[VERTEBRAL SUBCHONDRAL BONE AND INTERVERTEBRAL DISC DEGENERATION]
Summary
Vertebral subchondral bone maintains disc health by cushioning stress and supplying nutrients. Abnormalities like sclerosis impair these functions, accelerating intervertebral disc degeneration.
Area of Science:
- Orthopedics
- Spinal Anatomy
- Degenerative Disc Disease Research
Background:
- The vertebral subchondral bone, a critical component of the vertebral endplate, plays a vital role in spinal health.
- Its anatomical and microstructural features are essential for intervertebral disc (IVD) physiology.
Purpose of the Study:
- To elucidate the multifaceted role of vertebral subchondral bone in maintaining normal intervertebral disc function.
- To investigate its contribution to the pathogenesis of intervertebral disc degeneration.
Main Methods:
- Comprehensive literature review of domestic and international studies.
- Analysis focused on bone anatomy, microstructure, histopathology, and MRI imaging features.
Main Results:
- Vertebral subchondral bone cushions stress, resists hydrostatic pressure, and ensures disc nutrition.
- Abnormal bone remodeling leading to sclerosis impairs stress absorption and nutrient supply.
- This dysfunction promotes inflammation and accelerates intervertebral disc degeneration.
Conclusions:
- Understanding vertebral subchondral bone's role is crucial for advancing research into intervertebral disc degeneration.
- Further investigation into this area will enhance knowledge of IVD pathogenesis.

General Structure of a Vertebra
8.2K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

Structural Joints: Cartilaginous Joints
4.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Vertebral Column: Regions and Curvature
11.5K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Bone Disorders
7.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Spinal Cord: Gross Anatomy
7.2K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

Changes in the Appendicular Skeleton with Age
4.0K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
