Abstract: A slotted cannula for surgical procedures is disclosed. The slotted cannula has an elongated semi-circular body comprising a cavity extending along a longitudinal axis of the semi-circular body, the cavity having an open distal end and an open proximate end and an integrally formed outward bend extending curvilinear from the cavity on the proximate end and at least one fold line across the width of the cannula, perpendicular to the longitudinal axis. The cannula can be bent or broken along the at least one fold line to adjust the operable length of the cannula during a surgical procedure.

Abstract: Embodiments are directed to an orthopedic fixation system that includes first and second plates each defining a clamp positioned at an end of the plate and comprising a first hole, a body portion extending from the clamp and comprising one or more holes, and one or more raised features positioned along the body portion. The clamp of the first plate is configured to couple with the body portion of the second plate. The first hole is configured to align with a second hole of the one or more holes. The first and second plates are rigidly coupled when an orthopedic screw engages with the first hole and the second hole and are coupled to a user.

Abstract: Embodiments are directed to an orthopedic nail that includes a shaft extending from a first end to a second end and defining one or more openings positioned proximate to the first end. Each opening can accept an orthopedic screw. The shaft can also define a first retention feature positioned proximate to the second end. The orthopedic nail can include a collar that couples to the shaft and defines one or more openings each configured to accept an orthopedic screw. The collar can define a second retention feature that engages with the first retention feature, where the first and second retention features allow the collar to be rotated with respect to the shaft and prevent the collar from decoupling from the shaft. The orthopedic nail can include a lock coupled to the collar and configured to engage with the shaft to prevent rotation of the collar with respect to the shaft.
