Labral tears generally occur from occur from overhead sports or an injury with the arm extended overhead. Labral tears do not heal themselves because of their limited blood supply and the movement and instability of the torn portion; therefore, they typically require surgery. This tear may take the form of degenerative fraying, a split in the labrum, or a complete separation of the labrum off the bony glenoid. SLAP tears will often involve damage to the biceps tendon attachment. Superior labral tears can be difficult to see on MRI and are discovered only during arthroscopic surgery.
Because no two people and no two injuries are alike, Dr. Chudik uses his expertise to develop and provide individualized care and recovery plans for his patients. This customized attention explains why patients travel to have Dr. Chudik care for their shoulder conditions and injuries.
To ensure his patients can return to sports and activities safely, Dr. Chudik researched and developed a return to sport functional test protocol that provides objective measures for both the athlete and Dr. Chudik to know when it is safe to return, as well as what else needs to be done if the athlete fails to pass the exam.
The labrum is a fibrocartilaginous tissue that circles the peripheral rim of the glenoid (socket of the shoulder). The labrum functions as the attachment site of the shoulder capsule and ligaments that run between the humeral head (ball) and glenoid (socket) of the shoulder to provide stability. The long head of the biceps tendon also attaches to the superior (upper) bony glenoid (socket) by its attachment through the superior (upper) labrum. Injury to the superior labrum is referred to as a SLAP lesion (tear), which stands for Superior Labrum, Anterior to Posterior (front to back). This tear may take the form of degenerative (wear and tear) fraying, a split in the labrum, or a complete separation of the labrum off the bony glenoid (socket), with or without damage to the biceps tendon attachment. Superior labral separations also result in some lesser amounts of shoulder instability. Superior labral tears are sometimes difficult to see on MRI and are sometimes only found during arthroscopic surgery (see arthroscopic pictures below).
Many labral tears are not symptomatic and do not need surgery, especially if they are degenerative or if the patient does not perform strenuous repetitive overhead activities. Labral tears do not heal by themselves because of their limited blood supply and the instability (continued motion) of the torn portion. Therefore, if they are symptomatic, they typically require surgery. Physical exam findings are not sufficiently specific to reliably make the diagnosis of a labral tear. MRI and MRI arthrograms (MRI following dye injection into the shoulder) are limited and can fail to show clinically significant labral tears. Thus, after an acute shoulder injury with a history and physical exam findings consistent with a SLAP tear, conservative treatment of physical therapy is often needed to determine if the injury will improve without surgery. After four to six weeks of proper shoulder therapy, the majority of milder sprains or strains (that do not need surgery) will improve and actual SLAP tears will continue to cause symptoms and produce pain with specific physical exam tests. Following surgical treatment, SLAP tears often heal and symptoms improve dramatically.
The shoulder has a remarkable range of motion, making it one of your body’s most mobile and important joints. Whether you are throwing a baseball, working overhead, or performing everyday tasks of reaching and carrying, your shoulder motion is critical to this high level of function. Unfortunately, this increased mobility and structural complexity makes your shoulders susceptible to injuries that can be quite limiting and disabling.
Scapula (shoulder blade)
Clavicle (collar bone)
Humerus (upper arm bone)
Glenohumeral joint (shoulder joint)
Acromioclavicular joint (shoulder blade-collar bone joint)
Sternoclavicular joint (sternum-collar bone joint)
Scapulothoracic articulation (shoulder blade-chest connection)
The shoulder has a labrum or thickening of firm soft tissue attached to the rim of the glenoid (socket). It deepens the socket to increase stability, bears load and is the attachment point for ligaments that run between the upper arm bone and the bony glenoid (socket). Ligaments are strong soft-tissue bands that connect bones at a joint and provide stability and proper limits to motion. The labrum and ligaments may be torn if forces cause the humeral head (ball) to abruptly shift from the glenoid (socket) such as during a shoulder dislocation. Shoulder ligaments get their names from the bones to which they connect and include the superior glenohumeral ligament (SGHL), middle glenohumeral ligament (MGHL), and the inferior glenohumeral ligament (IGHL) with important anterior and posterior bands. Other important ligaments in the shoulder include the acromioclavicular, coracoclavicular, and sternoclavicular ligaments.
The joint surfaces of the shoulder are covered with a thin, but durable, layer of cartilage over the ends of the humeral head (ball) and glenoid (socket) that allows the shoulder surfaces to articulate, and move smoothly—almost frictionless and painlessly along each other. The cartilage lacks a blood supply. It gets nutrition from the joint fluid. Without a blood supply and because of its relatively less active cellular makeup, cartilage does not maintain or repair itself. The cartilage is extremely durable, but in time with “wear and tear” or following injury, it breaks down, fails, and leads to cartilage damage and eventually symptomatic (pain, stiffness, swelling) arthritis (failure of this protective joint surface).
The shoulder has several muscles that help it move with proper coordination and strength to accomplish tasks ranging from simple reaching to high-level overhead athletic maneuvers. Muscles are like loaded active springs. They attach to bones across joints by different-shaped rope- or band-like tendons to exert their action and cause movement. The rotator cuff is a deep, core group of four muscles. They keep the humeral head (ball) centered on the glenoid (socket) while the pectoralis major, deltoid, and latissimus dorsi (the big muscle movers of the arm) create pulling and pushing forces that would otherwise shift the humeral head out of the glenoid (socket). Even with simply reaching out and away from your body the rotator cuff must generate forces equal to almost 80 percent of your body weight to keep the humeral head centered in the glenoid. Still, greater forces are needed during overhead throwing or strenuous lifting movements. These tremendous forces can cause tears in the tendon portion of the rotator cuff and result in pain and arm/shoulder limitations. The long head of the biceps muscle that attaches to the top of the glenoid through the superior (top) labrum can also be injured and cause pain. Additionally, muscles control the shoulder joint’s scapula (shoulder blade) or base, which can be affected by injury and overuse producing shoulder pain and limitations.
An inquisitive nature was the impetus for Dr. Steven Chudik’s career as a fellowship-trained and board-certified orthopaedic surgeon, sports medicine physician and arthroscopic pioneer for shoulder injuries. It also led him to design and patent special arthroscopic surgical procedures and instruments and create the Orthopaedic Surgery and Sports Medicine Teaching and Research Foundation (OTRF). Through OTRF, Dr. Chudik conducts unbiased orthopaedic research and provides up-to-date medical information to help prevent sports injuries. He also shares his expertise and passion mentoring medical students in an honors research program and serve as a consultant and advisor for other orthopaedic physicians and industry research.
Dr. Steven Chudik continually innovates to create new technology, and surgical techniques and improve patient care. He also collaborates worldwide with other leaders in the orthopaedic technology industry. Surgeries provide Dr. Chudik with an endless source of ideas to create new, safer, less invasive, and more effective surgical procedures, surgical instruments, and implants. Several of his shoulder patents are the direct result of these pioneering endeavors.
