Tennis shoulder

J D Priest, D A Nagel

    The American Journal of Sports Medicine
    |January 1, 1976

    Summary
    This summary is machine-generated.

    Skilled athletes with overhand motions develop shoulder depression due to muscle stretching and hypertrophy. This condition causes rotator cuff symptoms and may lead to thoracic outlet syndrome or mimic scoliosis.

    Area of Science:

    • Sports Medicine
    • Orthopedics
    • Biomechanics

    Background:

    • Overhand athletic activities can lead to specific musculoskeletal adaptations.
    • Repetitive overhead motions are common in sports like tennis.
    • Understanding these adaptations is crucial for injury prevention and performance.

    Purpose of the Study:

    • To identify and describe shoulder depression in athletes.
    • To investigate the causes and consequences of shoulder depression.
    • To explore the relationship between shoulder depression and rotator cuff issues.

    Main Methods:

    • Observational study of skilled tennis players and other athletes.
    • Analysis of biomechanical factors contributing to shoulder deformity.
    • Clinical assessment of shoulder pain and range of motion.

    Main Results:

    • A distinct shoulder depression deformity was observed in athletes using overhand motions.
    • The deformity is linked to stretching of shoulder elevators and extremity hypertrophy.
    • Anterior rotator cuff symptoms, particularly during arm abduction, were prevalent.

    Conclusions:

    • Shoulder depression in athletes is associated with specific muscle imbalances.
    • This condition can lead to impingement of the rotator cuff.
    • Shoulder droop may contribute to thoracic outlet syndrome and mimic scoliosis.
