Abstract:
We present two coronal fractures of the proximal scaphoid which were both missed in the acute stage as interpretation of initial radiographs was difficult. In both cases, recognition of the so-called "Proximal Ring Sign" on the PA ulnar deviation radiographs may have helped diagnosis. CT scans were necessary to fully demonstrate the fractures. Open reduction and internal fixation, performed 2 and 4 months after the injury, resulted in union in both cases.
