OBJECTIVE Neonatal brachial plexus palsy (NBPP) occurs due to the stretching of the nerves of the brachial plexus before, during, or after delivery. NBPP can resolve spontaneously or become persistent. To determine if nerve surgery is indicated, predicting recovery is necessary but difficult. Historical attempts explored the association of recovery with only clinical and electrodiagnostic examinations. However, no data exist regarding the neonatal and peripartum factors associated with NBPP persistence. METHODS This retrospective cohort study involved all NBPP patients at the University of Michigan between 2005 and 2015. Peripartum and neonatal factors were assessed for their association with persistent NBPP at 1 year, as defined as the presence of musculoskeletal contractures or an active range of motion that deviated from normal by > 10° (shoulder, elbow, hand, and finger ranges of motion were recorded). Standard statistical methods were used. RESULTS Of 382 children with NBPP, 85% had persistent NBPP at 1 year. A wide range of neonatal and peripartum factors was explored. We found that cephalic presentation, induction or augmentation of labor, birth weight > 9 lbs, and the presence of Horner syndrome all significantly increased the odds of persistence at 1 year, while cesarean delivery and Narakas Grade I to II injury significantly reduced the odds of persistence. CONCLUSIONS Peripartum/neonatal factors were identified that significantly altered the odds of having persistent NBPP at 1 year. Combining these peripartum/neonatal factors with previously published clinical examination findings associated with persistence should allow the development of a prediction algorithm. The implementation of this algorithm may allow the earlier recognition of those cases likely to persist and thus enable earlier intervention, which may improve surgical outcomes.

Intraoperative Localization

Abstract OBJECTIVE Exact intraoperative localization of pathologies in spinal and peripheral nerve surgery is not easily achieved. In spinal surgery, intraoperative fluoroscopy is the common method for identification of the level affected. It seldom visualizes the pathology itself and is prone to error in identifying anatomic disorders and superimposing structures. In peripheral nerve surgery, intraoperative fluoroscopy is of little value. The present technical study was conducted to evaluate the feasibility of using a preoperative computed tomography–guided needle marking system, which was previously developed for use in gynecology. The goal was to reduce intraoperative localization error and radiation exposure to patients and operating room personnel. METHODS We used a flexible hooked-wire needle marking system, which has previously been used for preoperative marking of breast lesions, to localize and tag spinal and peripheral nerve pathologies. Marking was carried out under computed tomographic control before surgery. Seven illustrative cases were chosen for this report: 6 patients with disorders of the spine and 1 patient with a peripheral nerve schwannoma. RESULTS No adverse reactions, aside from minor discomfort, were observed in this study. In all cases, the needle could be used as a reliable guide for the surgical approach and led directly to the pathology. In no case was additional intraoperative fluoroscopy needed. The level of radiation exposure to the patient as a result of computed tomography–based marking was similar to or less than that encountered in conventional intraoperative x-ray localization. Radiation exposure to the operating room personnel was eliminated by this method. CONCLUSION Preoperative marking of spinal level or peripheral nerve pathologies with a flexible hooked-wire needle marking system is feasible and appears to be safe and useful for neurosurgical spinal and peripheral procedures.

Abstract BACKGROUND Clinical and electrophysiological assessments prevail in evaluation of traumatic nerve lesions and their regeneration following nerve surgery in humans. Recently, high-resolution neurosonography (HRNS) and magnetic resonance neurography have gained significant importance in peripheral nerve imaging. The use of the grey-scale-based “fascicular ratio” (FR) was established using both modalities allowing for quantitative assessment. OBJECTIVE To find out whether FR using HRNS can assess nerve trauma and structural reorganization in correlation to postoperative clinical development. METHODS Retrospectively, 16 patients with operated traumatic peripheral nerve lesions were included. The control group consisted of 6 healthy volunteers. All imaging was performed with a 15 to 6 MHz ultrasound probe (SonoSite X-Porte; Fujifilm, Tokyo, Japan). FR was calculated using Fiji (兠) on 8-bit-images (“MaxEntropy” using “Auto-Threshold” plug-in). RESULTS Thirteen of 16 patients required autologous nerve grafting and 3 of 16 extra-intraneural neurolysis. There was no statistical difference between the FR of nonaffected patients’ nerve portion with 43.48% and controls with FR 48.12%. The neuromatous nerve portion in grafted patients differed significantly with 85.05%. Postoperatively, FR values returned to normal with a mean of 39.33%. In the neurolyzed patients, FR in the affected portion was 78.54%. After neurolysis, FR returned to healthy values (50.79%). Ten of 16 patients showed clinical reinnervation. CONCLUSION To our best knowledge, this is the first description of FR using HRNS for quantitative assessment of nerve damage and postoperative structural reorganization. Our results show a significant difference in healthy vs lesioned nerves and a change in recovering nerve portions towards a more “physiological” ratio. Further evaluation in larger patient groups is required.
