Cortex Bone Screw Self-Tapping 3.5mm is a stainless steel veterinary orthopedic screw designed for TPLO plate fixation, cortical bone purchase, fracture stabilization, and plate-screw fixation in veterinary orthopedic surgery. The available variants are Cortex Bone Screw Self-Tapping 3.5mm Length 10mm Hex Head, 12mm Hex Head, 14mm Hex Head, 16mm Hex Head, 18mm Hex Head, 20mm Hex Head, 22mm Hex Head, 24mm Hex Head, 26mm Hex Head, 28mm Hex Head, 30mm Hex Head, 32mm Hex Head, 34mm Hex Head, 36mm Hex Head, 38mm Hex Head, 40mm Hex Head, 42mm Hex Head, 44mm Hex Head, 45mm Hex Head, 46mm Hex Head, 48mm Hex Head, and 50mm Hex Head. The screw has a 3.5mm diameter, self-tapping cortical thread profile, pointed tip, and hex head for controlled driver engagement. It is used during TPLO procedures, compression plate fixation, neutralization plating, corrective osteotomy, long bone repair, and veterinary trauma stabilization.
The 3.5mm self-tapping cortex screw profile is selected when the operative plan requires mid-size cortical fixation with a screw tip designed to advance after pilot hole preparation. The cortical thread pattern engages prepared cortical bone through compatible veterinary orthopedic plate holes, while the self-tapping geometry can reduce a separate tapping step when the bone quality and implant protocol support that workflow. The pointed tip supports entry into the drilled path after depth measurement. The hex head allows engagement with a compatible screwdriver, giving the surgeon controlled torque transfer, axial alignment, and final seating against the plate or bone surface. Correct driver fit is essential because incomplete engagement can damage the hex recess and reduce insertion control. During placement, the surgeon advances the screw gradually, monitors resistance, confirms head seating, and checks the construct according to the fixation plan. The 3.5mm diameter provides stronger purchase than fine 1.5mm, 2.0mm, and 2.7mm systems while remaining smaller than 4.5mm cortical fixation.
Clinical use begins after radiographic planning, patient positioning, surgical exposure, osteotomy or fracture reduction, plate selection, drilling, and depth measurement. In TPLO procedures, Cortex Bone Screw Self-Tapping 3.5mm is selected for compatible plate holes where mid-size cortical purchase is required around the tibial construct. In fracture repair, the screw can support compression plates, neutralization plates, bridging constructs, and selected long bone stabilization systems. It may also be used in corrective osteotomy support, metaphyseal-adjacent fixation, periarticular stabilization, and veterinary orthopedic trauma workflows where a 3.5mm cortical screw diameter is appropriate. The surgeon selects the correct length after measuring the prepared track and confirming near cortex, far cortex, plate thickness, screw trajectory, and desired purchase. Proper placement depends on compatible drill bits, depth gauges, hex drivers, reduction forceps, plate holders, bone quality, reduction stability, and the selected veterinary implant system.
The 10mm, 12mm, 14mm, 16mm, 18mm, and 20mm variants are selected for shorter fixation points, smaller bone corridors, and plate positions where moderate screw length is required. The 22mm, 24mm, 26mm, and 28mm variants support deeper cortical purchase when measured bone depth requires additional working length. The 30mm, 32mm, 34mm, 36mm, 38mm, and 40mm options provide extended fixation choices for larger small-animal anatomy, broader bone corridors, and plate holes requiring longer engagement. The 42mm, 44mm, 45mm, 46mm, 48mm, and 50mm variants are selected for the deepest confirmed trajectories within this screw family. Keeping the complete range in an orthopedic inventory allows the surgical team to respond to intraoperative depth measurements without changing diameter or head style. Selection follows drill path, plate thickness, patient size, target cortex, far-cortex clearance, and final verification that the head seats properly against the plate.
Stainless steel construction supports thread integrity, head geometry, shaft strength, and handling during orthopedic tray preparation. Before use, the surgical team should inspect the screw head, self-tapping tip, threads, and shaft for visible damage, contamination, deformation, or packaging concerns. The hex recess should remain clean and clearly formed so the driver seats fully during insertion. Implant handling should follow facility protocol for sterile transfer, sterilization status, tray organization, documentation, and single-patient surgical use. Procurement teams can standardize Cortex Bone Screw Self-Tapping 3.5mm variants with compatible TPLO plates, compression plates, drill bits, depth gauges, hex screwdrivers, screw racks, and implant storage systems. CE marking, ISO 13485 certification, and FDA compliance support purchasing documentation for veterinary hospitals, distributors, teaching programs, and institutional buyers. The $2.20 price, OEM availability, carton-box packing, and return and replacement support help maintain orthopedic screw inventory for repeat case preparation.

How is Cortex Bone Screw Self-Tapping 3.5mm used in veterinary TPLO procedures?
Cortex Bone Screw Self-Tapping 3.5mm is used when a compatible TPLO plate or orthopedic construct requires mid-size cortical screw fixation. After drilling and depth measurement, the surgeon selects the correct length, engages the hex head with a compatible driver, and advances the screw through the plate hole into the prepared cortical bone path. The self-tapping thread supports insertion after pilot preparation when the operative protocol allows direct advancement. The screw helps secure the plate according to the fixation plan. Final use depends on plate compatibility, patient size, bone quality, screw trajectory, and surgeon judgment.
Which screw length should be selected from the 10mm to 50mm range?
Screw length should be selected after intraoperative depth measurement and confirmation of plate thickness, bone diameter, and intended cortical purchase. Shorter 10mm to 20mm options support moderate fixation points and smaller plate positions. The 22mm to 30mm options provide additional working length where measured bone depth requires it. Longer 32mm to 50mm lengths are selected for deeper bone corridors and larger patient anatomy. The surgeon should verify final seating and avoid unwanted protrusion beyond the planned cortex.
How does the self-tapping design differ from a standard cortex screw?
The self-tapping design includes tip geometry that can form threads during insertion after pilot hole preparation, depending on bone quality and surgical protocol. A standard cortex screw may require a separate tapping step when the system or bone density calls for it. Cortex Bone Screw Self-Tapping 3.5mm is selected when the surgeon wants a 3.5mm cortical screw option with self-tapping behavior for compatible TPLO and plate fixation workflows. The advantage is workflow efficiency while maintaining controlled driver engagement. Drill size, driver fit, and insertion alignment remain central to final screw performance.
What driver is required for this screw?
This screw uses a hex head and requires a compatible hex screwdriver from the appropriate veterinary orthopedic instrument system. The driver should seat fully before torque is applied. Correct driver fit helps reduce slipping, head damage, and incomplete insertion control. During placement, the surgeon maintains axial alignment, advances the screw gradually, monitors resistance, and stops when the head seats properly against the plate or bone surface. The hex recess should be inspected before use for clean geometry and undamaged engagement surfaces.
What role does this screw serve in an orthopedic implant inventory?
Cortex Bone Screw Self-Tapping 3.5mm provides a mid-size self-tapping cortical fixation option for TPLO plates, compression plates, long bone repair, corrective osteotomy, and veterinary trauma cases. It is stored with compatible plates, drill bits, depth gauges, hex screwdrivers, reduction forceps, screw racks, and implant trays. Stocking 10mm to 50mm lengths helps the surgical team match screw length to measured bone depth during orthopedic procedures. Procurement teams use this screw family to support predictable case preparation and replacement ordering.
