Ulnar Styloid Fracture ICD-9

  • 813.43 Fracture of distal end of ulna; head lower end lower epiphysis styloid process

Ulnar Styloid Fracture Etiology / Epidemiology / Natural History

  • Commonly associated with distal radius fracture

Ulnar Styloid Fracture Anatomy

  •  Large ulnar styloid fractures include at least part fo the origin of the triangular fibrocartilage complex and may lead to radioulnar instability.

Ulnar Styloid Fracture Clinical Evaluation

  • Ulnar sided wrist pain and swelling.

Ulnar Styloid Fracture Xray / Diagnositc Tests

Ulnar Styloid Fracture Classification / Treatment

  • Nondisplaced
  • Displaced: involves >50% of the length of the styloid or displaced >2mm associated with DRUJ instability. (May MM, J Hand Surg 2002;27Am:965) Treatment = ORIF vs CRPP (k-wire, tension band, intraosseous suture)
  • Nonunion: Type-1 (DRUJ stable) =fracture through the tip of the styloid, treated with excision if symptomatic. Type-2(DRUJ unstable) = fracture through the base of the styloid, treated with ORIF and TFCC repair.( Hauck RM J Hand Surg 1996;21Am:418)
  • With associated distal radius fracture: unrepaired ulnar styloid fracture, even if displaced >2mm, does not influence function or outcome after ORIF of distal radius fractures (Souer JS, JBJS 2009;91A:830)
