Objectives : The purpose of this study was to evaluate surgical outcomes and complications of spinal deformity associated with neurofibromatosis type-1 (NF-1). Methods : From 2012 to 2018, patients suffering from spinal deformity associated with NF-1 who underwent surgical correction were identified. Demographic data and radiographic measures were retrospectively reviewed. Pre- and postoperative whole spine radiograph images were used to determine both coronal and sagittal Cobb angles. All of patients underwent 3-dimentional computed tomographic scan and magnetic resonance imaging scan to confirm dystrophic features. For evaluation of clinical outcomes, we surveyed the pre- and postoperative scoliosis research society-22r (SRS-22r) score. Results : Seven patients with spinal deformity associated with NF-1 were enrolled in this study. The mean age of patients was 29.5±1.2 years old. The mean follow-up period was 2.8±1.4 years. The apex of the deformity was located in cervicothoracic (n=1), thoracic (n=4), and lumbar region (n=2). Most patients have poor bone quality and decreased bone mineral density with average T-score of -3.5±1.0. All patients underwent surgical correction via posterior approach. The pre- and postoperative mean coronal and sagittal Cobb angle was 61.6±22.6° and 34.6±38.1°, 56.8±18.5° and 40.2±9.1°, respectively. Mean correction rate of coronal and sagittal angle was 44.7% and 23.1%. Ultimate follow-up SRS-22r score (average score, 3.9±0.4) improved comparing to preoperative score (average score, 3.3±0.9). Only one patient received revision surgery due to rod fracture. No serious complication occurred, such as neurological deficit, and viscerovascular injury. Conclusion : The surgical correction of patients having spinal deformity associated with NF-1 is challenging, however the radiographic and clinical outcomes are satisfactory. The all posterior approach can be a safe and effective surgical option for patients having dystrophic curves associated with NF-1.

Purpose: Rollover motor vehicle crashes have a higher injury severity and fatality than other motor vehicle crash types. From a left-quarter turn rollover accident of 25-passenger bus, we intend to assess the injury of the occupant and the injury severities according to the occupants' position. Methods: We carried out the 3 steps investigation of occupants' interview, visiting the repair shop and using the police report. We analyzed injuries sustained by occupants, and compared injury severities considering column, row in occupant's position and passenger interaction Results: The rollover involved 14 passengers in the bus who were all old women except a man driver. The most common injury was in the upper extremity, with six occurrences being a left clavicle fracture. Major injuries including hemothorax and pneumothorax were diagnosed at left side of the occupant. In the comparison of injury severity among driver's column (left side), mid column and passengercolumn, ISS of passenger column was the highest ($9.9{\pm}7.4$, $8.8{\pm}5.5$, and $10.3{\pm}4.0$, respectively, p>0.05). The injury severity of multiple occupants by row was higher than that of single occupant (10.8 vs. 3, p<0.05). Conclusion: An occupant must fasten their seat belt to prevent an injury by passenger interaction in the left-quarter turn rollover accident of a bus.

목적 : 전이성 척추 종양은 가장 흔한 전이성 종양 중의 하나로 치료에 있어 보통 보존적 요법이 선호되어 왔으나 신경학적 증상과 삶의 질의 개선이 극히 불량하였다. 수술적 치료 후에 신경학적 증상의 변화와 임상증상의 개선정도, 생존 기간의 증가 등에 대해 평가하였다. 대상 및 방법 : 1991년 8월부터 1999년 6월까지 본원에서 경험하였던 전이성 척추 종양 중 수술적 치료 후 추시관찰이 가능하였던 14례를 대상으로 하여 의무기록과 방사선학적 검사 등을 후향적으로 검토하여 연령별, 성별, 해부학적 발생 부위별 분포와 각각의 원발 종양에 따른 골 전이의 양상에 대해 조사하였고, 방사선 치료로 도움이 안될 때, 신경학적 증상이 악화될 때, 척추 불안정성이 있을 때, 원발 종양을 알지 못할 때, 병적 골절이 있을 때, 기대여명이 6주 이상일 때, 만성적인 통증이 있을 때 시행하였던 수술적 치료 전후의 증상의 개선 정도를 평가하여 문헌 고찰과 함께 분석하였다. 결과 : 전이성 척추 종양은 여자에서 더 많이 발생하였고 30대에서 70대까지 연령이 다양하였으며 원발 종양으로 여자는 유방암, 남자는 폐암이 가장 많았고 가장 흔한 전이 부위는 흉추부였다. 수술 전 마비의 정도가 수술 후 임상 증상의 호전에 영향을 미친 것으로 나타났으며 수술 후 전이성 척추 종양의 평균 여명은 사망한 11례에서 8.9개월, 살아있는 3례에서 14.7개월이었다. 결론 : 전이성 종양에 대한 수술적 치료는 전이성 척수 종양이 의심될 때, 치료와 동시에 조기 진단이 가능하며 그 방법과 관계없이 동통과 신경학적 증상의 회복에 큰 도움을 줄 수 있고, 초기의 적극적 치료로 삶의 질과 생존 기간을 향상시킬 수 있다. 추후 원발 종양의 종류에 따른 전이성 척수 종양의 분류와 이에 따른 수술적 치료의 역할에 대한 평가가 더 필요하리라 사료된다.
