Supracondylar osteotomy was performed on 78 knees in 65 patients with poliomyelitis for correction of deformities of the knee at the Department of Orthopedic Surgery, Seoui National Unlversity Hospital, during the 16 years from January 1963 to December 1978. Following observations were made from the review of statistics, technical problems, and complications of the operation. 1. The ages of the patients ranged from 4 years to 28 years, the average being 15 years. Two thirds of the patients were in the second decade. 2. 37 knees (47.4%) had flexion deformity, 19 knees (24.4%) flexion-valgus deformity, and 13 knees (16.7%) flexion-valgus-external rotation deformity. The amount of flexion deformity ranged from 7 degrees to 90 degrees, the average being 22 degrees. Valgus deformity ranged from 3 degrees to 25 degrees, the average being 12 degrees. External rotation deformity ranged from 5 degrees to 30 degrees, the average being 18 degrees. 3. The operative techniques employed were categorized into 5 types. The most common type was a closed wedge hinged osteotomy (Technique I), which was employed on 50 knees (64.1%). Satisfactory results were obtained by combining other procedures, when necessary, i.e. pre-operative skeletal traction, Yount fasciotomy, high tibial rotation osteotomy hamstring transfer and epiphysiodesis. 4. The time required for union was the shortests in the Technique 1 group, and longest in the Technique III group, a complete osteotomy with bone shortening. 5. The most common complication was stiff knee, which was encountered in 10 knees. Residual or recurrent deformity was observed in 4 knees, in 3 of which hamstring transfer was recommended but was not consumated. Delayed union was observed in 3 knees in the Technique II group (closed wedge complete osteotomy) and in 1 knee in the Technique III group. Nonunion occured in 1 knee in the Technique II group. The incidence of complications were higher in the Technique II and III groups, and lowest in the Technique I group.

PURPOSE: It has been known for a long time that infants of insulin dependent diabetic mothers are prone to develop macrosornia, organomegaly, hyperbilirubinemia, respiratory distress syndrome, hypoglycemia, hypocalcemia, septicemia and congenital anomalies in the neonatal period. And echocardiographic asymmetrical- ventricular septal hyper- trophy(ASH) has been observed in the newborn infants of diabetic mothers. The etiology of the ASH remains unknown, although fetal hyperglycemia and subsequent glycogen deposits have been postulated as contributing factors. Therefore, we have studied whether large for gestational age(LGA) has played an important role of developing ASH. METHODS: We compared echocardiographic findings in neonates of LGA and appro- priate for gestational age(AGA), who were admitted to the Department of Pediatrics, Chung Ang University Hospital from April 1994 to March 1997. RESULTS: 1) Mean LVED in LGA and AGA were 1.96+0.06cm and 1.94+0.04cm, respectively. 2) Mean LVPW in LGA and AGA were 0.37+0.05cm and 0.370.05cm, respectively. 3) Mean IVS in LGA and AGA were 0.400.09cm and 0.380.09cm, respectively. 4) Mean IVS/ LVPW in LGA and AGA were 1.09+0.12 and 1.040.17, respectively. There was no statistical significance between two groups in echocardiographic findings. CONCLUSION: There is no relation between LGA and ASH in the neonate. According- ly, we may not need to perform echocardiography LGA routinely.

Bone is a heterogenous and anisotrophic material exhibiting elastic, viscoelastis and plasticproperties. A considerable amount of information is now available regarding biomechanical properties and mechanisms of fractures of mature long bones, but less is known about the properties of the growing bones. In order to assess the biomechanical properties under tension, rabbits growing bones were loaded with Instron Modal 1,000 until fracture occurred. Two hundred tibiae of 100 New Zealand white immature rabbits were divided into 6 experimental groups according to maturity and size. Group I-R(40 right tibiae of 1-month old rabbits), Group I-L (40 left tibiae of 1-month old rabbits), Group II-R(20 right tibiae of 3-month old rabbits), Group II-L (20 left tibiae of 3-month old rabbits), Group III-R(40 rigth tibiae of 5-month old rabbits), and Group III-L(40 left tibiae of 5-month old rabbits). The following results were obtained. 1. Fracture type was transverse.or nearly transverse in 170 out of the total 200 tibiae(85%).
