorectomy, and the third was the control group, consisting of nonoophorectomized rates. After verifying ...

introduction: in this study the effects of low power helium-neon laser radiation on the cell population of open skin full thickness wound of rats were investigated from histological and biomechanical point of views. materials and methods: 90 male rats were randomly divided into control and two experimental groups. under general anesthesia and sterile conditions around open full thickness skin w...

OBJECTIVE The main purpose of the present study was to assess the radiographic, histological, and mechanical effects of gabapentin on fracture healing in a rat model of femur fracture. MATERIALS AND METHODS A standard transverse fracture of the mid-diaphysis was created. A total of 60 female Wistar-Albino rats with the mean age of 13.5 ± 1.2 weeks were used for this experimental trial. The ra...
