The ADCON-L $gel^{(R)}$ (Gliatech, Cleveland, OH, USA), a carbohydrate polymer gel. has been shown in a controlled clinical study to inhibit postsurgical adhesions and improve a patient's clinical outcome. Immediate complication of this gel has been reported in the recent literature including back pain, radiculitis and durotomy. However, delayed detection of disturbance of muscle healing and attachment in late postoperative state has been rarely reported. This report documents an unexpected delayed detected complication of the anti-adhesion barrier gel. which was used after lumbar discectomy one year ago, with review of literature.

Intradural lumbar disc herniation[ILDH] is a rare pathology. The pathogenesis of ILDH is not known with certainty. Adhesions between the ventral wall of the dura and the posterior longitudinal ligament[PLL] could act as a preconditioning factor. Diagnosis of ILDH is difficult and seldom suspected preoperatively. Prompt surgery is necessary because the neurologic prognosis appears to be closely related to preoperative duration of neurologic symptoms. Despite preoperatively significant neurological deficits, the prognosis following surgery is relatively good. We report on case of ILDH at L3/4 with differential diagnoses, and the possible pathogenic factors are discussed.

Objective : Discal cyst is rare and causes indistinguishable symptoms from lumbar disc herniation. The clinical manifestations and pathological features of discal cyst have not yet been completely known. Discal cyst has been treated with surgery or with direct intervention such as computed tomography (CT) guided aspiration and steroid injection. The purpose of this study is to evaluate the safety and efficacy of the percutaneous endoscopic surgery for lumbar discal cyst over at least 6 months follow-up. Methods: All 8 cases of discal cyst with radiculopathy were treated by percutaneous endoscopic surgery by transforaminal approach. The involved levels include L5-S1 in 1 patient, L3-4 in 2, and L4-5 in 5. The preoperative magnetic resonance imaging and 3-dimensional CT with discogram images in all cases showed a connection between the cyst and the involved intervertebral disc. Over a 6-months period, self-reported measures were assessed using an outcome questionaire that incorporated total back-related medical resource utilization and improvement of leg pain [visual analogue scale (VAS) and Macnab's criteria]. Results : All 8 patients underwent endoscopic excision of the cyst with additional partial discectomy. Seven patients obtained immediate relief of symptoms after removal of the cyst by endoscopic approach. There were no recurrent lesions during follow-up period. The mean preoperative VAS for leg pain was $8.25{\pm}0.5$. At the last examination followed longer than 6 month, the mean VAS for leg pain was $2.25{\pm}2.21$. According to MacNab' criteria, 4 patients (50%) had excellent results, 3 patients (37.5%) had good results; thus, satisfactory results were achieved in 7 patients (87.5%). However, one case had unsatisfactory result with persistent leg pain and another paresthesia. Conclusion : The radicular symptoms were remarkably improved in most patients immediately after percutaneous endoscopic cystectomy by transforaminal approach.

Objectives : There are many kinds of method to evaluate neural decompression during operation. They are direct visual and manual inspection, intraoperative ultrasound, endoscope, intraoperative computed tomography and intraoperative myelography. We used intraoperative myelography to evaluate the proper decompression of neural elements during the decompressive surgery. Methods : We injected 10-20cc of nonionic water-soluble contrast materials through direct puncture site of exposed dura during operation or lower lumbar level or lumbar drain inserted preoperatively. 12 patients were included in this study. They were 7 patients of centrally herniated lumbar disc disease, 1 patient of multiple lumbar spinal stenosis, 2 patients of thoracic extradural tumor and 2 cervical fracture & dislocations. Results : 5 of 12 patients showed remained neural compression through intraoperative myelography, so they were operated further through other approach. Myelographic dye is heavier than CSF, so the dependent side of subarachnoid space was visualized only. In one case, CSF leakage through hemovac was detected, but it was treated only bed rest for 5 days after hemovac removal. Conclusion :Intraoperative myelography is an effective method to evaluate neural decompression during spinal surgery. This technique is easy and familiar to us, neurosurgeons.

Background: Because of fear of reoperation and low efficiency, some patients with failed back surgery syndrome (FBSS) opt for Korean medicine treatment. Gold standard treatment is not present for FBSS, therefore both surgical and non-surgical treatment are possible. Studies of Korean conservative medicine for FBSS had a short duration of treatment and mainly pre- and post-treatment comparisons. And case of female patients who have worsened after childbirth is rare. The purpose of this study was to report long-term follow-up and rare cases of FBSS. Case summary: A 33-year-old female patient diagnosed with lumbar disc herniation complained with low back pain and radicular pain in the left leg after surgery in 2011. Acupuncture and decoction (Cheongpa-jeon, GCSB-5) were administered to her twice a day for about 6 years and 6 months. The patient's complaints improved with each hospitalization, and Magnetic Resonance Imaging (MRI) showed a slight decrease in the size of the recurrent disc (L4/5) and a newly developed disc (L5/S1) that had deteriorated after delivery. Conclusion: Korean medicine could be used to manage the pain of lumbar spine FBSS patients for 6-7 years and to alleviate lumbago after delivery.

요추 후관절 주위 낭종은 신경근을 누름으로써 요통과 방사통, 신경성 파행을 일으킬 수 있는 드문 질환이다. 34세 남자가 심한 요통 및 우측 하지 방사통을 호소하였다. 자기공명영상에서 척추관 내에서 제3-4번 요추 추간판과 제4번 요추체 후면까지 우측으로 위치한 낭종이 보였다. 영상증폭기 감시하에서 주사 바늘 흡인을 시행하여 1.5 ml의 장액성의 노란 액체가 흡인되었다. 흡인 치료 후, 증상들이 즉각적으로 소실되었다. 자기공명영상 추시 촬영에서 낭종의 재발소견이 보이지 않았다. 저자들이 아는 한 국내에서는 요추 후관절 주위 낭종에 대한 직접적 바늘 흡인 치료에 대한 보고가 전혀 없기에 이 증례를 문헌 고찰과 함께 보고하는 바이다.

Purpose: The purpose of this research was to analyze the results of the combined and posterior approaches for treating thoracolumbar and lumbar burst fractures and to find an adequate method of treatment. Methods: We retrospectively analyzed the cases of 46 patients with unstable thoracolumbar and lumbar burst fractures who had been surgically treated. All cases were divided into two groups based on the operation method used. Eleven patients had undergone the combined approach, while 35 patients had undergone the posterior approach. Radiological and clinical evaluations were performed before surgery, after surgery, and at the final follow-up. Results: The stenotic ratios of the area occupied by the retropulsed bony fragments to the estimated area of the original spinal canal were 68.2% and 45.6% for the combined and the posterior approaches, respectively. No significant differences in the neurological improvement or the corrected state of the sagittal index were noted, but the patients who had been treated with the combined approach group had better results than those who had been treated with the posterior approach group in terms of correction and maintenance of the sagittal index. The average kyphosis corrections at the final follow-up were 15.3 degrees for the patients in the combined approach group and 10.0 degrees for those in the posterior approach group. Surgical time and estimated blood loss were all significantly higher for patients in the combined approach group. Conclusion: The combined and the posterior approaches showed similar results in the improvements of the neurologic state and the corrected state of the sagittal index. However, use of the combined approach is recommended for patients with severe kyphosis and with severe canal encroachment.

This study was conducted to investigate the effect of timing of surgery on outcomes of spine operated patients for lumbar herniated intervertebral disc. The research design was cohort study and based on the data of claims for the medical expenses of health insurance. 21,475 cases who had primary spine surgery between January 1, and December 31, 2003, observed to conservative treatment period in the past two years from preoperative primary diagnosis to timing of primary surgery. According to one and five year follow up monitoring, the probability of occurrence of reoperation was not statistically significant with preoperative duration of symptom. Also one year follow up, the probability of occurrence of complication, was not statistically significant with preoperative duration of symptom. But five year follow up, groups who had one to two month preoperative duration of symptom decreased complication rate than less than a month(95%CI:0.594-0.927). Thus, from the onset of symptoms of back pain before primary surgery with enough and adequate time observation is required. Also, medical consumers or providers to choose surgery in determining prudence is required.

Lateral femoral cutaneous neuropathy occurring during spinal surgery is frequently related to iliac bone graft harvesting, but meralgia paresthetica (MP) can result from the patient being in the prone position. Prone position-related MP is not an uncommon complication after posterior spine surgery but there are only few reports in the literature on this subject. It is usually overlooked because of its mild symptoms and self-limiting course, or patients and physicians may misunderstand the persistence of lower extremity symptoms in the early postoperative period to be a reflection of poor surgical outcome. The authors report a case of prone position-related MP after posterior lumbar interbody fusion at the L3-4 and reviewed the literature with discussion on the incidence, pathogenesis, and possible risk factors related to this entity.
