Purpose: To determine the locations and incidences of sesamoids and accessory bones of the forefoot in normal Korean adults. Materials and Methods: The plain radiographs of the forefoot of 400 volunteers, 200 males and 200 females, were taken. The three orthopedic surgeons participated in the radiographic evaluation independently. Persons who had history of foot problem or injury were excluded. Results: Sesamoids of first metatarsophalangeal joint were nearly always present; medial 99% and lateral 100%. The bipartite sesamoid was more common in medial (9.8%) and in female (17.0%) than in lateral (0.3%) and in male (2.5%). Sesamoids of the interphalangeal joint of the first toe were seen in 35.8%. Sesamoids of metatarsophalangeal joints in other four toes were rarely observed. Their incidences were 5% in second toe, 0.8% in third, 0% in fourth, and 2.8% (lateral) and 7.5% (medial) in fifth. Sesamoids of interphalangeal joint in four lesser toes were not observed except two cases (0.5%) in the fifth toe. Accessory bone was very rarely observed. Os vesalianum was observed in five feet (1.3%), Os intermetatarseum in 14 feet (3.5%), and Os cuneo-metatarsal I tibiale in none. Conclusion: We determined the location and incidences of sesamoids and accessory bones of the forefoot, and we expected this to help to diagnose the forefoot problem.

목적: 전방십자인대 재건술의 수가 증가하면서, 재건술의 실패로 인한 재재건술의 빈도 또한 증가하고 있다. 따라서 저자는 전방십자인대 재건술 후 발생한 이식건 실패의 원인 및 전방십자인대 재재건술 후의 임상적 결과를 분석하였다. 대상 및 방법: 1998년 2월부터 2010년 7월까지 전방십자인대 재건술 실패에 대하여 전방십자인대 재재건술을 시술받은 후 최소 12개월 이상 추시가 가능하였던 36예를 대상으로 하였다. 재건술 후 재재건술까지의 평균기간은 60(5~334)개월이었으며, 처음 전방십자인대 재건술을 시술 시 23예(63.9%)에서 동종 이식건을, 13예(36.1%)에서 자가 이식건을 사용하였다. 전방십자인대 재건술 실패의 주증상으로 불안정성이 가장 많았으며, 전방십자인대 재건술을 한번 시행 받았던 경우가 35예(97.5%), 두 번 시행 받았던 경우가 1예(2.5%)였다. 임상적 결과는 Lysholm 슬관절 점수, Tegner activity 점수를 이용하여 평가하였으며, 안정성은 Lachman 및 pivot shift 검사와 Telos device를 이용하여 평가하였다. 결과: 환자의 평균 추시 기간은 21(12~40)개월이었으며, 전방십자인대 재건술의 실패원인으로는 외상이 19예(52.8%)로 가장 많았고, 대퇴 터널의 부정위치가 13예(36.1%), 경골부 터널의 부정위치가 1예(2.8%), 골융합의 실패 3예(8.4%)로 나타났다. 전방십자인대 재재건술을 시행할 시 34예(94%)에서 동종이식건을, 2예(6%)에서 자가 이식건을 사용하였으며, 21예에서 반월상 연골판 손상이 동반되었다(내측 반월상 연골판 손상 14예, 외측 반월상 연골판 손상 7예). Lysholm 슬관절 점수는 술전 66.5점에서 술후 최종 추시시 92점으로 호전되었다(p<0.01). 환자의 대부분은 수술 결과에 만족(92%)하고 있었다. Tegner activity 점수는 술전 2.0점에서 술후 6.2점으로 호전되었다(p<0.01). Lachman 및 pivot shift 검사에서 33예, 30예가 Gr I 이하로 호전되었으며, Telos device를 이용한 안정성 검사에서는 양측 차이 정도는 술전 평균 15.5 mm에서 술후 최종 추시시 4.5 mm로 의미있게 호전되었다(p<0.01). 환자의 대부분은 수술 결과에 만족(92%)하고 있었다. 결론: 전방십자인대 재 재건술은 1년 이상 추시 결과 약간의 전방 불안정성이 존재하였으나, 임상적 결과 및 환자의 주관적 만족도에 있어서는 우수한 결과를 보였다. Purpose: As the number of the anterior cruciate ligament (ACL) reconstruction has increased, the incidence of revision of ACL reconstruction due to reconstruction failure has been also increased. Therefore, authors analyzed the reason of the failure of ACL reconstruction and the clinical result of the ACL revision. Materials and methods: From February 1998 to July 2010, we selected 36 cases which was followed at least 12months after the ACL reconstruction failure. Duration from reconstruction to revision, the average duration was 60 months (5~334) and on first reconstruction, we used allograft on 23 cases (63.9%) and autograft on 13 cases (36.1%). For the main symptom of ACL reconstruction failure, instability was the most common symptom, and 35 cases (97.5%) were undergone only one reconstruction and 1case (2.5%) was undergone two reconstruction. Clinical results were evaluated by Lysholm knee joint score, pivot shift test, and Telos device. Results: Average follow-up duration of the patients was 21 months (12~40), and the reason for the ACL reconstruction failure, trauma was most common by 19 cases (52.8%), malposition of the femoral tunnel was 13 cases (36.1%), malposition of the tibia tunnel was 1case (2.8%), and failure of osteointegration was 3 cases (8.4%). On performing the ACL revision, we used allograft on 34 cases (94%) and autograft on 2 cases (6%), and 21 cases accompanied injury of the meniscus (medial meniscus 14 cases, lateral meniscus 7 cases). Lysholm knee joint score was improved from 66.5 points, preoperatively to 92 points on last follow-up (p<0.01). In most cases, patients were satisfied (92%) with the operation results. Tegner activity score was also improved from 2.0 points preoperatively to 6.2 points on the last follow-up. On Lachman and pivot sift test, 33 cases and 30 cases were improved to grade I respectively, and on stability test using Telos device, the bilateral difference was improved from mean 15.5 mm preoperatively to 4.5 mm on the last follow-up. Conclusion: After 1 year follow-up, Revision of ACL had a little anterior instability but it showed satisfactory result on clinical result and patient's subjective satisfaction.

The objective of this study is to propose an integrated lifting model of planning and operation for finishing works in tall building construction. The model consists of five components: lifting schedule chart, lifting load leveling, lifting equipment planning, lifting TACT and lifting table. The model was designed to provide a more practical lifting planning and operating method for construction managers as well as to cope with unexpected schedule delays. To validate the proposed model, a case study was performed in building a construction project; questionnaires were distributed in order to evaluate its effectiveness compared with the original method. A case study showed the following results. (1) The model is estimated to provide more practical lifting planning alternatives compared with the original method to construction managers. (2) The model can be a valuable management tool in terms of the lifting operation of construction lift. (3) The model can be provide an effective method to cope with unexpected situations through the integration of lifting planning and operation. Therefore, It is expected that the proposed model can be employed as practical means to the planning and operation of construction lift at construction sites.

송은규,선종근,김형순,강경도,변재욱,Song, Eun-Kyoo,Seon, Jong-Keun,Kim, Hyung-Soon,Kang, Kyung-Do,Byun, Jae-Wook Korean Orthopaedic Society for Sports Medicine 2010 대한정형외과스포츠의학회지 Vol.9 No.1

목적: 자가 골-슬개건-골과 자가 슬괵건을 이용한 전방 십자 인대 재건술 후, 골관절염의 발생률과 위험인자를 비교하고자 하였다. 대상 및 방법: 8년 이상 추시가 가능하였던, 자가 슬개건 53예 및 자가 슬괵건 40예를 이용한 전방 십대 인대 재건술을 시행한 총 93예를 대상으로 하였다. Kellgren and Lawrence의 분류에 따라 방사선상의 골관절염의 변화를 관찰하였고, 슬관절의 임상적 기능 (Lysholm 슬관절 점수, Tegner 운동 지수), 신체검사상의 전방 이완 정도 (Lachman 검사, Pivot-Shift 검사) 및 $Telos^{(R)}$ 기구를 이용한 전방 이완 정도를 비교 평가하였다. 결과: 자가 골-슬개건-골을 이용한 대상 중 24예 (45.3%)에서, 자가 슬괵건을 이용한 대상 중 14예 (35.0%)에서 방사선 검사상 골관절염 변화가 확인되었다. 동반된 연골판 손상 (골-슬개건-골 군 p<0.001, 슬괵건군 p=0.091), 수상에서 재건술까지 12개월 이상 경과 (골-슬개건-골 군 p=0.037, 슬괵건 군 p=0.021), 재건술 당시 연령 25세 이상 (골-슬개건-골 군p=0.003, 슬괵건 군 p=0.048) 등이 골관절염의 유의한 위험 인자로 나타났다. 하지만, 골관절염의 발생과 임상적 결과, 방사선적 안정성과의 연관성은 없었다. 결론: 자가 골-슬개건-골 및 자가 슬괵건을 이용한 전방 십자 인대 재건술 후 평균 10년 추시상 두 군 모두에서 임상적으로 양호한 결과를 얻었으나, 상당한 비율에서 방사선적 골관절염 변화가 관찰되었다. 또한 동반된 연골판 손상, 수상 후 재건술까지의 지연된 시간, 25세 이상의 연령 등의 다양한 인자가 이에 관련됨을 알 수 있었다. Purpose: To compare the incidence and risk factors for osteoarthritis after anterior cruciate ligament (ACL) reconstruction between two groups using bone-patellar tendon-bone (BPTB) and hamstring tendon (HT) autograft. Materials and Methods: 53 cases of ACL reconstruction using patellar tendon and 40 cases using hamstring tendon were followed up at least 8 years. Radiographic evaluation was done according to the Kellgren and Lawrence's classification. Clinical functional testing (Lysholm Knee Scores, the Tegner activity scores) and laxity testing (Lachman, pivot shift tests), and the instrumented laxity testing with $Telos^{(R)}$ were all examined in relation to the development of osteoarthritis. Results: Radiographic osteoarthritic changes were detected in 24 patients (45.3%) in BPTB group and 14 patients (35.0%) in HT group. Accompanying meniscal injury (BPTB p<0.001; HT p=0.091), intervals from the injury to reconstruction of > 12 months (BPTB p=0.037; HT p=0.021), and patient's age at reconstruction of > 25 years (BPTB p=0.003; HT p=0.048) were found to be significant independent predictors of osteoarthritis. However, no statistically significant correlations were found between the development of osteoarthritis and the clinical outcome or the radiographic stability in both groups. Conclusion: Although ACL reconstruction using BPTB or HT autograft had good clinical results at an average follow-up of 10 years, considerable incidence of radiographic osteoarthritic changes were noted. Various factors such as accompanying meniscal injury, protracted time from injury to reconstruction, more than 25 years old at the time of reconstruction were related to radiographic osteoarthritic changes.

Recently, domestic housing market copes with the transition from a supplier-oriented market to a customer-oriented one due to the various customer needs, the growth of the housing supply ratio, and the changes in housing regulations. In the customer-oriented environment, construction companies try to develop the various strategies satisfying the customers for competitiveness. Efficient defect repair and maintenance is one of the key strategies because the defects after movement into a new house make directly residents unsatisfied. Especially, quality and performance of apartments by efficient defect management influences increasingly on asset values of apartments. However, many previous studies have been concerned with defect types and frequencies, and management system instead of repair and maintenance costs. Therefore, the objective of this paper is to indentify and analyze items of defect repair and maintenance costs and to assess the impacts of each item on entire defect repair and maintenance costs by factor analysis. The result will contribute to assist construction company in developing an efficient defect repair and maintenance scheme for customer satisfaction.
