The incidence of intertrochanteric fracture of femur in young adult is relatively high in our home than other countries. But recently the incidence in elderly patient is progressively increased due to prolongation of average life span and increased activity. Various devices has been developed and the result of treatment has been improved, but the morbidity after fracture in elderly patient remains high because of poor general condition and osteoporosis. We tried to assess the availability of SHCP(sliding hip compression plate) in the intertrochanteric fracture of the osteoporotic bone by the review of the 27 cases below Singh index III that we experienced from September, 1989 to June, 1993 at the Department of Orthopedic Surgery of Chonbuk National University Hospital. The results were as follows: 1. Mean age was 68 years. Type III in Tronzo classification was most common(51.9%). Singh index II was 17 cases(63%) and grade III was 10 cases(37%). 2. In 23 cases(88.8%), anatomical reduction was performed. The bony union was gained at average 15.8 weeks. The serious complications were 1 penetration and 1 osteoarthritis of hip. 3. Satisfactory results were obtained in 88% of patients by the functional class of Clawson DK.

The need for microvascular anastomosis is on the increase for the prevention or treatment of hemodynamic stroke or planned major vessel occlusion for the treatment of complex intracranial vascular lesions or tumors. The surgical skill of the microsurgeon is the most important factor for successful microvascular anastomosis. Thus, surgical experience in the laboratory is essential. With a review of the literature, we demonstrate characteristics of several training materials for the laboratory and preclinical assessments of surgical skills.

BACKGROUND: There has been a change in the causes of aortic stenosis when comparence of rheumatioc aortic stenosis in recent year. Therefore, we studied the etiology factor of pure aortic stenosis. METHODS: The gross surgical pathologic features of the aortic valves were reviewed in 92 patients with pure aotic stenosis whom underwent aortic valve replacement at Yonsei University, Cardiovascular center between July 1989 and June 1994. RESULTS: The three most frequent causes were 1) calcification of congenital bicuspid valve in 30%, 2) degenerative calcification of aortic valve in 22%, 3) rheumatioc valvular change in 48%. The mean age at the time of aortic valve replacement for the entire series of patients was 54.4 years. The range of age was from 18 years to 77 years. Males predominated for degenerative disease and congenital bicuspid valves, but there were reversed rheumatic origin. One or more complications occured in 17% of patients undergoing operation. The surgical mortality was 3.3%. CONCLUSION: Our data suggest that more common cause of aortic stenosis is non-rheumatic disease rather than rheumatinc origin.

BACKGROUND: Total occlusion of the infrarenal abdominal aorta is a very rare disease in clinical practice. The clinical outcome may be poor unless management is attempted promptly. Surgical bypass has been recommended as the treatment of choice for these lesions. However, there was relatively high surgical mortality and morbidity associad with aorto-bifemoral bypass graft in patients with other systemic disease, especially coronary artery disease. As a result, the use of, thrombolysis with percutaneous transluminal angioplasty (PTA) has recently been extended to this disease as an alternative method to surgery. PTA is technically simpler with less morbidity and mortality than surgery.We report our experience with thrombolysis and balloon angioplasty of total aortic occlusion in 14 patients between March 1991 and December 1996. METHODS: Fourteen patients, whose mean age was 59+/-13 years (11 male, 3 female), serve as the study's patients. Aortography was introduced via transbrachial artery. The end hole multipurpose catheter with guidewire was introduced into the thrombotic portion of the total occlusion. Urokinase was infused into the thrombus through the catheter if there were no contraindications. in sysremic thrombolysis. Thrombolytic therapy was continued until the thrombi was resolved and flow was restored. Balloon dilatation was followed in residual stenotic lesions. Stents were implanted in case of suboptimal results after ballooning. RESULTS: Clinical findings were resting leg pain in 6 patients, gangrene in 5 patients, and claudication in 3 patients. The causes of aortic occlusion were thromboembolism in 4 patients and thrombosis of an atherosclerotic aorta in 10 patients. Location of obstruction was below the renal artery in all cases. The clinical outcome of interventional therapy was successful in all cases except one patients. Operative treatment was undertaken in 2 cases because they could not received thrombolytic therapy due to contraindication and complication of thrombolytic therapy (gastrointestinal bleeding). Near normal revascularization was achieved in 3 patients by thrombolytic therapy only. PTA was performed at the stenotic after thrombolytic therapy in 4 patients. Stenting were performed at the stenotic sites after balloon dilatation in another 4 patients. There was bleeding complication in one case. CONCLUSIONS: Interventional therapy such as thrombolytic therapy with PTA is an effective and safe treatment modality for abdominal aortic total occlusion in selected cases. These techniques were very useful in some high risk patients who received surgical bypass procedures.

PURPOSE: The purpose of this study was to evaluate the safety, feasibility and effectiveness of an endoluminally-placed bifurcated stent-graft (Vanguard) for the treatment of infrarenal abdominal aortic aneurysm (AAA). METHODS: Transluminal endovascular stent-graft placements were attempted in 29 patients (28 male, mean age 69+/-7 years) with AAAs involving the common iliac arteries from Aug. 1997 to Jan. 1999. Endovascular therapy was performed in the cardiac catheterization laboratory with epidural anesthesia. One side of the femoral artery was opened by surgical cutdown for the bifurcated stent-graft entry and the other side was punctured percutaneously for the straight stent-graft. Computed tomography and/or intraarterial angiography were performed during an average follow-up of 10 months (2-18 months). RESULTS: Primary success rate was 75.9% (22 of 29 patients) and the overall success rate was 79.3% with successful correction of one perigraft leak. Twenty patients (69.0%) had significant coronary artery disease. There were two technical failure cases, the one was tortuous iliac vessel with spasm, the other was disconnection of the stent-graft connecting portion. Complications related to procedure occurred in 13.8% of patients (4 of 29 patients) and two of these four patients had procedure-related mortality because of acute renal failure following contrast overdose and sepsis after operation. CONCLUSIONS: Endovascular treatment of infrarenal AAA with bifurcated stent-graft (Vanguard<0A397>) is effective, feasible and relatively safe. However, further investigation for the outcome, complication and long-term follow-up are needed.

Acute bacterial infection of bone and joint presents a real challenge to orthopedist because early diagnosis and treatment are difficult and also essential. In almost all practices, fever and erythrocyte sedimentation rate(ESR) are widely used for monitoring the course, for estimating the effectiveness of treatment, and for the recovery of such illnesses. However, interpreting body temperature is difficult and ESR is nonspecific, is not not sensitive, normalizes slowly. Otherwise, C-reactive protein(CRP) is very sensitive and normalizes fast. CRP, body temperature, and ESR were sequentially measured until a normal value was reached in twenty seven patients in whom acute osteomyelitis (17 patients), acute exacerbation of chronic osteomyelitis(4 patients), and septic arthritis(6 patients) had been diagnosed by positive bacterial culture at Kyungpook National University Hospital from June 1984 to May 1985. The results were as follows: 1. CRP normalized within 8.8 days on average. 2. Fever lasted 4.5 days on average. 3. ESR normalized within 41.6 days on average. 4. Initial mean value of CRP was 4.2 positive in acute in acute osteomyelitis and septic arthritis and 3.5 positive in acute exacerbation of chronic osteomyelitis, therefore CRP can be considered as a very sensitive indicator for early detection of acute bacterial infection of bone and joint. Also sequential CRP determination can be used for monitoring the course, for estimating the effectiveness of treatment, and for the recovery of such illnesses.
