Surgical therapy of conservatively exhausted rhizarthrosis - total joint replacement or resection arthroplasty? A systematic review

Rhizarthrosis is a common degenerative disorder of the carpometacarpal joint of the thumb, significantly impairing hand function due to pain and loss of mobility. While conservative and joint-preserving measures are the first-line treatment in early stages, advanced disease often requires surgical intervention. The aim of this study was to evaluate and compare the clinical outcomes, functional results, and complication profiles of resection arthroplasty versus latest generations of thumb carpometacarpal joint prostheses. Resection arthroplasty has proven to be a reliable therapy, providing effective pain relief and high patient satisfaction. Latest generations of thumb carpometacarpal joint prostheses demonstrate low rates of loosening and dislocation, along with advantages such as faster rehabilitation, preservation of thumb length, and good functional outcomes. The choice of procedure should be individualized, considering age, activity level, and functional requirements.
