In order to diagnose a SNAC wrist 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. [12] Computed tomography (CT) or Magnetic Resonance Imaging (MRI) are rarely used to diagnose SNAC or SLAC wrist osteoarthritis because there is no additional value. [7]
Symptoms of radial neuropathy vary depending on the severity of the trauma; however, common symptoms may include wrist drop, numbness on the back of the hand and wrist, and inability to voluntarily straighten the fingers. Loss of wrist extension is due to loss of the ability to move of the posterior compartment of forearm muscles.
The differential diagnosis includes scaphoid fractures and wrist dislocations, which can also co-exist with a distal radius fracture. Occasionally, fractures may not be seen on X-rays immediately after the injury. Delayed X-rays, X-ray computed tomography (CT scan), or Magnetic resonance imaging (MRI) can confirm the diagnosis.

SLAC wrist is the most common type of post-traumatic wrist osteoarthritis [1] and is often the result of an undiagnosed or untreated scapholunate ligament rupture. [2] The condition follows a predictable pattern of development, which was first described by H. Kirk Watson, M.D. and Frederick L. Ballet, M.D. in 1984.
In radiology, the Terry-Thomas sign is a scapholunate ligament dissociation on an anteroposterior view of the wrist. [1] [2] Most commonly a result of a fall on the outstretched hand , the scapholunate ligament ruptures resulting in separation of the lunate and scaphoid bones. This burst causes the scaphoid bone to dorsally rotate. [3]
Apart from cardiac MRI other real-time applications deal with functional studies of joint kinetics (e.g., temporomandibular joint, [30] knee and the wrist [31]) or address the coordinated dynamics of the articulators such as lips, tongue, soft palate and vocal folds during speaking (articulatory phonetics) [32] or swallowing. [33]
MRI: is, together with the findings of a careful physical examination, a helpful diagnostic tool to assess the condition of the TFCC. Nevertheless, the incidence of false-positive and false-negative MRI results is high. [2] Arthrography: a dye is injected into the wrist joint. If there is a TFCC lesion the dye will leak from one joint ...
Kienböck's disease is a disorder of the wrist.It is named for Dr. Robert Kienböck, a radiologist in Vienna, Austria who described osteomalacia of the lunate in 1910. [1]It is breakdown of the lunate bone, a carpal bone in the wrist that articulates with the radius in the forearm.
