| Trapeziometacarpal joint pain will be assessed using the Visual Analogue Pain Scale (VAS). This is a unidimensional measure of pain intensity that has been widely used in various adult populations. The VAS pain scale is a continuous scale consisting of a 10-cm-long horizontal line anchored by two verbal descriptors: one for each extreme symptom (no pain, with a score of 0) and the worst imaginable pain, with a score of 100);Handgrip strength will be measured using a Jamar dynamometer. The assessment follows the American Hand Therapists Society protocol, with the patient seated, feet supported, elbow at 90 degrees, shoulder adducted, and forearm and wrist in neutral. Three measurements are taken of each upper limb, with a rest of ten seconds to one minute between each measurement. The final result is calculated by averaging the three measurements;Pinch strength, which will be assessed by a finger dynamometer, is used. To assess the pulp-to-pulp and three-point pinch, the forearm is held pronated. Three measurements will be taken with each upper limb for each type of pinch, and the average of these three measurements will be calculated;Opposition degree, which will be assessed using the Kapandji Index, which consists of a ten-point scale that objectively measures the functional opposition movement of the thumb. It has significant clinical implications, since a large proportion of hand function depends on this thumb movement. The score ranges from zero, when there is no movement or when the thumb pad reaches the lateral aspect of the proximal phalanx of the index finger, to 10 when the thumb pad reaches the distal palmar crease at the ulnar border;Operative failure, which will be confirmed when it is verified, at any time postoperatively, the maintenance of persistent pain, located in the topography of the trapeziometacarpal joint or other complications that require an additional surgical procedure and/or hospital admission after discharge, will be considered treatment | — |
