Canulated interference screws are used in orthopaedics and trauma surgery to securely fix tendon and ligament grafts. Particularly in anterior cruciate ligament (ACL) reconstructions, they enable the graft to be firmly anchored within the bone canal. The screw secures the inserted tendon directly within the drill channel, thereby creating the conditions for secure healing and early weight-bearing.

Cannulated interference screw

A cannulated interference screw is used to securely fix tendon or ligament grafts within the bone, particularly in knee surgery – and its hollow design facilitates precise insertion.

The cannulated interference screw is primarily used in orthopaedics and trauma surgery, particularly in ligament reconstructions, e.g. in the knee.

The cannulated interference screw is used to fix grafts or tendons, usually within a bone canal.

Advantages of the cannulated interference screw
The cannulated design features a central hollow channel. This allows the screw to be positioned precisely using a guide wire. This makes implantation easier for the surgeon and increases safety during the procedure. [micromed.com]

High-quality titanium interference screws from MICROMED
MICROMED offers cannulated titanium interference screws in a range of diameters and lengths. The implant system ensures reliable graft fixation and meets the high standards of modern orthopaedic surgery. The precise manufacturing and cannulated design allow for easy handling and accurate placement during surgery.

Why cannulated interference screws?
The combination of stable graft fixation, precise guidance via a Kirschner wire and high biocompatibility makes the cannulated interference screw the preferred solution for many ligament reconstructions. This fixation principle has proven its worth for many years, particularly in cruciate ligament surgery.
Typical applications of the cannulated interference screw:
Cruciate ligament reconstruction (e.g. anterior cruciate ligament, ACL)
→ The inserted tendon is clamped in place within the bone drill hole using the interference screw.
Fixation of tendon grafts (e.g. patellar tendon, semitendinosus tendon)
Sometimes also used in other ligament reconstructions

What does ‘cannulated’ mean?
‘Cannulated’ means that the screw has a hollow channel running through its centre.
This allows it to be inserted precisely using a guide wire (Kirschner wire).
This increases the accuracy and safety of insertion.

Principle of operation:
The screw is screwed in between the graft and the bone.
This creates a compressive effect (interference) that securely fixes the graft in place until it heals.
