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.

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.

Despite the continually improving results of total knee arthroplasty, infection remains the most debilitating complication. The treatments of infected total knee arthroplasty were variable, but initially we removed infected implants and inserted antibiotic containing cemented spacer. Postoperatively, patients were mobilized in a 30 knee flexion state and treated with parenteral antibiotics. After control of infection was clinically and radiologically determined, we inserted PCL substitute total knee prosthesis. Five days postoperatively, patient began touch down standing exercise. We observed two cases in whom infected total knee arthroplasty had been salvaged successfully with two-stage implantation using cement spacers containing antibiotics.

Despite continually improving results of total hip arthroplasty, infection remains the major debilitating complication. The treatments of infected total hip arthroplasty were variable. but initially we removed infected implants and inserted antibiotic containing cemented spacer so called PRSTALAC to prevent scar contracture and disuse osteoporosis. After 6 weeks later, control of infection was clinically and radiologically determined, we inserted new prosthesis with cement. Three weeks postoperatively, patient began touch down standing exercise. We observed infected total hip patient in whom hip had been salvaged successfuily with twostage implantation using so called "" PROSTALAC "" which was made with Moore stem.

Eosinophilic granuloma, Hand-Schuller-Christian and Abt-Letterer-Siewe syndrome are known to be the same disease entity involving the reticulohistiocytic system of the body, although their clinical manifestations are different. So they were included under the term of Histiocytosis X and this concept has been generally accepted. The authors have experienced one case of Hand-Schuller-Christian disease and that of eosinophilic granuloma. The former was a 23 years old man with complaints of exophthalmos, polyuria and a tender palpable mass on the right parietal area and in the latter a soft pulastile mase located on the left parietal area in a 3 year old boy. There was no neurological deficits on their admission. We managed them with radiation and steroid therapy following surgical curettage.

BACKGROUND: Papillary thyroid cancer has a high frequency of lymph-node metastasis, but the methods for detecting and treating of lymph-node metastases remains controversial. We reviewed clinical analyses for lymph-node metastases. METHODS: Were retrospectively reviewed charts of 120 patients with papillary thyroid cancer who were treated from July 1994 to February 1997. Clinical aspects and the relationship between age, sex, tumor size, extracapsular invasion, multicentricity of the tumor and lymphadenopathy and the rate of lymph-node metastasis were investigated. RESULTS: Modified neck dissection was done in 97 patients, and lymph node metastases were detected in 72 patients (74.2%). Lymph-node meatastases were detected in 3 patients during routine central compartment neck dissection. The overall lymph-node metastasis was 62.5% (75 of 120). The mean number of metastastic nodes was 5.67, and the most frequent site was level VI. Lymph-node metastases were more frequent at a young age and for large sized tumors, extracapsular invasion and preoperatively palpable lymphadenopathy. CONCLUSIONS: The lymph-node metastatic rate is high for preoperatively palpable lymph node, tumor sizes over 4 cm, and extracapsular invasion (p<0.05). To reduce the recurrence rate, the surgeon shoud do a modified neck dissection on such above patients.
