Objective: The aim of this study is searching morphometrical effects of weightlifting sports on metacarpal bones.
Materials and Methods: This study includes 9 weightlifters male adult and 9 sedentaries male adult who have not been involved in sport activities. Two dimensional (2D) images of weightlifters’ and the sedentaries’ right-left hand finger bones’ were obtained by using multidetector computed tomography (MDCT), 2D MDCT images were converted to 3-dimensional by using software Mimics 13.1.
Indications/Results: Although volume of many metacarpals bone of weightlifters’ has higher volume value than sedentaries, meaningful length and volume difference of metacarpals has not been found. Comparing to right and left hand metacarpal bones’ volume of weightlifters any difference was not determined. Comparing to sedentaries’ right and left hand metacarpal bone volume with weightlifters; volume values of right hands’ first, forth and fifth bones (I, IV and V) are higher than left hands’. Comparing to average percentage values of length and volume of left hand metacarpal bones; meaningful difference between sedentaries and weightlifters groups were not retained.
Conclusion: No statistical difference were determined between weightlifters and sedentaries differences in regard to both volume and length of metacarpals. However comparisons carried out within the group; volume difference between left and right hand metacarpals of sedentaries raised from dominant usage of right hand in daily life, it is thought that working with high weight may little decreased volume difference between left and right hand metacarpals of weightlifters. In addition comparing to volume and length average ratios (%) of metacarpals taken from sedentaries and weightlifters, not determining difference between sedentaries and weightlifters can be interpreted as deformation not happened in metacarpal bones of weightlifters. The technique used in this study can be used in determination structure and deformation of bone, muscle, cartilage of disabled sportsmen.
