Abstract
INTRODUCTION
Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) arthroplasty is a reliable surgical procedure for the treatment of thumb carpometacarpal osteoarthritis, which provides good long-term outcomes. However, it remains unclear when the greatest benefit of this procedure can be obtained, and how long these benefits will continue. Therefore, we investigated the middle- to long-term advantages of this procedure by analysing the chronological changes in clinical outcomes by following the same patients from 1 year to a median 5 years after trapeziectomy with LRTI.
MATERIALS AND METHODS
Sixteen thumbs that completed consecutive clinical and radiographic evaluations preoperatively, 1 year, 2 years, 3 years, and median 5 years (range 4-8 years) after trapeziectomy with LRTI were included in this study. We investigated grip strength, pinch strength, range of motion (ROM) of the thumb, a visual analogue scale for pain, Disabilities of Arm, Shoulder and Hand (DASH) score, Hand20 questionnaire score, trapezial space height, and trapezial space ratio at every time point.
RESULTS
Hand strength (grip, pulp, and lateral pinch), palmar abduction, DASH score, and Hand20 questionnaire score were improved at 1 year postoperatively while the radial abduction showed significant improvement at the final follow-up. Moreover, pulp pinch strength, DASH score, and Hand20 questionnaire score continued to improve significantly from 1 year postoperatively to the final follow-up. Conversely, trapezial space height and ratio continuously decreased up to the final follow-up.
CONCLUSIONS
Trapeziectomy with LRTI consecutively improved the pinch strength, ROM of the thumb, DASH score, and Hand20 questionnaire score up to 5 years postoperatively. It also maintained the improvement of the other clinical outcomes up to 5 years postoperatively except for radiological findings.
