Traumatic Posterior Fossa Subdural Hemorrhage: A Multicenter, Retrospective Cohort Study.
Traumatic posterior fossa subdural hemorrhage (SDH) is a rare subtype of subdural hemorrhage in head injuries. Existing data on its pathophysiology and outcome are currently limited; therefore, the condition is not yet fully understood. The present study aimed to determine the incidence, outcome, and prognostic factors for traumatic posterior fossa SDH. ⋯ Traumatic posterior fossa SDH was extremely rare in our data set. Mortality correlated with the size of the SDH, GCS score on admission, and the presence of a skull fracture.

Clinical Usefulness of Waiting after Stent Deployment in Mechanical Thrombectomy: Effect of the Clot Integration.
Pulling a retriever stent after several minutes of waiting time is a popular technique in mechanical thrombectomy with a stent retriever, but little data exist on the actual effects of waiting after stent deployment. ⋯ Waiting after stent deployment can lead to a more successful recanalization with a smaller number of stent passages and less distal emboli. More randomized controlled trials are needed to support these findings.

Sacroiliac (SI) joint fusion is considered for the treatment of degenerative sacroiliitis. The procedure has increased in popularity for patients who have exhausted less invasive treatment options since the development of percutaneous SI joint fusion systems. One possible complication of the procedure is a sacral radiculopathy that can result from compression of the S1 nerve by the SI joint fusion implant. Others have described revising the implant by removing it and replacing it with a shorter implant. ⋯ This technical note is for others to consider as a possible minimally invasive solution for the treatment of lumbar radiculopathy after a minimally invasive SI joint fusion procedure.

Although many studies have investigated functional localization by electrical stimulation, the threshold to identify each area remains controversial. The present study aimed to elucidate the threshold of a cortical stimulation for functional mapping. ⋯ Positive and sensory effects are induced by lower intensities than negative and motor responses, respectively. The present results provide not only a practical guide for functional mapping, but also a hierarchal concept of processing in the brain.

The incidental dural tear is a common complication in lumbar spine surgery. It has been reported that the incidence of dural tears is much greater in endoscopic procedures. Primary closure via suturing remains challenging in endoscopic procedures. The objective of this study was to conduct a literature review on the surgical technique for dural closure and repair in endoscopic spine surgery. ⋯ An autologous muscle or fat graft in combination with fibrin glue or a fibrin-sealed collagen sponge seems to be a good and safe method for the management of dural tear in lumbar endoscopic spine surgery.
