1.Duchenne Type Muscular Dystrophy: Report of 8 Cases
The Journal of the Korean Orthopaedic Association 1970;5(3):149-153
Clinical review has been made for 8 cases of Duchenne muscular dystrophy admitted to orthopedic Department during the time between 1964 and 1969. Duchenne type muscular dystrophy, (Duchenne, 1849), is the most common type of the progressive muscular dystrophy. A number of reports have been found regarding its symptomatology, pathogenesis based on muscle biopsy, heredity and the change of serum enzyme such as aldolase, creatine kinase, and transaminase, though no definite treatment has been known. The results were as follows: 1) All eight cases were male of 5 to 13 years of age. 2) Gowers sign and waddling gait were noted in all cases and contracture in two cases. 3) Familial occurrence was noted in two (Case 1, 2). 4) Urinary creatine value was elevated in all cases, while creatinine excretio decreased in seven cases.

2.ULTRASTRUCTURAL INVESTIGATIONS OF THE INTERFACE BETWEEN CULTURED PERIODONTAL LIGAMENT CELLS AND TITANIUM.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 1997;23(4):668-672
A particular problem associated with osseointegrated implants is the fact that the implants lack a periodontal ligament. Thereby, marginal inflammation around an implant may cause more serious bone loss than does marginal inflammation around teeth with a periodontal ligament. In addition, osseointegrated implants are ankylosed and do not haute the same mobility as natural teeth with a periodontal ligament. Implants with a periodontal ligament would eliminate these problems. In order to explore the possibility of producing a periodontal ligament around titanium dental implants, a study of the attachment of cultured periodontal ligament cells to titanium was carried out. Periodontal ligament cells obtained from premolar teeth of individuals undergoing tooth extraction for orthodontic reasons were cultured on titanium-coated epon blocks. Sections of the blocks were cut perpendicular to the surface of the cell layer. Transmission electron microscopy of the periodntal ligament cells/titanium interface showed that there was no evidence of attachment at the cultured periodontal ligament cells titanium interface. The microfilaments, commonly located adjacent to the titanium surface, run mostly parallel to the titanium surface. The study showed that cultured periodontal ligament cells did not create an attachment structure on a titanium surface similar to that of natural teeth.

3.A Case Report of Traumatic Bilateral Bislocation of the Hip

The Journal of the Korean Orthopaedic Association 1971;6(1):79-82
Bilateral dislocation of the hip was observed in a 44-year-old man after the accident that he was overrun from backward by a slowly approaching goods-train. Successful manual reduction was obtained, followed by one month cast immobilization and partial weight bearing exercise thereafter. Peroneal palsy of right extremity, noted immediately after the dislocation, showed the prospect of good recovery. The mechanism of injury was also discussed.

The Journal of the Korean Orthopaedic Association 1977;12(3):539-541
The osteochondroma is a common benign tumor with osteocartilaginous exostosis. It may arise from any bone, but is observed most often on long tubular bones, particularly on their metaphyseal region. Osteochondroma may also arise from the rib but seldom grow to giant size. We experienced a rare case of giant osteochondroma arising from the left 5th rib. The patient, 41 years old man, had an adult fist sized mass on the left lower chest with mild aching pain on respiration. The large mass was examined by biopsy. It showed characteristic microscopic findings of osteochondroma. No evidence of malignant change was seen in this large tumor.

The Journal of the Korean Orthopaedic Association 1980;15(3):579-582
Congenital coxa vara is a rare congenital deformity, seen in infancy and childhood and the ratio of unilateral to bilateral is 3:1. The deformity does not become manifest until after birth and usually not until the age of walking. Pathologically, it consists of a progressively increasing acuteness of the neck-shaft angle;shortnees of the neck; a vertical direction of the epiphyseal plate; an oblique defect of the neck; a greater trochanter extending upward toward the ilium as a besk; a shortened femur; a secondary degenerative changese in the acetabulum due to malposition. We have experienced a case of bilateral congenital coxa vara treated with valgue osteotomy and the case review is presented.

BACKGROUND: The implementation of health care delivery system(HCDS) in 1989 affected the visit pattern of tertiary care hospital. In this study we analyzed the effect of implementation of HCDS in a university hospital. METHODS: We analyzed the yearbook of a university hospital from 1986 to 1992. The clinical departments were divided into three groups of medical departments, surgical departments with application of HCDS and clinical departments without application of HCDS. RESULTS: The total outpatient visits increased after implementation of HCDS. The new outpatient visits decreased after implementation in the medical departments and surgical departments but re-visit patients increased in all clinical departments. The number of emergent patients increased at year 1889, but decreased in 1990, then little changed. Admission rate via emergency room decreased in surgical departments and clinical departments without application of HCDS. The patient from Pusan in which hospital is located was little changed but patients that from other areas increased. So the proportion of patients from Pusan decreased, and from other regions increased. The visit of patients with self pay decreased, but patients with medical insurance increased. CONCLUSIONS: In spite of increased total outpatient visits, the new outpatient visits and patient visits from near place decreased through implementation of HCDS. The new outpatient visits decreased in the medical departments and surgical departments in clinical departments with application of HCDS, but the new outpatient visits increased in clinical departments without application of HCDS.
