Abstract:

BACKGROUND: Different exercises exert varying mechanical load on body, which have diversity effects on bone mineral density.
OBJECTIVE: To study the structure differences of the forced carpal bones in the two sports wushu gongli and tennis by use of a spiral CT.
METHODS: Eight male wushu athletes and 7 tennis athletes were selected. The carpal bones of the wushu and tennis athletes were scanned by the spiral CT. and the two-dimensional images were filtered, screening reduced, enlarged, enhanced, and splited, then the gray and area of pisiform and triquetrum were measured.
RESULTS AND CONCLUSION: The gray scale of coronal, horizontal and sagittal sections of the pisiform in wushu athletes were greater than that of tennis athletes (P < 0.05), with smaller areas (P < 0.05). There was no significant gray scale difference of three sections of the triquetrum between two groups, while the area in wushu athletes was less than that in tennis athletes (P < 0.01). The experiment showed that there were some structure differences of the carpal bones between gongli and tennis sports. The bone mineral density of some parts of the carpal in gongli was greater than that in tennis, but the area was reduced in gongli.
