Abstract

A method for positioning a patient on a surgical table for a surgical procedure on a hip of the patient includes removably mounting a table extender to the surgical table in an operating room by releasably attaching mounts of the table extender to side rails of the surgical table, wherein the mounts are configured to mount the table extender in only one orientation with respect to the surgical table; and positioning the patient on the surgical table such that shoulders of the patient are supported by the surgical table and hips of the patient are supported by the table extender, wherein the table extender has a rectangular shape so that the hips of the patient are positioned entirely on the table extender.

First claim

1 . (canceled)

2 . A method for positioning a patient on a surgical table for a surgical procedure on a hip of the patient comprising:
removably mounting a table extender to the surgical table in an operating room by releasably attaching mounts of the table extender to side rails of the surgical table, wherein the mounts are configured to mount the table extender in only one orientation with respect to the surgical table; and positioning the patient on the surgical table such that shoulders of the patient are supported by the surgical table and hips of the patient are supported by the table extender, wherein the table extender has a rectangular shape so that the hips of the patient are positioned entirely on the table extender.

3 . The method of claim 2 , wherein the table extender supports the patient from a point proximal to the hips.

4 . The method of claim 2 , wherein the table extender supports the patient to a point proximal to the knees.

5 . The method of claim 2 , comprising imaging at least one of the hips supported on the table extender using X-ray and/or CT imaging.

6 . The method of claim 5 , wherein the table extender comprises a base attached to the mounts, wherein the base is radiolucent such that the at least one of the hips is imaged without obstruction.

7 . The method of claim 6 , wherein there is no metal reinforcement extending across a width of the table extender or past the mounts in a length direction of the table extender so that that the at least one the hips is imaged without obstruction.

8 . The method of claim 2 , wherein positioning the patient on the surgical table such that the hips of the patient are supported by the table extender comprises placing a stabilizing pad between at least a portion of the patient and at least a portion the surgical table to reduce sliding of the patient relative to the surgical table.

9 . The method of claim 8 , wherein the stabilizing pad extends between the hips of the patient and the table extender.

10 . The method of claim 7 , comprising positioning the surgical table and table extender in a non-inclined position.

11 . The method of claim 10 , comprising tilting the surgical table and table extender so that the patient in a Trendelenburg position.

12 . The method of claim 11 , comprising tilting the surgical table and table extender to an angle indicated by an inclinometer of the table extender.

13 . The method of claim 8 , comprising securing the stabilizing pad to the side rails of the surgical table with straps of the stabilizing pad.

14 . The method of claim 2 , comprising applying a hip distraction force to the hip of the patient.

15 . The method of claim 14 , comprising applying the hip distraction force to the hip of the patient without using a perineal post.

16 . The method of claim 2 , wherein the only one orientation of the table extender is an orientation in which a top surface of the table extender is aligned with a top surface of the surgical table.

17 . The method of claim 2 , wherein the table extender comprises a rectangular base and a rectangular cushion attached to the rectangular base.

18 . The method of claim 17 , wherein the base comprises one or more openings for optional mounting of a perineal post and the cushion comprises at least one recess for accommodating the optional mounting of the perineal post.

19 . The method of claim 8 , wherein the table extender supports the hips so as to mitigate pelvic tilt.
