Abstract

Embodiments disclosed herein concern a distraction system for use with a surgical table having a table portion and a base portion. The distraction system includes a pair of arms rotatably connectable to the base portion at a proximal end portion of each arm. A pair of telescopically adjustable support posts extend upwardly from corresponding arms. Each arm rotates about a vertically oriented axis to provide for hip adduction and abduction of a patient's leg. Each support post extends from a linear bearing attacked to the corresponding one of the pair of arms for movement along the arm to facilitate applying traction to a patient's leg. The system can also include a table extension attachable to the table portion and a friction pad mounted on the table extension.

First claim

What is claimed is:

1 . A distraction system for use with a surgical table having a table portion and a pedestal foot, the distraction system comprising:
a base attachable to the pedestal foot; a pair of arms extending from the base and operative to support the legs of a patient; a table extension attachable to the table portion; and a friction pad mounted on the table extension.

2 . The distraction system of claim 1 , wherein each of the pair of arms is rotatably coupled to the base at a proximal end portion of the arm.

3 . The distraction system of claim 2 , wherein each arm rotates about an associated vertically oriented axis to provide for hip adduction and abduction of a patient's leg.

4 . The distraction system of claim 1 , further comprising an anchoring bracket configured to engage the pedestal foot and compress the base against the pedestal foot.

5 . The distraction system of claim 1 , further comprising a pair of support posts each extending upwardly from a corresponding one of the pair of arms.

6 . The distraction system of claim 5 , wherein each support post extends from a linear bearing attached to the corresponding one of the pair of arms for movement along said arm to facilitate applying traction to a patients leg.

7 . The distraction system of claim 1 , further comprising a caster and leveling foot assembly mounted to a distal end portion of each of the pair of arms.

8 . The distraction system of claim 1 , further comprising a perineal post extending upwardly from the table extension.

9 . A distraction system for use in surgical procedures, the system comprising:
a surgical table having a table portion and a table base portion; a pair of arms rotatably connected to the table base portion at a proximal end portion of each arm; and a support post extending upwardly from each of the pair of arms; wherein each arm rotates about an associated vertically oriented axis to provide for hip adduction and abduction of a patients leg.

10 . The distraction system of claim 9 , wherein each support post extends from a linear adjuster attached to the corresponding one of the pair of arms for movement along said arm to facilitate applying traction to a patients leg.

11 . The distraction system of claim 9 , further comprising a caster and leveling foot assembly mounted to a distal end portion of each of the pair of arms.

12 . The distraction system of claim 9 , wherein the table portion is adapted to tilt relative to the table base portion.

13 . The distraction system of claim 9 , wherein the pair of support posts are each telescopically adjustable.

14 . The distraction system of claim 9 , further comprising a friction pad mounted on the table portion.

15 . A distraction system for use with a surgical table having a table portion and a table base portion, the distraction system comprising:
a pair of arms connectable to the table base portion at a proximal end portion of each arm, wherein each arm independently rotates about an associated vertically oriented axis to provide for hip adduction and abduction of a patient's leg; a pair of linear adjusters each attached to a corresponding one of the pair of arms; a pair of telescopically adjustable support posts each extending upwardly from a corresponding one of the pair of linear adjusters.

16 . The distraction system of claim 15 , wherein the linear adjusters comprise linear bearings.

17 . The distraction system of claim 15 , further comprising a caster and leveling foot assembly mounted to a distal end portion of each of the pair of arms.

18 . The distraction system of claim 15 , further comprising a table extension attachable to the table portion.

19 . The distraction system of claim 18 , further comprising a perineal post extending upwardly from the table extension.

20 . The distraction system of claim 18 , further comprising a friction pad mounted on the table extension.

21 . A method for distracting a patient's hip joint, the method comprising:
applying a distraction force to the patient's leg; resisting the distraction force without the use of a perineal post, including:
tilting the patient backward on a support surface relative to the patients leg at an angle between 2 degrees and 20 degrees from horizontal; and
placing a friction increasing material between the patient and the support surface,

22 . The method of claim 21 , further comprising tilting the support surface to a contra-lateral side relative to the patient's leg at an angle between 0.5 and 2 degrees from horizontal.

23 . A method of configuring a surgical table as a distraction system, the method comprising:
attaching a distraction system base to a base portion of the surgical table; rotatably coupling a pair of arms to the distraction system base; attaching a table extension to a table portion of the surgical table; positioning a friction pad on the table extension; and tilting the table portion of the surgical table away from the distraction system base at an angle between 2 degrees and 20 degrees from horizontal,

24 . The method of claim 23 , wherein each arm rotates about an associated vertically oriented axis.

25 . The method of claim 23 , further comprising connecting an upwardly extending support post to each of the pair of arms.

26 . The method of claim 23 , further comprising tilting the table portion toward a latera; side of the surgical table at an angle between 0.5 and 2 degrees from horizontal.
