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...

Posterior shoulder instability, often seen after sports injuries, is increasingly diagnosed and managed. Anatomic, lesion-specific surgical repairs, especially arthroscopic ones, show improved outcomes.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanics

Background:

  • Posterior shoulder instability presents diagnostic and management challenges.
  • Increased diagnosis and treatment, especially post-sports injury.
  • Growing understanding of biomechanics and pathology.

Purpose of the Study:

  • Review literature on the management of posterior shoulder instability.
  • Evaluate open and arthroscopic treatment strategies.

Main Methods:

  • Comprehensive literature review across major medical databases.
  • Analysis of studies on both open and arthroscopic surgical interventions.

Main Results:

  • Increased identification of mechanical factors causing posterior instability (bony and soft-tissue).

Reverse Total Shoulder Arthroplasty

Published on: July 5, 2011

  • Trauma (macro/micro) and congenital causes are recognized.
  • Anatomic stability procedures, often arthroscopic, are increasingly favored over non-anatomic ones.

    • Conclusions:

    • Successful surgical outcomes depend on addressing surgically modifiable mechanical factors.
    • Improved pathology knowledge enables lesion-specific surgical approaches.
    • Arthroscopic, lesion-specific surgery yields better clinical results than non-anatomic procedures.
