We describe an innovative mini-open technique for reinsertion of the flexor digitorum profundus tendon under Wide Awake Local Anesthesia No Tourniquet (WALANT) with ultrasound assistance. Ultrasound-aided detection at the surgeon's practice is used to plan the surgical tendon repair procedure so that tendon reinsertion can be performed with the smallest incision possible. Passage of the tendon through the digital sheath was accomplished with the help of a compressive tendon guide to avoid a surgical approach. Reinsertion of the tendon under WALANT monitoring enables intraoperative validation of repair tension and physiological restitution of tendon glide within the digital sheath. Postoperative ultrasonographic examination at the surgeon's practice is an occasion to further patient education begun intraoperatively under WALANT., (Copyright © 2021 SFCM.

Closed rupture of the thumb flexor tendon pulleys is rare. Although anatomical and biomechanical studies have exposed the roles played by the pulleys in flexor pollicis longus (FPL) function, no standardized surgical management has yet been defined, in contrast to situations where pulley reconstruction is required in the fingers. We describe a case of rupture of the three pulleys in the thumb that probably occurred after violent thumb grasp during childbirth in the absence of any other trauma. We reconstructed the A1 pulley only using an extensor retinaculum graft because no remnants of the native pulleys were present., (Copyright © 2018 SFCM. Published by Elsevier Masson SAS.
