METHOD FOR SURGICAL MANAGEMENT OF ARTICULAR COMPRESSION FRACTURE OF CALCANEUM AND BRACKET FOR IMPLEMENTING IT Russian patent published in 2014 - IPC A61B17/00 A61B17/56 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely to traumatology and orthopaedics for managing articular compression fractures of calcaneal bones. After the calcaneal bone is approached, fibrous canals of the fibular tendons are opened and moved upwards. Calcaneofibular and talocalcanean ligaments are dissected away; a subtalar joint capsule is opened, and a subtalar joint is exposed. A flap of the bone is separated en bloc with a periosteum, a cortical plate and a spongy bone. The bone fragments are reduced with using a mouth expander with a ratchet. A porous titanium nickelide implant in the form of a hollow octagonal rod filled with an autograft or osteoplastic material is introduced into the bone. There are used two memory-shape brackets made of an L-plate a long leg of which has an arched curve and a short leg of which is inclined at 45 degrees and is hook-ended. The long leg of one bracket is introduced into the canal formed through the bone fragment of a calcaneal knot, a median intra-articular fragment and partially through an ankle. A short leg is inserted into a calcaneal knot canal formed below an input of the long leg canal. The long leg of the other bracket is inserted into a canal passing through the calcaneal knot and the bone fragments along a plantar contour of the calcaneal bone, while the leg is inserted into the calcaneal knot. After the bracket strain recovers, the arch of the upper bracket is opened upwards, and the arch of the lower bracket is opened downwards; the hook of the short leg of both brackets is directed and rests from the inside into the cortical plate of the calcaneal knot.

EFFECT: method and device for implementing it provides the durable stabilisation of the bone fragments.
