The morbidity of spondylolisthesis tends to increase in accordance with the popularization of sports and increase of mean life span by the development of medicine. We had applied surgical treatment for 39 cases of spondylolisthesis during the period of 8 yrs. from Jan. 1976 to Dec. 1983 at Department of Orthopaedic Surgery, National Police Hospital, among them 35 cases were followed up for mean 27 months. Twenty eight cases with posterolateral spinal fusion were isthmic spondylolisthesis and seven cases with posterior spinal fusion and facetectomy were degenerative type. We analysed them with clinical aspects and surgical treatment for 35 cases. The results were as follows: 1. The most common clinical symptoms were low back pain (96.7%) and tenderness (93.5%). 2. The degree of slipping was Grade I by Meyerding's classification in all cases and mean 12.5% by Taillard method. 3. In the 7 cases of isthmic spondylolisthesis, the degree of slipping increased on standing lateral view. And in these cases the clinical symptoms were aggrevated at welking. 4. In the degenerative spondylolisthesis with posterior spinal fusion and facetectomy, we found mean 70% spontaneous correction of slipping commpared with preoperative. 5. In postoperative evaluation we gained 94.3% above good according to Gill's criteria and no pseudarthrosis.

Myositis Ossificans Traumatica, ossifying hematoma and calcifying hematoma have been used interchangeably to dcscribe the process of calcification and ossification occuring within muscle tissue in response to trauma. Authors analysed 27 cases of traumatic myositis ossificans of the Quadriceps who were diagnosed and treated at the department of orthopaedic surgery, National Police Hospital from January 1978 to June 1984. The results are as follows: 1. In sex distribution, in all cases 27 were males, in age distribution they were between 19 and 25 years old. 2. The causes of trauma consisted of 11 in kicking and treading, 6 in falling and slipping, 6 in football, 4 in demonstration injury. 3. The duration from injury to initial visit was variable. The average duration was 2 weeks. 4. Quadriceps contusions in all cases were grouped according to severity of trauma as mild, moderate and severe. Among 27 cases, 4 cases were mild, 11 cases were moderate, 12 cases were grouped as severe. According to the severity of trauma, duration of treatment and restoration of affected knee joint motion were more prolonged. 5. Among 27 cases, 6 cases sustained reinjury. 6. Total 27 cases, average duration of treatment was 4.6 weeks. 7. In those patients presenting after 2 weeks from injury, the duration of treatment was 3.8 weeks, and in those patients presenting within 2 weeks it was 5.4 weeks. Thc moderate cases were required 3.8 weeks of the duration of treatment, severe cases were required 6.5 weeks. Reinjury cases, 6 cases required more prolonged treatment, 6.8 weeks. These results suggest that early treatment, low violence of trauma and prevention of reinjury were the factor of minimizing the impairment of knee joint motion and shortening the duration of treatment. 8. The earlist X-ray change was found of the 14th day from injury. (average the 27th day from injury). 9. Within 6 months, all cases regained full range of motion of knee joint. 10. With only conservative treatment applied on all cases, we get the satisfactory result.

Fracture of the scaphoid constitute 60% to 70% of all diagnosed carpal injury. The acute fracture will heal approximately 90% of the time if recognized early and properly immobilized. But nonunion are common since the symtoms do not alert patients to seek early medical treatment and the diagnosis is easily missed. Authors have experienced 19 cases of scaphoid nonunion and accomplished good result in all case by Russe procedure. The results were summerized as follow: 1 The cause of fratures was mainly due to fall down dinjury (36.8%). 2. The most common mechanism of the fracture was fall on the outstretched hand (52.7%). 3. Fractures were shown on the anterior-posterior, lateral and billiards view in all cases. 4. In ten cases, the fractures were found on the waist of scaphoid. 5. The cases of nonunion were probably inadequate intial treatment and delayed diagnosis. 6. The good results were obtained by bone graft according to Russe procedure.

The herniation of intervertebral disc is possibly diagnosed through the myelography, electromyography, discography or computerized tomography. Among them, the myelography is regarded as the popularized method that helps accurate analysis on the location and pattern of the lesion. The authors have studied 363 cases of herniated intervertebral disc with respect to the diagnostic accuracy of myelographic examination from January, 1982 to December, 1985 at the Department of Orthopedic Surgery and Radiology, National Police Hospital. The results were as follows; 1. The most common age group was 21 to 30 years old and ratio of male and female was 9.7: l. 2. The most common site of the lesion was between L4 and L5 vertebra in myelography. 3. Of the 363 cases which underwent the myelography, 305(84.0%) represented positive findings. 4. Myelographic accuracy was coincided with the clinical diagnosis regarding the location of herniation of intervertebebral disc in 262 cases(72.1%).

OBJECTIVES: It has been constantly reported that mismatch negativity (MMN) is impaired in patients with schizophrenia. However, the mechanism which relates impaired MMN and schizophrenia is not clear yet. The aim of this study is to investigate the association between MMN and clinical variables including functional status in patients with schizophrenia. METHODS: The present study assessed MMN using passive auditory oddball task in 26 patients with schizophrenia and 48 healthy controls. Repeated measures Analysis of Variance with age as a covariate was carried out for comparing peak amplitude and latency of MMN at 8 central line electrodes (FPz, Fz, FCz, Cz, CPz, Pz, POz, Oz) across groups. Pearson's correlation was performed to reveal the relationship between MMN and clinical variables including neurocognitive test results and the Global Assessment of Functioning score. RESULTS: MMN amplitude was significantly reduced in patients with schizophrenia compared with healthy controls. Pearson's correlation showed that subsets of short form of Korean Wechsler Adult Intelligence Scale scores and GAF scores were associated with MMN amplitude in patients with schizophrenia. CONCLUSION: These findings suggest that MMN amplitude is associated with current functional status including cognitive function in patients with schizophrenia.

BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.

PURPOSE: The aim of this study was to evaluate the periodontal and prosthodontic complications of multiple freestanding implants in the posterior jaws for up to 1 year of function. MATERIAL AND METHODS: Eight patients received 20 implants posterior to canines. Two or more implants were consecutively inserted to each patient. Single crowns were delivered onto the implants. Marginal bone loss, implant mobility, probing depth, and screw loosening were examined to evaluate the clinical success of such restorations for maximum 1 year of functional loading. RESULTS: All the implants performed well during the observation period. Neither periodontal nor prosthodontic complications were found except a slight porcelain chipping. While the marginal bone level was on average 0.09 mm lower around the implant after 6 months of loading, it was 0.15 mm higher after 1 year. CONCLUSION: Within the limits of this investigation, separate single-tooth implant restorations to replace consecutive missing teeth may clinically function well in the posterior jaw.

Combined spinal epidural block with use of the needle-through-needle technique has become increasingly more popular during recent years because it provides rapidity and density of spinal block, combined with the ability to extend the block and provide postoperative analgesia by use of the extradural catheter. However, the combined spinal epidural block has some disadvantages. Since the spinal needle makes a hole in the dura, the accidental migration of an extradural catheter into the dural opening made previously by the spinal needle is thought to be theoretical risk. We report a case during combined spinal epidural anesthesia for a total hip replacement in which the clear fluid in the epidural catheter was found and tested to confirm the nature of fluid and migration of catheter by the dextrostix test and the immunoelectrophoresis test(prealbumin test).
