Background: The treatment of rhizarthritis involves several surgical techniques; among them, bioabsorbable scaffolds have begun to be proposed to avoid the use of other biological tissues or artificial permanent devices. Methods: In this study, we evaluated the long-term outcomes of poly-ld-lactic acid scaffold in interposition arthroplasty in a series of patients treated in our department. Results: Strength, range of motion, and pain improved after the intervention and lasted over the years; nonetheless, most of the radiographs showed a progressive collapse of the first metacarpal. Conclusions: Despite radiological findings, we believe that poly-ld-lactic acid scaffold can be considered a good alternative to traditional trapeziectomy with tendon interposition and suspensionplasty, with long-lasting satisfactory clinical results.
