During walking, at the end of the stance phase, before the foot looses contact with the substrate(swing phase), the foot makes a small inversion movement while the lower leg shows external rotation. Insight in this particular movement is necessary, to better understand pathologies concerning this inversion movement such as inversion traumatisms. Methods: Performing a study on ten anatomical specimens of human lower legs, we carried out measurements on tracings, made of X-ray pictures of the specimens. X-rays were taken with lower legs in three subsequent conditions: normal stance phase, push-off (inversion) and extreme inversion. In each foot, reference marks (metal screws, 'intracortical' pins) were inserted in the first metatarsal bone at standardized positions. The metal screws are visible on the X-rays. Based on length changes of the projections of these screws on the X-rays, rotation angles of the first ray during push-off were calculated. Results: Measurements show that in anatomical specimens at the position of push-off, the average rotation of the first metatarsal around its longitudinal axis, measured distally, amounts 9°. Conslusion: On the basis of the present investigation it can be concluded that the first ray of the foot, measured distally at the level of the first metatarsal bone in anatomical specimens, performs a small rotation movement around its longitudinal axis during the push-off phase of the gait cycle. Further research will be needed. | Notes: | Date: October 31 - November 1, 2007 | Keywords: | Foot, Anatomy, Inversion movement | Document URI: | http://hdl.handle.net/1942/7734 | Link to publication/dataset: | http://www.med.pu.ru/2008/pdf/pr_hir.pdf | ISBN: | 978-5-288 04434-2 | Category: | C1 | Type: | Proceedings Paper |
