Effectiveness of Trapeziometacarpal Splint

Federal University of São Paulo60 enrolled

Overview

The trapeziometacarpal osteoarthritis is a degenerative or inflammatory joint that affects the trapeziometacarpal joint (TMC) of the thumb. Its main symptom is pain that leads to difficulty in manual function and decrease the patient's quality of life. Immobilization of TMC thumb joint by bracing has been effective in reducing pain and improving function. Objective: To compare the effectiveness between day and night functional splint for patients with trapeziometacarpal osteoarthritis in improving pain and function

Randomized clinical trial, and blind where selected 60 patients diagnosed with trapeziometacarpal osteoarthritis.Os patients were assessed by a blinded evaluator at the beginning of treatment and after 45, 90 and 180 days in relation to pain, thumb range of motion, strength hold, tweezers, dexterity, function and satisfaction.

Interventions

Day SplintDEVICE

A thermoplastic splint was confected for each participant to stabilize the trapeziometacarpal joint, maintaining the pulp of the distal phalange of the index finger free for gripping with the other fingers and leaving the thumb in a functional position. In this group the slint was used during the daily life activities.
