✓ The authors report a new technique for en bloc petrosectomy using a Gigli saw as an alternative to drilling the petrous bone in the combined supra- and infratentorial approach or the transpetrosal—transtentorial approach. It is simple and easy and avoids postoperative cosmetic deformity. This technique has been performed in 11 petroclival lesions without injuring the semicircular canals, the cochlea, or the facial nerve.

✓ The author describes a new technique for exposure of the cervical spine laminae in which the attachments of the semispinalis cervicis and multifidus muscles to the spinous processes are left untouched. It provides a conservative exposure through which a diverse range of posterior cervical surgeries can be performed. In contrast to conventional cervical approaches, none of the muscular attachments to the spinous processes is compromised. In this paper the author describes the technical details and discusses the applications of the procedure.

✓ A new technique for monitoring intracranial pressure is presented. It is based on a hollow screw in the skull whose tip projects through the dura into the subarachnoid space. The screw can be easily inserted under local anesthesia. Pressure is monitored isovolumetrically by connecting the screw to a transducer. The system can be calibrated in situ and has been successfully used in 56 patients during a 6-month period.

✓ In 1976, Fasano, et al., described a new technique of posterior rhizotomy for treatment of spasticity. They stimulated electrically fascicles of the posterior roots in spastic patients and found that some fascicles responded to stimulation with tonic muscle contractions. They cut these fascicles, preserving those with a weaker or no reaction. The present authors have used a fairly similar technique in the treatment of eight patients with spasticity of the legs and one patient with spasticity of the arm: all fascicles of the posterior roots T12-S1 and C6–8, respectively, were stimulated electrically during surgery under general anesthesia. Approximately 60% to 80% of the fascicles responded to stimulation with tonic muscle jerks, and only these fascicles were cut. All nine patients showed a good reduction of spasticity. The residual cutaneous and joint sensation remained unchanged. Motility of the limbs usually improved.

✓ The authors report the case of a patient with subarachnoid hemorrhage in whom an intracranial dural arteriovenous malformation coexisted with a spinal arteriovenous malformation. The latter was considered to be the source of the hemorrhage by clinical and radiographic criteria. It is concluded that patients with subarachnoid hemorrhage who show no suitable intracranial source for their bleed in some instances should be investigated for a spinal origin of hemorrhage.

✓ Two cases of spinal arteriovenous malformation (AVM) are reported because of a previously unobserved clinical feature: recurrent transient postprandial paresis of the legs. The authors believe the paresis was caused by chronic shunting of blood away from the cord and into the low-resistance AVM. Symptomatic cord ischemia might then be precipitated by vasodilatation in other areas of the body such as the splanchnic, brachial, or uterine vessels. We believe that in some instances this mechanism should be considered as an explanation for episodic neurological deficits seen in association with spinal AVM's.

✓ The authors report a new technique to anchor deep brain stimulation electrodes using a titanium microplate. This technique has been safely used to secure 20 quadripolar deep brain stimulation electrodes implanted for movement disorders (18 electrodes) and pain (two electrodes). Twelve electrodes were implanted in the thalamus, four in the subthalamic nucleus, and four in the pallidum. No electrode migration or rupture occurred, and all electrodes have been shown to work properly after internalization of the system.

✓ A new technique for performing a posterior rib and multistranded cable atlantoaxial fusion in children is described. The technique has been used successfully, in two patients 22 and 18 months of age, respectively. In both cases, fusion was used to augment C1–2 transarticular screw fixation, and solid arthrodesis was achieved without a halo orthosis.
