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

Rotator cuff tears can be classified into two main types based on their cause:
  1. 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.
  2. 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

Common symptoms of rotator cuff tears include:
  • 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

Diagnosis involves a combination of clinical evaluation and imaging studies:
  1. 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.
  2. 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

Treatment options depend on the severity of the tear, patient age, activity level, and overall health. They can be broadly categorized into non-surgical and surgical approaches:
 

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

Surgery may be necessary if non-surgical treatments fail to relieve symptoms or if the tear is severe. Surgical options include:
 
  1. Arthroscopic Repair: Minimally invasive surgery using small incisions and a camera to guide the repair of the torn tendon.
  2. Open Repair: A traditional approach involving a larger incision to directly access and repair the tear.
  3. Mini-Open Repair: Combines arthroscopy and a smaller open incision to repair the tendon.
  4. 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.
  5. Shoulder Replacement: In cases of massive rotator cuff tears associated with significant arthritis, a reverse total shoulder replacement may be performed.

Rehabilitation

Post-surgery rehabilitation is crucial for a successful recovery and typically involves:
  • 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

The prognosis for rotator cuff tears varies:
  • 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

Preventive measures include:
  • 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.
By understanding the causes, symptoms, and treatment options for rotator cuff tendon tears, individuals can seek timely medical attention and follow appropriate preventive strategies to maintain shoulder health. 

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:
    • Rest and Activity Modification: Avoiding activities that exacerbate symptoms.
    • Physical Therapy: Strengthening and stretching exercises to improve shoulder function.
    • Medications: NSAIDs for pain and inflammation management.
    • Steroid Injections: To reduce inflammation and pain.
  • Surgical:
    • Tenotomy: Releasing the damaged tendon, allowing it to retract and relieve pain. Often used for older, less active patients.
    • Tenodesis: Reattaching the tendon to the humerus, preserving biceps function. Preferred for younger, active patients or those requiring heavy lifting.

Rehabilitation

  • Post-Surgical Rehabilitation: Focuses on gradually restoring range of motion, strength, and function. This typically involves a structured physical therapy program.

Prognosis

  • Non-Surgical: Many individuals, especially older adults or those with lower activity demands, may achieve satisfactory results without surgery.
  • Surgical: Good outcomes are common with appropriate surgical intervention and rehabilitation, particularly in active individuals and athletes.

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

  1. 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.
  2. Bankart Lesions:
    • Location: Occur in the lower part of the labrum.
    • Description: Often associated with shoulder dislocations, leading to instability.
  3. 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.
  • Degenerative Changes: Wear and tear over time, often seen in older individuals.

Symptoms

  • Pain: Deep shoulder pain, especially with overhead activities or certain movements.
  • Instability: Feeling of the shoulder “catching,” “locking,” or “giving way.”
  • Decreased Range of Motion: Stiffness and difficulty moving the shoulder.
  • Weakness: Reduced strength, particularly with lifting or rotating the arm.
  • Clicking or Popping: Audible or palpable sensations during shoulder movement.

Diagnosis

  • Physical Examination: Includes specific tests like the O’Brien test, crank test, and Speed’s test to provoke symptoms.
  • Imaging: MRI arthrogram is the gold standard, providing detailed images of the labrum and other soft tissues.

Treatment

  1. Non-Surgical:
    • Rest and Activity Modification: Avoiding activities that exacerbate symptoms.
    • Physical Therapy: Strengthening and stabilizing the shoulder muscles, improving range of motion.
    • Medications: NSAIDs for pain and inflammation management.
    • Steroid Injections: To reduce inflammation and pain in some cases.
  2. Surgical:
    • Arthroscopic Surgery: Minimally invasive procedure to repair or debride the torn labrum.
    • Labral Repair: Stitching the torn labrum back to the glenoid.
    • Labral Debridement: Removing frayed or damaged portions of the labrum.
    • Capsulolabral Reconstruction: In severe cases, reconstructing both the labrum and the joint capsule.

Rehabilitation

  • Post-Surgical Rehabilitation: Essential for a successful recovery, focusing on gradually restoring range of motion, strength, and function. Typically involves a structured physical therapy program over several months.

Prognosis

  • Non-Surgical: Many patients achieve satisfactory outcomes with conservative management, especially if the tear is small or degenerative.
  • Surgical: Generally good outcomes with proper surgical repair and rehabilitation, particularly in active individuals and athletes.

Prevention

  • Strengthening Exercises: Focusing on the rotator cuff and scapular stabilizers to support the shoulder joint.
  • Proper Technique: Ensuring correct form during sports and physical activities to reduce stress on the shoulder.
  • Flexibility: Maintaining good shoulder flexibility through regular stretching exercises.

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

  • Immobilization: The shoulder is typically immobilized in a sling for a few weeks.
  • Rehabilitation:
    • Phase 1 (0-6 weeks): Gentle passive range-of-motion exercises while protecting the repair.
    • Phase 2 (6-12 weeks): Gradual introduction of active range-of-motion exercises and gentle strengthening.
    • Phase 3 (3-6 months): Progressive strengthening and return to normal activities.
    • Phase 4 (6-12 months): Full return to sports and high-demand activities, ensuring shoulder stability and strength.

Complications

  • Infection: As with any surgical procedure.
  • Nerve Injury: Potential injury to the musculocutaneous nerve or axillary nerve.
  • Nonunion or Malunion of the Graft: The bone graft may not heal properly.
  • Arthritis: Long-term risk of developing arthritis in the shoulder joint.
  • Loss of External Rotation: Possible decrease in the range of motion due to the altered anatomy.

Outcomes

The Latarjet procedure has a high success rate in stabilizing the shoulder and reducing the recurrence of dislocations, especially in patients with significant bone loss or previous failed surgeries. Proper rehabilitation and adherence to post-operative protocols are crucial for optimal outcomes.

Advantages

  • Enhanced Stability: The bony graft increases the depth of the glenoid socket.
  • Dynamic Stabilization: The transferred conjoint tendon acts as a dynamic sling during shoulder movements.

Considerations

  • Surgeon Experience: The procedure is technically demanding and should be performed by an experienced orthopedic surgeon.
  • Patient Selection: Ideal for patients with significant bone loss or previous surgical failures, but may not be necessary for all cases of shoulder instability.

Total Shoulder Replacement 

This surgery involves replacing damaged parts of the shoulder joint with artificial components. Total shoulder replacement is typically recommended for severe arthritis or massive, irreparable rotator cuff tears, aiming to alleviate pain and improve joint function.

Total shoulder replacement, also known as total shoulder arthroplasty (TSA), is a surgical procedure designed to relieve pain and restore function in patients with severe shoulder joint problems. Here’s a comprehensive overview:

Indications

  • Severe Arthritis: Osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis.
  • Severe Fractures: Complex fractures of the humeral head that cannot be repaired.
  • Avascular Necrosis: Death of bone tissue due to a lack of blood supply.
  • Failed Previous Surgeries: Such as failed shoulder reconstructions or partial shoulder replacements.

Anatomy

  • Humeral Head: The ball portion of the shoulder joint.
  • Glenoid: The socket portion of the shoulder joint.

Types of Shoulder Replacement

  1. Anatomic Total Shoulder Replacement:
    • Components: Replaces the humeral head with a metal ball and the glenoid with a plastic socket.
    • Indication: Typically used when the rotator cuff is intact or reparable.
  2. Reverse Total Shoulder Replacement:
    • Components: The normal ball-and-socket structure is reversed, with the ball attached to the glenoid and the socket attached to the humerus.
    • Indication: Used when the rotator cuff is severely damaged or irreparable.
    • Closure: The incision is closed in layers, and the arm is placed in a sling.

Postoperative Care

  • Immobilization: The shoulder is typically immobilized in a sling for a few weeks.
  • Rehabilitation:
    • Phase 1 (0-6 weeks): Focus on gentle passive range-of-motion exercises while protecting the repair.
    • Phase 2 (6-12 weeks): Gradual introduction of active range-of-motion exercises and gentle strengthening.

  • Longevity: Modern implants can last 15-20 years or more with appropriate use and care.

Advantages

  • Pain Relief: Provides substantial pain relief for patients with severe joint degeneration.
  • Restored Function: Improves shoulder function and quality of life.

Considerations

  • Surgeon Experience: The procedure is complex and should be performed by an experienced orthopedic surgeon.
  • Rehabilitation Commitment: Successful outcomes depend heavily on adherence to a structured rehabilitation program.

Reverse Total Shoulder Replacement 

Unlike traditional shoulder replacement, this surgery reverses the socket and the metal ball’s positions, making it ideal for patients with cuff tear arthropathy, a condition where the patient has both arthritis and a severe rotator cuff tear.

Reverse total shoulder replacement, also known as reverse total shoulder arthroplasty (RTSA), is a specialized type of shoulder replacement surgery used primarily for patients with complex shoulder conditions, particularly those involving severe rotator cuff damage. Here’s an in-depth look at the procedure:

Indications

  • Rotator Cuff Tear Arthropathy: Severe arthritis combined with irreparable rotator cuff tears.
  • Complex Fractures: Fractures of the proximal humerus that are not amenable to fixation.
  • Failed Previous Shoulder Surgeries: Including failed conventional shoulder replacements.
  • Chronic Shoulder Dislocations: Particularly with associated joint damage.
  • Avascular Necrosis: Advanced cases with concomitant rotator cuff insufficiency.

Anatomy and Biomechanics

  • Standard Anatomy: In a healthy shoulder, the rotator cuff muscles and tendons stabilize and move the joint.
  • Reverse Anatomy: In RTSA, the anatomy is altered. The normal ball-and-socket structure is reversed:
    • Glenoid (Socket): A metal ball (glenosphere) is attached to the glenoid.
    • Humerus (Ball): A plastic cup is placed on the upper end of the humerus.

Biomechanical Advantages

  • Deltoid Muscle Function: By reversing the joint configuration, the deltoid muscle can compensate for the deficient rotator cuff, allowing for improved shoulder elevation and function.

Postoperative Care

  • Immediate Post-Op: The arm is immobilized in a sling to protect the repair.
  • Pain Management: Medications and possibly nerve blocks.
  • Rehabilitation:
    • Phase 1 (0-6 weeks): Focus on passive range-of-motion exercises. The sling is worn most of the time.
    • Phase 2 (6-12 weeks): Gradual introduction of active range-of-motion exercises. Begin gentle strengthening.
    • Phase 3 (3-6 months): More intensive strengthening and functional exercises. Return to daily activities.
    • Phase 4 (6-12 months): Return to more strenuous activities, sports, or heavy lifting, if appropriate.

Complications

  • Infection: Risk of infection, potentially requiring antibiotics or further surgery.
  • Nerve Injury: Possible injury to surrounding nerves.
  • Dislocation: Though less common, there is a risk of the new joint dislocating.
  • Component Loosening: Over time, the components may loosen, necessitating revision surgery.
  • Scapular Notching: Erosion of the scapular bone due to contact with the humeral component.
  • Fracture: Risk of bone fractures during or after surgery.

Outcomes

  • Pain Relief: Significant reduction in shoulder pain.
  • Improved Function: Enhanced shoulder movement and strength, particularly in overhead activities.
  • Patient Satisfaction: High satisfaction rates due to improved quality of life and functional outcomes.

Advantages

  • Effective for Rotator Cuff Deficiency: Allows for functional shoulder use in the absence of a functional rotator cuff.
  • Improved Stability: Designed to reduce the risk of dislocation in cases with severe joint damage.

Considerations

  • Surgeon Experience: RTSA is complex and should be performed by a surgeon with experience in shoulder arthroplasty.
  • Rehabilitation Commitment: Successful outcomes rely heavily on adherence to a structured rehabilitation program.
  • Activity Modification: Patients may need to adjust their activities to prolong the life of the prosthesis.

Conclusion

Reverse total shoulder replacement is a valuable surgical option for patients with complex shoulder problems, particularly those with rotator cuff deficiency. By reversing the ball-and-socket configuration, RTSA allows the deltoid muscle to take over much of the shoulder’s function, providing pain relief and improved mobility. If considering this surgery, a detailed discussion with an orthopedic surgeon can provide personalized insights into the risks, benefits, and expected outcomes.

Shoulder Instability 

Shoulder instability treatment can range from physical therapy to surgery, depending on severity. Surgical options aim to repair or tighten the loose or torn ligaments that cause instability, providing long-term relief from recurrent dislocations and pain.

Shoulder instability occurs when the shoulder joint is unable to remain in its proper position, causing it to partially or completely dislocate. This condition can be due to a variety of factors, including traumatic injury, repetitive use, or congenital issues. Here’s a comprehensive overview of shoulder instability:

Anatomy

  • Shoulder Joint: A ball-and-socket joint where the humeral head (ball) fits into the glenoid cavity (socket) of the scapula (shoulder blade).
  • Ligaments and Labrum: Provide stability by holding the joint together. The labrum is a ring of cartilage that deepens the socket.
  • Rotator Cuff Muscles and Tendons: Surround and stabilize the shoulder joint.

Types of Shoulder Instability

  1. Traumatic Instability:
    • Dislocation: The humeral head completely comes out of the glenoid socket. Often due to an acute injury.
    • Subluxation: Partial dislocation where the humeral head slips out of the socket and then returns.
    • Bankart Lesion: Tear of the labrum due to dislocation.
    • Hill-Sachs Lesion: Compression fracture of the humeral head due to impact with the glenoid rim.
  2. Atraumatic Instability:
    • Multidirectional Instability (MDI): Shoulder instability in multiple directions (anterior, posterior, inferior) without a specific injury, often due to generalized ligamentous laxity.
  3. Congenital Instability:
    • Ehlers-Danlos Syndrome and other connective tissue disorders that cause loose ligaments and frequent dislocations.

Causes

  • Acute Trauma: Direct blow to the shoulder, fall on an outstretched arm, or forceful overhead motions.
  • Repetitive Overhead Activities: Sports like swimming, baseball, and tennis can overstress the shoulder.
  • Genetic Factors: Conditions that cause naturally loose or hypermobile joints.

Symptoms

Shoulder instability can significantly impact daily activities and athletic performance. Early diagnosis and appropriate treatment, whether non-surgical or surgical, are crucial for restoring shoulder function and preventing recurrent dislocations. Consulting with an orthopedic specialist can provide personalized management strategies and rehabilitation plans.

Pectoralis Major Tendon Repairs/Reconstruction 

This surgery repairs or reconstructs the pectoralis major tendon, often torn during weightlifting or sports. The procedure reattaches the tendon to its original location, restoring chest muscle function and appearance.

A tear in the pectoralis major tendon is a significant injury, often resulting from high-force activities, that can cause considerable pain and functional impairment. Here’s an in-depth look at this condition:

Anatomy

  • Pectoralis Major Muscle: A large, powerful muscle located in the chest. It has two heads:
    • Clavicular Head: Originates from the clavicle.
    • Sternal Head: Originates from the sternum and the cartilage of the first six ribs.
  • Tendon Insertion: Both heads converge and attach to the lateral lip of the bicipital groove of the humerus (upper arm bone).

Types of Tears

  • Partial Tears: Involves only a portion of the tendon.
  • Complete Tears: The tendon is fully detached from the humerus.
  • Musculotendinous Junction Tears: Occur where the muscle transitions to tendon.
  • Tendinous Tears: Occur at the tendon attachment to the bone.

Causes

  • Acute Trauma: Sudden, forceful impact or heavy lifting, especially during activities like bench pressing or other weightlifting exercises.
  • Repetitive Stress: Overuse in sports such as bodybuilding, wrestling, or activities involving repetitive heavy pushing motions.

  • Alleviates Pain: Reduces pain associated with AC joint instability and dislocation.

Considerations

  • Surgeon Experience: The procedure should be performed by an experienced orthopedic surgeon specializing in shoulder injuries.
  • Rehabilitation Commitment: Successful outcomes rely on adherence to a structured rehabilitation program.
  • Activity Modification: Patients may need to adjust activities during the recovery period to avoid stress on the healing joint.

Conclusion

AC joint reconstruction is a valuable surgical option for patients with severe or chronic AC joint instability, dislocation, or pain that has not responded to conservative treatment. By stabilizing the joint and restoring its normal anatomy, this procedure can significantly improve shoulder function and quality of life. If you are considering AC joint reconstruction, a detailed discussion with an orthopedic specialist can provide personalized insights into the risks, benefits, and expected outcomes based on your specific condition and lifestyle.

Adhesive Capsulitis (Frozen Shoulder) 

Treatment for adhesive capsulitis, commonly known as frozen shoulder, involves therapies to restore mobility and decrease pain. This may include physical therapy, medication, and in severe cases, surgery to loosen the joint capsule.

Shoulder Dislocations 

Treatment for shoulder dislocations typically involves repositioning the dislocated bone, followed by rehabilitation to restore strength and prevent recurrence. In cases of recurrent dislocations, surgery may be necessary to repair or tighten the ligaments that stabilize the shoulder.
