We assessed the efficacy of "only fixation" as treatment for cervical radiculopathy. ⋯ Instability of the spinal segment is the nodal point of pathogenesis and the primary cause of symptoms related to degenerative spondylotic radiculopathy. The treatment is spinal stabilization. No direct bone or soft tissue decompression is necessary.

Subcortical calculation mapping during parietal glioma surgery in the dominant hemisphere: A case report.
To avoid permanent neurologic deficits and preserve brain function in and near the eloquent area, intraoperative electrical stimulation mapping (IESM) is necessary. However, little is known about how these subcortical regions are involved in calculation processing function in patients with glioma. ⋯ In this report, IESM performed during awake surgery in a subcortical site demonstrated a crucial role played by the dominant parietal lobe in calculation.

To analyze treatment of microvascular decompression using the retrosigmoid approach (RA) in primary trigeminal neuralgia and hemifacial spasm using preoperative images combined with intraoperative microscopic navigation to avoid unnecessarily opening the mastoid air cells (MACs). ⋯ Image processing and intraoperative microscopic navigation can avoid unnecessarily opening MACs and might reduce postoperative cerebrospinal leakage and scalp infection after RA craniotomy.

To evaluate the stability of multiple rod-connector construct designs using a mechanical 4-point bending testing frame. ⋯ Our data indicate that the design, number, and placement of rod connectors have a significant impact on the bending stiffness of a surgical construct. Such mechanical data may influence construct design in primary and revision surgeries of the cervical spine and cervicothoracic junction.

Unfamiliarity with the morphometry of the assimilated C1 lateral mass (C1LM) could make screw placement dangerous. In the present study, we defined the morphometric dimensions of the occipitalized C1LM to provide surgeons with valuable information for preoperative planning. ⋯ Although the hypoplastic C1LM brings limitations to screw insertion to some extent, it is still broad enough to accommodate a screw safely in both female and male patients. Considering the irregularity of the C1LM in patients with OA, the preoperative imaging assessment is critical, and C1LM screw placement should be performed individually.
