Purpose: To determine the radiographic changes in forefoot geometry with weight-bearing. Materials and Methods: The forefoot radiographs of 100 normal Korean adults, 50 male and 50 female volunteers, were evaluated both in nonweight-bearing and weight-bearing. The mean age was 27 years with range of 21-39 years. Those with normal feet were selected from volunteers having no history of foot problems or other musculoskeletal diseases. Results: The changes of measured angle between phalanges and metatarsals with weight-bearing were as follows; Hallux valgus angle was noted to increase in 20% of the feet, decrease in 59%, and remained unchange in 21%. Intermetatarsal angle $1{\sim}2$ was noted to increase in 76% of the feet, decrease in 3%, and remained unchange in 21%. Intermetatarsal angle $1{\sim}5$ was noted to increase in 95% and remained unchange in 5%. Shift in medial sesamoid on weight-bearing was also not consistent. Lateral shift was noted in 27%, no shift in 66%, medial shift in 7%. Conclusion: The generalized concept that the angles between bones and shift of medial sesamoid in the forefoot will change consistently with weightbearing was not found.

불안정성이 없는 슬관절과 전방십자인대 손상 슬관절에서 네비게이션을 이용한 슬관절 전후방 및 회전 안전성에 관한 생체 비교 연구
박상진 ( Sang Jin Park ),송은규 ( Eun Kyoo Song ),선종근 ( Jong Keun Seon ),허창익 ( Chang Ich Hur ),박기헌 ( Gi Heon Park ) 대한슬관절학회 2009 Knee Surgery and Related Research Vol.21 No.1
Purpose: We compared the anteroposterior translation and the internal-external rotation of the tibia in stable knees without an anterior cruciate ligament (ACL) injury with those of ACL injured knees by using a navigation system and we report the objective data. Materials and Methods: Forty-four patients who were treated for a meniscal tear without ACL injury were allocated to the stable group, and 41 patients were allocated to the ACL injury group. The anteroposterior displacement and the rotation of the knees were measured in 0, 30, 60 and 90 degrees of flexion with using the Orthopilot(R) navigation system. Results: The mean total rotation values were 18.8°±4.5°, 31.4°±4.2°, 30.1°±5.1° and 29.2°±5.9° at 0, 30, 60 and 90 degrees of flexion, respectively, in the stable group and 22.7°±6.9°, 37.6°±5.8°, 34.0°±9.4° and 31.8°±8.8° at 0, 30, 60 and 90 degrees of flexion, respectively, in the ACL injury group. Conclusion: The quantitative values for anteroposterior translation and rotations of stable and ACL injured knee were obtained using a navigation system.
