258 feet of patients with flatfoot were evaluated in this paper. The incidence of flatfoot is about 0.6% of the general population. The longitudinal arch was depressed in all of our cases of flatfoot, and there have been many patients suffering from pain after some kinds of heavy work. But there were no definite correlations found between the depression of the longitudinal arch and clinical symptom. The sag in the naviculo cuneiform joint is the most common X-ray finding in this series (93%), followed by the talo-navicular sagging (27%), Degenerative arthritis of the inter-tarsal joints was frequently found after the adolescent period. The talo-navicular joint was involved in arthritic changes in 60% of the cases, the subtalar joint 46% and the naviculo-cuneiform joint 42%. The prevalence of these changes was not increasing with the increasing age, so it is poatulated that the degenerative changes begin early in adolescent period. Accessory tarsal bones were more frequently seen in patients with flatfoot than in normal population. and the neck of the talus was usually deviated inferomedially. Now that the arthriric changes are very prevalent in the triple joints, there are many cases of flatfoot that should undergo the triple arth odesis inevitably if his conservative treatment was failed.

Vnrus deformity is a common finding in patients who are candidates for toial knee replacement arthropiasty. To obtain excellent clinical results and to maintain well-aligned and stable prosthetic components in patients who have such a deformity, adequate ligament balancing as well as accurate cone.ction of bony alignment is required. But many technical problems are encountered. Especially the bony defect on the medial aspect of the tibia after adequate bone cutting and ligament imbalance with laxity in the lateral side and contracture in the medial side. Total knee replacement arthroplasty with 43 patients(56 cases) to be mcre than 10 degrees of varus of tibio-femoral angle was done by a single surgeon and reviewed retrospectively. The diagnosis was osteoarthritis in 46 cases, rheumatoid arthritis in 9 cases. The average follow up period was average 33 months(l-7 years). Preoperative varus deformity of average 13.5 degree., was corrected to valgus 6.69 degrees at last follow-up. Postoperative range of motion was 122.5 degree. And the mean knee society score improved from 24.8 to 87.2 postoperatively and the function score improved from 23.6 to 83.9 postoperatively. At self-assements, 88.2% of the patients was very satisfied or somewhat satisfied. Total knee replacement ;u1hroplasty in the patients with vaus deformity is effective procedure to corri.ct deformity and improve clini- c;1 and functional status, but long-term follow up period is required for changing alignment.

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.

PURPOSE: To analyze clinical, radiological and pathological features as well as clinical outcome after surgical treatment of patients with secondary chondrosarcoma arising from osteochondroma(tosis). MATERIALS AND METHODS: We retrospectively reviewed clinical records, radiographs, pathologic slides of 14 patients. Nine patients were male and five were female. The mean age was 34 years. The mean follow-up period was 54 months. RESULTS: All patients had a history of previous mass since childhood or puberty. Preexisted osteochondroma was single in 3 patients and multiple in 10. Remaining 1 patient had multiple osteochondromatosis with enchondromatosis. MRI clearly provided thickness of cartilage cap, which was over 2 cm except in 2 cases. Chondrosarcoma was grade 1 in all except 1 case, which was grade 2. Wide excision was performed in 10 patients, marginal excision in 3 and amputation in 1. Twelve patients were doing very well without evidence of disease. Among 3 patients with marginal excision, 1 patient had local recurrence and 1 patient died of disease. CONCLUSION: Comprehensive understanding of clinical, radiological and pathological features of secondary chondrosarcoma is warranted for accurate diagnosis. The best result can be expected with early recognition of malignant change of osteohcondroma(tosis) and wide excision.

PURPOSE: To investigate prognostic factors influencing on local recurrence, distant metastasis and event-free survival of liposarcomas. MATERIALS AND METHODS: Fifty-two patients managed for liposarcomas since 1993 were analyzed respectively in the view of prognostic influence of patient age, tumor size, location, histologic type, histologic grade, resection type, surgical margin, chemotherapy and radiation therapy on local recurrence, distant metastasis and event-free survival. The mean follow up period was 39 months. The univariate and multivariate regression analysis were performed for statistical evaluation. RESULTS: The local recurrences occurred in 11 patients (21.2%) and distant metastasis in 4 patients (8%), Event-free survival rate at 4 year follow up was 67%. In univariate analysis, histologic grade, surgical margin, chemotherapy and radiation therapy were significant prognostic factors on local recurrence (p<0.05). However, histologic grade lost its significance in muitivariate analysis. Trunk location revealed higher rate of distant metastasis than extremity location. In univariate analysis on event-free survival. histologic grade and chemotherapy were significant factors (p<0.05). No factor remained significant in multivariate analysis. CONCLUSION: Considering selection bias, positive surgical margin was negative prognostic factor on local recurrence. Liposarcomas arisen in trunk revealed higher rate of distant metastasis. There was no independent prognostic factor on event-free survival of patients with liposarcomas.

Primary hyperparathyroidism is chronic disease which exhibits variable complex of symptoms suggestive of multiple system involvement. The authors have treated a case of primary hyperparathyroidism which was caused by parathyroid adenoma. The patient, 48 years old male, has been complained of back pain and polyarthralgia for five years. Radiologically, subperiosteal resorption along the radial margin of the middle phalanges and disappearance of lamina dura were noticed. In laboratory findings, serum calcium was increased, serum phosphate was decreased and alkaline phosphatase was markedly increased. Parathyroid adenoma was excised under the diagnosis of parathyroid adenoma. Four months after removal of parathyroid adenoma, improvement was noted in clinical feature, laboratory findings and radiologic findings of bone.

Xanthoma tendinosum is a hereditary lipid storage disease marked by formation of papules or nodules in the tendon, especially the extensor tendon of the hand and feet and the Achilles tendon. Xanthoma of the Achilles tendon is a rather rare, interesting orthopaedic condition that has important ramification in internal medicine and dermatology because the lesion is associated with a specific disturbance of lipid metabolism with elevated blood cholesterol level. Author present a case of bilaterally involved Achilles tendon Xanthoma. We performed subtotal resection with gastrocnemius fascial transfer on one side and total resection with peroneus brevis tendon transfer on the other side.

This study was carried out to obtain the basic data for artificial culture of veiled lady mushroom (Dictyophora spp). The optimal conditions for the mycelial growth were 25degrees C and pH 5.0 for all isolates except the optimal temperature of 30degrees C for D. echinovolvata ASI 32002 and Phallus rugulosus . The optimal medium for Dictyophora spp. was PBA (potato bamboo sawdust extract agar) medium. The strain ASI 32002, D. echinovolvata , grew faster than. D. indusiata ASI 32003 and Phallus rugulosus ASI 25007 on the medium. Carbon sources such as glucose, maltose and inuline were favorable for stimulating a mycelial growth of the two strains of ASI 32002 and ASI 32003. Asparagine and glutamine appeared to be favorable to the strain ASI 32002 and ASI 32003, where as alanine, one of nitrogen source also favorable to the strain ASI 32002. The optimum C/N ratio of the two isolates of ASI 32002 and ASI 32003 was about 25 : 1 when 2% glucose as carbon source was mixed with the basal medium. While, in the case of 4% as carbon source, the optimum C/N ratio was about 30 : 1.
