Purpose: The purpose of this study is to find out the normal angles of the talus-1st metatarsal angle, the talo-horizontal angle and calcaneal pitch angle for diagnosis of foot deformity in Korea. This would be helpful as it would provide a basic angular measurement of flat and cavus foot that indicates the need for operation. Materials and Methods: Within a period of four months from January 2007 to April 2007, We have established 600 feet of 300 males without trauma history of foot. The source to image distance is 40 inches and erect weight bearing radiographs are obtained in anteroposterior and lateral projections. The significant angular measurements that define flat or cavus foot are the talus-1st metatarsal angle, the talo-horizontal angle and calcaneal pitch angle. Results: The mean age was 21 years (19-22 years) old. The mean talus-1st metatarsal angle was $0{\pm}6.9{^{\circ}}$, the mean talo-horizontal angle was $25.8{\pm}4.5{^{\circ}}$ and the mean calcaneal pitch angle was $23.9{\pm}5.1{^{\circ}}$. Conclusion: We can consider that mean talus-1st metatarsal angle, talo-horizontal angle and calcaneal pitch angle are $0{\pm}6.9{^{\circ}}$, $25.8{\pm}4.5{^{\circ}}$ and $23.9{\pm}5.1{^{\circ}}$ as an normal angle limit of young age in Korea.

Purpose: The aim of this study was to investigate the radiological characteristics of the osteoarthritis of the second metatarsophalangeal (MTP) and tarsometatarsal (TMT) joint. Materials and Methods: Between January 2002 and August 2010, 27 patients (33 feet) who had second metatarsal osteoarthritis (OA) were reviewed retrospectively. Group 1 was 14 patients (17 feet) with second MTP joint OA. Group 2 was 13 patients (16 feet) with second TMT joint OA. Group 3 was 24 patients (25 feet) had hallux valgus without second metatarsal (MT) OA as control. Weight bearing foot anteroposterior (AP) and lateral view were checked, and measured hallux valgus angle, metatarsus adductus angle (MAA), second MT functional length, first and second MT length by Hardy & Clapham method on AP view, angle of second MT with horizontal plane, calcaneal pitch, talo-first MT on lateral view. Results: On weight bearing foot AP view, second MT functional length of group 1, 2, 3 was 2.4 mm, -0.1 mm, 0.7 mm and MAA of group 1, 2, 3 was $17.7^{\circ}$, $17.7^{\circ}$, $14.5^{\circ}$. Second MT functional length of group 1 was longer than control group and it was statistically significant. MAA was significant different between group 1-3 and group 2-3. Angle of second MT with horizontal plane of group 2 was smaller than control group and it was statistically significant. Other radiographic parameters have no statistical significance. Conclusion: Group 1 has long functional length of second MT and group 2 has small angle of second MT with horizontal plane.

본 연구는 바닥에 치료용 깔창이 일체형으로 제작된 실내화를 이용한 유연성 편평족 환아의 착용 처치 전-후 임상 결과 및 영상의학 검사 결과에 대한 융합 연구이다. 유연성 편평족으로 진단받은 학령기 환아 35명에 대하여, 치료용 깔창이 일체형으로 제작된 실내화를 주중 5회 이상, 하루 4시간 이상 착용하게 하였다. 시행 전, 시행 후 제 4주째, 제 8주째, 영상의학 검사 및 FAOS 설문 조사를 시행하였고, 반복측정분산분석을 이용하여 통계 분석하였다. 임상 결과에서 FAOS 증상 항목과 통증 항목에서 통계적으로 유의한 향상이 관찰되었다. 영상의학 검사 결과에서 전후면 거골-제1중족각, 측면 거골-제1중족각, 거골-수평각이 호전되는 경향을 보이고 있었지만, 통계적 유의성은 찾을 수 없었다. 즉, 학령기 유연성 편평족 환아가 실내 생활 중 대부분의 시간 동안 치료용 깔창이 바닥에 일체형으로 제작된 실내화를 사용하는 것은 단기적으로 증상 완화 및 통증 경감에 효과가 있다.
