Degenerative spondylolisthesis refers to a forward displacement of a vertebra relative to the underlying vertebra. Patients with radicular pain and/or neurogenic claudication are considered suitable candidates for surgical intervention. The aim of this study was to present clinical results of dynamic stabilization applied after pediculectomy and neural foramen enlargement in patients with degenerative spondylolisthesis and normal spinal sagittal balance. ⋯ In patients without any pathology in the sagittal balance, the optimal physiological treatment modality can be created by applying posterior dynamic stabilization together with pediculectomy to support the posterior tension band.

Neurovascular compression syndromes (NVCSs) are a group of neurological disorders characterized by compression of a cranial nerve and include trigeminal neuralgia (TN), hemifacial spasm, geniculate neuralgia, glossopharyngeal neuralgia, vestibular paroxysmia, and trochlear palsy. The European Academy of Neurology recommends constructive interference in steady-state/fast imaging employing steady-state (CISS/FIESTA) magnetic resonance imaging (MRI) in the evaluation of medically intractable TN, but similar recommendations do not exist for the remaining NVCSs. ⋯ Preoperative CISS/FIESTA MRI correlated with greater rates of surgical success in cases of medically intractable TN; however, definitive conclusions could not be made regarding the remaining NVCSs. We support the recommendation that this imaging modality be included as part of the standard of practice for the evaluation and management of TN and encourage future studies to further elucidate this relationship for the less common NVCSs using a larger cohort.

Nerve root injury and dural tears are important complications in endoscopic spine techniques. Whether Kambin's triangle is safe or not is unknown for percutaneous endoscopic transforaminal oblique fixation from the posterior corner (PETOFPC) in lumbar spine. This study aimed to verify neural safety of PETOFPC and to define and evaluate the ideal operating target and actual safe working area in Kambin's triangle for PETOFPC. ⋯ We calculated the ideal operating target and actual safe area and further proved that Kambin's triangle is safe enough for PETOFPC. PETOFPC is a promising technology and may have great clinical significance.

To provide an analysis of patients with spontaneous skull base meningoencephaloceles (MECs) to determine whether definitive surgical treatment requires management of elevated intracranial pressure (ICP). ⋯ Spontaneous MECs are often associated with CSF leak. ICP assessment should be a standard of care to ensure successful operative repair of MECs. Insertion of a CSF diversion device must be considered where direct or indirect signs of intracranial hypertension are present.

The accuracy of pedicle screws placed with instrument tracking and robotic navigation are individually comparable or superior to placement using standard fluoroscopy, however head-to-head comparisons between these adjuncts in a similar surgical population have yet to be performed. ⋯ In a similar patient population, there is a similarly high degree of instrumentation accuracy between fluoroscopy-based instrument tracking and robotic navigation. There is a rare chance for screw breach with either surgical adjunct.
