Shoulder
Rotator Cuff Tendon Tears
Rotator cuff tendon tears are common injuries that affect the shoulder, leading to pain, weakness, and reduced range of motion. The rotator cuff is a group of four muscles and their associated tendons that stabilize the shoulder and allow for a wide range of shoulder movements. These muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis.
Causes
- Acute Tears: These occur suddenly, often due to a traumatic event such as:
- Falling on an outstretched arm.
- Lifting something too heavy with a jerking motion.
- Sudden, forceful movements.
- Chronic Tears: These develop gradually over time due to:
- Degeneration: Wear and tear associated with aging.
- Repetitive Stress: Repeated overhead activities or heavy lifting.
- Poor Blood Supply: Reduced blood flow to the rotator cuff tendons, impairing their ability to heal.
- Bone Spurs: Bony growths that can rub against the tendons, causing damage.
Symptoms
- Pain: Often located on the front and side of the shoulder, worsening with overhead activity or at night.
- Weakness: Difficulty lifting or rotating the arm.
- Reduced Range of Motion: Inability to fully lift the arm or perform certain movements.
- Clicking or Popping: Sensation or sound during shoulder movement.
Diagnosis
- Medical History and Physical Examination:
- Discuss symptoms, medical history, and activity levels.
- Perform physical tests to assess shoulder strength, range of motion, and specific maneuvers to pinpoint the source of pain.
- Imaging Studies:
- X-rays: To rule out bone-related issues and check for bone spurs.
- MRI (Magnetic Resonance Imaging): Provides detailed images of soft tissues, including the rotator cuff tendons, to identify the extent of the tear.
- Ultrasound: Another imaging option to evaluate the tendons dynamically during movement.
Treatment
Non-Surgical Treatment
- Rest: Avoid activities that exacerbate the pain.
- Ice and Heat Therapy: Apply ice to reduce inflammation and heat to relieve muscle tension.
- Physical Therapy: Exercises to improve shoulder strength and flexibility.
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
- Steroid Injections: Corticosteroid injections to reduce severe pain and inflammation temporarily.
Surgical Treatment
- Arthroscopic Repair: Minimally invasive surgery using small incisions and a camera to guide the repair of the torn tendon.
- Open Repair: A traditional approach involving a larger incision to directly access and repair the tear.
- Mini-Open Repair: Combines arthroscopy and a smaller open incision to repair the tendon.
- Tendon Transfer: Used when the torn tendon is too damaged to be repaired, involving the transfer of a nearby tendon to take over the function.
- Shoulder Replacement: In cases of massive rotator cuff tears associated with significant arthritis, a reverse total shoulder replacement may be performed.
Rehabilitation
- Immobilization: Wearing a sling to protect the repair initially.
- Physical Therapy: Gradual exercises to restore range of motion, followed by strengthening exercises.
- Gradual Return to Activity: Slowly resuming normal activities and avoiding heavy lifting or overhead movements until fully healed.
Prognosis
- Small, Acute Tears: Often have a good prognosis with appropriate treatment.
- Large, Chronic Tears: May require more extensive treatment and have a longer recovery period, but many patients still achieve significant improvement.
Prevention
- Regular Exercise: Strengthening shoulder muscles and maintaining flexibility.
- Proper Technique: Using correct techniques during sports and activities.
- Ergonomics: Adjusting workstations and practices to reduce strain on the shoulders.
- Avoiding Overuse: Taking breaks and avoiding repetitive shoulder movements.
Biceps Repair/Tenodesis
Biceps repair or tenodesis is performed to fix tears or lesions in the biceps tendon at the shoulder. This procedure can either reattach the torn tendon or release and re-anchor it, relieving pain and restoring normal arm function. It’s particularly effective for patients with bicep tendonitis or tears.
Long head biceps tears, also known as tears of the long head of the biceps tendon (LHBT), can significantly affect shoulder function and cause considerable discomfort. Here’s a comprehensive overview:
Anatomy
- Biceps Brachii: The biceps muscle has two tendons at the shoulder, the long head and the short head.
- Long Head Tendon: This tendon originates from the supraglenoid tubercle of the scapula and runs through the shoulder joint, traversing the bicipital groove of the humerus.
Types of Tears
- Partial Tears: Incomplete tears where only a portion of the tendon is damaged.
- Complete Tears: The tendon is completely severed from its attachment point.
Causes
- Acute Injury: Resulting from a sudden traumatic event, such as lifting something heavy or a fall.
- Chronic Overuse: Repeated overhead activities, common in sports like baseball, swimming, or tennis.
- Degenerative Changes: Age-related wear and tear leading to tendon fraying and eventual rupture.
- Shoulder Impingement: The tendon becomes pinched between the bones or soft tissues of the shoulder, leading to inflammation and tearing.
Symptoms
- Pain: Sudden, sharp pain in the front of the shoulder, often accompanied by a popping sound in acute cases.
- Weakness: Decreased strength in shoulder and elbow flexion.
- Deformity: The “Popeye” sign, a bulge in the upper arm due to the retracted biceps muscle.
- Bruising: Swelling and bruising in the shoulder or upper arm area.
Diagnosis
- Physical Examination: Assessing for tenderness, deformity, and range of motion.
- Imaging: MRI or ultrasound to visualize the extent of the tear and rule out other shoulder pathology.
Treatment
- Non-Surgical:

Prevention
- Strengthening Exercises: Targeting shoulder stability and biceps strength.
- Proper Technique: In sports and lifting activities to avoid undue stress on the tendon.
- Regular Stretching: To maintain flexibility and reduce injury risk.
Labral Repairs (Anterior, Posterior, SLAP Tears)
Labral repairs target the labrum, a cuff of cartilage in the shoulder joint. This surgery is effective for fixing tears in the labrum, including anterior, posterior, and SLAP (Superior Labrum Anterior and Posterior) tears, commonly caused by trauma or overuse.
Shoulder labral tears involve damage to the labrum, a ring of cartilage that surrounds the socket of the shoulder joint (glenoid). The labrum helps stabilize the shoulder by deepening the socket and providing attachment points for ligaments and tendons. Here’s a comprehensive look at shoulder labral tears:
Anatomy
- Labrum: A fibrocartilaginous structure that forms a cup-like rim around the glenoid, providing stability and cushioning for the shoulder joint.
- Glenohumeral Joint: The ball-and-socket joint formed by the humerus (upper arm bone) and the glenoid cavity of the scapula (shoulder blade).
Types of Labral Tears
- SLAP Tears (Superior Labrum Anterior and Posterior):
- Location: Occur at the top of the labrum where the biceps tendon attaches.
- Description: The tear runs from the front (anterior) to the back (posterior) of the labrum.
- Bankart Lesions:
- Location: Occur in the lower part of the labrum.
- Description: Often associated with shoulder dislocations, leading to instability.
- Posterior Labral Tears:
- Location: Occur at the back of the labrum.
- Description: Less common but can result from trauma or repetitive stress.
Causes
- Acute Injury: Trauma such as falls, direct blows, or shoulder dislocations.
- Repetitive Overhead Activities: Common in athletes who engage in sports like baseball, tennis, swimming, and weightlifting.

Laterjet Procedure
The Latarjet procedure is a surgical intervention for chronic shoulder instability, especially in cases of bone loss or recurrent dislocations. It involves transferring a small piece of bone with an attached tendon to the shoulder joint, thereby improving stability.
The Latarjet procedure, also known as the Bristow-Latarjet procedure, is a surgical technique used to treat recurrent shoulder dislocations, especially in cases where there is significant bone loss in the glenoid (socket) or Hill-Sachs lesions (compression fractures of the humeral head). Here’s a comprehensive overview of the procedure:
Indications
- Recurrent Shoulder Dislocations: Particularly when other soft tissue repairs have failed.
- Glenoid Bone Loss: Significant bone loss on the anterior (front) part of the glenoid.
- Engaging Hill-Sachs Lesion: A defect on the humeral head that engages with the glenoid rim, contributing to instability.
- Failed Previous Surgeries: When previous stabilization procedures (like Bankart repairs) have not succeeded.
Anatomy Involved
- Coracoid Process: A bony projection on the scapula (shoulder blade) used in the Latarjet procedure.
- Subscapularis Muscle: The tendon of this muscle is split during the procedure to access the glenoid.
- Glenoid: The socket of the shoulder joint.
Postoperative Care
