A CT Imaging Study On The Effect Of Different Stress Stimulation On The Carpal Structure

Mechanical environment can influence the bone morphology which has become the basic principles of bone physiology. Movement was the main form of external stress, mode of exercise,sort of exercise,exercise time and so will have an impact on bone mineral density (BMD). The purpose of this paper is to research the differences of the bone mineral density and structure of the carpal bones between wushu gongli and non-wushu athletes by medical image and image processing. The area and image intensity of capitate and hamate were measured used by spiral CT and image processing, then analysed statistically. The athletes of wushu gongli were experimental group and non-wushu control.The results: (1) self-comparison of the right and laft hand of experimental and control groups:the gray values of right hand of two groups were larger than laft hand (P<0.01); the area of two carpal of experimental group were almost equal; the area of capitatum of control group was almost equal,in which the gray values of hamate of right hand was larger than laft (P<0.01). (2) experimental group compare with control: the gray values of right hand capitatum, two carpal of laft hand in experimental group was larger than that in the control (P<0.01); the gray values of hamate in two groups were almost equal;the area of capitatum in experimental group was less than that in the control (P<0.05); the gray values of hamate in two groups were almost equal; the area of hamate in experimental group were less than that in the control (P<0.05).The resule of this study showed that compared with non-wushu sports, wushu gongli sports might increase the BMD and decrease the volume of the carpal bones (capitate and hamate).
