The Journal of the Korean Orthopaedic Association 1978;13(4):679-692
Of 43 scoliotic patients treated by Harrington instrumentation and posterior spinal fusion, 38 patients were taken of preoperstive correction by Risser localizer cast, turn buckle cast. Cotrel traction or halofemoral traction from April 1969 to June 1978 at the Department of Orthopaedic Surgery, Seoul National University Hospital. The correctaibility of scoliosis by preoperative correction were evaluated with its methods, etiology, age, severity of the curve and curve pattern. and following results were obtained: 1. Age distribution was from 8 years to 39 yeara of age and mean age was 17. 2 years. 2. The etiology of the 43 cases was idiopathic in 15 (34.9%), paralytic in 10(23.3%). congenital in 9 (20.9%), neurofibromatosis in 5(11.6%) and others in 4, 3. The most common curve pattern was thoracic curve in 20 cases (40. 8%), and thoraco-lumber curve in 13, lumbar curve in 9, double curve in 5. 4. The average initial curve was 80.7 degrees with the flexibility of 36.9% on side bending; preoperative correction 31.3 degrees (38.3%) and immediate postoperative correction 40.6 degrees (50.3%). 5. As preoperative correction, Risser localizer cast was applied in 23 cases (53.5%) with 28.8 degrees (37.4%) of correction, turn buckle cast in 1 case with 80. 0 degrees (54.1%) Cotrel traction in 5 case with 27.5 degrees (40.7%) and halofemoral traction in 9 cases with 36.9 degrees (38.2%). 6. The best correction was obtained in idiopathic type and then followed with paralytic and congenital type. 7. Halofemoral traction was effectively applied in cases of rigidand severe, curve, mostly in older patients; the initial curve 96.5 degrees with 28.5% of flexibility. 8. The best correction was obtained in thoracic curve (39%) and then followed with thoracolumbar and lumbar curve. Halofemoral traction was effectively applied in tho racic curve. 9. Duration of preoperative correction was 5.1 days in Risser localizer cast, 7 days in turn buckle cast, 6.4 days in Cotrel traction and 13.3 days in halofemoral traction. 10. Most of preoperative correction were obtained in a few days of traction; 92% in half week with Cotrel traction and 83% in half week and 91% in one week with halofemoral traction.

Metaphyseal Chondrodysplasia is a disease characterized by metaphyseal ossification leading to shortening of stature. The extremities, especially lower, and mainly affected, resulting in a disproportionate drarfing which spares the trunk. The first case was reported in a patient with irregular metaphysis of lower extremities and hands, and severe shorteness of stature by Murk Jansen in 1934. A milder form of Metaphyseal Chondrodysplasia was noted in 1949 by Schmid, which is more common and transmitted in autosomal dominant. Mckusick recently reported another form of Metaphseal Chondrodysplasia, and other types were reported, but they are extremly rare, and of little clinical significance. In the Schmid type, patient is normal at birth, but characteristically shortness of stature, bowed leg, and waddling gait developed at biginning of walking. Ali labratory findings including serum calcium level, phosphorous, alkaline phosphatase, renal function test is normal in Metaphyseal Chondrodysplasia. The most difficult differential diagnosis is Vitamin D-resistant rickets in clinical and x-ray findings. The only treatment is careful observation and properly timed corrective surgery. Authors experienced on case of Schmid type of Metaphyseal Chondrodysplasia which had been treated with Vitamin D under impression of rickets for 1 year before the case was consulted to Orthopedic Department. Proximal tibial osteotomy and subtrochanteric valgus osteotomy were performed for the correction of genu varum and coxa vara deformity with satisfactory results for one year follow up.

Articular cartilage can be damaged by trauma or by progressive degradation caused by disease. Unfortunately, it has a extremely limited capacity for repair and regeneration. The use of joint prosthesis has revolutionized but remains limited in its use. To know the possibility of clinical application of clinical application of autogenous bone-articular graft in open complicated intraarticular fractures we studied the change of bone-articular cartilage defect in medial femoral condyle of rabbits and viability of autogenous bone-articular graft stored within abdominal wall of rabbits. The results were obtained as follows: 1. There was over 90% viability of subchondral bone after 10 days storage in the adbominal wall but the articular cartilage showed degenerative change about 40% after 5 days passed. 2. The bone-articular defect was replaced by undifferentiated mesenchymal tissue and fibrous tissue, postoperative 6 weeks later. 3. In implanted bone-articular cartilage graft at 3 days, the chondrocyte of basal cell layer in articular cartilage was relatively well preserved but in 7 days, transplanted articular cartilage graft showed almost necrotic chage. Most of subchondral bones were well healed with host bone without regard to duration of implantation.

Apert described acrocephalosyndactyly as a clinical entity in 1906. At first he included a patient with craniofacial deformities combined with syndactyly of both the upper and lower extremities. This is a rare congenital disturbance in the growth of bone and soft tissue affecting principally the head, the hands and the feet. More than 200 cases have been reported in the world literature, and three cases in Korea. Authors experienced one case of the classic pattern of Apert's syndrome and treated surgically for syndsctyly.

Most orthopedic surgeons were aimed at the rigid internal fixation on the surgical treatment of the fracture. And the compression plate was developed and regarded as an excellent rigid internal fixation device by its advantages of accurate anatomical reduction, early joint mobilization and shortening of the duration of the fracture healing, which are chief aim of A.S.I.F. method. During the period of January 1970 to December 1979, 67 cases of diaphyseal fractures of the long bones were treated with compression plate according to A.S.I.F. method at the Department of Orthopedic Surgery, College of Medicine, Seoul National University and results were obtained as follows: 1. The age of patient was ranged from 15 to 77, and the highest incidence was in the 3rd decade male group (31.4%). 2. Old fracture cases were slightly more than fresh cases, and the fresh femur fracture was the commonest. 3. The periods of the postop immobilization of fresh fractures were 3.7 weeks in humerun fracture, 6.3 weeks in forearm fractures, 8.7 weeks in femur fracture and 7.0 week in tibia fracture, and in old fractures about 4 weeks was longer than fresh fractures. 4. The bony union was accomplished in all cases between 8 week and 24 week. 5. The complication were 4 superficial infections, 4 deep infections, 1 delayed union and 9 joint stiffnesses. 6. Compression plate fixation is considered as an excellent method for the treatment of the fractures of the long bones.

The ankle joint is a modified complex hinge joint which plays an important role in weight bearing, walking and standing. Injuries about the ankle joint cause destruction of not only bony architecture but often also the ligamentous and soft tissue component. So the goal of the treatment of ankle fracture is restoring normal relations of ankle mortise and regaining a smooth articular surface. The author have reviewed 84 cases of ankle fractures which were treated through the admission in the Orthopedic Department, In Je Medical College Pusan Paik Hospital from June 1979 to August 1986. The average duration of the follow-up was one year. The results obtained from this study were as follows : 1. The most common type was Danis-Weber type C. Nexts were B and A in order. According to the classification of Lauge-Hansen, the most common type was Pronation-external rotstion(39.2%). 2. In Danis-Weber type B and C, satisfactory result was obtained by operative treatment. 3. Danis-Weber's classification was very practical criteria for treatment of the ankle fracture.

Most obviuos will be the several anatomic differences between the proximal femur of the child and the adult. Fractures of the femoral neck in the children are extremely rsre and usually are the result of severe trauma in 80% of the cases. This accounts for the high frequency of serious associated injuries. In this injury the vascular anatomy changing with age, continuing growth potential and the effect of deforming forces play critical roles in high complication rate and these make treatment difficult. But still any secure guidelines for the treatment of this injury are not established and this is a field which requires more active research and further progress in future. 26 cases treated at Paik Hospital from Jan. 1979 to June 1988 were analyzed in clinical and radiological aspect and the following results were obtained. 1. The commonest type was Cervicotrochanteric fracture in 13 cases(50%),displaced one 21 cases. 2. In Transepiphyseal, Transcervical and Cervicotrochanteric fracture by early reduction and internal fixation, and in Intertrochanteric fracture by conservative treatment we gained satisfactory results. 3. We experienced 2 cases of coxa vara in nonthreaded pin used cases, 4 cases of premature epiphseal closure and 4 cases of avascular necrosis in threaded pin used ones. 4. Complications were developed in 13 cases (50%). These were 5 cases of coxa vara(19.2%) 4 cases of premature epiphyseal closure (15.4%) and 4 cases of avascul necrosis (15.4%). 5. Avascykar necrosis was developed in displaced fracture of Transcervical or Cervico- trochanteric fracture beyond postoperative 1 year. So. we recommend periodic long follow up for evaluation of avascular necrosis.

BACKGROUND: Oncogenes and EGF-Receptor(EGFR) may be involved n different stages of the multistep carcinogenesis process. A specific pattern of karyotypic abnormalities in solid tumors can be detected by cytogenetic methods. OBJECTIVE: This study is intnded to observe the cytomolecular kiologic chracterization of c-myc, erb B and EGFR genes in squasnous cell carcinoma(SCC) of the skin and cervix. METHODS: We have eytogenet,ically examined the short-term culturs from SCC. The rearrangement, amplification or expressi.on of erb B, c-myc, and EGFR genes were studied by Southern blot, analysis of genomic DNA and by slot blot analysis of tota! RNA extracted from biopsies of normal skin and SCC tissues. EGFR expression was examined immunohistochemially using monoclonal antibodies and the localizat,ion of the c-myc oncogene mRNA by in situ hybridization. RESULTS: A remarkably structural aberration was del 6(q21-qter) counted 20 metaphases among 28 metaphases ana1yzed. In nunierical aberration, all chromosomes were lost or gained randomly. Amenploid including triploid and tetraploid were observed in 8 metaphases, 6 tumor cells contained marker chromosome. In Southern blot analysis, rearrangement and amglificaton of EGFR in primary squamous cell carcinoma of cervix uteri and skin respectively. In slot blot analysis, the levels of c-myc, erb B and EGFR mRNA increaaed respectively 3.5, 2.5 and 2.8 times in SCC when compared to normal tissues. In immunoperoxidase stain, EGFR was present, in SCC where keratinocytes with strong cyto-plasmic staining but no membr, line labelling, where as in normal skin the were primarily present in t,he membrane and cytoplasm of basal cells. In situ hybridization with c-myc cDNAs allowed detection of grains representative of biotin labelled cDNA-mRNA hybrids in the frozden section of SCC tissues. CONCLUSION: These results suggest that specific patterns of karyotypir abnormalites, rearrangement, or amplification of EGFR gene, and overexpression of oncogenes and EGFR gene may be associated with the carcinogenesis of SCC.
