METHOD FOR BIARTICULAR ARTHRODESIS OF ANKLE AND TALOCALCANEAL JOINTS WITH LOCK NAIL, AND BONE GRAFTING WITH ADVANCED AUTOGRAFT Russian patent published in 2015 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: cortical-spongious autograft sawn out along an anterior surface in a lower one-third of shin bone at a depth to an opposite cortical plate of the shin bone and extending onto an ankle bone to a posterior articular surface of the talocalcaneal joint is formed. The autograft is modelled to re-shape the nail surface to ensure a tight contact thereto. Bone autochips are placed into the processed posterior portion of the talocalcaneal joint, and an intramedullar rod is inserted and locked. A tibial autograft is adapted to the nail, and using a press-fit effect provides moving into the ankle bone with overlapping the ankle joint. Fragments of the ankle bone of the autograft are used to fill the form the defect of the shin bone above the shin bone of the autograft displaced downwards.

EFFECT: forming the strong tibial-talocalcaneal block, reducing the length of treatment, and restoring the support ability of the extremity.
