After injury of the brachial plexus, sensory disturbance in the affected limb varies according to the extent of root involvement. The goal of this study was to match sensory assessments and pain complaints with findings on CT myelo scans and surgical observations. One hundred fifty patients with supraclavicular stretch injury of the brachial plexus were operated upon within an average of 5.4 months of trauma. ⋯ Hand sensation was largely preserved in patients with partial injuries of the brachial plexus, particularly on the radial side. Even when T1 was the only preserved root, hand sensation was mostly spared. This indicates that overlapping of the dermatomal zones seems much more widespread than previously reported.
