Review Case Reports
Extreme proximal junctional kyphosis-a complication of delayed lambdoid suture closure in Hajdu-Cheney syndrome: a case report and literature review.
To describe the manifestations, surgical treatment, and potential complications of Hajdu-Cheney syndrome (HCS), and the management of these complications. ⋯ In patients with HCS and other conditions with delayed suture closure, the surgeon must be cognizant of the presence of mobility at the suture lines, and consider extending the fusion construct anteriorly over the skull vertex up to the frontal bones. Because of significant osteoporosis in these syndromes, multiple fixation points and augmentation with bone graft are important principles.

The use of conventional percutaneous endoscopic lumbar discectomy (PELD) for high-grade down-migrated lumbar disc herniation medial to the pedicle via the transforaminal route can result in less favorable outcomes. We report a new PELD technique for the treatment of high-grade down-migrated lumbar disc herniation via a facet process and pedicle-complex approach. ⋯ PELD via a facet process and pedicle-complex approach may be an option for high-grade, down-migrated lumbar disc herniation with completely sequestrated nucleus pulposus.

To report the case of a pediatric patient with intramedullary spinal aneurysm. ⋯ To our knowledge, this is a first report of an intramedullary spinal cord aneurysm at the cervical-thoracic junction in a pediatric patient. Careful observation after initial symptoms followed by surgical intervention was favorable in this case.

To study the known or suspected risk factors for sciatica: Tallness, overweight, smoking, leisure-time physical exercise, self-reported health and occupation, and how they predict hospitalizations due to sciatica. Only a few cohort studies have previously focused on the risk factors for sciatica. ⋯ Physically demanding work is a strong risk factor for sciatica. Leisure-time physical activity seems to protect men against sciatica, while overweight is a risk factor among women. However, occupation substantially modifies these associations.

Review Case Reports
Intradural cervical chordoma with diffuse spinal leptomeningeal spread: case report and review of the literature.
Chordoma is a low-grade malignant bone tumor derived from embryonic notochord remnants along the axial skeleton. About 50% of chordomas occur in the sacral vertebrae and 35% in the skull base. Most chordomas are extradural and cause extensive bone destruction. Intradural spinal tumors without bone involvement are rare. ⋯ An intradural spinal chordoma is difficult to distinguish from a neurogenic tumor by imaging. When the lesion is dumbbell-shaped, it is easily misdiagnosed as a schwannoma. In the present case, the tumor was intradural and located at the level of the C6 and C7 vertebrae. Preoperative diagnosis was difficult, and the final diagnosis required pathological examination.
