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...

Proprioceptive information about movement is transmitted to the central nervous system by a variety of receptor types, which are widely distributed among the muscles, joints, and skin. Muscle spindles are known to be an important and reliable source of information for the perception of movement kinematics. Previous studies that focused on the characteristics of single muscle spindle firing patt...

The majority of distal radius fractures are associated with an ulnar styloid fracture [1-3]. There is solid evidence in the literature that this association may ultimately affect the clinical outcome causing instability, disability, and pain in the distal radioulnar joint (DRUJ) [2,4-7]. The main reasons for the worse outcome are: (1) DRUJ instability, (2) impingement with the triquetrum, and (...

Extreme self-neglect is a problem amongst a small but significant proportion of the population. The hand surgeon encounters cases of acute digital ischemia with a wide spectrum of aetiologies. These include thrombosis, trauma and iatrogenic causes.1 A hoarding disorder is characterised by an individual who acquires an excessive number of items and stores them in a chaotic manner.2 Hoarding is a...
