The 4 mm Cancellous Screws – Partial Thread & Full Thread – Titanium – 200 PCS is a professional orthopedic implant set engineered for fracture fixation, bone stabilization, and reconstructive orthopedic surgery. Featuring both partial thread and full thread configurations, this comprehensive screw assortment provides orthopedic surgeons with versatile fixation options for a wide range of clinical applications involving cancellous bone.

Cancellous screws are specifically designed with deep, widely spaced threads that maximize purchase in cancellous (spongy) bone. Their thread profile provides excellent fixation strength while supporting stable implant placement in areas such as the metaphysis and epiphysis of long bones. The 4 mm diameter offers an ideal balance between strength and precision for many orthopedic procedures.

The partial thread screws are designed to generate interfragmentary compression by engaging the far bone fragment while allowing the smooth shaft to glide through the near fragment. This compression technique helps stabilize fractures and promotes proper bone healing in selected clinical situations.

The full thread screws provide continuous thread engagement along the entire threaded length, making them suitable for maintaining fragment position where compression is not desired or where both bone fragments require secure fixation. Having both configurations available allows surgeons to select the most appropriate implant based on fracture type, bone quality, and surgical objectives.

Manufactured from medical-grade titanium, these orthopedic implants provide exceptional biocompatibility, high strength-to-weight ratio, and excellent corrosion resistance. Titanium is widely recognized for its durability and compatibility with modern orthopedic fixation systems, making it a preferred material for long-term implant performance.

This 200-piece implant set includes an assortment of partial thread and full thread screws in multiple lengths, allowing surgeons to address a variety of fracture patterns and anatomical requirements. The precision-machined threads ensure smooth insertion and dependable fixation when used with compatible orthopedic instrumentation.

The 4 mm Titanium Cancellous Screws are commonly used in foot and ankle surgery, hand surgery, wrist surgery, trauma surgery, sports medicine, osteotomy procedures, small bone fixation, and reconstructive orthopedic operations. They are suitable for use with appropriate orthopedic fixation systems according to accepted surgical techniques.

Designed for hospitals, orthopedic trauma centers, ambulatory surgical facilities, and specialty clinics, this implant assortment provides an organized inventory solution for modern orthopedic practices. Its premium titanium construction and precision engineering ensure consistent quality and dependable clinical performance.

FAQs

1. What are 4 mm Cancellous Screws used for?

They are used for internal fixation of fractures involving cancellous bone, providing stable fixation during orthopedic trauma and reconstructive procedures.

2. What is the difference between partial thread and full thread cancellous screws?

Partial thread screws are designed to create interfragmentary compression across fracture sites, while full thread screws provide uniform fixation along the entire threaded length without generating compression in the same manner.

3. What material are these screws made from?

These orthopedic implants are manufactured from medical-grade titanium, known for its excellent biocompatibility, corrosion resistance, and mechanical strength.

4. How many screws are included in the set?

This set contains 200 pieces of 4 mm cancellous screws, including both partial thread and full thread designs.

5. Are these screws reusable?

No. These are single-use orthopedic implants and should not be reused after implantation or resterilization.

6. Which surgical specialties commonly use these screws?

Orthopedic trauma surgeons, foot and ankle surgeons, hand surgeons, sports medicine specialists, and reconstructive orthopedic surgeons commonly use these implants.

7. Are these screws compatible with orthopedic fixation systems?

Yes. These screws are designed for use with compatible 4 mm orthopedic fixation systems and should be selected according to the manufacturer’s specifications and accepted surgical techniques.
