Study Notes
Bone Conditions
- Non-displaced fracture is a condition where the bone is broken but fragments remain intact.
- Osgood-Schlatter disease is characterized by inflammation of the patellar ligament at the tibial tuberosity.
- Compression fracture is a condition where the bone is compressed but not completely broken.
- Osteoporosis is a condition that results in gradual loss of bone density, thinning of cortex, and trabeculae.
- 'Frog leg appearance' is associated with cleidocranial dysplasia.
- Osteogenesis imperfecta is a 'brittle bone disease' that results from reduced osteoblast activity.
Bone Structure
- Subchondral bone is the layer of bone beneath articular cartilage that covers the ends of bones at joints.
- Subchondral bone becomes eburnated bone as new bone is formed.
Bone Abnormalities
- Smudged and indistinct trabeculae in bone tissue are characteristic of osteomalacia.
- Coarsening of trabeculae and osteopenia (decreased bone density) is characteristic of osteoporosis.
- Delicate trabeculae bone appearance is characteristic of osteogenesis imperfecta.
Radiology
- X-ray displays wasting or atrophy as diminished bone density.
- X-ray reveals gross swelling as increased bone density.
- In cases of joint injury or trauma, accumulation of fluid and swelling can cause joint effusion.
Conditions
- Codman's triangle is associated with bone cancer.
- Delicate trabeculae bone appearance is associated with osteogenesis imperfecta.
- Periosteum is the fibrous membrane that covers the outer surface of bones and plays a role in healing.
- Cervical rib is a condition characterized by an extra rib that articulates with C7.
Bone Diseases
- Osteomyelitis is a condition characterized by inflammation of bone and bone marrow, with pus production in acute cases.
- Tibial plateau fracture is a condition where the articular surface of the tibia is intact but there is a fracture.
- Scoliosis is a condition characterized by lateral curvature in the spine.
- Gout is a condition characterized by excessive uric acid in the blood and around joints.
- Gas in soft tissue indicates gas gangrene or trauma.
