Rotator Cuff Injuries in Professional Athletes

The rotator cuff is four muscles — supraspinatus, infraspinatus, teres minor and subscapularis — whose tendons wrap the head of the humerus.

Injury progresses from inflammation and tendinopathy to partial tearing and, eventually, full-thickness tears that may retract.

Untreated large tears can lead to cuff-tear arthropathy, a specific pattern of shoulder arthritis.

• Overhead throwing repeatedly loads the cuff eccentrically during deceleration, which is when much of the damage occurs.
• Blocking, pushing and heavy pressing in training add compressive and shear stress.
• Playing through tendinopathy — common in professional sport — allows partial tears to progress.

Cuff degeneration from repetitive overhead work is one of the most widely recognized cumulative-trauma patterns in occupational medicine generally.

For pitchers and throwers, throwing volume across a career is a central part of the exposure narrative.

More on how repetitive-exposure claims work: Cumulative trauma explained.

• Weakness lifting the arm to shoulder height or above
• Night pain and difficulty sleeping on that side
• Difficulty with everyday tasks: reaching a seatbelt, washing hair, putting on a jacket
• Loss of throwing ability entirely

• Strength testing of each cuff muscle individually
• MRI or ultrasound to characterize tear size, location and retraction
• X-ray to assess arthritis and humeral head position
• Assessment of muscle atrophy and fatty infiltration on imaging, which affects repair options

• Records of shoulder injections, therapy and any surgical repair
• Pitching workload records or usage history where relevant
• Team injury reports, athletic training room logs and daily treatment notes
• Team physician and consulting specialist records, including imaging reports
• Surgical operative reports and post-operative rehabilitation notes
• Contracts, transaction history and roster or practice-squad records showing dates of employment
• Post-career medical records from primary care doctors, orthopedists and other specialists

Cuff tears with a documented career history of overhead work are commonly evaluated as cumulative injuries.

Where a specific event tore an already-degenerated cuff, aggravation principles may apply in some jurisdictions.

Future medical care for progression, including possible replacement surgery, may be part of the evaluation.

Rules differ by state and by sport. Eligibility factors and types of compensation cover the general framework.

• Physical therapy and cuff-specific strengthening
• Subacromial injections
• Arthroscopic or open repair, with revision options in some cases
• Reverse total shoulder arthroplasty for irreparable tears with arthritis

• Impairment is generally rated on strength and range-of-motion loss after maximum medical improvement.
• Large, retracted tears in older former athletes are sometimes deemed irreparable, which changes both treatment and rating.
• Overhead work restrictions can significantly limit post-career employment options.
