<unk>  of the<unk>  is predominantly a clinical diagnosis, and thus is primarily based on the patients medical history, physical examination and<unk>  X-rays. Medical history Medical history of the patient should include age, hand dominance, occupation and most important an evaluation of recent hand traumas. Physical examination Examination will often show tenderness at the radioscaphoid joint (when palpated or while moving the radioscaphoid joint), dorsal radial swelling and instability of the<unk>  joint. Notice that people may say they have trouble with rising from a chair when pressure is exerted on the hands by pushing against the handrail. Younger people may complain about not being able to do push-ups anymore because of a painful hand. There are a number of tests and actions that can be performed when a patient is suspected of having<unk>  caused by SLAC or SNAC. SLAC: * Tenderness 1 cm above Lister’s tubercle Tests: * Watson's test * Finger extension test SNAC: * Tenderness at the anatomical snuff box * Painful pronation and supination when performed against resistance * Pain during axial pressure X-rays<unk>  between the radius bone and the carpals is indicated by a radiocarpal joint space of less than 2mm. SLAC Because SLAC results from scapholunate ligament rupture, there is a larger space between the two bones, also known as the Terry Thomas sign.<unk>  and a space larger than 3 mm is suspicious and a space larger than 5 mm is a proven SLAC pathology. Scaphoid instability due to the ligament rupture can be stactic or dynamic. When the X-ray is diagnostic and there is a convincing Terry Thomas sign it is a static scaphoid instability. When the scaphoid is made unstable by either the patient or by manipulation by the examining physician it is a dynamic instability. SNAC In order to diagnose a SNAC<unk>  you need a PA view X-ray and a lateral view X-ray. As in SLAC, the lateral view X-ray is performed to see if there is a DISI. Computed tomography (CT) or Magnetic Resonance Imaging (MRI) are rarely used to diagnose SNAC or SLAC<unk>  because there is no additional value. Also, these techniques are much more expensive than a standard X-ray. CT or MRI may be used if there is a strong suspicion for another underlying pathology or disease.
