Biceps Femoris Fibrosis

about ultrasound monitoring of muscle injury remodelling phase

In my recent post Ultrasound Muscle Injuries Monitoring I showed the importance of the dynamic ultrasound and elastosonography exam in the study of the granulation tissue at the site of injury during the rehabilitation program.

Today I want to remind you to take care about muscle also after the final phases of remodeling (3–6 months after trauma), in which maturation of the regenerating fibers into a functional contractile unit takes place.

Axial (left) and Coronal (right) Mri scans of a late left biceps femoris injury evaluation (1.5 Tesla).

In these cases the Mri exam is less sensistive than ultrasound imaging; don’t forget to always perform both imaging modalities.

The patient suspected a reinjury in the same site of a previous trauma; first evaluation was made with an ultraportable device.

The power-doppler exam togheter with the elastosonography evaluation, show an incomplete scar maturation.
