The purpose of this study was to assess the relationships between the pattern of fractures and associated intra-articular soft tissue injuries. MATERIALS AND
METHODS:
We performed a study of 31 patients treated for distal radius fracture. Radiographic evaluation included ulnar styloid process fracture, dorsal anglulation and ulnar variance. We observed TFCC injuries, scapholunate and lunotriquetral ligamentinjuries by arthroscopy.
RESULTS:
The incidence of TFCC radial rim tear and lunotriquetral ligamentinjuries were significantly higher in die punch fractures with lunate facet involvement than in fractures without lunate facet involvement (p0.05).
CONCLUSION:
The TFCC radial rim and the lunotriquetral ligament may be injured by axial compression loading of the ulnar head on the triquetrum. TFCC radial rim tear and lunotriquetral ligamentinjuries must be kept in mind in die punch fractures with lunate facet involvement.
