UNASSIGNED: Eighty-two intact upper extremity computed tomography angiography scans were examined and reconstructed into 3D models. We characterized ulnar bowing and DRUJ metrics using computer-aided design software. Measures of central tendency and Pearson correlation coefficients were calculated for comparative analysis.
UNASSIGNED: The study yielded an average ulnar length of 272.3 mm. We identified the proximal ulnar bow at 36.7% of the bone\'s total length, possessing a depth of 10.3 mm, a proximal angle of 6.6°, and a distal angle of 3.9°. The distal ulnar bow appeared at 75.3% of the bone\'s length, characterized by a depth of 4.2 mm, a proximal angle of 2°, and a distal angle of 4.3°. In the coronal plane, the proximal angle of the proximal ulnar bow correlated positively with UV (r = 0.39, P < .001), whereas the distal angle of the distal ulnar bow correlated negatively (r = -0.48, P < .001). We also found significant correlations between the depths of both proximal and distal bows with UV (r = 0.38, P < .001; r = -0.34, P < .001, respectively). Moreover, UV within the DRUJ strongly correlated with the sigmoid notch angle (r = -0.77, P = .01). In contrast, the sagittal plane metrics did not show meaningful correlations with UV.
UNASSIGNED: Sagittal alignment and translation at the DRUJ articulation are directly related to ulna bowing at the distal ulna. A nuanced understanding of these 3D relationships can enhance preoperative planning when correcting ulnar-side pathology.
UNASSIGNED: Therapeutic IV.
■检查了82次完整的上肢计算机断层扫描血管造影扫描并重建为3D模型。我们使用计算机辅助设计软件对尺骨弯曲和DRUJ指标进行了表征。计算集中趋势和皮尔逊相关系数的度量进行比较分析。
■该研究得出272.3mm的平均尺骨长度。我们确定近端尺骨弓占骨骼总长度的36.7%,深度为10.3毫米,6.6°的近端角度,和3.9°的远端角度。尺骨远端弓出现在骨长度的75.3%处,以4.2毫米的深度为特征,2°的近端角度,和4.3°的远端角度。在日冕平面上,尺弓近端角度与紫外线呈正相关(r=0.39,P<.001),而远端尺骨弓的远角呈负相关(r=-0.48,P<.001)。我们还发现近端和远端弓的深度与紫外线之间存在显着相关性(分别为r=0.38,P<.001;r=-0.34,P<.001)。此外,DRUJ内的紫外线与S形切口角密切相关(r=-0.77,P=0.01)。相比之下,矢状平面指标与紫外线没有显示有意义的相关性.
■DRUJ关节处的矢状对齐和平移与尺骨远端的尺骨弯曲直接相关。对这些3D关系的细微了解可以在纠正尺侧病理时增强术前计划。
