The Hill-Sachs lesion. An experimental study

L A Danzig, G Greenway, D Resnick

    The American Journal of Sports Medicine
    |September 1, 1980
    PubMed
    Summary

    Diagnosing Hill-Sachs lesions, a sign of shoulder dislocation, can be improved with specific X-ray views. Three optimal roentgenographic projections are identified for accurate detection in clinical settings.

    Area of Science:

    • Orthopedic Surgery
    • Radiology
    • Sports Medicine

    Background:

    • Hill-Sachs lesions are common indicators of prior anterior shoulder dislocation.
    • Accurate diagnosis is crucial for effective treatment and management of recurrent dislocations.

    Purpose of the Study:

    • To evaluate and identify optimal roentgenographic projections for detecting Hill-Sachs lesions.
    • To compare standard and novel radiographic views in cadaveric and clinical settings.

    Main Methods:

    • Creation of Hill-Sachs lesions in cadaveric humeri.
    • Radiographic imaging of cadaveric humeri using standard and fluoroscopic-guided projections.
    • Clinical evaluation of 15 patients with recurrent anterior shoulder dislocations using standard and new roentgenographic projections.

    Main Results:

    • Identification of three optimal roentgenographic views for detecting Hill-Sachs lesions.
    • The optimal views include: anteroposterior (AP) view with 45° internal rotation, the Stryker (notch) view, and the modified Didiee view.

    Conclusions:

    • Specific radiographic projections significantly enhance the detection of Hill-Sachs lesions.
    • The recommended three-view protocol provides an optimal method for diagnosing these injuries.
