APPARATUS FOR CORRECTION OF PERIARTHRIC DEFORMATIONS OF LIMB BONES Russian patent published in 2008 - IPC A61B17/56 A61B17/60 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to traumatology-orthopedy, and is intended for treatment of periarthric varus-valgus deformations. Invention ensures correction of periarthric deformation of different limb segments. Apparatus contains upper and lower supports, intraosteal rods, rod fixator, remote fixator, threaded rods and arms. The said supports are made in the form of plates curved on radius in their plane with protrusions bent in this plane from end sections towards plate convexity. In the middle part along the above plates through oval slots are made. Protrusions and end sections of plates are furnished with holes, holes in protrusions being located towards periphery from holes in end sections. Rod fixators are made in the form of right prism placed on boss. The aforesaid prism has triangle in its base and through hole for intraosteal rod in long side of base. Boss is made with square cross-section and through threaded hole along vertical axis. Boss can be installed and fixed in the said slots by means of screw and washer. Remote rod fixator is made in the form of bar, which is furnished with a hole for intraosteal rod at its end, has thickness corresponding to width of the said slots and thread on narrow sides for nuts. Remote rod fixator can be fixed in aforesaid slots of lower support by means of nuts. In holes located in protrusions and end sections of lower support, threaded rods are mounted by means of nuts. On the opposite sides of the above threaded rods there are arms cross-coupled, by means of screw pairs, with arms fixed in end sections of upper support, forming plane link connection.

EFFECT: correlation of periarthric deformation of different limb segments.
