Hounsfield Unit Utilization in Cervical Spine for Bone Quality Assessment: A Scoping Review.
J Clin Med
January 2025
Department of Neurosurgery, Montefiore Medical Center, Bronx, NY 10461, USA.
Bone mineral density (BMD) is an essential indicator of bone strength and plays a crucial role in the clinical management of various spinal pathologies. Hounsfield units (HUs) calculated from computed tomography (CT) scans are a well-established, effective, and non-invasive method to determine bone density in the lumbar spine when juxtaposed to dual-energy X-ray absorptiometry (DEXA) scans, the gold standard for assessing trabecular bone density. Only recently have studies begun to investigate and establish HUs as a reliable and valid alternative for bone quality assessment in the cervical spine as well.

The scope of existing annular closure device (ACD) studies examining long-term follow-up data is limited. There is a paucity of studies that report and analyze recent outcomes data following ACD use. We sought to summarize the available long-term follow-up data on postoperative outcomes of the Barricaid (Intrinsic Therapeutics) ACD.

Intradural Disk Herniation at the Conus Medullaris: A Case Report With Emphasis on Patient Positioning and Neuromonitoring.

October 2024
Department of Spine Surgery, Hospital for Special Surgery, New York, New York.
Case: A 73-year old man who underwent previous L2-S1 decompression presenting with new right radicular leg pain. Imaging suggests a large central disk herniation at L1-2 with possible intrathecal extension requiring surgical decompression. When positioned prone on a Jackson frame, neuromonitoring motor signals became diminished, and thus, the case was aborted.

Aim: Minimally-invasive spinal surgery is increasingly being adopted worldwide. In this study, we evaluated the postoperative magnetic resonance imaging (MRI) findings and clinical outcomes of patients who underwent full endoscopic lumbar disk surgery.
Methods: Preoperative and postoperative 3rd and 6th month MRI features, visual analog scale (VAS) score, Oswestry Disability Index (ODI), and clinical features of patients who underwent percutaneous endoscopic lumbar discectomy between August 2009 and January 2012 were retrospectively analyzed.
