Design Rationale The CORETRAK® family of fixators is designed to simplify basic external fixation procedures. While most fixators use pin clamps that attach to the outside of a bar, the CORETRAK® design features clamps captured within a tube. This creates a smooth low profile device that is more patient friendly and easier for the surgeon to apply with no assembly required. At the heart of the CORETRAK® design is a unique internal screw-drive mechanism that provides compression or distraction capability. The system is designed with titanium nitride coated stainless steel pins to provide...

General Principles »» “Rule of Thirds” – The half pin diameter should not exceed 1/3 of the diameter of bone into which it is placed. »» Structures at Risk - Pin sites should be chosen carefully. Avoid areas containing neurovascular structures or tendons which may become impinged by the half pins. »» Bicortical Purchase - For optimum stability, half pins should be inserted through both cortices of the bone. Due to soft tissue risks, avoid over-insertion of the half pin. »» Minimum Two Pins Per Segement – For rotational stability, at least two pins should be inserted into each bone segment....

Basic CORETRAK® Application The first pin is placed perpendicular to the long axis of the bone. Use the fixator as a template to ensure proper alignment. | Figure 1 The pin diameter should not exceed 1/3 of the bone diameter. Align the fixator so that the distal internal pin clamp is positioned over the bone. | Figure 2A The internal clamp should be adjusted along the length of the fixator to position the pin holes in the desired location. | Figure 2B Insert the second pin through the fixator which is used as a guide. | Figure 3 Use fluoroscopy to check pin penetration through the far...

Insert the third and fourth pins through the fixator in the same manner as the first two pins. An AO adaptor can be used to connect to the pins to assist with the insertion. | Figure 4 A hole in the adaptor allows the screwdriver to manually advance the pins (inset). Proximal pins can be positioned in either a vertical or horizontal configuration depending upon the anatomy. Leave adequate clearance between the fixator and skin to allow for post-operative swelling. Lock the distal pins by tightening the set screws located within the fixator slot. | Figure 5 Lock the proximal pins by...

Articulating CORETRAK® Application 1st MPJ Arthrodiastasis A 1.6mm Kirschner wire is placed in the metatarsal head, through the approximate center of rotation of the 1st MPJ, from medial to lateral.1 | Figure 1 Radiographic images should be obtained to verify placement. | Figure 2 The cannulated hinge is then placed over the K-wire, making sure the M/L locking hex screw is away from the skin and the distraction segment of the fixator is distal. | Figure 3 Figure 4 | The most proximal half pin should then be inserted into the midshaft of the 1st metatarsal using the fixator as a guide. Avoid...

Insert the two remaining half pins. This photograph shows the manual or gradual insertion method for proper adjustment of half pin depth. | Figure 6 Figure 7 | The proximal half pins are locked using the hex driver 3.5mm. | Figure 7 The distal half pins are locked using the 2.0mm Allen wrench. | Figure 8 The proximal half pins are clamped with an internal Quad Lok™ mechanism. The image on the left shows the indicator pin in the unlocked position. | Figure 9 Clockwise rotation of the mechanism moves the indicator towards the locked position, clamping the half pins in place. | Figure 10 The...

Remove the K-wire. Adjust the medial/lateral alignment of the toe and lock down the dorsal/plantar hex screws. | Figure 11 Figure 12 | Adjust the toe for proper dorsal/plantar alignment and lock the medial/lateral hex screw. | Figure 12 Figure 13 | Document the current location of the Indicator on the graduated scale at the distal end of the movable half pin carriage. | Figure 13 Use the hex driver 3.5mm to distract the 1st MPJ per your protocol.2 | Figure 14 Once the patient has reached the distraction goal you may unlock the medial/lateral hex screw to allow for range of motion exercises....
