PURPOSE: We evaluated oncologic outcomes of chondrosarcomas and analyzed the disease-free survival rate of chondrosarcomas according to the various factors. MATERIALS AND METHODS: We performed a retrospective study for the disease-free survival rate of 48 chondrosarcomas, 44 of which underwent surgical treatment and followed up more than 18 months since 1993, and in the remaining 4 cases, the patients died before 18 months after surgery. The vsariables were location, tumor volume, histologic grade, stage, age at presentation and treatment performed. The mean follow up period was 43.8 months (1-196 months). RESULTS: The overall disease-free survival rate was 77.1% at mean 43.8 month follow up. The 5 year- and 10 year disease-free survival rates were 64% and 58% respectively. The histologic grade, stage, age at presentation revealed statistical significance on disease-free survival. All 9 patients treated with extended curettage for grade 1 central chondrosarcomas revealed disease-free survival with excellent functional outcome. CONCLUSION: The disease-free survival rate of chondrosarcomas mainly depended on histologic grade, stage and age at presentation. Local recurrence and distant metastasis also revealed statistically significant differences of disease-free survival rate. Comparing to wide resection, extended curettage for low-grade central chondrosarcomas in extremities were efficient methods with similar survival rate and less functional losses and complications.

To evaluate the reproducibility of the Ambulatory Electrocardiography (AECG), we examined the consistency rates of premature beats between the baseline AECG's and the repeat AECG's in 23 patients who underwent AECG's times within 1 year. 12 patients were male and 11 patients were female. Their mean age was 48 years. (Range ; 20 years-75 years) The time interval between both AECG's was 1 month 20 days. (Range ; 1 day-9months) They did not take any antiarrhythmic druge during the observation period except 4 patients who were taking calcium channel blockers or beta receptor blockers for hypertensive heart disease or ischemic heart disease. The consistency rate of both frequency and complexity of ventricular premature beats was 52%. The consisency rate of both frequency and complexity of supraventicular premature beats was 35%. These consistency rates seemed to vary as the time interval between both AECG's differed. In the case of ventricular premature beats, the consistency rates of 1 day, 8 days and 5 months as the time interval were 100%, 38% and 14% respectively. In the case of supraventricular premature beats, the consistency rates were 50%, 25% and 29%. We concluded that the reproducility of the AECG was low and this reproducibility became lower as the time interval between both AECG's became longer and that hese facts had to be considered when the effect of the antiarrhythmic drugs was evaluated.

Many investigators have shown that computer analysis of exercise induced ST segment changes in feasible and valid. This technique should make it possible to achieve uniformity of interpretation. Though myocardial ischemic response, arrhythmia, R wave amplitude and heart rate changes are documented by CASE exactly, blood pressure change, subjective and objective signs are assessed clinicall only. Therefore, both CASE and clinical analysis are demanded for the precise interpretation of GXT. Two hundred and ten patients, aged 22-68 y/o, were evaluated for comparative analysis between CASE and clinical assessment. The following results were obtained; 1) The sensitiivity of CASE to clinical analysis is 70.2%. 2) Among the 40 cases with ST segment-positive response, 24 cases(60%) had a less than 2mm ST depression and 16 cases(40%) had a more than 2mm ST depression. 3) Among the 40 cases with ST segment-positive response, 30 cases(75%) had a increased in R wave amplitude of 2.8mm in average, while among the 153 cases with GXT-negative response, 61 cases(39.9%) had R wave increase of 1.5mm in average. 4) Increment of systolic blood pressure per MET was 5.6 mmHg. There was no significant difference by age.

It is well-known that the infection of bone and joints could produce the shortening by destroying the articuiar cartilage and growth plate, or the lengthening hy increased hlood circulation to the epiphyseal and metaphyseal regions of long bone. Since 1985, we have treated total l7 cases of children s pyogenic or tuberculous children s knee with early arthrotomy and continuous irrigation etc. and followed their long hone growth for average 53 months after surgical intervention. Five patients (group I ) were early treated within 2 weeks and twelve patients(group 3 ) were delayed to treat their knees for more than 2 weeks of symptom development. Total 11 patients out of 17 cases(64.7%) (2 cases of group 1 pyogenic arthritis, and 1 case of group l and 8 cases of group II tuberculous arthritis) revealed growth acceleration. Femoral lengthening was much more greater than that of tibial growth, and the size of patella, distal femoral and proximal tibial epiphysis which were measured by computerized digitizer were also significantly larger than that of opposite knee. The total limb length was increased hy average 7mm in 6 months, l4mm in 1 year and 3mm in 2 years after operation. These results suggest the pyogenic and tuberculous arthritis in children s knee should he treated as early as possible after symptoms developed, and followed them to trace their limh inequality for at least 2 years after surgery. That means the early arthrotomy for tuberculous knee or even in pyogenic arthritis can preserve normal articular cartilage and can also prevent the early epiphyseal closure hy infection. and can get the limh lengthening by increased blood circulation around the knee joint.

To study why the palmar capsular connections between radius and lunate remain intact in perilunate ligamentous injury of the wrist joint, and to compare the material properties of the short radiolunate, long radiolunate, and radioscaphoid region of the radioscaphocapitate ligaments (as the extrinsic ligaments) with those of the intrinsic ligaments of the previous papers, the anatomical and mechanical characteristics of those three palmar radiocarpal ligaments of twenty cadavers were measured and tested by a servo-hydraulic test machine. In spite of its small cross-sectional area (24% of short radiolunate ligament), the radioscaphoid ligament demonstrates a failure load of 58% and a stress of 260% of the short radiolunate ligament, and toughness similar to both the short and long radiolunate ligaments. This suggests that the radioscaphocapitate ligament may contribute as an initial constraint to perilunate injury. The failure load of the scapholunate ligament might be smaller than previously reported due to testing strain rate, which coupled with its short initial length may make it more vulnerable to injury at lower applied loads. The short radiolunate ligament, in spite of the largest width and cross-sectional area, has a failure load and toughness similar to the long radiolunate ligament. The material properties of short and long radiolunate ligaments may explain why the rest of the carpals persistently dislocate or fracture about lunate.

We have treated total 37 cases of femoral neck fracture in children who were under the 16 years old in age at the Catholic University Medical College since 1985, followed them for average 21 months to analyse their types of fracture and treatment, complications and prevention of complications, and obtained the following results. 1. According to the Delbet's classification, type I was 1 case, II were 18(49%), most common, III were 10 and IV were 8 cases. Their ages were average 8.2 years and boys were predominant in 27 cases. 2. Thirty-six cases were treated with open reduction and internal fixation within 1-13 days after fracture, but only one type IV was treated with closed reduction, followed by hip spica cast for 6 to 9 weeks in all. 3. The fixation devises were removed at average 8.7 months after operatio. 4. fifteen complications were observed in 11 cases(37%), that were AVN(3 cases), early physeal closure(8 cases), coxa vara(3 cases), coxa valga and limb shortening(each 1 case), and their causes were severe fracture displacement(2 cases), penetration of fixation devices to physis(8 cases), incomplete reduction and loss of initial reductio (1 case) etc, but were not correlated with their method of fracture treatment. Conclusively, the femur neck fracture in children could favorably be treated with open reduction and internal fixation to reduce their complications. Physeal early closures due to penetration of screws and pin were most common cause of complications, and their long-term follow-up should be necessary.
