The ultrasound shows the apposition of tissue with varying degrees of echogenicity (from hypoechoic to iso-hyperechoic), which completely rehabilitates the area of discontinuity. Power Doppler hypervascularization patterns are not observed. The execution of the functional tests of concentric activation of the rectus abdominis (crunch and leg raise) highlights regular tensioning of the repair tissue with residual, minimal response to reduced resistance in the context of the hypoechoic tissue alone. The finding depicts the results of II-degree stabilized lesion (3B according to the Munich consensus 2012) of the left rectus abdominis in the stabilization phase
