INITIAL F SiTa

.

The subtalar arthroereisis screws from the INITIAL F SiTa range are designed for the surgical treatment of hyperpronated feet.

Arthroereisis is a surgical procedure designed to limit subtalar eversion by inserting a wedge into the sinus tarsi. This helps realign the calcaneus into varus and restore talocalcaneal divergence.

The INITIAL F SiTa instrumentation kit includes all the instruments and templates intended exclusively for orthopedic surgery, specifically for the implantation or removal of Newclip Technics subtalar screws.

The screws are not included in the INITIAL F SiTa kit but are available separately in sterile single-unit packaging (S-box). Single-use kits offer numerous advantages, particularly in terms of traceability and safety, by reducing the risk of contamination⁽¹⁾ and bacterial biofilm formation⁽²⁾. They enhance surgical efficiency by lowering operative costs⁽³⁾ and perioperative time⁽⁴⁾ while improving workflow⁽⁴⁾. Their quick identification and intuitive use also facilitate the work of operating room teams.

Our sterile solution : INITIAL F SiTa.

INITIAL F SiTa KIT

INITIAL F SiTa consists of instrumentation for the insertion of subtalar arthroereisis screws to correct hyperpronated feet. This kit includes:

• 5 radiopaque plastic phantoms of different sizes. These phantoms correspond to the 5 sizes of subtalar arthroereisis screws provided separately. The phantom allows selection of the appropriate implant size according to the desired correction.
• Two Ø2.0 mm, 250 mm-long pins.
• A screwdriver composed of a handle and a cannulated threaded shaft. This assembly ensures secure locking by turning the shaft. Moreover, its cannulated design allows insertion of the shaft over the pin previously positioned in the tarsal canal.
• A dilator compatible with the screwdriver, used to enlarge the tarsal sinus canal before inserting the phantoms and the implant.

The screws are not included in the INITIAL F SiTa kit; they are available separately in sterile packaging (S-box).

INITIAL F SiTa SCREWS

Screw Specifications:

• Grade 5 titanium alloy screws
• Cannulated and guided by a pin
• Range of 5 implants from Ø8.0 mm to Ø12.0 mm (in 1 mm increments) corresponding to the phantoms included in the kit
• T40 hexalobe recess
• One-piece connection between the device and the screwdriver
