Abstract
A surgical guide includes a body having four sides. The body comprises a first base at the first side, a second base at the second side and an elongated extension between the first and second base. The first base defines at least one first hole and the second base defines at least a second hole. The body is sized and configured to be installed above a joint line of a calcaneus and a talus bone and approximately mid-way along a longitudinal axis of a tibia. The first base is configured to receive at least one dowel of a second surgical guide in the at least one first hole and the second base is configured to receive at least one pin sleeve and pin in the second hole. Systems and methods are also disclosed.

A method, comprising:
- inserting a first guide above a joint line of a calcaneus and a talus bone;
- connecting a second guide to the first guide, the second guide having a first portion extending longitudinally in a first direction and a second portion extending laterally from the first portion in a second direction, wherein the first portion defines a first channel that runs the length of first portion on a first side and defines a second channel on a second side, which is disposed opposite the first side, and the second portion of the second guide defines a guide hole which is configured to engage a shaft of the first guide;
- connecting a portion of the second guide to a third guide, the third guide including a body having a first side, a second side, a third side, and a fourth side, the third and fourth sides extending between the first and second sides, wherein the body comprises a first base at said first side, a second base at said second side and an elongated extension between the first and second base, wherein the first base defines at least one first hole and the second base defines at least a second hole, and wherein the body is sized and configured to be installed above a joint line of a calcaneus and a talus bone and approximately mid-way along the longitudinal axis of a tibia;
- locking the location of the second guide and third guide about an axis defined by a shaft of the tibia using an adjustment mechanism attached to the third guide;
- coupling a fourth guide to the third guide, the fourth guide including first and second arms that are coupled together by a transverse beam and each of the first and second arms of the fourth guide define at least one of a hole or a slot for receiving an elongate radiopaque device therein;
- coupling an elongate radiopaque device to the fourth guide through the at least one hole or slot of the fourth guide;
- determining the alignment of the fourth guide and elongate radiopaque device using fluoroscopy;
- inserting at least one pin sleeve and pin into the second hole of the third guide;
- removing the fourth guide and elongate radiopaque device;
- inserting pins into the at least one first hole of the third guide and through two cortices of the tibia;
- and
- removing the first, second and third guides.

- wherein the third guide includes a body having a first side, a second side, a third side, and a fourth side, the third and fourth sides extending between the first and second sides, wherein the body comprises a first base at said first side, a second base at said second side and an elongated extension between the first and second base, wherein the first base defines at least one first hole and the second base defines at least a second hole, and wherein the body is sized and configured to be installed above a joint line of a calcaneus and a talus bone and approximately mid-way along the longitudinal axis of a tibia;
- inserting at least one pin sleeve into the second hole of the third guide;
- coupling a fourth guide to the third guide, the fourth guide including first and second arms that are coupled together by a transverse beam and each of the first and second arms of the fourth guide define at least one of a hole or a slot for receiving an elongate radiopaque device therein;
- coupling an elongate radiopaque device to the fourth guide through the at least one hole or slot of the fourth guide;
- connecting the second guide to the first guide;
- locking the location of the second guide and third guide about an axis defined by a shaft of the tibia using an adjustment mechanism attached to the third guide;
- determining the alignment of the fourth guide and elongate radiopaque device using fluoroscopy;
- inserting at least one pin into the pin sleeve that is inserted into the second hole of the third guide;
- removing the fourth guide and elongate radiopaque device;
- inserting pins into the at least one first hole of the third guide and through two cortices of the tibia;
- and
- removing the first, second and third guides.
11 more elements
A surgical guide system comprising:
- (a) a medial gutter fork including a shaft having proximal and distal ends and a head disposed at the distal end, the head configured for insertion into a medial gutter of an ankle joint to provide a rotational reference;
- (b) a rotation guide slide having
- (i) a first portion extending longitudinally and defining opposed first and second channels, each channel having a tapered cross-section configured to slidingly receive a complementary protrusion, and
- (ii) a second portion extending laterally from the first portion and defining a guide hole sized to receive the shaft of the medial gutter fork, the rotation guide slide being mountable on the shaft with either the first channel or the second channel oriented away from the tibia to accommodate right- and left-ankle procedures;
- (c) a flexion/extension guide including
- (i) a body sized to be positioned above a joint line of a calcaneus and a talus bone and approximately mid-way along a longitudinal axis of a tibia,
- (ii) a first base located at a distal end of the body and carrying a longitudinally extending protrusion dimensioned to be slidingly received in the first or second channel of the rotation guide slide,
- (iii) a second base located at a proximal end of the body and defining a channel that receives an engagement portion movable between superior and inferior positions, the engagement portion defining a pin hole,
- (iv) a first adjustment mechanism operative to lock the protrusion in the selected first or second channel, and
- (v) a second adjustment mechanism operative to fix the engagement portion at a selected position within the second base;
- (d) a removable pin sleeve sized to be received in the pin hole, the pin sleeve having opposed superior and inferior slots;
- and
- (e) a locking member carried by the engagement portion and selectively engageable with either of the superior or inferior slots to secure a pin inserted through the pin sleeve,
- wherein the rotation guide slide, flexion/extension guide, pin sleeve, and locking member cooperate to permit intra-operative adjustment and locking of both (i) mediolateral position about an axis defined by the shaft of the tibia and (ii) flexion or extension angle of a pin disposed in the pin sleeve while the medial gutter fork remains seated in the ankle joint.
