🛠️ Surgical Technique Overview

The surgical technique of cannulated headless compression screws follows a precise clinical protocol to ensure optimal fracture stabilization:

Incision and Exposure Make a small incision (1-3 cm) near the fracture site, avoiding nerves and blood vessels. Gently separate soft tissues to expose the fracture end.

Fracture Reduction Restore the fracture to its normal anatomical position through manual traction and rotation, monitored under C-arm fluoroscopy.

Guide Wire Insertion Insert the guide wire along the designed direction, perpendicular to the fracture plane, under fluoroscopic guidance.

Determination of Screw Length Measure accurately using dedicated tools over the guide wire. Select a screw 2-4 mm shorter than measured to ensure it is fully countersunk.

Drilling Use a cannulated drill bit with irrigation cooling. Monitor depth with an image intensifier to prevent tissue damage.

Screw Insertion & Fixation Mount the screw onto the compression sleeve and advance over the guide wire. Tighten until the head is flush with the bone and fracture is compressed.

Wound Closure Irrigate the wound with saline and suture in layers (deep tissues then skin). Apply dressing and immobilization if necessary.

🔍 Product Detailed Description

What is a Cannulated Headless Compression Screw (CHCS)?
It is a specialized orthopedic implant used primarily for scaphoid and long bone fracture fixation. The screw generates compression across the fracture site and is designed to be countersunk below the articular surface, reducing soft tissue irritation.

Key Features & Types

CHCS implants are developed to provide stable fixation while minimizing damage. They are available in various configurations:

Fully threaded and Partly threaded screws
Self-drilling and Self-tapping designs
Cannulated (hollow) center for precise guide wire placement

Main Advantages

Reduced Soft Tissue Damage: Headless design prevents protrusion.
High Stability: Superior compression across the fracture gap.
Minimally Invasive: Facilitates faster recovery and smaller incisions.
Better Range of Motion: Smaller footprint compared to traditional plates or headed screws.

Frequently Asked Questions

What materials are these screws made of?

Cannulated Headless Compression Screws are typically manufactured from high-grade Titanium Alloy or Stainless Steel to ensure biocompatibility and strength.

How long is the recovery period after surgery?

Recovery time depends on the fracture severity. Generally, rehabilitation begins a few weeks post-surgery, with significant improvement seen over several months.

Can the screws be removed later?

While designed for permanent fixation, they can be removed if they cause pain or complications, subject to a physician's clinical assessment.

What are the primary indications for use?

They are ideal for fractures of long bones (femur, tibia, humerus), spiral fractures, nonunions, and specifically scaphoid fractures in the wrist.

Are there any activity restrictions after the procedure?

Patients are usually advised to avoid weight-bearing on the affected limb for several weeks and should follow a structured physical therapy program.

What makes the "headless" design advantageous?

The headless design allows the screw to be buried within the bone, preventing irritation to tendons and ligaments that often occurs with traditional screw heads.
