Discussion: - most common metabolic bone dz; - definition: - what appears to be a characteristic of osteoporosis is an uncoupling of the osteoblastic and osteoclastic processes; - WHO definition: a bone mineral density that is 2.5 SD below the mean peak value in young adults of the same race and sex (T-score of -2.5); - Z score: bone mineral density compared with the mean value in normal subjects of the same age and sex; - Z-score of less than -1 indicates patient is in the lowest 25%, and a score of less than -2 indicates patient is in the lowest 2.5%; Wheeless' Textbook of Orthopaedics

Evaluation of Patients With a Recent Clinical Fracture and Osteoporosis Medscape

The purpose of this study was to determine the prevalence of contributors to secondary osteoporosis (eg osteomalacia) in patients presenting with a clinical vertebral or non-vertebral fracture. Identifying and correcting these contributors will enhance treatment effect aimed at reducing the risk of subsequent fractures.
We conclude that more than one in two patients presenting with a clinical vertebral or non-vertebral fracture and BMD-osteoporosis have secondary contributors to osteoporosis, most of which were correctable. Identifying and correcting these associated disorders will enhance treatment effect aimed at reducing the risk of subsequent fractures in patients older than 50 years.

Vertebral compression fracture is the most common complication of osteoporosis. More than 700,000 new vertebral compression fractures occur every year in the United States alone, accounting for more than 100,000 hospital admissions and resulting in close to $1.5 billion in annual costs.

Osteoporosis and Spinal Cord Injury eMedicine PMR

David Weiss, MD — 2008-08-10 09:09:23 GMT

One of the inevitable complications of spinal cord injury (SCI) is the associated osteoporosis that occurs predominantly in the pelvis and the lower extremities. The acute treatment of patients with SCI has always focused on the injury itself and on the immediate complications that subsequently arise. Bone loss as a consequence of SCI has been of secondary concern historically. Osteoporosis in persons with SCI was first studied in relation to calcium metabolism and the associated hypercalcemia and renal calculi that followed. The differences between SCI-induced osteoporosis and other causes of bone loss (disuse), such as prolonged bed rest, space travel, and lower motor neuron disorders, have since become clearer. New technologies allow monitoring of osteoblastic and osteoclastic activity at the microscopic level, while modern radiographic techniques have allowed more refined studies to be undertaken at the macroscopic level.

Osteoporosis eMedicine Orthopedics

Lin & Lane — 2008-04-10 09:09:23 GMT

Osteoporosis is the most common metabolic bone disease and represents an increasingly serious problem, particularly as the population ages. It has been most commonly recognized in elderly white women, although it does occur in both sexes, all races, and all age groups. Osteoporosis is defined by the World Health Organization as a T-score of -2.5. T-score is the value compared to control subjects who are at their peak bone mineral density, while Z-score reflects a value compared to patients matched for age and sex.
Osteoporosis can result in devastating physical, psychosocial, and economic consequences. Despite its adverse effects, it is a condition that is often overlooked and undertreated, in large part because it is a clinically silent disease until it manifests in the form of fracture.

Osteoporosis eMedicine Pediatrics

Gordon L Klein, MD, MPH — 2008-08-10 09:09:23 GMT

the official definition of osteoporosis does not pertain to children at the present time. However, at an NIH Consensus Conference in 2000, osteoporosis was defined as a skeletal disorder characterized by compromised bone strength that predisposes to an increased risk of fracture. Adult-onset osteoporosis also involves loss of bone trabecular structure; however, no evidence indicates that this occurs in children. Therefore, children exhibiting low bone mass are defined as osteopenic, not osteoporotic.

Osteoporosis Primary eMedicine PMR

Nalamachu & Nalamasu — 2008-04-15 09:09:23 GMT

Osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to bone fracture.
Bone tissue undergoes constant remodeling. Under the physiologic conditions, bone formation and resorption are in a fair balance. After the third decade of life, bone resorption exceeds bone formation and leads to osteopenia and, in severe situations, osteoporosis. Women lose 30-40% of their cortical bone and 50% of their trabecular bone over their lifetime, as opposed to men who lose 15-20% of their cortical bone and 25-30% of trabecular bone.

Osteoporosis Secondary eMedicine PMR

Serota et al — 2008-04-15 09:09:23 GMT

Osteoporosis, a chronic progressive disease, is the most common metabolic bone disease in the United States. Osteoporosis can affect almost the entire skeleton. Osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility. The disease often does not become clinically apparent until a fracture occurs. Consequently, many individuals, both male and female, experience pain, disability, and diminished quality of life as a result of having osteoporosis. The economic burden of the disease in the United States is considerable and will grow as the population ages. Prevention and recognition of the secondary causes of osteoporosis are first-line measures to lessen the impact of osteoporosis.

Jeffrey P Kochan, MD — 2008-08-10 09:09:23 GMT

Vertebroplasty and kyphoplasty are radiologic procedures for the treatment of the intense pain caused by vertebral compression fracture in patients whose pain has been refractory to medical management or bracing. Vertebroplasty and kyphoplasty involve the US Food and Drug Administration (FDA) approved intraosseous injection of acrylic cement under local anesthesia and fluoroscopic guidance to control the pain of vertebral fractures associated with osteoporosis, tumors, and trauma.
