Objective : The purpose of the present study was to examine neurologic changes, fusion rate and degree of kyphosis from the surgical results of those patients who underwent multi-level anterior interbody fusion and internal fixation. Methods : Among 63 cases of the patients who received multi-level anterior interbody fusion and internal fixation in 5 years between 1995 to 1999 at the neurosurgery department, we performed a retrospective study in 52 cases that could be followed up with dynamic view imaging ; the results were compared and analyzed. The analysis was based on the results of history taking, physical findings and radiologic findings, and Odom criteria were used to classify those cases with neurologic changes. Results : Among those 52 cases in whom the follow-up was possible for at least a year and dynamic view imaging was possible, bone fusion was seen in 93% of the trauma cases and 95% in the non-trauma cases and overall bone fusion was observed in 94% of the cases. Bone fusion was seen in 93% of the autobone cases, 95% of the allobone cases, and 94% of the Mesh cases. Radiologic changes were observed by comparing the lateral view after surgery ; kyphosis was seen in 53% of the autobone cases, in 70% of the allobone cases, and in 35% of Mesh cases ; in 45% and 60% of the non-trauma cases and trauma cases, respectively ; and in 55% of the 2 level fusion cases and 46% of the 3 level fusion cases. Neurologic changes classified according to Odom criteria showed excellent result in 48% of all the cases, good in 23%, fair in 4%, and poor in 25%. Conclusion : Even those cases with multi-level fusion, a high fusion rate could be obtained by performing anterior interbody fusion and internal fixation ; those cases with kyphosis were related more with the presence or absence of posterior compartment injury rather than the fusion level ; and those trauma cases showed not much difference in the fusion rate compared with non-trauma cases but had a high possibility of kyphosis.

본 연구는 자가간호프로그램이 요추간판제거술 환자의 운동이행 자기효능감, 자가간호지식, 자가간호이행에 미치는 효과를 확인하기 위한 실험연구이다. 대상자는 D광역시 소재 일개 척추전문병원 입원환자 중 미세현미경 요추간판제거술을 받은 환자로 실험군 26명, 대조군 27명이다. 수집된 자료는 SPSS 25프로그램을 이용하여 평균, 백분율, 표준편차, t-test, χ²-test, t-test, repeated measures ANOVA로 분석하였다. 연구결과 자가간호프로그램 중재를 받은 실험군은 제공받지 않은 대조군에 비해 시간이 경과함에 따라 보조기 관리지식(p=.001)과 일상생활관리지식점수(p=.005)가 더 높아 지지되었다. 또한 자가간호프로그램을 제공받은 실험군은 제공받지 않는 대조군보다 보조기 관리이행도(p=.011), 일상생활 이행도(p=.007), 유해생활 습관관리 이행도(p=.011)가 높아 지지되었다. 따라서 자가간호프로그램은 요추간판제거술 환자의 수술 전후 적용을 통해 운동이행 자기효능감, 자가간호지식 및 자가간호이행도를 향상시켜 보다 빠른 회복을 도울 수 있는 프로그램이라고 할 수 있다.

요추에 퇴행이 발생하였을 때 이를 치료하기 위해 요추 유합술이 시행된다. 유합술은 척추체 사이의 추간판을 제거하고 뼈 그래프트 등을 삽입하여 굳혀 하나 이상의 분절을 완전히 고정시켜 척추의 안정성을 복원한다. 둘 이상의 척추체가 단단히 유합될 수 있게끔 척추체를 고정하는 수단으로 척추경 나사못과 연결봉이 환자의 체내에 삽입된다. 본 연구에서는 중증 요추 퇴행성 질환의 치료에 쓰이는 척추 유합술에서 사용하는 척추경 나사못 구조물이 적용된 총 7개의 환자 맞춤형 요추 유한 요소 모델을 생성하였다. 생성한 모델에 각각 티타늄과 CFR-PEEK로 구성된 연결봉을 구성하였다. 척추의 4가지 대표적 거동에 대해 유한요소해석과 통계적 분석을 진행하여 연결봉의 재질이 척추 상태에 미치는 의공학적 영향을 조사하였다. 인접 분절의 추간판 내 압력과 각 분절의 관절 구동 범위가 의공학적 영향을 확인하기 위한 지표로 사용되었다. 연결봉에 CFR-PEEK를 사용한 경우 Ti 연결봉에 비해 인접 분절의 추간판 내 압력은 감소하였고 각 분절의 관절 구동 범위는 증가하였다. 그러나 모든 하중조건에서 통계학적으로 유의미한 경향성 차이는 관찰되지 않았다.

Objective : To evaluate the surgical outcomes of partial pedicle subtraction osteotomy (PPSO) in patients with thoracolumbar fractures and compare the outcomes of PPSO for burst fractures with those for posttraumatic kyphosis (PTK). Methods : From June 2013 to May 2019, 20 consecutive adult patients underwent PPSO for thoracolumbar fractures at the levels of T10 to L2. Of these patients, 10 underwent surgery for acute fractures (burst fractures), and 10 for sequelae of thoracolumbar fractures (PTK). Outcomes of PPSO were evaluated and compared between the groups. Results : Twenty patients (each 10 patients of burst fractures and PTK) with a mean age of 64.7±11.1 years were included. The mean follow-up period was 21.8±11.0 months. The mean correction of the thoracolumbar angle was -34.9°±18.1° (from 37.8°±20.5°preoperatively to 2.8°±15.2° postoperatively). The mean angular correction at the PPSO site was -38.4°±13.6° (from 35.5°±13.6° preoperatively to -2.9°±14.1° postoperatively). The mean preoperative sagittal vertical axis was 93.5±6.7 cm, which was improved to 37.6±35.0 cm postoperatively. The mean preoperative kyphotic angle at the PPSO site was significant greater in patients with PTK (44.8°±7.2°) than in patients with burst fractures (26.2°±12.2°, p=0.00). However, the mean postoperative PPSO angle did not differ between the two groups (-5.9°±15.7° in patients with burst fractures and 0.2°±12.4° in those with PTK, p=0.28). The mean angular correction at the PPSO site was significantly greater in patients with PTK (-44.6°±10.7°) than in those with burst fractures (-32.1°±13.7°, p=0.04). The mean operation time was 188.1±37.6 minutes, and the mean amount of surgical bleeding was 1030.0±533.2 mL. There were seven cases of perioperative complications occurred in five patients (25%), including one case (5%) of neurological deficit. The operation time, surgical bleeding, and complication rates did not differ between groups. Conclusion : In cases of burst fracture, PPSO provided enough spinal cord decompression without corpectomy and produced sagittal correction superior to that achieved with corpectomy. In case of PTK, PPSO achieved satisfactory curve correction comparable to that achieved with conventional PSO, with less surgical time, less blood loss, and lower complication rates. PPSO could be a viable surgical option for both burst fractures and PTK.

Objectives The purpose of this study was to compare the effects between the degree of herniated intervertebral lumbar disc (HIVD) at L4-5 level and improvement of low back pain treated by Korean Medicine therapy. Methods 567 patients who received inpatient treatment from May 2014 to December 2015 in the Daejeon-Jaseng of Korean Medicine Hospital were divided into 6 groups by the degree of HIVD at L4-5 level confirmed with a Lumbar spine magnetic resonance imaging. All patients received a combination of treatment including acupunture, chuna manual therapy, pharmacopunture, herbal medication. They were compared and analyzed on the basis of improvement between measuring Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), EuroQol-5 Dimension Index (EQ5D Index) as they were hospitalized and as they were discharged. The statistically significance was evaluated by SPSS 23.0 for windows. Results After treatment, Normal stage on Intervertebral Lumbar Disc at L4-5 level group's Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), EuroQol-5 Dimension Index (EQ5D Index) improvement was $1.30{\pm}1.62$, $4.52{\pm}11.82$ and $0.04{\pm}0.11$ respectively. Bulging group's improvement was $3.25{\pm}2.81$, $8.28{\pm}13.02$ and $0.09{\pm}0.17$ respectively. Spinal canal occupying ratio (SOR) less than 20 group's improvement was $2.15{\pm}1.92$, $11.79{\pm}17.81$ and $0.13{\pm}0.23$ respectively. SOR 20 to less than 40 stage group's improvement was $2.13{\pm}1.92$. $10.79{\pm}15.93$ and $0.10{\pm}0.26$ respectively. SOR 40 to less than 60 group's improvement was $2.16{\pm}2.24$, $9.80{\pm}16.62$ and $0.15{\pm}0.25$ respectively. Surgery group's improvement was $2.47{\pm}2.21$, $11.64{\pm}18.53$ and $0.15{\pm}0.27$ respectively (p<0.03). But there was no statistically significance between 6 group's improvement after treatment (p>0.05). Conclusions After inpatient treatment by Korean Medicine therapy, Most patient's pain, disability and Health Related Quality of Life was improved significantly. But there was no statistically correlation between the degree of HIVD at L4-5 level and improvement of low back pain. So We think that future research of higher quality and correct statistics shall be necessary.
