ABSTRACT:
A guide apparatus for orthopedic surgery provides locational guidance for insertion of an orthopedic nail through a pilot bore into the intramedullary canal of a fractured bone. The guide creates a protected channel through soft tissue which shields the soft tissue from contact by a reaming tool and prevents soft tissue from interfering with a reaming procedure. The guide collects marrow and bone fragments, removed during reaming to prevent their dispersion in soft tissue. Bone fragments and marrow collected on the guide are re-introduced into the canal for grafting. The apparatus includes an elongated chute having a concave, arcuate segment terminating at a spooned end adapted to be mounted controllably spaced in alignment with the pilot bore. An elongated pin secured to the backside of the chute extends beyond the spooned end of the chute for insertion into the proximate bone area. Both guide apparatus and method of utilizing the guide apparatus are disclosed.
