Muscles of the Shoulder

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.

The anterior thoracic muscles include the serratus anterior, subclavius, and...

Muscles that Move the Arm

Muscles that Move the Arm

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...

Summary

This summary is machine-generated.

Posterior shoulder instability (PSI) affects athletes due to trauma and causes persistent pain. Surgical repair via arthroscopy is recommended when nonoperative treatments fail.

Area of Science:

Orthopedic Surgery
Sports Medicine
Biomechanics

Background:

Posterior shoulder instability (PSI) accounts for 10% of shoulder instability cases.
It is common in contact sport athletes from recurrent blunt shoulder trauma.
PSI symptoms include persistent pain and can be diagnosed with specific clinical tests.

Purpose of the Study:

To review the current literature on posterior shoulder instability.
Discuss the etiology, diagnosis, and treatment options for PSI.
Outline rehabilitation strategies following surgical intervention for PSI.

Main Methods:

Literature review of studies on posterior shoulder instability.
Analysis of diagnostic methods including the Kim test and Jerk test.
Evaluation of surgical techniques, primarily arthroscopic posterior labral repair.

Main Results:

Nonoperative treatment is often insufficient for athletes with PSI.
Arthroscopic posterior labral repair is the primary surgical approach.
The goal of surgery is to reduce recurrent instability and pain.

Conclusions:

PSI requires prompt diagnosis and appropriate management.
Surgical intervention is often necessary for athletes to return to sport.
Comprehensive rehabilitation is crucial for optimal outcomes after PSI surgery.
