Ulnar styloid impaction syndrome
Updates to Article Attributes
Ulnar styloid impaction syndrome refers to wrist pain due to a long ulnar styloid process impacting upon the triquetral bone.
Pathology
An unlar styloid greater than 6 mm :, i.e. the proximal pole of the triquetral bone and ulnar styloid tip.
Chronic impaction can lead to lunotriquetral instability. The triangular fibrocartilage(TFC) complex (TFCC) is usually intact.
Treatment and prognosis
Surgical removal of the ulnar styloid process can effectively treat the condition.
Differential diagnosis
A similar but distinct impaction syndrome due tonon non-union of the ulnar styloid(commonly following fracture) can also occur. This syndrome more commonly involves disruption of the TFCTFCC complex.
