윤호현,윤정로,유중진,서효성 대한고관절학회 2014 Hip and Pelvis Vol.26 No.3

Purpose: To evaluate the usefulness of navigated acetabular cup fixation for total hip arthroplasty in patientswith acetabular deformity or revision total hip arthroplasty. Materials and Methods: This study enrolled 28 patients with at least 12 months’ follow-up. The safe zone ofthe acetabular cup was defined as 40。±10。in inclination and 15。±10。in anteversion. The authors used thenavigation and radiographic data to determine whether the acetabular cup was located within the safe zone ornot. To evaluate the clinical outcomes, preoperative and last follow-up Harris hip scores were checked, and theoccurrence of complications was evaluated. Results: According to the navigation data, the mean inclination and anteversion were 38.5。±4.7。(range, 32。-50。) and 16.6。±4.0。(range, 8。-23。), respectively. According to the radiographic data the mean inclination andanteversion were 40.5。±4.6。(range, 32。-50。) and 19.4。±4.2。(range, 8。-25。), respectively. In both cases, allvalues were within the safe zone. Harris hip score was improved in all patients from preoperative 52.3±14.4points (range, 29-87 points) to 88.0±9.0 points (range, 65-99 points) at the last follow-up. There was nodislocation or loosening of both cases. Conclusion: Navigated acetabular cup fixation is a useful technique for total hip arthroplasty in patients withacetabular deformity or revision total hip arthroplasty because it prevents the malposition and related complications.

Subtrochanteric Femoral Fracture during Trochanteric Nailing for the Treatment of Femoral Shaft Fracture

윤호현,Chi Hun Oh,Ju Won Yi 대한정형외과학회 2013 Clinics in Orthopedic Surgery Vol.5 No.3

We report on three cases of subtrochanteric femoral fractures during trochanteric intramedullary nailing for the treatment of femoral shaft fractures. Trochanteric intramedullary nails, which have a proximal lateral bend, are specifically designed for trochanteric insertion. When combined with the modified insertion technique, trochanteric intramedullary nails reduce iatrogenic fracture comminution and varus malalignment. We herein describe technical aspects of trochanteric intramedullary nailing for femoral shaft fractures to improve its application and prevent implant-derived complications.

과제 수행 중심의 말하기 지도 방안 : 「말이 트이는 한국어」를 중심으로 Based on 「Pathfinder in Korean」

현윤호 국제한국어교육학회 2001 한국어 교육 Vol.12 No.2

The objective of this study is to propose a task-based approach for teaching Korean speaking as a second language. More specifically, the organization of task-based teaching materials and systematic teaching methods considering the unique characteristics of Korean are presented. To accomplish this objective, the characteristics of Korea speaking are examined with the analysis of the factors that make Korean speaking difficult. A Korean speaking teaching aid, 「Pathfinder in Korean」, is used to put together a detailed teaching method. It is found that the most difficult part of speaking is to understand and learn the nature of interaction in verbal communication. What is said, when and how it is said, and to whom it is said have strong influence on the language use. Therefore, an instructor has to organize the teaching materials and methods to help students understand the nature of interaction. This study suggests a task-based approach that reflects the importance of interaction as an effective tool for Korean speaking instruction.

Purpose: The purpose of this study was to evaluate the usefulness of our method, which estimated femoral stem alignment using a c-arm when the broach was inserted, for prevention of femoral stem malalignment. Materials and Methods: A total of 103 hips were enrolled in this study. All patients underwentprimary hip arthroplasty from October 2011 to February 2013. The study was conductedretrospectively. Intraoperative estimated femoral stem alignments and final femoral stem alignments were classified into three groups. Multinomial logistic regression analysis was performed for analysis of factors (age, sex, diagnosis, body mass index, femoral stem size, osteoporosis, and proximal demur geometry) thatmight affect intraoperatively estimated femoral stem alignment. Results: The distribution of intraoperative estimated femoral stem alignment was 80(78%) in the neutral group, 18(17%) in the varus group, and 5(5%) in the valgus group. The distribution of final femoral stem alignment was 100(97%) in the neutral group, 2(2%) in the varus group, and 1(1%) in the valgus group. There was no statistically significant factor affecting the intraoperatively estimated femoral stem alignment. Conclusion: Intraoperative estimated femoral stem alignment using a c-arm is an effective method for prevention of femoral stem malalignment.
