Muscles of the Shoulder01:23

Muscles of the Shoulder

9.2K
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...

Muscles that Move the Arm

5.4K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Military Health

Background:

  • Shoulder instability is prevalent in military populations.
  • This demographic has a high risk of recurrence after initial injury.
  • Surgical intervention is frequently necessary for high-demand individuals.

Purpose of the Study:

  • To highlight the importance of recognizing glenoid bone loss in shoulder instability.
  • To guide the selection between arthroscopic repair and bony reconstruction.
  • To emphasize optimal care through understanding pathology and treatment options.

Main Methods:

  • Review of current literature on shoulder instability in military populations.
  • Analysis of diagnostic methods for identifying glenoid bone loss.
  • Evaluation of surgical techniques for shoulder instability.

Main Results:

  • Accurate assessment of glenoid bone loss is critical for surgical decision-making.
  • Surgical management offers a predictable return to military duties.
  • Understanding associated anatomic lesions aids in treatment selection.

Conclusions:

  • Optimal management of shoulder instability in the military requires precise diagnosis.
  • Selection between arthroscopic capsulolabral repair and bony reconstruction depends on bone loss.
  • A comprehensive approach to pathology, diagnostics, and treatment ensures the best outcomes.
