Trapeziometacarpal Osteoarthritis Clinical Trial
Official title:
Comparison Between Hemitrapeziectomy and Total Trapeziectomy With Ligament Reconstruction and Tendon Interposition in Trapeziometacarpal Osteoarthritis II-III Eaton-Littler
1. Introduction:
Investigators think that surgery with preservation of healthy joints
(hemitrapeziectomy) in trapeziometacarpal osteoarthritis without affecting
sapho-trapezo-trapezoid joints, is better for scaphoid stability by preventing its
collapse and thus preserving the stability of the carpus.
2. Objectives and Hypothesis:
Ligamentoplasty with partial trapeziectomy in grades II-III Eaton presents better
results in the pollicis-lateral pinch (key pinch) strength than ligamentoplasty with
total trapeziectomy.
Main Objective:
To demonstrate using the dynamometer that the postoperative key pinch strength higher
using ligamentoplasty with partial trapeziectomy in grades II-III Eaton.
Secondary objectives:
To measure the collapse of the first column of thumb using calibrated radiographic
analysis. Pain (E.V.A Scale). Range of motion (measured with goniometer). Quality of
life (DISABILITIES OF THE ARM, SHOULDER AND HAND questionnaire).
3. Methodology:
It is a single-center randomized trial, parallel-group, in which two types of surgical
techniques (TT - TP) will be compared. Patients will be randomized in this two techniques
will be followed for one year, in routine clinical practice.
