Muscles that Move the Arm01:31

Muscles that Move the Arm

1.8K
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

3.8K
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...

Muscle Coordination and Action01:24

Muscle Coordination and Action

1.5K
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement....

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering
  • Regenerative medicine

Background:

  • Rotator cuff tears are a frequent cause of shoulder pain and disability.
  • Successful healing of rotator cuff tendons after surgical repair is crucial for patient outcomes.
  • Despite surgical advancements, rotator cuff repair failure rates remain high.

Purpose of the Study:

  • To review commonly available augmentation materials for rotator cuff repair.
  • To discuss the outcomes associated with different types of rotator cuff augments.

Main Methods:

  • Literature review of available rotator cuff augmentation types.
  • Analysis of outcomes data for various graft and synthetic options.

Main Results:

  • Augmentation enhances rotator cuff repair fixation biomechanics.
  • Different augment types (autograft, allograft, xenograft, synthetic) show varied outcomes.
  • Augmentation is associated with improved tendon healing rates.

Conclusions:

  • Augmentation is a valuable strategy to improve rotator cuff repair success.
  • Selection of the appropriate augment type may influence patient outcomes.
  • Further research into optimal augmentation techniques is warranted.
