METHOD OF SHANK ELONGATION IN DOGS Russian patent published in 2014 - IPC A61B17/56 A61B17/58 A61B17/00 

FIELD: veterinary medicine.

SUBSTANCE: Z-shaped tenotomy of tendon ends of muscles of the rear surface of the shank is carried out, the intimately connected bundles of the tendons of the gastrocnemius muscle and flexor digitorum sublimis are isolated. Then they are crossed at sliding movement of the skin incision, made from the caudal surface of the Achilles tendon. At that first the Achilles tendon is incised in the area of the muscle-tendon junction, then the sublimit tendon, departing distally at a distance corresponding to the value of the elongation, keeping the additional tendon. The flexion efforts to ankle joint are made to the position of the ends of the incised tendons end to end, the soft tissues are sutured, after osteosynthesis by Ilizarov frame and solution of continuity of shinbones the elongation of the shank is performed with the rate of 3 mm per day for 120 manoeuvres, with a single step of spreading the fragments by 0.025 mm for 10 days to obtain a regenerated cartilage with the height of 30 mm.

EFFECT: reduction of the frame period and prevention of formation of equinus foot position and flexion contracture of the ankle joint in elongation of shank in dogs due to optimum tenotomy and auto distraction mode.
