[A device for synthesis of the costal plane after posterolateral thoracotomy using transosseous incisions to prevent compression of intercostal nerves].

The purpose of this paper is to illustrate the use of a device to quickly perform little holes in the costal lateral arch for synthesis of the standard posterolateral thoracotomy. The working principle of the instrument is similar to that of a hollow punch device. Preliminary laboratory experience allowed to identify the best diameter of the costal holes (2 mm), without fracture. Absorbable suture were passed through the holes and tied to approximate the facing ribs. The modality of costal plane synthesis, very easy and quick with this device, makes possible to prevent intercostal nerve compression and accidental intercostal vessel lacerations. The so frequent, severe and often long lasting painful sequelae of thoracotomy, on the other hand so rare in other surgical wound (i.e. laparotomy, sternotomy, etc.) justify in our opinion the routine use of this costal plane synthesis technique.
