The chiasma antebrachii was identified in the distal third of the forearm in 88 patients (98.9%), while one intersection was located more proximally in the middle part. The chiasma had a median length of 28 mm (interquartile range: 24–35 mm). Its median distances to the distal radioulnar and elbow joint were 16 mm (8–25 mm) and 215 mm (187–227 mm), respectively. The best MRI sequence for its depiction was found to be a T1-weighted post-contrast sequence (71 cases, 79.8%), followed by T2- or proton density-weighted sequences. In the sample of cadaveric specimens, the chiasma was identifiable in every distal forearm.
