Supracondylar fractures of the femur following total knee arthroplasty are rare complication with reported rates ranging from 0.3% to 2.5%. Union of the fracture in proper alignment, without disruption of prosthetic component fixation and with maintenance of 90 of knee motion, is impotant in treatment of this type of fracture. Modalties of treatment are conservative or operative methods and operative treatment are open reduction 4 internal fixation, intramedullary nailing, revision arthroplasty using a prosthesis with a long stem and closed reduction and external fixation, but there are controversies in the method of treatment. Between Apr. 1989 and Jul. 1994, 10 patients were treated for supracondylar fracture of the ipsilaterai femur following total knee atthroplasty and 2 cases of them had arthrop]asty at other hospital. Average age of patients was 53 years (29-68 years), nine patients were women and one was man. The preoperative diagnosis was rheumatoid arthritis in four, degenerative osteoaithritis in three, posttraumatic osteoarthritis in one and tuberculosis sequelae of the knee in two. In nine cases mechanism of injury were slip down and in one was fall down. The interval hetween arthroplasty and fracture was an average of 22 months (9-79months). Two cases we.re treated with closed reduction and cast immobilization, one case was treated with open eduction and in1ernal fixation and seven patients of' ten cases were treated with closed intramedullay Ender nailing. The average foIlow-up period after fracture was 25 months (3 - 74months). We evaluated the results as the range of motion, bony union at simple radiograph and Knee Rating Score of Hospital for Special Surgery at last follow up. Eight cases of supracondylar fracture occuned among 350 patients, 514 cases of total knee arthroplasty which were operated at Kyung Hee Univcrsity Hospital between Apr. 1989 and Jul. 1994 and incidence was 1.6%. At the last follow up, all 10 cases achieved bony union and 7 cases using Ender naiIing achieved clinical bony union which enabled patients to do weight-bearing without pain at postoperative 6-8 weeks and radiological union was achieved at postoperative 12 weeks. Range of motion were average 105 degrees (80 J.20 degrees) hefore fracture and 86 degrees (6S 120 degrees) at the last follow up and HSS Knee rating score were average 80.3 points (59 94 points) before fracture and average 78.8 points (66-89 points) at the last follow up. At 7 cases using Ender nailing, range of motion were average 106 degrees (90 11S degrees) hefore fracture and 91 degrees (6S-105 degrees) at last follow up and HSS Knee rating score were average 80.6 points (59-94 points) before fracture and average 80.3 points (72-89 poiints) at the last follow up. Closed iintramedullary Ender nailing is a gecommendable operative method in the treatment of supracondylar fracture following total knee arthroplasty considering to good bony union, satisfactory functional result, easy operative technique and less postoperative complication.

Posterior instability of the shoulder is far less common than anterior or multidirectional instability. There is still controversy in the diagnosis and treatment of recurrent posterior instability, and many treatment protocols have been advocated. However the failure rate as high as 50% was reported. The purpose of this study is to introduce characteristic physical findings of posterior instability, to present our operative techniques, and to report the efficacy of a superior shift of the postero-inferior capsule in the treatment of recurrent posterior instability. From June 1995 to September 1996, five patients, six shoulders underwent postero-inferior capsular shift for posterior instahility and were evaluated at an average of 17 months(ranged from 9 to 26 months) after operation. The average age was 22.4 years. Preoperatively, mean scores of pain, stability and function according to American Shoulder and Elbow Society (ASES) scoring system were 21, 9, and 16 points respectively and mean overall ASES score was 46 points. After surgery, the average range of motion was 175 of forward elevation and 74 of external rotation and internai rotation in back was up to the sixth thoracic level. Postoperative mean scores of pain, stability and function were 29, 34 and 25 points respectively and mean overall ASES score was 88.5 points. No patient had a recurrence of posterior instability. All patients had satisfactory results with significant improvement in stability and function except one case who had multidirectional instability that mainly involved the posterior component

Intentional delay of aftercoming siblings in multiple gestation is an infrequent occurrence in obstetrics. After delivery of an immature twin, conventional treatment calls for induction and delivery of the aftercoming sibling. However, several case reports have documented the feasibility of an expectant management. And also, as in our case, an aggressive treatment consisting of cerclage, tocolysis, and broad-spectrum antibiotics has been shown to prolong pregnancy. We experienced an unavoidable delivery of a nonviable first twin after premature rupture of membranes at 16 weeks' of gestation. The placenta was left undisturbed. Twin B was confirmed to be alive within the intact second sac. Tocolysis was started and cervical cerclage was done directly after delivery of twin A. Pregnancy was successfully prolonged, which enabled the second fetus to remain in utero and grow for another 145 days. To our knowledge, this was the longest interval between deliveries in a twin pregnancy reported in the literature. A healthy 3,050 gm male was delivered by cesarean section at 37 weeks' of gestation. Below we present this case in detail and discussed with respect to the aggressive approach undertaken to prolong gestation.

In order to evaluate the confounding factors of neurobehavioral tests and the neurobehavioral effects in the workers exposed to organic solvents, NCTB was carried out on 100 workers. 46 workers had never been exposed to neurotoxic substances, and the others were being exposed to the solvents, mainly toluene. Simple reaction time, digit symbol, Santa Ana dexterity test and persuit aiming were different with age in non exposure group. Simple reaction time was carried out well in males, and digit symbol and persuit aiming were in females. There was no difference at educational level when the subject was educated over 12 years. Santa Ana dexterity and Benton visual test differed according to exposure level to toluene, however simple reaction time didn't. The acute neurotoxic effect was not excluded in this study. But, NCTB could be used to evaluate and prevent neurobehavioral changes in workers exposed to neurotoxic solvents in Korea.

Forty five cases of adult tibial shaft fractures were treated with flexible intramedullary nails under image intensifier at the department of orthopaedic surgery, Capital Armed Forces General Hospital during between April 1986 to July 1988. The results were summarized as follows: 1. 45 cases were all male, the average age was 24.3 years and the most common cause of fractures was sports injury(20 cases) and the second most common cause was traffic accident(18 cases). 2. 11 cases out of 45 cases were open fracture and 34 cases were closed fracture. Eight cases of open fraeture were grade I and three cases were grade II. Twenty eight cases were comminuted fracture. The most common level of the fracture was middle third of the tibial shaft. 3. Average interval from injury to Ender nailing was 13.5 days and the mean duration of permission to full weight bearing was 9.2 weeks. 4. Out of 2 cases of delayed union, the average time of clinical bone union was 9.7 weeks and that of roentgenological bone union was 14 weeks. 5. 11 cases of complication were noted among the 45 cases of tibial shaft fracture which were treated by PGP nailing such as angulation, rotation, ankle joint stiffness, delayed union, shortening, and soft tissue infection. 6. PGP nailing is considered to be a valuable method in treating tibial shaft fracture because of their relative ease of nailing, allowing early weight bearing and decreased complication.

PURPOSE: To correlate the findings of perfusion-weighted imaging (PWI) with clinical outcomes in patients with acute lacunar infarction. MATERIALS AND METHODS: Eleven patients (7 males and 4 females) with acute lacunar infarction who were examined within 50 (mean, 29) hours of the onset of symptoms underwent conventional MRI, diffusion-weighted imaging (DWI) and PWI. Gadolinium (0.2 mmol/kg) was injected at a rate of 2 ml/sec, and PWI was performed using a gradient-echo EPI pulse sequence and the following parameters: TR/TE, 2000/60; flip angle, 90 degree; matrix size, 128X128. Relative cerebral blood volume (rCBV) maps were derived from gadolinium bolus perfusion-weighted images where rCBV ratios between infarcted areas were detected by DWI, and contralateral control areas were obtained. In each case, the resulting rCBV ratio at a lesion site was compared with the clinical outcome determined on the basis of the difference between National Institute Health Stroke Scale (NIHSS) scores at admission and discharge. RESULTS: With the aid of the time-intensity curve obtained at PWI, the rCBV maps revealed a hypoperfused area in 10 of 11 patients, and there was positive correlation (r=0.81) with clinical outcome. CONCLUSION: Although PWI has a lower detection rate than DWI, it may be a useful modality for helping determine prognosis in cases of acute lacunar infarction.

Pseudomeningocele after spine surgery can cause various symptoms, but it can also be silent. We experienced 3 cases of pseudomeningocele with different symptoms and we analyzed the characteristics of each case. A small pseudomeningocele without connection to the subarachnoidal space can show no symptoms. A pseudomeningocele with a small dural tear and it's abutted on the duramater at a small portion can produce sciatica and limitations of straight leg raising due to adhesion of the cauda equina around the dural tear. In addition, a large pseudomeningocele with a big dural and lamina defect can produce back tenderness furthermore, a patient with such a lesion can have low back pain and leg pain that are aggravated by an increment of abdominal pressure or by impact to the body and even by walking. Pseudomeningocele should be suspected when symptoms recur after spine surgery and especially in the case of dural tear during an operation

OBJECTIVE: This study aimed to explore the effect of cognitive function, social activity participation and social support on quality of life (QoL) of community-dwelling elderly. METHODS: The data on 194 elderly were selected from the nationwide community cohort named Korean Longitudinal Study on Cognitive Aging and Dementia. All subjects were assessed QoL-Alzheimer's Disease (QoL-AD), Cumulative Illness Rating Scale, exercise habit, Mini-Mental State Examination, social activities, The Medical Outcomes Study-Social Support Survey. The data were analyzed with SPSS WIN V. 21.0 program. RESULTS: The mean of QoL among community-dwelling elderly was 35.49 (24–46) for QoL measured by QoL-AD. The variables of professional, residence status, physical health, exercise, cognitive function, social activity participation and social support explained 29.3% of variance in QoL of community-dwelling elderly. Among these factors, the significant predictors of QoL were social support (β=0.322, p<0.001), cognitive function (β=0.152, p=0.021), and religion activity (β=0.152, p=0.025). CONCLUSION: The study suggests that the focus of intervention program should be on cognitive function and social activity participation to improve QoL for elderly. Improving cognitive function and social activity will lead to the network of social support, consequently to increase QoL for elderly living in the community.

PURPOSE: Orbital computed tomography was useful for evaluation of orbital truama because it can visualize most soft tissues, foreign bodies and bone details. Advancements in computer software makes three diemensional CT available with more higher quality and reasonable cost. We studied the officency, merit and limitation of orbital three dimensional CT. METHODS: We evaluated the conventional orbital CT and three dimensional orbital CT of the patients visited department of ophthalmology and emergency room to orbital trauma or other orbital diseases. RESULTS: The three dimensional orbital CT was not superior to conventional orbital CT in evaluation of orbital soft tissue disease but useful for evaluation of orbital bony details. CONCLUSION: In cases of coexamination with conventional orbital CT, the three dimensional orbital CT was useful for diagnosis and surgical planning in orbital truamatized patient.
