The rotator cuff is a group of muscles and their tendons that act to stabilize the human shoulder and allow for its extensive range of motion. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are:
Shoulder problems including pain, are one of the more common reasons for physician visits for musculoskeletal symptoms. The shoulder is the most movable joint in the body. However, it is an unstable joint because of the range of motion allowed. This instability increases the likelihood of joint injury, often leading to a degenerative process in which tissues break down and no longer function well.
The human shoulder is made up of three bones: the clavicle (collarbone), the scapula, and the humerus as well as associated muscles, ligaments and tendons.
Orthopedic surgery or orthopedics is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders.
Rotator cuff tendinopathy is a process of senescence. The pathophysiology is mucoid degeneration. Most people develop rotator cuff tendinopathy within their lifetime.
Adhesive capsulitis, also known as frozen shoulder, is a condition associated with shoulder pain and stiffness. It is a common shoulder ailment that is marked by pain and a loss of range of motion, particularly in external rotation. There is a loss of the ability to move the shoulder, both voluntarily and by others, in multiple directions. The shoulder itself, however, does not generally hurt significantly when touched. Muscle loss around the shoulder may also occur. Onset is gradual over weeks to months. Complications can include fracture of the humerus or biceps tendon rupture.
Joint replacement is a procedure of orthopedic surgery known also as arthroplasty, in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. Joint replacement surgery is often indicated from various joint diseases, including osteoarthritis and rheumatoid arthritis.
A SLAP tear or SLAP lesion is an injury to the glenoid labrum. SLAP is an acronym for "superior labral tear from anterior to posterior".
Cold compression therapy, also known as hilotherapy, combines two of the principles of rest, ice, compression, elevation to reduce pain and swelling from a sports or activity injury to soft tissues and is recommended by orthopedic surgeons following surgery. The therapy is especially useful for sprains, strains, pulled muscles and pulled ligaments.
Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon from the overlying coraco-acromial ligament, acromion, and coracoid and from the deep surface of the deltoid muscle. The subacromial bursa helps the motion of the supraspinatus tendon of the rotator cuff in activities such as overhead work.
Shoulder replacement is a surgical procedure in which all or part of the glenohumeral joint is replaced by a prosthetic implant. Such joint replacement surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage.
Shoulder impingement syndrome is a syndrome involving tendonitis of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion. It is particularly associated with tendonitis of the supraspinatus muscle. This can result in pain, weakness, and loss of movement at the shoulder.
Platelet-rich plasma (PRP), also known as autologous conditioned plasma, is a concentrate of platelet-rich plasma protein derived from whole blood, centrifuged to remove red blood cells. Though promoted to treat an array of medical problems, evidence for benefit is mixed as of 2020, with some evidence for use in certain conditions and against use in other conditions.
Michael J. Bronson, M.D., is an American orthopaedic surgeon, Chairman of the Department of Orthopedic Surgery, Mount Sinai West and Mount Sinai Morningside, and Chief of Joint Replacement Surgery at the Icahn School of Medicine at Mount Sinai in New York, and the author of extensive advances in the development of minimally invasive surgical instruments to advance unicondylar partial knee replacement, including the Vision Total Hip System, a widely used hip replacement system that avoids the use of cement.
Joseph D. Zuckerman is an American orthopedic surgeon specializing in shoulder, hip and knee replacement surgery.
Bryan L. Reuss is an American orthopaedic surgeon. He received a Bachelor of Arts Degree in Biology with distinction from the University of Kansas in 1996 and graduated with honors with an M.D. from the University of Nebraska College of Medicine in 2000. From 2000 to 2005, Dr. Reuss was an Orthopaedic Surgery Resident Physician in the Orlando Regional Healthcare System. In 2004-2005 he was awarded the "Resident of the Year" for Orlando Regional Healthcare chosen from all the hospital system's Resident Doctors. He completed an Orthopaedic Fellowship at the University of Cincinnati/Wellington Orthopaedics and Sports Medicine Fellowship in 2006. In 2010, Dr. Reuss was awarded the Sports Medicine Person of the Year from the Athletic Trainers Association of Florida.
Postarthroscopic glenohumeral chondrolysis (PAGCL) is a rare complication of arthroscopic surgery and involves chondrolysis wherein the articular cartilage of the shoulder undergoes rapid, degenerative changes shortly after arthroscopic surgery.
Reverse shoulder replacement is a type of shoulder replacement in which the normal ball and socket relationship of glenohumeral joint is reversed, creating a more stable joint with a fixed fulcrum. This form of shoulder replacement is utilized in situations in which conventional shoulder replacement surgery would lead to poor outcomes and high failure rates.
A biceps tendon rupture or bicep tear is a complete or partial rupture of a tendon of the biceps brachii muscle. It can affect any of the three biceps brachii tendons - the proximal tendon of the short head of the muscle belly, the proximal tendon of the long head of the muscle belly, or the distal tendon. The characteristic finding of a biceps tendon rupture is the Popeye sign. Patients often report an audible pop at the time of injury as well as pain, bruising, and swelling. Provocative physical exam maneuvers to assess for a rupture include Ludington's test, Hook test, and the Ruland biceps squeeze test. Treatment and prognosis are highly dependent on the site of the injury described in further detail below.
The Eden-Lange procedure is an orthopedic procedure to alleviate the symptoms of trapezius palsy when more conservative measures, such as spontaneous resolution and surgical nerve repair are not promising. The rhomboid major, rhomboid minor, and levator scapulae muscles are transferred laterally along the scapula to replace the functions of the lower, middle, and upper fibers of the trapezius, respectively. The transferred muscles hold the scapula in a more medial and upwardly rotated position, without winging.
