In 1974, bipolar endoprosthesis was first introduced by Bateman & Giliberty. It has theoretical advantages including minimizing acetabular wear, possible reduction of incidence of stem loosening, lessening of dislocation and easy revision procedure. Various methods for the treatment of fracture of the femur neck have been developed & performed, but it is still called “the unsolved fracture” in certain situation. But the role of it as primary treatment of fracture of the femur neck continues to be controversial. Current clinical results encourage its continued use and expansion of indication. Authors reviewed and analysed 21 cases of bicentric endoprosthesis and 1 case of Giliberty endoprosthesis those have been operated at the Department of Orthopaedic Surgery, National Medical Center from 1981 to 1983. Following results were obtained, l. According to disorder distribution, 14 cases were neglected fracture of femur neck, 2 old fracture, 1 idiopathic femoral head necrosis and 2 avascular necrosis & 1 non-union complicated by femoral neck fracture. 2. Among 20 cases, 8 cases were operated within 1/2 1 month after injury and 6 cases within 1 3months 3. Harris lateral appmach was used in 16 cases (80%) and Modified Gibson approach in 4 cases (20%). There were no significant differences in morbidity during operation and postoperative complication. 4. We used femoral stems those head diameter was 22 and 32mm(Charnley & Miiller type) and head pieces those diameter was 48-51 mm in male and 44–48 mm in Ifemale. 5. 3 cases were stiff in inner bearing without acetabular erosion. 6. In 6 cases more than 2 years followup 1 degree CE angle of Wiberg was increased in 2 cases of youngage respectively without associated hip joint pain. 7. Although inclination of head piece was vertical in 8 cases, fracture and dislocation were not found. 8. The circumference of head piece and opposite femoral head was measured and compared. There were 12 cases (mean 12.6 mm) that of head piece larger than opposite femoral head and 3 cases smaller than opposite femoral head. 9. There was 4 cases of complication (3 patients) and still no reoperation and revision converted to T.H.R. 10. With regard to average 18 months of follow-up, 7 cases of 81–90 Harris hip-rating score, 6 of 91–100, 4 of 71–80 and 3 of 61–70.

A histopathological study was performed on nevus sebaceus to observe its aging effect based on 75 cases of neuvs sebaceus those were collected during the past 10 years from three university hospitals in Seoul. The results are as follows: 1) Clinical findings The incidence was most frequent in the teenage group. The 75 cases consisted of 41 males and 34 females with a sex ratio of 1.2:1. Most of cases developed in the head and neck areas with 62.7% on the scalp and 29.3% on the face. 2) Histopathologic findings. The epidermal changes such as acanthosis(40%), papillomatosis(73%), hypergranulosis(44%) were most remarkable in the second decade and gradually decreased with aging. The apparent proliferation of sebaceous gland was observed in 73% and it was most prominent in the second decade. Apocrine glands were absent before the first decade but apparently increased after then. Proliferation of eccrine gland was not significant in all the age groups. Mild increase of immature hair follicles were noted in 49% of our cases with gradually decreasing tendency in the older age. The dermal inflammatory infiltrates were noted from the 2nd decade(28%) and thereafter gradually increased. Associated neoplasms were one apocrine adenoma, one sebaceous adenoma, two trichilemmomas and two arteriovenous hemangiomas. The majority of tumors occured in the third decade. Therefore, it is observed that neuvs sebaceous undergoes dynamic histopathologic changes according to the age of patient and later develop various secondary neoplastic changes. The pathogenesis of the nevus sebaceus is suggested to be closely related with developmental anomalies of primitive hair germ units in fetal stage.

Tissues actively involved in energy metabolism are more likely to face metabolic challenges from bioenergetic substrates and are susceptible to mitochondrial dysfunction, leading to metabolic diseases. The mitochondria receive signals regarding the metabolic states in cells and transmit them to the nucleus or endoplasmic reticulum (ER) using calcium (Ca2+) for appropriate responses. Overflux of Ca2+ in the mitochondria or dysregulation of the signaling to the nucleus and ER could increase the incidence of metabolic diseases including insulin resistance and type 2 diabetes mellitus. Mitochondrial transcription factor A (Tfam) may regulate Ca2+ flux via changing the mitochondrial membrane potential and signals to other organelles such as the nucleus and ER. Since Tfam is involved in metabolic function in the mitochondria, here, we discuss the contribution of Tfam in coordinating mitochondria-ER activities for Ca2+ flux and describe the mechanisms by which Tfam affects mitochondrial Ca2+ flux in response to metabolic challenges.

Double contrast arthrography has been widely accepted as a method to diagnose the internal derangement of the knee. It is a safe and technically simple procedure permitting accurate diagnosis of lesions of the menisci. In 20 cases operated upon, with the diagnosis of internal derangement of the knee, we performed double contrast arthrography before surgery. We analysed the cases concerning the diagnostic accuracy of arthrography, its clinical significance and discrepancies between arthrographic findings and postoperative lesions. The results were as follows: 1. The cases consisted of 16 cases of meniscal lesion, 4 cases of ligamentous lesion and 3 cases of loose body. 2. In the meniscal lesions, 14 of the 16 cases (87.5%) were diagnosed accurately by arthrography, Therefore arthrography was more useful in diagnosing meniscal lesions as compared with clincal symptoms (69%). 3. In cases of ligamentous lesions arthrography was not significant-ly helfpful, in contrast clinical signs afforded important clues. 4. We encountered 1 case of false positive and 1 case of false negative.

The peripheral vascular occlusion in the diabetes was studied in fifty-nine male and forty-six female diabetic patients by means of doppler flow meter performed on the dorsalis pedis arteries & post. tibial arteries of the both lower limbs. Patients were divided into two groups, one with occlusion and the other without occlusion. Various predisposing factors causing peripheral vascular occlusions were examined. The results are summerized as follows: 1. Peripheral vascular occlusions were more prevalent in male than in female (male: 25.4%, female: 17.4%). 2. In male patients age, plasma cholesterol level & smoking were statically significant among the various predisposing factors between occlusion & nonocclusion groups. 3. In female patients, duration of diabetes mellitus and the sugar levels of fasting blood and post prandial 2 hours were statiscally significant.

The anterior cruciate ligament has been considered one of the basic stabilizers in the knee as a very complex in its function. A large number of treatment regimens and philosophies showed controversies in its treatment. And we have experienced recurrence of the instability after operation of the injured ligament. So, the authors devised a new operative technique for the loose anterior cruciate ligament, that is, distal davancement of the loose anterior cruciate ligament with a bone-block as a biomechanical fixation. We have performed 11 cases of the anterior cruciate ligament using distal advancement method. The results were as follows; 1. Eleven cases (92%) showed good results by the rating system of Cincinnati sports-medicine and Orthopaedic Center. 2. The distal advancement of the anterior cruciate ligament is technically simple and biomechanically reasonable, but further investigation is necessary to answer the question regarding the long term results.

Thirty-nine cases of tuberculosis of the knee were treated at the Department of Orthopaedic Surgery, National Medical Center during the 10 yesrs from Jsn. 1977 to Dec. 1986. The results were as followings 1) Total cases of tuberculosis of bone and joint were 411. Among them, knee joint occupied 39 cases (9.5%) 2) Age and sex distribution were not remarkable. 3) Average duration of disease were 27 months. 4) In 56.1% of the pstients, chemotherapy wss given prior to admission. 5) Tbe main associated tuberculosis lesions were pulmonsry tuberculosis (53.9%). 6) Erythrocyte sedimentation rate was increased in 61.6%. 7) The incidence of associated running draining sinus were 25.6%, and majority of the causative microorganisrn was Staphylococcus aureus in complicated mixed infection. 8) Various treatment, such as conservative, synovectomy, curettage, and arthrodesis, had been carried out. 9) Overall recurrence rate was 9.1%.
