The frequency of infected non-union of long bones is increased due to an increment of open fractures, and so its treatment give orthopedic surgeons a rather difficult obstacles. In treatment of twenty two cases of trouble infected non-union that we undergone from march, 1980 to decmber, 1984, we use some principles of treatment, that is, rigid osteosynthesis, autogenous cancellous bone graft and irrigation system, so we obtain the good results. The conclusion are as follows: 1. All cases were men, and they occured more commonly in young adults, 10 cases (45.5%) were in third decade. 2. The fractures of the tibia showed a high frequency of infected non-union, 17 cases (77.3%) were the fractures of the tibia. 3. All cases showed a grave comminution initially, of them 18 cases (81.8%) were open fractures. 4. The most common causative organism of an infection was staphylococcus aureus, 14 cases(63.6%), showed that organism in pus culture. 5. Using the above mentioned principles of treatment, bony union was achieved in 18 cases for average 5 months except 2 cases losting the follow-up and 2 cases undergoing the below knee amputation.

There are many procedures described for the treatment of acromioclavicular seperation but there are still controversies concerning the best management of these injuries. Thirteen cases were operated on by technique of modified Phemister method and four cases by Bosworth method, Dept. of Orthopedic Surgery, Chonbuk National University Hospital from January 1980 to December 1984. The following results were obtained. The following results were obtained. 1. This injuries is more prevalent in male (76.4%) with peak incidence in the second, third and fourth decades(76.4%). 2. The most common causes of the injuries were traffic accidents and followed by falling from the height. 3. Fifteen patients were grade 3 by Allmans classification. 4. Operative method consists of modified Phemister method (76.4%) and Bosworth method (23.6%). 5. The operative procedures in Type 2 and Type 3 are good treatment of acromioclavicular seperation.

The femoral neck fractures in children remain an unsolved problem because of lack of the optimal treatment followed by unpredictable, serious complications. Since the first trial of muscle pedicle bone graft by Judet(1962), Meyers et al(1973) refined and promoted this method for nonunion and as a primary procedure, and Baksi(1983, 1986) expanded its indication to post-traumatic avascular necrosis of the femoral head. Two cases of avascular necrosis and Two nonunion cases treated by quadratus femoris muscle pedicle bone graft at the Chonbuk National University Hospital from Jan. 1986 to Jun. 1988 were reported. The age of the patients varied from 6 to 16 years ; Follow-up ranged 6 to 29 months ; all cases were displaced transcervical fracture. In according to Ratliffs assessment, three cases showed satisfsctory results and one poor.

The dysplastic hip presents problems to the orthopedic surgeon in the reconstruction of hip using total hip prosthesis. The use of bone grafts to reconstruct the lateral acetabular bone deficiency is very popular. We investigated in 23 patients(5 cemented cup and 18 cementless cup). Sixteen patients were women and seven were men, whose average age was 42.4 years old; their average followup was 4.6 years. The average Harris hip score improved from a preoperative value of 48 points to a postoperative value of 87 points. Five cases showed radiographic loosening, in which 3 cases loosening from five cemented cup and 2 cases from cementless cup arthroplasty. Radiolucent lines were observed more frequently with cemented cups at last follow-up. Of the 23 cases, 18(78%) was successful. Postoperatively limping was a major problem because most patients in this series had unilateal disease. The grafted bone was incoporated by an average time of 7.4 months, and minor resorption was showed at last follow-up. In our series, cementless cups with autogenous bone graft noted good results than cemented cup arthroplasty.

The study was undertaken to evaluate the heat resistance by split dose hyperthermia in various time intervaland temperature. For the experiments, 96 mice were divided into 2 groups: the first, 36 mice were used to evaluatethe skine reaction of mouse tail to single dose hyperathermia, the second, 60 mice were used to evaluate heatresistance by split dose hyperthermia in variuos time intervals. The results obtained are summarized as follows;1. The ND was 101 minutes at 43degrees centigrade(C) and 24 minutes at 45degrees C. 2. For a 1degrees C increasein temperature, a half in time was required to same degree of skin reaction. 3. Heat resistance was significantlydeveloped in split dose hyperthermia at 43degrees C and 45degrees C. 4. Development, maximum and decay of heatresistance were constant regardless of change in temperature. In summary, heat resistance in split dosehyperthermia is important in study and clinical application of heat therapy in malignant disease.

Late aseptic loosening of the acetabular component following total hip arthroplasty become increasing frequently after about 10 years and has become a more severe problem both in frequency and severity than femoral component loosening. The complexity of acetabular revision depends largely on the reconstruction required to restore normal anatomy due to acetabular bone loss. The clinical and radiologic results of acetabular revision using a porocoated acetabular component fixed to the pelvis with screws were studied in 36 patients (40 hips) who had moderate or severe acetabular loss. Acetabular revision in patients whose bone stock had already been destroyed provied more formidable problems at revision surgery. The mean Harris hip score was improved 46 to 84. Bone graft union was achieved by 7.4 months and incorporated by 16 months. The graft bone resorption was noted minor degree lateral to the cup. Of 40 cases, 2 cases required re-revision of acetabular cup for identifiable failure of fixation and one was showed probable loosening. The results of the present study suggest that revision of the acetabulum with use of a hemispherical cementless component stabilized with multiple screws and morselized bone grafts filling bone defects appears to be successful in restoring bone stock and providing a stable, pain-free reconstruction.

Purpose: The goal of study was to evaluate the clinical and radiographic performance of the proximal modular cementless femoral stem for use in revision total hip arthroplasty. Material and method: Fifty seven patients (57 hips) were followed for longer than 24 months or up to 8.4 years after performing revision total hip arthroplasty with using the proximal modular cementless femoral stem between January 1997 and December 2002. The preoperative diagnosis included 45 cases of aseptic loosening, 5 cases of septic loosening (re-revision operation), 6 cases of periprosthetic fracture and 1 case of recurrent dislocation. The bone deficiencies were classified according to the Paprosky classification: there were 27 cases of Type I and II, 19 cases of Type IIIA, 9 cases of Type IIIB and 2 cases of Type IV. Results: The average Harris hip score improved from 47 to 87.6. Clinically satisfactory results were noted in 50 patients (87.7%). Radiographically, distal stable fixation was observed in 54 patients (94.7%). Intraoperative complications included two greater trochanteric fractures and two proximal femur fractures. Postoperative complications included 5 femoral stem subsidences (2hips< 5mm, 3 hips>20mm), 4 deep infections, 2 non-unions of the greater trochanter and the osteotomy site and set screw dissociation was noted in 1 case. 5 proximal component changes were done due to progressive subsidence in two cases, non-union at the osteotomy site and trochanteric displacement in two cases and set screw dissociation in one hip. For the infection cases, the proximal segment was removed and re-revised with a 2nd stage operation. (Ed note: check this.) The subsidence of the femoral stems was showed in 3 Paprosky grade IIIA cases and in 2 cases of grade IIIB or more. There was no postoperative periprosthetic fracture observed at the last follow-up. Conclusion: Revision total hip arthroplasty using the proximal modular cementless femoral stem showed good results in the face of the infection of the proximal component and deficient proximal bony support. This procedure appears to be convenient for the surgeon to correct anteversion of the femoral head and leg length discrepancy.
