About Single Lock Polyaxial Screw

The Single Lock Polyaxial Screw from Advin Health Care is engineered to provide stable and flexible fixation in external fixator assemblies. Its polyaxial feature allows adjustment at various angles, helping surgeons achieve optimal alignment and secure bone stabilization. The screw is durable, easy to handle, and compatible with standard external fixation systems. It enhances fracture management by offering reliable fixation, precision, and surgical convenience in trauma orthopedic procedures.

Advanced Features:

Polyaxial design for versatile angulation and positioning
Ensures stable fixation and precise bone alignment
Made from high-quality stainless steel for durability
Easy to handle and adjust during surgery
Compatible with standard external fixation systems

Superior Versatility and Compatibility

Designed to integrate seamlessly with standard polyaxial rod systems, this screw offers broad compatibility. Its carefully engineered polyaxial head enables multi-directional movement, accommodating spinal anatomy and varied surgical requirements. Whether for percutaneous or open approaches, surgeons can choose between cannulated or non-cannulated versions for tailored application.

Quality, Precision, and Safety

Each screw is manufactured to meet stringent international standards, including CE marking. The smooth, passivated surface finish, high corrosion resistance, and precise thread pitch (0.5 mm) minimize tissue trauma, enhancing patient outcomes. With unique lot and serial tracking, every implant ensures full traceability through the supply chain.

Streamlined Sterilization and Packaging

Pre-sterilization using gamma radiation assures safety, while individual blister packaging maintains a sterile barrier until use. Shelf life extends to five years when stored correctly, and clear storage guidelines ensure longevity. This single-use, lightweight, and portable screw is ideal for a range of clinical settings and meets the highest standards for medical devices.

FAQs of Single Lock Polyaxial Screw:

Q: How should the Single Lock Polyaxial Screw be sterilized before use?

A: The screw is pre-sterilized using gamma radiation and is delivered in an individually blister-packed and sealed package. No additional sterilization is required before use unless the packaging is compromised.

Q: What makes this screw compatible with existing spinal fixation systems?

A: It is designed to work seamlessly with standard polyaxial rod systems, ensuring compatibility with commonly used spinal fixation hardware for ease of integration during procedures.

Q: When should a cannulated versus a non-cannulated screw option be used?

A: Cannulated screws are ideal for minimally invasive, percutaneous insertion where guidewires assist accurate placement, while non-cannulated screws suit traditional open surgical approaches.

Q: Where can the screw be stored to maintain its shelf life and sterility?

A: Store the screw in a cool, dry, sterile environment as recommended, ensuring the blister packaging remains intact. This preserves sterility and prolongs shelf life up to five years.

Q: What is the process for inserting this screw during surgery?

A: The screw can be inserted using either a percutaneous or open surgical approach, with a self-tapping tip and threaded shaft for secure fixation. Surgeons should follow standard spinal fixation protocols for best outcomes.

Q: How does the screws design benefit both surgical teams and patients?

A: Features such as a secure locking mechanism, polyaxial head for multi-directional fixation, high radiopacity for imaging, and lightweight construction facilitate ease of use, accuracy, and patient safety during spinal surgery.

Q: What materials are used to manufacture the screw, and why are they chosen?

A: Made from medical grade titanium alloy (Ti-6Al-4V) or stainless steel, these materials are selected for their biocompatibility, strength, resistance to corrosion, and compatibility with medical imaging.
