Insights

Pectoralis major tendon tears in young patients can be effectively repaired. Surgeons should use two anchors 48.5 mm from the greater tuberosity tip to cover the 46 mm tendon width.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Anatomy

Background:

  • Pectoralis major tendon tears frequently affect young, active individuals.
  • Accurate anatomical repair is crucial for restoring function.

Purpose of the Study:

  • To provide precise anatomical measurements for optimal pectoralis major tendon repair.
  • To guide surgical technique for superior tendon border reattachment.

Main Methods:

  • Ten fresh cadaveric shoulders were dissected.
  • Measurements included pectoralis major tendon insertion width.
  • Distance from the superior tendon border to the greater tuberosity (GT) tip was recorded.

Main Results:

  • The average pectoralis major tendon insertion width was 46 mm.
  • The average distance from the superior tendon border to the GT tip was 48.5 mm.

Conclusions:

  • Optimal repair involves reattaching the superior border of the pectoralis major tendon.
  • Utilize two anchors placed 48.5 mm from the GT tip.
  • This technique ensures coverage of the 46 mm tendon width for robust healing.

Anatomy of the Brain: Major Regions01:20

Anatomy of the Brain: Major Regions

The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...

Anatomy of the Heart01:27

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Anatomy of the Circulatory System02:03

Anatomy of the Circulatory System

The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.

Major Organs of the Digestive System

The digestive system is responsible for the ingestion of food, secretion of enzymes, mixing and digesting food, absorption of the nutrients and defecation. The human digestive system consists of two major parts: the gastrointestinal tract and the accessory digestive organs.

Major Losses in Pipes01:28

Major Losses in Pipes

When a fluid flows through a pipe, it experiences energy losses due to frictional resistance along the pipe walls, known as major losses. These energy losses result in a pressure drop, which varies based on the flow conditions — whether laminar or turbulent — and the specific physical properties of the fluid and pipe.
Fluid flow can be classified as laminar or turbulent, primarily based on the Reynolds number. This dimensionless number reflects the relative influence of inertial to viscous...

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...
