100
This artery is often damaged with a fracture dislocation of the tibial plateau
What is the popliteal artery?
100
The 3 types on non-unions.
What is hypertrophic, oligotrophic, and atrophic?
100
Type of stability with no motion.
What is absolute stability?
100
These are excellent for cortical/dense bone
What is a cortical screw?
100
Provides a scaffold that aids in growth of blood vessels and new bone
What is osteoconductive?
200
The 3 bones that make up the knee joint.
What is the tibia, patella & femur.
200
The 4 sources of fractures.
What is trauma, cancer, osteoporosis, infection?
200
Converts tension forces into compressive forces, thereby providing absolute stability.
What is the principle of tension band plating?
200
These screws are designed to find purchase in 2 layers of cortex for weakened bone.
What is a bicortical screw?
200
“Gold Standard”
What is autograft?
300
The 4 main ligaments of the knee.
What is the ACL, PCL, MCL, and LCL.
300
Where the articular surface is displaced into the bone.
What is a depression?
300
Acts like an internal “external fixator" with locking screws; good for poor quality bone, communited areas, near metaphysis.
What is a locking plate?
300
Has a hollow center that allows it to be passed over a guide wire.
What is a cannulated screw?
300
Very good compressive strength, isothermic, forms HA. Resorption in 1-3 years.
What is Calcium Phosphate?
400
This part of the plateau is higher & convex in the sagittal and coronal axes.
What is the Lateral plateau?
400
Fracture that breaks the skin.
What is an open or compound fracture?
400
This is used in percutaneous procedures to place screws in the proper place.
What is a radiolucent outrigger?
400
Broader-surface contact: distributes force evenly.
What is lag screw technique?
400
Resorption in 6 weeks until 6 months. Often used for infection.
What is Calcium Sulfate?
500
This part of the plateau is larger & concave in the sagittal & coronal axes
What is the Medial plateau?
500
Shatzker type with split and depression of the lateral plateau.
What is Shatzker Type II?
500
These plates are commonly used for multifragmented diaphyseal and metaphyseal fractures.
What are buttress plates?
500
These are the functions of screws.
What is screw positioning, compression, plate holding, locking bolt, and anchor?
500
Derived from or composed of any tissue involved in bone growth or repair (i.e. provides precursor cells that can differentiate into bone cells).
What is osteogenic?
