Resumen
Introducción

El tratamiento de la artrosis trapeciometacarpiana encaminado a mejorar el dolor y mantener la movilidad del pulgar, comprende desde el tratamiento conservador hasta el quirúrgico, con múltiples técnicas quirúrgicas, como la interposición de Artelon®. El objetivo del trabajo es mostrar una serie de pacientes tratados con esta técnica.

Materiales y métodos

Se evaluó una serie de casos operados con Artelon. Se clasificaron radiológicamente según Eaton y Littler y se evaluaron las variables de arcos de movilidad y de dolor según la escala visual análoga.

Resultados

12 pacientes fueron evaluados (14 casos), con edad promedio de 57 años y de ellos el 91% mujeres. El dolor preoperatorio en promedio era de 8 y el posoperatorio de 1. La movilidad posoperatoria fue buena en general, con una flexión-extensión de 32° y abducción de 33°. Se encontraron 2 complicaciones menores: en un paciente, aflojamiento del tornillo proximal colocado en el trapecio y, en el otro, una subluxación leve del metacarpiano sobre el trapecio. El 100%, de los pacientes, estaba satisfecho con la cirugía.

Discusión

Se lograron buenos resultados en cuanto a movilidad y mejoría del dolor. Es un procedimiento relativamente sencillo, de corta duración y que ha mostrado buenos resultados pero no supera las técnicas de suspensión tendinosa. Es, en definitiva, otra herramienta más en la solución de la artrosis trapeciometacarpiana.

Summary
Introduction

The objective of the treatment of metacarpal trapeziumosteo arthritisis aimed at improving pain and maintaining mobility of the thumb. This ranges from conservative to surgical treatment with multiple surgical techniques, among these the filing of Artelon®. The objective of this work is to show a series of patients with this modality of treatment.

Materials and Methods

We evaluated a number of surgical cases with Artelon. We evaluated and classified them according to the Eatonand Littler radiologically assessed variables, range of motion and pain on a visual analogue scale.

Results

12 patients were evaluated (14 cases), mean age 57 years and 91% were women. The pain was 8/10 preoperativeand postoperative average of 1/10. Postoperative mobility was generally good, with flexion- extension of 32° and abduction of 33°. We found 2 minor complications that were placed proximal screw loosening on the trapeze in one patient and in another amildsubluxation of the metacarpalon thetrapezium. 100% of patients were satisfied with surgery.

Discussion

Good results were achieved in terms of mobility and pain relief. It is a relatively short and simple procedure, and has shown good results, but it does not exceeds tendon suspension techniques. It's definitely an other tool in the solution of the trapeziummetacarpal osteoarthritis.
