Regional migratory osteoporosis. A denervation disease
Arthritis and Rheumatism
|September 1, 1978
Summary
Regional migratory osteoporosis causes sudden lower limb pain and swelling. Electromyography studies over nine years revealed nerve damage (denervation) during attacks, offering diagnostic and pathogenetic insights.
Area of Science:
- Orthopedics
- Neurology
- Radiology
Background:
- Regional migratory osteoporosis (RMO) is a rare condition causing migrating lower limb pain, edema, and muscle atrophy.
- The exact causes and mechanisms of RMO remain largely unknown.
- Diagnosis is typically supported by imaging findings like demineralization and bone scan abnormalities.
Observation:
- A nine-year case study of RMO is presented.
- Serial electromyographic (EMG) studies were conducted throughout the observation period.
- EMG documented denervation patterns that coincided with the timing and location of acute RMO attacks.
Findings:
- The study provides evidence of nerve involvement in RMO.
- Denervation patterns were observed to be temporally and spatially linked to RMO episodes.
- This substantiates a potential neurological component in the disease process.
Implications:
- The findings suggest that denervation is significant in understanding RMO.
- This could lead to improved diagnostic approaches for RMO.
- Further research into the pathogenetic role of denervation may uncover new therapeutic targets.

01:40Bone Remodeling
34.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:31Osteoclasts in Bone Remodeling
3.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

01:29Blood and Nerve Supply to the Bones
15.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

8.0K
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...

01:27Degenerative Disc Disease I: Introduction
29
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
30
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...
