Age changes in the lumbar articular triad
The Australian Journal of Physiotherapy
|July 16, 2014
Summary
Aging alters spinal structures, increasing intervertebral disc size and causing cartilage changes in zygapophyseal joints. These age-related spinal modifications reduce lumbar movement range in older adults.
Area of Science:
- Orthopedics
- Gerontology
- Biomechanics
Background:
- The articular triad, comprising the intervertebral disc and zygapophyseal joints, is crucial for spinal mobility, support, and protection.
- Understanding age-related changes in this triad is essential for addressing mobility limitations in the elderly.
Purpose of the Study:
- To investigate the structural alterations within the articular triad in old age.
- To correlate these structural changes with the observed reduction in lumbar spine mobility.
Main Methods:
- Descriptive analysis of age-related structural changes in the intervertebral disc and zygapophyseal joints.
- Correlation of observed morphological changes with functional range of motion data for the lumbar spine.
Main Results:
- Increased convexity, central height, and horizontal dimensions of the intervertebral disc in old age.
- Zygapophyseal joint cartilage exhibits swelling and fibrillation, with osteophyte formation expanding joint margins.
- Despite advanced osteoarthrosis, bony sclerosis is absent due to generalized osteopenia in old age.
Conclusions:
- Age-associated structural modifications of the articular triad directly lead to decreased lumbar movement.
- Osteopenia in old age influences the presentation of osteoarthrosis, preventing bony sclerosis.

3.4K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:27Degenerative Disc Disease I: Introduction
24
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

01:23Degenerative Disc Disease ll: Pathophysiology
21
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

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...

8.1K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...
