Although anterior cervical plates are thought to be good tools, their clinical results have not been compared with those of anterior cervical fusion without a plating system in the domestic scientific literature. As there are some advantages as well as shortcomings in these two surgical methods, it is imperative to know which one might be better in terms of the postoperative complications and management. Therefore, the authors reviewed 80patients undergoing anterior cervical fusion during the period of January 1992 to May 1994. Top plate placement was made in 25 and simple fusion without a plating system was applied in 55. The average follow-up period was 9.6 months. In the patients undergoing simple cervical fusion, thirty-two patients(58%) needed rigid braces such as halo braces and Minerva casts for 3 months postoperatively. Thirteen patients(24%) showed graft complications including graft extrusion, whereas patients undergoing plate placement needed only semi-rigid Philadelphia braces for 4 to 8 weeks pos toperatively. Two patients(8%) showed graft setting and screw breakage without any indication of reoperation. However there appeared no difference in the immediate postoperative course of clinical symptoms and the fusion rate(95 vs 96%) at the final follow-up day between the simple fusion and the plate placement patients. The authors conclude that a plating system in anterior cervical fusion may be safe in spite of more extensive operations, and is more likely to offer postoperative stability in the cervical spine and early ambulation and rehabiliation without rigid braces.

PURPOSE: Serum levels of G-CSF and GM-CSF were measured and CFU-GM assay using G- CSF, GM-CSF and SCF was conducted to evaluate the influence of hematopoietic growth factor on the precursor cells of cyclic neutropenia. METHODS: A 7-year-old male with cyclic neutropenia was studied. Marrow mononuclear cells were isolated at neutrophil nadir and recovery and cultured in methylcellulose media with or without G-CSF, GM- CSF and SCF. CD34 positive cells were evaluated using flow cytometry. Serum levels of G-CSF and GM-CSF were measured by ELISA. RESULTS: The Numbers of CFU-GM without growth factors were 50 at neutrophil nadir and 33 at the recovery phase in the patient and show increased colony forming capacity. CD34 positive cells were 9.32% at nadir and 14.17% at recovery. Increasement of CFU-GM with G-CSF at nadir and recovery were 46% and 118% and those with GM-CSF were 70% and 78% respectively, compared with 54.4% and 78.2% in control groups. In contrast, the presence of SCF did not enhance CFU-GM number in the patient, but in the control group, increasement with SCF was 28.9 %. There an was inverse relationship between serum G-CSF levels and peripheral neutrophil count whereas those of GM-CSF were constant. CONCLUSION: Serum G-CSF level showed inverse relationship with neutrophil counts. The response of progenitor cells to G-CSF and GM-CSF was not impaired. The presence of SCF did not enhance CFU-GM number in the patient. This result suggests that the abnormality in hematopoiesis in cyclic neutropenia may involve more immature progenitor cells responsive to SCF.

The finding of a traumatic subdural hygroma(SDHy) raises the question of whether to remove it surgically or not, because the management is still controversial. There has been noting but CT scan and clinical findings for neurosurgeons to decide surgical management, and most of neurosurgeons are still dependent upon their own experiences to decide the way of management for SDHy. In the present study, the authors investigated the changes of cerebral blood flow in 10 patients with SDHy by SPECT, and their relationships with the clinical findings and the results of 6-months postinjury. This study indicates that hypoperfusion of the frontal cortex, examined within a week postinjury, is a good indication for surgical management, and improvement of hypoperfusion at the follow-up SPECT, 1 month later, can predict better prognosis particularly in the cases of young age without associated brain injuries.

14 supratentorial and 6 infratentorial arachnoid cysts, diagnosed and treated at Kangnam St Mary's Hospital from 1983 to 1988, are reported. The most common presenting symptoms in children were craniomegaly, delayed development, increased ICP and neurological focal signs. Neuroradiological examination included plain skull X-ray, brain CT and metrizamide CT or isotope study. Therapeutic criteria according to the clinical and radiological findings were reviewed. The results were as follows; 1) The patient below age of 2 yrs who's brain had a potent ability of growth should be operated in any cases for reducing mass effect. 2) In sylvian lesion, Type II and III according to the classification of Galassi were well treated with C-P snunt. 3) In infratentorial lesion, all patients had hydrocephalus and the patient who had communicated with subarachnoid space in metrizamide CT were well treated with V-P shunt and who not communicated with subarachnoid space was well treated with Y-shunt. 4) We had good results by fenestration above the age of 3 yrs and by C-P shunt under the age of 2 yrs in supratentorial lesion.

The average interval from first operation to recurrence is about 4 years and the reported shortest interval of malignant meningioma is about 6 months. The authors reported a case of rapidly regrowing benign meningioma, located on the outer 1/3 of the right sphenoid wing. The patient was free of recurrence only at 4 months after the first surgery in spite of macroscopic complete removal of the tumor. Factors associated with recurrence of meningioma are also discussed.

OBJECTIVE: To investigate the sagittal sacropelvic morphology and balance of the patients with SIJ pain following lumbar fusion. METHODS: Among 452 patients who underwent posterior lumbar interbody fusion between June 2009 and January 2013, patients with postoperative SIJ pain, being responded to SIJ block were enrolled. For a control group, patients matched for sex, age group, the number of fused level and fusion to sacrum were randomly selected. Patients were assessed radiologic parameters including lumbar lordosis, pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS). To evaluate the sagittal sacropelvic morphology and balance, the ratio of PT/PI, SS/PI and PT/SS were analyzed. RESULTS: A total of 28 patients with SIJ pain and 56 patients without SIJ pain were assessed. Postoperatively, SIJ pain group showed significantly greater PT (p=0.02) than non-SIJ pain group. Postoperatively, PT/PI and SS/PI in SIJ pain group was significantly greater and smaller than those in non-SIJ pain group respectively (p=0.03, 0.02, respectively) except for PT/SS (p=0.05). SIJ pain group did not show significant postoperative changes of PT/PI and SS/PI (p=0.09 and 0.08, respectively) while non-SIJ pain group showed significantly decrease of PT/PI (p=0.00) and increase of SS/PI (p=0.00). CONCLUSION: This study presents different sagittal sacropelvic morphology and balance between the patients with/without SIJ pain following lumbar fusion surgery. The patients with SIJ pain showed retroversed pelvis and vertical sacrum while the patients without SIJ pain have similar morphologic features with asymptomatic populations in the literature.

It is well documented that dorsal root entry zone(DREZ) lesions were good method to control intractable chronic deafferentation pain of spinal origin which was not controlled with various medical and surgical treatment. Experience with radiofrequency lesions of dorsal root entry zone in 3 of patients with post herpetic pain and 1 of patient with post amputation pain are reported. The follow-up period ranging from 3-20 months and all patients obtained satisfactory pain relief.
