BACKGROUND: Ultrasound has been utilized in the evaluation of compressive and traumatic peripheral nerve pathology. OBJECTIVE: To determine whether US can provide comprehensive evaluation of the post-ganglionic brachial plexus in the setting of neonatal @entity5300 and whether this information can be used to guide preoperative nerve reconstruction strategies. MATERIALS AND METHODS: In this retrospective cohort study, preoperative brachial plexus ultrasonography was performed in 52 @entity1 with neonatal @entity5300 who were being considered for surgery. The 33 @entity1 who had surgery compose the @entity1 cohort. The presence and location of post-ganglionic @entity2950 were evaluated by US and compared to the surgical findings. US evaluation of shoulder @entity2057 was conducted as an indirect way to assess the integrity of nerves. Finally, we correlated glenohumeral joint laxity to surgical and clinical management. RESULTS: Ultrasound correctly identified 21 of 25 cases of upper trunk and middle trunk @entity2950 involvement (84% sensitivity for each). It was 68% sensitive and 40% specific in detection of lower trunk involvement. US identified shoulder @entity2057 in 11 of 21 @entity1 evaluated; 8 of these 11 went on to nerve transfer procedures based upon the imaging findings. US identified 3 cases of shoulder joint laxity of the 13 @entity1 evaluated. @entity5953 cases were referred for orthopedic evaluation, with 1 @entity1 undergoing shoulder surgery and another requiring casting. CONCLUSION: Ultrasound can provide useful preoperative evaluation of the post-ganglionic brachial plexus in @entity1 with neonatal @entity5300 .
