ORTHOPAEDIC APPARATUS FOR VALGOID BOW LEG ELIMINATION Russian patent published in 2010 - IPC A61F5/01 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to orthopaedics, and aims at valgoid bow leg elimination in children and adolescents. An orthopaedic apparatus comprises fasteners to limb segments pivotally connected along the axis corresponding to the joint motion axis rotatable about axis. Said fasteners represent demountable sleeves, one for each segment. On the opposite lateral surfaces of the sleeves, along the longitudinal axes, there are splints each of which have fixed two arms for threaded bars. The bars are equipped with flats along the full length. One arm is fastening, and an aperture therein corresponds to a cross-section contour of the threaded bar, in the middle of this arm, there is a groove for nut rotatable on the treaded bar. The other arm is guide and has a parallel hole. The adjacent ends of the bars of the fasteners are pivotally connected to the axes, each of which is radially mounted on one of two cylindrical plates fastened in the centre with the threaded joint, herewith forming said pivot along the joint rotation axis. This pivot is fixed by radial teeth formed on the counter surfaces of the named plates. Along the rotation axis between the plates, there is a cylindrical compression spring. The pivot axes on the adjacent ends of the bars are perpendicular to the bar axes and the axis of the fixed pivot, and on the bars, between these pivots and the fixing arms, there are provided cylindrical compression springs.

EFFECT: invention provides improved therapeutic effect, reduction treatment time and operative injuries with better anatomic and functional clinical outcomes.
