4.0mm Cancellous Screw for Metaphyseal Bone Fracture Fixation – Titanium and Stainless Steel Orthopedic Small Fragment Implants | OrthoPro

Premium 4.0mm Cancellous Screw for Orthopedic Small Fragment Fixation

The 4.0mm Cancellous Screw from OrthoPro is a specialized internal fixation device designed specifically for the treatment of fractures occurring in cancellous (spongy) bone. Unlike cortical bone, cancellous bone has a more porous structure, requiring a screw with a deeper thread and a larger pitch to achieve maximum purchase. Our 4.0mm cancellous screw is precision-engineered to meet these anatomical requirements, providing trauma surgeons with a reliable solution for stabilizing fractures in the epiphysis and metaphysis of long bones, as well as in the small bones of the hands and feet.

As a leading B2B supplier of orthopedic trauma implants, OrthoPro ensures that every 4.0mm cancellous screw is manufactured to the highest international standards. These screws are essential components in small fragment surgical sets and are widely used in hospitals and surgical centers globally to manage complex orthopedic injuries. The 4.0mm diameter is ideally suited for applications where a 3.5mm cortical screw may not provide sufficient grip in softer bone tissues.

Advanced Design and Material Specifications

The mechanical integrity of the 4.0mm Cancellous Screw is achieved through advanced manufacturing techniques and the use of premium medical-grade materials. To accommodate different clinical needs and surgeon preferences, we offer these screws in both Titanium Alloy (Ti6Al4V) and Stainless Steel (316L).

• Thread Design: The 4.0mm cancellous screw features a deep thread profile and a wide pitch, which increases the surface area in contact with the bone. This design is critical for preventing screw migration and ensuring long-term stability in osteoporotic or spongy bone.
• Head Profile: The screw is designed with a low-profile 6.0mm diameter head, which minimizes soft tissue irritation—a common concern in areas with minimal subcutaneous coverage, such as the ankle or wrist.
• Drive System: Equipped with a standard 2.5mm hexagonal socket, providing an excellent torque transmission interface that reduces the risk of head stripping during insertion or removal.
• Self-Tapping Capability: Most of our 4.0mm cancellous screws are self-tapping, allowing for easier insertion and reducing the need for pre-tapping, which saves valuable time in the operating room.

Technical Parameters and Configurations

To ensure total compatibility with existing orthopedic trauma systems, the 4.0mm Cancellous Screw is available in a variety of configurations. Surgeons can choose between full-thread and partial-thread options depending on whether they require static fixation or interfragmentary compression.

Clinical Applications and Indications

The 4.0mm Cancellous Screw is exceptionally versatile and serves as a primary fixation method for several orthopedic indications. Its ability to create “lag screw” compression makes it indispensable for articular fractures where anatomical reduction and rigid stability are mandatory. Key clinical applications include:

• Malleolar Fractures: Fixation of medial or lateral malleolus fractures in the ankle.
• Proximal Humerus Fractures: Stabilization of the humeral head in multi-part fractures.
• Tibial Plateau Fractures: Securing bone grafts or depressed articular fragments.
• Tarsal and Metatarsal Fixation: Used extensively in reconstructive foot and ankle surgery.
• Distal Radius Fractures: Providing support in complex wrist trauma.
