During bone tumor resection, many cases require medial malleolar osteotomy to achieve adequate access to the operative field. Various osteotomy methods have been developed to address this issue, including oblique, transverse, reverse V-shape, and step-cut osteotomies. However, medial malleolar osteotomy has several drawbacks, such as the excessive disruption of the joint surface, unstable screw fixation when fixing the medial malleolus, and iatrogenic medial ankle joint arthritis due to articular displacement during the reduction of the osteotomy site. In addition, there is a possibility of injury to the posterior tibial artery, tibial nerve, or posterior tibialis tendon if the osteotomy range is too aggressive. Therefore, the authors propose a new osteotomy method, which has shown promising clinical results, namely, partial posterior medial malleolar osteotomy. This method minimizes articular involvement and provides adequate access to the operative field during talar body bone tumor resection.

For the adequate intraarticular exposure in medial talar dome lesions, medial malleolar osteotomy is necessary in some cases. Many operative techniques including transverse, oblique, inverted V-shape, crescentic and step-cut osteotomies of the medial malleolus have been described previously. But their techniques have several problems such as nonunion, rotation and limited access to lesions. So we introduce the new reverse chevron medial malleolar osteotomy which provides excellent access to lesions, good stability and a broad cancellous surface for rapid healing.

Purpose: Osteochondral lesion of the talus (OLT) has traditionally been treated using an autologous osteochondral graft via the medial malleolar approach. Here, we compare the traditional method with the anterior arthrotomy approach. Materials and Methods: Between January 2005 and June 2015, 24 cases of patients who received autologus osteochondral graft for OLT and with at least 2 years of follow-up were evaluated. They were divided into two groups; one group receiving autologous osteochondral graft via the medial malleolar osteotomy approach (group 1, n=9) and another group via the anterior arthrotomy approach (group 2, n=15). The clinical outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) score. Results: In all cases, the size of the subchondral cyst of the talus decreased, if not disappeared on the final follow-up radiograph. All osteochondral grafts were united. The mean AOFAS score increased from 61.5 preoperatively to 84.9 at the final follow-up. The mean AOFAS score of group 1 increased from 60.3 preoperatively to 78.0 (p=0.007) at the final follow-up, and the mean AOFAS score of group 2 also increased from 62.2 to 89.1 (p=0.006). The AOFAS score was statistically better in group 2 than in group 1 (p=0.034) at the final follow-up. Conclusion: Autologous osteochondral graft of the OLT yields satisfactory radiologic and clinical outcomes. Especially, better clinical outcome was observed in the group using the anterior arthrotomy approach (group 2) than in the group using the medial malleolar osteotomy approach (group 1).

Purpose: The purpose of this study is to assess the results of the autologous osteochondral grafting harvested from medial side of talus for relatively large osteochondral lesion of the medial talar dome. Materials and Methods: From October 2004 to September 2005, 12 patients with osteochondral lesion measured more than 10 mm in axial MRI who were followed up more than 1 year after operation were analyzed. We evaluated postoperative symptoms by Mann and Reynolds scale, morbidity of donor site, and compared the range of both ankle motion. We also evaluated the union at the medial malleolar osteotomy site, trabecular connection between the grafted osteochondral mass and talus, irregularity of the articular surface in lesion. Results: Clinical results were rated as excellent in 4, good in 7, fair in 1. The mean angle of the total range of motion in affected ankle was decreased by 3 degrees compared to that in unaffected ankle. We did not observe abnormal findings at donor site. The osteotomized bone was united at mean 9 weeks (range, 8-12 weeks). We observed trabecular connection between grafted osteochondral mass and talus at mean 14 weeks (range, 12-16 weeks). We also observed irregular articular surface in osteochondral lesions in 6, smooth articular surface in 6. Conclusion: The local autologous osteochondral graft for relatively large osteochondral lesion of the medial talar dome is useful operative method with advantages of wide operative field, low morbidity of donor site, and high satisfaction rate.

목적: 족관절 내과 절골술 및 대형신연기를 이용하여 전내측 접근법으로 수술적 처치를 시행한 제3형 거골 경부 골절 환자들의 임상적, 방사선적 결과를 후향적으로 분석하여 보고하고자 하였다. 대상 및 방법: 2009년 3월부터 2016년 8월까지 조선대학교병원에서 족관절 내과 절골술 및 대형신연기를 이용하여 전내측 접근법으로 수술적 처치를 시행한 제3형 거골 경부 골절 환자 중 12개월 이상 추시가 가능했던 12명(12예)을 대상으로 하였다. 술 후 6주에 외래 추시 시 시행한 전후면 및 측면 단순 방사선 사진으로 Hawkins sign의 유무를 확인하였고 술 후 3개월에 자기공명영상 촬영을 시행하여 무혈성 괴사 여부를 판정하였다. 이후 3개월 간격으로 단순 방사선 사진 및 임상 증세 기반으로 골유합 여부 및 시기를 판정하였고 술 후 12개월에 시행한 단순 방사선 사진으로 후외상성 관절염 발생 여부 및 Takakura stage를 판정하였으며 미국족부족관 절정형외과학회(American Orthopaedic Foot and Ankle Society, AOFAS)의 족관절-후족부 수치(ankle-hindfoot score)를 조사하여 분석하였다. 결과: 7예에서 술 후 3개월에 시행한 자기공명영상상 무혈성 괴사가 발생하였으나 모두 술 후 12개월 추시에서 수술적 처치 없이 AOFAS 점수 83.86±4.53점이라는 결과를 얻었다. 전 예에서 평균 5.3개월에 방사선적 골유합을 얻었고 총 10예에서 방사선적 후외상성 관절염이 발생하였으나 모두 Takakura stage IIIA 이하로 보존적 처치를 통하여 일상생활이 가능하였다. AOFAS 족관절-후족부 수치는 평균 85.17점으로 측정되었다. 그 외 합병증으로 2예에서 얕은 창상 감염이 발생하였다. 결론: 제3형 거골 경부 골절 환자의 수술적 치료에 있어 족관절 내과 절골술 및 대형신연기를 이용한 전내측 접근법은 외측 절개 없이 해부학적 전위 골편의 정복을 얻을 수 있어 거골의 혈류를 비교적 보존할 수 있는 수술적 접근법 중 하나가 될 수 있을 것으로 판단된다.

Purpose: The purpose of this study is to compare the two prosthesis that used for total ankle arthroplasty. Materials and Methods: From Sept. 2003 to Jun 2006, 13 patients and 14 ankles that could be follow up more than 1 months. Semiconstrained type (Group I, 7 cases) and Unconstrained type (Group II, 7 cases) were used for total ankle arthroplasty. Mean age was 63.2 year-old, 12 ankles are men and 2 ankles were women. Mean follow up periods were 29 months. The criteria to compare the clinical result were postoperative range of motion, AOFAS score and residual bone stock of medial malleolus. Results: Postoperative range of motion of group I was $43.6{\pm}9.4$ degrees and of group II was $50.7{\pm}7.3$ degrees (p=0.115). Postoperative AOFAS score of group I was $77.1{\pm}13.0$ points and of group II was $86.0{\pm}5.7$ points (p=0.094). Resected bone stock in medial malleolus of group I was $10.7{\pm}2.5\;mm$ and of group II was $5.1{\pm}1.2\;mm$ (p=0.003). Total number of complication in our study was 9 cases. 3 cases were a malleolar fracture, two occurred at intra-operation, the other at follow-up period. Re-operation was done in 6 cases, 3 cases were calcaneal corrective osteotomy, 2 cases were resection of a heterotopic bone and one case was pedicular flap operation for skin problem. Conclusion: In our hospital, mobile bearing type prosthesis shows good result than a semiconstrained type in respect of residual bone stock in medial malleolus. Postoperative range of motion and AOFAS score between two groups shows no significant difference. But small number of patients and short term follow up period is a defect in our study, afterward more population and long term follow up period are needed.
