The reproducibility of the radiographic measurement of 30 pairs of tibiae being treated for bowing was evaluated. Two methods of measurement were used. The first was the metaphyseal-diaphyseal angle of Levine and Drennan; the second, a metaphyseal-metaphyseal angle based on Cobb's angle for measuring scoliosis. Statistical analysis comparing the two methods showed no significant differences except for an increase in the angle in more severe cases measured by the metaphyseal-metaphyseal method, indicating distal tibial as well as proximal involvement. Computer digitization correlated extremely well with manual measurements. The metaphyseal-diaphyseal measurement is quite reproducible, and may allow early diagnosis and treatment of tibia vara.
对30对正在接受弓形腿治疗的胫骨进行X线测量的可重复性进行了评估。采用了两种测量方法。第一种是Levine和Drennan提出的干骺端-骨干角；第二种是基于测量脊柱侧弯的Cobb角的干骺端-干骺端角。比较这两种方法的统计分析表明，除了用干骺端-干骺端方法测量的更严重病例的角度有所增加外，没有显著差异，这表明胫骨远端以及近端均受累。计算机数字化与手工测量的相关性非常好。干骺端-骨干测量具有相当高的可重复性，并且可能有助于胫骨内翻的早期诊断和治疗。
