PURPOSE The objective of this study was to compare an arthroscopic suture technique with an open posterior screw fixation technique, by use of mechanical testing, for the treatment of posterior cruciate ligament (PCL) tibial bony avulsion. METHODS We split 10 intact human cadaveric knee pairs (20 knees) into 2 groups (A and B) with 1 knee from each pair(More)
OBJECTIVES To compare the accuracy of tunnel placement and graft isometry for anterior cruciate ligament reconstruction performed using a computer-assisted navigation system (Orthopilot) and using traditional instruments. METHODS The anterior cruciate ligament was removed intact from 36 pairs of human cadaver knees. From each pair, one knee was randomized(More)
OBJECTIVE To test an intra-articular reconstruction of the anterior cruciate ligament of the knee in 10 human cadavers by replacing 2 anterior cruciate ligament bundles, with the purpose of producing a surrogate that would be structurally more similar to the anatomy of the anterior cruciate ligament and would provide the knee with more stability. METHODS(More)
INTRODUCTION Anterior cruciate ligament ruptures are frequent, especially in sports. Surgical reconstruction with autologous grafts is widely employed in the international literature. Controversies remain with respect to technique variations as continuous research for improvement takes place. One of these variations is the anatomical double bundle(More)

Cancer of the oral cavity are 4% of all cancers, being in 8th place in males and 11th in females. The world incidence in male sex is 7.9:100,000 and 2.2:100,000 in females. Squamous cell carcinoma is the most frequent, corresponding to 90-95% of the cases and tongue, lips and floor of the mouth are the most common sites. Fifty-four patients were surgically(More)
