Animal Experiments Using Rotator Cuff

Rotator cuff tears: what have we learned from animal models?

Rotator cuff tendon tears are among the most common soft tissue injuries that occur at the shoulder. Despite advancements in surgical repair techniques, rotator cuff repairs experience a high rate of failure. The common occurrence of tears and the frequency of re-tears require a further understanding of the mechanisms associated with injuries, healing, and regeneration of the rotator cuff. This...

Characteristics of Rotator Cuff Repairs Revised to Shoulder Arthroplasty

Background: Successful repair of a torn rotator cuff may prevent progression to rotator cuff arthropathy. However,previous studies have shown a substantial rate of failure after rotator cuff repair and characteristics of surgicallyrepaired rotator cuffs that go on to shoulder arthroplasty have not been fully elucidated. The purpose of this study wasto determine the patient cha...

Massive rotator cuff tear.

Anthony A. Romeo, MD, Department of Orthopaedic Surgery, Rush University Medical Center, Chicago, Illinois. B C A A 72-year-old woman presents with chronic shoulder pain subsequent to a fall that has not responded to conservative treatment. She tells you that she “wants it fixed.” T2-weighted coronal (A) and sagittal (B) and T1-weighted sagittal (C) magnetic resonance images are provided. What ...

Rotator Cuff Biomechanics

The aim of this presentation is to discuss the current literature and opinions on the biomechanics of the rotator cuff and relate this to the clinical relevance in rotator cuff tears. I intend to cover: Relate Biomechanics to Clinical Relevance 1. Cuff Mechanics 2. Tendon Anatomy – layers, microanatomy, blood supply 3. Pathomechanics of cuff tears The shoulder complex comprises 30 muscles. Thes...
