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...

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.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Area of Science:

Orthopedic Surgery
Biomedical Engineering
Tissue Healing

Background:

Rotator cuff retears can occur due to strangulation of cuff tissue by sutures.
Optimal tendon healing necessitates suture tension that adapts to rotator cuff muscle activity.

Purpose of the Study:

To present a novel fixation technique for rotator cuff repair that dynamically adjusts suture tension.
To reduce the risk of retear by mimicking natural biomechanics.

Main Methods:

A knot-free tendon trap technique was devised, inspired by the Chinese finger trap mechanism.
This technique resembles a double-pulley-suture bridge but allows for even tension distribution.
Suture limbs respond in synchronization with the cuff tendon.

Main Results:

The technique ensures even sharing of tension across all suture limbs.
The fixation system synchronizes with the natural movements of the cuff tendon.
This method offers a simple and biologic approach to rotator cuff repair.

Conclusions:

The presented knot-free tendon trap technique offers a promising solution for rotator cuff repair.
By mimicking biologic mechanisms, it aims to improve tendon healing and reduce retear rates.
This innovative approach provides a simple, biologic method for repairing rotator cuff tears.
