摘要： 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 (alphac) 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 by the support part (11) and is aligned along the femoral collum (5) at said predetermined cutting angle (alphac) 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 cutting level (Lc). The invention also relates to the use of the instrument for performing such resection.

摘要： PCT No. PCT/SE96/00490 Sec. 371 Date Jul. 9, 1996 Sec. 102(e) Date Jul. 9, 1996 PCT Filed Apr. 17, 1996 PCT Pub. No. WO96/36285 PCT Pub. Date Nov. 21, 1996The invention relates to a drill guide instrument and method for guiding a drill tool (24) when drilling a longitudinal bore (4) through the neck (collum femoris) (5) of a human femur (9), subsequent to resection of the head (caput) (8) of the collum (5) along a cutting plane (P). The instrument comprises a drill guide (20), which is provided with a base member (21) and arranged to guide the drill tool (24) along a drill axis (B-B) relative to the base member (21), said base member (21) being intended to be applied against a cut end surface (11) of the collum (5) defining the cutting plane (P) for obtaining a predetermined orientation of the drill axis (B-B) relative to the cutting plane (P). A positioning member (22) extending from the drill guide (20) is intended to be contacted with the periphery of the narrowest portion (13) of the collum (5) in at least two circumferentially-spaced contact positions (30), so as to locate the drill axis (B-B) at a minimum distance from the periphery of said narrowest portion (13) of the collum (5). The invention also relates to the use of the instrument for performing such drilling.
