Muscles of the Shoulder01:23

Muscles of the Shoulder

9.3K
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

5.5K
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:

  • Orthopedics
  • Sports Medicine
  • Musculoskeletal Research

Background:

  • Partial-thickness rotator cuff tears are frequently underdiagnosed shoulder conditions causing pain and functional loss.
  • These tears affect diverse age groups and can advance to full-thickness tears if not addressed.
  • Tear location influences pain severity and progression risk.

Purpose of the Study:

  • To review the diagnosis and management of partial-thickness rotator cuff tears.
  • To emphasize the importance of early intervention for optimal patient outcomes.

Main Methods:

  • Diagnosis involves physical examination, clinical suspicion, and imaging (ultrasound, MRI, arthroscopy).
  • Conservative management includes physiotherapy and various injections (e.g., Platelet-Rich Plasma).
  • Surgical arthroscopic repair is considered if conservative methods fail.

Main Results:

  • Conservative treatment typically lasts 3-6 months.
  • Arthroscopic repair, followed by rehabilitation, generally yields good to excellent functional results.
  • Timely intervention prevents progression to irreparable damage or cuff arthropathy.

Conclusions:

  • Accurate diagnosis and personalized treatment plans are essential for partial-thickness rotator cuff tears.
  • Preventing tear progression ensures better long-term shoulder function and patient satisfaction.
