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.Assay sensitivity: Assay sensitivity is a property of a clinical trial defined as the ability of a trial to distinguish an effective treatment from a less effective or ineffective intervention. Without assay sensitivity, a trial is not internally valid and is not capable of comparing the efficacy of two interventions.Cancer survival rates: Cancer survival rates vary by the type of cancer, stage at diagnosis, treatment given and many other factors, including country. In general survival rates are improving, although more so for some cancers than others.ProstatectomyList of eponymous surgical procedures: Eponymous surgical procedures are generally named after the surgeon or surgeons who performed or reported them first.

The OKS has subsequently been validated for use in assessing other non-surgical therapies applied to those suffering from issues with the knee.Cardiopulmonary bypassOsteotomyEsophagectomyLymphovascular invasionInterbody 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.Spinal decompression: Spinal decompression is the relief of pressure on one or many pinched nerves (neural impingement) of the spinal column.Scoliosis Research SocietyMinimally invasive hip resurfacing: Minimally invasive hip resurfacing (MIS) is "total or partial hip surgery that can be carried out through an incision of less than 10 cm (3.94 inches) without imparting great forces on the anatomy or compromising component positioning"Comis Orthopaedics websiteLogMAR chart: A LogMAR chart comprises rows of letters and is used by ophthalmologists and vision scientists to estimate visual acuity. This chart was developed at the National Vision Research Institute of Australia in 1976, and is designed to enable a more accurate estimate of acuity as compared to other charts (e.Lung cancer surgery: Lung cancer surgery describes the use of surgical operations in the treatment of lung cancer. It involves the surgical excision of cancer tissue from the lung.Diffuse lamellar keratitis: Diffuse lamellar keratitis (DLK) is a sterile inflammation of the cornea which may occur after refractive surgery, such as LASIK. Its incidence has been estimated to be 1 in 500 patients, though this may be as high as 32% in some cases.Abdominal aortic aneurysmBreast biopsyRotational angiography: Rotational angiography is a medical imaging technique based on x-ray, that allows to acquire CT-like 3D volumes during hybrid surgery or during a catheter intervention using a fixed C-Arm. The fixed C-Arm thereby rotates around the patient and acquires a series of x-ray images that are then reconstructed through software algorithms into a 3D image.Anesthesia cart: Anesthesia carts are hospital devices used to store tools that are necessary for aid during procedures that require administration of anesthesia. Anesthesia refers to the use of drugs to subdue a patient's mind and prevent him or her from feeling any pain during a surgical operation.Carcinoembryonic antigen: Carcinoembryonic antigen (CEA) describes a set of highly related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth.Optimax: Optimax is a UK-based laser eye treatment specialist which has 38 locations nationwide. Optimax was established as one of the first private clinics to offer laser eye surgery.Metastatic liver disease: A liver metastasis is a malignant tumor in the liver that has spread from another organ affected by cancer. The liver is a common site for metastatic disease because of its rich, dual blood supply (the liver receives blood via the hepatic artery and portal vein).PinnacleHealth System: $1 billion (2013)Journal of Minimal Access Surgery: Journal of Minimal Access Surgery (ISSN: Print - 0972-9941, Online - 1998-3921) is peer-reviewed open access journal published on behalf of the Indian Association of Gastrointestinal Endo Surgeons.

In Australia in the 1930s, men digging deep ditches tossed clay 10 to 15 feet above their heads using long handled shovels.Autologous blood injection: Autologous Blood Injection (ABI), also known as Autologous Conditioned Plasma (ACP) Injection is a recent medical procedure whereby a patient's blood is injected into an area of the body for the purposes of healing. It is most commonly used to treat degeneration of tendons, which may occur in association with small tears.Pain scale: A pain scale measures a patient's pain intensity or other features. Pain scales are based on self-report, observational (behavioral), or physiological data.Drainage system (agriculture): An agricultural drainage system is a system by which the water level on or in the soil is controlled to enhance agricultural crop production.Cataract surgeryTransverse folds of rectum: The transverse folds of rectum (or Houston's valves) are semi-lunar transverse folds of the rectal wall that protrude into the rectum, not the anal canal as that lies below the rectum. Their use seems to be to support the weight of fecal matter, and prevent its urging toward the anus, which would produce a strong urge to defecate.Ophthalmic Viscosurgical Device: Ophthalmic Viscosurgical Device (OVD) is viscoelastic solution used in eye surgery also referred to as viscoelastic agents. Their introduction has had a profound influence on the evolution of extracapsular and phacoemulsification surgery, and their use has decreased the incidence of corneal edema as aNeuronavigation: 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).
