We analysed forty-six cases of femoral neck fracture treated with internal fixation and followed for more than one year at Korea University Hospital from January 1979 to June 1986 and the following results were obtained. 1. Sex distribution was 23 cases(50%) male and 23 cases(50%) female, and average age was sixty years old (range from 21 to 91 years). 2. The most common cause of injury was slip down(76%). 3. The most common type of fracture was Garden's type III(46%) and Pauwels' type III (67%). 4. In cases of internal fixation, the most commonly used method was closed reduction and multiple pinning under the local aneshtesia(83%). 5. Bony union was established within 5.9 months in average. 6. Among forty six cases, 7 cases(15%) of avascular necrosis, 4 cases(9%) of malunion, and 2 cases(4%) of nonunion was occurred. 7. The clinical results were excellent in twenty cases(43%), good in sixteen cases(35%), fair in seven cases(15%), and poor in three cases(7%) according to Lunceford's assessment.

PURPOSE: To evaluate the effect of surgical treatment of ligature-induced peri-implantitis in dogs using fractal analysis. Also, the capabilities of fractal analysis as bone analysis techniques were compared with those of histomorphometric analysis. MATERIALS AND METHODS: A total of 24 implants were inserted in 6 dogs. After a 3-months, experimental periimplantitis characterized by a bone loss of about 3 mm was established by inducing with wires. Surgical treatment involving flap procedure, debridement of implants surface with chlorhexidine and saline (group 1), guided bone regeneration (GBR) with absorbable collagen membrane and mineralized bone graft (group 2), and CO2 laser application with GBR (group 3) were performed. After animals were sacrificed in 8 and 16 weeks respectively, bone sections including implants were made. Fractal dimensions were calculated by box-counting method on the skeletonized images, made from each region of interest, including five screws at medial and distal aspects of implant, were selected. RESULTS: Statistically significant differences in the fractal dimensions between the group 1 (0.9340+/-0.0126) and group 3 (0.9783+/-0.0118) at 16 weeks were found (P<0.05). The fractal dimension was statistically significant different between 8 (0.9395+/-0.0283) and 16 weeks in group 3 (P<0.05). These results were similar with the result of the evaluation of new bone formation in histomorphometric analysis. CONCLUSION: Treatment of experimental peri-implantitis by using CO2 laser with GBR is more useful than other treatments in the formation of new bone and also the tendency of fractal dimension to increase relative to healing time may be a useful means of evaluating.

With the increasing age of the population, abdominal aneurysms are increasing in frequency, especially in the old age. At present, surgical excision is recommended for all abdominal aneurysm as soon as possible after the diagnosis has been made because of its high incidence of rupture, a fatal complication. Authors had experienced 3 cases of ruptured abdominal aortic anurysm with a succesfully surgical repaire in intraduodenal ruptur of abdominal aortic aneurysm is Surgical Department, St. Mary's Hosp. Leterature was briefly reviewed.

PURPOSE: The purpose of this study is to evaluate the relationship between developmental lumbar spinalstenosis and its BMD value by using the single energy quantitative CT(SEQCT). MATERIALS & METHODS: Eighty normal volunteers(20-60years) were selected as a control group and 28 patients with developmental lumbar spinal stenosis were selected as a disease group. The two groups were divided into a younger (20-39years) and an older subgroup(40-60 years), and were further divided into male and female subgroups. All the cases showed no evidence of metabolic disease, fracture, herniated nucleus pulposus, degererative spondylosis, infectious disease, tumors orhad no history of absolute immobilization of more than two weeks. All underwent lumbar spine CT and SEQCT. We measured bone mineral density(BMD) at the cancellous bone of L1, 2, 3 and obtained the mean and its one standard deviation, and compared the data between each subgroup of the control and the disease group using ANOVA. RESULTS: There was a significant low BMD value in the younger male patient subgroup compared with the control subgroup(P<0.05). CONCLUSION: Developmental lumbar spinal stenosis in a young male may be a factor of decreasing BMD of the body of the spine.

The utility of computed axial tomography(CAT) in the diagnosis of spinal disorders has been the subject of considerable interest since the introduction of CAT scanning. Computed tomographic guided needle biopsy of 12 consecutive patients with a variety of undermined spinal disorders resulted in a 100% yield of positive tissue diagnoses, without signlficant complications. The principal advantage of cat guidance is the continuous direct observation of the needle tip position in relation to the target volume. We think that the application of computed tomographic guided needle biopsy in the lesions of the spine is of great value, because it is the single most accurate method of obtaining diagnosis other than by open surgical biopsy.

It has been emphasized that treatment of hemoral neck fracture is early anatomical reduction and rigid internal fixation to reduce severe complications such as avascular necrosis or non-union.Operative treatment were developed recently with development of radiological technique. This study reviewed twenty-nine patients of femoral neck fracture treated by internal fixation between December 1973 and December 1979. There are eleven casesof Garden's stage I or II fracture with multiple Knowles pinning and eighteen cases (All Gardens stage) treated with compression hip screw, and followed for a minimum of nine months with an average eighteen months. The results were as follows; 1. Eleven cases with minimal displaced fracture (Garden's stage I or II) treated by multiple Knowles pinning were revealed good results. 2. In total eighteen cases treated by compression hip screw, nine cases (Garden's stage I or II) were revealed good results and other nine cases (Garden's stage I or II) were revealed fair or poor results. 3. Eleven cases of mlutiple Knowles pinning and nine case of compressian hip screw used for undisplaced fracture (Garden's stage I or II) were revealed good results without regard to internal fixation devices. 4. Avascular necrosis were four cases in nine cases(44%) of displaced fracture. 5. Non-union were not found in this aeries.

Recurrent or a second attack of acute poststreptococcal glomerulonephritis have been known to be extremely rare. Acute exacerbation in chronic glomerulonephritis and recurrence of acute poststreptococcal glomerulonephritis would be distinguishable shable clearly by histopathological, immuno-fluorescent and electron microscopic, studies from renal biopsy material. Recently we dealt with two cases of a second attack of APSGN in a 9 year old girl and a 12 year old boy and reviewed the literature and the possible mechanism is discussed.

The authors report a case of ruptured large saccular aneurysm of anterior ethmoidal artery, ethmoidal artery associated with anatomically related arteriovenous malformation(AVM). The patient was a 49-year-male who presented with severe headache followed by deteriorated consciousness. Computerized tomography and Magnetic resonance imaging revealed intracerebral hemorrhage in left the frontal lobe and intraventricular hemorrhage and contrast enhancing ring-like mass in the frontobasal area. The cerbral angiography showed anterior ethmoidal artery aneurysm with abnormal vascularity in arterial phase. The patient was treated successfully by clipping of the aneurysm and removing of AVM, Among the reference, I have reviewed this paper is the first case report on the anterior ethmoidal artery aneurysm associated with AVM.

PURPOSE: To analyze the clinical and radiologic results after total knee arthroplasties using down-sizing femoral prosthesis for tight fitting in patients over 75 years old. SUBJECTS AND METHODS: The study tracked the histories of 99 elderly patients aged 75 and over who underwent total knee arthroplasties with at least five years of follow-up from January 1st, 2005 to December 31st, 2007. The average age of the 99 patients was 78.58 years, and 17 women an 82 men patients underwent 78 cases of total knee arthroplasties on the right and 77 cases of total knee arthroplasties on the left. The HSS score and VAS scoring systems were introduced for clinical analysis. We compared the results of the width of the radiolucent line in 7 sections around the femoral component, 7 sections around the tibia component and 5 sections in the patella component using the American Knee Society Radiographic Evaluation and Scoring system respectively. RESULT: The average period of postoperative follow-up study was 6.2 years. The average femoral prosthesis size in preoperative measurement was 2.41 while the size selected in surgery was 1.89. The average VAS score decreased from 8.15 in preoperative measurement to 2.85 in postoperative measurement. Clinical significant loosening or dislocation of femoral prosthesis was not observed. Although the radiolucent line was observed in 5 cases, the score was less than 4. CONCLUSION: Total knee arthroplasties using down-sizing femoral prosthesis does not increase osteolysis and dislocation of femoral prosthesis but does reduce pain and help patients return to normal activities. Therefore this study showed that total knee arthroplasties using down-sizing femoral prosthesis helped elderly patients aged 75 and over.

Ushers syndrome is an autosomal recessively inherited trait that characterized by progressive retinitis pigmentosa combining night blindness with a congenital, nonprogressive sensorineural hearing impairment of variable severity. Speech disorder, vestibular ataxia, mental deficiency, psychosis, and cataract are usually present. We experienced a case of type IV Ushers syndrome in 28 year-old woman that showed the night blindness with decreased visual acuity that had been developed 7-8 years before and congenital sensorineural hearing loss. In fundoscopic examination, characteristic bone corpuscle pigmentation in the periphery, and narrow arteries are found. Her electroretinogram and pure tone audiometric findings show non recordable wave forms and bilateral sensorineural hearing loss. She has mild mental retardation also.
