Premium 6.5mm Cancellous Screw

Our 6.5mm Cancellous Screw with 16mm Thread is a specialized, partially threaded orthopedic implant designed for precision large-fragment bone fixation. Featuring a short 16mm thread length, this screw is uniquely optimized for fractures where the far fragment is narrow or when maximum lag compression is required close to the bone’s articular surface.

The intentional 16mm partial thread configuration acts as an exceptionally efficient lag screw. By allowing the longer, smooth unthreaded shank to glide effortlessly through the near bone fragment, the deep threads anchor securely into the distal cortex or dense cancellous bone. This pulls the fracture fragments tightly together to create rigid interfragmentary compression. Equipped with a low-profile rounded head and a robust internal hexagonal drive socket, it ensures efficient torque transmission during insertion while minimizing post-operative soft-tissue irritation.

Key Features & Benefits

• Short 16mm Partial Thread Pattern: Specially designed to target smaller distal bone fragments, creating a powerful lag mechanism that pulls fracture lines tightly together for accelerated bone healing.

• Deep Cancellous Thread Profile: Features sharp, wide-pitch threads engineered to maximize surface area contact and provide excellent pull-out resistance inside porous or soft trabecular bone networks.

• High-Torque Hexagonal Drive: A deep, precision-machined internal hex socket eliminates driver slippage (cam-out), allowing for smooth, controlled surgical insertion.

• Low-Profile Domed Head: The rounded head sits flush against internal fixation plates or direct bone surfaces, mitigating patient discomfort and soft-tissue friction.

• Elite Biocompatibility: Fabricated from medical-grade Titanium Alloy or Stainless Steel to offer high fatigue resistance and eliminate adverse biological tissue reactions.

Clinical Indications

The 6.5mm Cancellous Screw (16mm Thread) is highly indicated for:

• Fixation of fractures in metaphyseal and epiphyseal areas with small distal fragments.

• Severe tibial plateau, calcaneal, and distal femoral fracture stabilization.

• Femoral neck fracture care and Slipped Capital Femoral Epiphysis (SCFE) fixation.

• Securing large fragment orthopedic compression plates to cancellous bone sections where a pronounced lag effect is needed close to the fracture line.
