The debatable relationship of functional human hand proportion with the Fibonacci series has remained an obscure scientific enigma short of clinical interest. The main difficulty of proving such a relationship lies in defining what should constitute true functional proportion. In this study, we re-evaluate this unique relationship using hand flexion creases as anatomical surrogates for the...

Fifteen patients underwent arthrodesis of finger distal interphalangeal joint (DIP) and/or thumb interphalangeal joint (IP). Only Herbert screw intramedullary compression fixation was used. There was one faulty proximal thread placement with some pain, but the patient refused further surgery. Full union was achieved in 14 of the cases, with prominent hardware in one and intolerance to cold in two.

Psoriatic arthritis has now gained general acceptance as an entity distinct from rheumatoid disease (Garrod and Evans, 1924; McEwen, Ziff, Carmel, DiTata, and Tanner, 1958; Wright, 1961). Distal interphalangeal joint involvement is a prominent feature of psoriatic arthritis (Avila, Pugh, Slocumb, and Winkelmann, 1960; Bauer, Bennett, and Zeller, 1941; Sherman, 1952), but not of rheumatoid arthr...

INTRODUCTION An understanding of abnormal finger motion depends on a basic knowledge of normal functional anatomy, which can be found in the contributions made by Eyler and Markee (! 954), Kaplan (! 953), Milford (! 968), Stack (! 962), Tubiana and Valeillin (1963). It is then possible to appreciate that the finger is a combination of two biarticular, bimuscular ~ystems: a proximal system consi...

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 ...

BACKGROUND Sports-related open lateral collateral ligament injury of the interphalangeal joint of the great toe has not been previously described in the English literature. HYPOTHESIS This injury can occur in adolescents while performing barefooted high-kicking or fast-running exercises involving rapid, 180 degrees turns on a dry, rough, wooden floor in a Taekwondo gymnasium. Injury occurs wh...

We reviewed 13 patients with a complex fracture-dislocation of the proximal interphalangeal joint of a finger and one patient with a complex fracture-dislocation of the interphalangeal joint of thumb. We had treated these injuries using a pins and rubbers traction system which had been modified to avoid friction of the pins against the bone during mobilisation of the joint in order to minimise ...
