Summary

Magnetic resonance imaging reveals common injuries after traumatic posterior shoulder dislocation, including reverse Hill-Sachs lesions in 86% and labrocapsular tears in 58% of patients. Rotator cuff tears occurred in about 20%.

Muscles of the Shoulder01:23

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Area of Science:

  • Orthopedic imaging
  • Musculoskeletal radiology
  • Traumatology

Background:

  • Traumatic posterior shoulder dislocation is a significant injury.
  • Understanding the associated osseous and soft-tissue damage is crucial for effective management.
  • Magnetic resonance (MR) imaging is a key modality for evaluating these injuries.

Purpose of the Study:

  • To retrospectively analyze the MR imaging findings of glenohumeral joint structures following first-time traumatic posterior shoulder dislocation.
  • To identify the prevalence of specific lesions, including reverse Hill-Sachs lesions, rotator cuff tears, and labrocapsular complex injuries.

Main Methods:

  • Retrospective review of MR imaging (MR arthrography or conventional) in 36 male patients with first-time traumatic posterior shoulder dislocation.

Reverse Total Shoulder Arthroplasty

Published on: July 5, 2011

  • Evaluation of lesions including Hill-Sachs, rotator cuff tears, biceps tendon abnormalities, labrocapsular complex injuries, humeral head translation, and glenoid version.
  • Statistical analysis using Spearman rank correlation and Student t test.

    • Main Results:

    • Reverse Hill-Sachs lesions were present in 86% of patients.
    • Posterior labrocapsular complex tears, including reverse Bankart lesions, were identified in 58% of patients.
    • Full-thickness rotator cuff tears were observed in 19% of patients, and biceps tendon abnormalities in 17%.

    Conclusions:

    • MR imaging findings in traumatic posterior shoulder dislocation are predominantly characterized by reverse Hill-Sachs lesions and posterocaudal labrocapsular injuries.
    • A significant proportion of patients also exhibit rotator cuff tears and other soft-tissue abnormalities.
    • These findings highlight the common injury patterns associated with this type of shoulder dislocation.
