Objective : So called "minimally invasive procedures" have evolved from chemonucleolysis, automated percutaneous discectomy, arthroscopic microdiscectomy that are mainly working within the confines of intradiscal space to transforaminal endoscopic technique to remove herniated epidural disc materials directly. The purpose of this study is to assess the result of endoscopic spinal surgery and favorable indication in the thoracolumbar spine. Methods : The records of 71 patients, 73 endoscopic procedures, were retrospectively analysed. Yeung Endoscopic Spine Surgery system with 7 mm working sleeve and $25^{\circ}$ viewing angle was used. The mean follow up period was 6 months [range, 3-9]. Results : Operated levels were from T12-L1 disc down to L5-L6 of S1 disc. Of 71 cases, 2 patients underwent transforaminal endoscopic surgery twice due to recurrence after initial operation. MacNab's criteria was used to assess the outcome. Favorable outcome, excellent of good, was seen in 78% [57 procedures] of the patients. Among 11 fair outcomes, only 1 procedure was followed by secondary open procedure, laminectomy with discectomy. Two of 5 poor outcomes were operated again by same procedure which resulted in fair outcomes. One patient with aggravated cauda equina syndrome remained poor and a lumbar fusion procedure was performed in other patient with poor outcome. There were 2 postoperative discitis that were treated with conservative care in one and anterior lumbar interbody fusion in the other. Conclusion : Evolving technology of mechanical, visual instrument enables minimal invasive procedure possible and effective. The transforaminal endoscopic spinal surgery can reach as high as T12-L1 disc level. The rate of favorable outcome is mid-range among reported endoscopic lumbar surgery series. Authors believe that the outcome will be better as cases accumulate and will be able to reach the fate of standard open microsurgery.
Objective : In Korea, early vertebroplasty (EVP) or delayed vertebroplasty (DVP, which is performed at least 2 weeks after diagnosis) were performed for the treatment of acute osteoporotic compression fracture (OCF) of the spine. The present study compared the outcomes of two surgical strategies for the treatment of single-level acute OCF in the thoracolumbar junction (T12-L2). Methods : From 2004 to 2010, 23 patients were allocated to the EVP group (EVPG) and 27 patients to the DVP group (DVPG). Overall mean age was $68.3{\pm}7.9$ and minimum follow-up period was 1.0 year. Retrospective study of clinical and radiological results was conducted. Results : No significant differences in baseline characteristics were observed between the two groups. As expected, mean duration from onset to vertebroplasty and mean duration of hospital stay were significantly longer in the DVPG ($17.1{\pm}2.1$ and $17.5{\pm}4.2$) than in the EVPG ($3.8{\pm}3.3$ and $10.8{\pm}5.1$, p=0.001). Final clinical outcome including visual analogue scale (VAS), Oswestry Disability Index, and Odom's criteria did not differ between the two groups. However, immediate improvement of the VAS after vertebroplasty was greater in the EVPG ($5.1{\pm}1.3$) than in the DVPG ($4.0{\pm}1.0$, p=0.002). The proportion of cement leakage was lower in the EVPG (30.4%) than in the DVPG (59.3%, p=0.039). In addition, semiquantitative grade of cement interdigitation was significantly more favorable in the EVPG than in the DVPG (p=0.003). Final vertebral body collapse and segmental kyphosis did not differ significantly between the two groups. Conclusion : Our findings suggest that EVP achieves a better immediate surgical effect with more favorable cost-effectiveness.
Background: The normal vertebral anatomy of Korean raccoon dogs and their variants require research attention as a prerequisite for identifying pathologies and anomalies. Objectives: This retrospective study aimed at describing the vertebral formula and congenital vertebral anomalies in Korean raccoon dogs (Nyctereutes procyonoides koreensis). Methods: Radiographs of 82 raccoon dogs (42 males, 40 females) acquired from May 2013 to June 2020 in the Gangwon Wildlife Medical Rescue Center were reviewed to evaluate the cervical, thoracic, and lumbar vertebrae of the spine. Results: Normal morphology of all vertebrae was observed in 50 of the 82 raccoon dogs, and the vertebral formula was cervical 7, thoracic 13, and lumbar 7. Congenital vertebral anomalies were found in 32 raccoon dogs: transitional vertebrae (TV) in 31 and block vertebrae in 2. Two raccoon dogs had 2 types of vertebral anomalies: one had TV and block vertebra, and the other had 2 types of TV. Twenty-nine raccoon dogs had thoracolumbar TV (TTV) and 3 had lumbosacral TV. TTV was morphologically classified into 4 different types: unilateral extra-rib in 5 raccoon dogs, bilateral extra-ribs in 14, bilateral elongated transverse processes in 4, and an asymmetric mixed formation of extra-rib with elongated transverse process in 6. Conclusions: This study showed that TTV is common in Korean raccoon dogs, and that the vertebral formula is relatively diverse. The bilateral extra-ribs type TTV is the most common variant, which is almost similar to normal rib to be confused the radiographic evaluation.
Objects : Because of the nonspecific nature of symptoms in tuberculous spondylitis, a delay in the diagnosis can result in progressive neurologic deficits. The authors evaluate the clinical and the radiological results of the 10 cases of surgically treated tuberculous spondylitis. Clinical materials & Methods : We retrospectively analyzed the medical records of 10 patients with tuberculous spondylitis who were treated between February 1996 and March 2000. Six patients were female, and four were male. Mean age was 43 years old, and mean follow-up period was 20.5 months. All patients were treated with 12 months of antituberculous medication postoperatively, and were followed by complete blood count, ESR, spine X-ray and MRI. Results : The lumbar spine was involved in 5 patients, the thoracic in 4, and the thoracolumbar in one. The infected vertebral bodies were 2.8 in average. The associated lesions were pulmonary tuberculosis in 3 cases, and renal tuberculosis in one. Five patients were treated by anterior debridement and fusion with bone graft using anterior instrumentation, 2 with anterior debridement and fusion with bone graft(Hong Kong procedure only), 1 with Hong Kong procedure with posterior spinal instrumentation, and 2 were managed with posterior debridement and posterior spinal instrumentation. All patients improved after operation, and the average kyphotic angle decreased postoperatively. Postoperatively, one patient had a fistula at the operative site. Conclusion : The debridement and minimal level fusion of motion segment with instrument fixation is one of surgical option for tuberculous spondyltis to preserve the spine motion segment as much as possible. Spine instability and kyphosis were prevented by anterior and posterior spinal instrumentation. But, large number of cases and longer period follow-up study in future will be needed to confirm the long term results.
On rare occasions, percutaneous vertebroplasty (PV) may be associated with adverse spinal and extraspinal events. Subarachnoid hemorrhage (SAH) has not been reported complication following a PV. This is a report of two elderly women with spine compressions who developed idiopathic SAH after injecting polymethylmethacrylate into the thoracolumbar region transcutaneously. PV was performed as an usual manner on prone position under local anesthesia for these patients. During the interventions, two patients complained of a bursting nature of headache and their arterial blood pressure was jumped up. Computed tomography scans revealed symmetric SAH on the both hemispheres and moderate degree of hydrocephalus. Any intracranial vascular abnormalities for their SAH were not evident on modern neuroangiography modalities. One patient received a ventricular shunt surgery, but both fully recovered from the procedure-related SAH. The pathophysiologic mechanism that induce SAH will be discussed, with suggesting the manner that prevent and minimize this rare intracranial complication after PV.
Spinal extradural arachnoid cyst (SEAC) is a rare disease and uncommon cause of compressive myelopathy. The etiology remains still unclear. We experienced 2 cases of SEACs and reviewed the cases and previous literatures. A 59-year-old man complained of both leg radiating pain and paresthesia for 4 years. His MRI showed an extradural cyst from T12 to L3 and we performed cyst fenestration and repaired the dural defect with tailored laminectomy. Another 51-year-old female patient visited our clinical with left buttock pain and paresthesia for 3 years. A large extradural cyst was found at T1-L2 level on MRI and a communication between the cyst and subarachnoid space was illustrated by CT-myelography. We performed cyst fenestration with primary repair of dural defect. Both patients' symptoms gradually subsided and follow up images taken 1-2 months postoperatively showed nearly disappeared cysts. There has been no documented recurrence in these two cases so far. Tailored laminotomy with cyst fenestration can be a safe and effective alternative choice in treating SEACs compared to traditional complete resection of cyst wall with multi-level laminectomy.
Objective : Percutaneous vertebroplasty has recently been introduced as an interesting therapeutic alternative for the treatment of thoracolumbar vertebral body fractures in elderly persons with osteoporosis. The authors present the early results of this method. Method and Material : From July 1999 to April 2000, percutaneous transpedicular technique was used in 20 patients (2 men and 18 women) whose mean age was 67.5 years old(range 59-79) with painful vertebral compression(22) and burst(2) fractures. The interval between fracture and vertebroplasty ranged 1 day to 4 months. The procedure involved percutaneous puncture of the injured vertebra via transpedicular approach under fluoroscopic guidance, followed by injection of polymethylmetacrylate(PMMA) into the vertebral body through a disposable 11-guage Jamshidi needle. Result : The most common cause of fracture was slip down and the most frequent injured level was the twelfth thoracic spine. The procedure was technically successful bilaterally in 18 patients(9 thoracic and 15 lumbar spines) with an average injection amount of 7.7ml PMMA in each level. Seventeen(94.4%) patients reported significant pain relief immediately after treatment. Two leaks of PMMA were detected with postoperative CT in spinal epidural space and extravertebral soft tissue without clinical symptoms. Conclusion : Although this study represents the early results, percutaneous vertebroplasty seems to be valuable tool in the treatment of painful osteoporotic vertebral body fractures in elderly, providing acute pain relief and early mobilization.

This paper presents the clinical outcome of an 82-year-old female who experienced sudden back pain combined with lower limb paresthesia and weakness after epidural steroid injection. The magnetic resonance imaging of the thoracolumbar spine showed a spinal epidural hematoma (SEH) extending from T8 to L4. She was treated non-operatively in the traditional Korean medicine (TKM) hospital. The patient's progress was assessed using the Numerical Rating Scale (NRS), American Spinal Injury Association (ASIS), Spinal Cord Independence Measure version III (SCIM III), and self-reported symptoms. During the 22-day hospitalization period,the NRS score decreased from 7 to 2 points, the motor score on the ASIS scale increased from 65 to 95 points. The subjective sense of lower extremities was felt by 1 increased to 8. The SCIM III score increased from 32 to 69 points. These results suggest that TKM could effectively reduce pain and aid the rehabilitation of patients with SEH.
Backgrounds: To evaluate the effectiveness of conservative treatment in osteoporotic thoraco-lumbar compression fractures and to identify the factors influencing the progression of compression. Materials and Methods: From January 2003 to October 2004, Patients who were admitted to our hospital for osteoporotic thoraco-lumbar compression fractures were reviewed retrospectively with follow-up more than 12 months (ave. 14.6 months). With simple x-ray lateral view, we evaluate wedge compression ratio (WCR) and kyphotic angle (KA) at initial and final follow-up. We separate the patients into two groups baesed on the amount of progression of vertebral compression and evaluate a relation with BMD, vertebral fracture level, initial WCR, initial KA. All datas were statistically analyzed. Results: An average of T-score was -3.5 and the changes of KA between initial and final follow-up were average $3.5^{\circ}$. Compression of anterior column were progressed to 8.5%. The changes between initial and final WCR in Group I (N=24) was 17.8%, and Group II (N=18) was 3.3%. T-score in group I was -3.4 and group II was -3.8 (p=0.228). vertebral fracture level were 10 T12, 12 L1, 2 L2 in group I; 6 T12, 6 L1, 6 L2 in group II (p=0.156). Initail WCR was 0.74 in group I, 0.63 in group II, and there was statistical difference between two groups(p=0002). Initial kyphotic angle was $13.9^{\circ}$in group I, $16.2^{\circ}$in group II repectively (p=0.392). Conclusion: The conservative treatment with short-term bed rest and early embulation is effective and valuable method to patients who have osteoporotic thoraco-lumbar compression fractures. There was no statistical difference between two groups according to BMD, vertebral fracture level, KA. But in comparison with initail WCR between two groups, there was statistical difference. That means, in the case of small initial compression of anterior column, the progression of compression was bigger than else. In these patients, more strict use of appropriate brace and careful follow-up should be needed.
The present study was performed to investigate the prevalence rate of idiopathic scoliosis and to determine the effect of exercise training on scoliotic angle in elementary school children. In this study, two out of five elementary schools in Seosan city were chosen by random sampling. Seven hundred sixty four students (from four grade to the sixth grade student) were selected in two schools. Screening tests were conducted to find idiopathic scoliosis. Among the 764 individuals, 139 subjects who showed positive sign in physical examination took whole spine radiography. Thirty six subjects who had a curve of 10 or greater and consented to participate in the exercise program were selected for the exercise program. The exercise program was performed four times a week for 5 months. The results of this study were as follows: 1) One hundred thirty nine subjects showed positive sign in the scoliosis screening test. 2) The overall prevalence of curve of $10^{\circ}or$ greater in X-ray finding was 8.15%. The prevalencies of curve of $10^{\circ}or$ greater in male and female were 7.1% and 9.2%, respectively. 3) Scoliosis curves were observed at thoracic area (48.4%), at thoracolumbar area (27.4%) and at lumbar area(24.4%). 4) Right side curve was 59.7%, and left side curve was 40.3%. 5) After the 5 month exercise program for scoliosis, the Cobb's angle was significantly decreased. 6) There was no significant difference of Cobb's angle change respect to sex, grades, and scoliosis curve site. Results shown here indicates that an early detection and early exercise for scoliosis can result in decreased the Cobb's angle in elementary school children.
