Questions and Answers

What is osteoporosis?

A disorder characterized by normal bone mass and increased bone fragility

A disorder characterized by low bone mass and increased bone fragility (correct)

A disorder characterized by low bone mass and decreased bone fragility

A disorder characterized by high bone mass and increased bone fragility

What is osteoporosis?

A systemic disorder characterized by low bone mass and increased bone fragility (correct)

A skeletal disorder characterized by high bone mass and low bone fragility

A muscular disorder characterized by low bone density and decreased bone strength

An autoimmune disorder characterized by high bone density and increased bone fragility

What are the two types of bone cells and how do they respond to different hormones?

The two types of bone cells are osteoblasts and osteoclasts. Osteoblasts build bone while osteoclasts break down bone in response to different hormones.

What is the recommended diagnostic test for osteoporosis and what T-score indicates the presence of osteoporosis?

The recommended diagnostic test for osteoporosis is DXA scan. A T-score of less than -2.5 indicates the presence of osteoporosis. Signup and view all the answers

Study Notes

Overview of Osteoporosis, Bone Cells, and BMD:

Osteoporosis is a systemic skeletal disorder characterized by low bone mass and increased bone fragility.
Bone cells include osteoblasts and osteoclasts, which respond to different hormones.
BMD is measured via DXA scan and a T-score of less than -2.5 indicates osteoporosis.

Screening and Diagnosis of Osteoporosis:

Basic bone health measures include exercise, calcium and vitamin D intake, and fall prevention.
Fragility fractures, risk factors, and secondary osteoporosis are indications for screening.
Recommended biochemical tests include serum calcium, vitamin D, and CBC.
Risk stratification is based on the 10-year fracture risk, calculated using the CAROC tool or FRAX questionnaire.

Treatment of Osteoporosis:

Non-pharmacological therapies include exercise, lifestyle changes, and calcium and vitamin D supplementation.
Pharmacological therapies include bisphosphonates, denosumab, and other agents.
Contraindications for bisphosphonates include denosumab therapy, pregnancy, and CKD.
