Multicenter Study
Outcomes of subdural versus subperiosteal drain after burr-hole evacuation of chronic subdural hematoma: a multicenter cohort study.
Although the use of a postoperative drain after burr-hole evacuation of chronic subdural hematoma (CSDH) is known to improve surgical outcomes, the superiority of subdural over subperiosteal drains has not been firmly established. Evidence comparing these 2 drain types is largely restricted to single-center series with limited numbers. Using a multicenter cohort study, we aimed to show noninferiority of subperiosteal drains vis-à-vis subdural drains after burr-hole evacuation of CSDH. ⋯ Outcomes of subdural and subperiosteal drains after burr-hole craniostomy for CSDH are largely equivalent based on our findings.

Review Case Reports
Extraforaminal vertebral artery until the C2 transverse foramen in Down syndrome patient affected by atloaxial subluxation. First observation and review of the literature.
Patients with Down syndrome (DS) have an increased incidence of multisystem disorders, like cardiovascular, neurologic, gastrointestinal, respiratory, and musculoskeletal disorders. Craniovertebral junction instability is a common illness in DS patients, and they may often be affected by vertebral artery (VA) anomalies. ⋯ We reviewed the literature about the incidence of anatomic variations of the V2 segment in both the general population and the one affected by DS, and although numerous cases of anomalous course, none reported a C2 TF entry point. Ignoring such extremely rare anatomic variation during anterior, posterior, or lateral surgical approach to the cervical spine can lead to inadvertent injury and potentially serious complications like arterial dissection, thrombus, vascular spasm, fistula, pseudoaneurysm, cerebral ischemia, and death.

Review Case Reports
An extradural dumbbell-shaped tuberculoma masquerading as a nerve sheath tumor: Case report and review of the literature.
Spinal tuberculosis has been listed as a rare cause of neuroforaminal widening with only 2 previous reports in the literature. Here, we report the third case of an extradural tuberculoma extending through and expanding the neural foramen closely masquerading as a nerve sheath tumor including, to the best of our knowledge, the first description of magnetic resonance imaging, operative, and histopathology findings. ⋯ This case illustrates that a tuberculoma can have many of the features of a benign neoplasm, such as encapsulation, appearance of a slow rate of growth, and development of necrosis or even cystic degeneration. With the specific findings of entrapped nerve fascicles, we postulate that the lesion represents a nerve sheath tuberculoma rather than spinal tuberculosis of the pedicle or posterior elements. Furthermore, only a lesion of the nerve sheath would have the characteristic dumbbell appearance as it extends through the foramen.

Review Case Reports
Removal of migrating lumbar spine bullet: Case Report and Surgical Video.
Gunshot wounds to the spine are devastating injuries. Rarely, the bullet has been reported to migrate. Migration is associated with progressive neurologic deficits that often improve with bullet removal. The authors report a case of removal of a migrating lumbar spine bullet. This is supplemented by an operative video and a review of the literature. ⋯ Neurosurgical treatment for gunshot wounds remains controversial. Cauda equina or lumbosacral level wounds are often incomplete and may improve with surgical decompression and bullet removal. Migrating bullet fragments throughout the spine and brain lead to worsened neurologic function, which can be reversed by removal. Movement of the bullet during surgery should be expected, and intraoperative fluoroscopy and patient positioning can help to properly localize the bullet and aid in its removal.

Review Case Reports
The Use of Distraction Osteogenesis in the Treatment of Rickets-Associated Craniosynostosis.
Craniosynostosis has a known association with rickets. Because of abnormal bone development and a tendency for patients with rickets to present at an older age than most patients with craniosynostosis, repair may be complicated by inadequate cranial expansion and greater risk of sutural re-fusion. We present 2 cases of rickets-associated sagittal craniosynostosis and show the effectiveness of distraction osteogenesis in the surgical management of this condition. ⋯ Distraction osteogenesis promotes bone growth and cranial remodeling in patients with craniosynostosis caused by rickets. The technique allows for continuous incremental expansion of both bone and scalp tissue. We recommend consideration of distraction osteogenesis in the treatment of older children with severe deformity related to craniosynostosis, including those with rickets.
