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

Abstract

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. We recorded the type of implant used (ie, single vs dual mobility; Ivory vs Moovis), and recorded dislocations and complications requiring additional surgery. Results: We recorded significantly more prosthetic dislocations in the single-mobility (Ivory) group (n = 6, 9.7%), compared with the dual-mobility (Moovis) group (n = 1, 1.4%). The most frequent complication requiring additional surgery was De Quervain tendinitis (n = 13, 9.6%). Conclusions: This study shows that a dual-mobility TMC prosthesis has significantly less postoperative dislocations compared with its single-mobility counterpart. We identity De Quervain tendinitis as the most frequent complication requiring additional surgery.

Biometric analysis hand parameters in young adults for prosthetic hand and ergonomic product applications

“…Consequently, individuals with hand loss experience significant challenges and limitations, affecting their quality of life and impeding their participation in social and occupational activities [ 14 ]. Prosthetic hands have been developed to address these challenges and enhance the well-being of individuals with hand loss, enabling them to regain their independence and engage in daily activities [ 15 ].…”

“…However, there are significant issues that need to be addressed in protective hand support products and prosthetic hand design, as they often present challenges and limitations that hinder their usability. High cost, bulky and heavy designs, limited range of motion, skin irritation, and discomfort due to excessive sweating are some of the limitations associated with traditional prosthetic hands [ 13 , 15 ].…”

“…Recently, three-dimensional (3D) printing technology has gained popularity as cost-effective and lightweight alternatives in prosthetic hand development. Utilizing 3D technology allows for the production of customizable and affordable support products and prosthetic hands [ 15 , 16 ]. An important criterion in prosthetic hand design is anatomical compatibility.…”
