title: Strain development in carpal scaphoid for various wrist positions: a cadaveric study using strain gauges.
abstract: In order to investigate the ideal position in which the wrist should be immobilized during scaphoid fracture, treatment the strains which are developed in the carpal scaphoid for various wrist positions has been recorded in cadaveric wrists, using strain gauges. The data obtained shows that during radial deviation with neutral or slight palmar flexion of the wrist the waist of the scaphoid tends to compress because of the development of strong compressive strains, while the strain development parallel to the fracture site that tends to shift the scaphoid waist is minimum. This position seems to be the best for stable scaphoid fracture immobilization.
