[Is chronic, untreated scapho-trapezoid arthrosis after resection arthroplasty of the carpometacarpal joint clinically relevant?].

Basal joint arthrosis and scapho-trapezio-trapezoid arthrosis (triscaphe-arthrosis) are common degenerative diseases with proven surgical treatment. Besides the extirpation of the trapezium during the resection-suspension arthroplasty, we have performed additional fusion of the scaphoid and the trapezoid (ST arthrodesis) in patients with heavy arthrotic changes in both locations. But the combination of these two surgical procedures results in a prolonged rehabilitation and may lead to more complications, e.
