The Story
Synthes 3.5mm Cortex Screw | Self-Tapping | 75mm Length | 204.875
The Synthes 204.875 is a high-performance internal fixation implant designed for secure anchorage in dense cortical bone. As a 3.5mm diameter screw with an extra-long 75mm length, it is a specialized component of the Synthes Small Fragment System. This screw is engineered for "long-track" stabilization where standard small-fragment screws are insufficient, particularly in pelvic reconstruction, complex tibial plateau fractures, and calcaneal fixation.
The self-tapping distal tip features precision-machined cutting flutes that carve a matching thread path as the screw is advanced into a 2.5mm pilot hole. This eliminates the manual tapping step, which is critical when navigating a 75mm trajectory, as it maintains superior tactile feedback and reduces operative time.
Key Specifications
-
Manufacturer: Synthes (DePuy Synthes)
-
Model / REF: 204.875
-
Material: 316L Stainless Steel (Surgical Grade)
-
Screw Diameter: 3.5 mm
-
Thread Profile: Self-Tapping / Fully Threaded
-
Screw Length: 75 mm (Extended Reach)
-
Thread Pitch: 1.25 mm
-
Core Diameter: 2.4 mm
-
Head Type: 6.0 mm Head with Small Hexagonal Socket
-
Quantity: Individually Packaged, Sterile
Technical & Clinical Advantages
-
Extended Reach Stabilization: The 75mm length allows for bicortical fixation in wide anatomical planes, such as the ilium or across the calcaneus, where a standard 3.5mm screw would fall short.
-
Self-Tapping Efficiency: The integrated cutting flutes allow for direct insertion after the initial drill pass. This ensures the threads are perfectly matched to the bone's density, minimizing mechanical stress during deep insertion into the cortical mineral matrix.
-
High-Torque Hex Drive: The hexagonal recess is designed to transmit the significant torque required to seat a 75mm screw into dense bone without the risk of "cam-out" or stripping the screw head.
-
Universal Plate Compatibility: The 6.0mm spherical head is designed to sit flush within the non-locking portion of Synthes LCP (Locking Compression Plate) Combi-holes or standard 3.5mm DCP/LC-DCP holes.
-
316L Stainless Steel Biocompatibility: Cold-worked for high fatigue strength, the material is biologically inert and designed to withstand the cyclic loads encountered during the early stages of rehabilitation.
Applications
-
Pelvic & Acetabular Surgery: Stabilization of pelvic ring disruptions or acetabular fractures requiring long-track cortical anchorage.
-
Foot & Ankle Trauma: Fixation of complex calcaneal fractures or large-fragment pilon fractures.
-
Knee Trauma: Providing "rafting" support or interfragmentary compression in large tibial plateau fragments where 75mm of depth is required.
-
Non-union/Malunion Repairs: Utilizing extended lengths to bypass previous hardware tracks and achieve fresh cortical purchase.
Condition & Quality Assurance
-
Status: NEW — Factory Sealed & Sterile.
-
Integrity: This implant is securely packaged within its original manufacturer's sterile peel-pouch. The packaging is intact, ensuring the product's sterility, material integrity, and full lot traceability for clinical implantation in 2026.
-
Professional Standards: With over 25 years of experience in surgical hardware, Primis Medical ensures all Synthes implants are stored in climate-controlled environments to maintain the structural and sterile integrity of the hardware.
Shipping & Handling
-
Secure Logistics: Shipped in protective packaging to ensure the sterile barrier remains uncompromised and the 75mm shaft remains perfectly straight.
-
Fast Dispatch: Ships within 1 business day.
