The patients are divided into two groups: one in which a Maia trapeziometacarpal prosthesis is implanted, and the other in which the standard technique of trapeziectomy and tenosuspension plasty is performed according to the Burton-Pellegrini technique.The follow-up of the patients is one year, and functionality (measured with the Quick Dash test) and pain (measured with the VAS scale) are compared throughout this period.This study has a sample size of 62 patients, 31 per group. Other secondary variables are also evaluated, such as strength and mobility of the thumb trapeziometacarpal joint (measured with the Kapandji index).",[25],"Rizarthrosis",[27,28,29,30],"Thumb","osteoarthritis","prosthesis","trapeziectomy","RECRUITING","2025-07-28",{"date":34,"type":35},"2025-08-03","ACTUAL",{"date":37,"type":35},"2022-06-01",{"date":39,"type":19},"2025-11-01",{"name":41,"class":42},"Parc de Salut Mar","OTHER"]
