Abstract
A femoral intramedullary rod system capable of treating a variety of femoral bone fractures using a uniform intramedullary rod design. The system generally comprising an intramedullary rod defining an opening having an upper surface and a transverse member including a bone engaging portion and a connection portion defining a thru-hole with the nail sized to pass therethrough. A pin is selectively coupled to the transverse member to rigidly assemble the transverse member to the nail when the nail is passed through the thru-hole and the pin is received within the opening. In an alternative design, an epiphyseal stabilizer is joined to the nail by a locking member.
Claims28
A reaming head, comprising:
- a body having a longitudinal axis and an outer surface defining a longitudinally extending substantially cylindrical configuration extending over a majority of the circumference of said outer surface and a truncated surface interrupting said substantially cylindrical configuration;
- a cutting element positioned in said truncated surface;
- a transverse axis, transverse to the longitudinal axis, the transverse axis intercepting at least a portion of the substantially cylindrical configuration, and intercepting at least a portion of the cutting element;
- wherein said cutting element is a blade spaced from said outer surface and extending in substantial alignment with said longitudinal axis.
A method of eccentric reaming, comprising:
- providing a reaming head having an outer surface with a cylindrical portion and a cutting element positioned opposite said cylindrical portion and configured for cutting upon oscillatory motion;
- inserting the reaming head into a bone opening;
- positioning said cylindrical portion adjacent tissue to be preserved;
- positioning the cutting surface adjacent tissue to be removed;
- oscillating the head of the reamer to cause the cutting surface to remove tissue.
A reaming head, comprising:
- a body having a longitudinal axis and an outer surface defining a longitudinally extending substantially cylindrical configuration extending over a majority of the circumference of said outer surface and a truncated surface interrupting said substantially cylindrical configuration;
- a cutting element positioned in said truncated surface and spaced from said outer surface;
- a transverse axis, transverse to the longitudinal axis, the transverse axis intercepting at least a portion of the substantially cylindrical configuration, and intercepting at least a portion of the cutting element;
- wherein said longitudinally extending substantially cylindrical configuration extends over an arc of at least 240° of the circumference of said outer surface.
A reaming head, comprising:
- a body having a longitudinal axis and a perpendicular axis perpendicular to the longitudinal axis;
- an outer surface disposed on a first side of the body,
- a truncated surface disposed on a second side of the body;
- a cutting element positioned in said truncated surface and spaced from said outer surface;
- a first end of the perpendicular axis intercepting at least a portion of the outer surface, and a second end of the perpendicular axis intercepting at least a portion of the truncated surface;
- wherein said cutting element comprises a blade extending in substantial alignment with said longitudinal axis.
A reaming head, comprising:
- a body having a longitudinal axis and a perpendicular axis perpendicular to the longitudinal axis;
- an outer surface disposed on a first side of the body,
- a truncated surface disposed on a second side of the body;
- a cutting element positioned in said truncated surface and spaced from said outer surface;
- a first end of the perpendicular axis intercepting at least a portion of the outer surface, and a second end of the perpendicular axis intercepting at least a portion of the truncated surface;
- wherein said outer surface extends over an arc of at least 240° of a circumference of said body.
