1–6 are not discussed. We believe that unilateral sciatica, sufficient to prevent work or sleep, justifies surgery, in contrast to back ache alone which is often found to be amenable to nonoperative measures. In our experience, spondylolisthesis with unilateral sciatica indicates a superimposed disc and its treatment is basically the same as for simple ruptured disc. Technique Myelography We use myelography where doubt exists after consideration of the history and physical findings; 6 to 9 ml of Pantopaque are injected and completely removed through a

apparatus, thereby decreasing the risk of retraction-related injury that is often associated with transcranial approaches. 19 , 26 Although the benefits of the endoscopic technique for properly selected patients are clear, neurosurgeons have been slow to adopt it because of the steep operator’s learning curve. 20 , 34 , 40 To that end, we present this technical descriptive report and detailed illustrations of the technical nuances recommended for endonasal endoscopic resection of craniopharyngiomas.

formation because of the interference with CSF flow. However, reconstruction of the subarachnoid space also permits the insertion of a shunting tube into the syrinx at the same time. 1 , 7 , 9 We hypothesized that reconstruction of the subarachnoid channels would reestablish CSF flow, thereby addressing the underlying cause of the syrinx formation. Accordingly, we performed a new type of surgical technique that we named subarachnoid–subarachnoid bypass (S–S bypass) to reestablish the normal CSF circulation around the spinal cord. The purpose of this study was to

we can improve the diagnostic yield of nerve biopsy in proximal or asymmetrical neuropathy by performing a targeted proximal biopsy. Targeting the most pathologically involved segment of the nerve based on meticulous preoperative planning may be considered to guide the choice of site of the biopsy and maximize its diagnostic accuracy. 5 To a large extent this technique has been facilitated by a wide utilization of new high-resolution imaging techniques. 3 , 5 , 11 Such guidance allows us to improve selectivity of a nerve biopsy site. 4 , 5 , 9 , 19 Our group

. The nerve was divided as it started thinning off, approximately 5 cm from the superior angle of scapula, and was delivered to the surface. The distance between the SAN and SSN measured 12 cm. A 13.5-cm-long sural nerve graft, tunneled subcutaneously, was interposed between the ends of the SAN and SSN ( Fig. 1 ). A third vertical midline incision helped in the retrieval of the nerve graft. Figure 2 shows a schematic representation of this technique. Nerve coaptations were carried out with 10-0 nylon suture under a surgical microscope. Skin incisions were closed

I n 1981, Roy-Camille and colleagues 5 introduced the techniques that allow complete removal of thoracic and lumbar vertebrae using a wide bilateral posterior approach and of tumors involving a thoracic vertebral body. Tomita et al. 6 introduced a new technique for the posterior total (“en bloc”) spondylectomy of thoracic vertebrae that would permit resection of the tumor and prevent its local dissemination during surgery. The Tomita technique was based on a posterior median approach extended bilaterally to expose the costovertebral joints. In brief, it

States. 17 , 18 The aim of ICP monitoring is to identify all those patients in need of intervention to avoid secondary brain injuries. 3 , 5 The standard method of ICP monitoring in children is still the placement of an external intraventricular catheter with an ICP probe. 5 , 10 However, this is an invasive technique which carries the risk of infection, hemorrhage, and system malfunction. Hemorrhage occurs in approximately 7%–11% of patients after insertion of an invasive device for ICP measurement, 1 , 4 , 12 and infection rates have been reported to range

, 24 , 25 , 28 , 29 have been attempted. At most tertiary centers, preoperative embolization followed by microsurgical resection is the preferred treatment. We retrospectively reviewed the clinical and radiographic outcomes of our series of spinal glomus AVMs while highlighting a pial resection technique that minimizes parenchymal dissection. This technique, which provides subtotal AVM nidus resection, effectively devascularizes glomus AVMs, as confirmed on postoperative angiography.

T he versatility of endoscopic endonasal surgery for approaching suprasellar lesions has been increasingly recognized over the past decade. 5 Despite initial trepidation about manipulating supradiaphragmatic areas of pathology through the nose, a purely endoscopic endonasal approach to purely suprasellar lesions such as meningiomas of the anterior fossa has been demonstrated to be both effective and safe in the hands of experienced surgeons. 6 , 9 , 15 , 21 Since the first descriptions of this technique for resection of anterior fossa meningiomas that

augment pedicle screws, it can significantly increase the rigidity, stiffness, and strength of the screw. 3 , 8 Various systems and techniques for using cement to augment osteoporotic bone have been developed, such as expandable screws, partially or fully cannulated screws, 9 , 12 and direct 2 or indirect injections. In recent years, percutaneous pedicle screw fixation, which limits muscular damage and intraoperative bleeding, decreases postoperative pain and accelerates postoperative recovery. 7 However, neither a practical and reliable technique nor an optimal
