The distal metatarsal angle (DMAA) is a measurement of the relationship between the longitudinal axis of the first metatarsal and the articular surface of the metatarsal head. We measured the DMAA on radiographs with and without markers on the articular edges and compared them with measurements of the anatomic specimens. Based on the studies, the significance of the radiographic measurements to the actual DMAA and the normal distribution of the measurement were determined.
远端跖骨角（DMAA）是第一跖骨纵轴与跖骨头关节面之间关系的一种测量方法。我们在关节边缘有标记和无标记的X线片上测量了DMAA，并将其与解剖标本的测量结果进行比较。基于这些研究，确定了X线测量对实际DMAA的意义以及测量值的正态分布情况。
