METHOD FOR FEMORAL CORTICOTOMY IN DISTAL ONE-THIRD Russian patent published in 2024 - IPC A61B17/56 A61B17/16 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for femoral corticotomy in a distal one-third. Consecutive counter perforation of cortical plates is performed along the planned fracture line. For this purpose, osteoperforations are drilled with drill bit or wire from two opposite sides of the femoral bone to the depth of the cortical layer. Osteotome equipped with a spike on the cutting edge is used for dissection of the cortical layer of the bone. Spike of the osteotome is placed in the perforated holes, and sections of the cortical plasty are sequentially dissected between the holes by striking the handle of the osteotome.

EFFECT: method enables femoral corticotomy in a distal one-third with a predictable fracture line while maintaining the integrity of the bone marrow and other structures of the medullary canal by using an osteotome with a spike, which sequentially dissects sections of cortical plasty between holes.
