Method for determining the entry point of a femoral intramedullary rod and device for visualising the entry point

摘要

Method for determining the entry point of a femoral or tibial intramedullary rod, in which the distance between the anatomical axis and a first reference point, and that lying between the anatomical axis and a second reference point are measured, and according to the abovementioned measurements, a viewer is controlled, which viewer comprises a support plate (1) fitted in its lower part with an element including a first sliding surface for a first slide (4), a second sliding surface (13, 14) for a second slide (6) and means (8) for blocking the sliding of the two slides, the slides each comprising an element (4, 6) sliding parallel to the mid-plane (8) of the support plate (1), the said sliding element being fitted at one of its ends with a positioning feeler (5, 7), the support plate (1) comprising a vertical bore, thus constituting a piercing guide (12) corresponding to the entry point of a radiopaque reference rod, and the desired entry point is thus obtained, and implementation device.
