Cancellous Bone Screws 4mm (SKU: PS-VS-00643) are stainless steel veterinary orthopedic screws designed for TPLO fixation, cancellous bone purchase, plate stabilization, and controlled bone fixation where a 4.0mm fully threaded screw with 14mm length and hex head drive is required. The fully threaded shaft provides continuous thread engagement along the prepared bone path, supporting fixation in cancellous and metaphyseal bone during veterinary orthopedic procedures. The hex head accepts a compatible hex screwdriver for controlled insertion, torque transfer, and final seating against the selected plate or bone surface. This screw pattern is used during tibial plateau leveling osteotomy, cancellous bone fixation, periarticular stabilization, veterinary fracture management, orthopedic plate application, and implant inventory replenishment. Veterinary orthopedic surgeons, referral hospitals, TPLO teams, large and small animal surgical units, distributors, and procurement teams use this item where exact screw diameter, length, thread type, and driver compatibility must match the operative plan.
The Cancellous Bone Screws 4mm pattern combines a 4.0mm screw diameter with a 14mm working length for orthopedic fixation where short cancellous screw purchase is required. The fully threaded shaft provides thread contact along the screw body, making it suitable when the fixation objective is continuous engagement rather than a partially threaded lag effect. The cancellous thread profile is selected for metaphyseal and cancellous bone regions where thread geometry must support purchase in lower-density bone. The hex head drive allows the surgeon to insert the screw with a compatible hex screwdriver, giving controlled torque transfer during advancement and final seating. In TPLO and plate fixation workflows, the screw is selected after exposure, plate positioning, drilling, depth assessment, and confirmation of bone quality. The head seats against the plate or bone surface while the threads engage the prepared track. This configuration supports predictable placement in orthopedic constructs requiring a 4.0mm fully threaded 14mm hex head screw.
Clinical use begins after orthopedic planning, implant selection, tibial exposure, plate contouring, osteotomy preparation, and screw length measurement. During TPLO procedures, the 4.0mm fully threaded 14mm cancellous screw can be selected when the construct requires cancellous purchase through a planned plate hole and stable fixation in a short measured depth. During periarticular fixation, the cancellous thread profile supports purchase in metaphyseal regions where cortical screw geometry may not be the selected option. The hex head interface allows controlled advancement through the plate and into the prepared bone track using a matching driver. During final construct assembly, the screw contributes to plate-to-bone stability, fragment control, and load sharing according to the surgical plan. It is used with drill guides, depth gauges, taps, hex screwdrivers, orthopedic plates, reduction forceps, retractors, and TPLO implant trays. Correct selection follows bone depth, plate hole position, screw trajectory, and fixation objective.
This screw is selected when the surgical plan specifies a 4.0mm fully threaded cancellous screw with 14mm length and hex head drive. The 14mm length should match intraoperative depth measurement so the screw reaches the intended purchase without unnecessary protrusion beyond the target bone surface. The hex head requires a compatible screwdriver tip that seats securely in the recess before insertion force is applied. During tray setup, the screw is organized with matched orthopedic instrumentation including drill bits, taps, depth gauges, screwdrivers, plates, screw racks, and reduction instruments. The fully threaded design differs from partially threaded cancellous screws because the threads continue along the body instead of leaving a smooth shank for lag compression. This makes it appropriate when continuous thread engagement is required. Selection should align with the implant system, plate hole geometry, prepared track, bone quality, and veterinary orthopedic fixation plan.
Stainless steel construction supports mechanical strength, corrosion resistance, and dimensional consistency for veterinary orthopedic fixation. The screw should be handled with clean implant 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. Before use, the screw should be inspected 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 TPLO screws and cancellous fixation components. The $2.20 price point supports size-specific replenishment for screw racks, TPLO trays, and orthopedic implant inventory. For procurement teams, this product provides a defined 4.0mm fully threaded 14mm hex head cancellous screw for veterinary bone fixation workflows.

What is the Cancellous Bone Screws 4mm product used for? Cancellous Bone Screws 4mm are used in veterinary orthopedic fixation where a 4.0mm fully threaded cancellous screw is required. This 14mm hex head screw is commonly selected for TPLO fixation, cancellous bone purchase, plate stabilization, periarticular fixation, and veterinary fracture management when the fixation plan requires this diameter, length, and thread profile.
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 through 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 14mm screw is selected when the surgeon requires thread purchase along the working length rather than a partially threaded compression pattern.
What driver is required for the hex head design? The hex head design requires a compatible hex screwdriver that fits the recess securely. Proper driver fit supports controlled insertion, torque transfer, and final seating. A worn or mismatched driver can damage the hex recess and reduce insertion control during orthopedic plate fixation or cancellous screw placement.
How is the 14mm screw length selected during surgery? Screw length is selected after preoperative planning and intraoperative measurement using compatible orthopedic measuring instruments. The 14mm length is chosen when it matches 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 implant systems.
