Analysis of the sagittal motion posture of the acromioclavicular joint using image registration and axial angle representation
International Journal of General Medicine May 28, 2021
Su P, Zhou JL, Yun C, et al. - This study was undertaken to assess the range of motion of the acromioclavicular joint through 3D reconstruction and image registration. Researchers recruited a total of 13 healthy volunteers in the study. They used computerized tomography (CT) to evaluate the acromioclavicular joint in four different motion poses. This study’s findings demonstrate that combining 3D reconstruction and image registration is a direct and accurate method of assessing the motion of the acromioclavicular joint. The data showed that the rotational motions of the acromioclavicular joint are bilaterally symmetrical and can be applied as a reference for comparative study. The findings suggested that during rotation, the maximum range of motion of the acromioclavicular joint was found in the resting horizontal position. It has been considered that the clinical examination and post-treatment evaluation of the acromioclavicular joint’s rotation function can thus be targeted in this range.
