Eine computertomographische Methode zur Bestimmung der Tibiatorsion

A computer tomographic method is described for measuring tibial torsion in vivo. The basis of the method depends on transverse scans of the tibia through the knee and ankle joint region by means of which it is possible to establish normal values and abnormal posttraumatic or in congenital torsion. Traumatologists, as well as orthopaedic surgeons, require reproducible measurements, since a detorsion operation may rectify deformities which would lead to degenerative joint changes. A review of previously available methods with torsiometer or conventional radiography shows the limitations of these methods.
