HEADLESS COMPRESSION CANNULATED SCREW
无头加压空心钉适用于需要低切迹固定的小骨骼骨折及截骨术，无头设计使螺钉完全埋入骨面以下，提供可控加压同时最大限度减少软组织刺激。
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.
Cannulated system for accurate guide-wire–assisted percutaneous placement
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
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
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
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
