Classification of rotator cuff lesions.

Among various studies reporting the outcome of surgical repairs of rotator cuff tears, comparisons are very difficult because of the absence of a classification system. A proposed classification system takes into account the extent of the tear, its topography in the sagittal and frontal planes, the trophic quality of the muscle, and the integrity of the long head of the biceps. The new classification system exploits the advances in diagnostic imaging and is useful in the assessment of nonoperatively treated patients.
