Abstract:
A cutting guide instrument for enabling high-precision resection of the head (caput femoris) of the neck of a human femur (collum femoris) at a predetermined cutting angle to the femoral shaft and on a predetermined cutting level with respect to the proximal end of the caput, said cutting guide comprising:a support part, comprising a fixture member intended to be fixed to the femur during said resection; a longitudinal guide carrier, having a longitudinal axis, which in use of the instrument is supported by the support part with the longitudinal axis extending along the femoral collum at a predetermined alignment angle to the femoral shaft; and a cutting guide, which in use of the instrument is supported by and can be positioned along the axis of the guide carrier at a cutting position corresponding to the predetermined cutting level, wherein the longitudinal guide carrier and the cutting guide are adapted such that when the cutting guide is supported by the longitudinal guide carrier at the cutting position, the cutting guide is oriented at the predetermined cutting angle to the femoral shaft, and wherein the cutting guide is pivotable in relation to the axis of the guide carrier.
