Cancellous Screws 4.0 mm Fully Threaded 35mm Length Hex Head are veterinary orthopedic bone screws designed for TPLO fixation, cancellous bone purchase, plate stabilization, and controlled fragment compression where a 4.0mm diameter screw with 35mm working length is selected. The fully threaded shaft provides thread engagement along the screw body, supporting fixation in metaphyseal and cancellous bone regions during veterinary orthopedic procedures. The hex head accepts a compatible hex screwdriver for controlled insertion, torque transfer, and final seating against the plate or bone surface. This screw pattern is used during tibial plateau leveling osteotomy support, cancellous bone fixation, periarticular stabilization, orthopedic plate application, and veterinary fracture management when the surgical plan requires a 35mm fully threaded cancellous screw. Veterinary orthopedic surgeons, referral hospitals, TPLO teams, large and small animal surgical units, distributors, and procurement teams use this item in orthopedic implant trays where size-specific screw selection and compatible instrumentation are required.
The Cancellous Screws 4.0mm pattern combines a 4.0mm screw diameter with a 35mm length for orthopedic situations where the surgeon requires a defined screw length and cancellous thread profile. The fully threaded body provides continuous thread purchase along the engaged bone path, making it useful when the fixation objective is stable thread contact rather than partially threaded lag compression. The hex head drive allows controlled insertion with a matching hex screwdriver, giving the operator tactile feedback during advancement, seating, and final tightening. In TPLO and plate fixation workflows, the screw is selected after measurement, drilling, tapping when required by technique, and confirmation of plate hole alignment. The head design seats against the selected plate or bone surface while the threads engage cancellous bone. This configuration supports predictable screw placement in planned orthopedic constructs where screw diameter, thread length, and driver compatibility must match the surgical system.
Clinical use begins after orthopedic planning, implant selection, exposure, osteotomy or fracture preparation, plate placement, and screw length measurement. During TPLO procedures, the 4.0mm fully threaded 35mm cancellous screw can be selected when the construct requires cancellous bone engagement and stable fixation through the planned plate hole. During periarticular orthopedic fixation, the cancellous thread profile supports purchase in metaphyseal bone, where bone density differs from cortical shaft bone. The hex head interface allows the surgeon to advance the screw through the plate and into the prepared track using a compatible driver. During final construct assembly, the screw contributes to plate-to-bone stability, fragment alignment, and load sharing according to the surgical plan. It is used with drill guides, depth gauges, taps, hex screwdrivers, orthopedic plates, forceps, retractors, and implant trays. Proper size selection follows preoperative measurement, intraoperative depth assessment, bone quality, plate type, and fixation objective.
This product is selected when the surgical plan specifies a 4.0mm fully threaded cancellous screw with 35mm length and hex head drive. The 35mm length should be matched to measured bone depth and plate position so the screw achieves the intended purchase without unnecessary protrusion. The hex head requires a compatible hex screwdriver tip that fits securely before insertion force is applied. During tray setup, the screw is placed with matched orthopedic instrumentation including drill bits, taps, depth gauges, screwdrivers, plate holders, reduction forceps, and TPLO plates. The fully threaded design differs from partially threaded cancellous screws because the threads run along the screw body rather than leaving a smooth shank for lag effect. This makes the screw appropriate when continuous thread engagement is required. Selection should align with implant system compatibility, plate hole geometry, bone quality, and the fixation pattern defined by the veterinary orthopedic procedure.
Surgical-grade stainless steel construction supports mechanical strength, corrosion resistance, and dimensional consistency for veterinary orthopedic implant use. Bone screws should be handled with implant forceps, compatible drivers, and clean tray technique to preserve thread geometry, head integrity, and surface condition before placement. The hex recess should remain undamaged so insertion torque transfers cleanly from the driver to the screw head. The screw should be inspected before use for thread damage, head deformation, surface defects, contamination, or packaging concerns. CE marking, ISO 13485 certification, and FDA compliance support procurement documentation for veterinary hospitals, orthopedic referral centers, distributors, and institutional buyers sourcing orthopedic implants and TPLO fixation components. The $2.20-$2.23 price range supports size-specific replenishment for implant inventory and screw rack planning. For purchasing teams, the product provides a defined 4.0mm fully threaded 35mm hex head cancellous screw for veterinary orthopedic fixation workflows.

What is the Cancellous Screws 4.0mm Fully Threaded 35mm Hex Head used for? This screw is used in veterinary orthopedic fixation where a 4.0mm fully threaded cancellous screw with 35mm length is required. It is commonly associated with TPLO procedures, cancellous bone purchase, plate stabilization, periarticular fixation, and veterinary fracture management when the fixation plan requires this diameter, length, and head type.
How does a fully threaded cancellous screw differ from a partially threaded screw? A fully threaded cancellous screw has threads along the screw body, supporting continuous engagement along the prepared bone path. A partially threaded screw has a smooth shank section and is often selected when lag effect is required. The fully threaded 35mm screw is selected when the surgeon wants thread purchase along the working length rather than a partially threaded compression pattern.
What driver is used with the hex head design? The hex head design requires a compatible hex screwdriver that fits the recess securely. Proper driver fit is important for controlled insertion, torque transfer, and final seating. A mismatched or worn driver can damage the hex recess and reduce insertion control during plate fixation or cancellous bone screw placement.
How is screw length selected during orthopedic fixation? Screw length is selected after preoperative planning and intraoperative measurement using compatible orthopedic measuring instruments. The 35mm length is chosen when it matches the measured bone depth, plate position, and fixation objective. Correct length selection supports intended purchase while avoiding unnecessary protrusion beyond the target bone surface.
How do CE, ISO 13485, and FDA compliance support procurement? CE marking, ISO 13485 certification, and FDA compliance support documented sourcing for veterinary orthopedic implants and fixation components. These credentials help veterinary hospitals, orthopedic referral centers, distributors, and procurement departments maintain purchasing records for TPLO screws, cancellous screws, plates, and related orthopedic implant systems.
