목적: 본 연구는 족관절 후과 골절을 동반한 경골 원위부 나선상 골절에서 경골에 대한 고정술로 골수강 내 금속정 고정술과 최소 침습적 금속판 고정술의 기능적, 방사선학적 결과 및 후과 골절에 대한 고정술 유무에 따른 기능적, 방사선학적 결과를 비교하였다. 대상 및 방법: 2010년 1월부터 2018년 12월까지 본원에서 족관절 후과 골절을 동반한 경골 원위부 나선상 골절(AO Foundation/Orthopaedic Trauma Association 분류 42-A1, B1, C1) 30명의 환자를 대상으로 연구하였다. 골수강 내 금속정 고정술을 시행한 16명을 intramedullary nailing (IMN)군으로, 최소 침습적 금속판 고정술을 시행한 14명을 minimally invasive plate osteosynthesis (MIPO)군으로 분류하여 양 군의 골유합 시기, 술 후 각 정렬, 족관절 후과 골편의 전위 정도 및 American Orthopaedic Foot and Ankle Society (AOFAS) 점수를 비교, 분석하였다. 또한 각 군에서 후과 골절에 대한 고정술 유무에 따른 족관절 관절 운동 범위 및 AOFAS 점수를 비교하였다. 결과: 평균 골유합 시기는 IMN군에서 21.8주, MIPO군에서 23.1주였다(p=0.500). 최종 추시 평균 각 변형은 IMN군에서 관상면 1.8°, 시상면 1.6°를 보였고, MIPO군에서 관상면 1.2°, 시상면 1.7°를 보였다(p=0.131, p=0.850). 술 후 및 최종 추시 방사선 사진상 양 군 모든 환자에서 족관절 후과 골편의 전위는 없었고, 최종 추시에서 족관절 관절염은 없었다. 임상적 평가로 최종 추시에서 AOFAS 점수는 IMN군에서 평균 88.0점, MIPO 군에서 평균 87.6점을 보였다(p=0.905). 각 군에서 후과 골절에 대한 고정술 유무에 따른 족관절 관절 운동 범위 및 AOFAS 점수를 비교하였고 유의한 차이는 없었다. 결론: 족관절 후과 골절을 동반한 경골 원위부 나선상 골절의 치료에서 골수강 내 금속정 고정술과 최소 침습적 금속판 고정술은 영상학적, 임상적 결과에서 차이가 없이 모두 우수한 결과를 보였다.

Irreducible fracture dislocation of the ankle associated with comminuted displaced fracture of posterior malleolus is rare. Locked posterior malleolar fragments interfere with reduction of fibula or talus in ankle fractures. Prompt recognition and appropriate surgical approaches are necessary to achieve anatomical reduction of the ankle fractures.

The posterior malleolar fracture is relatively common fracture of the foot and ankle, but several aspects of this are still controversial. If the posterior malleolus is involved in the ankle fracture, the prognosis is usually poor. A computed tomography scan is essential for accurate diagnosis and treatment planning. Although indirect reduction and the anterior to posterior screw fixation technique have the advantages of a small incision with the requirement of relatively simple skills, direct open reduction and fixation from the posterior side provide a more biomechanically stable and accurate reduction. The precise reduction of the posterior malleolar fragment helps to achieve congruency of the tibia and fibula in the incisura and contributes to syndesmotic stability. It is important to determine the indications for surgical treatment by comprehensively evaluating the three-dimensional structure of the posterior malleolar fracture and all related injuries to the ankle.

Purpose: The purpose of this study is to compare the radiologic and clinical results of syndesmotic screw fixation and posterior malleolar fixation for syndesmotic injury in Lauge-Hansen classification pronation-external rotation (PER) stage IV ankle fractures with posterior malleolus fracture. Materials and Methods: We designed a retrospective study that included patients with Lauge-Hansen classification PER stage IV ankle fracture with posterior malleolus fracture. Of 723 patients who underwent ankle fracture surgery from March 2005 to November 2012, 29 were included in this study. In this study, syndesmotic injury was treated with syndesmotic screw fixation or posterior malleolus fixation. There were 15 cases of syndesmotic screw fixation and 14 cases of posterior malleolar fixation. We compared the radiologic and clinical results at one year postoperatively. Posterior malleolus fragment size on a pre-operative computed tomographic image, and tibiofibular overlap, medial clear space, articular step-off, Kellgren-Lawrence grade, and Takakura classification on a postoperative one year followup radiograph were used for comparison of the radiologic results. The clinical results were assessed using the American Orthopaedic Foot and Ankle Society score, visual analogue scale score, and patient subjective satisfaction score. Results: Posterior malleolar fragment size was $12.62%{\pm}3.01%$ of the joint space in the syndesmotic screw fixation group and $27.04%{\pm}4.34%$ in the posterior malleolar fixation group. A statistical difference was observed between the two groups. However, other results, including tibiofibular overlap, medial clear space, articular step-off, Kellgren-Lawrence grade, Takakura classification, and clinical scores showed no statistical difference. Conclusion: In the Lauge-Hansen classification PER stage IV ankle fracture with posterior malleolus fracture, if the posterior malleolus fracture can be reduced anatomically and fixated rigidly, syndesmotic screw fixation, which can cause several complications, is usually not required for achievement of a satisfactory syndesmotic stability; this would be a recommendable option for treatment of syndesmotic injury.

Purpose: The purpose of this study was to assess the 2-year follow-up results of patients with a trimalleolar fracture, who had undergone an anterior incision cannulated screw fixation of the posterior malleolar fragment, which had more than 25% of articular involvement or had no cortical continuity with the distal tibia. Materials and Methods: Among 28 patients with a trimalleolar fracture who had undergone fixation of the posterior malleolar fragment between February 2005 and February 2010, 14 patients, who underwent an anterior incision cannulated screw fixation of posterior malleolar fragment and were followed-up for more than 2 years, were selected. The postoperative clinical and radiological findings immediately and at the 1- and 2-year follow-up were compared. The clinical findings were evaluated as American Orthopaedic Foot and Ankle Society (AOFAS) score. The radiological assessment was evaluated as the maintenance of reduction, period to bone union, and the presence of nonunion, malunion, and complications. Results: The clinical outcome by mean AOFAS score revealed 83.0 points in the group with preoperative displacement below 2 mm and 80.7 points in the group with preoperative displacement above 2 mm postoperatively. The mean AOFAS score was 91.7 and 93.1 points in the group with preoperative displacement below 2 mm on 1- and 2-year follow-up, respectively, and 89.8 and 91.7 points in group with the preoperative displacement above 2 mm on 1- and 2-year follow-up, respectively. After a 2-year follow-up among 14 cases selected for this study, 13 cases showed an excellent reduction state and only 1 case (7.1%) showed a displacement of more than 2 mm. No complication were encountered in the group with preoperative displacement below 2 mm. On the other hand, among 8 patients in the group with preoperative displacement above 2 mm, there were 3 with limitations of the range of motion of the ankle joint (37.5%) and 1 post-traumatic arthritis (12.5%) at the 2-year follow-up. Conclusion: Anterior incision cannulated screw fixation of the posterior malleolar fragment could be a valuable method for the treatment of trimalleolar fractures that provides satisfactory results.
