30 cases of distal femur fracture were treated with cast-brace for 2 years and 6 months from Feb., 1977 till July, 1979 at the department of Orthopaedic Surgery, Presbyterian Medical Center, in Jeon Ju. The results were obtained as follows: 1. In 9 cases, cast-brace were applied initially and other 21 cases were treated with cast-brace secondarily after operation. 2. 20 cases were male and 10 cases were female. 3. 12 cases were on mid 1/3 fracture and 18 cases were distal 1/3 fracture involving 2 condylar fractures. 4. The average duration of fracture healing was 14.7 weeks in the cases with cast-brace which is compared with 20.7 weeks of hip-spica cast control group. 5. A.G.F. of knee joint was 80–115 degree at removal of cast-brace, otherwise merely 50–65 degree at dlscarding of hip-spica cast. 6. There were no complication such as nonunion or delayed union in the cases with cast-brace.

For the study on the effect of retinoic acid on the formation of palatal rugae and the cleft palate, retinoic acid was administered orally 150mg/kg of body weight by gastric tube at GD 10.5 to Sprague-Dawley rats. The pregnant rats were sacrificed on GD 17.5 under ether anesthesia, and laparatomized. After removal of uterus, the number of pregnant sacs and fetuses were counted. The fetuses weighed, the MEE (medial edge epithelium) thickness measured and the mitotic figures counted after routine processing and H·E stain. All the palates were photographed, and the number of rugae & the rugal pattern analysed. TEM photographs of MEE cells were observed after routine processing. The results were as follows ; 1. Rat fetus body weight after retinoic acid treatment increased significantly compared with the control group. 2. Mitotic figures in the retinoic acid treated group increased significantly compared with control group. 3. In the retinoic acid treated group, 79.3% of fetuses had cleft palates. Among fetuses with cleft palates, complete cleft palates were 10.6%, incomplete cleft palate 89.4%. Incomplete clefts were of two types ; median type (cleft palate at the intermolar region) and soft palate type (cleft posterior to the 8th rugae). Median type was 64.6% and the soft palate type 35.4%. 4. 2.3% of the fetuses had the numerical anomaly of the palatal rugae in the control group, but that of retinoic acid treated group 87.7%. 5. 17.4% of palatal rugae of the control group was disrupted, but 100% of the retinoic acid treated group disrupted. 6. Rugal papillae were observed in the 15.1% of fetuses of the control group and 63.1% of fetuses of the retinoic acid treated group. 7. Longitudinal rugae were observed in 19% of fetuses of the retinoic acid treated group, but not in the control group. 8. In TEM photographs, cytoplasmic processes, intercellular space, and desmosomes decreased. Swelling of mitochondria & ER were also found in the retinoic acid treated groups. According to the above results, it appears that there is close relationship between palatal rugae and cleft palates, and that excess retinoic acid induces disruption of pattern and numerical variations of rat fetus palate rugae. Also retinoic acid has an inhibitory effect on the proliferation of medial edge epithelial cells of palatal shelves. The cleft palates may be induced by the above mentioned retinoic acid effects. But, the exact mechanisms of retinoic acid on cleft palate formation is not thoroughly known and should be further studied.

Kasabach-Merritt syndrome is the association of thrombocytopenia, disorder of coagulation, spontaneous bleeding and enlargement of a hemangima or extensive hemangiomatosis, which can be often life threatening. We experienced a three years-old girl with suddenly enlarging hemangioma of right cheek, complicated by severe thrombocytopenia, consumptive coagulopathy and hemorrhagic cystitis. Generalized petechia and ecchymosis were noted on the overlying skin of hemangioma, trunk and extremities. But the study of MRI and angiography, hypevascular was located within the right masseter muscle extending to temporalis muscle and anterior to parotid gland. So selective embolization with PVA (polyvinyl alcohol) was performed through the distal branch of internal maxillary artery and facial artery. She was medicated with oral corticosterioid for 3 weeks. After embolizationn, blood flow to hemangioma and facial swelling were markedly decreased. Patient was followed up for 7 years and she showed normal contour of face and no bleeding diathesis.

The hindfoot in the human body is known to play an important function for weight bearng, shock absorption and locomotion. The defect of hindfoot presents serious problems of the leg length discrepancy and weight bearing. Therefore, it is essential to reconstruct the defect of hindfoot. Up to date, many surgical modalities from a skin graft to the innervated osteocutaneous flap have been developed, but a completely satisfactory method of reconstruction has not been found. The ideal reconstructive method should provide sufficient padding tissue and sensibility. In the Department of Orthopaedic Surgery, capital Armed Forces General Hospital, two cases of hindfoot defect due to explosion were reconstructed by the midplantar fasciocutaneous flap with free iliac bone graft. The results of our procedure were very acceptable one year after the operations.

The ankle is a complex structure supporting the entire musculoskeletal system during standing and walking. The injuries to the ankle joint result in a severe functional disturbance because of complex anatomical characteristics around the ankle joint. 284 patients of the ankle fracture that were treated in orthopedic Dept. Capital Armed Forced General Hospital from march 1985. to march 1988. were analized in clinical and radiological aspects. The following results were obtained: 1. The main cause of the injuries was falling from a height and the other were sports injury and slipping down in order. 2. The most common type by Lauge-Hansen classification was supination-external rotation type(122 case, 42.9%). 3. 211 case(74.3%) were treated with open reduction and internal fixation, and 73 case(25.7%) were treated with closed reduction. Poor outcome seemed closely related to the severity of the injury and degree of fracture displacement. 4. Accurate reduction and rigid internal fixation of the lateral malleolus with shortening was important factor. 5. Classification of Lauge-Hansen was useful in the diagnosis and treatment of the ankle fractures.

OBJECTIVE: This study was aimed to investigate of newborn babies sex ratio in Seoul Seong Ae hospital and review of future problem. METHODS: We reviewed retrospectively the 21,332 cases of deliveries in women visiting at Seoul Seong Ae hospital from Jannuary 1994 to December 2003 (10 year's period). We investigated 1st baby and 2nd baby sex ratio and in case of 3rd baby, subdividing then into tree groups (first and second are female, first and second are male, first and second are male and female). We arranged the data at the base of childbirth registers and patients' obligation records. RESULTS: The results were as follows, 1. The total sex ratio in last 10 years was 111.2:100 (male:female). 2. 1st baby sex ratio was 109.2:100. 3. 2nd baby sex ratio was 110.6:100. 4. 3rd baby sex ratio was 133:100. CONCLUSION: These findings suggest that unbalance of sex ratio in 3rd baby is extremely serious trend in this country and is expected a tremendous social problems in early 21th century.

PURPOSE: The most important step for patients who come to the emergency department with ureter stones is acute pain management. There have been insufficient studies on what factors affect acute pain management for ureteral colic the most. In this study, patients with ureteral colic were divided into two groups: one group, in which the pain was first managed with an analgesic, and another group with unmanaged pain, to find factors that most affect additive analgesics administration for ureter stones. METHODS: There were 121 patients, eventually confirmed for the presence of ureter stones through a computed tomography CT scan, included in this study. When ureter stones were suspected after the initial patient evaluation, initial pain was assessed through numerical rating scale (NRS) and the first analgesic was administered once. Pain was reassessed through NRS after 30 minutes. At that time, if the pain was managed, the patient was assigned to Group 1. If the pain persisted, another analgesic was administered for the second and third time, and the patient was assigned to Group 2. Finally, ureter stones were identified through CT scan. RESULTS: There were 58 patients (47.9%) in Group 1 and 63 patients (52.1%) in Group 2. There were no statistically significant differences in average age, serum creatinine, size of ureter stone, and severity of hematuria between the two groups. The differences in NRS measured initially and after 30 minutes were statistically significant (7.6+/-1.4 vs. 8.6+/-1.2, p<0.001; 1.4+/-1.3 vs. 6.6+/-1.9, p<0.001, respectively). The presence of hydronephrosis and perirenal edema were also statistically significant (p<0.001, p=0.007). The affecting factor for the administration of additive analgesics was hydronephrosis (odds ratio 7.213, p<0.001). CONCLUSION: Hydronephrosis is an important factor in the treatment of patients with additive analgesics. It can also be used as a predictive index to assess the severity of pain in patients with ureter stones.
