Wrist arthroplasty
Wrist arthroplasty, also called total wrist arthroplasty (TWA), is a surgical procedure that replaces the arthritic wrist joint with an artificial implant, relieving pain while preserving some motion.
Wrist arthroscopy
Wrist arthroscopy is a minimally invasive procedure using a small camera inside the wrist joint to diagnose and treat conditions like TFCC tears and fractures.
WSL-Curodont trial
The WSL-Curodont trials are randomized controlled trials testing topical P11-4 (Curodont Repair), a self-assembling peptide that promotes remineralization, against fluoride varnish, placebo, or no treatment for arresting white spot lesions.
X-Ray Film
X-ray film: silver halide emulsion on a polyester base, used with intensifying screens as the classic radiographic image receptor; 8–12 line pairs/mm resolution, limited dynamic range, now largely replaced by digital detectors.
X-Ray Intensifying Screens
X-ray intensifying screens are fluorescent phosphor sheets in film cassettes that convert X-rays to visible light, cutting patient dose. Calcium tungstate dominated from 1896 until rare-earth phosphors arrived in the 1970s.
X-ray luminescence computed tomography
X-ray luminescence computed tomography (XLCT) is a hybrid imaging method, reported by Guillem Pratx and colleagues in 2010, that maps x-ray-excited luminescent nanoparticles inside an object from surface optical measurements.

Xenodiagnosis
Xenodiagnosis is a diagnostic method in which laboratory-reared triatomine bugs feed on a patient's blood and are later examined for Trypanosoma cruzi, mainly to confirm chronic Chagas disease.
Xenotransfusion
Xenotransfusion is the transfusion of blood or blood products from another species into a human patient, investigated to relieve blood shortages, particularly in emergency settings.
Xenotransplantation
Xenotransplantation, also called heterologous transplantation, is the transfer of living cells, tissues, or organs from nonhuman animals, chiefly pigs, into human patients to ease the organ shortage.
Xeromammography
Xeromammography is xeroradiography of the breast, a filmless electrostatic X-ray method using selenium plates and dry toner, commercialized by Xerox around 1970-1971, widely used in the 1970s, and replaced by screen-film and digital mammography.
Xeroradiography
Xeroradiography is a dry electrostatic method for recording X-ray images using a selenium-coated plate and charged powder toner. It was widely used in mammography in the 1970s.
Xpert MTB/RIF assay
The Xpert MTB/RIF assay is an automated cartridge-based molecular test that detects tuberculosis DNA and rifampicin resistance directly from unprocessed sputum in under two hours, endorsed by WHO in 2010.
Y-balance test
The Y-balance test is a low-cost field test of dynamic balance in which a person balances on one leg and reaches with the other in three directions.
