METHOD OF CLOSED INTRAMEDULLARY OSTEOSYNTHESIS OF SHIN BONE Russian patent published in 2009 - IPC A61B17/58 

FIELD: medicine.

SUBSTANCE: invention concerns medicine, namely to traumatology and orthopedy and can be used for treatment of fractures of a tibial bone. A spoked distracter, consisting of a half-ring and a ring or a half-ring is used, bridged by three telescopic hinges and pivotally fixed on the half-ring from two telescopic hinges bridged on other extremity by a lath for reposition of fragments. Thus a half ring the ring or a half ring at level of a distal metaphysis have at level of a proximal metaphysis of a tibial bone in front, and. Spokes are spent on one in a face-to-face plane to proximal and distal metaphyses of a tibial bone, thus a proximal spoke have in a back semicircle of the bone. The spokes are fixed in the distracter, and distraction is spent on telescopic hinges. After restoration of length of a segment a knee joint incurvate to an acute angle and fix an extremity in this position by means of a support then enter an intramedullary nail. At fractures of proximal department of a tibial bone for a shift exception under an angle opened to the behind at flexion of the knee joint in addition spend a spoke in a face-to-face plane for a crest of a tibial bone to front from the medullar channel as much as possible close to the bottom extremity of a proximal fragment, pull and fix on a half ring to a flexion in a knee joint. Spend three rejecting spokes to an exit from the second wall of an osteal tube: face-to-face to the inside to the front to the outside, two sagittal in front back also enter intramedullary a nail to front from a face-to-face spoke, to the front from proximal and to the inside from the distal sagittal spokes. At distal fractures for simultaneous restoration of length of both bones to a distraction an external malleolus fix an additional not through spoke to an interfacing bone, and at fractures at level of a cleft of an ankle joint an external malleolus fix to the huckle bone. For correcting of valgus or varus shift of position of fragments two rejecting not through spokes spend to a distal fragment in a frontback direction. For elimination of valgus shift a nail is spent outside from proximal and to the inside from a distal spoke. For elimination of varus shift - to the inside from proximal and to the outside from distal spokes. For elimination of antecurvation or recurvations in a distal fragment two rejecting not through spokes in a face-to-face plane from within the outside spend, and a nail is spent at antecurvation to front from proximal and behind from distal spokes, and at a recurvation - to the behind from proximal and to front from distal.

EFFECT: invention can be used for treatment of fractures of a tibial bone.
