Final answer:
The rotator cuff consists of muscles and tendons securing the shoulder joint; injuries or degeneration may lead to significant dysfunctions. A reverse shoulder replacement is a surgical option for severe cases, particularly in older patients with compromised rotator cuff functioning. It is typically managed by orthopedists with expertise in sports medicine.
Step-by-step explanation:
The rotator cuff is a group of muscles and tendons that surround the shoulder joint, providing support and enabling a wide range of motions. Injuries such as tears or degenerative conditions can significantly impair shoulder function. The supraspinatus, infraspinatus, teres minor, and subscapularis muscles make up the rotator cuff, and these muscles allow for movements and act as dynamic ligaments to hold the humerus within the glenoid cavity of the scapula.
When injuries or degeneration occur, this can lead to conditions like adhesive capsulitis or 'frozen shoulder.' In severe cases, particularly in older patients with disrupted blood supply and advanced arthritis, a reverse shoulder replacement may be indicated. This procedure involves replacing the damaged joint surfaces with a prosthesis, allowing for improved function and pain relief. Orthopedists, especially those with a subspecialty in sports medicine, often treat complex shoulder injuries, which can range from conservative treatments like exercise to surgical interventions such as shoulder replacement surgery.
