	Periosteum - Wikipedia, the free encyclopedia
		The periosteum is an envelope of fibrous connective tissue that is wrapped around the bone in all places except at joints (which are protected by cartilage).
		The periosteum is connected to the bone by strong collagenous fibers called Sharpey's fibres, which extend to the outer circumferential and interstitial lamellae of bone.
		The "pericranium" is the periosteum of the skull.

	Medical Massage, pp. 80 - 84
		In the diaphysises of long bones, the periosteum has a thickness of about 2-3 millimeters, with a gradual decrease of thickness in the metaphysises and connecting to the cartilage in the epiphyses.
		The periosteum is richly innervated and through it pass the blood vessels that feed the bone.
		Abnormalities in the periosteum are represented either by local pain or by the changing structure of the periosteum.

		Once the periosteal site has been prepared, a rectangular area of periosteum is outlined that is 2 mm wider and longer than the measured prepared defect in the cartilage.
		Elevation of the periosteum should proceed from distal to proximal and care must be used not to damage the cambium layer of the periosteum.
		The periosteum is sewn to the periphery of the cartilage using fine 6-0 absorbable suture.

		(Periosteum is essentially the bone’s epimysium —deep fascia of the bone.) Endosteum is the connective tissue that lines the surface of bony spicules.
		The space between the periosteum (the part that lines the inside of the vertebra) and the outer surface of the dura is the epidural space.
		Unlike the dura of the spinal cord, the dura of the brain is adherent to the endocranium of the periosteum.

	Encyclopedia
		Numerous experiments show that the formation of bone is essentially due to the action of the periosteum and that, by transplanting detached portions of periosteum into muscular or other tissues, bony tissue is generated in those parts.
		It appears to be the curative agent in the case of bone breakage.
		In most cases in which the periosteum has become detached as a result of a wound or of disease, the exposed bone perishes (except in the instance of the skull, which derives most of its nutrient matter from the dura mater, actually the periosteum of the inner surface of the skull).

	PERIOSTEUM: ITS BIOMECHANICAL ROLE IN BONE FRACTURE (Site not responding. Last check: 2007-10-31)
		The periosteum is a layer of dense fibrous connective tissue which surrounds the external surface of most bones.
		For normal ribs (with the periosteum), the maximum deformation and the total energy absorbed were 2.73 cm and 63.6 kg·cm respectively.
		Therefore, it is reasonable to assume that the periosteum resists part of the tension imposed on the cortex and thus, contributes to increased resistance of a bone fractured by bending.

		The periosteum is a membrane several cell layers thick that covers almost all of every bone.
		Well, the periosteum is a fairly promiscuous tissue, and puts on a similar response to all comers.
		When a process is growing too fast for the periosteum to respond with even thin shells of new bone, sometimes only the edges of the raised periosteum will ossify.

	Abstract: Gene Marking in Adeno-Associated Virus Vector Infected Periosteum Derived Cells for Cartilage Repair
		Periosteum was obtained from the tibia of 6-week-old rabbits and enzymatically digested.
		The isolated periosteum derived cells were cultured and the subconfluence cells were infected with a recombinant AAV expressing the LacZ gene (AAV-LacZ).
		Gene expression in periosteum derived cells was sustained in vitro for at least 12 weeks using the AAV vector, and for 2 weeks ex vivo after transplantation into a cartilage defect.

		The principle obstacle to overcome for the use of periosteal tissue grafts for tissue engineering is the declining cartilage growth potential of periosteum with increasing age of the patient.
		We are examining the potential for pretreatment of periosteum with known cartilage-inducing growth factors to enhance (1) the number of chondrogenic precursor cells in periosteum in vivo, (2) the in vitro cartilage growth potential of periosteum and (3) the potential of periosteum to repair articular cartilage defects.
		However, the mechanisms by which undifferentiated mesenchymal cells in periosteum detect their mechanical environment, and the cascade of events that eventually result in production of cartilage are unknown.

	Systems for securing sutures, grafts and soft tissue to bone and periosteum (US6200330)
		In a first embodiment, the invention comprises a piton member implantable within bone having a post or eyelet formed thereon to which the suture or tissue may be attached.
		The piton member is designed to become more firmly secured within the bone when pressure is applied to a first axis pushing the piton member into the bone, but may be easily removed when such force is applied in a generally opposed direction.
		In a second embodiment, the invention comprises affixation devices that are designed to detachably ensnare with periosteum.

		In 11 patients (1 with prior repair), the torsion was corrected by suturing the lateral edge of the corpus cavernosum to the pubic periosteum (study group).
		They found that lateral suturing of tunica albuginea to the pubic periosteum to repair penile torsion appeared to be a better technique in their hands.
		They were able to adjust the correcting angle during the operation and achieve a complete and accurate correction of the rotation.
