Evolutions in cranioplasty have allowed for the creation of customized implants via advances in 3-dimensional (3D) printing technology, although the high cost associated with this technique presents a barrier for low-income countries. Through an international collaboration, our team in Da Nang, Vietnam is able to create low-cost, customized titanium implants for patients with skull defects. We discuss the details of our collaboration and present our experience with this procedure. ⋯ Cranioplasty using customized titanium implants yields excellent results for patients with skull defects, demonstrating the practicality of this technique for cranioplasty in low-income countries. Our experience highlights the importance of ongoing international collaboration to improve neurosurgical care in these countries.

The aim of this article was to study the outcome of patients who underwent cranioplasty with cryopreserved autologous bone after decompressive craniectomy. ⋯ The outcome after autologous cranioplasty is a multifactorial process, which is modulated by patient-related, surgery-related, and bone-related factors.

We used a data-driven methodology to decrease the departmental surgical site infection rate to a goal of 1%. ⋯ The findings highlight the importance of systematically investigating areas of gap in existing clinical practice and quality improvement projects to increase patient safety and enhance the value of care delivered to neurosurgical patients.

The posterior spinal arteries (PSAs), branches of the intracranial segment of the vertebral artery or posterior inferior cerebellar artery, run bilaterally along the spinal cord and are integral to the blood supply primarily to the posterior one third of this structure. However, a less well-described distribution of the PSAs is their supply to the posterior medulla. The purpose of this study is to examine the medullary branches of the PSA anatomically. ⋯ Physicians who interpret imaging of the craniocervical junction, in particular arteriograms, should be aware of ascending medullary branches arising from the anterior spinal artery. Additionally, neurosurgeons operating this region must be careful in dissecting over the posterior medulla and manipulating the cerebellar tonsils, as in telovelar approaches to the fourth ventricle, in order to avoid iatrogenic injury to these vessels. Additionally, variable stroke patterns involving the vertebral artery or posterior inferior cerebellar artery might include ischemia to the medulla oblongata via PSA branches, and this anatomy should be kept in mind by interventionalists, radiologists, and neurologists alike.

Rheumatoid arthritis (RA) is a systemic disease with prominent musculoskeletal manifestations that is associated with increased morbidity and mortality in patients undergoing cervical spine surgery; however, few studies have specifically examined postoperative outcomes in patients with RA following lumbar surgery. The aim of this study was to evaluate whether patients with RA who underwent posterior lumbar fusion experienced increased postoperative complications and economic burden compared with patients without RA. ⋯ Preexisting RA may increase risk for short-term postoperative medical complications following posterior lumbar fusion, specifically infectious events. In addition, patients with RA have higher rates of subsequent reoperation following index surgery. Patients with RA be should counseled regarding these risks.
