Yukata K, Doi K, Okabayashi T, et al. - This study was undertaken to evaluate the effect of shrug radiographs for the diagnosis of long thoracic nerve palsy in traumatic brachial plexus injury. Researchers performed a retrospective review including a total of 56 patients with traumatic brachial plexus injury (BPI) who had been receiving treatment at a single institution for over 8 years. Individuals were categorized into 2 groups: a long thoracic nerve (LTN) palsy group (n = 30) and a no palsy control group (n = 26). It was shown that after traumatic BPI, dynamic shrug radiographs provide a useful objective diagnosis of LTN palsy.
