HEADLESS COMPRESSION CANNULATED SCREW
Headless compression cannulated screw is designed for small bone fractures and osteotomies requiring low-profile fixation, with fully buried headless design to deliver controlled compression while minimizing soft tissue irritation.
关键特性
Headless (buried) design to eliminate hardware prominence and reduce soft tissue irritation
Cannulated system for accurate guide-wire–assisted percutaneous placement
Variable pitch thread design generating interfragmentary compression during insertion
Dual-thread or differential thread geometry for optimized compression force
Self-drilling and self-tapping options to simplify surgical steps
High-strength titanium or stainless steel construction for durability and biocompatibility
Low-profile fixation suitable for intra-articular and periarticular regions
适应症
Headless compression cannulated screws are commonly used for:
Intra-articular fractures requiring precise reduction (e.g., scaphoid, carpal bones)
Small bone fractures of the foot and ankle
Femoral head and neck fixation in selected cases
Osteochondral fractures and fragment fixation
Arthrodesis (joint fusion procedures)
Osteotomies requiring stable compression with minimal hardware prominence
临床优势
Provides strong interfragmentary compression for primary bone healing
Completely buried implant design reduces need for removal due to irritation
Enables minimally invasive percutaneous techniques
Maintains articular surface integrity and smooth joint motion
Reduces soft tissue irritation compared to conventional headed screws
Versatile use across small bones and complex anatomical regions
可选配置
Partially or fully threaded headless designs
Variable thread pitch for controlled compression
Multiple diameters (commonly 2.4 mm to 7.5 mm systems depending on platform)
Cannulated screw sets with different lengths and trajectories
Options for self-tapping and non-self-tapping variants
