The DENS SYSTEM, consisting of fracture compression screws, associated instruments and the sieve basket bearing, is used to treat DENS fractures. The head thread has a smaller pitch than the thread at the tip. This geometry of the threads enables compression of the DENS fracture.

Information for patients

DENS fracture compression screws are fitted by an experienced orthopaedic surgeon or trauma surgeon. The procedure usually takes place in a specialised hospital under general anaesthesia. Before the implantation, a thorough diagnosis is carried out to ensure that the surgical technique and the implant are suitable for the patient. During the procedure, the screws are inserted directly into the bone and adjusted to compress the fracture. After implantation, the patient is monitored to make sure there are no complications. Healing can take several months, depending on the fracture and the patient’s health.

What is a fracture compression screw


Fracture compression screws are medical implants used to treat bone fractures. They are screwed fully into the bone and compress the fracture site to promote healing. These screws are made of a biocompatible titanium alloy.


Minimal invasive

The bone is accessed through a very small skin incision. The fracture compression screw cuts and drills its way into the bone by itself. This means that previously necessary surgical steps can be avoided and the operation requires less time and effort.

Facts about the fracture compression screw

How to use

Fracture compression screws are used especially where compression of the fracture is required and the implant must not protrude or bulge. The screw sinks completely into the bone so that it does not disturb the patient. This is particularly important in the area of the cervical spine.

Fields of application

Fracture compression screws are usually used for fractures or osteotomies in the spine, hand and foot.


The fracture compression screws are made of a biocompatible titanium alloy.


As with any surgical procedure, complications such as infection, swelling, pain and temporary limited mobility can occur.


Removal of metal

The fracture compression screw can be left in the body permanently or removed. It is up to the treating physician to decide whether the implant must be removed. In case of infection, implant fracture, loosening, secondary dislocation, recurrence of fracture, nerve or vascular irritation, implant removal is mandatory.
