MRI Diagnosis Of The Spring Ligament Injury Of Amateur Marathon Athletes And Analysis Of Injury Factors Of Foot Arch

Objective:By using magnetic resonance imaging to analyze the display and injur y performance of amateur marathon athletes’ spring ligaments on MRI,and analyz e the influencing factors of foot arch damage.Methods: Thirty normal volunteers,aged 25-46 years,with a monthly running vol ume of 7-30 km,were selected as the control group;60 amateur marathon runners,aged 27-48 years old,with a monthly running volume of 80-400 km were selecte d as the test group.The general data and spring ligaments MRI performance of t he control group and the test group were compared.Logistic regression analysis e xplored the influence of athletes’ monthly running volume,posterior tibial tendon,anterior tibial tendon,fibula strain,and ankle traction test on the test group’s foo arch.Result: There were no statistical difference in the general data of gender and age between the two groups(P>0.05).The imaging analyses of the superomedial ca lcaneonavicular ligaments in the test group were significantly higher than those in the control group,and the differences were statistically significant(P<0.05).Comp ared with the control group,there were no significant difference in the medioplant ar oblique calcaneonavicular ligaments between the test group and the control gro up(P>0.05).Logistic regression analyses show that monthly running volume was an influencing factor for athletes’ arch damage,and the greater the monthly runni ng volume,the more severe the athlete’s arch damaged.Conclusion: Spring ligament injury was a common ligament injury in amateur ma rathon athletes,MRI could effectively diagnose the spring ligament injury.The fo ot arch injury of amateur marathon athletes was closely related to the repeated an kle joint injury caused by the extensive running.
