摘要

[Purpose] The purpose of this study was to examine the position of the distal fibula in subjects with sub-acute lateral ankle sprain (LAS) and to determine if a relationship exists between the amount of swelling and fibular position. [Subjects] The subjects participating in this study were ten patients with unilateral sub-acute LAS (the isolated anterior talofibular ligament injury: LAS group) and ten healthy persons (control group). [Methods] We measured subject%26apos;s fibular position and the amount of ankle swelling. The fibular position was measured as the distance between the lowest point of the lateral malleolus and the vertical line through the posterior margin of the calcaneus. Swelling was measured by the figure-of eight methods. [Results] The fibular position within the LAS group was significantly more anterior in the sprained ankles (43.7 +/- 8.3 mm) than in the contralateral uninjured ankles (38.8 +/- 7.6 mm). Additionally, sprained ankles were significantly more anterior than the side-matched ankle of the controls (37.4 +/- 4.2 mm). Spearman%26apos;s rank correlation coefficient revealed a positive correlation between fibular position and swelling (r=0.688). [Conclusion] The ankles with more swelling had a more anteriorly positioned fibula. This positional fault may be acutely maintained by the swelling.
