[Coronal fractures of scaphoid].

Two cases of frontal fracture of the scaphoid proximal pole after a high energy trauma are reported. Diagnosis was delayed in both cases and was only possible with a CT-scan. One fracture was slightly displaced: the patient was treated conservatively and followed during 11 years with an excellent result. The other patient was operated on because of persistent pain and malunion. Only during surgery was the correct diagnosis made and due to scaphoid malunion, a proximal row carpectomy was performed. At a post operative assessment, in both cases, X-rays showed a double contour of the proximal pole of the scaphoid. We believe than an arthroCT-scan or MRI is necessary to assess the fracture displacement and search for an associated ligamentous injury.
