The soleal line in 115 (left; 61, right; 54) cases of tibiae was studied morphometrically by the method of Mysorekar and Nandedkar. 1. The soleal line showed a uniform character throughout in 26 cases and a mixed characters in 89 cases. The bones showing uniform character were seen generally as a lineal line or wide line. 2. The soleal line having mixed characters divided into three parts. In the upper and middle thirds, the major type of line was wide line. In the lower third, the line was commonly seen as a lineal line. In about 12% of the bones examined the line was seen as a groove, particularly in the middle and lower thirds. 3. The soleal line commenced 1-2cm below the fibular facet In about 61% of cases. 4. The length of the soleal line was 10.5cm, and the ratio to that of the tibia was about 30%. The results of this study provide the characters of the soleal tne of the tibia in Korean. The soleal line, unlike the textbook description, generally shows mixed characters of a line.

There has been no adequate diagnostic method for the diagnosis of intrascrotal lesions until recent days. Butafter the development of radionuclide testicular scan, early and relatively accurate diagnosis of the testicularlesions are possible. So the authors analyzed the 32 cases of patients who were examined by testicular scan andconfirmed by follow up study or operation, and the results are as follows; 1. These 32 cases consists of 13 casesod epididymitis, 7 cases of testicular torsion, 4 of cryptorchism, 2 of testicular tumor and etc. The over alldiagnostic accuracy is about 69%. 2. In epididymitis, the diagnostic accuracy is 85%(11/13) and the findings ofscan are increased perfusion in radionuclide angiogram and hot activity noted mainly in peripheral portion of thetesticle in static image. 3. In cases o testicular torsion, diagnostic accuracy is 86%(6/7). Acute torsion showsnormal perfusion in angiogram and round cold area instatic image. But in missed torsion, perfusion is increasedand round cold area wit surrounding hyperemia is noted in static image. Radionuclide testicular scan seems to benoninvasive, inexpensive, easily available and simple to perform with low gonadal radiation dose. So it can bevery useful as the first study in patients with acute testicular symptoms.

The etiologic factors causing low back pain are numerous and variable. Orthopaedic sugreons tend to focus attention to any defects of structural and functional origins such as pine, discs and facet joints. Clinically, however, the fact remains that not all abnormal findings produce back pain and vice vera. Among the many modalities of investigation to determine the etiology of back pain, plain X-ray of the lumbosacral spine is the single most important acreening method. In addition to antero-posterior, lateral and oblique views, stress view of the spine gives certain clue to predict the disc degeneration. The X-ray findings of a total of 503 patients with low back pain (the study group). admitted during the year of 1977 to the Department of Orthopaedic Surgery, National Medical Center, were reviewed and compared with the control group of 100 patients without relevance to back pain (the control group). Our intention was to explore the relationship between the abnormal findings of plain X-rays and occurence of back pain. and to further entrance the diagnostic value of the spine. The study group of 503 patients (86 cases of which were operated on) were diagnosed not only by routine plain X-rays but also by contrast myelography and tomography in addition to detailed physical examination. Following observations were made: 1. The sex was nearly equally distributed in the atudy group of 503 patients. The age ranged from the second to the eighth decade, dominant group being the third to fifth decades. 2. The causes of the low back pain were herniated disc, spondylosis, spondylolysis, and infection, in that order. 119 patients (23.7%) out of the 503 showed no roentgenologicaI abnormal findings. 3. 384 cases out of the 503 revealed abnormal findings, mainly congenital or developmental and degenerative changes in that order. 4. In a comparative study with the control group, congenital or developmental anomalies and degenerative changes were not related to low back pain. Disc. space narrowing, supposed to be valuable in establishing the diagnosis of low back pain was present in 26% of the cases in study group and in 11% in the control group. 5. The age incidence of the low back pain with congenital or developmental anomalies was mainly in th second and third decades, while that of disc space narrowing was in the third to fifth decade. The degenerative changes of the spine appeared after the fourth decade. 6. Transitional vertebra and tropism are supposed to plsy a role on the degenerative change of the spine. 7. The stress study of the spine had some benifit it the diagnosis of disc degeneration. The mobility of the L4-5 lesion with low back pain was increased to mean 15.1 and standard deviation 3.7, in comparison to the mean 12.3 and standard deviation 3.7 in the control group.

Femoral head and neck fractures during the course of avascular necrosis are rare with only few reports in the English literature. Moreover, there are very few reports on an analysis of the patterns of these fractures. Four cases of femoral head fracture caused by minor trauma, which were quite different from the crescent fractures during the course of avascular necrosis were analyzed in regard to the underlying disease, causes, sites, types, directions, pattern of fractures and the injury mechanism of the fractures. The results are reported with special regard to the pattern of the stress fracture of the femoral head and neck during the course of avascular necrosis.

Hyperextension injury in the thoracic spine is uncommon with only a few cases documented in the literature. The mechanism of these injuries is hyperextension combined with axial or shearing force. These types of injuries are associated with a high risk of dural tears and paraplegia. A 91-year-old female presented with acute back pain from a hyperextension injury in thoracic spine with no neurological deficit. Lumbar magnetic resonance imaging showed a intervertebral disc rupture. On day 20 of hospitalization, the herniated intervertebral disc compressed the spinal cord with incomplete paraplegia. Hyperextension injuries involving the three columns are very unstable and we recommend surgical treatment as soon as possible, not only because of the initial trauma, but a ruptured disc herniation can damage the spinal cord.

OBJECTIVE: To analyze the efficacy of intracytoplasmic sperm injection (ICSI) for totally unfertilized oocytes by the conventional insemination during in vitro fertilization and embryo transfer (IVF-ET) METHODS: From March 1996 to April 1998, 15 couples who experienced total fertilization failure after conventional IVF without severe male factor infertility in semen analysis were evaluated. Fertilization were assessed by the presence of 2 pronucleus (PN) after 14-16 hours of conventional insemination. All unfertilized oocytes were reinseminated by ICSI and checked for signs of fertilization between 6-10 hours after ICSI. The embryos with fertilization and development were transferred to the uterine cavity and the outcome was analyzed. RESULTS: Total numbers of unfertilized oocytes were 120, and total numbers of oocytes injected on day 1 using ICSI were 102. Total numbers of oocytes with normal fertilization after ICSI were 74 and mean fertilization rate of 71.1 +/- 24.0% was obtained. The numbers of embryos transferred was 3.6 +/- 1.7. The biochemical pregnancy rate was 13.3% (2/15) and the clinical pregnancy rate was 6.7% (1/15) per cycle. CONCLUSION: ICSI to totally unfertilized oocytes by conventional insemination technique during IVF-ET on the next day of oocyte retrieval seems to be a relatively successful mean and afford a chance of pregnancy to the infertile couples whom the ET could not perfomed to because of total fertilization failure."

The purpose of this study was to investigate the effects of ICB(Irradiated frozen allogenic bone, Rocky Mountain Tissue Bank, USA) and MTF(Decalcified freeze-dried bone allograft, Musculoskeletal Transplant Foundation, USA) on the cell proliferation and differentiation of human fetal osteoblasts. Human fetal osteoblasts (hFOB1) were cultured with 10 ng/ml of ICB and MTF. The negatvie control group was cultured with DMSO and positive control group was cultured with BMP (2 ng/ml). MTT was performed to examine the viability of the cell, and alkaline phosphatase activity was analyzed to examine the mineralization. Calcium accumulation was also evaluated. ICB and MTF did not increase the rate of the cellular proliferation of hFOB1s while they enhanced ALP and calcium accumulation. The expression of osteocalcin (OC) and bone silaloprotein (BSP) increased in hFOB1 treated with ICB and MTF (10 ng/ml). These results suggest that ICB and MTF stimulate osteoblastic activity of the hFOB1.
