To compare vertebral morphology among patients with adolescent idiopathic scoliosis (AIS), patients with Chiari I malformation (CMS)-associated scoliosis, and normal control subjects, with the goal of determining the role of anterior column overgrowth in the development of AIS. ⋯ Faster growth of the anterior spinal column was confirmed by longer vertebral bodies and shorter pedicles in both patient groups. Relative anterior spinal overgrowth of the thoracic spine is not involved in the initiation of AIS, and the abnormal growth pattern of the vertebral body in AIS might be a secondary change to the spinal curve.

Arterial pseudoaneurysms of the neck are rarely reported in the pediatric population and no dedicated large series are available. Trauma and infection are the most common causes for these aneurysms, with congenital and collagen vascular disorders being the less common causes. These lesions can be life threatening, especially when they present with bleeding or airway compromise. ⋯ Endovascular means of treatment for pediatric neck aneurysms is relatively simple and safe. Although parent vessel sacrifice is the gold-standard management, vessel-preserving strategies can be tried in select cases with favorable anatomy.

To identify clinical and radiographic features of subtypes of acute proximal junctional failures (PJFs) following correction surgery for degenerative sagittal imbalance. ⋯ Patients with acute PJFs had lower T-score and BMI. Each subtype of PJFs had different clinical and radiographic features. Although BMI and T-score were associated with all PJFs, each subtype may have different risk factors. Identifying risk factors for each subtype of acute PJFs may help avoid it.

Dexamethasone is a standard treatment for cerebral edema after brain tumor surgery. However, its side effects can negatively impact the quality and safety of care provided to patients. Sparse evidence exists in the literature regarding postoperative steroid dosing to guide clinicians. The objective of this study was to determine if a new reduced exogenous steroid taper (REST) protocol would effectively treat postoperative cerebral edema while reducing the incidence of steroid-related side effects including diabetes, hypertension, and insomnia. ⋯ A reduced steroid taper after brain tumor surgery significantly reduced the incidence of hypertension without increasing LOS or 30-day readmissions compared with controls treated with a high-dose taper.

We report a retrospective analysis of hardware failure in patients requiring instrumentation for spinal metastasis. ⋯ The rate of hardware failure in this cohort was 13.8%, although operative revision rate was 3.4%. Spinal instrumentation in patients with poor preoperative functional status or multiple myeloma may be more likely to develop instrumentation failure.
