METHOD AND DEVICE FOR SURGICAL CORRECTION OF TRANSVERSALLY BROAD FOREFOOT Russian patent published in 2014 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: what is involved is a Z-osteotomy of diaphysis of a first instep bone with a middle cut plane of the Z-osteotomy lying along the axis of the first instep bone or approximately parallel with it. Two additional osteotomies are performed by making two additional cuts: additional cut is inclined to the upper cut so that an additional cut line on an upper surface of the first instep bone is at an angle of 5 to 30° to an upper cut line on the upper surface of the first instep bone; an additional cut is inclined to the lower cut so that the cut line on the lower surface of the first instep bone is at an angle of 5 to 30° to a lower cut line on the lower surface of the first instep bone; the formed bone fragments are removed; a sole fragment is displaced laterally and/or rotated in a horizontal surface; a medial or lateral angle of the sole fragment is integrated into an intramedullary canal of the instep bone; the sole and back fragments of the instep bone are fixed to each other using cannulated compression screws; a pre-dissected tendon of a great toe adductor is re-fixed to a first instep bone head using an anchor fixator for fixing the tendon to the bone.

EFFECT: prevented postoperative dislocation.
