Objective: Depending on the direction and degree of the septal deviation, the patient with malalignment-type VSD present with a variety of clinical syndrome. It is the purpose of this study to examine clinical characteristics of malalignment-type VSD, and to emphasize the clinical significance of septal malalignment in VSD and thus to increase the awareness for it. Methods: We analyzed echocardiographic or cardic catheterization and angiographic findings of 85 patients who were diagnosed as malalignment-type VSD at the department of pediatrics, Chonnam University Hospital between July 1990 and September 1992 Results: 1) Among 85 patients with malalignment-type VSD, there were 52 Cases (61. 2%) of Fallot-type VSD. 14 cases (16.5%) of Eisenmenger-type VSD, 19 cases (22.3%) of coarctation-type VSD. 2) All the 85 cases with malalignment-type VSD had the infundibular defects, and perimembranous infundibular VSD was most frequently associated with septal malalignment. 3) There was no prolapsing valve in all the cases with malalignment-type VSD. 4) Pulmonary hypertension was observed in all the cases with Eisenmenger-type and coarctation-type VSD. 5) Among the 19 cases with coarctation-type VSD, 8 cses (42.1%) were associated with coarctation of the aorth, and 3 cases (15.8%) with interrupted aortic arch. Conclusion: We conclude that septal malalignment in VSD has considerable clinical significance. Therefore, the authors believe that we should always consider the presence or absence of septal malalignment, in addition to the size and location of defect at the time of diagnostic evaluation of VSD, especially in the Koreans showing high incidence of infundibular VSD.

Together with review of literatures, authors reported a case of fatigue fracture of right 3rd metatarsal bone in an A-K amputee of lefe side, and added an amputation of contralateral lower extremity as a predisposing factor of fatigue fracture of metatarsal bone.

It has been known that osseous stability of the hip is dependent upon the inclination, anteversion and depth of acetabulum and also upon neck-shaft angle and anteversion of femur. Acetabulum enlarges from two different growth centers; one from the concave articular surface cartilage and the other from the triradiate cartilage. The former contributes primarily to the thickness of acetabular wall, where as, the latter to the central enlargement of the acetabular socket. Additionally the shape of acetabulum can be changed by deformity of the femoral head and neck, which can be explained by Wolff's and Hueter-Volkmann's laws. Yet there are still many factors to be clarified by clinical researchers in the future Authors in this experiment tried to clarify the role of triradiate cartilage and greater trochanteric growth plate upon the development of acetabulum. The material used for this study consiated of 30 rabbits of both sexes, aged 8 weeks. Animals were divided into 3 groups, and each group consisted of 10 rabbits In group I. hip was not injured and used as a Control: in group II, right greater trochanter with its growth plate was destructed completely; in group III, triradiate cartilage of right side was destructed. Subsequent to injury of Y cartilage ot greater trochanter with its growth plate, radiographs of the pelvis including hips were obtained weekly on each rabbit over 6 weeks period. and to evaluate the effect of injury upon the hip development acetatular angle, C-E angle, and acetabular depth and width were measured. The following results were obtained; 1. The shape of acetabulum of rabbits have showe remarable developmental changes until the 10 weeks of age after birth, but the changes became less remarkable by age of the 14 weeks. Thereafter it remained unchanged. 2. In group II, at the age of 14 weeks, compared with the values of the normal hip, the acetabular angle showed an increase of 1.9 degrees, and the center dege angle and acetabular depth showed a decrease of 3.21 degrees and 0.43mm respectirely. 3. In group III, at the age of 14 weeks, compared with the values of the normal hip, the acetabular angle increased by 18.9 degress while the center-edge angle decreased by 22.8 degrees. The acetabular depth showed a decrease of 1.81mm and the acetabular width showed an increase of 0.73mm. These observations suggest that the development of acetabulum depends largely upon the growth of triradiate cartilage, and also is affected secondarily by valgalization of femoral neck which is resulted by destruction of greater trochanteric growth cartilage.

The management of supracondylar fractures of the femur remains controversial. Most studies over the past twenty years have attempted to compare the results of non-surgical with those of surgical methods. Until a few years ago, conservative treatment was considered superior to internal fixation of supracondylar fractures of the femur. However, the development of new fixation devices and techniques have, according to several investigations, improved the results of the treatment of these fractures. The following clinical results were shown by analysis of 96 cases of supracondylar fractures of the femur treated in the Department of Orthopedic Surgery, Yonsei University, College of Medicine during the past 10 years from Jan. 1971 to Dec. 1980. 1. The prevalent age distribution was between 21 and 50 years of age (79.1%), and the ratio between males and females was 3.4:1. The most common cause of injury was car accidents (51.0%). 2. A classification of supracondylar fractures was unicondylar, simple supracondylar and intercondylar. Intercondylar which was subdivided into Type I, II-A, II-B, III according to Neer's classification. 3. Fifty nine patients (61.4%) were associated with injuries of other parts and the most frequent associated fracture was tibial fracture and the most common associated soft tissue injury was cerebral concussion or contusion. 4. The methods of treatment: conservative management by using skeletal traction for 34 cases, surgical treatment by open reduction and internal fixation for 58 cases and A-K amputation for 4 cases due to populiteral artery injury. 5. Fifty nine cases were suitable for result analysis. The satisfactory result of surgical treatment was 63.4% and conservative treatment was 50.0% respectively. The factors affecting the final results were Type of fracture, severity of injury, and rigid internal fixation. 6. The main complications of the supracondylar fractures of the femur were delayed union (10.2%), infection (10.2%), and traumatic arthritis (13.3%). 7. Finally, the results of treatment depend largely on anatomical reduction, rigid fixation, early joint motion.
