Excerpt
A 33-year-old man was admitted in the emergency room after sustaining a minor traumatic event on the left wrist. The patient presented pain and tenderness at the wrist, which was more intense in the anatomic snuffbox area. Radiographic study showed a well-defined lithic lesion in the proximal third of the scaphoid, consistent with intraosseous ganglion, with a fracture line across it (Fig. 1). Computed tomographic scan confirmed the diagnosis of pathologic fracture of the scaphoid, without displacement, caused by a lithic lesion (Fig. 2). The fracture was treated with a below-elbow cast for 8 weeks. Follow-up radiographic studies showed the progressive obliteration of the bone defect and healing of the fracture (Fig. 3). A computed tomographic scan of the fracture obtained after 9 weeks revealed filling of the cavity and healing of the fracture (Fig. 4). In the last control, 12 months after injury, the patient presented discomfort only in intense effort, with free joint movement and a grip strength symmetric to the contralateral hand, and normal radiograph with complete disappearance of the lithic lesion (Fig. 5).
