Methods: Electronic databases such as PubMed, Embase, Web of Science, and Cochrane were systematically searched for publications concerning obesity and shoulder arthroplasty. The Newcastle-Ottawa scale criteria were used to evaluate the study's quality.
Objective: To investigate the maximum anti-pullout force and stress distribution of cortical bone trajectory (CBT) screws during screw pullout after contacting different cortical bone layers by finite element analysis (FEA) based on Abaqus software, and to provide evidence for increasing screw holding force during CBT screw implantation in clinical practice.
Methods: Based on the plain CT data of lumbar spine of a healthy male volunteer who visited the Fourth People's Hospital of Guiyang in June 2022, and the standard screw parameters according to cortical bone trajectory screws. A three-dimensional model of L4 vertebral body and CBT screw was established.
Background: Studies of clinical outcomes that compare the Medial Pivot design (MP) with the Posterior-Stabilized design (PS) were controversial. The meta-analysis was performed to summarize existing evidence, aiming to determine whether MP was superior to PS prosthesis.
Methods: Search strategies followed the recommendations of the Cochrane collaboration.
