Thumb Carpometacarpal Implant Arthroplasty.

Thumb carpometacarpal implant arthroplasty aims to preserve thumb length and motion and to provide pain relief and functional recovery after a short postoperative time. For several decades, implant arthroplasty has been performed with total trapeziometacarpal joint prosthesis using the concept of "ball-and-socket" joint. More recently, pyrocarbon implants used as hemiarthroplasty or interposition arthroplasty have been proposed.

Dual mobility trapeziometacarpal prosthesis: a prospective study of 107 cases with a follow-up of more than 3 years.

We report the results of a prospective study using a dual mobility trapeziometacarpal prosthesis (Touch®) in 107 patients with a minimum follow-up of 3 years. One-hundred and two patients (95%) were very satisfied or satisfied with the functional outcomes and the mean pain intensity in visual analogue scale decreased from 7.4 to 0.

Surgical approaches to the trapeziometacarpal joint for the insertion of implants and prostheses (non-arthroscopy).

The two approaches most often used for placing implants and trapeziometacarpal prostheses are the laterodorsal approach and the lateropalmar approach. The advantages and disadvantages of these two approaches are set out. Each one allows optimal joint exposure while preserving or repairing the peritrapezial musculotendinous structures.
