The Cannulated Cancellous Screws 4.0mm Half Thread are precision orthopedic implants used for stable fixation of fractures involving cancellous (spongy) bone. These screws feature a cannulated hollow core, allowing insertion over a guide wire for accurate placement under fluoroscopic or imaging guidance.
The half-thread design enables interfragmentary compression by allowing the threaded portion to engage the far fragment while the smooth shaft glides through the near fragment. This creates controlled compression across the fracture site, helping maintain alignment and promoting faster bone healing.
These screws are commonly used in fixation of fractures involving small to medium cancellous bone regions such as the ankle, femoral head, tibial plateau, distal femur, and other periarticular areas requiring stable compression fixation.
The cannulated structure supports minimally invasive surgical techniques, reducing soft tissue trauma while improving placement accuracy and surgical efficiency.
Manufactured from premium surgical-grade stainless steel or titanium (depending on configuration), the screws provide excellent strength, corrosion resistance, and long-term biocompatibility. Precision-engineered threads ensure smooth insertion and strong bone engagement.
These implants are widely used in orthopedic trauma surgery and veterinary orthopedic procedures for fracture stabilization in both small and large animals.
The system is fully sterilizable and supplied in professional surgical packaging for safe handling and efficient operating room workflow.
