Muscles of the Shoulder01:23

Muscles of the Shoulder

6.8K
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

3.0K
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...

Muscles of the Thorax

2.4K
The thorax muscles are central to the body's respiration and provide essential support and movement for the upper body. They are intricately designed to facilitate the complex breathing process while also contributing to the structural integrity and mobility of the chest and upper limbs.
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It...

Summary
This summary is machine-generated.

Pathologic shortening of the pectoralis minor (PM) muscle can cause shoulder pain and scapular dyskinesis in athletes. Isolated PM release surgery effectively reduces pain and improves function in cases unresponsive to conservative treatment.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Anatomy

Background:

  • Pathologic shortening of the pectoralis minor (PM) muscle is common in overhead athletes.
  • Shortened PM can lead to scapular dyskinesis, internal rotation of the scapula, and anterior shoulder pain.
  • Conservative treatments like physical therapy may not resolve symptoms in all cases.

Purpose of the Study:

  • To describe the arthroscopic pectoralis minor release procedure.
  • To evaluate the efficacy of isolated PM release in athletes with recalcitrant shoulder pain and scapular dyskinesia.

Main Methods:

  • Arthroscopic pectoralis minor release performed in the beach-chair position.
  • Focus on athletes with persistent shoulder pain and scapular dyskinesia unresponsive to conservative management.

Main Results:

  • The procedure is safe and effective for reducing self-reported pain.
  • Significant decrease in activity limitations was observed post-procedure.
  • Successful management of recalcitrant shoulder pain and scapular dyskinesia.

Conclusions:

  • Isolated arthroscopic pectoralis minor release is a viable treatment option.
  • The procedure effectively addresses pain and functional deficits associated with PM shortening.
  • This technique offers a solution for athletes with refractory shoulder pathologies.
