Pro step Mica Screw system , what is it and what size options
The pro step MICA screw system is a cannulated fully threaded titanium screw system
Self tapping and headless
Diameters:
3mm Diameter: 20mm - 48mm (2mm increments)
4mm Diameter: 20mm - 60mm (2mm increments)

21. 4 mm screw, (blue, 20-60mm, 2mm increments, lateral / proximal
-2mm x 20mm Burr
Stab incision of the flare
Osteotomy with burr
Use elevator, first met translator
Drive wires into head, 1.4mm, 0.9mm
Measure for screw
Drill (cannulated)
Insert screws
Optional: remove sharp prominence with burr
Lapifuse
A Triplanar correction system to correct bunion
Joint prep kit, Triplanar clamp, lapifuse targeting guide, standard & trans-metatarsal titanium plates
2.5mm pins to hold clamp
1.4mm k-wire medial in center of metatarsal head
2 1.4mm k wires
Citrelock
Tendon fixation system
To avoid tendon lacerations
Resorbable screw for tendon fixation
Made of citregen (citrate molecule)
Prevents inflammation
Citrefix
Resorbable suture anchor system for soft tissue
Utilized in soft tissue reconstruction
Made of citregen
Variax 2 mini frag plate options
Profile, Narrow Locking, and Broad Locking plates
Profile locking plates
offered as straight plates only, ranging from 4 – 20-hole lengths.
Takes 2.0mm and 2.4mm screws
Broad Locking Plates
Variable angle locking, stronger option compared to narrow
Offered as straight plate only, 4-20 hole lengths
Takes all screw sizes
Narrow Plates
Variable angle locking, weaker option compared to Narrow locking.
Straight, T, Y, and triangle plate options
T-plates: 5 and 10-holes lengths
Y and Triangle plates: 10-hole options
Takes all screw sizes
Variax 2 mini frag plate specifics with screws
*Profile plates**
The circular holes in the light silver 2.0mm and 2.4mm - non-locking screws only.
Narrow and Broad Locking Plates
All circular holes in the dark grey 2.0mm, 2.4mm, and 2.7mm - both polyaxial locking and non-locking screw options
What are these
Screw/wire (4mm, 1.4mm) drill (3mm) driver (2.5mm) countersink (4mm)
Lapifuse: plates
Standard 5 hole - 0mm and 2mm step
Standard 6 hole - 0mm, 2mm step
Both available in right and left
2 locking holes for proximal fixation
2 locking holes for distal fixation
1 compression slot (2 in 6 hole plate)
Lapifuse: screws
Locking and non locking screws : 3.5mm
12mm - 40mm (2mm increments)
Interfragmentary (cross) screw : 4.0mm
35mm - 45mm (2.5mm increments)
Lapifuse steps
- Joint prep
Make incision over first Tmt joint, use distractor with (2) 2.5mm pins . Use joint prep kit - Fenestrate using 2.5mm drill and drill guide from prep kit
- Create incision over first mtp joint, insert (1) 1.4mm k wire
- Create incision in first interspace
- Insert clamp over to reduce IM angle
5.use targeting guide to place interfragmentary screw (4.0mm ) from base of first metatarsal, through medial cunueforminto body of intermediate cuneiform . Assemble targeting guide and insert two 1.4mm k wires - Place one kwire through targeting guide to temporarily secure the joints
- Measure: Remove targeting guide and replace with depth gauge to measure
- Pre Drill: 2.7mm drill and guide
- Insert screw ( 4.0mm) (35mm-45mm lengths) with driver
- Select plate: hold plate with temporary pins
- Measure using plate screw depth gauge
- Pre Drill: 2.5mm drill and guide
- Secure plate: with locking or non locking screws (3.5mm) (12mm-40mm lengths)
- (Optional) compression slot : pre drill : 2.5mm drill
- Measure for non locking screw (3.5mm) (12mm-40mm lengths)
- Insert screw: non locking screw into bone
- IF USING 6 HOLE PLATE:
INsert screw: locking or non locking screw through hole (3.5mm, 12-40mm lengths)
