Study Notes
Paget's Disease of Bone
- Most common phase: Sclerotic phase
- Hallmark feature of sclerotic phase: Dense, irregular, and disorganized bone formation
- Most common type: Monostotic Paget's disease (affects one bone)
Fractures
- Comminuted fracture: Fragmentation of bone
- Closed fracture: Overlying skin intact
- Open fracture: Communicates with skin surface
- Displaced fracture: Ends of bone at fracture site not aligned
- Stress fracture: Slow-developing fracture following increased physical activity
Bone Characteristics
- Sclerotic phase of Paget's disease: Characterized by dense, irregular, and disorganized bone formation
Factors Affecting Fracture Healing
- Smoking: Can impede or block fracture healing
Ostemyelitis
- Most common cause: Staphylococcus aureus
- Most common cause in GI/IV users: Pseudomonas aeruginosa
- Primary cause of mycobacterial osteomyelitis: Mycobacterium tuberculosis
Tumors
- Leiomyoma: Primary symptom is pain
- Leiomyosarcoma: Most commonly develops in the uterus of adult women
- Alveolar rhabdomyosarcoma: Characterized by small, round cells
- Pleomorphic leiomyosarcoma: Characterized by pleomorphic cells
- Embryonal rhabdomyosarcoma: Characterized by embryonal tissue
- Leiomyosarcoma in extremities: Primary symptom is pain
