Risk Factors Affecting Cage Retropulsion into the Spinal Canal Following Posterior Lumbar Interbody Fusion: Association with Diffuse Idiopathic Skeletal Hyperostosis.
Conclusions: DISH and multilevel PLIF were significant risk factors affecting cage retropulsion. Revision surgery for cage retropulsion revealed PS loosening, suggesting that implant replacement was necessary to prevent repeat cage retropulsion after revision.

Current Concepts in the Management of Osteoporotic Vertebral Fractures: A Narrative Review.
Authors: Jang HD, Kim EH, Lee JC, Choi SW, Kim K, Shin BJ Abstract Vertebral fractures are the most common type of osteoporotic fracture and can increase morbidity and mortality. To date, the guidelines for managing osteoporotic vertebral fractures (OVFs) are limited in quantity and quality, and there is no gold standard treatment for these fractures. Conservative treatment is considered the primary treatment option for OVFs and includes pain relief through shortterm bed rest, analgesics, antiosteoporotic drugs, exercise, and braces. Studies on vertebral augmentation (VA) including vertebroplasty and kyphoplasty ha...

Cervical Radiculopathy Focus on Characteristics and Differential Diagnosis.
Authors: Kang KC, Lee HS, Lee JH Abstract Cervical radiculopathy is characterized by neurological dysfunction caused by compression and inflammation of the spinal nerves or nerve roots of the cervical spine. It mainly presents with neck and arm pain, sensory loss, motor dysfunction, and reflex changes according to the dermatomal distribution. The most common causes of cervical radiculopathy are cervical disc herniation and cervical spondylosis. It is important to find the exact symptomatic segment and distinguish between conditions that may mimic certain cervical radicular compression syndromes through meticulous p...

Conjoint Nerve Root an Intraoperative Challenge in Minimally Invasive Tubular Discectomy.
Authors: Sharma A, Singh V, Agrawal R, Mangale N, Deepak P, Savla J, Jaiswal A Abstract Conjoint nerve root (CNR) is an embryological nerve root anomaly that mainly involves the lumbosacral region. The presence of CNR during tubular discectomy raises the chances of failure in spinal surgery and the risk of neural injuries. Tubular discectomy can be challenging in the presence of CNR owing to limited visualization. Here, we present a technical note on two cases of L5-S1 disc prolapse in the presence of conjoint S1 nerve root that was operated via a minimally invasive tubular approach.
