Abstract

An intramedullary nail may include a shank with a centerline defined along a length thereof. The intramedullary nail may also include a channel with a channel axis transverse to the centerline. The channel may have an obround shape in a first cross-sectional plane perpendicular to the channel axis at the centerline and a tapered profile in a second cross-sectional plane containing the channel axis. A proximal edge of the channel within the second cross-sectional plane may form a first angle relative to the channel axis and a distal edge of the channel within the second cross-sectional plane may form a second angle relative to the channel axis that is different from the first angle.
