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...

Arthroscopic capsular release effectively treats refractory shoulder stiffness, significantly improving range of motion and reducing pain. This minimally invasive procedure offers lasting benefits for patients with persistent shoulder immobility.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Musculoskeletal Disorders

Background:

  • Adhesive capsulitis (frozen shoulder) causes significant shoulder stiffness and pain.
  • Refractory cases often fail to respond to conservative treatments like physical therapy.
  • Surgical intervention may be necessary for persistent shoulder immobility.

Purpose of the Study:

  • To evaluate the long-term outcomes of arthroscopic capsular release for refractory adhesive capsulitis.
  • To compare pre- and postoperative range of motion (ROM) and functional scores.
  • To assess pain reduction following the procedure.

Main Methods:

  • Observational case series of 18 patients with refractory shoulder stiffness.
  • Patients underwent arthroscopic capsular release after a mean of 9.33 months of physical therapy.

  • Minimum follow-up of two years (range: 26–110 months) with ROM and functional score assessments.

    • Main Results:

    • Significant improvements in active and passive forward flexion, external rotation, and internal rotation (p < 0.001).
    • Mean Constant-Murley functional score increased from 14 to 30 points postoperatively.
    • All patients reported diminished shoulder pain post-procedure.

    Conclusions:

    • Arthroscopic capsular release is an effective treatment for refractory shoulder stiffness.
    • The procedure leads to substantial gains in shoulder mobility and function.
    • It provides significant pain relief for patients with persistent frozen shoulder.
