There are a number of tests and actions that can be performed when a patient is suspected of having osteoarthritis caused by SLAC or SNAC.SLAC:

Tenderness 1 cm above Lister’s tubercleTests:

Watsons test
Finger extension testSNAC:

Tenderness at the anatomical snuff box
Painful pronation and supination when performed against resistance
Pain during axial pressure

X-rays
Osteoarthritis 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. Osteoarthritis 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 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.
Sarcoma botryoides or botryoid sarcoma is a subtype of embryonal rhabdomyosarcoma, that can be observed in the walls of hollow, mucosa lined structures such as the nasopharynx, common bile duct, urinary bladder of infants and young children or the vagina in females, typically younger than age 8. The name comes from the gross appearance of "grape bunches" (botryoid in Greek). Presentation
For botryoid rhabdomyosarcoma of the vagina, the most common clinical finding is vaginal bleeding but vaginal bleeding is not specific for sarcoma botryoides:  other vaginal cancers are possible. They may appear as a polypoid mass, somewhat yellow in color and are friable: thus, they (possibly) may break off, leading to vaginal bleeding or infections. Histology
Under the microscope one can see rhabdomyoblasts that may contain cross-striations. Tumor cells are crowded in a distinct layer beneath the vaginal epithelium (cambium layer). Spindle-shaped tumor cells that are desmin positive. Treatment
The disease used to be uniformly fatal, with a 5-year survival rate between 10 and 35%. As a result, treatment was radical surgery. New multidrug chemotherapy regimens with or without radiation therapy are now used in combination with less radical surgery with good results, although outcome data are not yet available. Epidemiology
Sarcoma botryoides normally is found in children under 8 years of age. Onset of symptoms occurs at age 3 years (38.3 months) on average. Cases of older women with this condition have also been reported. References
