Periosteal

Periosteal: Pertaining to the periosteum, a dense membrane composed of fibrous connective tissue that closely wraps (invests) all bone, except the bone of articulating surfaces in joints which are covered by synovial membranes. Peri- is a prefix borrowed from the Greek meaning "around or about" and "-osteal" also comes from the Greek, from "osteon" meaning "bone" so periosteal literally pertains to around bone.
