Abstract:
Objective To study the diagnostic value of achilles tendon injury(ATJ) and the diagnostic standards for different severities of the injury by MRI.Methods Twenty-six cases of traumatic ATJ proved both clinically and surgically and had complete MRI materials were selected.The characteristic MRI appearances were summed up and retrospectively compared with that of 10 normal achilles tendons.Results The results were as follows :(1) MRI appearances of 10 normal achilles tendons : regular course,smooth margin,homogenous hypointensity on T_1WI and T_2WI;(2) MRI appearances of 17 partial ATJs:tendon thickening,decreased ratio of wide/vertical diameter,localized hyperintensity in tendon on T_1WI and T_2WI,crude and irregular fibrous bundles but at least keeping one continuous layer on sagital view;(3) MRI appearances of 9 total ATJs: tendon thickened and irregular appearance,totally discontinuous fibrous bundles,"brush" or "pestle" change and mixed hyperintensity on T_1WI and T_2WI;(4) 7 cases with bone contrusion and soft tissue injury,2 cases with ligament injury,2 cases with bone and cartilage injury and 11 cases with fluid collected around tendon.Conclusion MRI can accurately judge thenature,range,degree and complications of ATJ and is of great value for preoperative plan of the treatment program and the postoperativeanalysis of the therapeutic effect.
