Abstract:
A revision rotator cuff repair is a technically challenging surgical procedure. This can be further complicated by the presence of poor quality of the cuff tissue, as well as a large greater tuberosity cyst, typically located at the rotator cuff footprint. This Technical Note discusses the surgical approach to deal with a revision rotator cuff tear with a large humeral head cyst. This described arthroscopic technique is performed in a single-stage procedure using a human dermal allograft (GraftJacket) for augmentation. This technique was specifically designed to (1) address the limited area for anchor placement, (2) use a bone graft, demineralized bone matrix, for repairing the bone cyst, and (3) optimize the biology for healing by augmenting the reconstruction with GraftJacket.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
Kinematic Equations for Rotation
For instance, imagine a point A on a rigid body engaged in circular motion. The translational velocity of this particular point can be calculated by taking the time derivatives of the displacement equation, which essentially measures the...
Rotation of Asymmetric Top
The relationship between the angular momentum of any rigid body and its angular velocity, both of which are vectors, involves the moment of inertia. The moment of inertia is a scalar quantity only for spherically symmetric...

Using our intuition, we can begin to see how rotational quantities such as angular displacement, angular velocity, angular acceleration, and time are related to one another. For example, if a flywheel...
