Intrasound vibration in the early diagnosis of scaphoid fracture.

A prospective trial was designed to assess the sensitivity and specificity of intrasound vibration for the early detection of scaphoid fracture. We replicated the method described by Finkenburg et al. (J Hand Surg 1993;18A:4-7) in an attempt to corroborate their results. We found the test to be 73% sensitive and 51% specific. Because the test was not 100% sensitive, as claimed by Finkenburg et al., we discontinued the use of this device in our hospital.
