We conducted this cadaveric study to define a biome chanical rationale for rotator cuff function in several deficiency states. A dynamic shoulder testing appara tus was used to examine change in middle deltoid muscle force and humeral translation associated with simulated rotator cuff tendon paralyses and various sizes of rotator cuff tears. Supraspinatus paralysis re sulted in a significant increase (101 %) in the middle deltoid force required to initiate abduction. This in crease diminished…

Passive contribution of the rotator cuff to abduction and joint stability

Insight is provided into the potential biomechanical effect of repairing massive rotator cuff tears with a biological or synthetic “patch,” which is a new treatment for massive cuff tear.

Restoration of Shoulder Biomechanics According to Degree of Repair Completion in a Cadaveric Model of Massive Rotator Cuff Tear

If complete repair of massive cuff tear is not possible, posterior cuff (infraspinatus) repair is necessary to restore abnormal glenohumeral kinematics, and margin convergence anteriorly is recommended to decrease gap formation of the repaired tendon edge, which may provide a better biomechanical environment for healing.

It is suggested that repairing the infraspinatus back to its insertion site without repair of the suprasp inatus can improve shoulder function to a level similar to repairing both theinfraspInatus and suprasecapularis tendons.

The effect of infraspinatus disruption on glenohumeral torque and superior migration of the humeral head: a biomechanical study.

The entire infraspinatus contributes to abduction torque generation and stabilizes the humeral head against superior subluxation and contributes abduction force generation across the glenohumeral joint.

Biomechanics of massive rotator cuff tears: implications for treatment.

In the presence of a massive rotator cuff tear, stable glenohumeral abduction without excessive superior humeral head translation requires significantly higher forces in the remaining intact portion of the Rotator cuff.

Data supported the contention that certain rotator cuff tears in older individuals may be adequately treated with debridement and decompression, without repair.

Latissimus dorsi transfer for the treatment of massive tears of the rotator cuff. A preliminary report.

Transfer of the latissimus dorsi tendon from the humeral shaft to the superolateral humeral head provides a large, vascularized tendon that can be used to close a massive cuff defect and that exerts an external rotation and head-depressing moment that allow more effective action of the deltoid muscle.

This study shows that normal shoulder function is possible with a massive unrepaired tear of the rotator cuff, and in patients whose cuff tears satisfy anatomic and biomechanical criteria, the achievement of pain relief through arthroscopic debridement and decompression seems to be all that is necessary for normal pain-free function.

It is suggested that this technique is an acceptable alternative for repairing large or massive rotator cuff tears that have tendon substance loss and should not be used for smaller tears, for which more simple techniques are more adequate.

Rotator cuff tear. Diagnosis and treatment.

Early surgical repair of rotator cuff tears with a partial anterior acromionectomy is recommended as a means of minimizing a progression of symptoms and findings and a carefully supervised postoperative rehabilitation program is essential for optimum results.

Normal and abnormal mechanics of the glenohumeral joint in the horizontal plane.

In seven of the twelve patients who had anterior instability, abnormal mechanics were observed: anterior translation of the humeral head occurred, which indicates a significant disruption of the structures responsible for containing the humal head within the glenoid fossa.

The effect of capsular venting on glenohumeral laxity.

It was demonstrated that translational laxity of anatomic specimen shoulders was substantially increased when air was admitted into the capsule, and the principle of limited joint volume should be considered and tested when investigating glenohumeral stability.


It is suggested that when a case of rupture of the rotator cuff of the shoulder fails to respond to physiotherapy, operative repair should be undertaken.

The repair of chronic massive ruptures of the rotator cuff of the shoulder by use of a freeze-dried rotator cuff.

In sixteen patients with massive tears of the rotator cuff of the shoulder, bridging of the defect with a freeze-dried graft of a rotator cuff from a cadaver produced a satisfactory repair in all
