In femorsl neck fracture, viability of the femoral head depends on the revascularization of the femoral head. The purpose of this study is to observe the effect of early fixation and anatomical reduction by measuring the Tc-99m-MDP uptake ratio of the femoral head in experimental animsls. Femoral neck region of 20 mature rabbits were osteotomized completely and divided into 2 groups ; each group consisted of 10 rsbbits. Group 1 had two Kirschner wire fixation after osteotomy and anatomic reduction. Group 2 had no fixation after osteotomy. The uptake ratio of Tc-99m-MDP of the femoral head in each group were measured st the intervals of 24 hours, 48 hours, 1 week, 2 weeks, 3 weeks, and 4 weeks, respectively. The results obtained were as follows ; 1. In experimental group 1, the mean uptake ratio of the femoral head was 0.72±0.13 at 1 day after operation, increased to a level of 1.44±0.14 at 1 week, increased to a maximal value of 2. 90±0.36 at 3 weeks and decreased to a level of 1.10+0.12 at 4 weeks. 2. In experimental group 2, the mean uptake ratio of the femoral head was 0.70±0.10 at 1 day, 0.64±0.13 at 1 week, decreased to a maximal value of 0.33±0.05 at 3 weeks and 0.47±0.05 at 4 weeks, showing decreased level below 1.0. The results suggest that early anatomicsl reduction and rigid fixation of femoral neck fracture is helpful for revascularization of the femoral head and prevention of non union.

Deformities of the leg and ankle may result from growth abnormalities of the tibia and fibula. The appearance of the secondary ossification center and growth plate closure of the tibial and fibular epiphyses, and the pattern of closure of the epiphyses, were observed in a different age. Normal radiographs were reviewed in one hundred and fifty patients at age from two days after birth to 20 years, who were injured on the contralateral leg, at Wonju Medical College, Yonsei University from Feb., 1980 to May, 1984. The results were as follows: 1. The time of the appearance of secondary ossification center and the closure of growth plates; The proximal tibial epiphysis usually forms secondary ossification center at birth to second postnatal months, the physeal closure occurs from 13 year and 11 months to 18 year 3 months in male, from 13 year 4 months to 15 year 5 months in female. The secondary ossification center of the distal tibial epiphysis appears from 8th postnatal months to one year, and physeal closure occurs from 15 years to 17 year and 4 months in male, from 15 year 2 months to 16 year 8 months in female. The secondary ossification center of the tibial tuberosity appears from 9 year 3month to 12 year 2 months, and closure occurs from 16 year 3 months to 18 year 7 months inmale, from 14 year 10 months to 19 year 1 months in female. The proximal fibular epiphysis forms secondary ossification center from 2 year 5 months to 5 year 4 months, closure occurs from 15year 8 months to 17 year 4 months in male, from 14 year 9 months to 16 year 9 months in female. The secondary ossification center of the distal fibular epiphysis appears from 2 year 5 months to 3rd years, and closure occurs from 13 year 11 months to 17 year 6 months in male, from 13 year 4 months to 16 year 7 months in female. 2. The growth and the pattern of the closure of growth plates of the tibia; The proximal tibial epiphysis is elliptic for the first 3 years of life. The epiphysis is slightly conical centrally as it extends toward the tibial spines, and becomes more prominent from 8 years to adolescence. The closure of the proximal tibial growth plate occurs initially along the anteromedial aspect of the tibia and tibial tuberosity during 12 years and proceeds posterolaterally. Complete closure of the proximal tibial physis occurs about from 13 years to 18 years. The secondary ossification center of the distal tibial epiphysis is oval in shape initially, becomes thicken medially by 3rd year of life, then the tibial plafond is valgoid, and becomes horizontal at age 10 approximately. The distal epiphysis of tibia unites first at about 13 years, starting centrally and proceeding toward anteromedial portion. And the posterolateral portion unites finally by about 15 to 17 years. The tibial tuberosity develops a secondary ossification center by 7 to 9 years, usually in the most distal region, and gradually elongates and extends toward the secondary ossification center of the proximal tibia.From about 12 years, the tuberosity epiphyseal center fuses with the proximal tibial center, and the fusion with the tibial metaphysis extends distally, the tuberosity physis closes completely from about 15 to 19 years. 3. The growth and development of the tibia, fibula and ankle; The growth of the proximal tibial and the distal fibular epiphyses play an important role of the growth rate in lower extremities unber ten years. The distal tibial growth plate inclines laterally and distally prior to the first year of life, the inclination is on the decrease and it finally horizontal at about 12 years. The distal tibia talus angle is about 90° prior to the age one year, becomes mildly valgoid by 12 years.

7.A Survey on the Perceptions of Guardians of Pediatric Oculoplastic Patients.
Journal of the Korean Ophthalmological Society 2007;48(8):1023-1027
PURPOSE: This survey was performed to gather information about the guardians of pediatric oculoplastic patients undergoing certain medical care services in order to recommend improvements in these services. METHODS: Questionnaires were distributed to guardians of pediatric oculoplastic patients who were admitted for operations to correct epiblepharon and ptosis. Completed questionnaires, which numberd 100, were then analyzed. RESULTS: The results of this survey show that most guardians were the parents of the patient; most had a level of education higher than or equal to junior college graduation; and most were middle-class. The parents themselves had discovered their children's disease and had a great influence on the decision to operate. Most parents took an optimistic view of the results of the operation. The higher the guardians' economic status, the more likely he or she believed that both an ophthalmic and a plastic surgeon could perform oculoplastic operations. Many guardians chose an ophthalmic clinic over a plastic surgery clinic because the likelihood of a satisfactory result is higher and because these diseases are related to visual acuity. Half of the guardians knew that there is an oculoplastic clinic at the department of ophthalmology, and many of them gathered information about oculoplastic surgery from the internet. CONCLUSIONS: Better explanations about oculoplastic diseases and more education about these diseases should be available to the guardians of patients with these diseases. Systematic publicity for the field of oculoplastic surgery is needed urgently, and the availability of accurate information and specialized medical counseling about these diseases on the internet should be increased.

The Clufoot is still controversial in the etiology, the pathology, and the method of the treatment. Turco issued one stage posteromedial soft tissue release in 1971, which is still widely used. But the Turco's procedure is not satisfactory results in forefoot adduction and ankle motion. McKay and Simon were performed one stage complete subtalar soft tissue release and reported better results compared with those who had posteromedial release. So we performed Turco's posteromedial release with lateral release by Cincinnati incision in 12 patients (20 feet) and analysis the results from Oct. 1987 to Jul. 1989 at the department of orthopaedic surgery of CNUH. The results were as followings ; 1. The mean age of the patient at first examination was 1 year 9 months (range from at birth to 5 year 10 months) and the mean age at operation was 2 year 1 month (range from 4 months to 5 year 10 months). 2. The clinical results were excellent in 2 feet, good in 14 feet, fair in 3 feet and unsatisfactory in 1 foot. 3. The radiological results were satisfactory in 18 feet and unsatisfactory in 2 feet. 4. Forefoot adduction was corrected in 14 feet (70%) as normal range, 3 feet as acceptable, and 3 feet as unacceptable 10' over the normal range. 5. Two feet of hind foot overcorrection result was operation as McKay's method. 6. The Clincinnati incision was favorable to visulization and release of the posteromedial, anteromedial and posterolateral structure of the foot.
