Synthes 440.16 Ti T-Plate 6 Holes 116mm

Synthes Ti T-Plate | 3-Hole Head / 3-Hole Shaft | 116mm | 440.16

The Synthes 440.16 is a high-strength internal fixation implant engineered for the stabilization of fractures at the metaphyseal-diaphyseal junction. As a 4.5mm system T-plate measuring 116mm in length, it is a foundational component of the Synthes 4.5mm Large Fragment System. The T-shaped configuration is specifically designed to provide a wide transverse "raft" of screws to support articular surfaces, while the longitudinal shaft provides stable anchorage to the bone diaphysis.

Constructed from implant-grade Titanium, the 440.16 offers an exceptional strength-to-weight ratio and a modulus of elasticity that more closely approximates human bone compared to stainless steel. This helps mitigate "stress shielding" and reduces the risk of hardware-related inflammatory responses in 2026.

Technical & Clinical Advantages

• Metaphyseal Buttressing: The transverse head of the T-plate allows for multiple screws to be placed parallel to a joint surface. This "buttress" effect is essential for preventing the collapse of articular fragments in fractures of the proximal tibia or distal femur.

• Dynamic Compression (DC) Capability: The shaft holes are designed with the standard Synthes DCP geometry. When screws are placed eccentrically, the plate facilitates horizontal movement to achieve active interfragmentary compression across the fracture line.

• Anatomical Contouring: While providing rigid fixation, the commercially pure titanium remains sufficiently malleable to be intraoperatively contoured with plate-bending irons to match the specific curvatures of the lateral tibia or pelvic brim.

• Titanium Biocompatibility: Titanium is non-ferromagnetic and highly corrosion-resistant. It produces significantly fewer artifacts on post-operative MRI and CT scans compared to stainless steel, allowing for clearer clinical assessment of joint alignment.

• High Core Rigidity: With a 4.5mm thickness, the 440.16 provides the structural stiffness required to withstand the high mechanical loads encountered during early protected weight-bearing.

Applications

• Tibial Fractures: Stabilization of proximal (medial or lateral) tibial plateau fractures.

• Distal Femur Trauma: Fixation of supracondylar fragments where a T-configuration provides optimal screw "rafting."

• Pelvic & Acetabular Surgery: Providing stable fixation for posterior column fractures or symphyseal disruptions.

• Humerus Fixation: Management of proximal humeral fractures in patients with larger bone morphology where 3.5mm hardware is insufficient.

Condition & Quality Assurance

• Status: NEW — Factory Sealed.

• Integrity: The implant is securely housed within its original manufacturer's packaging. Both inner and outer seals remain intact and undamaged, ensuring the product's structural integrity and suitability for clinical implantation.

• Sterilization Note: This device is provided in STERILE packaging. It is ready for immediate surgical use, provided the sterile barrier is uncompromised and the expiration date is verified per hospital protocol.

• Professional Standards: With over 25 years of experience in orthopedic logistics, Primis Medical ensures all titanium implants are stored in climate-controlled environments to preserve their chemical and mechanical properties.
