Anatomic femoral guide

摘要

An anatomic femoral guide positions bone tunnels corresponding to the AM and PL bundles in ACL repair and reconstruction procedures. A template guide disposed in a surgical field proximate to a surgical member such as a femur or tibia defines a surgical footprint of the resulting bone tunnel. The template includes apertures corresponding to the size of the bone tunnels for the respective (AM or PL) bundles, and allows positioning at the drilling site to identify the size and location of the bone tunnel, as well as the relative distance between tunnels for double bundle procedures. An offset angle in the template provides differing orientations of the template apertures for visualizing the actual bone tunnel placement. The template has an aperture positionable parallel to a tibial plateau formation on the tibia, and the template orients a second aperture angled by the offset angle for positioning the second tunnel.

主权项

1. A method of surgical drilling for attaching a supportive ligament structure, comprising:
disposing, in a surgical field, a surgical drilling guide including a housing having a sleeve disposed through an aperture for maintaining slideable communication with an insertion member, the insertion member being elongated and having an aimer tip and an insertion knob for disposing the insertion member slideably through the housing along an insertion axis; extending an aimer arm, the aimer arm engaging a slot in the housing for arcuate movement thereto, the aimer arm having a proximate end engaging the slot and an opposed distal end; disposing an aimer guide coupled to the distal end of the aimer arm, the aimer arm extending in an intersecting manner with the insertion axis; and positioning, adjacent to a surgical member for drilling, a template attached to the aimer guide, the template having a first aperture defining a drilling footprint on the surgical member, the drilling footprint located on the insertion axis and corresponding to a bone tunnel through which a surgical attachment is passed, wherein the template has a flattened construction providing a low profile, the flattened construction facilitating insertion between surgical members for disposing the template in parallel alignment with a surgical landmark for defining a location of the bone tunnel, wherein the template further comprises a second aperture corresponding to a second bone tunnel, the housing having a second sleeve for a second insertion member, an insertion angle being formed in the template, the insertion angle formed between the first and second apertures for defining locations of bone tunnels corresponding to the respective apertures, and wherein the aimer arm includes a director handle for manipulation by an operator, the director handle for positioning the insertion members on an opposed side of a surgical member from the template for drilling bone tunnels therethrough, the director handle including the aimer arm, an aimer arm extension slideably engaging the aimer arm for arcuate movement therein.
