cannulated compression screw

A cannulated compression screw represents a significant advancement in orthopedic fixation technology, designed to provide optimal stability and compression in bone fracture repair. This specialized surgical implant features a hollow central canal running through its length, allowing for precise placement over a guide wire. The design incorporates a threaded portion that engages with bone tissue and a smooth shaft that enables controlled compression across fracture sites. The screw's innovative architecture combines surgical grade stainless steel or titanium alloy with precision engineering to ensure maximum strength and biocompatibility. Its self-tapping threads enhance insertion efficiency while minimizing bone damage, and the variable thread pitch facilitates optimal compression. The cannulated design not only aids in accurate placement but also reduces the risk of surgical complications by allowing surgeons to verify positioning through radiographic imaging before final implantation. These screws come in various sizes and configurations to accommodate different anatomical requirements and fracture patterns, making them versatile tools in orthopedic surgery. Their application spans from small bone fixation in the foot and ankle to larger procedures involving hip fractures, particularly in the treatment of femoral neck fractures where precise placement is crucial for successful outcomes.

New Products

The cannulated compression screw offers numerous compelling advantages that make it an indispensable tool in modern orthopedic surgery. First, the hollow core design enables surgeons to achieve unprecedented accuracy in screw placement by using guide wires, significantly reducing the risk of misalignment and the need for revision surgery. This precision translates to shorter operating times and improved patient outcomes. The compression feature allows for controlled and adjustable pressure across fracture sites, promoting optimal bone healing conditions and faster recovery. Unlike solid screws, cannulated screws provide real-time confirmation of positioning through radiographic imaging, enhancing surgical confidence and reducing the likelihood of complications. The self-tapping design minimizes the need for pre-drilling, thereby preserving bone stock and reducing surgical trauma. The variety of available sizes and thread patterns makes these screws extremely versatile, suitable for both weight-bearing and non-weight-bearing applications. The biocompatible materials used in their construction ensure excellent tissue compatibility and reduce the risk of adverse reactions. The screws demonstrate remarkable stability in fixation, which is crucial for early mobilization and rehabilitation. Their design also facilitates easier removal if necessary, causing minimal tissue damage during extraction. The cost-effectiveness of these implants becomes apparent through reduced operating times, lower complication rates, and improved healing outcomes, making them a valuable investment for healthcare facilities.

Precision Guided Installation System

Precision Guided Installation System

The cannulated compression screw's precision guided installation system represents a revolutionary approach to orthopedic fixation. The hollow core design works in conjunction with guide wires to ensure unprecedented accuracy during placement. This system allows surgeons to first place a guide wire under radiographic guidance, confirming optimal positioning before committing to screw placement. The ability to verify placement before final implantation significantly reduces the risk of misalignment and potential damage to surrounding structures. This precision system also enables surgeons to make fine adjustments during the procedure, ensuring perfect alignment with the fracture site. The guided installation feature is particularly valuable in minimally invasive procedures, where direct visualization is limited.
Advanced Compression Technology

Advanced Compression Technology

The advanced compression technology integrated into these screws sets them apart from conventional fixation devices. The specially designed thread pattern creates controlled and uniform compression across fracture sites, which is essential for optimal bone healing. The variable pitch thread design allows for differential compression, where the leading threads engage the far cortex while the trailing threads compress the near cortex, creating ideal conditions for bone union. This compression can be precisely adjusted during surgery to achieve the perfect balance of stability and healing potential. The technology also incorporates a smooth shaft section that prevents thread interference while maintaining compression, ensuring consistent pressure distribution across the fracture site.
Versatile Application Capabilities

Versatile Application Capabilities

The versatile application capabilities of cannulated compression screws make them indispensable in modern orthopedic surgery. These screws are available in multiple sizes, thread patterns, and materials to accommodate various anatomical locations and fracture patterns. The design allows for effective use in both cancellous and cortical bone, making them suitable for everything from small bone procedures to major joint surgeries. Their versatility extends to different surgical approaches, whether traditional open procedures or minimally invasive techniques. The screws can be used independently or in combination with other fixation devices, providing flexibility in treatment planning. This adaptability makes them particularly valuable in complex cases where standard fixation methods may be inadequate.
