Recently, tuberculosis of bone and joint is decreased with good nutrition and environment, development of preventive medicine and improvement of treatment regimen. But it is still one of the common inflammatory diseases in Korea, and must be considered in the differential diagnosis of common orthopedic complaints. There are few reports on extraspinal tuberculosis of bone and joint. Forty one cases of extraspinal tuberculosis of bone and joint were studied in our department from January 1988 to August 1993. The results were as follows; l. Extraspinal tuberculosis of bone and joint were 41 cases (39 patients, 27.8% of 147 tuberculosis of bone and joint including spine). 2. The proportion of children and young adults was 56%, hips were involved in 11 cases, knee joints in 8 cases, ankle joints in 6 cases, feet in 6 cases and elbow joints in 5 cases. 3. Coexisting pulmonary tuberculosis was found in 19 patients and active lesion in 15 patients. 4. Confirmative diagnosis could be made by smear and culture of the lesion or pathologic findings or recently available polymerase chain reaction(PCR) method. 5. Various treatment, such as antituberculous medication, external immobilization, synovectomy, curettage and bone graft, arthrodesis, had been carried out. 6. Reactivation of other site was found in 7.3%(3 cases) and resistant tendency was found in 9.7%(4 cases).

Even though some authors have reported on the advantages of early total correction of complex heart disease, for low birth weight premature neonates, most surgeons prefer a multi-step approach to early total correction due to the many problems, such as the technical problems, the cardiopulmonary bypass management and etc. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,250 gram premature neonate.

High tibial osteotomy is a useful procedure in the treatment of early stage osteoarthritis of the knee which is confined to the medial compartment. But long term follow-up study of high tibial osteotomy has not been provided yet and its prerequisite for a successful result still remains unrevealed. Since the osteoarthritis can progress after the osteotomy, it may result in the loss of correction and recurrence of pain and require conversion to total knee replacement arthroplasty. We studied clinically and radiologically the long term result of high tibial osteotomy in 11 patients(16 knees) who had been treated at the Department of Orthopaedic surgery of Seoul Paik Hospital during the period from January, 1978 to May, 1989, and follow-up for longer than 4 years. Preoperative mean varus angle was 6.4 degrees and immediate postoperative mean valgus angle was 8.6 degrees and final mean valgus angle was 4.7 degrees. The average loss of correction angle was 3.9 degrees. At 2-year follow-up, the results of 16 knees were as follows; excellent in six knees, good in seven knees. The final results at average 7.2-year follow-up were excellent in four knees, good in six knees and one knee was converted to total knee replacement arthroplasty. The results showed deterioration of clinical results and loss of correction with time after osteotomy. However, in more than half of the cases the results were good or excellent at the final follow-up, We, therefore, conclude that high tibial osteotomy is still a useful procedure in osteoarthritis of the knee if performed with a precise surgical technique and an adequate overcorrection more than 10 degrees.

The mortality and morbidity of peritrochanteric fractures in the elderly are great due to preexisting diseases, the osteoporosis, and poor general conditions. Since the complications sometimes lead to death, it is utmost important to reduce the complications and to prevent them. Authors had experienced 42 peritrochanteric fractures over 65 years old from January, 1988 to December, 1992. Age incidence was distributed from 65 to 93 years. The sites of fractures were 17 femoral neck, 24 intertrochanteric, 1 subtrochanteric. The mortality at postoperative 6 months was 10.2%. The postoperative complications were 6 cardiovascular diseases, 3 pneunonia, 3 pressure sore etc. The results according to interval between injury and operation were not significant, but reducing risk factors following check-up of general conditions was significant. It was necessary in treatment of elderly peritrochanteric fractures to check the general conditions, to reduce risk factors, to choose appropriate method of operation and anesthesia, and to operate as soon as possible by experienced surgeon. Postoperative early ambulation was also significant at good results. The percutaneous pinning under local anesthesia was an recommendable method in patients with severely poor general conditions.

PURPOSE: The purpose of this study was to investigate the diametral tensile strength of polymer-based temporary crown and fixed partial denture (FPD) materials, and the change of the diametral tensile strength with time. MATERIAL AND METHODS: One monomethacrylate-based temporary crown and FPD material (Trim) and three dimethacrylate-based ones (Protemp 3 Garant, Temphase, Luxtemp) were investigated. 20 specimens (the empty set 4 mm x 6 mm) were fabricated and randomly divided into two groups (Group I: Immediately, Group II: 1 hour) according to the measurement time after completion of mixing. Universal Testing Machine was used to load the specimens at a cross-head speed of 0.5 mm/min. The data were analyzed using one-way ANOVA, the multiple comparison Scheffe test and independent sample t test (alpha = 0.05). RESULTS: Trim showed severe permanent deformation without an obvious fracture during loading at both times. There were statistically significant differences among the dimethacrylate-based materials. The dimethacrylate-based materials presented an increase in strength from 5 minutes to 1 hour and were as follows: Protemp 3 Garant (23.16 - 37.6 MPa), Temphase (22.27 - 28.08 MPa), Luxatemp (14.46 - 20.59 MPa). Protemp 3 Garant showed the highest value. CONCLUSION: The dimethacrylate-based temporary materials tested were stronger in diametral tensile strength than the monomethacrylate-based one. The diametral tensile strength of the materials investigated increased with time.

STATEMENT OF PROBLEM: Recently, resin cements have become more widely used and have been accepted as prominent luting cements. Current resin cements exhibit less microleakage than conventional luting cements. However, the constant contact with water and exposure to occlusal forces increase microleakage even in resin cements inevitably. Most bonding resins have been modified to contain a hydrophilic resin such as 2-hydroxyethylmethacrylate (HEMA) to overcome some of the problems associated with the hydrophobic nature of bonding resins. By virtue of these modifications, bonding resins absorb a significant amount of water, and there may also be significant stresses at bonding interfaces, which may adversely affect the longevity of restorations. Therefore the reinforcement of water stability of resin cement is indispensable in future study. PURPOSE: This study was conducted to examine the influence of water retention on microleakage of two resin cements over the period of 6 months. MATERIALS AND METHODS: 32 ex acted human teeth were used to test the microleakage of a single full veneer crown. Two resin cements with different components and adhesive properties - Panavia F (Kuraray Co., Osaka, Japan) and Super-Bond C&B (Sun Medical Co., Kyoto, Japan)- were investigated. The storage medium was the physiological saline solution changed every week for 1 month, 3 months, and 6 months. One group was tested after storage for 1 day. At the end of the each storage period, all specimens were exposed to thermocycling from 5.C to 55.C of 500 cycles and chewing simulation of 50,000 cycles, and then stained with 50% silver nitrate solution. The linear penetration of microleakage was measured using a stereoscopic microscope at x 40 magnification and a digital traveling micrometer with an accuracy of +/-3 um. Values were analyzed using two-way ANOVA test, Duncan's multiple range tests (DMRT). RESULTS: Statistically significant difference of microleakage was shown in the 3-month group compared with the 1-day or 1-month group in bot systems (p<0.05) and there were statistically significant differences in microleakage between the 3-month group and the 6-month group in both systems (p<0.05). The two systems showed different tendency in the course of increased microleakage during 3 months. In Panavia F, microleakage increased slowly throughout the periods. In Super-Bond C&B, there was no significant increase of microleakage for 1 month, but there was statistically significant increase of microleakage for the next 2 months. For the mean microleakage for each period, in the 3-month group, microleakage of Super-Bond C&B was significantly greater than that of Panavia F. On the other hand, in the 6-month group, microleakage of Panavia F was significantly greater than that of Super-Bond C&B (p<0.05). CONCLUSION: Within the limitation of this study, water retention of two different bonding systems influence microleakage of resin cements. Further studies with the longer observation periods in viro are required in order to investigate water stabilty and the bonding durability of the resin cement.
