족관절 고정술은 족관절에 발생한 심한 관절염(end-stage arthritis)에서 전통적으로 시행하던 술식으로 현재 사용되고 있는 인공 족관절 치환술이 발달되기 전까지는 gold standard 로 알려져 있었으며 현재에도 심한 족관절의 변형이나 파괴, 족관절 인공 관절의 실패시에 시행되고 있다. 1897년 Albert가 처음으로 족관절 고정술을 소개한 이후로 30여가지가 넘는 방법이 행해지고 있으나 개방적 관절 고정술의 단점인 수술 후 염증, 유합 지연, 연부조직의 손상에 의한 피부 괴사 등을 극복하고 유합물을 높이기 위해 다양한 내고정 및 외고정 장치를 사용하고 있다. 관절경 술식이 발달하면서 Schnider가 1983년 최초로 관절경을 이용한 족관절 고정술을 발표한 이후로 관절경하의 족관절 고정술은 개방적 족관절 고정술 보다 높은 유합율과 적은 수술 합병증으로 인해 관심의 대상이 되었지만 족관절의 변형이 심한 경우에는 시행하기 어려운 단점이 있는 것으로 알려져 왔다.

관절와 및 상완골의 의미 있는 골결손을 동반한 불안정한 견관절에 대해 어떻게 최선의 치료를 할 것인가에 대한 의문은 남아있다. 어떤 저자들은 외회전과 외전을 제한하는 것으로 Hill-Sachs 병변의 진입을 예방하는 일종의 관혈적 관절낭 변위를 통한 제한된 상완와관절 운동을 주장해왔으며, 다른 관혈적 시술들은 극하근건과 관절낭을 Hill-Sachs 병변 내로 관혈적 전이시키는 것으로 기술되어왔다. 최근에는 여러 저자들에 의해 Hill-Sachs 병변의 진입을 치료하는 더 새로운 접근법들이 기술되었으며, Bankart 병변 복원술에 더하여 Hill-Sachs 병변을 채우기 위해 관절경 하 후방 관절낭 고정술과 극하근건 고정술로 이루어진 이른바 'Remplissage'술기가 소개된 바 있어, 이에 저자는 외상성 견관절 불안정성으로 관절경 하 Bankart 병변 복원술 및 관절낭 축화술 시행 후 외상으로 재발된 견관절 불안정성이 발생하여 관절경 하 Bankart 병변 복원술과 함께'Remplissage'술기를 이용한 Hill-Sachs 병변 복원술을 시행한 예를 보고하는 바이다.

Purpose : This study was conducted to analyze the results of arthroscopic ankle arthrodesis and to verify the advantages of the technique compared to open ankle arthrodesis. Materials and Methods : Between October 1992 and August 1996, the arthroscopic ankle arthrodesis had been performed in five patients(six ankle joints): two patients with seropositive rheumatoid arthritis(one patient surgically treated bilaterally), two with osteoarthritis and one with tuberculous arthritis. There were one man and 4 women. Average age was 48 years ranging from 38 to 65 years. Follow up period was average 45 months(range, $12\~80$). Results : All patients were successfully treated with ankle joint arthrodesis under arthroscopic control. The mean time to fusion was 10 weeks(range, $6\~15$). There was a $100\%$ fusion rate without any complication. Conclusion : The arthroscopic ankle arthrodesis was successful in all cases with less morbidity and short hospital stay. It was technically feasible with excellent predictability.

Purpose: This study compared the functional and radiologic outcomes of intramedullary nailing (IMN) and minimally invasive plate osteosynthesis (MIPO) for tibia fractures in distal tibial spiral fractures combined with posterior malleolar fractures, as well as the functional and radiologic outcomes with and without fixation for posterior malleolar fractures. Materials and Methods: From January 2010 to December 2018 the radiological and clinical outcomes of 30 skeletally mature patients with tibial spiral fractures (AO Foundation/Orthopaedic Trauma Association classification 42-A1, B1, C1) combined with posterior malleolar fractures were analyzed. Sixteen patients were treated with IMN, and 14 patients were treated with MIPO. Depending on the surgical methods, the radiologic and clinical outcomes were compared by evaluating the bone union time, postoperative alignment, postoperative displacement of the posterior malleolar fragment, and American Orthopaedic Foot and Ankle Society (AOFAS) score. Moreover, the functional and clinical outcomes with and without fixation for posterior malleolar fractures were compared. Results: The mean bone union time was 21.8 weeks in the IMN group and 23.1 weeks in the MIPO group (p=0.500). At the final follow up, the mean alignment was coronal angulation of 1.8°, sagittal angulation of 1.6° in the IMN group and coronal angulation of 1.2° and sagittal angulation of 1.7° in the MIPO group (conoral angulation: p=0.131, sagittal angulation: p=0.850). The postoperative and final radiologic evaluation showed no displacement of the posterior malleolar fragment and excellent joint congruity in all cases. At the final follow-up, the mean AOFAS score was 88.0 on average in the IMN group and 87.6 on average in the MIPO group (p=0.905). The ankle range of motion and AOFAS score were similar in the fixation group and no fixation group for posterior malleolar fractures. Conclusion: Both IMN and MIPO for tibial spiral fractures combined with posterior malleolar fractures result in satisfactory radiological and clinical outcomes.

Arthrodesis is one of the last options available to obtain a stable, painless knee in patients who are unable to undergo reconstructive surgery due to a damaged knee joint. A variety of techniques have been used, including external fixation, internal fixation by compression plates, intramedullary fixation through the knee with a modular nail, and antegrade nailing through the piriformis fossa. Another option is the use of a short nail such as the Neff nail, the Wichita nail, or the Huckstep nail, but there are no commercial short nails available for use in Korea. This technical report describes a technique for knee arthrodesis using a retrograde femoral intramedullary nail.

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 reviewed the results of ankle arthritis with advanced deformity treated with open arthrodesis. Materials and Methods: Seventeen patients who had painful ankle arthritis with advanced deformity underwent open arthrodesis using chevron osteotomy or transfibular approach and were followed for an average of 4.2 years (range, 1.5 to 9.7 years). The average age was 51.4 years and the most common cause was traumatic arthritis (13 patients). Postoperative outcome was evaluated using Mazur's grading system for ankle function. we also checked time to union, patient satisfaction, complications, position of arthrodesis and degenerative changes of adjacent joints. Results: Clinical score was improved to 76.4 points from 46.7 points. Average time to union was 4.3 months and the rate of satisfaction was 88%. Complications included 1 nonunion, 2 malunion, 1 superficial infection and 1 combined delayed union and malunion. There were 14 cases within $5^{\circ}$ valgus in frontal plane and 13 cases within neutral to $5^{\circ}$ dorsiflexion in sagittal plane. 3 cases in chevron osteotomy revealed valgus and plantarflexed position over $5^{\circ}$. Degenerative changes of adjacent joints was seen in 2 patients. Conclusion: Open arthrodesis for ankle arthritis with advanced deformity shows favorable clinical outcome. Transfibular approach shows more consistent results than chevron soteotomy for desired position of arthrodesis.
