The diagnosis of fracture of the hook of the hamate is rarely made at the time of the initial injury. Routine roentgenograms of the hand in the standard three positions do not visualize this structure. The carpal tunnel view (CTV) with hyperextension of the wrist may be too painful to position. A computerized tomography of the wrist in the transverse or axial plane will clearly and painlessly identify the fracture. Placing both hands and wrists in the praying position gives excellent comparison and documents any developmental bone abnormality. Scintigraphy, when positive, must be followed by tomography or a carpal tunnel view.
钩骨钩骨折在初次受伤时很少能被诊断出来。手部标准三个位置的常规X线片无法显示该结构。手腕过度伸展的腕管位片（CTV）可能因摆位时过于疼痛而难以拍摄。手腕的横断位或轴位计算机断层扫描能清晰且无痛地识别骨折。将双手和手腕置于祈祷位可进行良好的对比，并记录任何发育性骨异常。骨闪烁显像呈阳性时，必须接着进行断层扫描或腕管位片检查。
