The concept of surface replacement arthroplasty of the hip is to replace the diseased joint surface with artificial plastic and metal cup in the acetabular and femoral head respectively, and to restore the normal anatomy and gain biomechanical function. Ten cases of Wagner type's surface replacement arthroplasty performed in Department of Orthopedic Surgery, Seoul National University Hospital since July 1979 are reviewed, and their minimum follow up is two months. In terms of the Pain control and improvement of range of motion in the hip, surface replacement arthroplasty showed about the same result compared with conventional total hip. In our cases there was no one complicatian, even though it is too short to evaluate the result of this operation. Wagner recommends surface replacement arthroplasty to perform through anterior approach, but 2 cases of our ten patients that have relatively good range of motion of the hip could be operated on this surgery by anterolateral approach (oblique skin incision) without trochanteric osteotomy, because of high incedence of myositis ossification with anterior approach. It is our conclusion that surface replacement arthroplasty of the hip may be used as an interim procedure to gain time in young patient who needs conventional total hip replacement which reveals increasing complication with the lapse of time.

Twelve neglected congenital dislocations of the hip in ten patients over the age of eight years were treated by open reduction and chiari osteotomy. Reduction was aided by preoperative traction only in two hips, by femoral shortening with preoperative traction in three and by femoral shortening only in seven. The average follow up period in our series is 3 years, ranging from 1 year and 2 moths to 4 years and 5 months. The overall results were good but one case of avascular necrcsis and one case of redislocation were seen. By our experience it is thought that all old and congenitally dislocated hip in the growing age can be reduced by femoral shortening with soft tissue release, and preoperative traction for its reduction is not undispensable. The most problem in the treatment of the old congenital dislocation of the hip is the postoperative partial ankylosis in the affected hip and this problem would be overcome by delicate operative technique and meticulous hemostasis.

OBJECTIVE: The purpose of this study was to evaluate the effect of polycystic ovarian follicular fluid on sperm motility in human in vitro fertilization (IVF). METHODS: From May, 1998 to July, 1999, 55 patients who complained of infertility were involved in this study. We obtained ovarian follicular fluids form the patients by ultrasono-guided aspiration. Subjects were divided into two groups. 20 patients who had polycystic ovarian disease were belong to study group, and 25 patients who had normal ovarian follicular fluid were belong to control group. The follicular fluid dilution was done with Ham's fluid as 10%, 20%, 50%, 100%. The sperm motility was analyzed by CASA at 6hr and 12hr after incubation in follicular fluids. RESULTS: The levels of average path velocity (VAP) in all concentration fluid didn't show significant difference between study and control group. The other parameters including curvilinear velocity (VCL), amplitude of lateral head displacement (ALH), and linerity (LIN) were didn't show any significant difference between both groups. CONCLUSION: PCOD fluid had seemed to have an adverse effect on the sperm biological function. But, this study showed that PCOD fluid had no different effect on sperm motility with normal follicular fluid.

The aim of present study was to determine the efficacy of immunotherapy with paternal lymphocytes for unexplained infertility. It has been apparent that reproductive success may be affected by the presence of abnormal autoantibodies. Unexplained infertility and repeated pregnancy wastage has been reported in the presence of abnormal autoantibodies. These data suffest that abnormal immune function may be an important pathologic entity contributing subfertility in patients with unexplained infertility. Therefore, immunotherapy may be a possible treatment modality for patients with unexplained infertility. Some investigators have reported that a proportion of infertile couples with repeatedly unsuccessful ET showed close histocompatibility similar to those of spontaneous recurrent abortion. Recently, it has been noted that immunotherapy with paternal lymphocytes achieves a high efficacy in preventing subsequent abortion in women with primary recurrent abortion of unknown cause, which was mediated by immune reaction including blocking antibody. To substantiate the hypothesis, we applied immunotherapy preceding Peritoneal Oocyte and Sperme transfer (POST) to 43 patients, 47 cycles of 82 patients, 89 cycles with at least three previous IUI failure from April, 1993 to February, 1995. There were no significant differences between treatment and control group in clinical response and hormonal response to controlled hyperstimulation. there was no significant difference between treatment and control group in pregnant rates per cycles (42.6% versus 28.6%), but a significantly lower abortion rate per pregnancy in treatment group, with 10.0% (2/20) compared with 50.03% (6/12) in control group. This study may suggest that immune therapy for patients with unexplained infertility with paternal lymphocytes might be beneficial.

Although the goal of fracture treatment is alive bony union with anatomical reduction, prosthetic replacement is indicated for some complicated femoral neck fracture. However it is not defined until now which one is selected between hemiarthroplasty and total hip replacement for the delayed or complicated femoral neck fracture. In order to get the criteria which one is better for this patient when indicated, we reviewed the result of 39 endoprosthetic and 16 total hip replacement patients at Seoul National University Hospital between June of 1975 to June of 1980. Both methods of endoprosthesis and total hip replacement showed satisfactory results of 72% and 90% respectively. Considering two points of the pain-relief and walking ability, total hip replacement is believed to be far better than endoprosthesis, especially for those patients who are over 50 years of age and have had more active living conditions before fracture.

The dynamic blood flow is regulated by the numerous complex mechanisms. Since blood flow varies directly with the radius of the vessel, blood flow is markedly affected by small changes in the caliber of the vessels. Using the hotoplethysmography, we assessed the relative changes of blood flow after topical application of the vasoactive drugs to the femoral arteries of the rabbits. It is the purpose of this study to evaluate the immediate and delayed effects of the vasoactive drugs such as epinephrine, methylergonovine, chymopapain, and lidocaine in course of time when the drugs applied topically to the vessel. 60 rabbits were divided into 6 experimental groups. In group I, the femoral artery was surgically exposed only. In Group g-A, epinephrine was applied to the femoral artery after surgical exposure. In Group Il-B, after spplication of epinephrine, the effect of epiniphrine was reversed with lidocaine. Another drugs were applied as follows methylergonovine in Group Hl-A, methylergonovine and lidocaine in Group Ill-B as in group Il-B, Chymopapain in Group lV. The relstive changes of blood flow were measured by the photoplethymograph for 3 weeks. The results are as follows ; 1. The amplitude of the photoplethysmographic wave decreased immediately after the topical application of epinephrine, methylergonovine and chymopapain. Such an effect could be observed until the 3rd week after the topical application of the drugs, 2. The delayed dffect of reducing the amplitude could be seen during the 1st week in the epinephrine and methylergonovine treated groups. However, it was seen after 1st week in the chymopapain treated group. 3. The delayed effect of epinephrine and methylergonovine could be reversed with lidocaine. 4. It seems that lidocaine can be used clinically to preyent the delayed effect of epinephrine and methylergonovine.
