Study Notes
Osteitis Deformans
- Osteitis deformans is most common in older adults.
Paget's Disease
- The hallmark feature of the 'burned-out' osteosclerotic stage of Paget's disease is a mixed pattern of bone resorption and formation.
- The most common type of Paget's disease presentation involving multiple bones is polyostotic.
- The enlargement of the facial skeleton seen in Paget's disease is called leontiasis ossea.
- Bisphosphonates are commonly used to suppress mild symptoms of Paget's disease.
Genetics of Paget's Disease
- The SQSTM1 gene mutation is associated with increased osteoclastic activity in Paget's disease.
Fractures
- Stress fractures are the most common type of fracture resulting from a mechanical injury or failure with diminished bone strength.
- Open fractures communicate with the skin surface.
- Fatigue fractures are slow-developing fractures following a period of increased physical activity.
- Comminuted fractures involve fragmentations of the bone.
- Factors that can impede fracture healing include smoking, diabetes, and vitamin D deficiency.
Osteomyelitis
- Pyogenic osteomyelitis is most commonly caused by Staphylococcus aureus.
- Mycobacterium tuberculosis is the cause of 40% of cases of tubercular spondylitis.
Bone Tumors
- Leiomyomas are the most common type of muscle tumor in the uterus and can cause infertility and menorrhagia.
- Embryonal rhabdomyosarcoma develops in the walls of hollow viscera like the urinary bladder or vagina.
Fracture Healing
- A malformed callus that undergoes cystic degeneration and forms a false joint is called a pseudoarthrosis.
- Woven bone is the type of bone initially deposited in the fracture gap during the healing process.
Osteonecrosis (Avascular Necrosis)
- The primary cause of osteonecrosis is interruption of blood supply to the bone.
- The most common cause of mechanical disruption of vessels leading to osteonecrosis is fracture.
