To evaluate the effect of the basilar invagination (BI) type B on cervical spine. ⋯ The deformation of skull base in the BI of type B caused, on average, a hyperlordosis of almost 30° in the C2-C6 segment. This change was approximately 17° in the C2-C4, with the clivus hypoplasia being a risk factor for cervical hyperlordosis.

To evaluate the short-term surgical outcomes and the reimbursement patterns, after treatment of type 2 odontoid fractures using the anterior or posterior approach. ⋯ In this matched analysis, the anterior approach for type 2 odontoid fractures was superior to the posterior approach. The anterior approach was associated with significantly shorter operation times, hospital stays, fewer transfusions, nonroutine discharges, and higher reimbursements.

To objectively correlate distortions of optic apparatus morphology in patients with pituitary adenomas undergoing trans-sphenoidal surgery. ⋯ Anatomic realignment of the optic apparatus 3 months following trans-sphenoidal surgery predicts VF scores, but not VA or TV scores at 1-year follow-up. Patients with preoperative ONKA values of more than 139.3° have a 76% chance of achieving normal TV scores 1 year after surgery. Postoperative chiasm sag appears to be clinically irrelevant at short-term follow-up.

Supportive radiologic signs may be needed to diagnose spondylolysis (SL) via lumbar magnetic resonance imaging (MRI). In SL, the slight displacement of the corpus forward and lamina posteriorly can cause the interposition of posterior epidural fat (EFI), which is normally segmental. This study aimed to determine the diagnostic value of EFI, an indirect sign of SL, on lumbar mid-sagittal T1-weighted MRI. ⋯ EFI is an indirect radiological finding with high reliability in diagnosing SL with mid-sagittal T1-weighted images in lumbar MRI.
