Fig. 1From: Correlations of magnetic resonance imaging classifications with preoperative functions among patients with refractory lateral epicondylitisExamples of MRI findings on the origin of the ERCB, the grades are same within the three classifications. A 44-year-old male, MRI showed grade 1 injury on the origin of the ERCB (focal or mild increased signal intensity). B 48-year-old female, MRI detected grade 2 injury on the origin of the ERCB (Moderate increased signal intensity, comprise less than 50% of the tendon thickness). C 52-year-old female, MRI detected grade 3 injury on the origin of the ERCB (Severe increased signal intensity, comprise more than 80% of the tendon thickness) (black arrow)Back to article page
