Transforaminal lumbar interbody fusion (TLIF) is commonly used procedure for spinal fusion. However, there are no reports describing anterior cage dislodgement after surgery. This report is a rare case of anterior dislodgement of fusion cage after TLIF for the treatment of isthmic spondylolisthesis with lumbosacral transitional vertebra (LSTV). A 51-year-old man underwent TLIF at L4-5 with posterior instrumentation for the treatment of grade 1 isthmic spondylolisthesis with LSTV. At 7 weeks postoperatively, imaging studies demonstrated that banana-shaped cage migrated anteriorly and anterolisthesis recurred at the index level with pseudoarthrosis. The cage was removed and exchanged by new cage through anterior approach, and screws were replaced with larger size ones and cement augmentation was added. At postoperative 2 days of revision surgery, computed tomography (CT) showed fracture on lateral pedicle and body wall of L5 vertebra. He underwent surgery again for paraspinal decompression at L4-5 and extension of instrumentation to S1 vertebra. His back and leg pains improved significantly after final revision surgery and symptom relief was maintained during follow-up period. At 6 months follow-up, CT images showed solid fusion at L4-5 level. Careful cage selection for TLIF must be done for treatment of spondylolisthesis accompanied with deformed LSTV, especially when reduction will be attempted. Banana-shaped cage should be positioned anteriorly, but anterior dislodgement of cage and reduction failure may occur in case of a highly unstable spine. Revision surgery for the treatment of an anteriorly dislodged cage may be effectively performed using an anterior approach.

Objective : Posterior lumbar interbody fusion(PLIF) provides the favorable outcome to degenerative lumbar disease, especially isthmic spondylolisthesis. To determine the long-term effect of PLIF using psterior movable segment, we analysed the results of follow-up radiologic changes and surgical outcome retrospectively Patients and Method : During the past 11 years(1989. 1.-1999. 9.), 148 patients with symptomatic lumbar spondylolisthesis were managed at our department and the clinical wants were throughly recieved and final outcome is determined at last follow up. PLIF using antogenous bone(posterior movable segment, iliac bone and rib) were performed in 106 case. Results : After an average follow-up period of 33 months(range ; 15-58 months), the results were excellent in 66 cases, good in 37 cases, fair in 2 cases and poor in 1 cases. And the satisfactory results were 103 cases(98.2%) in PLIF,. Conclusion : In conclusion, patients who underwent PLIF with autologous bone graft had good clinical and radiological outcomes without significant neurological complications.

Objective : To evaluate clinical and radiological results of two different fusion techniques in adult low-grade isthmic spondylolisthesis. Methods : Between November 2003 and December 2004, 46 consecutive patients underwent instrumented mini-transforaminal lumbar interbody fusion (mini-TLIF) (group I) at Wooridul Spine Hospital, Seoul, Korea. Between February 2003 and October 2006, 32 consecutive patients underwent instrumented circumferential fusion (group II) at Leon Wiltse Memorial Hospital, Suwon, Korea. The mean follow-up periods were 29.7 and 26.1 months, respectively. Results : Mean visual analog scale (VAS) scores for back and leg pain decreased, respectively, from 6.98 and 6.33 to 2.3 and 2.2 in group I and from 7.38 and 6.00 to 1.7 and 1.0 in group II. Mean Oswestry disability index (ODI) improved from 51.85% to 14.4% in group I and from 60% to 9.1% in group II. In both groups, VAS and ODI scores significantly changed from pre- to postoperatively (p<0.001), but postoperative outcome between groups was statistically not significant. Radiologic evidence of fusion was noted in 95.7% and 100% of the patients in group I and II, respectively. In both groups, changes in disc height, segmental lordosis, degree of listhesis, and whole lumbar lordosis between the pre- and postoperative periods were significant except whole lumbar lordosis in both groups. Conclusion : Clinical and functional outcomes demonstrate no significant differences between groups in treating back and leg pain of adult patients with low-grade isthmic spondylolisthesis. However, in terms of operative data (i.e. operation time and hospital stay), instrumented mini-TLIF demonstrated better results.

Objectives : The goal of operation for degenerative lumbar diseases is to relieve radiculopathy and low back pain and to prevent further degeneration. The authors analyzed the surgical results of posterior lumbar interbody fusion(PLIF) and $0^{\circ}$ fixation to evaluate the proper treatment policy in spinal stenosis, degenerative spondylolisthesis and low grade isthmic spondylolisthesis. Material and Methods : The authors performed PLIF on 92 patients and $0^{\circ}$ fixation on 138 patients with spinal stenosis, degenerative spondylolisthesis and low grade isthmic spondylolisthesis. We retrospectively studied clinical outcomes and subjective satisfaction of these patients by several criteria such as visual analog scale(VAS), Prolo's economic and functional outcome scale, medication usage after operation and questionaire for overall outcome. Result : Pre- and postoperative VAS on back pain and leg pain showed decrease of pain from 6.5, 6.7 to 2.2, 2.4 in PLIF group and from 7.0, 7.2 to 2.5, 2.7 in $0^{\circ}$ fixation group. Excellent and good outcomes on Prolo's scale were 81.5% in PLIF group and 82.6% in $0^{\circ}$ fixation group. Medication usage after operation was reduced in 79.3% of PLIF group and in 78.3% of $0^{\circ}$ fixation group. Patients' self-reported overall success of their procedure showed 82% in PLIF group and 84% in $0^{\circ}$ fixation group. Conclusion : Both PLIF and $0^{\circ}$ fixation showed good outcomes and provided biomechanically stable fusion in spinal stenosis, degenerative spondylolisthesis and low grade isthmic spondylolisthesis. Therefore, only PLIF seems necessary and considered a proper surgical treatment for these disorders.

Background: Recently, there have been several case reports and retrospective studies about the incidence of intradiscal (ID) injection during transforaminal epidural steroid injection (TFESI). Inadvertent ID injection is not a rare complication, and it carries the risk of developing diskitis, although there has been no report of diskitis after TFESI. We prospectively evaluated the incidence of inadvertent ID injection during lumbar TFESI and analyzed the contributing factors. Methods: Ten patients received 2-level TFESI, and the remaining 229 patients received 1-level TFESI. When successful TFESI was performed, 2 ml of contrast dye was injected under real-time fluoroscopy to check for any inadvertent ID spread. A musculoskeletal radiologist analyzed all magnetic resonance images (MRIs) of patients who demonstrated inadvertent ID injection. When reviewing MRIs, the intervertebral foramen level where ID injection occurred was carefully examined, and any anatomical structure which narrowing the foramen was identified. Results: Among the 249 TFESI, we identified 6 ID injections; thus, there was an incidence of 2.4%. Four patients had isthmic spondylolisthesis, and the level of spondylolisthesis coincided with the level of ID injection. We further examined the right or left foramen of the spondylolisthesis level and identified the upward migrated disc material that was narrowing the foramen. Conclusions: Inadvertent ID injection during TFESI is not infrequent, and pain physicians must pay close attention to the type and location of disc herniation.

Abducens nerve palsy associated with spinal surgery is extremely rare. We report an extremely rare case of abducens nerve palsy after lumbar spinal fusion surgery with inadvertent dural tearing, which resolved spontaneously and completely. A 61-year-old previous healthy man presented with chronic lower back pain of 6 weeks duration and 2 weeks history of bilateral leg pain. He was diagnosed as having isthmic spondylolisthesis at L4-5 and L5-S1, and posterior lumbar interbody fusion was conducted on L4-5 and L5-S1. During the operation, inadvertent dural tearing occurred, which was repaired with a watertight dural closure. The patient recovered uneventfully from general anesthesia and his visual analogue pain scores decreased from 9 pre-op to 3 immediately after his operation. However, on day 2 he developed headache and nausea, which were severe when he was upright, but alleviated when supine. This led us to consider the possibility of cerebrospinal fluid leakage, and thus, he was restricted to bed. After an interval of bed rest, the severe headache disappeared, but four days after surgery he experienced diplopia during right gaze, which was caused by right-side palsy of the abducens nerve. Under conservative treatment, the diplopia gradually disappeared and was completely resolved at 5 weeks post-op.

목적 소아에서 우연히 발견되는 요추 척추분리증의 유병률을 평가하고자 한다. 대상과 방법 2014년 3월부터 2018년 12월까지 복부-골반 컴퓨터단층촬영술을 시행한 11세 미만의 환자 809명(평균나이 7.0 ± 2.7세, 남아:여아 = 479:330)의 자료를 후향적으로 분석하였다. 척추분리증의 유무, 척추분리증이 있는 위치, 그리고 편측성(일측성 혹은 양측성)을 기록하였다. 척추분리증의 유무에 따라 환자군 spondylolysis (이하 SP) 그룹과 non-SP 그룹으로 나누었다. 결과 20명의 환자에서 21개의 척추분리증이 확인되었다(20/809, 2.5%). SP 그룹의 평균 나이가 non-SP 그룹보다 많았다(7.8 ± 1.8세 vs. 6.9 ± 2.7세, p > 0.05). 남아에서 여아보다 유병률이 높았다(15/479 [3.1%] vs. 5/330 [1.5%], p > 0.05). 만 6-10세의 학령기 연령에서 만 0-5세의 미취학 연령보다 유병률이 높았다(17/538 [3.2%] vs. 3/271 [1.1%], p > 0.05). 척추분리증은 요추 5번에서 가장 흔하게 보였고(76.2%), 8세 남아에서 두 개의 요추에서 척추분리증을 보였다. 10세 남아에게서 척추분리전방전위증이 확인되었다(1/809, 0.1%). 11건의 일측성 척추분리증은 확인되었다(11/21, 52.4%). 결론 본 연구에서 11세 미만의 환자에서 척추분리증의 유병률은 2.5%였다. 척추분리증은 여아보다는 남아에게서, 미취학 연령군보다는 학령기 연령군에서 더 높은 유병률을 보였으나, 통계학적으로 유의미한 차이는 없었다.
