Dislocation in Single-Mobility Versus Dual-Mobility Trapezometacarpal Joint Prostheses.

Background: The purpose of this study was to analyze postoperative dislocation rates in single-mobility (Ivory) versus dual-mobility (Moovis) trapezometacarpal (TMC) joint prostheses. Second, we report complications requiring additional surgery in these 2 types of prostheses.

Methods: We retrospectively obtained data of all patients receiving a TMC joint prothesis at our hospital between January 2015 and December 2020.

The prevalence of spinal epidural lipomatosis on magnetic resonance imaging.

Background: Spinal epidural lipomatosis (SEL) refers to an excessive accumulation of fat within the epidural space. It can be idiopathic or secondary, resulting in significant morbidity. The prevalence of SEL, including idiopathic and secondary SEL, and its respective risk factors are poorly defined.
