Four-dimensional computed tomography (4DCT) allows for the assessment of the wrist contact mechanics and kinematics during motion. The purpose of this study was to employ 4DCT to measure the differences in joint surface area (JSA) (3D joint space) at the radioscaphoid, radiolunate, and distal radioulnar joints between a cohort of participants with a distal radius fracture (DRF) and an age-matched cohort of healthy participants. Our results indicated that following a DRF, there was a 20% decrease in JSA at the DRUJ when compared to the healthy (control) cohort. This study demonstrated the use of a non-invasive tool to examine wrist contact mechanics.
四维计算机断层扫描（4DCT）能够评估运动过程中腕关节的接触力学和运动学。本研究的目的是利用4DCT测量桡骨远端骨折（DRF）患者队列与年龄匹配的健康参与者队列之间，在桡舟关节、桡月关节和桡尺远侧关节处的关节表面积（JSA）（三维关节间隙）差异。我们的结果表明，与健康（对照）队列相比，DRF后桡尺远侧关节的JSA下降了20%。本研究证明了使用非侵入性工具来检查腕关节接触力学。
