The mechanical effect of a muscle following agonist-to-antagonist tendon transfers does not always meet the surgeon's expectations. We tested the hypothesis that after flexor carpi ulnaris (FCU) to extensor carpi radialis (ECR) tendon transfer in the rat, the direction (flexion or extension) of the muscle's joint moment is dependent on joint angle. Five weeks after recovery from surgery (tendon...

OBJECTIVE The aim of this study was to investigate and compare the conduction parameters of nerve bundles of median and ulnar nerves that innervate proximal and distal muscles. SUBJECTS AND METHODS Thirty male and 30 female healthy volunteers between 18 and 70 years of age were enrolled in the study. The conduction parameters were recorded from the proximally located flexor carpi ulnaris, pro...

A rare case of closed, non-rheumatoid rupture of the extensor carpi ulnaris tendon, that occurred in a professional tennis player, is presented. The authors describe the diagnostic problems and the treatment. They discuss the anatomical particularities of the area, the probable pathological mechanisms that lead to the lesion and the best ways of dealing with the problem.
