What is the difference between osteoporosis and osteomalacia?
In osteoporosis, the bones are porous and brittle, whereas in osteomalacia, the bones are soft. This difference in bone consistency is related to the mineral-to-organic material ratio.
What is the pathophysiology of osteomalacia?
Pathophysiology. Osteomalacia is characterized by a deficient mineralization of bone without a loss in bone matrix. Dietary deficiency of vitamin D or, less commonly, phosphorus or calcium may be causative.
What is the pathophysiology of osteoporosis?
The hallmark of osteoporosis is a reduction in skeletal mass caused by an imbalance between bone resorption and bone formation. Under physiologic conditions, bone formation and resorption are in a fair balance. A change in either—that is, increased bone resorption or decreased bone formation—may result in osteoporosis.
What is the difference between osteoporosis and osteoporotic?
Osteoporotic fractures are a result of osteoporosis, a condition in which the bones become more fragile due to bone deterioration or low bone mass. Bones that are weaker or more fragile are at greater risk for fractures. Fractures occur commonly in the spine.
What is the difference between osteoporosis and scoliosis?
Scoliosis is a curvature of the spine that primarily appears in younger patients, while osteoporosis is a degenerative bone condition affecting mainly aging patients. We should also note that it is possible for a person to suffer from both scoliosis and osteoporosis simultaneously.
What is the difference between osteoporosis and osteoarthritis?
If you have osteoporosis, your bones become weak and brittle, causing you to be at greater risk for bone fractures. Osteoarthritis is the most common type of arthritis, which is inflammation and deterioration of your joints. Osteoarthritis is the result of every day wear and tear, and is most common in older adults.
What is the pathophysiology of osteomyelitis?
Pathophysiology of Osteomyelitis Osteomyelitis tends to occlude local blood vessels, which causes bone necrosis and local spread of infection. Infection may expand through the bone cortex and spread under the periosteum, with formation of subcutaneous abscesses that may drain spontaneously through the skin.
What is osteomyelitis of the bone?
Osteomyelitis is inflammation or swelling that occurs in the bone. It can result from an infection somewhere else in the body that has spread to the bone, or it can start in the bone — often as a result of an injury. Osteomyelitis is more common in younger children (five and under) but can happen at any age.
Is pathophysiology and causes the same?
Pathophysiology (consisting of the Greek origin words “pathos” = suffering; “physis” = nature, origin; and “logos” = “the study of”) refers to the study of abnormal changes in body functions that are the causes, consequences, or concomitants of disease processes.
What is the difference between physiology and pathophysiology?
Pathophysiology is the convergence of pathology (the discipline of observed changes in a diseased state) with physiology (the mechanisms of systems operation). It represents the functional changes that occur because of injury or disease.
What is the relationship between osteoporosis and osteomalacia?
In osteoporosis, there is decreased bone mass with a normal ratio of mineral to matrix. In this iliac crest biopsy, below, osteomalacia is seen. Osteoporosis causes decreased bone mass, with a normal ratio of bone mineral to matrix in addition to altered bone microarchitecture.
How does osteomalacia affect height?
Osteomalacia or Osteoporosis. This can be painful and it leads to lessened height.in several aspects. Osteoporosis is a disease in which there is a decrease bone density; meaning that for a particular volume of bone there is too little calcium an d phosphorous in bones due to which the bones becomes fragile and porous.
Osteoporosis causes decreased bone mass, with a normal ratio of bone mineral to matrix in addition to altered bone microarchitecture. The catch-phrase of osteoporosis is “normal-enough bone, but not enough of it!”
Which lab values are characteristic of osteomalacia?
Lab values of serum calcium, phosphorus and alakaline phosphatase are not diagnostic. Osteomalacia is characterized by a decreased ratio of bone mineral to matrix. Osteomalacia when it appears in children is called rickets”, seen below
