Brown tumor is tumor like lesion resulted from hyperparathyroidism, and it has been rarely reported recently. We evaluated a 29-year-old woman who had brown tumor on proximal humerus caused by primary hyperparathyroidism. She first had presented pain and swelling over the upper arm, and was suspected as giant cell tumor in biopsy combined with hyperparathyroidism. Wide marginal excision and tumor prosthesis were performed. However, it was confirmed as brown tumor resulted from parathyroid adenoma according to laboratory findings and radioactive isotopes image, and surgical excision of adenoma relieved clinical symptoms. We report this case with a review of literatures.
After the resection of oral tumor, defected maxillofacial structure caused functional difficulties including phonetics, mastication and esthetic aspects. In this cases, implant retained prosthesis can contribute to the functional enhancement. Regardless of the success rate in grafted bone, however, the soft tissue usually had a shape which was susceptible to inflammation. Moreover, infected graft bone presented rapid destruction. For success of the prosthetic treatment, adequate soft tissue treatment and frequent recall check are the essential factors to the successful implant prognosis.

Purpose: Tumor infiltration around the knee joint or skip metastasis, repeated infection sequelae after tumor prosthesis implantation, regional recurrence, and mechanical failure of the megaprosthesis might require combined distal femur and proximal tibia replacement (CFTR). Among the aforementioned situations, there are few reports on the indication, complications, and implant survival of CFTR in temporarily arthrodesed patients who had a massive bony defect on either side of the knee joint to control infection. Materials and Methods: Thirty-four CFTR patients were reviewed retrospectively and 13 temporary arthrodesed cases switched to CFTR were extracted. All 13 cases had undergone a massive bony resection on either side of the knee joint and temporary arthrodesis state to control the repeated infection. This paper describes the diagnosis, tumor location, number of operations until CFTR, duration from the index operation to CFTR, survival of CFTR, complications, and Musculoskeletal Tumor Society (MSTS) score. Results: According to Kaplan-Meier plot, the 5- and 10-year survival of CFTR was 69.0%±12.8%, 46.0%±20.7%, respectively. Six (46.2%) of the 13 cases had major complications. Three cases underwent removal of the prosthesis and were converted to arthrodesis due to infection. Two cases underwent partial change of the implant due to loosening and periprosthetic fracture. The remaining case with a deep infection was resolved after extensive debridement. At the final follow-up, the average MSTS score of 10 cases with CFTR was 24.6 (21-27). In contrast, the MSTS score of 3 arthrodesis cases with failed CFTR was 12.3 (12-13). The average range of motion of the 10 CFTR cases was 67° (0°-100°). The mean extension lag of 10 cases was 48° (20°-80°). Conclusion: Although the complication rates is substantial, conversion of an arthrodesed knee to a mobile joint using CFTR in a patient who had a massive bony defect on either side of the knee joint to control infection should be considered. The patient's functional outcome was different from the arthrodesed one. For successful conversion to a mobile joint, thorough the eradication of scar tissue and creating sufficient space for the tumor prosthesis to flex the knee joint up to 60° to 70° without soft tissue tension.

Purpose: We studied to decide the operative indication of the metastatic tumor in pelvis according to the oncologic results, the Eastern Cooperative Oncologic Group (ECOG) performance status and complication. Materials and methods: From May 1994 to May 2003, 9 patients who were performed on palliative treatment and 10 paitents on operative treatment due to metastatic tumor of pelvic bone were investigated. On palliative/operative group, the mean age of patients was 57.6/48.0 years old and the ratio of male to female was 5:4/7:3. Primary origins were 3 cases from kidney, 3 from cervix and 2 of lung, 2 of myeloma, 2 of Non-Hodgkin's Lymphoma, and 1 from breast, bladder, testis, prostate, stomach, liver and retroperitoneal leimyosarcoma respectively. The palliative treatment was performed in 5 cases with radiotherapy, 1 with chemotherapy, 2 with combined chemo-radiotherapy and 1 with percutaneous cementation. The operative methods were 1 case of bone cement insertion after curettage, 2 of Girdlestone with internal hemipelvectomy and 7 of reconstruction after wide excision. Reconstructions were done.: 1 case of bone cementation, 5 of autograft prosthesis composite with irradiation or pastuerization and 1 of saddle prosthesis. We have observed the oncologic results, the ECOG performance status and complication. Results: The oncologic results of palliative/operative groups are NED 0/1, AWD 2/6, DOC 1/2 and DOD 6/1. The ECOG performance status was changed from 1.5 into 4.3 in palliative group and from 2.6 into 2.2 in operative group. The complications were 3 cases of the prosthesis failure and 2 of infection. Conclusion: The indication of operation of metastatic pelvic tumor is decided in consideration of the patient's condition, the grade of malignancy in primary tumor and the life expectancy.

A new method of limb sparing by resection, extracorporeal irradiation and reimplantation has several theoretical advantages. This method preserves the mobility of a joint and avoids the problem of loosening or breakage of tumor prosthesis. This study involved using extracorporeal irradiated autogenous joint transplantation for reconstruction after en bloc resection, and observed the periods of functional union and histological changes in irradiated tissue of the knee joint. This study also aimed to clarify whether the degeneration of articular cartilage is induced in rabbits by a single 50Gy dose of irradiation at the knee joint. Twenty New Zealand rabbits about three kilograms were randomized into two groups of 10 rabbits each. In group 1, as control, we resected the knee joint followed by reimplantation without irradiation. Group 2 received extracorporeal irradiation on the resected knee joint followed by reimplantation. Following are the results of these observations. The osteotomy site showed external callus formation in the roentgenographic finding eight weeks after reimplantation. There was marked degenerative changes in the collagen fiber of the irradiated anterior cruciate ligament and meniscus during the fourth week, but new blood-vessel formation was observed in the vicinity. There was degenerative changes in the collagen fiber of articular cartilage treated extracorporeal irradiation at four and eight weeks in the scanning electron micrographic findings. These findings was in contrast to those of subchondral bone which showed decreased cellularity and empty lacuna at four and eight weeks. Autoradiography demonstrated active [$^3H$]uridine incorporation by irradiated chondrocyte at eight weeks after reimplantation. These results indicate that when destruction of the articular cartilage and soft tissue of the knee joint is not severe, extracorporeal irradiation and reimplantation can be used with several advantage in maintaining movement of the joint while avoiding problems of tumor prosthesis and rejection, and therefore extracorporeal irradiated autogenous joint transplantation can be used as a limb-sparing procedure for temporary biological spacer in the childhood bone tumor around the knee.

Purpose: Recycling extracorporeal irradiated autograft is used as one of the reconstruction methods after limb salvage with malignant bone tumor. However, there were some problems such as joint instability, progressive arthritis, insufficient joint resection margin were found after intraarticular recycling autograft. Thus, we carried out a research in order to investigate the results of recycling total joint autotransplantation after extracorporeal irradiation that could resolve the problems. Materials and Methods: There were five cases of patients who were diagnosed as osteosarcom around the knee joint and underwent same operation from June 1997 to Feb 2006. All patients had been evaluated from 93 to 105 months (mean 100 months) and their mean age was 21.6. Results: The roentgenographic union of junctional sites began at 15.6 months (9~40 months) postoperatively. As regards to the orthopaedic functional results, we used the criteria of Ennecking et al. Overall mean functional result was 71.6%. Complication such as epiphyseal collapse (three cases) and joint instability (five cases) were noted respectively. In all the cases, tumor prosthesis was used to replace the knee joint. Conclusion: Because recycling total joint autotransplantation after extracorporeal irradiation does not prevent joint instability and progressive arthritis, tumor prosthesis is recommended in young adult.

Purpose: In this report we are going to discuss about the functional evaluation and the outcome of treatment of metastatic tumor in the lower extremities treated with tumor prosthetic arthroplasty. Materials and Methods: This report is based on nine patients diagnosed as a metastatic tumor and treated by tumor prosthetic arthroplasty, from June 1998 to December 2001. Age of the patients ranged from 49 to 63 with the average of 56.3. The average follow up period was 23.4 months. Two patients had lung cancer, three had breast cancer, two had renal cancer, one colon cancer, and one had multiple myeloma. All these were primary cancers. The site of metastasis were six in proximal femur, two in distal femur, and one in proximal tibia. Tumor excision was performed after biopsy in following the principle of primary tumor management. Excision with wide surgical margin was tried as possible could. Six cases were treated with tumor prosthesis, and the other three cases were reconstructed with bone cement and arthroplasty. Results: The functional evaluation in the extremities at the last follow up was performed on Enneking evaluation score with 6 categories. The highest scored 26, and the lowest scored 10, with an average of 19.5. A case in which the patient died 15 days after the operation was excluded from the evaluation. Among the categories, emotional acceptance to postoperative function and pain relief were highly scored. At the final follow up, seven patients survived, and one colon cancer patient died 68 days after operation. Conclusion: Metastatic tumor occurring in joints of lower extremities could be treated in accordance to the treatment principle of primary tumor. By insertion of tumor prosthesis, we can get satisfactory results of function in the lower extremity and pain relief especially. So, this aspect of medical favor must be considered in treating patients.

Purpose : In patients having malignant and aggressive bone tumors around knee joint requiring amputation, segmental resection and rotationplasty were performed and the clinical results were analyzed. Materials and Methods : Twenty-six patients underwent segmental resection and rotationplasty between February 1988 and June 1994, because limb salvage with tumor prosthesis after removal of tumor was impossible. The mean follow-up of malignant tumors was 57(6~120) months and the average age of patients was 21.4(5~37) years old. Out of 26 patients, there were 18 osteosarcoma(${\geq}$stage IIB), 2 synovial sarcoma, and 6 giant cell tumor. Results : Clinical results were evaluated by the Shriner's rating system. Four patients were excluded due to death or amputation and remaining 22 patients were included for assessment. Eighteen patients had excellent result, 3 good, and 1 fair. Range of motion of ankle joint was -11(dorsiflexion)~80(plantarflexion) degrees and daily walking activity with prosthesis was possible. Local recurrence developed in 2 patients and distant metastasis in 10. Early complications had 3 thrombosis and 1 sepsis, and late complications had 6 nonunion, 2 malrotation and 1 stiffness of ankle joint. Conclusion : Rotationplasty which is functionally excellent may serve as an effective partial limb salvage procedure, especially in patients less than 10 years old that lower extremity discrepancy or loosening tumor prosthesis due to enlargement of medullary cavity are anticipated or amputation is inevitable for wide resection margin.

Purpose: To evaluate clinical results of the tumor prosthetic replacement for pathologic fracture of the proximal femur with extensive bony destruction due to metastatic bone tumors. Materials and Methods: From 2005 October to 2006 October, resection of proximal femur and tumor prosthesis replacement was performed for metastatic bone tumors extensively involving trochanteric area in 6 patients. The mean age of overall patients was 61(range, 48~77). Mean clinical follow up was 10.5 months (range, 6~16). Primary tumor consisted with multiple myeloma in 2 patients, lung cancer in 1, breast cancer in 1, transitional cell carcinoma of the renal pelvis in 1, unknown origin in 1 patient. $MUTARS^{(R)}$ proximal femur (Implantcast, Munster, Germany) were used in all cases. The functional evaluation in the lower extremities was performed with Musculoskeletal Tumor Society 1993 scores. The degree of pain relief after surgical treatment was assessed with Visual Analogue Scale (VAS). Results: At the final follow up, all of the patients survived. The mean lower extremities functional score of Musculoskeletal Tumor Society 1993 was 17.8(59.3%)(range, 12~25). VAS was improved to 2.5 from 8.5 after the surgical treatment. Ambulation was encouraged as soon as possible and mean duration after surgery for ambulation was 7.3(range, 3~16) days. Post-operatively, there was no surgical infection, periprosthetic fracture or loosening. Dislocation occurred in one out of six cases. Conclusion: Resection of proximal femur and tumor prosthesis replacement for metastatic bone tumors around proximal femur extensively involving trochanteric area seems to be safe procedure in view of post-operative complication, and effective for functional restoration as well as pain relief. Thus, it is accordant to the treatment principle of the metastatic bone tumors.
Mandibular defects lead to severe deformation and functional deficiency. Vascularized osteocutaneous tissue has been widely used to reconstruct the mandible. However, it is technically challenging to shape this type of grafts in such a manner that they resemble the configuration of the mandible. A 48-year-old female patient who underwent anterolateral thigh (ALT) flap coverage after a tongue cancer excision was diagnosed with a tumor recurrence during the follow-up. A wide excision mandibulectomy and mandibular reconstruction with an ALT flap and a titanium implant were performed. The prefabricated titanium implant was fixed to the condyle. Then, an ALT flap was harvested from the ipsilateral thigh and anastomosed. After confirming that the circulation of the flap was intact, the implant was fixed to the parasymphysis. On the radiograph taken after the surgery, the prosthesis was well positioned and overall facial shape was acceptable. There was no postoperative complication during the follow-up period, 1 year and 2 months. The prefabricated implant allows the restoration of facial symmetry without harvesting autologous bone and it is a safe and effective surgical option for mandibular reconstruction.
