Abstract

Claims (39)

1 . A reversible compressor-distractor comprising:

(a) a first engagement arm comprising:

(i) a first side pin-receiving hole for receiving a first pin inserted into a first bone portion, the first side pin-receiving hole extending from a first pin entry opening to a first pin exit opening; and

(ii) a second side pin-receiving hole for receiving the first pin inserted into the first bone portion, wherein the second side pin-receiving hole is on an opposite lengthwise side of the first engagement arm than the first side pin-receiving hole, and the second side pin-receiving hole extends from a second pin entry opening to a second pin exit opening;

(b) a second engagement arm comprising a pin-receiving hole for receiving a second pin inserted into a second bone portion; and

(c) an actuator operatively coupled to the first engagement arm and the second engagement arm, the actuator being configured to move the first engagement arm and the second engagement arm each other to move the first bone portion toward the second bone portion.

2 . The reversible compressor-distractor of claim 1 , wherein:

the first engagement arm has a length extending from a first end to a second end;

the first side pin-receiving hole extends through the first end of the first engagement arm; and

the second side pin-receiving hole extends through the second end of the first engagement arm.

3 . The reversible compressor-distractor of claim 2 , wherein:

the first engagement arm has a sidewall;

the first side pin-receiving hole extends from the first end of the first engagement arm through the sidewall at a first location; and

the second side pin-receiving hole extends from the second end of the first engagement arm through the sidewall at a second location.

4 . The reversible compressor-distractor of claim 3 , wherein the first location is offset along the length of the first engagement arm from the second location.

5 . The reversible compressor-distractor of claim 3 , wherein:

the first side pin-receiving hole defines the first pin entry opening at the first location of the sidewall and the first pin exit opening at the first end of the first engagement arm; and

the second side pin-receiving hole defines the second pin entry opening at the second location of the sidewall and the second pin exit opening at the second end of the first engagement arm.

6 . The reversible compressor-distractor of claim 2 , wherein a longitudinal axis defined by the first side pin-receiving hole intersects a longitudinal axis defined by the second side pin-receiving hole at a location between the first end and the second end of the first engagement arm.

7 . The reversible compressor-distractor of claim 1 , wherein the reversible compressor-distractor is configured to be flipped from a first orientation in which a first end is positioned closer to the first bone portion than a second end and the first pin is inserted through the first side pin-receiving hole to a second orientation in which the second end is positioned closer to the first bone portion than the first end and the first pin is inserted through the second side pin-receiving hole.

8 . The reversible compressor-distractor of claim 1 , wherein:

the second engagement arm has a length extending from a first end to a second end; and

the pin-receiving hole extends from the first end through the second end of the second engagement arm.

9 . The reversible compressor-distractor of claim 1 , wherein:

the first side pin-receiving hole defines a first longitudinal axis;

the second side pin-receiving hole defines a second longitudinal axis;

the pin-receiving hole of the second engagement arm defines a third longitudinal axis; and

the first longitudinal axis and the second longitudinal axis are each angled relative to the third longitudinal axis.

10 . The reversible compressor-distractor of claim 9 , wherein an angle between the first longitudinal axis and the third longitudinal axis is equal and opposite to an angle between the second longitudinal axis and the third longitudinal axis.

11 . The reversible compressor-distractor of claim 9 , wherein:

the first longitudinal axis is angled relative to the third longitudinal axis in one or both of a frontal plane and a sagittal plane; and

the second longitudinal axis is angled relative to the third longitudinal axis in one or both of the frontal plane and the sagittal plane.

12 . The reversible compressor-distractor of claim 11 , wherein the first longitudinal axis and the second longitudinal axis are each angled relative to the third longitudinal axis in the frontal plane at an angle ranging from 2 degrees to 20 degrees.

13 . The reversible compressor-distractor of claim 11 , wherein the first longitudinal axis and the second longitudinal axis are each angled relative to the third longitudinal axis in the sagittal plane at an angle ranging from 5 degrees to 12 degrees.

14 . The reversible compressor-distractor of claim 1 , wherein the actuator comprises a threaded shaft operatively connected to the first engagement arm and the second engagement arm and at least one unthreaded shaft extending parallel to the threaded shaft.

15 . The reversible compressor-distractor of claim 1 , further comprising a first bridging arm between the actuator and the first engagement arm and a second bridging arm between the actuator and the second engagement arm.

16 . The reversible compressor-distractor of claim 1 , further comprising a locking mechanism configured to lock a position of one or both of the first pin and the second pin, when inserted into the reversible compressor-distractor.

17 . The reversible compressor-distractor of claim 16 , wherein the locking mechanism comprise a locking arm operatively connected to a spring, and the locking arm has a contact end configured to press against one of the first pin or the second pin.

18 . The reversible compressor-distractor of claim 17 , wherein the locking arm is configured to apply an orthogonal moment to one of the first pin or the second pin.
