1.A Study of Culture and Sensitivity Test of Mycobacterium Tuberculosis
The Journal of the Korean Orthopaedic Association 1977;12(4):681-684
A study of concentration smear, culture for AFB and sensitivity test for antituberculous drugs was carried out in 810 patients who had been admitted in SNUH in the period of 12 months from January 1976 to December 1976. Acid-fast bacilli was confirmed in 110 cases (13.6%) by concentrated direct smear and in 88 cases(10.9%) by culture, and concomitantly sensitivity test was performed in 26 isolated cases. Streptomycin, INH, PAS, Kanamycin and Ethionamide were rather less sensitive to the strains of Mycobacterium tuberculosis, but all strains obtained during the period of this study were highly sensitive to Rifampicin.

2.The Effect of Intramedullary Vascular Bundle Implantation in the Femoral Canal
The Journal of the Korean Orthopaedic Association 1987;22(2):339-348
Tureta and his colleagues have stressed the important role that vessels play in osteogenesis. Numerous arthors attempted to provide new bone formation by placing vascular pedicles into the bone. Some reports are convining, but experimental model and histological investigation leave something yet to learn. We conducted an experiment to demonstrate the feasibility of using a vascular bundle to create new bone formation in medullary canal. Vasculsr bundle of the femoral artery and vein was transplanted in same side of the femoral canal of rabbits. The transplanted vascular bundle was studied histologically for eight weeks. At 3 weeks transplanted artery started proliferation of intima and media, and its lumen was obliterated completely at 6 weeks. Transplanted vein collapsed from begining, and didn't involve in revascularization and new bone formation. At 2 weeks the proliferation of capillaries promoting revascularization originated from the adventitia of the transplanted artery, and peaked at 6 weeks. New osteoid appeared around the transplanted vessel at 2 weeks, and surrounded the entire vessel in 5 weeks, and had no more progression in amount at 6 weeks. Cortical hypertrophies showed in the vascular bundle transplanted group from 3 weeks. Examination of control group revealed no sign of new osteoid formation around the hole during the whole study period.

Desmoid tumor is a type of fibromatosis usually arise in deep musculo-aponeurotic structures, primarily of the trunk and extremities. It is characterized by proliferation of fibroblastic tissue and does not metastasize but may be locally aggressive. Eventhough the surgical margin reveals clean, recurrence often occurs. To analyze the extent of the tumor and homodynamic characteristics exactly, we performed IV bolus CT. Desmoid tumors show peripheral rim enhancement on early phase scan and more strong, central enhancement on late phase IV bolus CT, which reflects abundant fibroblastic components of the tumor. We report two cases of pathologically confirmed desmoid tumor performed IV bolus CT.

To investigate the heterogeneity of fibroblast proliferation rate depending on the depth of dermis in the psoriatic skin lesions, fibroblasts were obtained from the upper and lower dermis of the forearm skin lesions in 9 psoriatir, patients and of the comparable sites in 7 healthy persons respectively, and were cultured. The in vitro proliferation rates of the fibroblasts were calculated by measuring the efficiency af cell attachment, cell numbers on varying days of culture and the population doubling time during the 3rd passage of subculture. The results were as follows: 1, The efficiencies of cell attachment at 24 hours after seeding were not statistically different between the upper derrnal fibroblasts and the lower ones in both psoriatic skin lesions and normal skins. 2. By rneasuring the cell numbers and the population doubling times, the prolifeatior rate of the upper der mal fibroblasts was greater than that of the lower ones in both psoriatic skin lesions and normal skins and that the fibroblastic proliferation rate was significantly inereased in the psoriatic skin lesion compared to the normal skin.

6.Triple Osteotomy of the Innominate Bone: Experlence with an adult Paralytie Hip

In the treatment of dislocations and subluxations of the hip in the older children, whether congenital or paralytic, orthopedic surgeons are blessed with a wide variety of commonly used surgical procedures; namely, Salters innominate osteotomy, acetabtloplasties, Pembertons pericapsular osteotomy, shelf operations, Chiaris pelvic displacement osteotomy. and Colonnas capsular arthroplasty. However, with increasing age and soft tissue contractures,these procedures become ineffective, leaving a wide range of age between older children and young adults subject to uncertain or unfavarable prognosis. Steels triple osteotomy (1973) is aimed at coverig this age group, when displacement or in nominate osteotomy is either technically infeasible or likely to fail. It consists of an open reduction with or without soft tissue release and skeletal traction, redirection of the acetabulum to cover the femoral head by osteotonmies of the pelvis that has lost its young cartilagenous resiliency, and preservation and physiological remodelling of the articular cartilage of the acetabulum. We performed Steels osteotomy on a 21-years-old female with a severe paralytic subluxation of the hip associated with pelvic obliquity and paralytized both lower extremities. One and a half year follow-up result was satisfactory with a stable and congruous joint despite paralysis and with the patient walking for the first time in her life.

Clinical observation of thirty-eight cases of pyogenic osteomyelitis of the spine for the period of eleven years, from 1965, at Seoul National University Hospital was carried out with the following results. 1. The incidence of pyogenic osteomyelitis of the spine among total cases of the pyogenic osteomyelitis was 6.9% and the ratio between the spine tuberculosis and the pyogenic osteomyelitis of the spine was 1:0.067. 2. The sex ratio between male and female wss 3.8: 1 The incidence was higher ia the second and third decade and the average prevalent age was 30.8 years of age. 3. The site of infection was in the lumbar vertebrae in 25 cases(66%), thoracic in seven(19%), lumbosacral in three, sacral in two and cervical in one. In the region of a vertebra, the vertebral body was affected in 33 cases (87%) and the neural arch and processes in other 5 cases (13%) 4. The causative micro-organism was isolated in 27 cases from the diseased focus; coagulase positive staphylococcus in 18 cases (67%), streptococcus in one, salmonella in one and the mixed infection in two. 5. Frequent clinical symptoms and signs were back pain, tenderness, muscle spasm, fever and chillness, and limited motion of the spine. 6. The roetgenographic findings were in order of disc space narrowing, destruction of the vertebral body, kyphosis or loss of lordosis, erosion, bony bridging or spur formation, sclerosis and paravertebral abscess. 7. The conservative treatment was performed in 14 cases. Among 7 cases in which the follow-up was possible, only 3 cases obtained the satisfactory result, four cases were readmitted for the recurrence and two cases among them needed the operative treatment later. The operative treatment was peformed in 26 cases; The focal curettage with anterior interbody fusion through anterior approach was carried out in 13 cases with the satisfactory result in almost all cases. 8. The advantages of the operative treatment were that the isolation of the offending organism was efficient and the definite diagnosis was feasible, and especially in cases of anterior spinal fusion the healing and union of the infected spine was better clinically and roetgenographically in comparision with those of conservative treatment, in which the expected spontaneous fusion was not found in any case and the recurrence was also frequent.

Rickets is a syndrome, characterised pathophysiologically by a failure of normal mineralization of bone and epiphyseal cartilage and clinically by skeletal deformity in growing children. The four principal causes of rickets are; vitamin D deficency, renal tubular insufficiency, chronic renal insufficiency, and hypophosphatasia. Of these, vitamin D resistant rickets may result from primary defect in function of the renal tubular reabsorption for phosphorus, later accompsnied with secondary hyperparathyroidism. We experiened a rare case of hypophosphstemic vitamin D resistant rickets accompanied with secondary hyperparathyroidism in adolescence.
