Vertebral compression fractures can occur due to trauma, a malignancy, or most commonly, osteoporosis. These fractures are frequently seen in elderly women; 30% of postmenopausal women are affected by vertebral compression fractures. These fragile fractures frequently result in both acute and chronic pain, but more importantly, are a source of increased morbidity and possibly, mortality. These injuries can be treated both conservatively and with surgery. The use of percutaneous vertebral augmentation offers a minimally invasive approach for the treatment of vertebral compression fractures. We experienced two cases of compression fractures diagnosed during the treatment of thoracic postherpetic neuralgia. Two patients suffering from postherpetic neuralgia with a sharp and stabbing pain in the thoracic dermatomes that was unresponsive to conservative treatment were transferred to our clinic. During the management of postherpetic neuralgia, we incidentally found thoracic compression fractures after obtaining fluoroscopic guided images. After a balloon kyphoplasty, the preoperative pain related to the postherpetic neuralgia was successfully relieved soon after the procedure, and there were no complications.

교통사고로 인한 척추골절 환자 S75에서 손상부위에 따른 진단방사선학 및 보존적 치료 소견을 임상 문헌과 함께 고찰해 본 결과 다음과 같은 결론을 얻었다. 1. 흉요추 좌측방 단순필름에서 L1 요추에 설상변형 정도가 약 10%인 쐐기형 압박골절이 확인되었다. 2. L1 요추의 CT촬영 결과 추체부 전면에 궁형의 불규칙한 골 절편을 관찰할 수 있었으며, T12∼L1는 구조상 손상빈도가 높은 부위로 밝혀졌으며, Denis의 골절형태는 중간주와 후방주가 잘 보존된 전방주의 다발성 압박골절로 분류되었고, Cobb의 척추 만각증은 없었으며, Frankel의 신경손상 분류형태는 E형이었다. 3. 정형외과적 치료방법은 비수술 요법의 보존적 치료를 원칙으로 하였고, 수분·전해질, 영양 및 혈장제 대용으로 공급하는 수액과 함께 브스테로이드성 항염진통제, 근육 이완제를 투여하면서 철저한 침상안정을 유도하였다. 4. 수상후 3주째는 폴리에틸렌 back corset를 착용하고 조기재활을 시도하였으며, 수상 8주 후에도 경도의 불편감이 남아 있었으나, 추시 관찰한 결과 일정기간이 지나면서 점차 척추는 안정성을 찾게 되었다.

Purpose: We evaluate the characteristics of vertebral body fractures in two level flexion-distraction injuries of the thoracolumbar spine Methods: The findings of radiographs, computed tomographs, and MRIs of 43 patients with flexion-distraction injuries combined with vertebral body fractures were retrospectively evaluated. We divided the patients with bursting fractures into two groups, the distractive group (posterior vertebral height ratio >1) and the compressive group (vertebral height ratio <1). Results: There were 23 compression fractures and 20 bursting fractures. In bursting fractures, the distractive group had 5 cases, and the compressive group 15 cases. In 24 cases (55.8%), the interspinous distances were widened. The average of the canal encroachment was 4% in the distractive group and 40% in the compressive group. At last follow-up, the average loss of correction was 2.0 degree in compression fractures and 2.7 degree in bursting fractures. Conclusion: The configurations of vertebral body fractures in flexion-distraction injuries of the thoracolumbar spine were varied as to the location of the axis of flexion. Because bursting fractures in flexion-distraction injuries had distractive or compressive features, one should consider that in establishing operative plan.

Purpose : To assess therapeutic effects of percutaneous polymethylmethacrylate(PMMA) vertebroplasty on the pain caused by osteoporotic thoracic and lumbar vertebral body compression fractures in a large scale of a prospective clinical design, and to determine clinical factors influencing its therapeutic effects. Methods : A prospective clinical study was carried out in 349 vertebral levels of 159 patients between April 1998 and July 1999. The compression fractures were confirmed with bone scan and spine CT, and bone marrow density was measured. Visual analogue scale(VAS) score was used for pre- and post-operative assessments of the pain. All 159 patients were assessed immediately after surgery, and 140 patients of them were followed-up for about 6 months in average. Results : Partial and complete pain relief was sustained immediately after operation in 73%, through follow-up period in 88% of the patients. Pain relief was not proportional to the amount of PMMA or the rate of increase in the height of the compressed vertebral body. It appears that 3 to 6cc of PMMA was proper enough to sustain pain relief. Better clinical improvement was achieved in the patients treated within 6 months after occurrence of vertebral body fracture. The most frequent surgical complication was epidural leakage of PMMA, and the most serious complication was extravertebral leakage into the paravertebral muscles, which appeared to exert the worst influence on the outcome. However, surgery was not required in these patients. Conclusion : Therapeutic effects of PMMA percutaneous vertebroplasty on osteoporotic vertebral body compression fractures were confirmed in a relatively large scale of prospective clinical study. It appears that good outcome can be achieved in patients treated within 6 months after fracture, treated each level with 3 to 6cc of PMMA in amount. without serious complications.

Osteoporotic patients who undergo percutaneous vertebroplasty (PVP) have the risk of a repeated collapse of their adjacent vertebral body due to alteration of load transfer into the adjacent vertebral body. The authors have experienced a rare case of repeated osteoporotic vertebral compression fractures (VCF) resulting in extreme multi-level PVP. A 74-year-old female developed severe back pain after slipping down one month ago. Her X-ray and MR images indicated a T11 VCF. She underwent successful PVP with polymethylmethacrylate (PMMA). Two weeks later, she returned to our hospital due to a similar back pain. Repeated X-ray and MR images showed an adjacent VCF on T12. A retrial of PVP was performed on T12, which provided immediate pain relief. Since then, repeated collapses of the vertebral body occurred 12 times in 13 levels within a 24-month period. Each time the woman was admitted to our hospital, she was diagnosed of newly developed VCFs and underwent repeated PVPs with PMMA, which finally eased back pain. Based on our experience with this patient, repeated multiple PVP is not dangerous because its few and minor complications. Therefore, repeated PVP can serve as an effective treatment modality for extreme-multi level VCFs.

Objective : Although a significant correction of local kyphosis has been reported previously, only a few studies have investigated whether this correction leads to an improved overall sagittal alignment. The study objective was to determine whether an improvement in the local kyphotic angle improves the overall sagittal alignment. We examined and compared the effects of thoracic and lumbar level kyphoplasty procedures on local versus overall sagittal alignment of the spine. Methods : Thirty-eight patients with osteoporotic vertebral compression fractures who showed poor response to conventional, palliative medical therapy underwent single-level kyphoplasty. The pertinent clinical data of these patients, from June 2006 to November 2006, were reviewed retrospectively. We measured preoperative and postoperative vertebral body heights, which were classified as anterior, middle, or posterior fractured vertebral body heights. Furthermore, the local and overall sagittal angles after polymethylmethacrylate deposition were measured. Results : More height was gained at the thoracic level, and the middle vertebral height regained the most. A significant local kyphosis correction was observed at the fractured level, and the correction at larger spanning segments decreased with the distance from the fractured level. Conclusion : The inflatable balloon kyphoplasty procedure was the most effective in regaining the height of the thoracic fractured vertebra in the middle vertebral body. The kyphosis correction by kyphoplasty was mainly achieved in the fractured vertebral body. Sagittal angular correction decreased with an increase in the distance from the fractured vertebra. No significant improvement was observed in the overall sagittal alignment after kyphoplasty. Further studies in a larger population are required to clarify this issue.

본 논문에서는 골다공증성 척추압박골절에 대한 척추성형술시 골강화제인 PMMA 주입방법을 제안하였다. 척추성형술의 정량적 분석을 위해서는 유한요소해석을 사용하였으며 1m간격의 척추체 CT를 바탕으로 보다 정교한 척추체 모델을 제시함으로써, 단순화된 척추의 기하학적 형상과 간단한 재료 물성치를 사용하는 기존의 연구의 한계를 극복하고자 하였다. 본 연구 결과를 토대로 추체내 망상골에 주입되는 PMMA의 주입형태, 주입위치를 정량적으로 평가하여 이상적인 수술방법을 제시하였다. PMMA의 구입위치는 망상골의 앞쪽-위쪽에 많은 양이 집중하여 주입되었을 때, 가장 효율적으로 추체를 보완해 주는 것으로 나타났다.

Background: Kyphoplasty is a minimally invasive procedure that can stabilize osteoporotic and neoplastic vertebral fractures. We retrospectively evaluated the clinical outcomes of kyphoplasty for the treatment of vertebral compression fractures in cancer patients. Methods: We reviewed the clinical data of 27 cancer patients who were treated with kyphoplasty (55 vertebral bodies) between May 2003 and Feb 2008. The clinical parameters, using a visual analog 10 point scale (VAS) and the mobility scores, as well as consumption of analgesic, were evaluated preoperatively and at 1 week after kyphoplasty. Results: A total 55 cases of thoracic and lumbar kyphoplasties were performed without complications. The mean age of the patients was 66 years. All the patients experienced a significant improvement in their subjective pain and mobility immediately after the procedures. The pain scores (VAS), mobility scores and other functional evaluations using the Oswestry disability score and the SF-36 showed significant differences between the pre- and postoperational conditions. Conclusions: Kyphoplasty is an effective, minimally invasive procedure that can relieve the pain of patients with vertebral compression fractures and these fractures are the result of metastasis.

Objective : This retrospective study of 215 patients with 383 symptomatic osteoporotic vertebral compression fractures (VCFs) treated by percutaneous vertebroplasty (PVP), was performed to evaluate the clinical outcomes, and to analyze the various clinical factors affecting these results. Methods : The authors assessed the clinical outcome under the criteria such as the pain improvement, activity, requirement of analgesics, and the patient's satisfaction, and determined the relation to various peri- and intra-operative factors, and postoperative imaging findings. Results : The outcome was determined as 84.2% in relief of pain, 72.0% in change in activity, 65.7% in analgesics use, and 84.7% of satisfaction rate. More severe focal back pain, high uptake bone scan, and the lower mean T-score were related to the better pain relief following PVP. The longer the duration between fracture and PVP, the less severe focal back pain, low uptake bone scan, and leakage of PMMA into the paravertebral space were related to the less improvement in activity. Female and low uptake bone scan showed a correlation with more analgesic use. The longer the duration between fracture and PVP, low uptake bone scan, and the higher the mean T-score were correlated with the less the patients satisfaction. Conclusion : Our study suggests that PVP may be more effective in the acute phase of VCFs, more severe focal pain, and far advanced osteoporosis on BMD. Leakage of PMMA into the paravertebral spcae also could be affecting the surgical results.
