Editorial Commentary: Does the Morphology of the Acromion Explain All Rotator Cuff Tears?

Radiographic Study on the Acromion Index and Its Relationship with Rotator Cuff Tears.

OBJECTIVE The purpose of this study was to evaluate the relationship between the lateral projection of the acromion and rotator cuff tears (RCTs) in the Brazilian population. METHODS The lateral projection of the acromion was measured using anteroposterior radiographs of the shoulders, carried out with the glenoid cavity in absolute profile and the humeral head in the neutral position or with...

Quantitative morphology of full thickness rotator cuff tears.

The occurrence of full thickness rotator cuff tears (RCTs) at time of death, the size and distribution of those tears among the tendons of the rotator cuff, and the anterior to posterior and medial to lateral dimensions of the RCTs were determined. A subset of 57 shoulders from a group of 414 were found to have full thickness rotator cuff tears. The three-dimensional coordinates of specific bon...

Tears of the Humeral Rotator Cuff

Massive tears of the rotator cuff.

Repair of massive rotator cuff tears is technically difficult but often feasible. Technical and biological challenges to a successful repair include inelastic poor-quality tendon tissue, scarring, muscle atrophy, and fatty infiltration. Fatty infiltration of the involved rotator cuff muscles has been identified as an important negative prognostic factor for the outcome after repair of massive r...

All–Extra-articular Repair of Anterosuperior Rotator Cuff Tears

Anterosuperior rotator cuff tears involve the subscapularis tendon, supraspinatus tendon, and rotator interval. The long head of the biceps is usually affected and unstable in these complex lesions. Arthroscopic repair of anterosuperior rotator cuff tears often consists of 2 different procedures. Whereas the subscapularis tendon is reconstructed under intra-articular visualization, the supraspi...
