PURPOSE: Evaluation of clinical and radiologic results of THR using HA-coated femoral stem. MATERIALS AND METHODS: From Jan. 1991 to Dec. 1992, we carried out 177 cases of Total Hip Arthroplasty using hydroxyapatite-coated implants of 167 patients, and among thses, 153 cases in 144 patients were followed up more than 24 months. The implants used were 74 cases of Mallory-Head Hip system, 41 cases of Omnifit system and 38 cases of Profile system. RESULTS: The average Harris Hip Score was 48.3 points preoperatively, 94.7 points at POD 1 year and 95.7 at POD 2 years. Seven patients(5.2%) complained thigh pain at POD 2 years. On the radiologic findings, cancellous condensation was noted around the hydroxyapatite coating region of femoral stem in 84 cases(54.2%), and radiolucent lines were noted at the non-coating region of distal stem in 102 cases(67.7%), but were less than 2mm and not progressive. There was no statistically significant differences among the groups of these three implants(P < 0.05). Comments : This early result of femoral stems with hydroxyapatite-coating was quite satisfactory, however, long-term follow-up studies will be necessary.

In clinical microsurgery, limitation of space often prohibits rotation of a double clamp in an end-to-end anastomosis, or shortage of length of the secondary vessel in an end-to-side anastomosis does not allow visualization of the back wall. In these situation, back wall repair is extremely difficult. To overcome this problem, we use continuous suture technique without rotation of double clamp for end-to-end and end-to-side anastomosis of the 40 rat femoral arteries. After continuous sutures for micro-arterial anastomosis, the following results were obtained: Continuous sutures are useful in anastomosis where there is unavoidable limited access to the posterior wall and for some of the larger vessels now being anastomosed in free flap and other reconstructive surgery.

Keloids are abnormally healed skin wounds that develop in the subpapillary layer of the dermis. They are a lesion with wide, raised and deep scars. They exceed the original dimensions of the wound and grow mounds upon mounds of collagen in a pseudotumor fashion. Their treatment may take several forms such as surgery, intralesional injection of steroid, compression, superficial irradiation, and combination therapy. However, absolute method is nothing until now. Recently, the cryosurgery shows relatively good effect in treatment, so we tried the clinical experience with cryosurgery in the treatment of keloids. Material and methods: During the past 2 years, we treated 20 individuals of the keloids with severe itching and pain. The age ranged from 5 to 45 years old. Only 6 cases were biopsied before and after cryotherapy. The cryosurgery set we used was Toitu model CR 201 N₂O gas (tip temperature in ­80℃) and was applied directly on the lesion about 4 to 5 minutes with slight compression. After cryosurgery in keloids, the following results were obtained: 1. It is both quick and easy method. 2. It is causes little or no pain and no loss of blood. 3. Integumentary normalization is rapid. The new scar tissue is smaller, and more elastic and soft. 4. The pain, itching and paresthesia commonly associated with keloid is usually disappeared. 5. Other treatment can be used after cryosurgery. 6. Histologic picture after cryosurgery is similar with the result of steroid injection. 7. The mechanism of the cryosurgery in keloids is the result of the direct tissue destroying action and cryoimmunologic reaction.

Menetrier's disease is a rare, characterized by the presence of large rugal folds involving part or all of the stomach. Patients with hypertrophic gastropathy often have distressing abdominal symptoms, weight loss, and edema due to gastric protem loss. A 64 year old male patient was admitted with the chief complaint of epigastric discomfort. Endoscopic, radiologic and histologic examination, revealed characteristic findings of Menetrier's disease. A case of Menetrier's disease is reported with a brief review of literature.

Mitral valvular orifice area is important for the evaluation of prognosis and treatment of patients with mitral valvular stenosis. Until recently, Gorlin's formula using cardiac catheterization has been utilized in the measurement of mitral valve area, but it is invasive and impractical to examine repeatedly. Recently 2-Dimensional echocardiography appeared to be a practical and useful substitute in measurement of valve area and also it is economical and has no risk to patients. In 31 patients with mitral valvular stenosis examined at the echocardiography room of Busan national University Hospital from March 1982 to March 1983, we measured the mitral valve area with 2-Dimensional echocardiography and evaluated its relationship with the left ventricular functions measured on M-mode echocardiogram. Among many parameters on M-mode measurements EF slope, excursion amplitude and the ratio of left atrial dimension to aortic root dimension were rather helpful for the assessment of severity of mitral valvular stenosis than other parameters. And each relationship with the valve area showed correlation coefficient of 0.60, 0.05 and -0.58, respectively.

Horizontal Mattress Suture Technique on Microvascular Anastomosis of rat (body weight: 200-250 gm) femoral artery was evaluated. The present study was conducted to compare the horizontal mattress suture with simple interrupted suture on the suture time, patency rate of the sutured vessels, and the histological changes of surgical site of the vessel wall during wound healing period. The mean suture time of the vessel wall with horizontal mattress suture technique was 15 min 49 sec ± 2.14, which is significantly shorter than that of simple interrupted suture technique. The patency rate of the sutured vessel in both groups was statistically not different each other till post-operative 3rd day but patency rate of horizontal mattress suture was higher than that of simple interrupted suture at post-operative 3rd week. The histological findings such as intimal noss, medial degeneration and intimal regeneration were similar in both groups.

A typical synovial osteochondromstosis within the both knee joints occured in a 29-year-old man. The patient complained of palpable masses in the both knee joints showed multiple round, oval, amorphous calcified loose bodies. Arthrotomy of the left knee joint, removal of loose bodies and total synovectomy were performed. The microscopic findings of loose body revesled a degenerated cartilage cap and showed ares of cacification, ossification and fibroadipose tissue in the central part of the body. The mocroscopic findings of synovium revesled a cartilagenous metaplasis of the fibro vascular tassue and showed no evidence of calcification or ossification. The cartilagenous tissue was relatively matured form.

From March 1985 to Sep.1985, Transcatheter hepatic arterial embolization was perfromed in 17 primary heptomaand 8 metstasis of liver in Department of Radiology, Yonsei University College of Medicine. Metastatic cancers ofliver were one nasopharyngeal cancer, one small bowel leiomyosarcoma, one gall bladder cancer and 5 colon cancers.The used embolization materials were the followings: Gelfoam particles for one primary hepatoma, 95% absoluteethanol for 4 patients, Ivalon(250-590micro m) for 19 patients and autologous blood clots for one metastasis, Theresults were summarized as the follows: 1. The devascularization of tumor vessels in post-emblization hepaticangiogram was complete in 6 primary hepatom and one metastasis and partial in 11 primary hepatoma and 7metastasis. 2. In the follow-up CT evaluation 3 to 4 weeks after embolization, well necrotic density was revealedin 8 primary hepatoma and one metastasis. 3. The complications were fever with higher than 38 degrees C(92%),abdominal pain (72%) and nausia or vomiting(40%). They were subsided wtihin one to 7 days after embolization. 4.In liver function study, sGOT and sGPT were elevated in 80% of total cases and returned to normal within 15 to 30days. LDH was variable. In 4 cases of absolute ethanol infusion, above liver enzymes were markedly elvated as 10times or more as normal range.
