Radial styloidectomy is a procedure that involves removal of radial styloid. It is a kind of salvage procedure which aims to reduce pain arising from radial styoid impingement that that may occur in scaphoid nonunion or scapholunate instability.
It may not be a definitive treatment though.
Radial styloidectomy is an acceptable alternative to more aggressive procedures in patients with low functional demands or those who wish to defer more definitive treatment.
Radial styloidectomy is contraindicated in patients with ulnar translocation of carpus.
It is a kind of palliative procedure. This suits to the patients who want minimum surgical intervention. It however, rarely address the underlying cause. It can be done either as open procedure or arthroscopic procedure. Arthroscopy has the advantage of less surgical dissection, less postoperative pain, faster recovery.
- Radial styloid impingement in scapholunate instability or scphoid fractures
- Secondary radial styloid impingement as a sequelae of scaphotrapeziotrapezoidal fusion. Some authors recommend radial syloidectomy at the time of procedure.
Patients with painful radial deviation and positive Watson test are ideal candidates.
Radial styloidecomy can be used as adjunct to other salvage procedure like proximal row carpectomy.
The amount of radial styloid to be excised is determined by peroperative examination
