Radiofrequcy(RF) treatment has a long history, more than hundred years, for the management of chronic intractable pain of various causes. With better understanding of pain mechanism and advancement of technology, along with previous valuable experience, a simpler and safer method of delivering RF thermo coagulation to ideal sites are now available that can be expected to provide more beneficial effects to these patients with chronic disabling pain. This type of treatment will be especially helpful in aged in whom surgery is often contraindicated or highly risky due to medical problems. Here, using up-to-dated, evidence based knowledge and personal experience, authors have tried to introduce briefly the history and basic mechanism of RF technique and various clinical situations where this type of therapy is currently known to be indicated or effective in providing substantial pain relief. In summary, the RF thermocoagulation is proven to be effective way of providing significant pain relief in many chronic refractory pain states with numerous advantages such as minimal invasive, quantitative lesioning with temperature-controlled, well-circumscription of lesions, simplicity and feasibility of procedure, and most of all safety and cost-effectiveness. When it is selected based on careful investigation on type and cause of pain it can be expected to provide relatively long duration of pain relief and also to help to recover functional disabilities from such pain. However, judicious use is warranted because some painful conditions are known to be ineffective or contraindicated from this type of therapy and because there are possible serious complications, although very few. Use of latest technique of pulsed, high-frequency, low-temperatured thermocoagulation will possibly bring hope and new insights in the management of chronic intractable pain of neuropathic in nature. Further research and experience will be required before justifying this type of therapy in appling broader and more challenging situations.

Recently the incidence of intertrochanteric factures of the femur has been increasing progressively due to prolongation of average life span and increased activity. Most of intertrochanteric fractures of the femur occur in elderly patients with osteoporotic bone change and general weakness. The goal of treatment is early mobilization with immediate weight bearing to prevent the complications such as deep vein thrombosis, pulmonary embolism, pneumonia or atelectasis, and pressure sore. We have tried to assess the outcome and complications of bipolar hip prostehsis for the femoral intertrochanteric fracture in elderly patients. The twenty octogenarian patients received a bipolar hip prosthesis due to femoral intertrochanteric fractures from January 1989 to December 1994 at the Department of Orthopedic Surgery of Chonbuk National University Hospital. The results were as follows: 1. The average age of patients was 83.5 years and underlying problems are hypertension, cerebral vascular accident, pulmonary problem, diabetes mellitus, and osteoarthritis. 2. By Tronzo classification, Type III was the most common (80%) type. 3. Complications were peroneal nerve palsy, intraoperative femoral shaft fracture, postoperative stem tip fracture, dislocation and shortening. 4. Postoperative ambulation was possible at 2 weeks after surgery. 5. In elderly unstable osteoporosis patient, bipolar hemiarthroplasty can be recommended for the first treatment of intertrochanteric fracture.

We experienced a case of a primary aortoduodenal fistula, which was successfully diagnosed and repaired. This diagnosis must be considered in cases of gastrointestinal bleeding with an abdominal aortic aneurysm. If the correct diagnosis can be made promptly, surgical repair of the fistula is possible.

In order to observe the differences in fixability and stability of the acetabular cup through the differences in cup size in relation to the size of acetabular reaming, we analyzed 75 cases of porous coated acetabular cup of Harris-Galante type which be followed up more that two years. All cases were divided into two group ; the first group (On line fit :45 cases) used with acetabular cup equal in size to the last reaming size and the second group (Press fit : 30 cases) used with acetabular cup 2mm larger than the last reaming size. For initial stability, all cases were fixed with acetabular screws. Both groups were analyzed for presence of gap, change of acetabular inclination, presence of radiolucent line, degree of displacement of vertical distance, stability and clinical results. The results were as follows; 1. The average Harris hip score was improved from 55.8 points preoperatively to 90.2 points postoperatively in the first group, from 56.9 points to 91.2 points in the second group, Clinical results are excellent in 39 cases, good in 4 cases, fair in 2 cases in the first group, and excellent in 29 cases and good in 1 case in the second group. 2. The gap between the acetabular cup and acetabulum was found initially at 17 zones in the first group but no gap at final follow up. In the second group, the gap was found at 23 zones and finally remained less that 1 mm gap was found at 3 cases in zone B1. 3. No radiologic instability of acetabular cup by Martell evaluation was noted in both 1st and 2nd group. Our data suggests that initial gap between acetabular cup and acetabulum in microporous coated acetabular cup were replaced with new bone and also, radiologic stability and good clinical results could be obtained in the second group used with acetabular cup 2 mm larger than the last reaming size.

To investigate MR artifacts induced by metallic implants, scans were obtained using both the ferromagnetic Drake lip and the non ferromagnetic Yasargil clip. Scan were taken through the area of clips using geometrical phantom. The MRI was performed by spin echo technique and gradient echo technique on both 2.0T and 0.5T MR unit. The luthors evaluated the nature and differences of artifacts in each sequence and parameter. Artifacts induced by both lips were noted in the direction of frequency encoding gradient, and consisted of region of signal loss abutted in one side by survilinear region of bright signal. Geometric distortion of image was marked in the Drake clip, out was minimal in the Yasargil clip under both 2.0T and 0.5T. Artifacts were more pronounced in the gradient echo technique than those of the spin echo technique on both 2.0T and 0.5T. Although there were no differences n the nature of artifacts induced by the Drake clip among each parameter in the spin echo technique under 2.0T, artifacts were slightly more pronounced on T2 weighted image under the 0.5T field, but no differences were found in the nature of artifacts induced by the Yasargil clip in the spin echo technique under, both the 2.0T and 0.5T fields. Marked artifacts were induced through the small area of the Drake clip which were included in the scan plane, but induced artifacts were small when a small area of the Yasargil clip was included in the scan plane. It seemed likely hat artifacts were slightly more pronounced in the 2.0T than the 0.5T field in both clips, but objective evaluation of the difference was difficult, In conclusion, these results can be an essential basis for the interpretation of MR images or patents with metallic inplants.
