Introduction:

Different studies relate the diagnosis of high-resolution ultrasound with the arthroscopic diagnosis of the rotator cuff. Both methods are favorable and show high sensitivity and specificity when they are compared.

Objective:

To establish diagnostic efficacy between the findings of high-resolution ultrasound and the arthroscopic diagnosis of partial and complete ruptures of the rotator cuff.

Methods:

A cross-sectional analytical study was carried out, aimed at evaluating the diagnostic efficacy of high-resolution ultrasound in patients of Dr. Antonio Luaces Iraola Provincial General Teaching Hospital, in Ciego de Ávila, with a clinical diagnosis of partial and complete ruptures of the rotator cuff, from January 2016 to January 2019. The universe consisted of 62 patients with a clinical diagnosis of rotator cuff rupture who presented surgical indications, and who were also indicated for an imaging study with high-resolution ultrasound and, subsequently, performed arthroscopic surgery, taken as a criterion of truth.

Results:

The male sex predominated, with an average age lower than those corresponding to female sex. The diagnostic findings by both methods showed agreement in more than two thirds of the patients who presented partial and complete ruptures of the rotator cuff’s thickness. Ultrasonography, according to the method used, was an effective diagnostic tool for partial and complete ruptures of the rotator cuff’s thickness.

Conclusions:

High-resolution ultrasound showed an adequate correlation in the diagnosis of partial or complete ruptures of rotator cuff, as confirmed by arthroscopy. It is considered an effective diagnostic means.
