A retrospective review of 115 cases of surgically-treated trapeziometacarpal osteoarthritis.

摘要: The trapeziometacarpal joint is among the main targets for osteoarthritis at hand. objective of surgical treatment to obtain a painless, stable, and mobile joint. One hundred fifteen cases treated either by GUEPAR prosthesis (n = 90; group A) or excision trapezium followed ligament reconstruction tendon interposition 25; B) were studied retrospectively. choice between two procedures was based on number clinical radiological criteria. Of 90 A patients, 79 reevaluated, after mean follow-up 5.75 years. Clinical results good in 92% cases. Loosening cup seen seven cases, which three (3.8%) implantation Swanson within years first procedure. Six patients had loosening metacarpal component only, stable over time no adverse effect results. 25 B 19 3.5 18 cases; height scaphometacarpal space decreased 51% versus its preoperative value. We conclude that provides with low revision rate deserves be widely used least 7 mm height. Indications excision-reconstruction-interposition procedure include severe osteoarthritis, less than mm, younger age, intensive hand use.
