Impact of fractured tibia implant fixation devices on bone stiffness during bending test.

This study focuses on evaluating the failure resistance of a previously reduced tibia with internal fixation implants as PLate (PL) or InterMedullary Nail (IMN), subjected later to a tibial lateral trauma. To replicate this type of trauma, which can be caused by a road accident, a three-point bending test is considered using experimental tests and numerical simulations. The withstand evaluation of the tibia-PL and tibia-IMN structures was conducted by following the load transfer through, the bone and the used implants.

Surgical site infection in spinal metastasis: incidence and risk factors.

Background: Surgical site infection (SSI) in spinal metastasis surgery represents the most common postoperative surgical complication with high morbidity and mortality.

Objective: This study aims to evaluate the incidence of SSI in spinal metastasis surgery and its risk factors.

Study Design: This is a retrospective analysis of a prospectively collected data.

Tibio-femoral joint contact in healthy and osteoarthritic knees during quasi-static squat: A bi-planar X-ray analysis.

The aim of this study was to quantify the tibio-femoral contact point (CP) locations in healthy and osteoarthritic (OA) subjects during a weight-bearing squat using stand-alone biplanar X-ray images. Ten healthy and 9 severe OA subjects performed quasi-static squats. Bi-planar X-ray images were recorded at 0°, 15°, 30°, 45°, and 70° of knee flexion.
