A rotator cuff tear is a common injury involving the shoulder's rotator cuff muscles or tendons. The rotator cuff is a group of four muscles and their associated tendons that stabilize the shoulder and allow for its wide range of motion.
Anatomy[edit]
The rotator cuff consists of the supraspinatus, infraspinatus, teres minor, and subscapularis muscles. These muscles originate from the scapula and attach to the humerus, forming a cuff around the shoulder joint.
Types[edit]
Rotator cuff tears can be classified into two main types:
- Partial tear: This type of tear damages the soft tissue but does not completely sever it.
- Full-thickness tear: This type of tear is more severe and involves a complete rupture of the tendon.
Causes[edit]
Rotator cuff tears can result from:
- Acute injury: Sudden trauma, such as falling on an outstretched arm.
- Chronic overuse: Repetitive overhead activities, common in sports like baseball and tennis, or occupations such as painting and carpentry.
Risk Factors[edit]
Several factors can increase the risk of developing a rotator cuff tear:
- Age: The risk increases with age due to wear and tear.
- Repetitive overhead activities: Sports and jobs that involve frequent overhead motions.
- Trauma: Direct injury to the shoulder.
Symptoms[edit]
Common symptoms of a rotator cuff tear include:
- Shoulder pain, especially at night
- Weakness in the shoulder
- Limited range of motion
Diagnosis[edit]
Diagnosis typically involves:
- Physical examination: Assessing pain, range of motion, and strength.
- Imaging studies: X-rays, ultrasound, or MRI to visualize the tear.
Differential Diagnosis[edit]
Conditions that may present similarly include:
Treatment[edit]
Treatment options vary based on the severity of the tear:
- Non-surgical: Physical therapy, medications such as NSAIDs, and corticosteroid injections.
- Surgical: Arthroscopic surgery or open repair for severe cases.
Prevention[edit]
Preventive measures include:
- Strengthening exercises: Focused on the rotator cuff and shoulder muscles.
- Proper technique: In sports and occupational activities to avoid overuse injuries.
Complications[edit]
Potential complications from a rotator cuff tear include:
- Frozen shoulder (adhesive capsulitis)
- Arthritis in the shoulder joint
