Cancellous Screw Short Thread

The Cancellous Screw Short Thread from Glass Agencies is an orthopedic fixation implant commonly used to achieve interfragmentary compression and stable fixation in cancellous bone during trauma and reconstructive procedures. This screw features a threaded section near the tip with an unthreaded proximal shaft, a configuration that supports effective compression across fracture lines when the head is tightened against bone or a plate. The short thread design allows the distal fragment to be securely engaged while the proximal fragment is drawn toward it, promoting firm contact between bone surfaces and encouraging primary bone healing. This type of screw is frequently used in metaphyseal regions and periarticular areas such as the proximal tibia, distal femur, ankle, and calcaneus, where cancellous bone structure provides suitable thread purchase. The thread profile is deep and widely spaced to support strong anchorage in spongy bone, helping resist pullout forces during functional loading. The smooth shaft reduces friction within the near cortex, allowing controlled sliding during tightening and supporting consistent compression across the fracture site. The screw head is contoured to seat accurately in compatible plate holes or directly against bone surfaces, supporting stable fixation without uneven stress concentration. The tip geometry assists with smooth advancement through predrilled holes, enabling predictable insertion and controlled progression during placement. The Cancellous Screw Short Thread is manufactured from medical grade stainless steel or titanium alloy, providing high mechanical strength, resistance to corrosion, and compatibility with the physiological environment of the human body. These materials support performance under cyclic loading and mechanical stresses encountered throughout the healing period. The surface finish is carefully controlled to support smooth interaction with bone and surgical instruments, helping manage insertion torque and reduce driver wear. The drive recess is compatible with standard orthopedic instrumentation, allowing secure torque transmission during insertion and removal. This screw is available in multiple diameters and lengths, allowing surgeons to select appropriate dimensions based on anatomical location, bone quality, and compression requirements. Glass Agencies maintains strict quality control throughout production, including checks for dimensional accuracy, thread consistency, surface quality, and structural integrity.
