Biomechanical evaluation of intraosseous distal radioulnar joint prosthesis: A prosthesis designed based on Sauvé-Kapandji procedure.

Introduction: To avoid the DRUJ surgical procedures disadvantages, a new intraosseous distal radioulnar prosthesis designed on Sauvé-Kapandji procedure has been introduced. Stability of the prosthesis and biomechanics are to be evaluated in this article.

Materials And Methods: On a cadaveric study, during placement of the prosthesis, biometry of the bones, prosthesis stability (in axial and lateral tractions, wrist pronation and supination, and squeeze test), wrist range of motion before and after implantation, and radiographic evaluation were done on 16 cadavers.

Distal Radioulnar oint Prosthesis.

The distal radioulnar joint (DRUJ) prostheses have been available for many years and despite their superior outcomes compared to conventional DRUJ reconstructions in both short and long-term follow-ups, they have not become as popular as common hip and knee prostheses. In the current review article, at the first step, we discussed the applied anatomy and biomechanics of the DRUJ, and secondly, we classified DRUJ prostheses according to available literature, and reviewed different types of prostheses with their outcomes. Finally we proposed simple guidelines to help the surgeon to choose the appropriate DRUJ prosthesis.

Introduction and Early Outcomes of Intraosseous Distal Radioulnar Joint Prosthesis: A Pilot Study and a Technique on a New Design of the Sauvé-Kapandji Procedure.

Background: Different surgical procedures have been proposed for the treatment of Distal Radioulnar Joint (DRUJ) arthrosis and other conditions. This study aimed to introduce a new design of DRUJ prosthesis based on the Sauvé-Kapandji procedure followed by the evaluation of its short-term results. Darrach and Sauvé-Kapandji techniques are two well-known salvage procedures.
