Synthes 4.0mm Cancellous Bone Screw | Partially Threaded | 35mm Length | 207.035

The Synthes 207.035 is a precision-engineered internal fixation implant designed specifically for engagement in cancellous (spongy) bone. As a 4.0mm diameter screw with a 35mm length, it is a foundational component of the Synthes Small Fragment System. This screw features a partially threaded design, which is the mechanical requirement for creating a "lag effect" to achieve high-pressure compression across a fracture line in metaphyseal or epiphyseal bone.

Forged from implant-grade 316L Stainless Steel, the screw is non-absorbable and designed to provide high-tensile structural support during the biological stages of bone healing.

Technical & Clinical Advantages

• Mechanical Lag Effect: The partial threading ensures that the threads engage only the far (distal) bone fragment. Because the proximal shaft is smooth, the screw head draws the near cortex toward the far cortex as the screw is tightened, creating a powerful "vice-like" compression across the fracture gap.

• Cancellous Thread Geometry: The deep, widely spaced threads are specifically designed to "grip" the porous matrix of cancellous bone. This geometry maximizes surface area contact to prevent hardware pull-out in low-density bone environments.

• High Torque Hex Drive: The 2.5 mm hexagonal recess allows for the transmission of high insertion torque without the risk of "cam-out" or stripping the screw head, ensuring secure final seating even in dense metaphyseal bone.

• Low-Profile Spherical Head: The head is designed to sit flush within the counter-sunk holes of Synthes small fragment plates (e.g., 3.5mm LCP or DCP systems) or directly against the bone surface with a 7.0mm washer to prevent hardware subsidence.

• 316L Stainless Steel Biocompatibility: Cold-worked for high fatigue strength, the material is biologically inert and designed to withstand the cyclic loads of functional rehabilitation.

Applications

• Trauma Surgery: Stabilization of metaphyseal fractures in the distal radius, tibial plateau, or pilon.

• Malleolar Fixation: Ideal for medial malleolar fractures requiring significant interfragmentary compression.

• Pediatric Orthopedics: Fixation of epiphyseal injuries or triplane fractures where precision and compression are required.

• Plate Fixation: Serving as a "lag screw" through a 3.5mm LCP or DCP plate to achieve compression across an oblique fracture line.
