PurposeTo investigate whether palmaris longus interposition or flexor carpi radialis ligament reconstruction and tendon interposition improve the outcome of trapezial excision for the treatment of basal joint arthritis after a minimum follow-up of 5 years.MethodsWe randomized 174 thumbs with trapeziometacarpal osteoarthritis into 3 groups to undergo simple trapeziectomy, trapeziectomy with palmaris longus interposition, or trapeziectomy with ligament reconstruction and tendon interposition using 50% of the flexor carpi radialis tendon. A K-wire was passed across the trapezial void and retained for 4 weeks, and a thumb spica was used for 6 weeks in all 3 groups. We reviewed 153 thumbs after a minimum of 5 years (median, 6 y; range, 5-18 y) after surgery with subjective and objective assessments of thumb pain, function, and strength.ResultsThere was no difference in the pain relief achieved in the 3 treatment groups, with good results in 120 (78%) patients. Grip strength and key and tip pinch strengths did not differ among the 3 groups and range of movement of the thumb was similar. Few complications persisted after 5 years, and these were distributed evenly among the 3 groups. Compared with the results at 1 year in the same group of patients, the good pain relief achieved was maintained in the longer term, irrespective of the type of surgery. While improvements in grip strength achieved at 1 year after surgery were preserved, the key and tip pinch strengths deteriorated with time, but the type of surgery did not influence this.ConclusionsThe outcomes of these 3 variations of trapeziectomy were similar after a minimum follow-up of 5 years. There appears to be no benefit to tendon interposition or ligament reconstruction in the longer term.Copyright © 2012 American Society for Surgery of the Hand. Published by Elsevier Inc.
