Glossary of terms

Allograft:

A graft derived from tissue taken from another individual of the same species.

Alloplast:

Synthetically derived reconstructive material.

Anterior superior iliac spine:

The most anterior superior point of the ilium which gives attachment for the inguinal ligament and sartorius muscle.

Autograft:

A graft derived from tissue of the same individual.

Bone graft:

Bone material used to replace bone tissue in a defect.

Bone graft substitute:

A material other than bone used to replace bone tissue in a defect with the purpose of avoiding a donor site.

Graft:

Transferable material derived from living cells that can be surgically moved from one location to another for the purposes of reconstruction.

Iliac crest:

The superior most curved border of the fan-shaped ilium which connects the anterior to the posterior superior iliac spine and provides attachment as part of the insertion of the external oblique muscle.

Iliac tubercle:

A widening of the iliac crest at the insertion of the iliotibial band two to three centimetres posterior to the anterior superior iliac spine.

Osseointegration:

The formation of a direct bone to biomaterial interface without any interposed fibrous connective tissue.

Osteoconduction:

The ability to guide bone formation on the surface of a material or scaffold in a bony environment.

Osteogenesis:

The formation of new bone from osteocompetent cells.

Osteoinduction:

A process whereby one tissue or a product derived from it causes another undifferentiated tissue to differentiate into bone.

Posterior superior iliac spine:

A sharp spine which forms the posterior end of the iliac crest.

Xenograft:

Bone material or a graft derived from an individual of a different species.
