Dislocation of peroneal tendons are caused by forceful domifiexion of the foot accompanied by a powerful contraction of the peroneal muscles. This mechanism of injury tears the superior pemneal retinaculum and allows the tendons to snap anteriorly. It is an important, although infrequent, cause of disability of the ankle. The acute injury can be treated by immobilization in a plaster cast, but when there is chronic recurring dislocation, surgical reconstruction is necessary. Authors experienced two cases of dislocation of pemneal tendons which were treated by use of Sarmiento's and Platzgummer's(modified) operative procedures with good results.

We have experienced 11 cases of large bony defect that were treated using microsurgery since 1981. Free vascularized bone transplantation was performed in 8 of them, vascularized bone transposition in 2 cases, and free vascularized joint transplantation in the remaining 1 case. The causes of the large bony defect were primary bone tumor (4 cases), congenital pseudoarthrosis (3 cases), open comminuted fracture (2 cases), sequela of osteomyelitis (1 case), and post-traumatic ankylosis of PIP joint of second finger (1 case). As a donor, fibula was used in 8 cases, iliac crest in 1 case, rib in 1 case and in the remaining 1 case, the second M-P joint of foot was transplanted. In 9 of 11 cases, successful result was obtained and 2 cases were failed because of vascular damage following tibial lengthening in one case and infection on the grafted area in the other one. From the above data and review of articles, following conclusions were obtained. 1. Fibula is thought to be the most appropriate donor for the large bony defect in the extremity, especially in lower extremity, but the donor site must be determined according to the anatomical and physilogical condition of the patient. 2. After mechanical lengthening of the extremity, it is recommened to perform the microvascular surgery after sufficient time for the recovery of vascular damage. But further studies are required for the identification of the change in the vascular tissue following stretching and its recovery time. 3. Progression of the ossification in the epiphysis of transplanted iliac crest was observed and this finding proposed us the idea that the epiphyseal plate injury or leg length discrepancy will be able to be treated with free vascularized epiphyseal plate transplantation and the reconstruction of the destroyed joint of growing children will be possible using free vascularized joint transplantation. 4. As the technique become more popular, the free vascularized bone transplantation is being used for the reconstruction of the extremity more frequently, but it seems to be wise to restrict its indication to cases which are impossible to be treated with more simple methods such as vascularized bone transposition or pedicled bone graft.

In Korea, the metallic implant had to be supplied through import channel with many problems. KAIST succeeded in making AISI 316 LVM stainless steel within the criteria of American Society for Testing and Materials. With the animal experiment at preliminary report I, the biocompatibility in the muscle was examined. For biocompatibility test of new material, test in the bone is essential. In this animal experiment using rat tibia, the biocompatibility of the Kirschner wire of KAIST was compared with that of Zimmer. The result was as follows: 1. Tissue reaction of the Kirschner wire of KAIST was minimal to moderate. 2. Corrosion was negligible, and there was no definite difference between the KAIST and Zimmer Kirschner wires. 3. Authors observed the satisfactory biocompatibility of the KAIST Kirschner wite in bone and muscle, and concluded that the Kirschner wire of KAIST can be applied to human body without serious problems.

PURPOSE: Increasing evidence suggests that Randalls plaque contributes to the pathogenesis of urinary stone formation. The purpose of our study is to compare the incidence of the abnormal metabolic stone risk factors between the calcium stone former with papillary calcification and the calcium stone former without papillary calcification on unenhanced spiral computed tomography (CT). MATERIALS AND METHODS: A series of patients with calcium stones (n=49) underwent unenhanced spiral CT and complete metabolic evaluation after they consumed a random diet for 1 month after stone removal. Of the 49 patients, 38 patients showed papillary calcification on unenhanced spiral CT and 11 patients did not. Their blood was evaluated by using a multichannel analysis sequential multichannel autoanalyzer (SMA)-20 and PTH tests. The 24-hour urinary constituents were assayed for calcium, oxalate, citrate, total volume, phosphorus and sodium. We compared the incidence of abnormal metabolic risk factors between the two groups. Statistical analysis was performed by chi-square tests. RESULTS: The incidences of hyperuricemia were 27.3% in the patients without papillary calcification and 31.6% in the patients with papillary calcification. The incidences of hypernatriuria were 18.2% versus 42.1%, the incidences of hypercalciuria were 36.4% versus 26.3%, the incidences of hyperuricosuria were 18.2% versus 18.4%, the incidences of hyperoxaluria were zero versus 28.9%, and the incidences of hypocitraturia were 45.5% versus 44.7%, respectively. The difference between the two groups was statistically significant only for hyperoxaluria (p=0.043). CONCLUSIONS: Hyperoxaluria is the only metabolic risk factor that more frequently occurred in the patients with papillary calcification. Our date suggest that hyperoxaluria may be an important factor in the pathogenesis of papillary calcification.

PURPOSE: Imaging studies for the diagnosis of breast cancer such as ultrasonography or mammography, play an essential role; however, it is well known that they have some limitations; the low specificity of ultrasonography and the low sensitivity of mammography, especially in the dense breasts of Korean women. Recently, 99mTc-MIBI scintimammography was introduced for the detection of breast cancer, and showed acceptable results in its diagnostic accuracy. In this study, the clinical usefulness of 99mTc-MIBI scintimammography was evaluated for the determination of a better imaging study for the diagnosis of breast cancer. METHODS: This study included 75 patients with breast masses, and 3 imaging studies were performed; mammography, ultrasonography and 99mTc-MIBI scintimammography and the results compared on the basis of the pathological reports from core needle or excisional biopsies of the patients. RESULTS: From the pathological reports of 75 patients, 45 cases were confirmed as malignant and 30 as benign diseases. Based on the pathological reports, the sensitivities of mammography, ultrasonography and 99mTc-MIBI scintimammiography were 62.2, 88.9, and 86.7%, and the specificites of 3 imaging studies were 90.0, 76.7, and 90.3% respectively. The positive predictive values were 90.3, 85.1, and 92.9% and the negative predictive values were 61.4, 82.1, and 81.8%, respectively. 99mTc-MIBI mammoscintigraphy showed a comparable sensitivity to ultra-sonography, and a similar specificity to mammography, in the diagnosis of breast cancer. CONCLUSION: Clinically, as a primary imaging tool, 99mTc-MIBI mammoscintigraphy showed acceptable results in the diagnosis of breast cancer. Considering the weak points of ultrasonography and mammography, 99mTc-MIBI mammoscintigraphy would be a very useful tool in the diagnosis of breast cancer.

BACKGROUND: Functional restoration of the facial expression is necessary after facial nerve resection to treat head and neck tumors. This study was conducted to evaluate the functional outcomes of patients who underwent facial nerve cable grafting immediately after tumor resection. METHODS: Patients who underwent cable grafting from April 2007 to August 2011 were reviewed, in which a harvested branch of the sural nerve was grafted onto each facial nerve division. Twelve patients underwent facial nerve cable grafting after radical parotidectomy, total parotidectomy, or schwannoma resection, and the functional facial expression of each patient was evaluated using the Facial Nerve Grading Scale 2.0. The results were analyzed according to patient age, follow-up duration, and the use of postoperative radiation therapy. RESULTS: Among the 12 patients who were evaluated, the mean follow-up duration was 21.8 months, the mean age at the time of surgery was 42.8 years, and the mean facial expression score was 14.6 points, indicating moderate dysfunction. Facial expression scores were not influenced by age at the time of surgery, follow-up duration, or the use of postoperative radiation therapy. CONCLUSIONS: The results of this study indicate that facial nerve cable grafting using the sural nerve can restore facial expression. Although patients were provided with appropriate treatment, the survival rate for salivary gland cancer was poor. We conclude that immediate facial nerve reconstruction is a worthwhile procedure that improves quality of life by allowing the recovery of facial expression, even in patients who are older or may require radiation therapy.
