Introduction

For the operativ treatment of the slipped femoral epiphysis K-wires or sliding screws are used to fix the epiphysis in situ. Usually these osteosynthesis are removed after the patient is adult and further growth is not expected. These patients often need second surgery, due to loosening of K-wires or if the head of the sliding screw is in contact with the lateral femur, thus stopping further growth potential of the growth plate.

With the new dynamic epiphyseal telescoping srew a device is now available, which allows the normal growth of the proximal epiphyseal growth plate and no changing of the osteosynthesis is necessary.

A stable fixation of the epiphysis against the metaphysis is guarantied.

Material and Methods

The dynamic epiphyseal telescoping srew is a device with two components. One has an self-cutting spongios thread which can be placed into the epiphysis. The growth plate is not fixed by the thread, which allows further growth. The end of this component is placed in the second component, a tube with a cortical thread at the end for the fixation in the lateral femoral cortical bone. Thus a slilding mechanism is available.

Results and Discussion

The surgical approach by using minimal invasive techniques is described. Furthermore the technical principles of the screw are demonstrated. The advantages of this new device are disccued in comparison with the fixation by K-wires or sliding screws aithout the telescoping apparatus.
