E Moskowitz, E S Rashkoff

    Connecticut Medicine
    |November 1, 1989
    PubMed
    Summary

    Isolated traumatic suprascapular nerve palsy is rare. Diagnosis involves specific shoulder weakness and muscle atrophy, confirmed by electromyography excluding other nerve issues.

    Area of Science:

    • Orthopedics
    • Neurology
    • Sports Medicine

    Background:

    • Suprascapular nerve palsy can occur in isolation, without fractures.
    • Understanding this rare condition is crucial for accurate diagnosis and treatment.

    Observation:

    • Localized muscle atrophy in the supraspinatus and infraspinatus muscles.
    • Weakness in initiating shoulder abduction and external rotation.

    Findings:

    • Diagnosis is suggested by specific muscle atrophy and weakness patterns.
    • Electromyography confirms suprascapular nerve palsy by ruling out nerve root or brachial plexus involvement.

    Implications:

    • Early diagnosis of isolated suprascapular nerve palsy is key.
    • Accurate diagnosis prevents mismanagement and guides appropriate therapeutic interventions.
