65세 이상 여성 근위 대퇴골 골절 환자들에서 측정한 Singh Index의 신뢰도
유문집,박희곤,양석원 대한골다공증학회 2013 Osteoporosis and Sarcopenia Vol.11 No.1
Objectives: To evaluate osteoporosis in acute trauma situations, we compared reliability of Singh index values with bone mineral density in female patients older than 65 years with proximal femur fractures. Materials and Methods: We enrolled 145 patients who treated between June 2006 and May 2011. The radiograph was done and assessed by 3 observers to determine Singh index values. The reliability of Singh index was expressed in terms of intraobserver and interobserver agreements using Fleiss’s overall Kappa values, Pearson correlation coefficients, Kendall’s Tau-b values. Correlation of bone mineral density and Singh index was measured using linear by linear association. Results: Kappa values for intraobserver agreement ranged from 0.361 to 0.454. Kappa values for interobserver agreement ranged from 0.325 to 0.423 neither did not reach good reliability overall. There was no statistically significant correlation between Singh index and bone mineral density. Conclusions: Singh index is inappropriate method for clinic and research work due to poor interobserver agreement, though it is a simple and inexpensive method of assessing the osteoporosis in acute trauma patients.

Multiple fractures are becoming increasing due to traffic and industrial developments. Ipsilateral femur and tibia fractures are caused by high energy trauma and associated with many problems such as hemorrhagic shock, longer morbidity, delayed union of nonunion, knee stiffness etc. Recently the principles of treatment are directed to rigid internal fixation and early mobilization for more satisfactory functional recovery. Since July 1990, we managed 6 patients who had ipsilateral femur and tibia shaft fractures mainly with intramedullary nailing. The results are as follows ; 1. All the 6 cases were accompanied by multiple fractures and/or dislocations. Ipsilateral knee injuries were combined in 2 cases. 2. As for the femur, intramedullary nails were used in all cases. Intramedullary nailing was used for the tibia in 5 cases, and external skeletal fixator in the other one. 3. All the fractures united. Union time of the femoral fractures ranged from 6 to 8 months(mean : 29 weeks ; 6.7 months). Tibia shaft fractures united at from 14 to 32 weeks(mean : 22 weeks ; 5.2 months) postoperatively. 4. 3 Knees recovered full range of motion. But in the other 3 knees, limitations of further flexion to average 100 degrees were noted.
The Efficacy and Safety of Autologous Transfusion in Unilateral Total Knee Arthroplasty
유문집,박희곤,류지원,김정상 대한슬관절학회 2015 대한슬관절학회지 Vol.27 No.3
Purpose: Although allogeneic blood transfusion is the most common method of transfusion in total knee arthroplasty (TKA), there are reports showing significant decrease in the amount of allogeneic transfusion and incidence of side effects after combined use of autologous transfusion. The purpose of this study is to investigate the efficacy of using an autologous transfusion device in TKA.Materials and Methods: Patients who underwent TKA at our institution from January 2003 to January 2014 were divided into two groups: group A (n=127) who received allogeneic transfusion only in TKA and group B (n=118) who received autologous transfusion via an autologous transfusion device and allogeneic transfusion. In both groups, the patients were transfused when the hemoglobin level was below 9 g/dL. In group B, blood collected by the autologous transfusion device was transfused only once after surgery. The total blood loss volume, total transfusion volume, and the presence of side effects were assessed based on medical records.Results: Group A received 294.6 mL more allogeneic transfusion than group B (p<0.001). There were no significant differences with regard to the development of side effects between groups.Conclusions: Application of an autologous transfusion device during TKA can be effective in reducing the allogeneic transfusion volume. Moreover, allogeneic transfusion was not necessary after autologous transfusion in some patients.

Purpose: To provide basic data on anatomy of the ankle joint in adults using magnetic resonance imaging as well as to compare measurements with available data of corresponding dimension in the different sizes of the total ankle replacements design ($HINTEGRA^{(R)}$). Materials and Methods: Magnetic resonance (MR) sagittal and coronal images from one hundred-forty nine were studied. Post traumatic, arthritic, or grossly deformed ankles at any reason were excluded. Lengths, widths of the main parts of this articulation and also the radius of curvature of talar dome were measured in the MR images. Statistical analysis was performed on these measurements. Results: On MR coronal image data, average tibial width was $30.0{\pm}4.1\;mm$ and talar width was $27.0{\pm}3.4\;mm$. On sagittal image date, average anteroposterior length of the distal tibia was $39.0{\pm}4.2\;mm$, average anteroposterior length of the talus was $31.3{\pm}2.8\;mm$, and average sagittal radius of curvature of talar dome was $20.1{\pm}2.9\;mm$. All measurements in male were significantly larger than in female (p<0.01), but a significant difference according to age was not found. Conclusion: Ankle morphometric data define a basis of size, particularly useful in the design of ankle prostheses.
정상체중성인과 과체중성인의 거골-제1종족골 및 종골하면-제1종족골하면 관절간 각도 차이에 대한 연구

Normal feet have the longitudinal arch for the distribution of the weight. The longitudinal arch is known lateral and medial longitudinal arch. Collapsed arch of the foot is flat foot and it is the cause of the foot pain. Of course the low arch does not always make a foot problem in sports and daily activity. Longitudial foot arch is visible in the standing foot lateral radiograph, Harris mat and visual observation. In Radiographic study the lateral Talo-lst Metatarsal angle is known in standing foot lateral film. But the longitadinal medial arch is not correctly obtained in Talo-lst Metatarsal angle. So this study for Calcaneo-lst metatarsal angle in standing lateral foot radiograph is more valuable angle in medial longitadinl arch. And we do the study on difference in the longitadinal arch in normal weight versus overweight person.

Angular deformities of the distal femur occur in congenital diseases or due to acquired causes, such as malunion after a fracture of the distal femur. Angular deformities of the lower extremities affect the mechanical axis, causing changes in the weight pressure on the articular surface. As a result, angular deformities quicken the progression of osteoarthritis. Therefore, correction of deformities should be performed to prevent the progression of osteoarthritis. Distal femoral osteotomy is one of the methods to correct angular deformities in unicompartmental osteoarthritis. However, femoral supracondylar dome osteotomy with retrograde intramedullary nailing in the distal femur with a varus deformity has been rarely reported. Herein, we describe a technique for femoral supracondylar dome osteotomy with retrograde intramedullary nailing in a varus deformity after a pathologic fracture of giant cell tumor in the distal femur with a review of the relevant literature.
