A limb positioning system (10) includes a clamp assembly (100), a pylon and bar assembly (200), a sled assembly (300), and a limb positioning assembly (400). The clamp assembly attaches to a rail (30) of a table and accepts a pylon (220) connected to a bar (240). The pylon has a plurality of pylon bars (222a, 222b) that are secured by the clamp assembly. A base bar (240) extends from the pylon, and is attachable to an extension bar (260) to provide a longer track for the sled assembly. The sled assembly is biased to be locked with respect to the base bar. The limb holding assembly includes a boot (402) coupled to the sled via a connector (460) near the heel. The connector is tapered and insertable into a correspondingly tapered section of a ball (380) that sits within the sled assembly, the ball being capable of polyaxial motion. |
