Malunion of the ulnar styloid as a cause of ulnar wrist pain

Abstract

We present a case of ulnar wrist pain that had been wrongly attributed to non-union of the ulnar styloid. Surgical exploration revealed an ulnar styloid malunion that had caused pain by impinging on the triquetrum and a triangular fibrocartilage complex (TFC) lesion. There was no fracture of the distal radius and no associated carpal instability or disruption of the distal radio-ulnar joint. Treatment by resection of the ulnar styloid and re-attachment of the TFC provided a satisfactory outcome.

Pain After Median Sternotomy: Collateral Damage or Mitigatable Byproduct?

“…The relationship between misalignment of bone and pain was suggested in the patients with malunion in clavicle or ulnar fractures. 14,15 Therefore, we can postulate that the sternal pain after median sternotomy originates from the damaged periosteum, not the divided bone itself.…”

The management of distal ulnar fractures in adults: a review of the literature and recommendations for treatment

“…There are a number of reasons why a non-united ulnar styloid fracture can become symptomatic: It can be responsible for a non-functioning ulno-radial ligament (peripheral TFCC detachment) [27] (Fig. 6), cause impingement of the overlying ECU tendon [28], abut on the carpus [27, 29] (Fig. 7) or be an irritative loose body [27] (Fig.…”
