TL;DR
This study compared two surgical techniques for treating severe thumb arthritis and found both to be equally effective in improving function and reducing pain.
Contribution
The study provides a direct comparison of trapezius resection arthroplasty with tendon interposition versus the Kuhns technique for rhizarthrosis.
Findings
Both surgical techniques showed good functional and pain outcomes without significant differences.
No complications required additional surgeries in either group.
TASD and QuickDASH scores were positively correlated, indicating their effectiveness in assessing disability.
Abstract
Objective This study aimed to evaluate and compare the clinical and functional outcomes of two surgical procedures performed in patients with severe grade III and IV rhizarthrosis. Methods We evaluated 39 patients who underwent two surgical techniques for rhizarthrosis treatment: trapeziectomy using the Kuhns technique or tendon interposition, with a minimum follow-up period of 6 months. The primary outcome assessment used the specific Trapeziometacarpal Arthrosis Symptoms and Disability (TASD) questionnaire, and the secondary outcome evaluation employed the shortened version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire and the visual analog scale (VAS). Results There was no statistically significant difference between groups in the TASD, QuickDASH, and VAS results, and both techniques demonstrated good functional and pain outcomes. No complication…
