There are many problems in treatment of intertrochanteric fractures due to osteoporosis and unstable pattern of fractures in old ages and they are different from those in young ages, for example, type of fracture, degree of osteoporosis, and general condition, ect. Anthors studied about the prognostic factors of 42 cases among 88 patients with intertrochanteric fractures, who were treated and followed up from Jan. 1982 to Dec. 1987. 1. The patients under 50 years old were mainly males(94.4%) and its chief cause of injury was traffic accident or fall down(72.2%). The cause of injury over 50 years old was slip down on ground(62.9%). 2. The osteoporosis was increased according to increased age of patients and then the unstable type of fracture was increased. In yaung patients, the unstable intertrochanteric fracture was rare despite of high violent injury. 3. The bone union of the follow-up patients was gained at average 13.8 weeks. 4. The sliding degree of lag screw was increased with unstable fracture and the incidence of metal protrusion into joint cavity was increased in the patients of eccentric fixation of lag screw into femoral head. 5. The all cases of complication were occured in osteoporotic patients over 50 years old and their causes were inadequate fixation of unstable fracture. 6. The most important factors in prognosis of intertrochanteric fractures are initial pattern of fractures, degree of osteoporosis and adequacy of reduction state(postop.).

The acute anterior cruciate ligament injury is one of the most common ligament injury of the knee joint and there are many controversies in its treatment. Warren reported that the primary repair for the acute anterior cruciate ligament injuries was good, but some had opposite oppinions. Authors studied 23 patients of actue anterior cruciate ligament injury who were treated by primary repair from January, 1982 to December, 1984. The results were as followings: 1. The most common associated injury was MCL injury and posteromedial capsular injury(13 cases; 56.5%). 2. The most common detachment site of ACL was femoral attachment(11 cases; 47.8%) . 3. A medial Hocky Stick incision was found good in repairing the combined MCL and posteromedial capsular tear with ACL injury. 4. The results were good in 74% by Cincinnati score and in 87% by objective score. It is concluded that primary repair of the acute anterior cruciate ligament tear is cosidered successful.

There are several methods available to check bone masses. One of them is Singhs index which is singlest way with grading trabecular pattern of the proximal femur on anteroposterior X-ray film and the other is recently developed Dual Photon X-ray Absorptiometry which measures bone mineral contents. Some authors proclaim that Singh's index has low accuracy, objectiveness and reproducibility. So we studied for reliability of Singh's index and correlation between Singh's index and bone mineral contents measured by Dual Photon X-ray Absorptiometry in 65 patients. There are significant differences between 3 orthopedic surgeons in interpreting Singh's index (interpersonal difference). There are significant differences between first and second interpretation out of same surgeons (intrapersonal difference). There are significant differences interpretating among interpreted Singh's indices from films of different radiological exposures in the same radiograph. There are fair correlations(0.60-0.66) between Singhs index and bone mineral density. The Singh's index was overestimated in low bone mineral density with under-exposed radiograph, but Singh's index was under-estimated in high bone mineral density with over-exposed radiograph. Singh's index can be useful in clinical application by some modification.

Two cases of synovial hemangioma have been experienced at the Department of Orthopedic surgery, Seoul National University Hospital. In the first case, synovial hemangioma about 1.5cm in diameter was found to be attached to the anterior aspect of the medial condyle of the left femur, which was excised completely with good follow-up result. In another case, cavernous hemangioma was observed diffusely invading tendon sheaths, lower one third of the tibia and also synovium of the ankle joint. Because of diffuse involvement, complete removal was not possible. After partial removal, a total 800 r Roentgen therapy was taken.

The proximal tibial osteotomy is a procedure usually employed for osteoarthritis of the knee with a predominant single compartment involvement accompanied by pain and angular deformity. It has as its objective the shift of the gravitational line of weight from an involved to a relatively uninvolved side of knee. We studied the results of proximal tibial osteotomy in 30 patients (33knees). The mean age was 55.7 years, degenerative osteoarthritis was 31 cases (93.9%) and posttraumatic osteoarthritis was 2 cases (6.1%). The results were as follows; The average distance of osteotomy between the proximal plane and distal plane was 10.3mm. The average preoperative tibiofemoral angle was varus 3.8degrees and average postoperative tibiofemoral angle was valgus 7.6 degrees. The amount of upward displacement of fibular head after proximal tibial osteotomy was from 3mm to 16mm (mean 7.5mm). The preoperative knee rating scale was 52.9 and the postoperative knee rating scale was 78. The complications of proximal tibial osteotomy were 3 cases of transient peroneal nerve palsy and 2cases of Coventry staple loosening, but the nerve palsy was completely recovered and there were no need of staple removal.

BACKGROUND: The hypereosinophilic syndrome(HES) represents a leukoproliferative process likely caused by a number of disorders, all of which are marked by sustained over-production of eosinophils. OBJECTIVES: The purposes of this study were aimed at evaluating the clinical and histopathological characteristics of HES. METHODS: The medical records and hist opathological slides of patients with HES who had skin biopsies performed in our department were reviewed. Criteria for the diagnosis of HES include (1) peripheral blood eosinophilia with eosinophil counts greater than 1,500/L for at least 6 months; (2) no evidence of parasitic, allergic, or other known causes of eosinophilia; and (3) presumptive signs and symptoms of multiple organ involvement. RESULTS: Four male and three female patients were included. HES developed in adulthood or old age (mean, 43.4 years). Because only the patients with cutaneous involvement were included, all the patients showed skin lesions. Heart, liver, stomach, nervous system, lymph nodes, and lung were involved organs in decreasing order of frequency. At the onset of HES, 40 to 80% of white blood cells were eosinophils in peripheral blood. White blood cell count and serum IgE level were elevated in all the tested patients. In six patients (85.7%), the level of serum erythrocyte sedimentation rate was elevated. Persistent hypereosinophilia (>1,500/L) was present for longer than 6 months in all patients. Stool examination and skin test for parasitic infestation all gave negative results. All the patients were not taking any medication. Histopathological examinations revealed perivascular mixed inflammatory cell infiltration; predominantly eosinophils in the stomach, liver, and nerve as well as in the skin. Interestingly, two patients who were presented with skin lesions showed the findings of eosinophilic vasculitis. In these patients, the skin lesions were consisted of Raynaud's phenomenon, digital gangrene, and several erythematous plaques. The most common cutaneous manifestations were papules and nodules on the extremities. The main treatment modality was systemic steroid. Except for one patient presented with central nervous system involvement of HES, all the patients were in a well-controlled state. In one patient with the typical clinical and hematologic features of HES, Hodgkin's disease followed. After the complete remission of Hodgkin's disease with chemotherapy, HES subsided. CONCLUSIONS: HES is a heterogenous collection of disorders marked by hypereosinophilia and organ damage. Most common cutaneous manifestations were papules and nodules on the extremities. Raynaud's phenomenon and digital gangrene can be the primary manifestation of HES in which cases cutaneous lesions showed eosinophilic vasculitis. Five patients (71%) responded well to systemic steroids. HES may be a herald of malignancy such as Hodgkin's disease. Further investigation will be mandatory ro elucidate the etiology and pathogenesis of HES.

PURPOSE: The residual intrahepatic stones with biliary strictures are difficult to remove percutaneously via T-tube tract after surgery in patients with recurrent pyogenic cholangitis. We evaluated the effectiveness of percutaneous balloon dilatation of benign biliary strictures. MATERIALS AND METHODS: The balloon dilatations with 6-12mm angioplasty balloon catheter and stone extractions were performed via a T-tube tract after surgical treatment in 15 patients with recurrent pyogenic cholangitis. The balloons were inflated for 3-4minutes under 5 atm. until disappearance of waist of the stricture site, from one to seven session. After balloon dilatation, residual stones were extracted with saline irrigation or stone basket. RESULTS: Among total 42 strictures, the balloon dilatation was succesful in 27 strictures(64.3%), partially successful in 12 strictures(28.6%), and failed in three strictures(7.1%). Single or central biliary strictures were dilated easily rather than multiple ductal strictures. Of 26 sites with residual intrahepatic stones, stone extraction was complete in 17 sites(65.4%), incomplete in seven sites(26.9%) due to impacted or large stone and acute ductal angulation, and failed in two sites(7.7%). CONCLUSION: Percutaneous balloon dilatation of benign biliary strictures is an effective procedure for extraction of residual intrahepatic stones associated with recurrent pyogenic cholangitis.

BACKGROUND: Intracoronary stent implantation is a promising modality for establishing the blood flow of complex coronary arterial stenosis. However, previous studies have demonstrated that the angiographically visible thrombus is a high risk factor for possibility of stent thrombosis. So many investigators avoided stent implantation traditionally for thrombus containing lesion because of the potency of thrombogenecity of stent. But recently, advanced rapidly growing technique for stenting and powerful antithrombotic regimens make stent thrombosis rare. Stent implantantion has already been showed a acceptable method for bailout procedure of thrombotic occlusion in patients with angioplasty for acute myocardial infarction and also effective in intimal dissection, suboptimal results and arterial recoil. Accordingly, we investigated the effectiveness of stent implantation in the presence of intracoronary thrombus. METHODS: Eighteen patients(AMI 14, Unstable angina 4) underwent PTCA & stent implantation on culprit arterial lesion in all successfully. The stent group was comprised of Palmatz-Schatz stent 10, Cordis 2, Cook 5 and Jo-Med stent 1. Stent implanted to the lesion of remained thrombus visualization on coronary angiography after PTCA. RESULTS: No major complications were developed during hospitalization in all 18 patients. In all patients no stent thrombosis have occurred within 2 weeks after stent implantation. But one patients have showed intracoronary stent thrombus persistently, so we used intracoronary urokinase infusion for 36 hours but there was no visible thrombus after modified anticoagulation and antithrombotic regimen CONCLUSIONS: We harvested good preliminary results of intracoronary stent implantation in the setting of thrombus containing lesion.
