Manejo de la inestabilidad acromioclavicular crónica

Abstract

The acromioclavicular joint represents the link between the clavicle and the scapula, responsible for the synchronized dynamics of the shoulder girdle. Chronic acromioclavicular joint instability involves the occurrence of changes in the anatomical orientation of the scapula, a situation that leads to changes in muscle kinematics that could result in chronic pain. Several surgical strategies for the management of patients with chronic and symptomatic acromioclavicular joint instability have been described. The range of possibilities includes anatomical and non-anatomical techniques, open and arthroscopy-assisted surgery, and biological and synthetic grafts. Surgical management of chronic acromioclavicular joint instability should involve the reconstruction of the torn ligaments, as it is accepted that after 3 weeks from the injury, these structures lack healing potential.This paper describes a review of the literature as regards to the management of chronic acromioclavicular instability.
