Vertebroplasty was introduced in 1987 for painful cervical hemangioma. Since then, there has been an explosion of interest in this remarkable procedure, which can be useful for the majority of vertebral fractures throughout the spinal column. This procedure is indicated for painful vertebral compression fracture(VCF) due to osteoporosis or malignancy, and for painful hemangiomas. Vertebroplasty is the injection of bone cement, generally polymethylmethacrylate (PMMA), into a vertebral body (VB). Kyphoplasty is the placement of balloons into the VB, followed by an inflation/deflation sequence to create a cavity prior to the PMMA injection. These procedures are most often performed in a percutaneous fashion under local anesthesia. Although these methods are minimally invasive procedure, numerous complications can occur. The common complications include bleeding at the puncture site, PMMA leakage, local infection, and adjacent vertebral body fracture. A grave complication, which is rarely reported, is pulmonary embolism by PMMA leakage. These procedures can reduce pain in about 90% of patients with osteoporotic VCFs. Additionally, improvements in mobility and in activities of daily living occur. The success rate is slightly less in patients with metastatic VCFs than osteoporotic VCFs. Much evidence favors the use of these procedures for pain associated with the aforementioned disorders. The risk/benefit ratio appears to be favorable in carefully selected patients. This article summarizes the indications, techniques, complications and outcomes for the vertebroplasty and kyphoplasty.

The following is our report a series of 220 patients who visited the neurosurgical out-patient department from January 1994 to June 1994 complaining of low back pain. We investigated how they were treated and what was the outcome on December 1995. Three certified neurosurgeons had managed these patients. Although the patients were not significantly different in terms of age, sex, and the duration of pain, the diagnostic methods(p<0.005), impression(p<0.01), and the methods of treatment(p<0.01) differred from doctor to doctor. The rates of admission and operation were 11.8% and 7.3%, respectively, and found to be consistent among doctors. We conducted telephonic interviews of 123 patients during December 1995 with the following outcome : improved in 69.1%, unchanged in 22.0%, and aggravated in 4.1%, together with six(4.9%) deaths. The cause of death was cancer in four cases, respiratory failure in one, and unknown in one. Sixteen patients underwent surgery in this hospital, while the other 12 patients were operated on in other hospitals. The outcome was favorable when 1) the patients were female, 2) the age was 21-40 years old, 3) presence of sciatica, 4) the duration was 1 week to 3 months, 5) the diagnostic impression was herniated lumbar disc, 6) drugs were not prescribed, and finally 7) managed by senior doctor. However, these differences were statistically not significant(p>0.1). Although low back pain is a very common complaint, there was enormous ambiguity with respect to its diagnosis and management. Neverthless, the outcomes were not significantly different. Despite the above, we still feel that low back pains should be more systematically classified and precisely dignosed. Also the therapeutic efficacies of different modalities of treatment should be critically reviewed.

Acute subdural hematoma (ASDH), chronic subdural hematoma (CSDH) and subdural hygroma (SDG) occur in the subdural space, usually after trauma. We tried to find a certain relationship among these three traumatic subdural lesions in 436 consecutive patients. We included all subdural lesions regardless of whether they were main or not. We evaluated the distribution, age incidence and interval from injury to diagnosis of these lesions, and the frequency of new subdural lesions in each lesion. ASDH constituted 68.6%, SDG 15.8%, and CSDH 15.6%, Age incidence of CSDH was similar to that of SDG, but differed from that of ASDH. Mean interval from injury to diagnosis was 0.4 days in ASDH, 13.4 days in SDG, and 51.6 days in CSDH. Focal brain injuries accompanied in 37.5% of ASDH, 5.8% of SDG, and no CSDH. In ASDH, 2 recurrent ASDHs, 17 SDGs and 9 CSDHs occurred. In SDG, 3 postoperative ASDHs and 8 CSDHs occurred. In CSDH, 2 postoperative ASDHs, 2 SDGs and 1 CSDH occurred. These results suggest that the origin of CSDH is not only ASDH, but also SDG in upto a half of cases. SDG is produced as an epiphenomenon by separation of the dural border cell layer when the potential subdural space is sufficient. A half of CSDHs may originate from ASDHs. ASDH may occur in CSDH by either a repeated trauma or surgery. Such transformation or development of new lesions is a function of a premorbid condition and the dynamics between the absorption capacity and expansile force of the lesion.

The authors present the case of sciatica due to bicortical sacral screw impingement on the lumbosacral plexus across the anterior sacrum. The placement of sacral screw across the anterior sacral cortex carries significant inherent risks to neurovascular and visceral structures. However, the clinical reports of lumbosacral plexus involvement by the misplaced screw are not well documented in the literature. This is an unique case of sciatica due to sacral screw impingement on the lumbosacral plexus after motor vehicle accident(MVA), and confirmed by CT scan and intraoperative electrical stimulation. We reviewed sacral anatomy and preventive measures for avoiding complication of this type are discussed.

We present a retrospective study on the results of posterior instrumentation with various devices after thoracolumbar spinal injuries. From Jaunary 1985 to December 1990, we operated 61 patients in Soonchunhyang University Chonan Hospital. Fourty-six patients were followed at least three months(three to 40 months). Rod system was used in 21 patients and pedicle screw system was used in 27 patients. In two patients, both systems were used. We divided them into two group ; Group A for the patients operated with rod system and Group B for the patients operated with pedicluar screw system. We analysed and compared the results of these two groups. There were no significant differences in the age, sex, causes of injury, levels and types of injury, and the incidence of cord injury. The final wedge deformity was less severe in Group B than A(P<0.02). However, the final angular deformity did not significantly differ in two groups. The mean hospital stay of Group B was shorter than that of Group A, but the difference was not statistically significant. Although there was no statistical significance, the final wedge deformity was severe in patients who were older than 40 years of age, who follwed up for more than 300 days, and who had cord injury. The final wedge deformity and angular deformity were severe in patients whose preoperative deformity was great(P<0.05 and P<0.02, respectively). The angular deformity was also severe Group A, in patients who had cord injury, who followed up for more than 300 days, and who were younger than 40 years of age, but these differences lack the statistical significance. Although the rate of complication in Group B(40.7%) was higher than Group A(28.6%), this diference was not significant. The most common complication was rod displacement in Group A and screw fracute in Group B. Pedicle screw system was superior to the rod system in this study. Improving the instruments and accumulating clinical experiences, pedicle screw system will be an effective method for thracolumbar stabilization.

It is never easy to assess the rate of disability from spinal injuries objectively. One reason is that the pain is an unmeasurable subjective symptom, and the other is that the disability is usually not confirmed by or correlated with radiological or laboratory examinations. The disability is an essentially subjective inconvenience or limitation, which is hard to measure objectively. However, compensation or reparation requires a scale to measure this unmeasurable disability, even with a universal validity and equity. There are several guidelines or criteria for a quantitative assessment of the disability. They differ from each other and have their own advantages and disadvantages. This difference may cause confusion or inequity. To improve the validity and equity, we propose a new design for the disability evaluation in patients with spinal injuries. We reviewed the Korean law for compensation in industrial accidents, McBride's disability table, the guideline proposed by American Medical Association, and a impairment rating table. Disabilities resulting from spinal injuries were classified into three types, i.e., morphologic sequelae(deformity), functional sequelae(dysfunction), and others. Only objective findings were considered as criteria for rating the disability. Disability resulting from deformity were rated from 0 to 20% by the degree of compression. Dysfunction can be rated by the number of lost motion segment from 10 to 60%. Disability from other compensable spinal pain were rated by objective physical findings or neurologic deficit from 0 to 25%. By eliminating the subjective or intentional complaints, this design can be a useful method minimizing the differences from the multiple examiners.

Two hundreds and four consecutive patients who sustained proven spontaneous subarachnoid hemorrhage with conservative treatment were studied retrospectively. The reasons for conservative treatment were poor condition for surgery, difficulties in surgery and operation refusal. Comparative study was done in proven 47 cases of aneurysmal SAH, 27 cases of SAH with negative angiography and 130 cases of SAH without angiography about age, aneurysm site & size, neurologic grade mortality & morbidity, etc. Death had occurred in 2 weeks after attack predominantly. Rebleeding was most common cause of mortality(64%, 68/107). Survivals had good quality of life(73%, 19/26).
