Three-dimensional CT imaging in the evaluation of flexor tendon ruptures in the hand and wrist

The purpose of this study was to determine the usefulness of 3D CT imaging in the diagnosis of flexor tendon ruptures in the hand and wrist. Eighteen hands (15 adults, 3 children) with a spectrum of finger flexion disturbances were investigated by a multidetector-row CT scanner, and diagnosed by 3D CT image with the volume rendering technique. Three-dimensional CT images clearly depicted the location of rupture and tendon stumps in all adult-cases. In two of three child-cases, the image analysis was equivocal. We found 3D CT imaging to be an excellent procedure in the investigation and diagnosis of flexor tendon rupture in adult-cases. Three-dimensional CT imaging can be useful when the diagnosis of flexor tendon rupture can not be made based on trauma history and clinical examinations, and can be helpful in surgical planning.
