Herbert screw: The Herbert screw (invented by Timothy Herbert) is a variable pitch cannulated screw typically made from titanium for its stainless properties as the screw is normally intended to remain in the patient indefinitely. It became generally available in 1978.Internal fixationOsseointegration: Osseointegration derives from the Greek osteon, bone, and the Latin integrare, to make whole. The term refers to the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant.Cancellous bone: Cancellous bone, synonymous with trabecular bone or spongy bone, is one of two types of osseous tissue that form bones. The other osseous tissue type is cortical bone also called compact bone.X-ray microtomography: X-ray microtomography, like tomography and x-ray computed tomography, uses x-rays to create cross-sections of a physical object that can be used to recreate a virtual model (3D model) without destroying the original object. The prefix micro- (symbol: µ) is used to indicate that the pixel sizes of the cross-sections are in the micrometre range.Quantitative computed tomographyInterbody fusion cage: An interbody fusion cage (colloquially known as a "spine cage") is a prosthesis used in spinal fusion procedures to maintain foraminal height and decompression. They are cylindrical or square-shaped devices, and usually threaded.DeoxypyridinolineBone marrow suppression: Bone marrow suppression or myelotoxicity (adjective myelotoxic) or myelosuppression is the decrease in production of cells responsible for providing immunity (leukocytes), carrying oxygen (erythrocytes), and/or those responsible for normal blood clotting (thrombocytes). Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine.Bone tumorBone pathology: Bone pathology, also known as orthopedic pathology is a subspecialty of surgical pathology which deals with the diagnosis and feature of many bone diseases. It uses gross and microscopic findings along with the findings of in vivo radiological studies, and occasionally, specimen radiographs to diagnose diseases of the bones.Demineralized freeze dried bone allograft: Demineralized freeze dried bone allograft, referred to as DFDBA, is a bone graft material known for its [novo] bone formation properties.Bowers, GM, et al.Clay-shoveler fracture: Clay-shoveler's fracture is a stable fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae, classically at C6 or C7. In Australia in the 1930s, men digging deep ditches tossed clay 10 to 15 feet above their heads using long handled shovels.Chalkstick fracture: Chalkstick fractures are fractures, typically of long bones, in which the fracture is transverse to the long axis of the bone, like a broken stick of chalk. A healthy long bone typically breaks like a hard woody stick as the collagen in the matrix adds remarkable flexibility to the mineral and the energy can run up and down the growth rings of bone.Scoliosis Research SocietyCervical fractureCervical spine disorder: Cervical Spine Disorders are illnesses that are relatively detrimental to ones physical health. These ailments exist in the cervical spine which is made up of the upper first seven vertebrae, encasing and shielding the Spinal cord.Image-guided surgery: Today, doctors are using computerized technologies that are familiar to people in the consumer world to help fight cancer in the operating room. An important example of that application is image guided surgery (IGS) and it helps surgeons perform safer and less invasive procedures and remove brain tumors that were once considered inoperable due to their size and/or location.Bone Marrow Transplantation (journal): Bone Marrow Transplantation is a peer-reviewed medical journal covering transplantation of bone marrow in humans. It is published monthly by the Nature Publishing Group.Bone graftingHarrington Meeting HouseCurrarino syndrome: The Currarino syndrome (also Currarino triad) is an inherited congenital disorder where (1) the sacrum (the fused vertebrae forming the back of the pelvis) is not formed properly, (2) there is a mass in the presacral space in front of the sacrum, and (3) there are malformations of the anus or rectum. It can also cause an anterior meningocele or a presacral teratoma.Arcuate foramen: In human anatomy, arcuate foramen, also known as ponticulus posticus (Latin for "little posterior bridge"), refers to a bony bridge on the atlas (C1 vertebra) that covers the groove for the vertebral artery. It is a common anatomical variation and estimated to occur in approximately 3-15% of the population.Cement: A cement is a binder, a substance that sets and hardens and can bind other materials together. The word "cement" can be traced back to the Roman term opus caementicium, used to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder.Spinal fractureMechanochemistry: Mechanochemistry or mechanical chemistry is the coupling of mechanical and chemical phenomena on a molecular scale and includes mechanical breakage, chemical behaviour of mechanically stressed solids (e.g.Neuronavigation: Neuronavigation is the set of computer-assisted technologies used by neurosurgeons to guide or "navigate” within the confines of the skull or vertebral column during surgery, and used by psychiatrists to accurately target rTMS (Transcranial Magnetic Stimulation). The set of hardware for these purposes is referred to as a neuronavigator.Intramedullary rod
