High frequence sonography of the hand by means of an ophthalmologic standard sonography equipment

W. Schmidt

Background: Conventional radiology , MRT and CT are approved methods for examination of the hand. In our study we examined the use of middle- and high-frequence-sonography for the examination of the hand by means of an ophthalmologic standard apparates.

Methods: For the sonographic examination of the hand we used the I3 sonography instrumentation (Innovative Imaging Inc., Sacramento, USA). The frequence of the transducers is 10 or 20MHz. The examination is performed in a water bath. We examined the contour of the end-, middle-, and ground phalanx as well as the metacarpalia.

Results: The articulating surfaces of the bones of the hand can be clearly detected. The continuity of the extensor- and flexor- tendons can be detected by means of 10MHz sonography. In addition high frequence sonography demonstrates the exact arrangement of the structure of the fibers within the tendons. In addition the muscles of the hand can be examined.

Discussion: The middle and high frequence sonography of the hand allows the examination of bones, joints, and muscles of the hand. Our first results point out that the high frequence sonography of the hand is a complementary tool for the examination of degenerative, traumatic or rheumatic diseases of the hand.
