One method, among others, of calcaneus distraction of the present disclosure comprises placing one or more guide pins through an ankle; attaching one or more calcaneus distraction devices to the one or more guide pins; distracting the one or more guide pins using the one or more calcaneus distraction devices; and/or securing reduction of calcaneus fragments through fixation of a distractor fastener, wherein the fixation of the distractor fastener is facilitated by a drill targeting guide.
Claims15
A calcaneus distraction system comprising:
- a calcaneus distraction device having:
- a threaded distractor arm having an L-shape comprising a first elongated longitudinal body extending between a first end and a second end, and a second elongated longitudinal body extending between the second end and a third end, wherein the first elongated longitudinal body and the second elongated longitudinal body are connected at an approximately 90 degree angle to one another,
- the first end having at least a first ball socket and the second elongated longitudinal body having threads on at least two opposing surfaces of the second elongated longitudinal body, the third end being configured to removably couple with a sliding distractor arm;
- the sliding distractor arm having a third elongated longitudinal body extending between a fourth end and a fifth end, and a fourth elongated longitudinal body extending between the fifth end and a sliding end, wherein the third elongated longitudinal body and the fourth elongated longitudinal body are connected at an approximately 90 degree angle to one another,
- the fourth end having at least a second ball socket and the fourth elongated longitudinal body having a channel throughout its longitudinal axis configured to fit the third end of the threaded distractor arm, wherein the third end of the threaded distractor arm is removably coupled to the sliding distractor arm by a distractor nut that is configured to rotate along the threads of the threaded distractor arm to displace the sliding distractor arm along the longitudinal axis of the threaded distractor arm;
- and
- a plurality of spherical ball guides configured to rotate within the first or second ball sockets, the spherical ball guides having a through channel configured to fit a guide pin.
