The minimal distance Between fracture lines and screws when using /screw construct is…
4-5mm or equal to the diameter of the screw used
The ideal plate size is _____ of the length of the bone
Just short
VCP plates stands for…
Veterinary cuttable plates
LCDCP plates can have screws angles up to ___ degrees due to the hole design.
40 degrees
Plate pin systems increase fatigue life by___ and stress reduction by ____ when compared to plates alone.
10 fold and 2 fold
What is osteogenesis?
A graph that supplies and supports bone forming cells. Bone formation requires the cellular machinery to fabricate its structural components
What is osteoinduction?
Materials that have the capacity to induce bone formation when placed into a site where no bone formation will occur these materials recruitment single stem cells or their project infiltrate material of tissues and induce multipotential cells to multiply and become cells that make up regenerating bone Callus
What is Osteocondjction?
Material that provide a scaffold for the mesenchymal stems cells and their progeny to migrate into and proliferate within
Bridging osteosynthesis
Early callus formation is responsible for much of the stabilization. Fixation must be only
Nonunion types
Viable Hypertrophic Moderately hypertrophic Oligotrophic Non viable Dystrophic Necrotic Defect Atrophic
Diartheoidal
Any of several types of bone articulation permitting free motion in a joint, as that of the shoulder or hip. With synovium
Amphiarthrosis
Cartilaginous joints these joints of limited motion which permits compression stretching. Fibrocartilage mandibular symphysis
Synchondrosis
Hyaline cartilage joint

Osteosarcoma
Codmans triangle
Periosteal new bone formation under an elevated cortical bone at a lesions periphery that creates a triangle appearance. Can be seen with osteosarcoma but is not pathognomonic.
