Seventy consecutive ipsilateral fracture of the femur and tibia in sixty-eight patients from December 1974 through December 1984 treated at Severance Hospital were analysed in clinical and radiological aspect. 1. Fifty-nine patients were male and nine patients were female. The male patients were more injured in the ratio of 6: 1. The avarage age was 34. 2. The main cause of injuries were traffic accidents; 59 patients. (86.8%). 3. The majority of the fractures were shaft fracture; for example, femur shaft 57% and tibia shaft 47%, The open fracture of the tibia was 34% and the femur was 17%. 4. There were 24 cases of concomitant fracture and dislocation of other sites. A fat embolism was disgnosed in 4% of the patients. Four patients had died one month after sustaining injuries. 5. Over-all, a good or excellent functional result was achieved in 76% of the patients treated with internal fixation of both fracture, 65% of the patients with intexnal fixation for the femur fracture only and 35% of the patients managed conservatively.

To investigate MR artifacts induced by metallic implants, scans were obtained using both the ferromagnetic Drake lip and the non ferromagnetic Yasargil clip. Scan were taken through the area of clips using geometrical phantom. The MRI was performed by spin echo technique and gradient echo technique on both 2.0T and 0.5T MR unit. The luthors evaluated the nature and differences of artifacts in each sequence and parameter. Artifacts induced by both lips were noted in the direction of frequency encoding gradient, and consisted of region of signal loss abutted in one side by survilinear region of bright signal. Geometric distortion of image was marked in the Drake clip, out was minimal in the Yasargil clip under both 2.0T and 0.5T. Artifacts were more pronounced in the gradient echo technique than those of the spin echo technique on both 2.0T and 0.5T. Although there were no differences n the nature of artifacts induced by the Drake clip among each parameter in the spin echo technique under 2.0T, artifacts were slightly more pronounced on T2 weighted image under the 0.5T field, but no differences were found in the nature of artifacts induced by the Yasargil clip in the spin echo technique under, both the 2.0T and 0.5T fields. Marked artifacts were induced through the small area of the Drake clip which were included in the scan plane, but induced artifacts were small when a small area of the Yasargil clip was included in the scan plane. It seemed likely hat artifacts were slightly more pronounced in the 2.0T than the 0.5T field in both clips, but objective evaluation of the difference was difficult, In conclusion, these results can be an essential basis for the interpretation of MR images or patents with metallic inplants.

We measured poiyethylene wear radiographically in 85 cementless primary total hip arthroplasties by the modified technique of Livermore et al. All the patients were followed up for at least five years (mean, 6.31 years; range, 5 years-8 years 2 months). The mean extent of linear wear was 0.88mm (range, 0.0083-3.2839mm), and the mean rate of linear wear was 0.14mm/year(range, 0.00-0.47mm /year). The mean volumetric wear was 539.42mm (range, 5.11 2022.09mm), and the mean rate of volumetric wear was 87.69mm/year(range, 0.65-290.12mm/year). The polyethylene wear was correlated inversely with the patients age only, but was not influenced by weight or gender of the patients, Harris hip score, thickness of the polyethylene, the abduction angle of acetahular cup, or the duration of in situ implantation. Osteolysis developed in the femur of 34 hips(40%) and in the acetabulum of 11 hips(12.9%). Radiographic loosening was found in one case in the femur and none in the acetabul pm. The extent of polyethylene wear was significantly correlated with frequencies and sizes of the osteolytic lesion and was not directly associated with radiographic loosening of the prostheses. Calcar resorption was observed in 39 hips(45.9%) and was not associated with polyethylene wear. These results indicated that polyethylene wear of primary total hip arthroplasty should be considered one of major causes of osteolysis and has no direct relationship with prosthesis loosening. To reduce the extent of polyethylene wear, the material characteristics of polyethylene should be improved or new, durable, articulating materials should be researched.

The superficial sural artery flap is supplied by the superficial sural artery that accompanies the sural nerve. The superficial sural artery connects distally with a peroneal artery septocutaneous perforator via a suprafascial network of vessels that permits the flap to be raised on its distal pedicle. We treated 10 patients who showed soft tissue defect of the lower third of the leg, around the ankle and the hindfoot with this flap. The causes of the soft tissue defect were trauma in 6 cases, pressure sore in 2 cases, squamous cell carcinoma in 1 case and osteomyelitis in 1 case. The sites of the soft tissue defect were the lower third of the leg in 5 cases, around the ankle in 2 cases and the hindfoot in 3 cases. The size of the soft tissue defect was from 5x6 cm to 8xl2 cm. All 10 flaps survived. Two flaps showed slight venous congestion which cleared in a few days. The time for flap dissection was 15 minutes in average. The results of our cases show that the distally based superficial sural artery flap is useful for the soft tissue coverage of the lower third of the leg, around the ankle and the hindfoot. The advantages of the flap are that the blood supply is reliable, elevation is easy and quick, the major arteries are not sacrificed and the donor site morbidity is negligible.

OBJECTIVES: To investigate the frequency and clinical characteristics of premenstrual syndrome(PMS)/premenstrual dysphoric disorder(PMDD) in high school students, and determine the correlates of PMS/PMDD in association with comorbid depression and anxiety. METHODS: A total of 1688 students were recruited from 5 high schools in Seoul, Korea. Subjects completed the questionnaire composed of scales to measure premenstrual symptoms, depression, and anxiety, as well as sociodemographic and reproductive variables. Subjects were categorized into 3 groups by using the Premenstrual Symptom Screening Tool(PSST) to determine the frequency and clinical characteristics of PMS/PMDD. Multivariate logistic regression was used to identify the correlates of PMS/PMDD. RESULTS: The frequency of moderate to severe PMS and PMDD was 20.1% and 6.4%, respectively. Irritability (78.8%), fatigue(76.4%), and emotional sensitivity(69.8%) were common premenstrual symptoms, and functional impairment in academic performance(67.1%) was dominant. Dysmenorrhea[odd ratio(OR)=3.68, 95% confidence interval(CI) 2.45-5.55], family history of PMS(OR=1.91, 95% CI 1.35-2.71), and use of oral contraceptive (OR=1.85, 95% CI 1.16-2.94) were associated with the increased risk of PMS/PMDD after adjustment for depression and anxiety. Negative attitude to menses(OR=15.60, 95% CI 3.61-67.42) was associated with the increased risk of PMS/PMDD, particularly in subjects without depression and anxiety. CONCLUSIONS: PMS was common, as the frequency of PMS more than moderate severity including PMDD exceeded 25%, and disrupted daily functioning in adolescents. PMS is associated with various sociodemographic and menstrual characteristics, and these associations are affected by comorbid depression and anxiety.

BACKGROUND: The purpose of this study was to discover ways to screen urine culture specimens through Gram stains, urine stick analyses and microscopic examinations for the laboratory cost saving. METHODS: One hundred and fifty-eight urine specimens for culture were included. Fifty uL of urine were inoculated onto one well each of 10-well slide, dried on the hot plate, and Gram-stained. The results combined with routine urinalyses including urine nitrite and leukocyte esterase, and pyuria, were compared with the routine culture results. RESULTS: The screening of bacteriuria by Gram stains, urinalyses and microscopic examinations revealed the high sensitivity (91.9%) and negative predictive value(95.5%) with cost saving of 41.8% of inoculating media. Not considering the Gram stains, the screening revealed 83.8% sensitivity and 92.5% negative predictive value, even if the cost saving of inoculating media were as high as 50.1%. CONCLUSION: It was demonstrated that it was sensitive and economic and produced rapid preliminary results to screen bacteriuria by the Gram stains combined with urinalyses and microscopic examinations.

We evaluated the clinical and radiologic results of 48 cases (31 patients) who had rheumatoid arthritis of the knee joint and were managed with cementless total knee arthroplasty between November 1988 and December 1994. The mean follow-up period was 3.7 years (range, 2 to 7 years). The knee score of the Hospital for Special Surgery improved from an average of 44 points (range, 5 to 77 points) preoperatively to 83 points (range, 50 to 97 points) at the time of the most recent followup examination. In knee score, 85.4% of cases had excellent or good grade (over 75 points). The range of motion improved from an average of 77 degrees to an average of 103 degrees postoperatively. In tibiofemoral angle, 95.8% of cases were between valgus I degree and 10 degrees. The implants were inserted in an optimal position. Continuous radiolucency was not visible beneath any implant and loosening was not found. In one case, heterotopic ossification was removed to improve the range of motion. There was one case of patellar fracture during operation. Even in relatively poor bone quality in rheumatoid arthritis of the knee, the cementless total knee arthroplasty revealed good clinical and radiologic results.
