1
Q

Osteoconductive

A

Provides a natural scaffold for new bone formation (doesn’t cause osteogenesis though, only aids). Usually used in reference to bone graft.

Q

Osteoinductive

A

Osteoinduction is the process by which osteogenesis is induced. Osteoinduction implies the recruitment of immature cells and the stimulation of these cells to develop into preosteoblasts.

Q

Allograft bone

A

A tissue graft used during surgery that is taken from someone other than the patient being operated on, usually from a cadaver or a bone bank.

Problems: by itself it is only osteoconductive, not osteoinductive. Needs something like stem cells or bmp to cause bone cell growth.

Q

Autograft

A

Bone graft which is created from taking bone from one location in an individual (ileum of pelvis usually) and placed in another in the same individual.

Problems: extra surgery time & usually means multiple incisions = more chance for complications, infections and longer recovery.
