The invention relates to a cutting guide instrument and method for enabling high-precision resection of the head (caput femoris) (8) of the neck (5) of a human femur (collum femoris) at a predetermined cutting angle (.alpha.c) to the femoral shaft (9) and on a predetermined cutting level (Lc) with respect to the proximal end of the caput (8). A support part (11) is fixed to the femur during the resection. A longitudinal guide carrier (12) is supported b y the support part (11) and is aligned along the femoral collum (5) at said predetermined cutting angle (.alpha.c) to the femoral shaft (9). A cutting guide (13) is supported by and movable along the axis (D-D) of the guide carrier (12) to a cutting position corresponding to the predetermined cuttin g level (Lc). The invention also relates to the use of the instrument for performing such resection.
