Purpose: The research analyses the strength of metallic implants in posterior spinal instrumentation for the treatment of thoracolumbar fractures, considering extended and short fixation techniques on the immediate post-surgical load. Considering that short fixation may bring the advantage of a less invasive surgical procedure to the patient and may also result in lower costs, this evaluation becomes necessary.
Methods: Three-dimensional modelling of the thoracolumbar spine was initially performed.
Objectives: To evaluate and compare bone tunnel positioning in anterior cruciate ligament (ACL) reconstruction surgery using the arthroscopic technique and the open technique consisting of arthrotomy.
Method: A comparative retrospective study on 70 patients with ACL lesions was conducted. Thirty-five patients underwent ACL reconstruction by means of the open technique and 35 by means of the arthroscopic technique using an anteromedial portal.
