Results showed arthroscopic partial trapeziectomy with thermal shrinkage and K-wire fixation may be an effective and safe procedure for thumb carpometacarpal joint arthritis.
“[This procedure] successfully maintained improvement of functional outcome, preserved the mechanical height of the trapezium, increased the [carpometacarpal] CMC space and decreased metacarpal subluxation without the need for soft tissue interposition and ligament reconstruction,” the authors wrote. “However, a surgeon skilled in arthroscopy should perform the procedure.”
Researchers collected preoperative and postoperative Modified Mayo Wrist Score, DASH score, radiographic changes and associated complications among 24 patients with thumb carpometacarpal joint arthritis who underwent arthroscopic partial trapeziectomy combined with thermal shrinkage and K-wire fixation between February 2013 March 2014.
Overall, 16 patients completed 5 years of functional score and radiographic follow-up, according to researchers. Results showed significant improvements in the Modified Mayo Wrist Score and DASH score from preoperatively to postoperatively. Researchers found significant differences in the carpometacarpal joint distance, scaphoid-metacarpal distance, trapezium-metacarpal distance and metacarpal prominence distance between preoperative and postoperative evaluation of radiographic changes.
