A fracture of the femoral neck in a young adult differs from the same fracture in an older patient in the following respects; 1. A relatively uncommon injury. 2. A significant difference in the severity of trauma. 3. A less satisfactory result. At the point of view, we studied the femoral neck fcartures in 15, 20- to 50-year-old patients. The aims were to analyze why these fractures occur in young adults, and what results can be expected after internal fixation. The results were as follows; 1. Common in men (3:1). 2. 80% (12/15 cases) of the fractures were caused by severe trauma. 3. The 3 cases (20%) were associated with the other fractures. 4. The factors infuencing the clinical results and complications in our study; a. Severity of trauma. b. Degree of displacement. c. Existence of posterior comminution. d. Time interval between accident and operation. 5. The multiple pinning got the more rigid fixation and diminished the rate of fixation failure. 6. All cases were achieved good to acceptable reduction. 7. Satisfactory functional results were achieved in 93.3%. 8. The rate of avascular necrosis was 15.4% (2/13 cases). It is concluded that the most of femoral neck fractures in younger patients occur because of the significant trauma. In our study, the incidence of avascular necrosis was not greater than in order patients. Therefore, to get as good a result as possible it seems important to perform the anatomical tion and rigid internal fixation with or without bone graft.

Spinal stenosis is defined as any type of narrowing of the main spinal canal, nerve canal or foramina caused by bony or sourrounding soft tissues. Its pressure symptoms are characterized by ill localized back pain, and usually bilateral chronic sciatica. During the past 80 years, the knowledge subjected to the spinal stenosis has been inproved but still many problems are remaining to be solved. Recently, the diagnosis and treatment of spinal stenosis have been facilitated due to introduction of computerized tomographic scanning apparatus. During the period of 3 years, from May 1979 to March 1982, we experienced 40 cases of spinal stenosis at Han Gang Sacred Heart Hospital and Gang Nam Sacred Heart Hospital. In study of this 40 cases clinical and radiological evaluation were made and obtained following result (25 cases of which were operated on). 1. The most common type was degenerative one (50%) 2. There were 16 males and 24 females (4:5) 3. The age distribution showed a peak incidence is the third decade (25%) 4. The most common chief complaint on admission was ill localized chronic sciatica (50%) 5. Decompressive surgery was carried on 25 cases such as; Laminectomy only (8%), Posterolateral fusion (20%), Both Laniinectomy and posterolateral fusion (72%) 6. The longest follow-up was 3 years and the shortest one was 4 months and the average was one year and four months. The outcome of follow-up were; excellent (52%), good (40%), fair (8%), poor (0%).

Deep vein thrombosis is a frequently lethal complication following musculoskeletal surgery and skeletal trauma. For this study on incidence of deep vein thrombosis, we examined the data on 40 patients with contrast venography. Thrombosis limited to the veins in the calf of the leg was shown in 10 patients by venography. None of these patients had clinical symptoms of deep vein thrombosis or indicating embolism. We therefore concluded that the incidence of deep vein thrombosis of the lower extremity after injury or operation in Korea is not so rare as was considered before.

10.Correlation between Chromosome Abnormalities and Genomic Imprinting in Developing Human 2) Independent Expression of Imprinted Genes, H19 and Insulin-like growth factor II (IGF2), in Androgenetic Hydatidiform Moles.

Human uniparental gestations such as androgenetic hydatidiform moles provide a model to evaluate the integrity of parent-specific gene expression,-i.e, genomic imprinting,- in the absence of a complementary parental genetic contribution. Several imprinted genes are characterized so far including the insulin-like growth factor-2 gene (IGF2) coding for a fetal growth factor and the Hl9 gene whose normal function is unknown but which is likely to act as an untranslated mRNA for its tumor-suppressing function. IGF2 is expressed exclusively from the paternal allele while Hl9 from the maternal allele. Such an alternate expression is quite interesting because both Hl9 and IGF2 genes are located close to each other on chromosome 11p15.5. An in situ hybridization analysis has shown strong expression of Hl9 and IGF2 alleles in nine hydatidiform moles. Especially, a prominent expression of Hl9 and IGF2 was detected in cytotrophoblast and the cellular localization was almost paralleled in Hl9 and IGF2 transcripts . Hl9 and IGF2 genes could be expressed either biallelically or monoallelically in the moles. However, IGF2 biallelic expression did not affect allele-specificity of Hl9 expression.. These results suggest that both H19 and IGF2 transcripts are expressed in the same cells and that the functional imprinting of H19 and IGF2 genes in hydatidiform moles can be controlled individually and independently of each other.
