The objective of this study was to assess the effects of asymmetric placement of the foot on the three-dimensional motions of the interphalangeal joints. Four isolated forelimbs were used. Trihedrons, made of three axes fitted with reflective markers, were screwed into each phalanx. They allowed to establish a local frame associated with each bone and thus to define the spatial orientation of t...

PURPOSE Regaining hand function has been identified as the highest priority for persons with tetraplegia. In many patients, finger flexion can be restored with a tendon transfer of extensor carpi radialis longus to flexor digitorum profundus (FDP). In the absence of intrinsic function, this results in a roll-up finger movement, which tends to push large objects out of grasp. To enable patients ...

Injuries about the PIP joint of the finger are commonly encountered by primary care physicians and are associated with significant morbidity, including pain, stiffness, instability, premature degenerative arthritis, and residual deformities. An accurate understanding of the regional anatomy and appreciation of the mechanism of injury allows for classification so that a treatment protocol can be...

Fractures of the phalanges of the fingers are common injuries. The average accident and emergency department will see several hundred each year (Benke & Stableforth, 1979). Causal factors include falls, road traffic accidents and commonly sport, especially football and cricket (Barton, 1977). About 18% of all phalangeal fractures extend into a joint, usually the proximal interphalangeal joint a...

Fracture-dislocations of the proximal interphalangeal joint encompass a spectrum of injury severity, ranging from injuries that require little intervention to those that require advanced reconstructive surgery for optimal outcome. Three fracture-dislocation patterns are recognized: dorsal, volar, and pilon. Acceptable outcome is dependent on achieving and maintaining a well-aligned and well-red...

BACKGROUND Surface replacement arthroplasty is a reconstructive alternative for the treatment of pain and deformity due to osteoarthritis and rheumatoid arthritis of the proximal interphalangeal joint of the finger. This retrospective study was performed to examine long-term outcomes of proximal interphalangeal joint prosthetic surface replacement with a proximal cobalt-chromium (CoCr) and dist...
