Object. In this report the author presents surgery-related outcomes after application of a new technique. A posterior microendoscopic laminoforaminotomy was used for the surgical treatment of unilateral cervical radiculopathy secondary to intervertebral disc herniations and/or spondylotic foraminal stenosis. The results of this procedure are compared with those achieved using traditional laminoforaminotomy and anterior cervical discectomy with or without fusion. Methods. One hundred consecutive patients who experienced unilateral cervical radicular syndromes, which were refractory to conservative therapy, and in whom imaging studies had confirmed lateral canal or foraminal compression, underwent surgical treatment. An endoscopy-assisted posterior laminoforaminotomy was performed using a microendoscopic visualization system for removal of herniated disc and foraminal decompression while the patient was in the sitting position. Excellent or good results were obtained in 97 patients, who returned to their preoperative employment and baseline level of physical activity. One patient returned to work but was unable to perform at baseline level; two patients returned to prior sedentary work but continued to have some activity-related pain and paresthesias. Two patients reported experiencing intermittent paresthesias or numbness, but this did not limit their activities. There were two cases of dural punctures, one case of superficial wound infection, and no deaths. Conclusions. The microendoscopic posterior laminoforaminotomy is an effective alternative for the treatment of unilateral cervical radiculopathy secondary to lateral or foraminal disc herniations or spondylosis. In this group of patients, it is preferable because it does not require the sacrifice of a cervical motion segment, has a low incidence of complications, and is associated with a much quicker return to unrestricted full activity than that obtained with other techniques.

Object. Cervical radiculopathy caused by either soft herniated disc material or foraminal stenosis is a common problem. Anterior and posterior surgical approaches are commonly used to decompress the nerve root. The authors undertook a study to establish the feasibility of performing a microendoscopic posterior approach for cervical foraminotomy in the clinical setting. Methods. The authors performed an endoscopic posterior foraminotomy technique in which they used a rigid endoscope, in both a cadaver model and in three clinical cases, including one in which a multiple-level procedure was undertaken. Postoperatively, all patients returned to functional work status within 4 weeks. The mean length of hospitalization was 1.3 days. Conclusions. The advantages to this technique include improved intraoperative visualization, a smaller incision, and significantly less postoperative discomfort compared with a traditional keyhole approach.

✓ 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.

✓ Since 1997, cervical endoscopic laminoforaminotomy (CELF) has been an effective and safe treatment option for unilateral cervical radiculopathy secondary to disc herniation or foraminal stenosis. The development of the surgical technique is reviewed and recent outcomes discussed. Its impact is addressed in relation to the patient and surgeon.

✓ 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 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.

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.
