Configuration examples

Rekrea fixator body

Rekrea fixator body includes patient key and screw head covers

Insertion clamps on fixator body

To insert the clamps on the body remove the mobile end by loosening the locking screw. Insert the clamps by sliding along the rods to the desired position and according to the planning. 

The assembly of the Rekrea fixator provides that the rod of the body with the marking “SKIN” is positioned closer to the skin. Replace the mobile end and tighten the locking screw.

Use compression/distraction key

Marking onto the compression/distraction screws, both fixed and mobile ends, is useful to indicate to patient the direction to turn the compression/ distraction key.

Turning the compression/distraction screw from A to C, the clamp moves towards to 0 position of the graduated scale marked on the external rod. Turning from A to B, the clamp makes the opposite movement.

 

NOTE It is recommended to close with one headcover cap the distraction/compression key in order to avoid that the patient manages it and uses only the same end.

Rekrea bone screw clamps

All Rekrea bone screw clamps are made of aluminum alloy and are characterized by: 

Explanation of the clamp mechanism

 

Rekrea bone screw clamps

Standard clamp – SF26105

The standard clamp allows insertion of bone screws 

at any position along the axis of the fixator. On the lower side there are two screws, green and 

pink: the pink screw locks the sliding of the clamp on the fixator (the direction of rotation is indicated with 

“LOCK” and “UNLOCK”). 

The green screw allows the activation of clamp movement, which is then performed by turning the activation nut at the end of the fixator body

Swivelling clamp – SF26115 

In addition to the features of the standard clamp, allows gradual angular correction up to ± 16°. The base has a graduated scale to indicate the amount of the deformity correction.

 At the base of the clamp, the lateral screw controls the displacement in varus and valgus.

 

Translating clamp – SF26110 

Allows gradual translation of the screw clamp and attached bone segment across the fixator body axis. Controlled by the screw at the centre of the clamp base.

Correction central screw

T clamp – SF26155

Acts as a fixed clamp when attached to the end of the fixator body. Enables the positioning of bone screws in the metaphysis. 

The screws are inserted in a triangular pattern: the two upper screws are parallel, and can be orientated at an angle of ± 13°; the lower, central screw is angled 9° upwards. 

The activation nut for distraction/compression is not obstructed.

Ring kit – SF26210 (ø170 mm)

SF26220 (ø200 mm)

The kit includes:
– a ring clamp to attach the ring to the side of
the fixator;
– a ring of internal diameter 170 mm or
200 mm.

Bone screw holder – F4-5610
Wire holder – F4-5612

These two accessories are used as connection between the ring and the gripping elements to the bone: bone screws or Kirschner wires.

DynaRek
The DynaRek allows protected dynamisation of the newly formed callus, avoiding the risk of collapse, and promoting its maturation.
It is locked to a fixator rod with the silicone cushion against the clamp to be dynamised.
This can then be unlocked to allow protected cyclic loading of the new callus.

Sandwich
Used in combination with standard, swivelling and translating clamps allows to increase the distance between the bone screws, for greater stability.

Trock
Mounted on a proximal swivelling clamp, enables varus/valgus adjustment of the proximal femur.

Bone screws

The stainless steel bone screws are stepped, with a double diameter, and the thread is coated with hydroxyapatite. 

They are available in thread diameters of 4 and 6 mm with a 6 mm diameter shank. Pre-drilling is performed with a 3 mm diameter drill bit for the 4 mm and with a 4,8 mm drill bit for 6 mm screws. 

The bone screws insert smoothly, and forma bond with the bone over time. It is also possible to withdraw the screws a little of they penetrate too far. 

NOTE When pre-drilling, avoid over-insertion: the drill bits are stepped to match the bone screws. It is important that the wider diameter of the drill bit does not reach the second cortex. 

Kirschner wires 

Used for the transport of bone segments Kirschner wires are of diameter 1.8 mm, length 310 mm and 400 mm
