Total joint arthroplasty of the thumb CMC joint.

Purpose Of The Study: Rhizarthrosis-osteoarthritis of the thumb carpometacarpal (CMC) joint is usually a primary idiopathic disease. Total joint arthroplasty (TJA) is one of the surgical treatment options for symptomatic advanced thumb CMC arthritis. This retrospective study aims to evaluate the mid-term functional and radiological results of TJA with the minimum follow-up period of 3 years after the surgery.

[Interposition and Suspension Arthroplasty of Carpometacarpal Joint of the Thumb Using the TIE-IN Implant].

PURPOSE OF THE STUDY The aim of the study was to present the surgical technique combining the interposition and suspension arthroplasty using the TIE-IN implant as a treatment option for advanced symptomatic to final stage rhizarthrosis. MATERIAL AND METHODS Since 2015 we have performed the interposition arthroplasty combined with suspension arthroplasty using the TIE-IN implant in 12 patients, mostly indicated for stage IV rhizarthrosis. In two cases stage III rhizarthrosis with concomitant trapezium destruction was present.

[Surgical Treatment for Advanced Rhizarthrosis. Comparison of Results of the Burton-Pellegrini Technique and Trapeziometacarpal Joint Arthroplasty].

Purpose Of The Study: The aim of the study was to compare results of the Burton-Pellegrini trapeziectomy with ligamentoplasty using the flexor carpi radialis tendon with those of trapeziometacarpal joint replacement in the treatment of advanced rhizarthrosis.

Material And Methods: A group of 17 patients, 15 men and two women, underwent trapeziectomy with ligamentoplaty; in 12 of them, the dominant hand was involved. The trapeziometacarpal joint prosthesis Beznoska was implanted in 11 patients (10 men and one woman) with seven dominant and four non-dominant hands.
