## Abstract

A limb positioning system includes a clamp assembly, a pylon and bar assembly, a sled assembly, and a limb positioning assembly. The clamp assembly is configured to attach to a bed rail of a surgical table and to accept a pylon connected to a bar. The pylon may have a plurality of pylon bars that are secured by the clamp assembly. A base bar may extend from the pylon, and may be attachable to an extension bar to provide a longer track along which the sled assembly may slide. The sled assembly may be biased to be locked with respect to the base bar. The limb holding assembly may include a boot coupled to the sled via a connector near the heel. The connector may be tapered and insertable into a correspondingly tapered section of a ball that sits within the sled assembly, the ball being capable of polyaxial motion.

## Claims

### Claim 1

A limb positioning system comprising:
a clamp attachable to a patient support, the clamp having first and second channels;
a first support member including first and second pylons extending outwardly from an elongate rod, the first and second pylons being receivable in the first and second channels so that the first support member is slideable relative to the clamp along a first longitudinal axis;
a second support member coupled to the first support member so that the second support member is slideable relative to the first support member along a second longitudinal axis transverse to the first longitudinal axis; and
a limb holder coupled to the second support member,
wherein the clamp includes a first wheel adjacent the first channel, and a second wheel adjacent the second channel, the first pylon includes a plurality of first notches spaced apart from one another, each first notch configured to receive the first wheel, and the second pylon includes a plurality of second notches spaced apart from one another, each second notch configured to receive the second wheel.

### Claim 2 (depends on 1)

The limb positioning system of claim 1, wherein the limb holder is polyaxially and hingedly coupled to the second support member.

### Claim 3 (depends on 1)

The limb positioning system of claim 1, further comprising a mount polyaxially coupled to the second support member, wherein the limb holder is hingedly coupled to the mount.

### Claim 4 (depends on 3)

The limb positioning system of claim 3, wherein the limb holder is detachably coupled to the mount.

### Claim 5 (depends on 1)

The limb holder positioning system of claim 1, further comprising:
a height adjustment member coupled to a rear of the limb holder; and
a support wing adjustably coupled to the height adjustment member.
