The Spaghetti Sign: Nerve Root Redundancy in Lumbar Spinal Stenosis.

Objective: Redundant nerve roots (RNRs) seen in conjunction with lumbar spinal stenosis (LSS) are well-described radiographic findings. Several studies suggest their presence may be a negative prognostic indicator of postoperative outcome. Our hypothesis was that severe RNR (informally known as the spaghetti sign [SS]) can serve as a reliable marker of LSS that would benefit from surgical decompression.

Social Media and Academic Impact: Do Early Tweets Correlate with Future Citations?

Objective: This study aims to determine whether social media platforms (SMPs) can influence article impact as measured by citations.

Methods: This is a cross-sectional study that analyzed articles published in the top ten otolaryngology journals by the Eigenfactor score in January 2015. Total accumulated twitter mentions and citations were recorded in 2021.
