Lecture 17 - Fractures Flashcards
What is the 2 main components of bone structure
What does spongy bone contain?
Red and yellow marrow
In collagen formation what is the difference between lamellar and woven bone?
What are 4 characteristics of bone healing
What are the 2 methods of fractures?
What is the role of osteoporosis in causing fractures
NOTE: Trabeculae breaks down during osteoporosis and that’s where the red blood cells are made
Difference between osteoporotic and normal bone?
Osteoporotic is more porous
NOTE: Trabeculae in photo
What are the 5 primary weight bearing definitions
What are some precautions for a total hip arthroplasty?
- No hip flexion passed 90 degrees (hip instability) -> no putting lotion on or putting on shoes
- no IR and flexion also, no extremes of rotation (IR or ER)
- cannot cross legs across midline (adduction), can teach how to use an adductor pillow
What are some post-op considerations for management and discharge planning
What are some discharge destinations for patients out of acute care?
What is an open fracture?
What is a closed fracture?
What is a displaced fracture
What is an nondisplaced fracture
What are types of fracture patterns?
Whats a vertebral compression fracture
Impact type of fracture that is an anterior wedge (back flexion) most commonly (in back extension it would be posterior wedge). Weight from above and below comes together and the bone cannot resist those forces resulting in a fracture
What is the difference between an incomplete, complete, and comminuted fracture?
What are 4 methods for non-surgical stabilization post-fracture
What are 3 methods of surgical healing post-fracture
Intramedullary Nailing
Placed in the inner medullary canal
External fixation
Internal Fixation
What are the 4 stages of fracture healing
Why is it important to know the stage of fracture healing for an Acute Care PT
Should you do resisted testing over an area of poor bone quality?
NO
Should PT’s consider an OR report
Yes, important to inform clinical decision making and reasoning behind why protocols are in place for each patient
What are some general complications from a fracture
What are some complications following a fracture
What are some hip fracture complications
Osteolytic vs osteoblastic metastases
What are some types of lesions (bone metastases)?
What are some surgical considerations in terms of fractures (metastasis)
What are the effects of bone metastases?
What are 2 important considerations for PT’s in terms of bone metastasis
What is the WB stats decision making based on metastasis
What are precautions for physiotherapy and spinal metastases
What are precautions for physiotherapy for long bones with mets
