METHOD FOR AUTOTENDOPLASTY IN ACHILLES TENDON DEFECTS Russian patent published in 2024 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to traumatology, can be used in treating Achilles tendon defects. Longitudinal approach is made along the posterior surface of the shin, outside the Achilles tendon defect, in a projection of the proximal stump of the Achilles tendon, not more than 5 cm long. Tenolysis and freshening of proximal stump of Achilles tendon are performed. Proximal stump is brought out into the wound, stitched with a locking two-strand Krakow suture. A longitudinal incision is made posteriorly from an external malleolus, a tendon of a peroneus longus muscle is separated. Graft is formed from the tendon of the peroneus longus muscle of the tendon. Graft is collected using a stripper along the entire length of the tendon of the peroneus longus muscle. Distal end of the graft is sutured with a locking two-strand suture. Two incisions-punctures 1 cm long are made along inner and outer surfaces of calcaneal bone in projection of calcaneal tuberosity. Canal is drilled in the calcaneal bone, which is oriented in a frontal plane. Sutured end of the graft is delivered through the formed canal, delivered along the distal stump of the Achilles tendon in the direction of the proximal stump of the Achilles tendon, and the sutured end of the graft is brought out into the wound along the posterior surface of the shin. Sutured end of the graft and the proximal stump of the Achilles tendon are sutured end to end. Required length of the graft is re-evaluated in a stretched condition of the graft with a functionally advantageous position of the foot. Second end of the graft is excised and stitched with a locking two-strand suture; the second stitched end of the graft is delivered along the distal stump of the Achilles tendon in the direction of the proximal stump of the Achilles tendon and brought into the wound along the posterior surface of the shin. Locking four-strand suture of the proximal stump and two ends of the graft is formed; toilet of wounds and layer-by-layer closure.

EFFECT: method provides the optimum ratio of strength and spatial characteristics of the Achilles tendon graft with less disturbance of the soft tissues in the area of the Achilles tendon defect due to minimally invasive replacement of Achilles tendon defect with autotendograft from one anatomical zone located outside the defect zone.
