Cortical Bone Screw 4.5mm Hex Head for Veterinary TPLO Plate Fixation

Cortical Bone Screw 4.5mm is a stainless steel veterinary orthopedic screw designed for cortical bone purchase, plate fixation, TPLO support, fracture stabilization, and orthopedic implant constructs in veterinary surgery. The available variants are Cortical Bone Screw 4.5mm Length 12mm Hex Head, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm to 50mm, 52mm, 56mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 100mm, and 110mm Hex Head. The screw has a 4.5mm diameter, cortical thread profile, pointed tip, and hex head for controlled driver engagement during insertion. It is used with compatible veterinary orthopedic plates in TPLO procedures, long bone fracture repair, compression plate fixation, neutralization plating, corrective osteotomy, and trauma stabilization. Veterinary orthopedic surgeons, referral hospitals, large animal surgical teams, small animal practitioners, teaching institutions, and procurement teams use this screw range in orthopedic implant trays where larger diameter cortical fixation is required.

4.5mm Cortical Thread, Pointed Tip, and Hex Head Control

The 4.5mm cortical screw profile is selected when the operative plan requires a larger diameter screw for dense cortical bone purchase and plate fixation. The cortical thread pattern is intended to engage prepared cortical bone rather than cancellous metaphyseal bone, supporting stable fixation through compatible plate holes or directly across planned bone corridors. The pointed tip helps the screw enter the prepared track after drilling and depth measurement. The hex head allows engagement with a compatible hex screwdriver, giving the surgeon controlled insertion, alignment, and final seating. Correct driver fit is important because incomplete engagement can damage the head or reduce torque control. During placement, the surgeon maintains axial alignment, advances the screw gradually, monitors resistance, and seats the head according to the plate or fixation plan. Length selection should match measured bone depth, plate thickness, screw trajectory, and desired purchase.

TPLO Plate Fixation, Fracture Repair, and Cortical Bone Purchase

Clinical use begins after radiographic planning, patient positioning, surgical approach, reduction or osteotomy positioning, plate selection, drilling, and depth measurement. In TPLO procedures, Cortical Bone Screw 4.5mm may be selected for compatible plate holes where cortical fixation is required around the tibial construct. In fracture repair, the screw can secure compression plates, neutralization plates, bridging constructs, and selected long bone fixation systems. It may also be used in corrective osteotomy support, trauma stabilization, and veterinary orthopedic cases where a larger cortical screw diameter is appropriate. The surgeon selects the correct screw length after measuring the prepared hole and confirming whether near cortex, far cortex, and plate thickness require a specific working length. Screw placement depends on bone quality, plate compatibility, screw trajectory, reduction stability, and the surgeon’s fixation strategy.

12mm to 110mm Length Selection for Orthopedic Implant Trays

The 12mm, 14mm, 16mm, 18mm, 20mm, and 22mm variants are selected for shorter cortical fixation requirements, thinner bone corridors, or plate positions where limited screw length is appropriate. The 24mm to 50mm option supports a broad mid-length working range for routine plate fixation and long bone orthopedic use. The 52mm, 56mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, and 90mm variants provide extended options for deeper bone corridors and larger patient anatomy. The 100mm and 110mm variants are selected only when measured depth and surgical planning support a very long cortical screw. Keeping the full range available helps the team respond to intraoperative depth measurements without changing screw diameter or head style. Selection should follow drill path, plate thickness, target cortex, patient size, and verification that the screw does not create unwanted protrusion.

Stainless Steel Implant Handling, Inspection, and Procurement Documentation

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, threads, tip, 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 Cortical Bone Screw 4.5mm variants with compatible compression plates, TPLO plates, locking plates, drill bits, taps where applicable, depth gauges, hex screwdrivers, screw racks, and implant storage systems. CE marking, ISO 13485 certification, and FDA compliance language support purchasing documentation for veterinary hospitals, distributors, teaching programs, and institutional buyers. The $9.90 price, OEM availability, carton-box packing, and return and replacement support help maintain orthopedic implant inventory.

How is Cortical Bone Screw 4.5mm used in veterinary TPLO procedures? Cortical Bone Screw 4.5mm is used when a compatible TPLO plate or orthopedic construct requires larger diameter cortical screw fixation. After drilling and depth measurement, the surgeon selects the appropriate length, engages the hex head with a compatible driver, and advances the screw through the plate hole into the prepared cortical bone path. The screw helps secure the plate according to the planned fixation strategy. Final use depends on plate compatibility, patient size, bone quality, screw trajectory, and surgeon judgment.

Which screw length should be selected? Screw length should be selected after intraoperative depth measurement and confirmation of plate thickness, bone diameter, and desired cortical purchase. Shorter lengths such as 12mm to 22mm are used for smaller or shallower fixation points. Mid-length options from 24mm to 50mm cover many plate fixation requirements. Longer options from 52mm to 110mm are selected when the measured bone corridor requires greater working length. The surgeon should verify seating and avoid unwanted protrusion beyond the target cortex.

How does a cortical screw differ from a cancellous screw? A cortical screw has a thread profile intended for dense cortical bone purchase, while a cancellous screw has a deeper thread pattern intended for softer cancellous bone. Cortical Bone Screw 4.5mm is selected for plate fixation and cortical engagement in compatible veterinary orthopedic constructs. Cancellous screws are selected when the fixation point is primarily cancellous or metaphyseal bone. The choice depends on bone region, plate design, drilling technique, and the fixation objective.

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. A correct driver fit helps reduce slipping, head damage, and incomplete insertion control. During placement, the surgeon should maintain alignment, advance the screw gradually, and stop when the head seats properly against the plate or bone surface according to the operative plan.

What role does this screw serve in an orthopedic implant inventory? Cortical Bone Screw 4.5mm provides a larger diameter cortical fixation option for TPLO plates, compression plates, long bone fracture repair, neutralization constructs, and corrective osteotomy cases. It is stored with compatible plates, drill bits, taps where applicable, depth gauges, screwdrivers, screw racks, reduction forceps, and implant trays. Stocking the 12mm to 110mm length range helps the surgical team match screw length to measured bone depth during orthopedic procedures.
