Percutaneous fixation is an elegant method by which a necessary acampsia is made directly through the skin without large cuts. The method is unfortunately not suitable for every form of fixation. In particular it is difficult to make a reduction, i.e. a correction, such as those needed for spondylolisthesis. For the so-called post discectomie syndrome though, i.e. Micro-instabilities after disc surgery and fractures and inflammation, it is the method of choice. Screws are introduced into the vertebral body under the radiograph, only with puncture techniques. Then it can still be distracted, i.e. stretched and finally, the screws are connected with rods and secured with nuts.
The great advantage of this method is that no scars are being created, neither externally nor internally (i.e. in the muscle). Moreover, the operative time is short and the patient is immediately mobilised; he/she can get up directly after the procedure. Even the soreness is significantly lower than in the classical open surgery.
In addition to percutaneous fixation, there are also other forms of minimally invasive acampsia. The fundamental principle here is a gentle lateral transmuscular approach, in contrast to the classical midline incision. There are several "wire-guided" systems that are suitable for minimally invasive acampsia. Even a reduction and axial correction is possible with some, so that they can be used to correct spinal deformities.
