RESUMEN
BACKGROUND: Epidural steroid injection is widely used to treat the short and long-term symptoms of low back and radicular pain. To the best of our knowledge, the influence of transforaminal epidural steroid injection (TFSI) combined with caudal epidural steroid injection (CESI) on pain intensity, patient satisfaction, and quality of life in lumbar radiculopathy has not been examined. AIM: To evaluate the short and long-term efficacy of TFSI, and TFSI combined with CESI (TFSI + CESI) in patients with lumbar radiculopathy. MATERIALS AND METHODS: We retrospectively examined the records of 104 patients with lumbar radicular pain and L4/5 and/or L5/S1 intervertebral disc disease who underwent TFSI or TFSI + CESI. We compared the pain intensity using a Visual Numeric Scale (VNS), North American Spine Society (NASS) pain satisfaction index, and EuroQol five dimensions (EQ-5D) quality of life scores before intervention, and after 1, 6 and 12 months. RESULTS: In the TFSI group, the mean pre-treatment VNS score was 9.2, which improved to 4.9 after 1 month and to 7.2 after 12 months. In the TFSI + CESI group, the mean pre-treatment VNS score was 9.4, which improved to 2.6 and 4.6 after 1 and 12 months, respectively. Improvement in the VNS scores was significantly higher in the TFSI + CESI group (P < 0.0001 for each). Mean EQ-5D quality of life index in the TFSI group improved from 0.59 in the pre-treatment phase to 0.76 after 12 months of intervention, while it improved from 0.62 in the pre-treatment phase to 0.84 at 12 months of intervention in the TFSI + CESI group. The EQ-5D scores were significantly better in the TFSI + CESI group at 1, 6, and 12 months after the procedure (P = 0.004, 0.036, and 0.042, for 1, 6, and 12 months, respectively). The NASS scores were significantly better in the TFSI + CESI group at 6 and 12 months after the intervention (P = 0.025 and 0.001 for 6 months and 12 months, respectively). CONCLUSION: In patients with lower lumbar radiculopathy, a combined TFSI + CESI technique offers superior short and long-term pain relief, quality of life, and long-term patient satisfaction, than when TFSI is performed alone.

STUDY DESIGN: Analysis of the adjacent-segment fractures in 171 balloon kyphoplasty (BK)-performed patients. OBJECTIVE: The purpose of this study was to investigate the risk factors for new symptomatic vertebral compression fractures (VCF) after BK. SUMMARY OF BACKGROUND DATA: Although there are many studies about the incidence and possible risk factors for occurrence of adjacent-level fractures, there is no consensus on the increased risk of adjacent-level fractures after BK. METHODS: We performed a retrospective analysis of 171 patients treated with percutaneous kyphoplasty. The follow-up period was 41.04±21.78 months. The occurrence of new symptomatic VCF was recorded after the procedure. We evaluated the variables of patient age and sex, the amount of injected cement, the initial kyphotic angle (KA) of VCF, the change of the KA after BK, the severity of osteoporosis, and the percentage of height restoration of the vertebral body. Furthermore, possible risk factors were reported for new symptomatic VCFs. RESULTS: The only 2 factors identified as being significantly associated with adjacent-level fractures were the sex (P=0.001) of the patient and the preoperative KA (P=0.013). The patients with new symptomatic compression fracture had higher initial KA than those without fractures. The female group had higher risk than the male group in occurrence of the new vertebra fractures. The severity of the osteoporosis (low bone mineral density) was not a determinant in occurrence of the new VCF after BK. CONCLUSIONS: If the patients experience severe or mild back pain with higher preoperative KA, especially in the first 2 months, then they deserve detailed radiologic examination. To avoid subsequent fracture in the same or adjacent level, vertebral body should be filled adequately and sagittal balance should be obtained with KA correction. BK alone did not influence the incidence of subsequent VCF.

STUDY DESIGN: Retrospective analyses of 50 patients with lumbar facet syndrome treated with lumbar facet joint neurotomy. OBJECTIVE: To establish the efficacy of lumbar facet joint neurotomy under optimum conditions in selected patients. SUMMARY OF BACKGROUND DATA: With the realization of the significance of facet joints in the etiology of chronic low back pain over the last decade, many studies were conducted about various methods of treating the facet joint syndrome. METHODS: Fifty patients with lumbar facet syndrome with at least 80% pain relief by controlled, diagnostic medial branch blocks underwent lumbar facet joint neurotomy. Before surgery, all were examined carefully both clinically and radiologically and evaluated by visual analog scale (VAS) and descriptive system of health-related quality of life state (EQ5D) measures of pain, disability, and treatment satisfaction. All outcome measures were repeated postoperatively and at 12 months after surgery. RESULTS: Of the 50 patients 35 were females and 15 were males with a mean age of 51.82±16.99 years. One level was treated in 26 patients, 2 levels in 14, 3 levels in 8, and 4 levels were treated in 2 patients. Symptom duration was ranging between 2 and 24 months with a mean of 7.64±5.98 months. Mean preoperative, postoperative, and at the 12th month VAS were 75.2±11.29, 23.8±10.28, and 24.6±11.817, respectively.Forty-eight percent of patients obtained a relative reduction of at least 70% in VAS, and 86% obtained a reduction of at least 60% at the 12th month. Health-related quality of life state was improved in all patients. When the VAS scores were evaluated with respect to the ages of patients, level numbers, and preoperative symptom duration, no significant differences were found, [0.106, 0.635 and 0.526 (preoperative VAS); 0.033, 0.555, and 0.235 (postoperative VAS); 0.701, 0.978, and 0.155 (follow-up VAS), respectively]. CONCLUSIONS: The most important factors determining success of this procedure is strict patient selection criteria and technique of the procedure.

BACKGROUND: Epidural steroid injection (ESIs) is one of the treatment modalities for chronic low back pain (CLBP) with various degrees of success. AIM: We analyzed the efficacy of fluoroscopically guided transforaminal epidural steroid injections (TFESIs) via a preganglionic approach in patients with foraminal stenosis due to lumbar spinal stenosis and lumbar discogenic pain with radiculopathy. MATERIALS AND METHODS: We analyzed the data of 40 patients (February 2008 and April 2009) with the diagnosis of CLBP and treated by fluoroscopically guided TFESIs via a preganglionic approach. Patients were followed-up at one month (short term), six months (midterm) and one year (long term) after injections. Follow-up data collection included the Visual Numeric Pain Scale (VNS) and North American Spine Society (NASS) patient satisfaction scores. RESULTS: The mean age of the patients was 59.87 +/- 15.06 years (range 30 - 89 years, 25 women). Average follow-up period was 9.22 +/- 3.56 months. Statistically significant differences were observed between the pre-procedure and post-procedure VNSs (P < 0.01, Pearson Correlation Test). Improvements in VNS scores were correlated with improvements in the NASS scores. When the VNS scores were evaluated with respect to the age of patient, level numbers, gender, pre-procedure symptom duration and pre-procedure VNS, no significant differences were found (P < 0.05, linear regression test). At short term evaluation in post treatment (one month), 77.78 % of patients were found to have a successful outcome and 22.22 % were deemed failures. Overall patient satisfaction was 67.23 % in the midterm period. Additionally, 54.83 % of patients (N/n: 15/8) had a successful long-term outcome at a follow-up of one year. CONCLUSION: Our data suggest that fluoroscopically guided TFESIs via a preganglionic approach, in patients with foraminal stenosis due to lumbar spinal stenosis and lumbar discogenic pain with radiculopathy, has effective outcome and patients responding to injection have significantly lower post-injection pain scores.

Brucellosis is an infectious disease spread by consumption of non-pasteurized milk products or through contact with infected animals. Spinal involvement is one of the most important complications and the lumbar area is the most frequently affected site. Among the neurological consequences, nerve root compression can be a result of epidural abscess, granuloma or discitis secondary to vertebral body involvement. In this case report we present a 50-year-old male patient with brucellar discitis without spondylitis which caused lumbar disc herniation. We want to emphasize that discitis should also be considered in differential diagnosis of nerve root compression in suspected cases.

BACKGROUND: Traumatic acute subdural hematoma is the most lethal of all head injuries. METHODS: In this study, 113 patients with the diagnosis of posttraumatic acute subdural hematoma, who were operated between 1998 and 2006, were reviewed retrospectively. Statistical analysis was performed to detect any effects of the variables of age, Glasgow Coma Scale (GCS) score on admission, time interval between the trauma and operation, and abnormality in the pupil reaction on the disease mortality and morbidity. RESULTS: Results obtained in the study are discussed and compared with the related current literature. The overall mortality in 113 patients was 56.6%. CONCLUSION: According to the results, the most important determinants of the prognosis are GCS score of the patient on admission, abnormality in pupil reaction, timing of the operation, and the patient's age.

AIM: Coccydynia is a painful condition affecting quality of life. The majority of patients can be successfully treated by non-surgical means. Chemical neurolysis, cryoablation and radiofrequency thermocoagulation (RFT) of ganglion impar are also used in the treatment of visceral pelvic pain. We analyzed the efficacy of RFT of ganglion impar in patients with chronic coccydynia. MATERIAL AND METHODS: We retrospectively analyzed the collected data of 10 patients with chronic coccydynia (pain>6 months) who were treated by RFT of the ganglion. RESULTS: The mean age of the patients was 49.2+/-14.4 (range 27-77) with 8 females (80%) and 2 males (20%). The average follow-up duration was 9.1+/-1.2 months. Statistically significant differences were observed between the preprocedure and post-procedure VNSs (p<0.01). Improvements in VNS scores were correlated with improvements in the EQ-5D scores. Midterm evaluation after the treatment (6 months) revealed that 90% of the patients had a successful outcome and 10% were deemed failures. CONCLUSION: Our data suggest that RFT destruction of ganglion impar in patients with chronic coccydynia has an effective outcome and patients responding to RFT have significantly lower post-RFT pain scores. The most important factors determining success of this procedure is strict patient selection criteria and the technique of the procedure.

OBJECTIVE: The authors present the case of a dumbbell-shaped schwannoma of the upper cervical spine involving the ventral rami of C-2 sensory root and rising through the foramen magnum up to the pontobulbar junction. The 27-year-old male patient complaining of hoarseness, imbalance and experiencing cervical pain and cervical muscle contractions for 2 months was admitted to the hospital. The cervical T1 and T2- weighted magnetic resonance (MR) images revealed the presence of a slightly hyperintense left C1-2 intra-extradural lesion which had eroded the clivus and odontoid process and enlarged the intervertebral foramen and was rising up to ponto-bulbar junction. A posterior approach was used to perform a suboccipital craniectomy and C1- 2 laminectomy, including opening of the dura mater and gross-total removal of the lesion. The cerebrospinal MR image of the patient obtained at the early post-operative period revealed total removal of the lesion. The patient had hypoglossal nerve palsy and mild hemiparesis on the left side which had regressed almost totally at the 3-month follow-up. The far-lateral approach with the patient in the sitting position is very important and facilitates the total removal of the schwannoma. Simple suboccipital craniectomy provided enough exposure for total removal in this case.

AIM: There have been several treatment modalities to reduce the volume of the syringomyelic cavity and the pressure on the brainstem in Chiari Malformation Type I (CM-I). Foramen magnum decompression with and without duroplasty were compared in this retrospective study. MATERIAL AND METHODS: From 2003 to 2006, 27 patients suffering from CMI were operated on at our institute. The following were measured: the ratio of the syringomyelic cavity to the spinal cord; pre-operative tonsillar herniation from the foramen magnum; pre- and postoperative tonsillo-dural distance; and spinoposterior fossa dural angle. RESULTS: 83.3 % of the patients in the non-duroplasty and 73.3% of the patients in the duroplasty group were symptom free. The ratio of syrinx regression was 28+/-10% in the non-duroplasty and 36+/-33% in the duroplasty group. The tonsillodural distance was 3.1+/-1.8 mm in the non-duroplasty and 4.6+/-2.1 mm in the duroplasty group (p>0.05). The spino-posterior fossa dural angle was 133.6+/-9.44 degrees preoperatively and 136.7+/-9.78 degrees postoperatively in the non-duroplasty (p=0.376); 123.7+/-11.7 degrees preoperatively and 129.8+/-11.1 degrees postoperatively in the duroplasty group (p=0.885); no significant difference was found postoperatively (p=0.55, z=1.92), respectively. One patient was re-operated in the non-duroplasty group and thereafter duroplasty was performed. CONCLUSION: Almost the same clinical outcomes can be achieved with and without duroplasty. There might be an option to perform duroplasty if simple procedure fails.

BACKGROUND: Risks related to rebleeding of a ruptured intracranial aneurysm have decreased. However, ischemic neurologic deficits related to vasospasm are still the leading causes of mortality and morbidity. It is well known that vasospasm is a dynamic process affected by various factors. The severity of vasospasm in animal models and clinical observations differ from each other. This variability has not been completely explained by blood and blood degradation products. Therefore, metabolites released from the damaged vessel wall during the bleeding are thought to play an important role in vasospasm. METHOD: To test this hypothesis, we used 46 male Wistar rats that were divided into 7 groups and administered one of the following to cisterna magna: venous blood, arterial blood, arterial wall homogenate, venous wall homogenate, combined mixture of arterial blood and artery wall homogenate, or combined mixture of venous blood and venous wall homogenate. Brainstems of the rats were excised, and the basilar arteries were harvested for morphometric measurements. RESULT: There were significant differences between the degree of vasospasm caused by arterial and venous blood (P < .0001). The intraluminal area of the basilar artery was significantly narrower after application of arterial blood, artery wall homogenate, or their combination (49% +/- 1%) than after venous groups (30% +/- 1.9%) (P < .0001). CONCLUSION: The results of this experiment demonstrated that metabolites from vessel walls play as important roles in the pathophysiology of vasospasm as blood and blood degradation products. Further investigation of these metabolites will improve our understanding of vasospasm, pathophysiology, and its treatment.

Carpal tunnel syndrome (CTS) is an entrapment neuropathy where the median nerve is compressed in the carpal canal. There are many variations of the distal branches of the median nerve at the wrist. Anatomical variations of this nerve have fundamental clinical importance to prevent injuries, especially during limited open or endoscopic surgical procedures. A case is presented of an anomalous course of the recurrent motor branch of the median nerve and high division of the third common digital nerve seen in a limited open carpal tunnel release.

Trigeminal neuralgia (TN) is a common pain syndrome and is characterized by recurrent episodes of intense lancinating pain in one or more divisions of the trigeminal nerve. Neurovascular compression (NVC) has been considered as the main cause of TN in the root entry zone (REZ) of the trigeminal nerve in the cerebellopontine angle cistern. Microvascular decompression (MVD) is the surgical procedure of choice for the treatment of medically refractory TN. MVD has also been shown to provide pain relief even in patients without visible neurovascular compression. Additionally, it has been accepted that MVD can provide the highest rate of long-term patient satisfaction with the lowest rate of pain recurrence. We did, systematic review of the subject and also our own experiences.

AIM: This experimental biomechanical study was performed to determine the effects of multilevel anterior cervical discectomy and excision of posterior longitudinal ligament (PLL) to stabilize the cervical spine using an in vitro animal model. MATERIALS AND METHODS: Fifty fresh cadaveric C3-C6 sheep spine specimens were divided into five experimental groups: Group A was the control group; Group B, one-level discectomy; Group C, two- level discectomy, Group D, three-level discectomy, and Group E, three-level discectomy and excision of PLL, respectively. The specimens were subjected to non-destructive loads cycled from zero to five Newton-meter for flexion, extension, right and left lateral bending, and axial rotation on an electrohydraulic test machine. Load displacement curves were obtained via collected data using strain gauges. The values were obtained for all five groups, statistical differences were determined respectively (P<0.05, ANOVA). RESULTS: One-level discectomy was less stable than the control group, two-level discectomy was less stable than one-level discectomy and three-level discectomy was less stable than two-level discectomy, respectively (P<0.05). Excision of PLL did not seem to affect stability (P>0.05). CONCLUSION: Our data suggested that cervical discectomy decreases stability of sheep spine pieces.

BACKGROUND: The hypoglossal canal (HC) is a region of the skull base whose involvement in many pathological entities is often ignored. Adequate knowledge of the anatomy of the HC and its related bony, neural, and vascular structures is essential for surgery of lesions involving this area. METHODS: Ten adult human cadaver heads from a US source fixed by formalin (20 sides) and 20 dry human skulls from Indian sources (40 sides) were used in this study. Various aspects of the anatomy of this region including the size, course and variation of the hypoglossal nerve and its relationship to the adjacent and canalicular course were recorded. RESULTS: The left HC was located at 10 o'clock and the right HC at the 2 o'clock position with respect to the foramen magnum. The canal was surrounded superiorly by the jugular tubercle, superolaterally by the jugular foramen, laterally by the sigmoid sinus and inferiorly by the occipital condyle. All dry skulls were drilled in the horizontal plane at an axis of about 45 degrees and directed slightly upwards. CONCLUSIONS: Detailed knowledge of the microsurgical anatomy of the region of the HC is crucial when performing surgery for lesions of the condylar region, the lower clivus, and ventral brain stem. This study provides the knowledge required to achieve accurate orientation and effective maneuvers during surgical procedures for treatment of the patient without injuring the vital neural and bony structures.

A 26-year-old female patient under albendazole treatment because of multiple liver and lung hydatid cysts was admitted with headache and convulsions. Bilateral papilloedema and slight right hemiparesis were observed in neurological examination. Neuroradiological evaluation revealed a cystic lesion causing midline shift and oedema in the left frontal lobe. The cyst was removed unruptured using Dowling's technique and postoperative outcome was uneventful. Albendazole therapy was continued due to systemic infection. In her second month of follow-up, she suffered from severe headache and abundant haemoptysis. Control cranial magnetic resonance imaging (MRI) revealed a ring-shaped slightly contrast-enhancing lesion including heterogeneous fibrillary ingredient with surrounding oedema in the left frontal lobe. The further follow-up cranial MRI suggested brain abscess.We present a complicated case of brain hydatid cyst and its management with a successful outcome.

BACKGROUND: The aim of this study was to determine the hospital-based epidemiological data of the head injury patients who admitted to our Emergency Surgery Department. METHODS: The records of the patients (284 males [66%], 146 females [34%]; mean age 30+/-19) with head injury who admitted to our Emergency Surgery Department between 01.01.2006 - 31.12.2006 were analyzed retrospectively. RESULTS: Among the age groups, most head injuries occurred in children (22%) and young adults (30%). The most common trauma types were due to falls (40%) and motor vehicle accidents (37%). The mortality rate in head injury patients was 11%, serious morbidity was 2%, and the rate of deaths from head injury among all deaths in 2006 was 30%. CONCLUSION: According to these data, the most common causes of death in head-injured patients are falls (0-16 years of age) and outside vehicle traffic accidents and cranial gunshot wounds (16-35 years of age), especially for males. Admission Glasgow Coma Score is an important prognostic factor in head-injured patients. Primary precautions for head injury must be taken according to each age group. Further development of the diagnosis and treatment options will help to lower the mortality and morbidity of patients with traumatic brain injury.

BACKGROUND: Colloid cysts are benign intracranial lesions but can show signs of severe obstructive hydrocephalus and present with sudden death. The approaches to colloid cysts have been described by many authors. The treatment modalities can be classified as endoscopic and microsurgical. Bilateral access through the foramen is commonly used with transcallosal surgery to reach the third ventricle but has never been described. Cystic lesions can be excised safely with both approaches but the excision of a solid lesion is still challenging despite advances in microsurgical techniques. METHODS: After routine callosotomy, each foramen of Monroe can be identified with the landmarks of the lateral ventricle. The foramens can be widened with limited manipulation. The solid lesion can be excised with limited traction of the third ventricle and surrounding neural structures. Tumor control can be achieved with the biforaminal approach but the tumor excision should be performed from the right foramen due left side forniceal memory dominance. RESULTS: The postoperative period was uneventful, and the patient was discharged without any memory deficit. CONCLUSION: Manipulation of both fornices increases the risk of significant memory system deficits. Safer and harmless excision can be achieved with the transbiforaminal approach if the tumor excision is performed from the right foramen.

Osteoid osteoma is a benign skeletal neoplasm composed of osteoid and woven bone. The majority of the lesions arise in the cortex of long bones. Osteoid osteoma of the spine is a rare primary spine tumor and those located at the thoracal spine are even rarer. The usual treatment involves complete resection, including the nidus, or alternatively radiofrequency percutaneous ablation is performed. The authors present a 32-year-old female with an unusual localization of the osteoid osteoma in the thoracal spine where imaging modalities were not conclusive for the diagnosis. The T1 vertebra lesion was successfully resected via a posterior approach with T1 laminectomy, including right side C7 and T1 foraminotomies, and vertebroplasty were performed. Histopathology reported the lesion as an osteoid osteoma.

AIM: Previous studies demonstrated that mexiletine has some important features in the prevention of ischemic brain injury such as sodium and calcium canal blockage and free radical occurrence. Our aim was to investigate the effects of mexiletine on ischemic brain injury. MATERIAL AND METHODS: Experiments were performed on 30 adult male Sprague- Dawley rats (285-425 g). Left middle cerebral artery occlusion following microcraniectomy and simultaneous bilateral carotid artery occlusion were performed. Three different treatments were included in this study: (a) "naïve" control group (no drug applied; n = 10); (b) "sham surgery" control group (only saline was applied; n = 10); and a (c) "treatment group (n = 10) where mexiletine was applied. After 24 h from ischemic insult, all rats were decapitated and prepared for immunocytochemical and histopathological analyses. Cerebral infarct volumes were calculated and compared using ANOVA and a Post- Hoc Bonferroni test in each group statistically. RESULTS: The results showed statistically significant differences between the treatment (81.98 +/- 12.58 mm?), control (121.57 +/- 11.41 mm?) and sham (116.08 +/- 12.36 mm?) groups (p < 0,0001), respectively. CONCLUSION: Mexiletine should be considered as an alternative medication for prevention and treatment of ischemic brain injury due to its multipotent effects.

BACKGROUND: This is a report of 5 patients treated surgically for SCMs. METHODS: During the period from 1998 to 2003, 5 patients (4 male and 1 female) harboring SCMs were treated surgically (all of them underwent complete surgical removal). Patients' ages ranged between 22 and 57 years (mean age, 46 years). Median duration of symptoms was 31 months (1-120 months). Diagnosis was made by MRI scan showing lesions in length of 1 to 6 cm in diameter (mean length, 2.9 cm). Three lesions were found in the cervical, one in the upper dorsal, and one in the lower dorsal cord. One of them was located extradurally, one of them intradural extramedullary, and 3 of them intramedullary. RESULTS: An MRI examination showing total removal was performed postoperatively in each patient (the postoperative MRI examinations revealed total removal in all cases). The follow-up period ranged from 1 to 4 years (mean, 27 months). All patients showed clinical improvement, with 3 of them worsening early in the postoperative period but doing better in long-term follow-up (although 3 of 5 patients had worse neurological examinations in the early postoperative period, all recovered in long-term follow-up and clinically improved relative to preoperative status). CONCLUSION: Neurological status of the patients can worsen in the early postoperative period, causing intramedullary operation; but it usually improves relative to preoperative status. Surgical removal seems to be a safe and a promising way of treatment of symptomatic SCMs.
