METHOD FOR LONGITUDINAL FLATFOOT TREATMENT Russian patent published in 2017 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: for the first version, the scaphoid bone and the medial malleolus, where channels are pre-formed, are fixed to each other, while the blind channel on the scaphoid bone is formed at the posterior end of the bone inwards, parallel to its articular surface. On the medial ankle, a blind channel is formed at its anterolateral margin from the bottom to the top at an angle of 40-45 degrees from the horizontal plane in the sagittal direction. A subcutaneous tunnel is formed between the channels. Then, one end of the flexible member is fixed by a fastening member in the channel on the medial ankle, a flexible latching member is guided through the formed subcutaneous tunnel. Foot supination is performed, while bringing together the medial malleolus and scaphoid bone to the distance of 20-25 mm between them, and the second end of the flexible latching member is fixed with the fastening member in the blind channel on the scaphoid bone. For the second version, a blind channel is formed in the scaphoid bone at the posterior margin parallel to its articular surface with an increased load on the medial ankle. A through channel is formed on the medial ankle up to the posterior surface of the tibia. A subcutaneous tunnel is formed between the channels. One end of the flexible member is fixed with a fastening member in the blind channel of the scaphoid bone. The flexible latching member is guided through the formed subcutaneous canal. Foot supination is performed, while bringing together the medial malleolus and scaphoid bone to the distance of 20-25 mm between them. The second end of the latching member is fixed with the fastening member in the through channel of the medial malleolus and additionally fixed on the posterior surface of the tibia by a trigger lock. Fastening members made from biodegradable, metallic, ceramic material are used. Anchor locks with thread fastening at the basis are used as fasteners. A flexible latching member made from a synthetic non-absorbable material in the form of a lavsan thread or tape is used.

EFFECT: methods eliminate foot pronation, reduce postoperative complications.
