This bibliography is a continuation of those previously published in Teaching of Psychology (e.g., Berry & Daniel, 1984; Fulkerson & Wise, 1987; Johnson & Schroder, 1997; Wise & Fulkerson, 1996). We maintained similar search methods and criteria for inclusion that were used in previous bibliographies. We also continued the cumulative numbering of the items. To help the reader locate relevant articles, we arranged items into a small number of subject categories. Generally, if fewer than three items fell into a specific subject category they were relegated to a category labeled miscellaneous.
Microendoscopic Discectomy Compared with Standard Microsurgical Discectomy for Treatment of Uncontained or Large Contained Disc Herniations
Authors: Schizas Constantin , Tsiridis Elefterios , Saksena Joyti 
Published: October 2005

Abstract

OBJECTIVE:
Minimally invasive spinal techniques have been developed for years in an attempt to minimize trauma. However, most endoscopic techniques have been unable to address uncontained or large contained disc herniations. The aim of this prospective study was to compare the results of microendoscopic discectomy (MED) and microsurgical discectomy in the treatment of patients with uncontained or large contained disc herniations.

METHODS:
An independent observer reviewed the treatment of 28 patients. The study group included 14 consecutive patients who underwent MED and 14 consecutive patients who underwent microsurgical discectomy for radicular pain secondary to uncontained or large contained disc herniations during the same period. Patients were followed up for an average of 12 months. They were assessed by use of Oswestry disability questionnaire and low back pain outcome score.

RESULTS:
The average outcome score improvement was of clinical significance in both patient groups. No difference in the scores was found between the two groups. Patients in the MED group required less postoperative analgesia during their stay. One patient in the MED group had a dural tear.

CONCLUSION:
MED is at least as effective as microsurgical discectomy for treatment of uncontained or large contained disc herniations, although the advantages over the open technique are short lived and did not reach significance. Nonetheless, for the surgeon accustomed to endoscopic techniques, MED seems to be a safe procedure.

Published: October 2005

Abstract

OBJECTIVE:
Extradural or subcutaneous cerebrospinal fluid (CSF) leakage is a common complication after spinal surgery and is associated with the risks of poor wound healing, meningitis, and pseudomeningocele. Numerous methods to prevent postoperative CSF leakage are available, but pressure-tight dural closure remains difficult, especially with synthetic surgical membranes. The efficacy of a novel dural closure technique was assessed by detecting extradural or subcutaneous CSF leakage on magnetic resonance imaging.

METHODS:
The novel dural closure technique using absorbable polyglactin acid sheet and fibrin glue and the conventional procedure using only fibrin glue were evaluated retrospectively by identifying extradural or subcutaneous CSF leakage on magnetic resonance imaging scans in the acute (2–7 d) and chronic (3–6 mo) postoperative stages after spinal intradural surgery in 53 patients.

RESULTS:
The incidence of extradural and subcutaneous CSF leakage was significantly lower (P &lt; 0.05) in the acute (20%) and chronic (0%) stages using polyglactin acid sheet and fibrin glue in 15 patients compared with that in the acute (81%) and chronic (24%) stages using only fibrin glue in 38 patients. One patient in the fibrin glue-only group required repair surgery for cutaneous CSF leakage.

CONCLUSION:
The combination of polyglactin acid sheet and fibrin glue can achieve water-tight closure after spinal intradural surgery and can minimize the risk of intractable postoperative CSF leakage. This simple, economical technique is recommended for dural closure after spinal intradural surgery.
Comparison of Magnetic Tracking and Optical Tracking by Simultaneous Use of Two Independent Frameless Stereotactic Systems
Authors: Mascott Christopher R. 
Published: October 2005

Abstract

OBJECTIVE:
The goal of this study was to compare the calculated accuracy and the true surgical accuracy of a magnetic and an optical tracking system at surgical registration and during surgery.

METHODS:
Two Food and Drug Administration-approved, commercially available frameless stereotactic systems were used simultaneously in 70 surgical cases. The Compass Cygnus-PFS system (Compass International, Rochester MN) uses magnetic field referencing and tracking. The StealthStation (Medtronic SNT, Louisville, CO) uses optical referencing and tracking. Registration was performed for each of the systems using adhesive fiducial markers, cranial-implanted markers, anatomic landmarks, or a combination thereof. Preoperative imaging consisted of volumetric computed tomography, magnetic resonance imaging, or both. Calculated accuracy was given by each of the systems as the root mean square after registration. Surgical accuracy was assessed by comparing the anatomic accuracy of each system with a number of recognizable intraoperative anatomic landmarks

RESULTS:
Calculated accuracy (root mean square) was 1.4 ± 0.6 mm using the magnetic system and 1.4 ± 0.8 mm using the optical tracking system. In the 42 patients with implanted cranial fiducials, the calculated accuracies were 1.0 ± 0.5 mm (magnetic) and 0.9 ± 0.4 mm (optical). True surgical accuracy was considered good (3 mm or less) in both systems in 60 of 70 patients. In two patients, neither system was accurate. In eight patients, one of the two systems was considered inaccurate. Of these, the magnetic system was considered inaccurate three times and the optical system five times.

CONCLUSION:
Magnetic referencing and tracking was found to be comparable with optical tracking both with regard to calculated and true surgical accuracy. Interference from metal objects in the magnetic field was seen rarely.
Techniques for Aspirating Bone Marrow for Use in Spinal Surgery
Authors: Kitchel Scott H. , Wang Michael Y. , Lauryssen Carl L. 
Published: October 2005

AbstractOBJECTIVE:The osteogenicity of bone marrow has been well documented in the literature. The use of bone marrow as a source of osteoprogenitor cells for spinal fusion surgery is increasing. Improper aspiration technique can lead to dilution of bone marrow and a subsequent reduction in osteoprogenitor cells. Therefore, correct aspiration technique is imperative to the successful use of bone marrow with various grafting combinations.METHODS:The authors describe techniques for aspirating bone marrow from the anterior and posterior iliac crest, as well as vertebral body aspiration. The use of selective cell retention to increase the number of osteoprogenitor cells populating a graft is also described.RESULTS:Complications from bone marrow aspiration can occur, but the incidence is rare.CONCLUSION:Clinical studies currently under way will answer the question of bone marrow efficacy in spinal fusion surgery.
Tumors of the Lateral and Third Ventricle: Removal under Endoscope-assisted Keyhole Conditions
Authors: Charalampaki Patra , Filippi Ronald , Welschehold Stefan , Conrad Jens , Perneczky Axel 
Published: October 2005

Abstract

OBJECTIVE:
Intraventricular tumors usually are managed by approaches and microsurgical techniques that need retraction and dissection of important brain structures. Minimally invasive endoscopic procedures achieve a remarkable alternative to conventional microneurosurgical techniques. Endoscope-assisted microneurosurgery may be a minimally invasive technique with maximally effective treatment. Using the keyhole concept for planning the surgical strategy, the reduction of the brain retraction is achieved, which is one of the main benefits of this technique.

METHODS:
We treated 35 patients (16 female patients and 19 male patients) with tumors in the lateral (n = 8) and the third (n = 27) ventricle. Patient age at the date of surgery ranged from 5 to 73 years. The follow-up period ranged from 6 to 83 months. The tumors were operated on using transcortical, transcallosal, or suboccipital transtentorial or infratentorial supracerebellar approaches after precise planning of the skin incision, the trephination, and the trajectory to the center of the tumor, performed earlier with a magnetic resonance imaging scan.

RESULTS:
Total removal of the tumor was achieved in 28 patients (78.5%). In 2 patients (6.5%), recurrent tumor occurred. In 5 patients (15%), parts of the tumors remained because of infiltration of eloquent areas. Overall clinical improvement was achieved in 31 patients (87%). Three patients (10%) were unchanged and 1 patient (3%) deteriorated.

CONCLUSION:
Endoscope-assisted keyhole neurosurgery seems to be a safe method of removing tumors in all regions inside the ventricular system with a low risk of permanent neurological deficits. The exact surgical corridor planning on the basis of the keyhole strategy offers less traumatic exposure of even deep-seated endoventricular tumors.
Motor Evoked Potential Monitoring during Cerebral Aneurysm Surgery: Technical Aspects and Comparison of Transcranial and Direct Cortical Stimulation
Authors: Szelényi Andrea , Kothbauer Karl , de Camargo Adauri Bueno , Langer David , Flamm Eugene S. , Deletis Vedran 
Published: October 2005

Abstract

OBJECTIVE:
This study evaluates technical aspects, handling, and safety of intraoperatively applied transcranial electrical stimulation (TES) and direct cortical stimulation (DCS) for eliciting muscle motor evoked potentials (mMEPs) during cerebral aneurysm surgery.

METHODS:
In 119 patients undergoing cerebral aneurysm surgery, mMEPs were evoked by a train of five stimuli with individual pulse duration of 0.5 milliseconds, a repetition rate of 2 Hz, and constant current anodal stimulation. The maximal stimulation intensity was 240 mA for transcranial and 33 mA for direct stimulation. mMEPs were recorded continuously from the abductor pollicis brevis, from tibial anterior muscles bilaterally, and from the biceps brachii and extensor digitorum communis muscles contralateral to the side operated on.

RESULTS:
In 118 (99%) of 119 patients, transcranially evoked mMEPs were monitorable for the vascular territory of interest. DCS was performed successfully in 95 (95%) of 100 patients. In 86 (99%) of 87 patients with internal carotid artery, middle cerebral artery, or posterior circulation aneurysms, mMEPs from upper-extremity muscles were obtained with DCS. In 11 (55%) of 20 patients with anterior communicating artery, anterior cerebral artery, or pericallosal aneurysms, mMEPs from the lower-extremity muscles could be recorded. The incidence of seizures was 0.84% for TES and 1% for DCS. Minor and inconsequential subdural bleeding after positioning of the strip electrode occurred in 2%.

CONCLUSION:
The cogent comprehensive combination of transcranial and direct cortical electrical stimulation allows for the continuous mMEP monitoring of the cerebral vascular territory of interest in 99% of the patients with cerebral aneurysms. Unwarranted effects of electrode placement and stimulation are rare and without clinical consequences.
Piezoelectric Bone Surgery: A Revolutionary Technique for Minimally Invasive Surgery in Cranial Base and Spinal Surgery? Technical Note
Authors: Schaller Bernhard J. , Gruber R , Merten H A. , Kruschat Thomas , Schliephake H , Buchfelder Michael , Ludwig H C. 
Published: October 2005

Abstract

OBJECTIVE:
Piezoelectric surgery represents an innovative, ultrasonic surgery technique for performing a safe and effective osteotomy or osteoplasty that contrasts with the traditional hard and soft tissue management methods with rotating instruments.

METHODS:
Because of its physical and mechanical properties, the definitive clinical advantage of piezoelectric bone surgery with regard to precision cutting lies in the sparing of vital neurovascular bundles or general soft tissue and better visualization of the surgical field, thus suggesting its great safety. Piezoelectric bone surgery has been previously described only in oral and maxillofacial operative procedures in adults.

RESULTS:
Five children between the age of 6 and 84 months were operated on for craniosynostosis, tethered cord, and an extraconal intraorbital tumor. The usefulness of piezoelectric bone surgery during neurosurgical procedures is presented for these cases. This technique is especially recommended when there are anatomic difficulties because of poor intraoperative visibility or the presence of delicate anatomic structures.

CONCLUSION:
The present preliminary report (comprising illustrative case reports) demonstrates and introduces for the first time the utility of piezoelectric bone surgery in cranial base and spinal surgery in children. Until now, there has been no documented neurosurgical experience of this technique even in adults.
Thoracoscopically Guided Transaxillary Resection of Adjoining Intercostal Plexiform Neurofibromas: Review of Mosaicism in Neurofibromatosis: Technical Note
Authors: Salazar Fortino , Machado Andre , Murthy Sudish , Boulis Nicholas M. 
Published: October 2005

Abstract

OBJECTIVE AND IMPORTANCE:
The present article describes a rare presentation of Type I neurofibromatosis (NFI) involving adjoining intercostal plexiform neurofibromas, as well as the novel use of thoracoscopy to guide surgical resection. This presentation highlights the manner in which NFI may affect selective regions of the body disproportionately through genetic mosaicism.

CLINICAL PRESENTATION:
A 40-year-old man had intractable neuropathic anterior right chest wall pain in the distribution of T2 and T3. Magnetic resonance imaging and computed tomography of the chest revealed masses deep to the second and third ribs in the axilla. Biopsy of a subcutaneous nodule in the right chest wall revealed a small neurofibroma. An extensive workup revealed no masses outside the region of the right chest wall and no stigmata of NFI.

INTERVENTION:
The patient underwent right-sided thoracoscopy for identification of the intrathoracic neurofibromas and placement of spinal needles to localize the anterior and posterior extent of the masses. These landmarks were used to guide a transaxillary approach to third rib resection and nerve-sparing neurofibroma resection.

CONCLUSION:
Isolated adjoining intercostal plexiform neurofibroma is a unique presentation of mosaic NFI. Because of its limited penetrance, this variant may present as a regional pain syndrome. Thoracoscopy can be used effectively to guide intercostal nerve sheath tumor resection.
Surgical Management of Osseous Hemangioblastoma of the Thoracic Spine: Technical Case Report
Authors: Steinmetz Michael P. , Claybrooks Roderick , Krishnaney Ajit , Prayson Richard A. , Benzel Edward C. 
Published: October 2005

Abstract

OBJECTIVE AND IMPORTANCE:
Spinal hemangioblastomas usually occur as isolated, intramedullary, central nervous system masses, often as a component of von Hippel-Lindau syndrome. They may occasionally occur extradurally and give the appearance of vertebral hemangioma. Rarely, they may be purely osseous lesions. The surgical management of these lesions has not been elaborated. We present a case and discuss the management of multilevel osseous hemangioblastoma of the thoracic spine.

CLINICAL PRESENTATION:
A 50-year-old woman with a history of thoracic hemangioblastoma 3 years earlier presented with progressive paraparesis. Imaging revealed circumferential tumor involvement of T7 to T9, inclusive. There was severe spinal cord compression.

INTERVENTION:
The patient underwent surgery via a bilateral lateral extracavitary approach to the tumor. This permitted a complete spondylectomy of T7, T8, and T9; complete tumor removal; and decompression of the spinal cord. Pathological analysis confirmed hemangioblastoma. The spine was reconstructed with an interbody expandable cage and pedicle screw fixation, all placed via the dorsal approach. The patient improved neurologically after the operation.

CONCLUSION:
Although extremely rare, hemangioblastomas may occur in a purely osseous location. They may resemble vertebral hemangioma. Treatment should include aggressive surgical removal, although arduous, if appropriate. A bilateral lateral extracavitary approach is ideal for complete spondylectomy. With this technique, ventral and dorsal reconstruction of the spine through the same incision is possible.
Far-lateral Approach to the Craniocervical Junction
Authors: Lanzino Giuseppe , Paolini Sergio , Spetzler Robert F. 
Published: October 2005

Abstract
THE FAR-LATERAL APPROACH is an extension of the standard suboccipital approach, designed to maximize exposure of the lateroventral craniocervical junction. Following a basic principle of cranial base surgery, the angle of view is increased by bone removal. Bone removal involves the most lateral part of the inferior occipital squama and the posterior arch of C1. Drilling of various portions of the occipital condyle further increases the exposure. Transposition of the vertebral artery is seldom required. The far-lateral approach allows a tangential, unobstructed view of the lateroventral cervicomedullary area and can be applied effectively to manage with a heterogeneous spectrum of pathological lesions involving this area. The technical aspects of the procedure are briefly illustrated in this report.

Authors: Flaherty Alice W. , Williams Ziv M. , Amirnovin Ramin , Kasper Ekkehard , Rauch Scott L. , Cosgrove G Rees , Eskandar Emad N. 
Published: October 2005

Abstract

OBJECTIVE AND IMPORTANCE:
Medical treatment of Tourette syndrome is often ineffective or is accompanied by debilitating side effects, therefore prompting the need to evaluate surgical therapies.

CLINICAL PRESENTATION:
We present the case of a 37-year-old woman with severe Tourette syndrome since the age of 10 years. Her symptoms included frequent vocalizations and severe head and arm jerks that resulted in unilateral blindness. Trials of more than 40 medications and other therapies had failed to relieve the tics.

INTERVENTION:
We implanted bilateral electrodes in the anterior limb of the internal capsule, terminating in the vicinity of the nucleus accumbens. At 18-month follow-up, optimal stimulation continued to lower her tic frequency and severity significantly.

CONCLUSION:
Our findings suggest that stimulation of the anterior internal capsule may be a safe and effective procedure for the treatment of Tourette syndrome.
Extradural Motor Cortex Stimulation in Advanced Parkinson's Disease: The Turin Experience: Technical Case Report
Authors: Pagni Carlo Alberto , Zeme Sergio , Zenga Francesco , Maina Raffaella 
Published: October 2005

Abstract

OBJECTIVE AND IMPORTANCE:
At our institution, extradural motor cortex stimulation (EMCS) has recently been applied for treating Parkinson's disease symptoms. We report our results and review the literature supporting this application of EMCS.

CLINICAL PRESENTATION:
Since 1998, six patients affected by advanced Parkinson's disease and not fulfilling inclusion criteria for deep brain stimulation underwent EMCS.

INTERVENTION:
A quadripolar electrode was introduced in the extradural space over the motor cortex, opposite to the side on which parkinsonian symptoms had begun. Bipolar chronic electrostimulation was delivered at 2.5 to 6 V, 150 to 180 microseconds, and 25 to 40 Hz. Preoperative and postoperative clinical status was assessed by the Unified Parkinson's Disease Rating Scale (UPDRS) and recorded on videotapes. The follow-up of this series varied from 4 months to 2.5 years. After EMCS, the overall UPDRS score decreased by 42 to 62%; Section III UPDRS score (motility evaluation) by 32 to 83%; and Section IV UPDRS score (therapy complications) by 100% in two patients, by 50 to 67% in four patients, and by 33% in one patient. l-Dopa therapy was reduced by 11 to 33% in three patients and by 70 to 73% in the other two patients. No postoperative complications or negative side effects of electrostimulation were recorded, except for a misplacement of the electrodes in one patient.

CONCLUSION:
Unilateral EMCS relieves, at least partially, but sometimes dramatically, the whole spectrum of symptoms in advanced Parkinson's disease. l-Dopa may be reduced up to 70%. The symptoms of long-term l-dopa syndrome are usually markedly improved. The neurophysiological mechanisms involved are still under debate. Our clinical experience adds favorable data to enlarge the series of parkinsonian patients treated by EMCS.
