Acumed developed Acutrak® screw technology to provide a headless compression-holding solution to fix fractures. It features the first fully threaded bone screw with a continuously variable thread pitch along the entire length of the screw.

What is Acutrak?

Acumed developed Acutrak® screw technology to provide a headless compression-holding solution to fix fractures. It features the first fully threaded bone screw with a continuously variable thread pitch along the entire length of the screw.

What are Acutrak screws made of?

The Acutrak 2 Standard headless compression screw has an hourglass shape and is composed of titanium alloy.

How does the arthrex FT compression screw provide compression?

at the tip of the screw enters the bone faster than each trailing thread, compressing the fragments progressively as the screw is advanced. and extra-articularly with minimal risk of impingement or soft-tissue irritation. insertion after drilling and facilitate efficient OR time.

What is compression screw?

Background. The Headless Compression Screw® (HCS) is a cannulated screw that is used for scaphoid fracture fixation. The screw generates compression across the fracture site prior to being countersunk below the articular surface.

What is headless screw?

Headless Compression Screws are designed to be used in bone reconstruction, osteotomy, arthrodesis, joint fusion, fracture repair and fracture fixation of bones appropriate for the size of the device. Headless Compression Screws are intended for bone fixation of the hand and foot flowing trauma or osteotomy.

What are cannulated screws?

Cannulated screws are a common method of fixation used by orthopedic surgeons for multiple fracture patterns. These screws may be cannulated or “hollow” to allow them to be placed over a guidewire facilitating better alignment prior to drilling or screw insertion.

Which headless compression screw produces the highest Interfragmentary compression force in scaphoid fracture?

Conclusion: Conical tapered screws and dual component screws produced statistically significant higher interfragmentary compression force at the scaphoid fracture site compared to shank screws.

What is the difference between locking and Nonlocking screws?

Locking screws make it impossible for screw insertion to alter the reduction. Nonlocking plate/screw systems require a precise adaptation of the plate to the underlying bone.

What do you call a bolt without a head?

A screw without a head is sometimes called a blind screw. Two types include dowel screws and set screws. Used for joining wood, dowel screws feature threads at both ends. Set screws are fully threaded and usually driven using an internal wrenching drive.

How do you unscrew a headless screw?

How to Remove a Screw With No Head

1. Use a center punch to put a deep hole right in the center of the screw shaft.
2. Start with a very small drill bit and drill a hole down into the shaft.
3. Turn the tool gently.
4. Remove the easy-out if the screw shaft is being stubborn and still won’t come out.

What is cannulated material?

Cannulated materials are commonly used in the manufacture of intramedullary rods and pedicle screws for the fixation of bone fractures or securing implanted products. This unique product can also be used for catheters and other instruments frequently used in the medical device industry.
