Osteoporosis

Updated : September 4, 2023





Background

Decreased mineral density in bones brought on by changed bone morphology is known as osteoporosis, which ultimately predisposes individuals to brittle fractures with low force. Life quality is significantly reduced as a result of osteoporotic fractures, which also raise morbidity, disability, and mortality.

White postmenopausal women will get an osteoporotic-related injury in over 50 percent of cases. About 33 percent of elderly women with hip fractures may regain their independence. The probability of an osteoporotic fracture in white men is 20%, while male hip fracture mortality in the first year is double that of female hip fracture mortality.

Despite having lower rates of osteoporosis than their white counterparts, black men and women nevertheless face the same risk of fracture. The number of bone fractures is predicted to increase as the American population ages.

Epidemiology

Osteoporosis affects more than 200 million people worldwide, and the prevalence rises with advancing age. The impacted population is almost 70 percent of those over 80. Males are less likely to experience it than females. The male and female prevalence varies between 2 percent and 8 percent and 9 percent to 38 percent in the developed world.

Osteoporosis causes about nine million fractures annually throughout the world. An osteoporotic fracture will occur in 1 in 3 females and 1 in 5 males over the age of 50. Compared to persons living at lower latitudes, regions of the world with less vitamin D from sunlight experience a higher incidence of fracture.

Anatomy

Pathophysiology

Osteoporosis is brought on by an imbalance between bone remodeling and resorption, which results in a loss of skeletal mass. Bone mass typically reaches its peak in the third decade, following which bone resorption outpaces bone growth. Osteoporosis can result from bone loss speeding up or not reaching a normal peak bone mass.

Etiology

The process of aging and a drop in sex hormones are both factors that contribute to primary osteoporotic fractures. The bones show signs of microarchitecture degeneration, which causes loss of bone mineral content and increases the chance of fracture. Osteoporosis is secondary to another condition or its treatment.

Secondary osteoporosis affects men far more frequently than it does women. Glucocorticoids and anti-epileptic medications are two examples of drugs that might cause secondary osteoporosis. Although they haven’t been thoroughly explored, other drugs such as proton pump inhibitors, thiazolidines, and chemotherapeutic medicines are thought to play a role in osteoporosis.

Hyperparathyroidism, malabsorption, anorexia, hyperthyroidism, and overtreatment of chronic renal failure hypothyroidism, Cushing syndrome, and thus any condition that can result in prolonged immobility are diseases that can induce osteoporosis. Rapid bone mass loss can also result from secondary amenorrhea that lasts longer than a year due to a variety of factors, such as non-estrogen hormone treatment, low body weight, and severe exercise.

Aging, being under 128 pounds, smoking, being Asian or white, going through premature menopause, being inactive, and having a history of fractures from minor trauma or ground-level falls after the age of 40 are all possible causes of osteoporosis. Within the first two weeks following these crippling injuries, patients with diseases like spinal cord accidents that compromise general mobility levels may see a significant decline in bone mass levels.

In the following, there is a high chance of fracture:

  • Mature age
  • Prior experience with a fracture
  • Gender: Female
  • Corticosteroid use
  • a low BMI
  • History of smoking
  • Added (Secondary) osteoporosis
  • Consuming alcohol

Genetics

Prognostic Factors

The outcomes are positive if osteoporosis is identified and treated early. However, if the issue is left untreated, it can result in fractures and persistent pain. Exercise, a calcium-rich diet, and the use of bisphosphonates can all reduce the risk of osteoporosis.

Surprisingly, bisphosphonates not only cost a lot of money but also have adverse effects. Additionally, it is still up for debate whether they will lessen fractures. In general, postmenopausal women continue to have a significant chance of developing a broken hip, which frequently necessitates extended recuperation and care home placement.

Another frequent injury is vertebral fracturing, which increases the risk of pneumonia, kyphosis, persistent discomfort, and respiratory problems. Due to their inability to perform, the majority of patients lose their capacity to live freely.
