Ossifying fibroma is one of a group of fibro-osseous lesions which arises typically within the jaw bones and only rarely affects the long bones. Ossifying fibroma of the long bones almost involve exclusively the tibia but may also involve the fibula. Ossifying fibroma of the long bones is distinct from fibrous dysplasia, adamantinoma and nonossifying fibroma with regard to age of the patient, site, radiographic appearance, histological features, and clinical course. We are reporting the cases of seven patients with a tumor-like lesion that named osteofibrous dysplasia. It is most commonly found in the tibia and fibula of a child ten years of age or younger. Of the seven cases reported in this study, only one patient was younger than ten years. In all cases, the lesions were usually located in the tibial diaphysis. The average duration of clinical manifestation was 5.2 years. The clinical symptoms were anterior bowing of the tibia in 2 cases, buldging of the tibia in 2 cases, and mass overlying the tibia in 3 cases. On the roentgenography, it shows multiple radiolucent lesion with intervening sclerotic rim of the tibial diaphysis. In seven patients, 6 cases were confirmed with biopsy. We had done curettage and bone graft in three cases, VFG was done in one case. The other three cases underwent conservative management.

김경태(Kyung Tae Kim),이송(Song Lee),배은환(Eun Hwan Bae),김현수(Hyun Soo Kim),박준성(Joon Seong Park),차상규(Sang Gyu Cha) 대한정형외과학회 2005 대한정형외과학회지 Vol.40 No.2

목적: 인공슬관절 부분치환술을 시행한 환자들의 전향적인 추시 관찰을 통해 수술 후 시간 경과에 따른 변화를 비교하고 최종 추시 결과를 분석함으로써 인공슬관절 부분치환술의 초기 결과를 알아보고자 하였다. 대상 및 방법: 2002년 1월부터 본원 정형외과에서 시행한 인공슬관절 부분치환술 중 수술 후 2년이 경과하고 수술 후 3개월, 6개월, 12개월 및 24개월에 정기적 추시가 가능했던 67예를 대상으로 전향적 조사 방법을 사용하여 임상적 평가와 함께 방사선학적 변화 등을 확인하여 기간 경과에 따른 변화를 비교하고 최종 추시 결과를 분석하였다. 결과: 수술 후 2년까지 정기적 추시가 가능했던 67예에서 슬관절 점수는 수술 전 평균 54.6점에서 수술 후 3개월 80.1, 6개월 85.4, 12개월 86.8, 24개월 89.2점으로 증가되었고 기능 점수는 수술 전 평균 56.3점에서 수술 후 3개월 70.4, 6개월 76.0, 12개월 80.2, 24개월 83.0점으로 증가되었다. 슬관절 운동 범위는 수술 전 127.6˚에서 수술 후 3개월에 128.6˚로 회복되었고 대퇴경골각은 수술 전 0.7° 외반에서 수술 후 24개월에 5.7° 외반으로 변화했다. 결론: 슬관절의 퇴행성 관절염에 시행한 인공슬관절 부분치환술에서 만족할만한 슬관절 점수와 기능 점수의 향상 및 관절 운동의 회복을 수술 후 조기에 얻을 수 있었고 단기 추시 결과도 비교적 우수한 결과를 보였다. Purpose: To evaluate the early postoperative results of Unicompartmental Knee Arthroplasty (UKA) based on a prospective analysis and follow up study. Materials and Methods: Clinical assessments were carried out using the Knee Society Score (KSS) rating system. The tibiofemoral angle and radiographic changes were measured using weight-bearing X-rays. Prospective assessments were conducted preoperatively, and regularly followed up after the operation. Among the cases of UKA performed since January 2002, 67 were able to be followed up at 3, 6,12 and 24 months after the operation. Results: For these 67 knees, the average preoperative knee score and the knee function score were 54.6 and 56.3 points, respectively. The knee score was improved to 80.1, 85.4, 86.8 and 89.2 points at 3, 6,12 and 24 months follow ups, respectively. The knee function score was also improved to 70.4, 76.0, 80.2 and 83.0 points at 3,6,12 and 24 months. The average range of knee motion was 127.6 degrees preoperatively, and recovered to 128.6 degrees at 3 months postoperatively. The preoperative tibiofemoral angle was 0.7 degrees of valgus, which changed to 5.7 degrees of valgus at 24 months postoperatively. Conclusion: As shown in this prospective study, the early postoperative results of UKA were satisfactory for improvement of knee score, function score and in the recovery of knee motion.

김경태(Kyung Tae Kim),이송(Song Lee),배은환(Eun Hwan Bae),최대정(Dae Jung Choi),박훈석(Hoon Seok Park),조근호(Kun Ho Cha) 대한정형외과학회 2006 대한정형외과학회지 Vol.41 No.1

목적: 슬관절의 내측 구획에 시행한 슬관절 부분치환술 후 대퇴경골간 정렬의 변화를 알아보고 이에 영향을 미치는 인자들을 규명하고자 하였다. 대상 및 방법: 2003년 1월부터 2003년 12월까지 슬관절의 내측 구획에 발생한 퇴행성 관절염으로 최소침습 슬관절 부분치환술을 시행 받은 114명, 128슬관절을 대상으로 하였다. 수술 전 및 수술 후 3개월에 체중부하 방사선 사진을 촬영하여 대퇴경골각, 경골 및 경골 삽입물의 후방 경사각, 대퇴 및 경골 삽입물의 각변형 동을 각각 측정하였다. 방사선학적 측정값과 삽입물의 종류, 삽입물의 가동성 유무 및 두께, 술자, 환자의 연령 등 여러 인자들의 교정된 대퇴경골각에 대한 영향 여부를 통계학적 방법을 이용하여 알아보았다. 결과: 대상 전체의 술전 평균 대퇴경골각은 내반 0.6도에서 술후 외반 5.2도로 평균 5.8도 교정이 되었다. 가동형 삽입물을 사용한 군의 평균 교정각은 6.1도로 고정형 삽입물을 사용한 군의 평균 교정각 3.6도에 비하여 의미있게 컸다(p<0.0001). 술전 대퇴경골의 내반 변형이 심할수록 대퇴경골각의 교정이 많이 이루어졌으나(p<0.0001) 폴리에틸렌 삽입물의 두께에 따른 의미 있는 변화는 보이지 않았다. 대퇴 및 경골 삽입물의 각변형이나 후방 경사각 등은 대퇴경골각의 교정에 영향을 주지 않았으며 술자 및 연령에 따른 차이도 없었다. 결론: 최소 침습 슬관절 부분치환술 후 대퇴경골각은 평균 5.8도 교정이 되었으며, 수술 후 대퇴경골간 정렬은 수술 전 대퇴경골간 변형의 정도와 삽입물의 종류에 따라 영향을 받았다. Purpose: We analyzed affecting factors associated with the tibiofemoral alignment after minimally invasive unicompartmental knee arthroplasty (UKA) used to treat medial compartmental osteoarthritis of the knee. Materials and Methods: From January 2003 to December 2003, 128 UKA were performed in 114 patients with minimally invasive surgery. The revealed tibiofemoral angle, tibial translation, posterior slope and the coronary orientation of the tibial and femoral component were measured using the preoperative and postoperative weight-bearing radiographs. The possible factors associated with the corrective tibiofemoral angle were analyzed statistically. Results: The average corrective angle of the tibiofemoral axis was 5.8˚ from varus 0.6˚ preoperatively to valgus 5.2˚ postoperatively. The average corrective angle of the tibiofemoral axis was 6.1˚ in the mobile bearing group and 3.6˚ in the fixed bearing group. There was significantly more corrective tibiofemoral angle postoperatively with a larger varus deformity of the knee preoperatively (p<0.0001). The corrective tibiofemoral angle had an increasing tendency with increasing bearing size but this was not statistically significant. Surgeons, the age of the patients, tibial translation, posterior slope of the tibial component, and coronary orientation of the tibial component and femoral component did not affect the degree of the corrective tibiofemoral angle. Conclusion: The average corrective angle of the tibiofemoral axis after minimally invasive UKA was 5.8°. The preoperative tibiofemoral angle and the types of implants affected the postoperative tibiofemoral axis after minimally invasive UKA.

박성호,김창우,정민영,박호근,허장원,정준권,배은환 대한골절학회 1999 대한골절학회지 Vol.12 No.1

The goals of the treatment of pilon fracture include to restore a normal anatomy and functional level of uninjured state. We analysed the clinical outcomes of the treatment of pilon fractures with calcaneal traction and percutaneous intramedullary nailing in the fibula (group A, 12 cases), or open reduction and internal fixation (group B, 11 cases) in 23 cases between April 1994 and March 1997. All of the patients were followed for at least one year (average, 18 months; range, 12 to 24 months). Fifteen patients were male (group A, 8; group B, 7), and eight were female (group A, 4; group B, 4). Falling-down injury is the most common cause and automobile accident is the second. According to the Ruedi and Allgower classification, type II fractures were most common. In the group A, two of the 12 fractures were type I, six were type II, and four were type III, and in the group B, two of the 11 fractures were type I, six were type II, and four were type III. According to the criteria of Mast and Teipner, in the group A, six were good result and six were fair, and in the group B, four were good, five were fair, and two were poor. A nonunion with wound infection and a malunion developed in the group B. The results in the group A were better than those in the group B in clinically, we propose the minimal surgical treatment is useful treatment option of pilon fracture.

The calcaneal fracture, which is considered to be the most common tarsal bone fracture, has rather difficulty in accurate diagnosis, classification and proper treatment. Furthermore, its prognosis is not good, either. The authors analysed 68 intraarticular calcaneal fractures (Sanders type II & III only) out of 147 cases, which were treated operatively or conservatively from June 1990 to May 1997, and found out that the results of conservative and operative treatment were approximately the same. The length of follow-up ranged from one year to four and half years (mean, 2.7years). The results were as follows: Of the 24 conservatively treated group, seven had excellent; eleven good; four fair; and two poor result. Of the 44 operatively treated group, eleven had excellent; twenty seven good; five fair; and one poor result. The sum of excellent and good results in conservative and operative treatment group were 75.0% and 86.4% each other, and these were not meaningful statistically (p=0.400). Therefore, the authors recommend a conservative treatment as an effective alternative method for the intraarticular calcaneal fracture.
