Purpose: The purpose of this study was to evaluate the radiographic results and complications after the proximal dome osteotomy for hallux valgus. Material and Methods: 127 cases of clinically moderate to severe hallux valgus from October 1994 to September 1997 were included in this study. All had been surgically corrected with proximal dome osteotomy, bunionectomy, and distal soft tissue release. We compared the hallux valgus angle(HVA) and intermetatarsal angle(IMA) at preoperative, postoperative 3 weeks, postoperative 6 weeks, and postoperative 3 months. Also we reviewed the postoperative com plications. Result: The HVA averaged $34.1^{\circ}$ at preoperative, $4.3^{\circ}$ at 3 weeks after operation, $8.1^{\circ}$ at 6 weeks after operation, and $10.2^{\circ}$ at 3 months after operation. The lMA averaged $14.6^{\circ}$ at preoperative, $5.1^{\circ}$ at 3 weeks after operation, $5.6^{\circ}$ at 6 weeks after operation, and $7.3^{\circ}$ at 3 months after operation. We experienced 7 cases of malunion, 5 cases of limitation of motin at the first metatarso-phalangeal joint, 3 cases of hallux varus deformity, 2 cases of delayed union. Conclusion: Proximal dome osteotomy for moderate to severe hallux valgus deformity was considered as one of the effective treatment methods. And we try to avoid limitation of motion at the first metatarso-phalangeal joint after operation.

Purpose: To evaluate the effectiveness of ankle arthrography in diagnosis and treatment of the ankle sprain. Materials and Methods: Arthrography was performed to eighteen patients who were diagnosed as ankle sprain clinically from September, 1990 to April, 2003. Splint immobilization for three days and return to daily life were for the eleven patients who showed normal limits of extension of joint and no dye leakage on arthrography, cast for 3 weeks and compression brace wearing were for 4 patients who showed anterior talofibular ligament tear on arthrography. 3 patients diagnosed as anterior talofibular and calcaneofibular ligament tears were treated with cast for 6 weeks and then brace for 3 weeks. Results: The range of motion of the injured joint was recovered normally at the time of 3 month of postoperative follow up examination. But two patients complained a mild pain after exercise but it did not affect ordinary activities. Eleven patients who were normal on arthrography returned to daily activities in a week. Conclusion: It is reasonable to determine the extent of ankle sprain and treatment method for it using arthrography.

Purpose: The diabetic foot lesions are intractable, and aggravation often leads to amputation. None or minor amputation group was treated debridement or toe amputation and major amputation group was treated Ray, Lisfranc, Chopart, Below Knee and Above Knee amputation. We investigate the risk factors for major limb amputations among patients with diabetic foot lesion. Materials and Methods: The subjects were 73 diabetic foot lesion patients (83 diabetic foot lesions) treated at our department from January 2006 to December 2010. Non or Minor amputation group of 44 cases were treated with debridement or toe amputation. Major amputation group of 39 cases were treated with Ray, Lisfranc, Chopart, below or above Knee amputation. We investigated socioeconomic factors, diabetes mellitus related factors and wound related factors and laboratory factors. Statistical analysis was done by Students t-test, Chi-square test, Mann-Whitney's U test. Results: In our analysis, wound size, wound classification (Wagner classification, Brodsky classification), white blood cell counts, polymorphoneuclear neutrophil percentage, hemoglobin, C-reactive protein and albumin were risk factors for major amputation (p<0.05). Conclusion: Low education level, nutritional condition, premorbid activity level and progressed wound condition were observed in major amputation group compared with non or minor amputation group. In the major amputation group, higher white blood cell count, C-reactive protein level and lower albumin level were observed. Together with maintenance of adequate nutritional condition, early detection of lesions and foot care for early treatment is important. Therefore, active investigation with full risk evaluation of vascular complication is also important.

Between 1992 and 1996, 5 patients with the giant-cell tumor of the spine were treated. Four were female and one was male. The mean age was 34 years old, and the mean follow-up time was 36 months. The locations of the lesions were the cervical spine in 1, the thoracic spine in 3, and the lumbar spine in 1. Pain was the predominant presenting symptom in all cases and four had a neurological deficit. A combined anterior and posterior surgical approach wds as performed in all cases, which were also treated with AIF(anterior interbody fusion) and anterior and/or posterior instrumentation. Adjuvant radiation therapy was performed in 1 case of cervical spine. At the final follow-up, the pain and neurologic symptoms were improved. Radiologic examination showed no evidence of local recurrence and no failure of instrumentation of the spine.

Squamous cell carcinoma is a neglected disease entity in orthopedic oncology. The purpose of this study was to analyze overall survival and the role of surgery on survival and to evaluate the significance of possible prognostic factors. From Oct, 1986 to Aug, 1996, 57 patients were enlisted and 42 patients ere eligible. Inclusion criteria included more than one year follow-up and no distant metastasis at the first visit. Staging and survival followed AJC classification and Kaplan-Meier plot. Stage II included 17 cases and stage III, 25 cases. Thirty-eight patients underwent operations, chemotherapy, and/or radiotherapy, and the remaining four had operations only. The chemotherapeutic regimen was adriamycin-cisplatin. The average follow-up period was 45 months. The ten-year actuarial survival rate of whole patients was 65.4%. Location of primary lesion, stage, pathologic grading, and intensity of chemotherapy in the same stage showed a significant difference in survival. Nine out of 42 patients had local recurrence. Seven patients had inadequate wide margins and two had intralesional margins. Average period of recurrence from operation was 13(4-35)months. The operation itself had no impact on survival but a surgical margin of no less than 3cm from the lesion was important for local control. Pathological grade and staging were significant variables for long term survival. Acral lesion had a significantly higher chance of regional and distant metastasis but actual survival showed no difference. In stage II, aggressive chemotherapy could delay or reduce the chance of regional or distant metastasis.

Osteosarcoma is the most common primary bone tumor except for multiple myeloma. Hematogenous spread of osteosarcoma presents the t1susal route of dissemination. Lung metastasis is the most common, however the lymph node involvement is quite rare. In addition, according to Mirra, radiologically detectable involvement of lymph node is an extremely rare manifestation of osteosarcoma. The authors had experienced a patient with an osteosarcoma of the right distal femur which spread to the right inguinal lymph node and lung. After preoperative chemotheraphy, a limb salvage operation was performed around the lesion of right distal femur and the right inguinal lymph nodes were dissected. A adjuvant postoperative chemotheraphy was performed. After the treatment, there was no recurrence of osteosarcoma or any other metastatic evidence for two years and 8 months.

Purpose: We present our experience about the clinical aspect and treatment modalities of ostechondritis dissecans of the talus. Material and Method: This study included 35 patients, 38 cases diagnosed as ostechondritis dissecans of the talus that were proved by clinical and radiologic finding. The methods of treatment were conservative (2 cases), multiple drilling (1 case), excision (1 case), excision, curettage & multiple drilling (23 cases), curettage & bone peg fixation (2 cases), curettage & bone graft (2 cases), and autogenous osteochondral transfer(Mosaicplasty) (7 cases). Results: Of the 38 cases, 30 cases were associated with a history of trauma (17 cases of medial lesion, 13 cases of lateral lesion), and 9 cases of which had major trauma history and 21 cases, minor repetitive trauma history. According to O'Farrel grading system, 21 cases (55%) had good results, 11 cases (29%) had fair results, and 6 cases (16%) had poor results. Of the medial lesion 16 cases had good results, 6 cases, fair results, and 2 cases, poor results. Of the lateral lesion 5 cases had good results, 5 cases, fair results, and 4 cases, poor results. Conclusion: There were fair or good results in 84% of patients with surgical treatment. Curettage and multiple drilling reveals a good result in medial lesion in grade I, II, III and lateral lesion in grade I, II. Autogenous osteochondral transfer(Mosaicplasty) is considered for the cases in grade III, IV(medial and lateral), lesion exceeds 1Cm of size and poor result with another treatment modality.

Purpose: To evaluate the clinical and functional results of ankle arthroplasty and to analyze the complications in total ankle arthroplasty. Materials and Methods: Between October 1988 and October 1991, the total ankle arthroplasty had been performed in eight ankle joints of seven patients.. There were five patients with rheumatoid arthritis, one with osteoarthritis and one with traumatic arthritis. One patient had bilateral replacement. New Jersey type of prosthesis was used in six patients and one patient was performed with Odland type of prosthesis. The average age at surgery was 42.3 years (range, 33-54 years). The average follow-up period was 8.2 years (range, 6-10.5 years). Clinical evaluation was assessed according to the Ankle-Hind Foot Scale of American Orthopedic Foot and Ankle Society. Results: The average score was 81.4 (range, 76 - 90) at the most recent follow-up. All patients were satisfied with their clinical results. Relief of pain was excellent in most patients, but postoperatively there was no significant improvement in range of motion. One patient had arthrodesis at three year six months after total ankle arthroplasty due to deep infection. Conclusion: This study shows total ankle arthroplasty is a good alternative treatment in selected cases of osteoarthritis and rheumatoid arthritis.

Purpose: Recurrence is one of the most common complications after primary correction for hallux valgus deformities. The purpose of this study was to evaluate the usefulness of Scarf osteotomy with axial decompression in the treatment of recurrent hallux valgus. Materials and Methods: From April 2006 to April 2011, 14 cases (12 patients) of recurrent hallux valgus were managed with shortening Scarf osteotomy. Preoperative and postoperative radiographs were reviewed for the measurement of the hallux valgus angle (HVA), intermetatarsal angle (IMA), and the amount of the $1^{st}$ metatarsal shortening. Clinical outcomes including the visual analogue scale (VAS), the AOFAS score, and the range of motion [ROM] of the 1st metatarsophalangeal (MTP) joint were evaluated. Results: The mean HVA decreased from 27.9 degrees to 5.2 and the mean IMA decreased from 12.9 to 3.4. The mean VAS improved from 5.3 to 0.3 and the mean AOFAS score improved from 41 to 90. The mean amount of the 1st metatarsal shortening was 3.4 mm (2-5). The mean ROM of the $1^{st}$ MTP joint improved from 22 degrees (15-35) to 68 (55-75). Conclusion: Scarf osteotomy associated with axial decompression can be a useful revision procedure for the treatment of recurrent hallux valgus deformity.
