Patients with dialysis are at high risk of reoperation after lumbar spinal fusion surgery. However, the risk of reoperation after short-segment (≤2 fusion levels) lumbar spinal fusion surgery in this patient group has not been completely investigated. This study aimed to compare the risk of reoperation after short-segment lumbar spinal fusion surgery between patients with dialysis and matched controls without dialysis.

Article Synopsis
- The report discusses a case of an eight-year-old boy who suffered a Jefferson fracture with a related unstable avulsion fracture and damage to the transverse atlantal ligament.
- The patient was treated conservatively with a halo vest and a SOMI brace, leading to a full recovery.
- Follow-up imaging showed successful healing of the injury and stability at the C1/2 spinal level, contributing valuable insights into managing rare pediatric neck injuries without surgery.
Quantitative Threshold of Intraoperative Radiological Parameters for Suspecting Oblique Lumbar Interbody Fusion Cage Malposition Triggering Contralateral Radiculopathy.

Background: This study aimed to clarify the quantitative threshold of intraoperative radiological parameters for suspecting posterior malposition of the oblique lumbar interbody fusion (OLIF) cage triggering contralateral radiculopathy.
Methods: We measured the sagittal center and axial rotation angle (ARA) of the cage using postoperative computed tomography (CT) in 130 patients (215 cages) who underwent OLIF. The location of the cage tip was determined from axial magnetic resonance imaging in selected cases based on CT simulations to assess whether the cage was in contact with the contralateral exiting nerve or whether the surgical instruments could contact the nerve during intradiscal maneuvers.
Surgical outcomes of intraoperative O-arm versus C-arm fluoroscopy in occipitocervical fixation: a retrospective analysis.

Purpose: This study aims to compare the effect of using O-arm and C-arm fluoroscopy on the surgical outcomes of occipitocervical fixation.
Methods: The study included patients who underwent occipitocervical fixation using O-arm or C-arm between 2005 and 2021. Of 56 patients, 34 underwent O-arm-assisted surgery (O-group) and 22 underwent C-arm-assisted surgery (C-group).
