Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

13.6K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.6K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Muscle Coordination and Action01:24

Muscle Coordination and Action

3.6K
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....

Muscles of the Shoulder01:23

Muscles of the Shoulder

10.4K
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 Arm01:31

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...

Summary

Arthroscopic rotator cuff repair techniques, including single-row versus double-row, show similar outcomes. Factors like age and rupture size impact results, and platelet-rich plasma augmentation offers no significant healing benefit.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Regenerative Medicine

Background:

  • Rotator cuff tears are common injuries affecting shoulder function.
  • Arthroscopic repair techniques have evolved, aiming for improved patient outcomes.
  • Understanding factors influencing repair success and alternatives for irreparable tears is crucial.

Purpose of the Study:

  • To review current trends in arthroscopic rotator cuff repair techniques.
  • To evaluate factors influencing repair outcomes and long-term results.
  • To analyze treatment options for irreparable rotator cuff ruptures and the role of platelet-rich plasma.

Main Methods:

  • Systematic review of current literature on arthroscopic rotator cuff repairs.
  • Comparison of single-row versus double-row repair techniques.
  • Analysis of influencing factors (age, fatty infiltration, tear size) and augmentation with platelet-rich plasma.

Main Results:

  • Double-row repairs did not demonstrate superior clinical results or lower re-rupture rates compared to single-row repairs.
  • Patient age, degree of fatty infiltration, and initial tear size significantly influence repair outcomes.
  • Platelet-rich plasma augmentation did not show significant differences in healing rates compared to conventional repairs.

Conclusions:

  • Current evidence does not support double-row repairs over single-row repairs for arthroscopic rotator cuff reconstruction.
  • Patient-specific factors are critical determinants of successful rotator cuff repair outcomes.
  • Platelet-rich plasma offers no proven advantage in enhancing healing rates for rotator cuff repairs.
