The objective of this study was to characterize the biomechanical implications of spinous process compression, via in situ shortening of a next-generation interspinous process fixation (ISPF) device, in the context of segmental fusion. ⋯ In situ shortening of an adjustable ISPF device may support increased segmental stabilization compared with static ISPF.

Sonolucent cranioplasty implants were recently introduced into clinical practice and tested for use with transcranioplasty ultrasound (TCUS). In situations where dural substitutes (DSs) are needed during closure, such as in extracranial-intracranial bypass, it is unclear if the DS influences the imaging quality of TCUS. The aim of this study was to assess the influence of DSs on imaging quality during TCUS assessment with sonolucent cranioplasty. ⋯ DSs interfere differentially with imaging quality during TCUS assessment. However, these results are based on a benchtop model and need to be further assessed in the clinical setting.

Anterior spinal artery steal syndrome, radiculomedullary artery aneurysms, and pulmonary arteriovenous malformations with a systemic origin are each, considered individually, exceptional conditions. ⋯ Eventually, the lesion was treated with the exclusion of the left C8 spinal segmental branch and embolization of the arteriovenous malformation.

Cervical Spine and Craniocervical Junction Reconstruction with a Vascularized Fibula Free Flap: A Case Report.
Long-term stabilization of the cervical spine after extensive multilevel tumor resection is difficult to achieve. The current standard approach of instrumentation combined with allograft or nonvascularized autograft is limited in settings of increased risk of nonunion or delayed union (i.e., prior radiation therapy or poorly vascularized wound beds). ⋯ Vascularized bone grafting is a viable alternative to achieve lasting stability because of hastened fusion time, limited reliance on osseous remodeling, and incorporation into the axial skeleton with strut strength.

Recurrent hydrocephalus may occur as a complication of neurosarcoidosis with chronic inflammation. We present a case that required a combination of multistage endoscopic diversion of the cerebrospinal fluid pathway and shunt surgery. ⋯ Endoscopic diversion of the cerebrospinal fluid pathway should be actively considered for treating hydrocephalus without a shunt and performing biopsy simultaneously. Even if a subsequent shunt is needed, complex hydrocephalus can be avoided with a combination of endoscopic techniques.
