There are several considerations in performing free vascularized fibular graft for the treatment of the large bone defect, e.g., bone fixation, additional bone graft, and management of complication. Authors have analyzed 25 cases treated with free vascularized fibular graft at Holy Family Hospital between Jun. 1985 and Dec. 1994. The mean follow up was 27.4 months The results were as follows: 1. The causes of the defect were traumatic defect with infection of 16 cases, bone tumor of 4 cases, congenital pseudoarthrosis of tibia of 3 cases and osteomyelitis of 2 cases. 2. Hypertrophy of the graft was more common in the lower extremity and in the patient under the age of 15. 3. Nonunion of graft occurred in 4 cases(16%). These cases were fixed with screws and/or pin ini tially and subsequently treated with rigid internal fixation. 4. Stress fracture of graft occurred in 3 cases(12%). Two cases of them were treated with internal fixation. 5. Additional bone graft were performed in 6 cases(24%), among 17 cases who had bone defect of lower extremity in adult. In conclusion, authors emphasize that rigid internal fixation and additional bone graft in performing free vascularized fibular graft are recommended for obtaining early solid bony union and achieving early rehabilitation.

Incidence of non-contiguous multiple spine fracture was increased from 3.2%~4.5% at 1960th and 70th to 5.7% ~23.8% at 80th and 90th. But there is no reports in Korea which has high incidence of traffic and industrial accidents. In 345 consecutive patients with acute spine fracture, we found that 43 patients (12.5%) had multiple non-contiguous spine fractures. At the 43 patients studies 37 (87.4%) sustained fractures at 2 levels while 6 had more than 3 levels of injury, 26 were injured by fall from heights, 27 (62.8%) had 2.33 associated injuries on an average, and 12 (27.9%) had a neurologic deficit. There are five patterns account for 26 (50%) of the total number of patients. In 19 patients (44.2%), there was a mean 29.3 days delay (from 3 to 233 days) in diagnosis of the minor lesions. In 19 delay diagnosed minor lesions, it confirmed by bone scan in 12 patinets(63.6%). Two patients died within 24 hours after accident, and 41 patients (41 major and 50 minor fractures) were treated in our hospital. Among them, 21 (51.2%) needed modification of treatment by the presence of non-con- tiguous multiple spine fractures. According to above findings, the physician must be aware of the possible noncontiguous multiple spine fractures when examine and treat the patients with spine fracture.

Pfeiffer syndrome, an unusual type of acrocephalosyndactyly, is a complex of associated malformations, first described by Pfeiffer in 1964. In addition to the common head and face anomalies seen in other acrocephalosyndactylies, its characteristics are broad thumbs and big toes, minimal syndactyly and normal intelligence. It is inherited in autosomal dominant pattern and shows various clinical features. The author's case was a 7-year old boy, who had been managed since birth for bilateral congenital resistant clubfeet including cast correction for six months and two operations. At present he represents not only the common features described above but also some unique features, e.g. pectus excavatum, posterior dislocation of both elbows, mild genu valgum, metatarsus adductus and complex malalignment of carpal and tarsal bones. To our knowledge, there is no report on Pfeiffer syndrome in Korea. The authors report a case of Pfeiffer syndrome with review of literatures.

BACKGROUND: Xenologous or synthetic graft materials are commonly used as an alternative for autografts for guided bone regeneration. The purpose of this study was to evaluate effectiveness of carbonate apatite on the critical-size bone defect of rat's calvarium. METHODS: Thirty-six critical-size defects were created on 18 adult male Sprague-Dawley rat calvaria under general anesthesia. Calvarial bones were grinded with 8 mm in daimeter bilaterally and then filled with (1) no grafts (control, n = 10 defects), (2) bovine bone mineral (Bio-Oss®, Geistlich Pharma Ag. Swiss, n = 11 defects), and (3) hydroxyapatite (Bongros®, Bio@ Inc., Seongnam, Korea, n = 15 defects). At 4 and 8 weeks after surgery, the rats were sacrificed and all samples were processed for histological and histomorphometric analysis. RESULTS: At 4 weeks after surgery, group 3 (42.90 ± 9.33 %) showed a significant difference (p < 0.05) compared to the control (30.50 ± 6.05 %) and group 2 (28.53 ± 8.62 %). At 8 weeks after surgery, group 1 (50.21 ± 6.23 %), group 2 (54.12 ± 10.54 %), and group 3 (50.92 ± 6.05 %) showed no significant difference in the new bone formation. CONCLUSIONS: Bongros®-HA was thought to be the available material for regenerating the new bone formation.

PURPOSE: Patients requiring urethral reconstruction due to failed hypospadias repairs present a considerable technical challenge. Herein we report the experience of redo urethroplasties for complicated recurrent hypospadias. MATERIALS AND METHODS: From 1987 to 1997, we performed redo urethroplasty in 11 cases with complicated recurrent hypospadias. Types of recurrent hypospadias were coronal (1 case), distal shaft (4 cases), mid-shaft (1 case), and penoscrotal (5 cases) hypospadias. The interval between the last operation and redo operation was distributed from 8 months to 5 years. We analysed preoperative status, operative methods and their complications retrospectively. RESULTS: We performed urethroplasties using scrotal skin flap or buccal mucosal graft in only 2 cases. In spite of a paucity of usable penile skin, we performed urethroplasties with maximal use of remaining penile skin. Mathieu method was used in one case with coronal type. Mustarde operation was used in 4 cases with distal shaft hypospadias. And in 5 cases with penoscrotal type, we used Thiersch-Duplay method. Six of 11 patients had complications such as urethrocutaneous fistulas (4 cases) or recurrent hypospadias (2 cases) which were managed successfully later. CONCLUSIONS: Urethroplasty using penile skin maximally such as Mathieu, Mustarde, or Thiersch-Duplay methods appears to achieve success in patient with recurrent hypospadias subsequent to previous failed repairs.

Renal cell carcinoma takes up 85 per cent of primary malignant renal tumors. It frequently metastasizes to the adrenal gland, lung, bone, liver and nephrectomy site but rarely to the head and neck area. When metastasizes to head and neck area, it involves the gingiva, tongue, palate, parotid gland, uvula, mandible, and lip. When tumors are found in the salivary gland consisting of clear cells, it is impartant to carry out differential diagnosis of various primary tumors with clear cell and metastatic renal cell carcinoma. Patients' medical history, review of system, and pathologic findings would be helpful factors in the differential diagnosis. In this paper, we report on a case of renal cell carcinoma which had metastasized to the psubmandibular gland after a radical nephrectomy.

PURPOSE: Tetanus is difficult for emergency physician to diagnosis at an early stage because of its low incidence and atypical initial clinical features. Therefore, we reviewed the clinical features of 54 tetanus cases and attempted to identify factors associated with prognosis in order to improve early diagnosis and treatment. METHODS: We carried out a retrospective chart review of 54 adult tetanus patients who presented to the ED of Chonnam National University Hospital between January 1996 and December 2005. We collected information on demographics, SAPS II score, clinical feature, course of infection and prognosis. We divided the patients to two groups according to the survival and compared their data statistically. RESULTS: Fifty four patients, 33 men and 21 women, were included in the study. The mean age was 50.97+/-15.95. The most common initial diagnosis in ED were electrolyte imbalance (n=15), neck and facial dystonia (n=9). The mean incubation period was 10.27+/-6.47 days. The initial SPAS II score 17.29+/-8.45 and the Wood score was 3.12 +/-1.47. Most commonly symptom was dyspnea and dysarthria. Twenty one patients were supported by mechanical ventilation, and the duration of mechanical ventilation was 5.92+/-4.52 days. On multivariate logistic regression analysis, four variables were found to be associated with the prognosis: incubation period, Wood score, Time interval from initial symptom to mechanical ventilation, initial SAPS II. CONCLUSION: Four variables correlated well with the prognosis: Incubation period, Wood score, Time interval from initial symptom to mechanical ventilation, initial SAPS II score.

We investigated the comparative effect of magnesium and thiosulfate on the calcium oxalate crystallization. Magnesium is a strong inhibitor of calcium oxalate crystallization and it is sported to inhibit calcium phophate by about 20%. Even if it's mechanism is not clearly known, thiosulfat can resolve 250~100,000 times more than other calcium salts when it is combined with calcium. Wistar rats were fed by 1.0% ethylene glycol (EG) mixed with water. 500mg of magnesium oxide (MgO) per 100gm chows and 10mMo1 of S2O3 per 100gm chows were provided by oral intake respectively. Forty eight wistar rats were divided into following 6 groups. Each group has equal 8 wistar rats; A group (normal chow and water), B group (normal chow and 1%EG), C group (MgO and 1%EG), D group (MgO and water), E group (S2O3 and 1%EG), and F group (S2O3 and water). First, we examined calcium oxalate crystallization on bladder aspiration urine for 6 groups before the experiment and every week for 4 weeks after the experiment. Second, we also examined the degree of formation of calcium oxalate crystallization in renal tissue under polarizing microscope. Calcium oxalate crystallization was found in all 8 wistar rats in B group while it was not round in A, D, F group. Calcium oxalate crystallization was also found in one out of 8 wistar rats in C group, and 5 out of 8 wistar rats in E group. In conclusion, we believe that both MgO and sodium thiosulfate are effective in preventing calcium oxalate stone, and we also believe MgO is more elective than sodium thiosulfate. We think that further researches on administrating methods, the side effects and dosage of these two agents in human are necessary.

MRI findings of extramedullary hematopoiesis of the spleen have not been described in the literature. Wereport the MRI features of this condition, as seen in two patients and confirmed by fine needle biopsy. Threesmall masses(< or =3cm) were isointense on T1WI, hyperintense on T2WI, and enhanced after the injection of gadolinium.Two 6cm-sized masses were hypointense on both T1WI and T2WI, and showed no contrast enhancement.
