case_images: The ultrasounds examination shows an irregular region (arrow) of the flexor digitorum superficialis tendon suggestive of a partial rupture, accompanied by the thickening of the pulley A1 (asterisk). P: Proximal Phalanx; M: Metacarpus; MPJ: Metacarpo-Phalangeal Joint.

case_images: The feeling of numbness just under the scar, the first steroid injection that was not effective and the young age of the patient, led us to perform an ultrasound examination of the hand tendons (Figure 1), which showed a suspect tear of the flexor digitorum superficialis tendon of the ring finger, proximally to the pulley A1 that appeared thickened.
case_images: The picture shows the longitudinal partial flap-shaped tear of the flexor digitorum superficialis.

case_images: A1 and extended Brunner-like proximally in direction of the scar. A partial longitudinal flap-shaped tear was discovered, large approximately half of the entire tendon diameter, of the radial half of the flexor digitorum superficialis tendon that hooked at the entrance of the A1 pulley (Figure 2).
