The authors describe a modified technique for placement of the C1 lateral mass screw using a Steinmann pin as a guide. This technique minimizes dissection and provides atlantoaxial stabilization during arthrodesis. ⋯ The use of Steinmann pins to guide the placement of C1 lateral mass screws is safe and effective in C1-2 arthrodesis. Limiting dissection minimizes blood loss and injury, maintains efficient operative time, and assists in accurate placement of the screws. Furthermore, with less manipulation and retraction of the C2 nerve root, postoperative occipital neuralgia and the need for C2 root transection are avoided.

Hemangioblastomas with enhanced cyst walls represent a rare radiologic presentation of hemangioblastomas with poor understandings. We aimed to summarize the clinical and radiologic features, important differential diagnosis, surgical strategy, and clinical outcome of this rare entity. ⋯ Hemangioblastomas with enhanced cyst wall possess distinctive radiologic features, and they are frequently misdiagnosed preoperatively. Favorable tumor control can be achieved only when gross total resection of both the tumor nodule and cyst wall are performed. Close follow-up is necessary because of the high recurrence rate in this subset of hemangioblastomas.

Parkinson disease (PD) is a major risk factor during spine surgery, and its frequency is increasing as the population ages. The study aim was to examine the influence of PD specifically on lumbar decompression surgery. ⋯ There is a significantly greater rate of perioperative complications in patients with PD undergoing elective decompression surgery. Although the difference in major complication rates was minimal, minor complications were more frequent in patients with PD.

Intradural epidermoid tumors of the spinal cord are commonly associated with spinal cord dysraphism or invasive procedures. We report the particular relationships between spinal subarachnoid compartments and thoracic intradural-extramedullary epidermoid tumor, highlighting the relevant anatomic changes that may influence microsurgery. ⋯ A thorough knowledge of spinal subarachnoid space anatomy is helpful to distinguish between tumor membranes and arachnoidal planes and to achieve a safe and complete resection to avoid recurrences.

Review Case Reports
Non-traumatic multiple vertebral compression fractures induced by primary hyperparathyroidism: A case report and literature review.
Primary hyperparathyroidism (PHPT) is one of the causes of osteoporosis and is known to increase the fracture risk of bone. However, multiple vertebral compression fracture because of PHPT is extremely rare. ⋯ When a patient has multiple compression fractures without any trauma history and a very low T score, the presence of other underlying diseases should be investigated.
