EVOLOX® LOCKING SYSTEM
Plates with threaded locking holes manufactured at fixed angles are now widely used in orthopaedic surgery, with the beneits of these mono-axial locking plates being universally documented, and accepted.
The Evolox® System progresses this established technology to the next level through its unique and innovative design.
The surgeon now has freedom in the angular placement of the fixation screws, whilst still allowing three dimensional plate contouring to take place.
The design of the tapered twin start threaded locking hole allows the use of both conventional cortical screws (however these won’t lock into the plate), and compatible locking screws. Both screw types or any combination of the two can be positioned with up to 10° of angulation.
Unlike other angular locking systems available, there is no metal cutting involved in the locking of the screw head to the plate. This allows for easy removal or replacement.

REDUCED SOFT TISSUE IRRITATION
Low profile plates with rounded edges reduce soft tissue irritation, and aid wound closure.

VARIABLE ANGLE
Variable angle Screw holes allow up to 10° of directional angulation. (20° inclusive).

PULL OUT RESISTANCE
By opposing screws in varying angular directions using the Evolox® system the perpendicular pull out resistance is greatly increased. Combine this with a locked construct and the reduction of the fracture becomes a reliable fixation in osteoporotic bone. This would not be recommended for other systems with mono-axial.

SECURE FIXATION
The Evolox® technology creates a locked construct when used in conjunction with a compatible locking screw, providing angular stability, and a reduced risk of primary and secondary losses of reduction.

CRUMPLE ZONES
Plates in the Evolox® range that require anatomical bending are designed with crumple zones, that control the movement of the material during manipulation and direct distortion away from the locking holes. Locking plugs should be used for added protection.

PRESERVATION OF BLOOD SUPPLY
Locking plates do not need to be compressed against the bone to create a stable fixation, and thus reduces plate to bone contact, which in turn reduces complications caused by vascular trauma to periosteal tissue.

PLATE BENDING
The need to contour the plates to an accurate anatomical form prior to implantation is greatly reduced as the need to generate compressive forces between plate and bone isn’t required, the Evolox®  technology can be angled toward the fragment and still create a stable fixation. The reduced bending requirement also helps to retain the full strength of the plate.

SATIN FINISH
The non-relective surface gives less light glare during surgery and the uniform surface layer of compressive stress combats stress cracks and corrosion, which increases the implant life. The process itself leaves it free from residues with a low microorganism count.

MALLEABILITY
Evolox® is designed to be more malleable than competitor polyaxial plates and compression plates but its strength is closer to a compression plate than the leading polyaxial competitors – to request a study showing the strength comparisons of Evolox® Vs DCP’s Vs SOP, please contact us. It is important when using Evolox® that blank holes are filled with locking plugs both when contouring and when in situ in the patient as due to its malleability it is important to use plugs to maintain the plates overall strength.

Standard Evolox® plates are designed to be used where strength and maximum contourability/ malleability is needed. This plate malleabillity does mean its overall strength would be less than the equivalent compression plate so we would recommend if using on a long straight bone in dogs exceeding 30kgs where minimal contouring is needed and load bearing would be increased it may be better to consider the Evolox® PCL plates or the Evolox® 3.5mm broad plates. It is also recommended to use locking plugs to fill any empty holes as this will maintain the strength of the overall construct.

Maximum recommended torque for tapered screw head engagement:
3.5mm Locking screw = 2.30 N-mm (0.02 lbf-in)
2.7mm Locking screw = 1.15 N-mm (0.01 lbf-in)
Over tightening the screw may result in threads stripping, and loss of secure fixation.
In this event replace the over tightened screw with a conventional cortical screw.
Secure fixation can be achieved with much lower torque levels using locking screw technology.
