Cuff-tear arthropathy.

C S Neer, E V Craig, H Fukuda

    The Journal of Bone and Joint Surgery. American Volume
    |December 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Cuff-tear arthropathy, a severe shoulder condition, develops after massive rotator cuff tears due to joint instability and cartilage damage. Early recognition is crucial for understanding and managing this complex pathology.

    Area of Science:

    • Orthopedic Surgery
    • Pathology
    • Biomechanics

    Background:

    • Cuff-tear arthropathy is a distinct shoulder lesion linked to rotator cuff tears.
    • The glenohumeral joint's unique anatomy predisposes it to this condition.

    Purpose of the Study:

    • To describe clinical and pathological findings of cuff-tear arthropathy.
    • To discuss differential diagnosis and propose pathomechanics.
    • To highlight the importance of recognizing this entity.

    Main Methods:

    • Clinical and pathological findings in 26 patients were analyzed.
    • A hypothesis on the pathomechanics of cuff-tear arthropathy was developed.

    Main Results:

    • Massive rotator cuff tears lead to synovial leakage, humeral head instability, and subsequent cartilage atrophy and bone osteoporosis.

  • Humeral head migration causes subacromial impingement, eroding the acromion and acromioclavicular joint.
  • Progressive degeneration results in the complete syndrome of cuff-tear arthropathy, potentially involving the glenoid and coracoid.

    • Conclusions:

    • Cuff-tear arthropathy is a distinct pathological entity requiring recognition for better understanding of shoulder impingement lesions.
    • Treatment is challenging; resurfacing total shoulder replacement with rotator-cuff reconstruction is preferred.
    • Consideration of cuff-tear arthropathy is important when deciding on surgical repair for rotator cuff tears.
