Objectives : Most cases of cervical ossification of the posterior longitudinal ligament(OPLL) present with myelopathy or myeloradiculopathy, which sometimes is further complicated by minor trauma to the spinal cord. The main purpose of surgery in these patients is the alleviation symptoms but also as protection against further deterioration. The purpose of this study is to analyze the influence of trauma on the surgical outcome in patients with cervical OPLL. Methods : Over the past 13 years, we have operated on 123 patients with myelopathy associated with cevical OPLL. Among these, thirty patients had cervical cord injury associated with major or minor trauma and their clinical and radiographic data were reviewed retrosepctively. Results : As to cause of trauma, seventeen were related with traffic accident and 13 were related with minor slipping injury. The pre- and post-operative motor power were significantly weaker in the patients with trauma, but the degree of motor improvement was significantly higher(trauma group : $0.90{\pm}1.49$, non-trauma group : $0.41{\pm}0.80$). Conclusion : These results indicate that even indirect minor trauma to the cervical spine can cause irreversible changes to the spinal cord if this is associated with underlying cervical stenosis with OPLL. Although less favorable results may be anticipated in patients with trauma, operative decompression could improve motor power and protect further deterioration.

Objective : To evaluate the effectiveness of posterior microforaminotomy in treatment of posterolateral cervical disc herniation, the authors retrospectively analyzed the result of posterior microforaminotomy in our institute. Patients and Methods : Ten patients with radiculopathy due to posterolateral cervical disc herniation have been treated with posterior microforaminotomy from August 1996 to July 2000. We analyzed clinical results in all patients who were followed up for an average of 10 months. Results : The mean age was 47.2 years and all patients were treated with posterior microforaminotomy as primary treatment. one patient was received anterior cervical interbody fusion with iliac bone 12 years before. Clinical improvement in the last follow-up were seen in all patients and there were no complications. Conclusion : Microcervical foraminotomy is considered useful operative method for posterolateral soft disc herniation. We conclude that the posterior microforaminotomy for radiculopathy due to soft posterolateral cervical disc herniation seems to be safe and effective in selective patients.

Objectives : To demonstrate the preventive effect on post-operative spinal deformity of the laminoplasty compared with laminectomy for spinal cord tumor. Methods : Sixteen patients who underwent laminoplasty and 89 patients who underwent lamenectomy were reviewed retrospectively after removal of spinal cord tumors between February 1981 and December 1999. The mean follow-up period after laminoplasty and laminectomy were 29 months(range, 12-49 months) and 66 months(range, 6-120 months) respectively. Patients were observed neurologically and radiologically. Results : Postoperative kyphosis was observed 17 patients(19%) in the laminectomy group, but was not observed in the laminoplasty group. Postoperative slipping was observed 16 patients(18%) in the laminectomy group, but was not observed in the laminoplasty group. Complications such as postoperative scoliosis, rotation, and swan-neck deformity were observed in the laminectomy group, but were not observed in the laminoplasty group. Conclusions : Laminoplasty prevented postoperative spinal deformities after removal of spinal cord tumors, and afforded anatomic reconstruction of the vertebral arch. Additionally, appropriate patient selection maximizes the chance of optimal neurologic outcomes and minimizes complications. Laminoplasty appears to warrant further evaluation as an alternative to wide laminectomies for exposure of intraspinal tumors.

본 논문은 한국 본글로벌 기업의 혁신 과정에서 활용 및 탐색 역량의 선행요인과 결과요인을 다음과 같이 살펴보고자 하였다. 첫째, 활용 및 탐색 역량은 국제기업가지향성(진취성, 위험감수성, 혁신성)에 어떻게 영향을 받는가, 둘째, 활용 및 탐색 역량이 혁신 결과로서 신상품차별화에 어떻게 영향을 미치는가에 대해 알아보고자 하였다. 선행 연구를 바탕으로 본 논문은 192개의 한국 본글로벌 기업 데이터를 수집하여 경로 분석을 하였다. 그 결과, 국제기업가지향성 중 오직 진취성만이 활용 및 탐험 역량에 주요 선행요인으로써 정(+)적 영향을 미친 것으로 나타났다. 활용 역량은 탐험 역량과 부(-)적 연관성을 갖는 것으로 나타났다. 탐험 역량과 신상품차별화의 정(+)적 관련성은 지지되지 못하였으나, 활용 역량은 혁신 결과요인인 신상품차별화에 정(+)적 영향을 미치는 것으로 나타났다. 또한, 연구 결과의 토론, 함의, 제한 및 후속 연구의 방향성에 대해 제시하였다. The study investigated the role of exploitative and explorative capabilities in the innovation process: 1) how exploitative and explorative capabilities are influenced by international entrepreneurial orientation (proactiveness, risk-taking, and innovativeness); and 2) how exploitative and explorative capabilities affect new product differentiation as the outcome of innovation. Building on the previous research, the study tested a research model using path analysis for the data collected from 192 Korean born globals. The results indicated that, among the three international entrepreneurial orientation variables, only proactiviness positively affected exploitative and explorative capabilities as a key antecedent. Exploitative capabilities were found to be negatively associated with explorative capabilities. While the positive relationship between explorative capabilities and new product differentiation was not supported, exploitative capabilities were revealed to positively influence an innovation outcome variable, new product differentiation. Discussion, implications, limitation, and future direction of this study were further suggested

Objective : To evaluate the role of anterior lumbar interbody fusion in treatment of failed back surgery syndrome, the authors retrospectively analyzed the result of anterior lumbar interbody fusion performed in our institute. Methods : Fifteen FBSS patients due to variable causes have been treated with anterior lumbar interbody fusion in our institute from April 1994 to June 1999. We analyzed clinical changes in 15 patients who were followed up for an average of 23 months. Results : The etiologies of FBSS were post operative discitis(6 cases), post operative instability(3 cases), post operative adhesion(5 cases), and recurrence(1 case). These fifteen FBSS patients were treated with anterior lumbar interbody fusion. The overall treatment outcome was satisfactory(excellent and good) in 11 cases. Three patients were slightly improved, but post operative low back pain was remained. One patient who had underwent nerve root injury due to pedicle screw insertion showed no improvement. Conclusion : We conclude that the anterior lumbar interbody fusion for FBSS seems to be safe and favorable treatment in selective patients, because low incidence of nerve injury risk and post-operative infection.

Objective : The authors reviewed 51 patients of spinal cord tumor located at the craniovertebral junction and high cervical area to determine which factors influenced resectability, complications, and postoperative outcomes. Methods : Radiological examinations, clinical data, and operation notes were evaluated, and additional follow-up information was obtained from outpatient examinations. The mean follow-up period was 3.5 years Results : The most common neurological findings were motor deficit(72.5%) and sensory change(47.1%). There was no clinical finding that is considered as pathognomic. Meningioma(18 cases, 35.3%) was the most common tumor in this region. Total removal was achieved in 45 patients. There was no surgical mortality. Immediate postoperative motor weakness were encounted in 11 cases(21.6%) which improved in long term followup except two patients. Conclusions : The location and relationship of the tumor to surrounding struncture determine its resectability. Postoperative results were related to the preoperative neurological status and pathological findings.

Objective : The introduction of MRI makes it easy to detect multiple lumbar disc herniation. However, MRI is not a physiologic test for detecting the symptomatic level. For the surgical plan, it is very important to determine the symtomatic level among the multiple lumbar disc herniation. In this regard, we studied diagnostic significance of discography on multiple lumbar disc herniation in determining the symptomatic level. Method and Material : We retrospectvely analyzed the discographic and clinical findings of 121 patients with multiple lumbar disc herniation for investigating the diagnostic availability of discography. All were surgically treated from January 1995 through May 1998. Result : Discography provocated the same pain as usual symptom in 99 out of 121 patients(81.8%). Compared with surgical findings, the diagnostic accuracy of the discography in multiple lumbar disc herniation was 75.6%, sensitivity was 64.6%, and specificity 87.2%. There was no correlation between the pain provocation of discography and the extent of annular degeneration on CT/discogram. The pain provocation showed good correlation with the extent of annular disruption on CT/discogram. The rate of same result(correlation rate) between the discography and D.I.T.I was 81.4% in multiple lumbar disc herniation patients with unilateral leg pain. Conclusion : These results indicate that in multiple lumbar disc herniation, the discography is considered useful diagnostic tool to determine the symptomatic level and to decide the surgical plan.
