Triple arthrodesis was performed on 167 feet in 153 patients at the Department of Orthopaedic Surgery, Seoul National University Hospital, during the 19 years from July 1957 to March 1976. Review of statistics, technical problems, and complications has led to following conclusions. 1) Of the total of 167 feet, residual poliomyelitis was the most common etiology with 127 feet (76%). 2) The youngest age was 5 years and the oldest 54 years, the 12–17 year group with 84 feet occupying half of the cases. 3) 79 feet (46.7%) had equinovarus deformity and 27 feet had equinocavovarus. 13 feet had no deformities. 4) Hoke's lazy S incision was utilized in 110 feet and Olliers incision in 57 feet. Hokes technique was employed in 118 feet and Lambrinudi's technique or its modification in 44 feet, while in the 5 feet without deformity exeresis alone was performed. Steinmann pins were used in 121 feet for temporary internal fixation and staples were used in 39 feet. 7 feet had no internal fixation. The senior author (D.Y.L.) routinely employs Hoke's incision, Hoke triple arthrodesis and Steinmann pin fixation, while when there is no deformity simple exeresis may be performed. 5) In our opinion, Hoke triple arthrodesis can correct any deformity and is particularly suitable in severely deformed rigid feet, since excision and replacement of the head of the talus affords better exposure and mobilization as well as easier set-up of the foot. 6) Whenever necessary, triple arthrodesis was combined with tendo Achilles lengthening, percutaneous plantar fasciotomy, posterior capsulotomy, medial or posteromedial release, subtalar and midtarsal wedge osteotomy, tibiotalar arthrodesis, supramalleloar osteotomy, and transmetatarsal osteotomy, followed by cast wedging or tendon transfers if indicated. 7) There was no nonunion in our cases. Clinically significant skin necrosis and wound sloughing occurred in 8 feet, gross postoperative infection in 2 feet, secondary osteoarthritis of the ankle in 2 feet, significant residual equinus deformity in 8 fret(in seven tendo Achilles lengthening was not done and in the one with tendo Achilles lengthening the deformity had been extreme and rigid), residual varus deformity in 3 feet, and residual valgus in 1 foot. These major complications occurred mostly in older children and adults, in whom deformities were severe and rigid and extensive surgery was necessary in order to achieve adequate correction. In such feet, correction is extremely difficult and greater risks of a variety of complications demand meticulous attention to technical details and postoperative care.

Based on clinical, operative and pathological finding in twenty six cases of giant cell tumor, treated by curettage and bone graft in 14 and resection and bone graft in 5 buring 19 years, from 1958 to 1976, following results were obtained. Even in this study, according to others, giant cell tumors were mostly located around the knee in 16 cases. Following up results postoperatively, the overall recurrence rate of giant cell tumor was 38 percent. Especially in curettage and bone graft, it was recurred in 43 percent. Tumor located around the knee and vertebrae showed higher rate of recurrence than those in other sites. Four of the six patients who had an episode of recurrence recurred within the second years, and the other one in the third years after curettage and bone graft. All the two cases who had experienced a second recurrence were resulted in recurrence within second years after curettage and bone graft. Three of six patients treated by curettage and bone graft as secondary treatment had no recurrence.

PURPOSE: Because cryptorchid testes are known to undergo histopathologic changes affecting development, maturation, and tertility, early surgical correction is usually recommended. However there are differing opinions concerning whether retractile testes are affected by similar changes and also whether there is a need for surgical treatment. We aimed to assess the histopathologic changes in retractile testis by studying the changes in testes artificially placed back in the abdomen after they have descended to scrotum in experimental rat models. MATERIALS AND METHODS: Male Sprague-Dawley rats were divided into 3 groups; a control group(controls), prepubertal ascent group (P) in which testis were placed back intraabdominally by bilateral inguinal canal obstruction at 6 weeks, a neonatal group(N) in which intraabdminal testis was induced by bilateral inguinal canal obstruction at birth. The relative weight of the testis, morphology of the seminiferous tubules including Leydig cells, tubular degeneration phase(TDP), spermatogonia per tubules(S/T), and Sertoli cell index (SCI) of these three groups were analyzed and compared. RESULTS: The relative weight of testis was significantly decreased in the group of N(0.0016+/-0.001) and P(0.0015+/-0.0002) compared to controls(0.0037+/-0.0002) (p<0.05). The S/T value was also decreased in P(2.05+/-18.2) and N(73.2+/-32.4) when compared to controls (360.2+/-21.3). Similar changes were observed in SCI of both P(64.5+/-6.4) and N (91.2+/-14.2) when compared to controls (227.9+/-31.1). Only minority of N and P showed higher TDP values. However, although statistically insignificant, TDP was increased in both P and N when compared to controls. The Leydig cells in N and P showed cellular distortion and hypertrophy. CONCLUSIONS: This study demonstrate that prepubertal ascent, similar to that of innate cryptorchid testis, also can induce histopathologic changes such as changes in testicular seminiferous tubule, decrease in the S/T value and decrease in SCI value. Our findings supports that hypothesis that retractile testis may cause histological damage thus surgical correction may also be warranted similar to in case of genuine cryptorchism.

We report the implantation of a balloon-expandable intravascular stent at proximal left anterior decending artery in a patients suffered from Canakian functional class III angina for 8 years. The patient received 3 times percutaneous transluminal coronary angioplasty at proximal left anterior descending and circumflex artery without benefits. Repeated angiography revealed restenosis at proximal left anterior descending artery. Atherectomy was tried with transluminal extraction catheter(TEC) with luminal dissection and coronary bypass graft followed. occluded vein grafts were defined by follow-up angiography and chest pain recurred. No residual stenosis or thrombosis was documented in 24 hour follow-up angiography and the patient was discharged without symptom at 10 days after stenting.

Regular hemodialysis has been established as a way of treatment for end stage renal failure. In adults, hemodialysis 5 hours each time, three times weekly with one square meter hemodialyzer is now widely accepted as a standard, and there are many reports on long term follow up studies. Quite a large difference are present, however, in our community mainly originated from patient's poor compliance in frequent dialysis with short interdialysis interval. The author analyzed 200 cases of chronic renal failure who have received hemodialysis treatments during the 5 year period from July 1976 to June 1981 at the hemodialysis unit of the hanyang University Hospital and the following results are obtained; 1. Actual one year survival rate was much higher in thrice(87.1%) than one(35.1%) or twice(54.1%) weekly dialysis. 2. Long term(more than 6 months) complications were also more frequent in once(85.7%) or twice(70.2%) weekly treatments than in thrice(22.2%). The predominant complications were congestive heart failure, pericarditis, and infections. 3. Those who recieved three times weekly dialysis had better rehabilitation grades than the patients groups of twice or once weekly treatment. 4. Of peridialysis distressful symptoms, nausea, vomiting dizziness were less frequent in the group three times a week dialysis. In contrast, headache, hypotension, muscle cramps, and weakness were not significantly related with frequency of hemodialysis. 5. Those who voided a large amount of urine output had better survival and less frequent requirement of blood transfusions. 6. Main causes of death were due to patient poor compliance, hyperkalemia and cerebrovascular acidents. 7. Economic problems were the major cause of dialysis interruption.
