To evaluate the efficacy and safety of the novel Femoral-Long Sheath-Reshape-Anchoring-Stenting (FLRAS) technique (developed by Dr. Hongbo Zheng) for venous sinus stenting in patients with idiopathic intracranial hypertension. ⋯ Use of FLRAS technique for venous sinus stenting in patients with idiopathic intracranial hypertension appeared to yield favorable outcomes relative to use of the traditional stenting technique. A large, multicenter, randomized study is warranted to confirm these findings.

Osteonecrosis of bone flaps after cranioplasty with autologeous cryo-conserved bone flaps is a common phenomenon. The exact reason for it remains unknown. ⋯ We discuss similarities with aseptic implant loosening and present recent evidence that low-grade infections might be the underlying reason in several cases. We conclude that low-grade infections play an underestimated role in bone flap necrosis after cranioplasty as well and encourage routine microbiological sampling (extended culture and PCR) to rule out infection in all similar cases and suggest a routine antibiotic therapy until final microbiological results.

Transforaminal epidural steroid injections (TFESIs) have been increasingly used in the treatment of lumbar radicular pain resistant to conservative modalities. Although different steroids can be used at different doses, the minimally effective steroid dose should be used to reduce side effects. The present retrospective study examined and compared the efficacy of 40 mg and 80 mg of methylprednisolone in TFESIs. ⋯ TFESIs with 40 mg and 80 mg are effective for the treatment of pain that results from lumbar disc herniation. They also positively affect patients' disability and quality of life. However, neither steroid dose was more efficient than the other dose. Therefore, we believe the smaller dose should be preferred to reduce the potential side effects of steroids.

Detrusor sphincter dyssynergia, involuntary detrusor contractions (IDCs), and poor bladder compliance are common urodynamic findings in cervical spondylotic myelopathy (CSM). There is little information regarding the role of a urodynamic study after decompression surgery for CSM. ⋯ Neurogenic bladder could be partially controlled in patients with CSM after surgical decompression. The neurogenic component in the urodynamic study findings varied. Depending on the findings, further appropriate urologic treatments after neurologic decompression surgery should be considered.

To explore the appropriate range of C0-C2 correction angles by analyzing cervical sagittal alignment parameters and evaluating clinical outcomes. ⋯ Atlantoaxial dislocation patients with different C0-C2 postoperative angles had different cervical sagittal alignments and clinical outcomes. In our study, the patients within the C0-C2 10°-20° subgroup exhibited superior clinical outcomes and cervical sagittal alignment.
