Sports Medicine

Sports Medicine, also known as sports and exercise medicine (SEM), is a branch of medicine that deals with the treatment and prevention of sports and exercise-related injuries and improving fitness and performance. The main objective of sports medicine is to help individuals engage in sports and exercise safely and effectively to accomplish their training goals.

What are Sports Injuries?

Sports injuries are injuries sustained while playing indoor or outdoor sports such as football, basketball, hockey, baseball, and tennis, or while exercising. Sports injuries can result from sports accidents, inadequate training, improper use of protective devices, or insufficient stretching or warm-up exercises.

Shoulder Injuries in Overhead Athletes

An overhead athlete is at increased risk of injury due to the mechanism associated with rapid shoulder elevation, external rotation, and abduction. An overhead throwing motion is an intricate and skillful movement that presents a special challenge of needing the glenohumeral joint to surpass its physiologic limits during overhead sports activities.

Athletes involved in overhead sports such as baseball, American football, tennis, volleyball, swimming, and other repetitive throwing sports apply immense force across their shoulders during hitting and throwing actions and are at increased risk of developing overhead shoulder injuries. An overhead injury may occur due to improper techniques, training errors, shoulder instability, shoulder imbalance, and overuse of muscles surrounding the shoulder.

Causes of Overhead Athlete’s Shoulder Injuries
‍Most problems in the shoulder involve ligaments, muscles, tendons, and joints. Some of the common causes that can be attributed to overhead athlete’s shoulder injuries include:Inflammation of the jointsTorn cartilage or torn rotator cuffInflammation of the tendons or rotator cuff tendinitisBursitis or swelling of the bursa sacsFractures and dislocationsStiffening of the ligaments, muscles, and tendonsShoulder instability (a condition where a shoulder joint is forced out or moves out of its normal position) Shoulder impingement (inflammation from repetitive shoulder activities)

Symptoms of Overhead Athlete’s Shoulder Injuries
Some of the common symptoms of overhead athlete’s shoulder injuries include:
‍
- Persistent pain and tenderness
- Referred or radiating pain
- Loss of range of motion
- Pain with overhead action
‍
Reduction in throwing velocityTightness of the chest musclesSnapping or popping sensationWeaknessScapular winging (a painful condition of the shoulder blades)

Types of Overhead Athlete’s Shoulder Injuries

Athletes in sports such as baseball, tennis, and American football are more susceptible to overhead athlete’s shoulder injuries that include:

‍SLAP Tears: In a slap injury, the superior part of the shoulder labrum is injured. The labrum is a rim of tough fibrous tissue that stabilizes the shoulder joint. This type of injury commonly occurs in sports with overhead motions such as baseball.

‍Tendon Tears and Biceps Tendinitis: Repetitive throwing movement leads to irritation and inflammation of the biceps tendon known as biceps tendinitis. Damage to the tendon may also result in a tear leading to a torn biceps tendon.

‍Rotator Cuff Tears and Tendinitis: Overuse of the rotator cuff muscles or tendons results in a rotator cuff tear and tendinitis. This is most commonly observed in baseball throwers due to repeated high-speed throwing activity that adds significant stress on the ligaments and rotator cuff tendons of the shoulder.

‍Impingement: During an overhand throwing action as in baseball, the rotator cuff tendons at the back of the shoulder get pinched between the humeral head and the glenoid socket. This is known as internal impingement that leads to partial tearing of the rotator cuff tendon and may also damage the shoulder labrum.

‍Instability: Shoulder instability happens when the humeral head slips out of the shoulder socket resulting in dislocation. This is seen in throwers where the instability occurs due to repetitive throwing motions that stretch the ligaments causing increased laxity (looseness).

‍Scapular Rotation Dysfunction: This type of injury is mostly noted in throwers where the repeated use of scapular muscles leads to changes in the muscles that affect the position of the scapula resulting in drooping of the affected shoulder.

‍Glenohumeral Internal Rotation Deficit (GIRD): In this type of injury, soft tissues in the back of the shoulder tighten leading to loss of internal rotation due to high-speed repetitive throwing action noted in throwers. This puts throwers at a greater risk of rotator cuff and labral tears.

Diagnosis of Overhead Athlete’s Shoulder Injuries
Your doctor will review your symptoms and medical history and perform a physical examination to check for range of motion, stability, and strength of your shoulder. If necessary, your doctor will order certain imaging tests such as X-rays, MRI, CT scan, or ultrasound to confirm the source of pain and narrow down any associated problems.

Treatment for Overhead Athlete’s Shoulder Injuries
Treatments for overhead athlete’s shoulder injuries include both surgical as well as non-surgical options. Your doctor will decide the best option for you based on the condition of your shoulder.

The non-surgical treatment options may include:

‍Ice: Application of ice packs on the shoulder to decrease swelling and pain

‍Activity Modification:  Avoiding activities that trigger symptoms and changing your lifestyle

‍Physical Therapy:  Regular exercise regimen to improve range of motion and strengthen shoulder muscles

‍Anti-inflammatory Medication:  Meds like naproxen and ibuprofen can relieve inflammation and pain.

‍Cortisone Injection: If physical therapy, medications, rest, and activity modification do not yield the desired results, then a cortisone injection may be helpful. Cortisone is a very effective anti-inflammatory medicine for bursitis and long-term pain reliever for tears and structural damage.

The surgical treatment options may include:

‍Arthroscopy: Most throwing injuries can be treated with arthroscopic surgery. Your doctor will be able to repair damage to soft tissues, such as ligaments, labrum, or rotator cuff tears by using this technique. Arthroscopy is a minimally invasive surgical procedure that involves making small keyhole incisions to pass a fiberoptic tube with a tiny camera called an arthroscope and miniature instruments into the shoulder joint. The camera displays pictures of the affected region on a television screen and the doctor uses these images to carry out the surgery.
