High-grade L5-S1 spondylolisthesis is challenging to treat, and there is no standard recommended operative technique. The authors performed a systematic review of the literature evaluating the efficacy and safety of modern transsacral instrumentation techniques for high-grade L5-S1 spondylolisthesis. ⋯ Operative techniques for managing high-grade L5-S1 spondylolisthesis are evolving. In our systematic review, modern transsacral instrumentation resulted in good clinical outcome and fusion rates, and acceptable complication rates. Risks and benefits should be individualized for each patient. Transsacral instrumentation is a viable and effective treatment option for this pathology.

Review Case Reports
An Acute Cervical Subdural Hematoma as the Complication of Acupuncture; Case Report and Literature Review.
Several injuries in the cervical region as complications of acupuncture have been previously reported in the literature, including cord and medulla oblongata injuries, subdural empyema, and cervical hematoma. Spinal cord subdural hematoma is a rare condition mainly associated with coagulopathy, trauma, and iatrogenic procedures. We herein report an acute cervical subdural hematoma after cervical acupuncture for neck and shoulder pain. ⋯ Although rare, cervical spinal cord hematomas are disastrous complications of cervical acupuncture. These procedures should be performed under direct observation of trained physicians with appropriate knowledge of cervical anatomy to avoid these complications.

Review Case Reports
Non-calcified, hypertrophic ligamentum flavum causing severe cervical stenosis and myelopathy - A case report and review of literature.
Calcified hypertrophic ligamentum flavum is a known entity that causes myeloradiculopathy of the cervical, thoracic, and lumbar spine and is seen more commonly in Asian populations. Noncalcified hypertrophic changes are less common and may mimic other epidural space-occupying lesions. ⋯ To our knowledge, noncalcified hypertrophic ligamentum flavum causing progressive cervical myelopathy has never been reported in the English literature. This entity should be considered in cases with epidural masses causing progressive myelopathy.

Multicenter Study
Incidence and characteristics of remote intracerebral hemorrhage after endovascular treatment of unruptured intracranial aneurysms.
The purpose of this study was to investigate the incidence and characteristics of remote intracerebral hemorrhage (ICH) after endovascular treatment (EVT) of unruptured intracranial aneurysms (UIAs). ⋯ The incidence of remote ICH after EVT of UIAs was 0.46%. This event occurred mostly in patients with stents, hypertension, and UIAs on the ICA. It presented mostly as an ipsilateral lobar-type hemorrhage within 1 week after the procedure. This complication should not be neglected because of its poor clinical outcomes.

A variety of biomaterials have been developed for cranial reconstruction after craniectomy, including polyethylene titanium mesh and calcium phosphate cement. This study sought to compare complication rates of calcium phosphate cement and titanium mesh cranioplasty in patients undergoing retromastoid craniectomy. ⋯ Calcium phosphate cement cranioplasty offers an alternative to titanium cranioplasty and may reduce the risk of surgical site complication. Randomized, prospective comparisons of cement cranioplasty to traditional techniques are warranted.
