This is to present 44 cases of hip fractures, of these 28 being fractures of femoral neck and the remainder, intertrochanteric, which were treated at the Department of Orthopedic Surgery, Seoul National University Hospital for four years and 8 months from Jan. 1965 to Aug. 1969. 1. There were 33 males. and 11 females in the series. 26 cases(59.1) were over 51 years of age. 2. The femoral neck fractures were treated by means of Smith Petersen nailing in 16 cases, modified Girdlestone hip arthroplasty in 3 cases, Austin-Moore hip prosthesis in 6 cases and other methods in 3 cases. 3. Modified Girdlestone hip arthroplasty could be a treatment of choice for femoral neck fracture requiring hip arthroplasty for those unsuitable for extensive surgery. 4. The intertrochanteric fractures of femur except for 3 unstable fractures were treated successfully with the Smith-Petersen nail and plate, following anatomical reduction of fracture. In 3 unstable fractures, satisfactory stabilization and internal fixation was obtained by the method of medial displacement of proximal part of distal fragment of fracture.

Subperiosteal Cortical Defect is a symptomless rarefaction of cortical bone which begins most often on the external surface of the medial and posterior cortical walls of the lower end of the femur in children between the ages of 3 and 6 years. The name of Subperiosteal Cortical Defect was first used by Aegerter who differentiated it from non-osteogenic fibroma. The authors found out 5 positive cases of incidental findings among 62 cases of both knee joint X-ray of which 3 was male and 2 was female. Also we experienced 3 cases which necessiat d a correct diagnosis and differential diagnosis. Because this is a common lesion, it frequently accompanies more serious bone conditions, and because this is self-limited disease, treatment is not necessary. It was emphasized that its nature should be understood by all those dealing with bone disease lest it be overdiagnosed and overtreated.

Five cases of the spinal tuberculosis with severe kyphosis and paraplegia were treated with radical surgery at the Department of Orthopedic Surgery, Seoul National University Hospital. All the cases were involved at the thoracic spine and kyphosis were ranged 100 through 150 degrees. Severe fixed chest deformity and impaired pulmonary function were observed. By thoracotomy, aorta was seen to be adherent to the surrounding tissue and this was separated from the verterbral lesion with meticulous procedure. The focus was curetted radically exposing spinal cord which was decompressed with anterior transposition. Then the spine was stabilized with anterior interbody fusion. Postoperative intensive pulmonary care and antituberculous therapy are imperative for the good result. Spinal tuberculosi with severe kyphosis and paraplegia could be benefited with the radical surgery by the experienced surgeon.

PURPOSE: Planning target volume (PTV) for tumors in abdomen or thorax includes enough margin for breathing-related movement of tumor volumes during treatment. Depending on the location of the tumor, the magnitude of PTV margin extends from 10 mm to 30 mm, which increases substantial volume of the irradiated normal tissue hence, resulting in increase of normal tissue complication probability (NTCP). We developed a simple and handy method which can reduce PTV margins in patients with liver tumors, respiratory motion reduction device (RRD). MATERIALS AND METHODS: For 10 liver cancer patients, the data of internal organ motion were obtained by examining the diaphragm motion under fluoroscope. It was tested for both supine and prone position. A RRD was made using MeV-Green and Styrofoam panels and then applied to the patients. By analyzing the diaphragm movement from patients with RRD, the magnitude of PTV margin was determined and dose volume histogram (DVH) was computed using AcQ-Plan, a treatment planning software. Dose to normal tissue between patients with RRD and without RRD was analyzed by comparing the fraction of the normal liver receiving to 50% of the isocenter dose. DVH and NTCP for normal liver and adjacent organs were also evaluated. RESULTS: When patients breathed freely, average movement of diaphragm was 12+/-1.9 mm in prone position in contrast to 16+/-1.9 mm in supine position. In prone position, difference in diaphragm movement with and without RRD was 3+/-0.9 mm and 12 mm, respectively, showing that PTV margins could be reduced to as much as 9 mm. With RRD, volume of the irradiated normal liver reduced up to 22.7% in DVH analysis. CONCLUSION: Internal organ motion due to breathing can be reduced using RRD, which is simple and easy to use in clinical setting. It can reduce the organ motion-related PTV margin, thereby decrease volume of the irradiated normal tissue.

The purpose of this study was to collect the informations on the current status and the needs of the physically disabled elderlies in the rural community along with the prevalence rate of these population. One study group for the study of disability status evaluation was 139 physically disabled elderlies living in the main island of Kangwha, and the other group for the study on prevalence of disability was 542 elderlies living in Songhae myun. The prevalence of physical disability was 6.5% in Songhae myun. The neurologic disorder was the most frequent diagnosis among the physically disabled elderlies followed by the musculoskeletal disorder. The time for the medical service delivery was delayed; 45.3% of the subjects received medical service more than one month after the onset of disability. Only 18.0% of the disabled elderlies received the public disability service, and 15.8% of the subjects was waiting for further service. The most common need from the subjects was the medical service, followed by the service from the institution such as a nursing home and the financial support. Registration rate of the disabled was very low(7.7%). There were only three physical therapists for the rehabilitation services in studies areas. This study revealed that the public concepts for the disability and the rehabiltation service were inadequate. We hope that this basic data can be used for the planning of rehabilitation services in this community.

BACKGROUND: Acute renal failure is one of the leading causes of postoperative morbidity and mortality. The purpose of this study was to determine the risk factors that are associated with acute renal failure after colorectal surgery. MATERIALS AND METHODS: Five hundred seventy patients who operated colorectal surgery at the Yeungnam University Medical Center over three years from 2004 to 2006 were enrolled in this study. The effects of gender, age, ASA classification, concomitant disease, surgery type and duration, reoperation, urogenital manipulation, medication, hypotension, hypovolemia, transfusion, and postoperative ventilatory care on the occurrence of acute renal failure after colorectal surgery were studied. RESULTS: The major risk factors of acute renal failure after colorectal surgery were age of patients (P=0.003), ASA classification (P<0.001), concomitant disease (P<0.001), duration of the time surgery (P=0.034), reoperation (P=0.001), use of intraoperative diuretics (P=0.005), use of postoperative diuretics (P<0.001), intraoperative hypotension (P=0.018), intraoperative transfusion (P<0.001), postoperative transfusion (P<0.001), and postoperative ventilatory care (P=0.001). CONCLUSION: Multiple factors cause synergistic effects on the development of acute renal failure after colorectal surgery. Therefore, efforts to reduce the risk factors associated with acute renal failure are needed. In addition, intensive postoperative care should be provided to all patients.

PURPOSE: Massive pulmonary hemorrhage(MPH) within the first five days after birth is a major cause of early death in extremely low birth weight(ELBW) infants. The objective of this study was to determine risk factors for MPH in ELBW infants. METHODS: Data were retrospectively collected from 115 ELBW infants admitted to Seoul National University Bundang Hospital between January 2007 and September 2012. MPH was defined as the presence of hemorrhagic fluid in the trachea accompanied by acute respiratory failure within the first five days after birth. Initial echocardiography and cranial ultrasonography were performed in all subjects before MPH. Clinical characteristics of ELBW infants with and without MPH were compared and the risk factors for MPH were investigated. RESULTS: MPH occurred at 54+/-30 h after birth and was more frequent in ELBW infants with lower gestational age and lesser birth weight. Older maternal age was also associated with MPH. The presence of patent ductus arteriosus diagnosed using initial echocardiography was not significantly associated with MPH. The presence of intraventricular hemorrhage diagnosed using serial cranial ultrasonography was significantly associated with MPH. Logistic regression analysis indicated that among the variables that preceded MPH, only lower gestational age was independently associated with MPH. CONCLUSION: Lower gestational age was found to be a risk factor for MPH within the first five days after birth in ELBW infants.

PURPOSE: The aim of this study was to evaluate Cyanidin-3-O-beta-d-glucopyranoside on improvement and protection for erectile function. MATERIALS AND METHODS: Sprague-Dawley rats (12wks old) were divided into three groups (n=12 in each): normal control, diabetes (DM), and diabetes with Cyanidin-3-O-beta-d-glucopyranoside (C3G) concentration materials treatment (DM+C3G). DM and DM+C3G group received a single injection of streptozotocin (50 mg/kg), and 4 wk after induction of diabetes, DM+C3G group were treated with daily C3G (10 mg/kg) dissolved in water for 8 wk. After 12 wk of streptozotocin injections, rats in each group underwent intracavernosal pressure measurement (ICP) and then the corporal tissues were sampled. RESULTS: DM group showed markedly lower erectile parameters than those in the control group, whereas rats in the DM+C3G group showed improved erectile function by minimizing corporal apoptosis. CONCLUSIONS: The current study is the first to suggest that Cyanidin-3-O-beta-d-glucopyranoside may have a potency to improve and protect erectile function in a rat model of diabetic erectile dysfunction.

BACKGROUND: This prospective, double-blind randomized study was performed to evaluate the analgesic effect of lesser palatine nerve block for postoperative pain control after a pediatric tonsillectomy, and to compare the analgesic effects of pre-emptive versus postoperative blocks. METHODS: Forty-eight ASA class 1 children, scheduled for an elective tonsillectomy were randomized into three groups. Patients received lesser palatine nerve blocks, using divided doses of 0.05 ml/kg of 0.2% ropivacaine, 5 min prior to the beginning of tonsillectomy (Pre-block group) or immediately after surgery (Post-block group). Patients allocated into the Control group did not receive any nerve block. Postoperative pain was measured immediately after surgery, 3, 6, 12 and 24 hours following operation using a 0 to 4 points pain scale, based on a facial expression of pain scale ruler. Side effects and the number of analgesic injections were observed for 24 hours postoperatively. RESULTS: No significant differences in the pain scores were observed immediately after surgery and at 3, 6, 12 and 24 hours after operation in the three groups (P > 0.05). The number of analgesic injections was similar in the groups. CONCLUSIONS: The results of this study reveal that the lesser palatine nerve block was not effective for postoperative pain control following pediatric tonsillectomy, and that the pre-emptive block offered no pain control benefit over the postoperative block. Therefore, we do not recommend lesser palatine nerve blocks for the management of postoperative pain after pediatric tonsillectomy.
