A new form of microprocessor-controlled arthrograph is described which measures stiffness parameters of the metacarpophalangeal joints of the index, middle, and ring fingers of both hands. The apparatus is simple and quick to use and gives reproducible results. The arthrograph is used to determine the reference limits for stiffness at the middle finger of the right hand in 128 normal subjects. ...

Revision metacarpophalangeal arthroplasty after silicone implant arthroplasty is frequently complicated by severe bone loss, osteolysis and diaphyseal perforations. Impacted, morselised allografts are frequently used to treat bone loss in revision surgery. A new method of treatment using bioreconstructive poly-L/D-lactic acid (PLDLA) joint scaffold and allograft bone packing, after complete rem...

INTRODUCTION Multiple dislocations of joints in the hand are rare. Double dislocations of the thumb joints have only been reported on four previous occasions, in all cases reported to date, the joints have dislocated dorsally. CASE REPORT We present the case of a 26-year-old male patient with simultaneous volar dislocations of the carpometacarpal and metacarpophalangeal joints of the thumb. T...

[Purpose] The purpose of this study was to investigate on the effects of the stepwise application of orthosis and kinesiology tape on a patient with thumb metacarpophalangeal joint hyperextension injury. [Subject] The patient was a 43-year-old man with severe thumb MCP pain and extremely limited thumb movement. [Methods] Stepwise application of orthosis and kinesiology taping were performed for...

Using morphological data describing the physiological curvature morphology of the corresponding articulating surfaces in each finger joint, it is shown that a) the flexion of each finger joint is described by two angles of flexion; b) in each finger joint, a "pump mechanism" for synovial fluid is present whose function is to lubricate and nourish the joint cartilage and c) finger posture has si...
