Revision to "X-rays" section
[edit]I am proposing the removal of the SLAC and SNAC headings from the X-Ray section and the addition of new edits. The section currently reads:
"X-rays
Radiographs can confirm the diagnosis of wrist osteoarthritis. The earliest sign is narrowing of the joint space between the radius and the scaphoid and an osteophyte off the tip of the radial styloid.
SLAC
Further information: Scapholunate ligament
Because SLAC results from scapholunate ligament rupture, there is a larger space between the two bones, also known as the Terry Thomas sign. 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 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. Computed tomography (CT) or Magnetic Resonance Imaging (MRI) are rarely used to diagnose SNAC or SLAC wrist osteoarthritis 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."
The edited version will read as follows:
"X-rays
Radiographs can confirm the diagnosis of wrist osteoarthritis. The earliest sign is narrowing of the joint space between the radius and the scaphoid and an osteophyte off the tip of the radial styloid.[10]
Because SLAC results from scapholunate ligament rupture, there is a larger space between the two bones, also known as the Terry Thomas sign.[11] In SNAC, the space between the proximal pole of the scaphoid and the distal radius is relatively preserved."
Reasoning: Much of the information in the SLAC paragraph is not relevant on an osteoarthritis page. Additionally, the differences between SLAC and SNAC are minor. Other type of imaging are not helpful. Unecomeditor1 (talk) 14:01, 11 October 2023 (UTC)
