Inroduction: Spinal Epidural Lipomatosis (SEL) is believed to be a rare disorder. The incidence and prevalence of clinically symptomatic SEL in patients with spinal stenosis has never been reported in the literature. Our study aims to determine the prevalence, incidence, and associated risk factors of SEL in patients with the diagnosis of spinal stenosis.
Methods: This is a retrospective study. We reviewed the charts of 831 patients with the diagnosis of spinal stenosis over a 30 month period. All patients had spinal MRIs. Grading of SEL was performed using the Borré method.
Results: 52 patients (21 female and 31 male) had symptomatic moderate and severe SEL. We found a prevalence of 6.26% and an annual incidence of 2.5%. SEL was most commonly seen at L5-S1 level. 27% had received corticosteroids. All SEL patients were overweight and 79% were obese.
Conclusions: SEL is not uncommon in patients with spinal stenosis. SEL should be considered as a possible diagnosis in those with symptoms of spinal stenosis especially in those with associated risk factors.

Objectives: To determine whether deep learning-based reconstructions of zero-echo-time (ZTE-DL) sequences enhance image quality and bone visualization in cervical spine MRI compared to traditional zero-echo-time (ZTE) techniques, and to assess the added value of ZTE-DL sequences alongside standard cervical spine MRI for comprehensive pathology evaluation.
Methods: In this retrospective study, 52 patients underwent cervical spine MRI using ZTE, ZTE-DL, and T2-weighted 3D sequences on a 1.5-Tesla scanner.
Preoperative Evaluation of Oswestry Disability Index in Lumbar Spinal Stenosis: New Evidence of Time Independence of Variation Up to 1 Year.

Natural Resources Institute Finland, Natural Resources, Joensuu, Finland.
Background: The Oswestry Disability Index (ODI) is a well-validated and widely used patient-reported outcome instrument to evaluate lumbar spinal stenosis (LSS) patients' treatment outcomes. The objective of the present study was to determine long the average interval between 2 preoperative measurements can be before a clinically significant difference of 10 points or more might appear.
Methods: This was a retrospective observational study utilizing prospectively collected data from a single university hospital database, which was compatible with the national registry.
A Rare Case of Bilateral Foot Drop Following Cervical Decompression in Tandem Spinal Stenosis.

December 2024
Orthopaedic Surgery, Ng Teng Fong General Hospital, Singapore, SGP.
This case report describes a 70-year-old male presenting with limb weakness, urinary retention and tandem cervical and lumbar spinal stenosis with complicating white cord syndrome, a rare reperfusion injury post decompression surgery. Initially admitted following an unwitnessed fall, the patient's neurological examination indicated that progressive weakness of the limbs and sensory loss etiology is cervical and lumbar spondylosis with severe spinal canal stenosis, confirmed by imaging. Due to rapid deterioration, he underwent C5 corpectomy, cervical decompression and fusion.
