Lateral positioner for elbow surgery

1. A lateral arm positioner apparatus for mounting on a rail of a table and for supporting a patient's arm when the patient is lying in a prone or lateral position on the table, the apparatus comprising:

a rail clamp having a clamp base securable to the rail and having a clamp body protruding upward from the clamp base;

a longitudinal socket defined in the clamp body;

an arm brace including a longitudinal post shaped to be received in the longitudinal socket of the clamp body; and

at least one lateral support arm extending from the longitudinal post positioned to support the patient's arm, wherein the at least one lateral support arm extends away from the rail clamp at an upward angle away from the rail clamp, wherein

the at least one lateral support arm includes a first lateral support arm and a second lateral support arm, and

the first and second lateral support arms define a brace recess between the first and second lateral support arms, the brace recess positioned to support a humeral region of the patient.

2. The apparatus of claim 1 , wherein the arm brace has an adjustable height relative to the rail clamp.

3. The apparatus of claim 2 , further comprising:

a socket disposed on the rail clamp; and

a socket fastener, wherein the socket fastener may be tightened and loosened relative to the rail clamp such that the socket fastener is tightened against the longitudinal post.

4. The apparatus of claim 3 , wherein:

the socket disposed on the rail clamp includes a transverse threaded bore extending from an exterior of the clamp body to the longitudinal socket; and

the socket fastener includes a threaded fastener inserted into the socket disposed on the rail clamp, wherein the socket fastener may be tightened against the longitudinal post.

5. The apparatus of claim 4 , wherein:

the longitudinal post includes a substantially flat surface; and

the threaded fastener selectably engages the substantially flat surface when tightened against to-the longitudinal post.

6. The apparatus of claim 1 , wherein the longitudinal post is selectively moveable relative to the rail clamp.

7. The apparatus of claim 6 , further comprising a removable foam pad positioned on the lateral support arm.

8. The apparatus of claim 6 , wherein the longitudinal post is selectively moveable relative to the clamp body of the rail clamp.

9. The apparatus of claim 1 , wherein the clamp base is offset from the clamp body.

10. The apparatus of claim 1 , wherein the at least one lateral support arm extends from a T-shaped junction of the longitudinal post.

11. A lateral arm positioner apparatus for mounting on a rail of a table and for supporting a patient's arm when the patient is lying in a prone or lateral position on the table, the apparatus comprising:

a rail clamp including

a clamp base securable to the rail,

a rail clamp fastener disposed on the clamp base, and

a clamp body protruding upward from the clamp base;

a longitudinal socket defined in the clamp body; and

an arm brace including

a longitudinal post shaped to be received in the longitudinal socket of the clamp body,

a T-shaped junction disposed at an end of the longitudinal post,

a first lateral support arm disposed on the T-shaped junction and extending away from the longitudinal post, and

a second lateral support arm disposed on the T-shaped junction and extending away from the longitudinal post,

wherein the first and second lateral support arms extend away from the rail clamp at an upward angle away from the rail clamp.

12. The apparatus of claim 11 , wherein the longitudinal post is selectively moveable relative to the rail clamp.

13. The apparatus of claim 11 , further comprising:

a first removable foam pad positioned on the first lateral support arm; and

a second removable foam pad positioned on the second lateral support arm.

14. The apparatus of claim 11 , wherein the first and second lateral support arms define a brace recess between the first and second lateral support arms positioned to support a humeral region of the patient.

15. The apparatus of claim 11 , further comprising:

a socket disposed on the rail clamp; and

a socket fastener, wherein the socket fastener may be tightened and loosened relative to the rail clamp such that the socket fastener is tightened against the longitudinal post.

16. The apparatus of claim 15 , wherein:

the socket disposed on the rail clamp includes a transverse threaded bore extending from an exterior of the clamp body to the longitudinal socket; and

the socket fastener includes a threaded fastener inserted into the socket disposed on the rail clamp, wherein the socket fastener may be tightened against the longitudinal post.

17. A method of supporting a supporting patient's arm when the patient is lying in a prone or lateral position on a table, comprising:

securing a clamp base of a rail clamp to a rail of the table, wherein a longitudinal socket is defined in a clamp body of the rail clamp;

inserting a longitudinal post into the longitudinal socket of the rail clamp, wherein the longitudinal post is defined on an arm brace having at least one lateral support arm; and

supporting the patient's arm on the at least one lateral support arm, wherein the at least one lateral support arm extends away from the rail clamp at an upward angle away from the rail clamp.

18. The method of claim 17 , further comprising moving the longitudinal post relative to the rail clamp.

19. The method of claim 18 , further comprising tightening a socket fastener relative to the rail clamp such that the socket fastener is tightened against the longitudinal post.
