Antibiotic-acrylic bone cement composites demonstrated antibacterial activity as a result of diffusion of antibiotic from bone cement into surrounding enviroment, accordingly, the use of antibiotic incorporation to bone cement for the prevention and treatment of infection after joint surgery replacement has been adovocated. Early report of clinical success by using antibiotic-acrylic bone cement composites are encouraging. Our authors applied this concept to the treatment of chronic osteomyelitis. Antibiotic contained with bone cement was chosen by sensitivity test on pus culture finding. Seven cases of chronic osteomyelitia treated by using antibiotic-acrylic bone eement composites were .studied in the Department of Orthopaedic Surgery, Kyung Hee University Hospital from July 1979 to March 1981. The follow-up period was from 3 months tc 22 months. The results were as follow: 1. Six cases showed no evidence of recurrence except one by using antibiotic acrylic bone cement composites. 2. The impregantion of antibiotic in acrylic bone cement shall be regarded to be effective in increasing the local antibacterial activity by leaching the antibiotic into surrounding tissue over a period continiously in treatment of chronic osteomyelitis. 3. The use of antibiotic-acrylic bone cement compositea into dead space by saucerization are consid- ered an one such approach to the decrease of dead space. 4. The impregnation of antibiotic in acrylic bone cement is regarded a new concept in treatment of chronic osteomyelitis.

Lichen scrofulosorum, also known as Tuberculosis cutis lichenoides, is thought as a tuberculid such as Erythema induratum, Papulonecrotic tuberculid, Tuberculosis miliaris disseminata and Lupus miliaris disseminatus faciei. The lesions of Lichen scrofulosorum are pin-head sized or smaller, normal skin or reddish brown colored, arranged in nummular groups, usually on the trunk, where they persist unchanged or undergo spontaneous involution. As a rule, they appear in children who have tuberculosis of the bones or the lymphnodes. We report a case of Lichen scrofulosorum, 13-year old girl, who showed clinically and histologically typical lesions on the trunk. She was highly sensitive to Mantoux test and had tuberculous lymphadenitis of left cervical lymphnodes, but the chest was negative. Many challenges to the tuberculous origin of the tuberculids including Lichen scrofulosorum have prevailed for the last decade, Several studies and reports indicated that healing responses of Erythema induratum and other tuberculids to corticosteroids were more definite than to anti-tuberculosis drugs. But more recently, some reports recommended that anti-tuberculosis drugs were eftective than corticosteroids (in the treatment of Erythema induratum and other tuberculids). In this case anti-tuberculosis treatment with PAS 10gm., INH 400 mg., and streptomycin 1.0 gm. daily for the first one month and then 1.0gm. twice a week has remarkably improved the clinical manifestation in follow-up of three months. While the follow-up period was no enough, we strongly suggest the tuberculous origin of Lichen scrofulosorum.

5.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.

6.Serum Osteocalcin Measurement by RIA in Bone Diseases Associated with Osteoporosis and Metastatic Cancer
The Journal of the Korean Orthopaedic Association 1988;23(2):600-610
Controversy persists regarding the abnormality of the bone metabolism in various bone diseases. Osteocalcin, the vitamin K-dependent protein synthesized in bone, has been shown to be a specific and sensitive marker of bone turnover in metabolic bone diseases. The author measured the serum osteocalcin level using newly developed radioimmunoassay (RIA) in the patients with osteogenesis imperfecta, metastatic bone tumor, postmenopausal osteoporosis and rheumatoid arthritis, which can be the causes of osteoporosis, and ankylosing spondylitis. The aim of this paper is to demonstrate the value of the osteocalcin measurement comparing the each data of disease group with the normal control group. The results were as followings ; 1. The mean of osteocalcin in normal Korean was 4.43±1.04 ng/ml. (4.45±1.08 ng/ml in male, 4.41±1.01 ng/ml in female). The difference between male and female was not significant statistically. 2. The osteocalcin of osteogenesis imperfects was 9.14±2.21 ng/ml, which was significant statistically, And it was thought to be the result of increasing bone turnover rate and the osteocalcin was useful as biochemical marker. 3. In metastatic bone tumor, osteocalcin was under the normal level in both untreated and treated groups, which meant low bone turnover rate or low osteoblastic activity. Osteocalcin was not a useful marker for the assessment of the effect of treatment in this study, but if the radioimmunoassay was done in the same tumor group, a valuable results could be expected. 4. Osteocalcin level in the patients with postmenopausal osteoporosis and rheumatoid arthritis was not different with normal control group and osteocalcin was not useful marker for the evaluation of the degree of osteoporosis and bone turnover. 5. Osteocalcin didn't play a role in the pathologic ossification of ankylosing spondylitis. In conclusion, the osteocalcin by radioimmunoassay can be used as a biochemical marker in metabolic bone diseases and metastatic cancer for the disgnosis and the assessment of prognosis or the effect of treatment.

Tuberculosis of the spine still remains an as important problems in Korea, There is much controversy over the advantage of indication for surgical versus medical treatment, and the correct answer probably lies between the two extremes. Recently focal debridement is widely accepted operation method, andmany reports dealing with this subject have been published. Because of limited vacancy of the hospital and poor economy, a large group of patient with tuberculous lesion in spine have been treated conservatively with anti tuberculous medication and aspiration of abscess and immobilization by plaster shell etc. Authors than attempted a clinical analysis on a patient-group (40cases) treated at Pusan University hospital and Pusan Children Charity hospital, and obtained the results as follows: 1. The kyphosis of the spine tends to be aggrevated with collapse of vertebra. 2. Kyphosis aggrevated in 67.5% of cases: 18.7 degree of increase in whom plaster jacket was additionally applied, while 27.5 degree of increase in the cases without plaster. Time of aggrevation of kyphosis after institution of treatment was variable as 3 to 18 months. 3. Pathological reflexes were found in 16 cases, which were disappeared in 18 months after the treatment. 4. Psoas abscess was completely absorbed in 3 rd to 9 th month after treatment by repeated aspiration with one month interval. 5. Regression of paravetebral abscess shadow on the X-ray film was observed very slowly from 2 nd month to 30 th month, mainly disppeared in 6 th month after conservative treatment. 6. Thirty four cases had back muscle spasm, paraparesis in the lower extremity with difficulty of walking, and recovered within 15 months with complete relief of back muscle spasm.

The Journal of the Korean Orthopaedic Association 1970;5(4):201-205
We experience still a number of cases of residual polipmyelitis with severe deformities which have not been treated for more than 10 years in Korea. During the period of January to August in 1970, 40 cases of residual poliomyelitis had corrective operations performed at Department of Orthopedic Surgery, Pusan National University Hospital. Among those Two cases showed extreme deformities of hips and knees, having not been treated at all for past 18 years. There were flexion contractures of hips 50/80(Rt/Lt) and knees 90/90 in case 1 and flextion contractures of hips 75/90 and knees 80/100 in case 2. Various controversial methods of surgical treatment have been described since 1914 when Soutter introduced a procedure for flexion contracture. In case 1 the procedures of Soutter and Yount, division of the hamstring tendons and posterior capsulotomy of knee were performed by the authors. The bilateral contractures were not corrected completely and the residual deformities remained. In case 2 a compelet correction was obtained by release of iliopsoas insertion and supracondylar osteotomy combined with the operations done in case 1. From this clinical observation the authors reached to the conclusion that the release of insertion of iliopsoas muscle and supracondylar osteotomy are the essential procedures for correction of flexion contracture of hip and knee.

This experiment was performed to determine the stability of antiblotics in cured bone cement and the antibacterial effect with various the amount of antibiotics mixed in bone cement. Experimental animals were divided into control and antibioticimpregnated groups; 3 each for control, cloxacillin, celospor, kanamycln and panimycln groups. Antibiotic activities were measured by disk diffusion method using Staphylococcus aureus and Escherichla coli as standard organisms. The results were as follows: 1. Bone cement itself does not have antibacterial effect on the growth of Staphylococcus aureus and Escherlchia coli. Antlbiotlc impregnated acrylic bone cement showed antibacterial effects which was stable for 4 weeks. 2. In vitro test, the amount to antibiotics released In 24 hours perlod was proportional to the amount of antibiotlcs mixed in bone cement. 3. The duration of antibacterial effect was also roughly proportional to the amount of antiblotics mixed In bone cement. 4. No antibacterial effect could be measured in control groups. 4. In vivo test, the result was revealed similar patterns compared with the result of “In vitro test”, but the amounts of antibiotics released and durations of antibaterial effect was decreased. No antibacterial effect could be measured in control groups. As a result of this sutdy of this study, It is proved that the amount of antiblotics and the duratlon of antibacterial effect are proportional to the amount of antibiotics mixed in bone cemcnt. The impregnation of antiblotics in acrylic bone cement may be used to prevent and treat Infection in the orthopedic fleld.
