Surgical Technique

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

Fracture ReductionUse manual traction and rotation to restore anatomical position, monitoring continuously under C-arm fluoroscopy.

Guide Wire InsertionInsert the guide wire along the designed path under fluoroscopic guidance, perpendicular to the fracture plane.

Determination of Screw LengthMeasure using a dedicated device over the guide wire or by using an alternative wire comparison method. Select a screw 2-4 mm shorter than measured.

DrillingUse a cannulated drill bit of appropriate diameter. Drill along the guide wire while using irrigation solution to prevent thermal injury.

Screw Insertion & CompressionMount the screw onto the compression sleeve and advance over the guide wire. Turning the sleeve closes and compresses the fracture until the head is flush with the bone.

Wound ClosureIrrigate with normal saline, perform layered sutures for deep tissues and skin, then apply dressing and external fixation.

Product Description

What is a Cannulated Headless Compression Screw (CHCS)?

A CHCS is a hollow screw used in orthopedic surgery to fix bone fractures. Designed without a protruding head, it provides stable fixation while minimizing damage to surrounding soft tissues and articular surfaces. It is particularly effective for scaphoid fractures and long bone injuries.

Key Advantages:

Reduced Tissue Damage: Headless design prevents irritation to soft tissues.
Increased Stability: Provides superior compression compared to traditional screws.
Minimally Invasive: Enables faster healing and recovery through smaller incisions.
Hollow Center: Allows for precise guide wire placement and better irrigation.

Indications for Use:

CHCS are primarily used for fractures of long bones (femur, tibia, humerus), spiral fractures, nonunions, and malunions where compression across the fracture site is essential for healing.

Frequently Asked Questions

What materials are these screws made of?

These screws are typically manufactured from high-grade titanium alloy or stainless steel to ensure biocompatibility and strength.

How long does recovery take after surgery?

Recovery varies by fracture severity, but patients usually begin rehabilitation a few weeks post-surgery, with continued improvement over several months.

Can these screws be removed later?

Removal is possible if the hardware causes pain or complications, though many remain permanently if they are asymptomatic.

What are the main risks associated with this procedure?

Potential risks include hardware loosening, infection, or nerve/vascular damage, though these are minimized through proper surgical technique.

Are there activity restrictions post-surgery?

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

How is the correct screw length determined?

Surgeons use dedicated measuring devices over a guide wire or comparative wire techniques under fluoroscopic guidance to ensure precision.
