The 4mm Cannulated Cancellous Screws Partial Thread (14–90mm) are advanced orthopedic fixation implants designed for accurate, minimally invasive fracture fixation in cancellous (spongy) bone. These screws feature a cannulated (hollow) design, allowing insertion over a guide wire for highly precise placement and improved surgical control.
The partial thread design enables strong interfragmentary compression, making these screws ideal for fracture fixation where bone-to-bone compression is required for optimal healing. This improves stability, promotes faster bone union, and reduces the risk of implant loosening.
Manufactured from premium surgical-grade stainless steel or titanium (depending on configuration), the screws offer excellent strength, corrosion resistance, and biocompatibility. The precision-machined deep threads ensure secure grip in cancellous bone, providing reliable fixation under load-bearing conditions.
The 4mm size is widely used in small to medium bone procedures, including metaphyseal fractures, osteotomies, and reconstructive orthopedic surgeries in both human and veterinary applications. The wide length range (14–90mm) allows flexibility for different anatomical requirements and surgical techniques.
These screws are compatible with standard guide wire systems and orthopedic instrumentation, and are fully sterilizable for safe surgical use.
