Seventy consecutive ipsilateral fracture of the femur and tibia in sixty-eight patients from December 1974 through December 1984 treated at Severance Hospital were analysed in clinical and radiological aspect. 1. Fifty-nine patients were male and nine patients were female. The male patients were more injured in the ratio of 6: 1. The avarage age was 34. 2. The main cause of injuries were traffic accidents; 59 patients. (86.8%). 3. The majority of the fractures were shaft fracture; for example, femur shaft 57% and tibia shaft 47%, The open fracture of the tibia was 34% and the femur was 17%. 4. There were 24 cases of concomitant fracture and dislocation of other sites. A fat embolism was disgnosed in 4% of the patients. Four patients had died one month after sustaining injuries. 5. Over-all, a good or excellent functional result was achieved in 76% of the patients treated with internal fixation of both fracture, 65% of the patients with intexnal fixation for the femur fracture only and 35% of the patients managed conservatively.

In general, the three major oral functions of edentulous patients-mastication, phonation, esthetics-can be rehabilitated by the complete dentures, and both the resin based complete denture and the metal based complete denture are commonly used by many clinicians today. For the sake of many advantages such as the excellent thermal conductivity, low volumetric change, high strength, low risk of fracture and the better patient's adaptation, the metal based complete dentures are indicated to the several cases. But, there are common failures of these type of dentures mainly by the fracture or the debonding between the resin structures and the metal frameworks which is caused by the discrepancies by the discrepancies of the flexural strength and the coefficient of thermal expansion. This is aggravated by the water contamination of the interface when exposed to the oral environment and results in the failure of complete denture treatment. So, the purpose of this study is to compare the bond strength and the fracture patterns of the gold alloy based and the Co-Cr alloy based complete dentures using the PMMA resins and the 4-META adhesive resins. The results of this study were as follows. 1. Both to th PMMA resin and the 4-META resin, the flexural bond strength of gold alloy is lower than that of Co-Cr alloy(p<0.05). 2. To the Co-Cr alloy, the bond strength of the 4-META resin is significantly higher tan that of PMMA resin(P<0.05). 3. The flexural strength of the group with the mechanical retention form is significantly higher than that of the group without retention form(P<0.05). 4. Comparing with the other groups, the fracture patterns of the group 3 are quite different from the group 1, 2, 5.

The Waltons method-a method of dynamic reconstruction of old ligament injuries of the knee and a combination procedure of O'Donoghue, Bosworth, and Slocum-was introduced with one case experience. This method seemed to be better than other reconstructive procedures, especially in the aspect of rotatory and valgus instability of the knee.

Separation of the symphysis pubis in association with delivery is very rare. The Korean orthopedic and obstetrical literature pertaining to this syndrome is absent. The physiological widening is small and asymptomatic, but a separation of more than one centimeter may occur and in usually symptomatic. A twenty-six-year-old woman of separation of symphysis pubis associated with delivery was treated successfully with the treatment of reduction and pelvic band, with absolute bed rest in the lateral decubitus position.

We performed 75 cases of daryocystorhinostomy from Jan. 1988 to Dec. 1990. A routine dacryocystography was performed prior to operation in all cases. A modified T oti's method was applied as a surgical technique "H" shaped incision was done. Both anterior and posterior flaps were sutured adequately and vaseline guaze was used as a plugging agent for 7 to 10 days Success was achieved in 72(96.0%) of 75 cases. The causes of 3-failures were organized granulation tissue and trauma.

PURPOSE: Since the introduction of short vein bypass (SVB), many have reported its feasibility when long vein bypass (LVB) cannot be performed due to limited vein conduit. However, the presence of inflow-vessel disease may affect graft patency and thus require endovascular treatment prior to surgery. Our study aims to analyze the results between SVB and LVB. MATERIALS AND METHODS: From 2009 to 2013, 27 bypass procedures were reviewed retrospectively. Outcomes such as patency rate, postoperative ankle brachial index (ABI) and limb salvage rate between SVB and LVB were compared. Wound healing time and primary patency rate were analyzed and the former was also analyzed according to the respective angiosome and revascularization type. RESULTS: There were 11 males and 16 females and the mean age was 66.6+/-12.3 years. Twenty four patients had TransAtlantic Inter-Society Consensus (TASC) D and 3 patients had TASC C lesions below knee. The 1-year cumulative patency rate between SVB and LVB were 63% and 66%, P=0.627. The limb salvage rate (100% vs. 73%; P=0.280) and postoperative ABI (0.592 vs. 0.508; P=0.620) were higher in the SVB group than in the LVB group, although the differences were not significant. There was no difference in wound healing time by angiosomal revascularization type. In situ vein graft showed higher patency rate than reversed greater saphenous vein (75% vs. 61%; P=0.00) CONCLUSION: The results of SVB were similar to those of LVB. SVB is feasible in the setting of limited conduit availability, in combination with endovascular treatment in the presence of proximal lesions.
