Smart Correction Computer Assisted Hexapod Ring External Fixator System smart correction' Computer-Assisted Hexapod Ring External Fixator System

The basic system is comprised of two rings or partial rings, combined with six struts. The system is augmented by easy to use web-based software with Radiographic Navigation which provides a schedule detailing the necessary strut adjustments needed to achieve the chosen deformity correction. The Smart Correction® Computer-Assisted Circular Hexapod External Fixator System is a copyrighted software based, deformity correction and fracture reduction tool. This hexapod and ring external fixator, provides easy application, high mechanical stability and precise correction via web based software...

Advanced Wire and Screw Clamp a lightweight ring. The Smart Correction® System also allows surgeon to use 2/3 and foot rings. Full rings and 2/3 rings are available between 105mm and 300mm inner diameter with 15mm increase. Provide desired screw and wire position on the rings, through fully adjustable wire and screw height angles. Telescopic Strut Manufactured from Titanium and Aluminium offering lightweight frame composition. There are two strut option with Smart Correction, Universal Joint and VariJoint Struts. The Express Strut option provides the acute correction and fixes the adjusted...

Frame Assembly Positioning of the Proximal Ring The appropriate sized ring should be chosen to avoid ring contact with the skin both initially and during the correctional procedure. The rings have two concentric hole series. When constructing the fixator the outer holes must be used for the strut connections. Position the proximal ring, such that the fixation hole marked with no. 1 is placed as approximately Anterior to the bone as possible in the Sagittal plane. In general the ring is placed perpendicular (at 90°) to the long axis of the bone (in this example the proximal tibia), although...

Strut Attachment on the Distal Ring The struts are now fixed on the distal ring in pairs, in this case struts 2 & 3, struts 4 & 5 and struts 6 & 1. Ideally the pairs of struts should be attached at adjacent holes, however due to the advanced design of the Smart Correction® System the strut pairs can be separated by up to two or three ring holes. Similarly, the ideal position of the strut pairs is equidistant around the distal ring also. On a standard 39 hole example ring (165mm) this would be position no.7 & no.8 for strut 2 & 3, position no.20 & no.21 with struts 4 & 5 and finally position...

Recording Ring and Strut Size Software Instructions There are nine different ring diameters available ranging from 105mm to 225mm, and six strut lengths (XXShort, XShort, Short, Medium, Long and X Long). Each pair of holes in the ring is numbered, in order for the system to be able to provide a precise deformity correction protocol. The position and size of each strut and the size of the rings needs to be recorded. Any combination of ring and strut size may be used relevant to the deformity and patient requirements.

Data Entry Ring and Strut Selection Select the Ring and Strut tab, and select the corresponding ring and strut sizes as recorded in the Patient Data Form. Strut Position and Length Data Entry Select the Frame and Length tab. Enter each strut fixation hole number for both of the proximal and distal ring and each strut length as recorded on the Patient Data Form. Model Creation After the strut lengths and strut hole numbers have been entered the software then creates a frame model and shows both a Frontal and Lateral view. Smart tatav! X-Ray parameters Select the X-Ray parameters tab. Enter...

X-Ray image uploading and overlaying the template Bone Segments Mapping The surgeon is now required to locate the proximal and distal axis of each bone segment on both the Frontal and Lateral Views. After software generates the gridlined template, the patient radiographs will need to be uploaded to the software. Select the appropriate image file by clicking on “Browse” and choosing the image file corresponding to the A/P view. JPEG, PNG, BMP formats are acceptable. NOTE: the screen may darken slighly as the data is transmitted. Once the screen brightens again the orientation of the...

NOTE: The software will programme the frame adjustment schedule to bring the two fragment sections together through compression/distraction with concomittant discomfort and pain. The amount of compression/distraction can be determined and controlled by the positioning of these segments. At this point the amount of desired lengthening or compression (mm) and rotation (degrees) will need to be entered. When the deformity correction is completed, the distal bone segment (ring) will be rotated axially with respect to the proximal segment as viewed from above from the patient’s eyes. Note: This...

Deformity Correction Schedule Strut Replacement Select the “Correction Tab”. Enter the starting date for Callus distraction and the total correction period. The software will then generate the strut length adjustment schedule and an animation will start to show the fixator motion during the correction period in days. Bone segments movement per day will be written under the schedule table. During the course of treatment struts may need to be changed to accommodate changes in ring distances. This is indicated within the correction schedule. Where longer struts are required, they are...
