Indications • Dorsal stabilisation on the posterior pelvic ring for unstable pelvic ring injures type C/AO, especially in the case of: • Unstable sacral fractures in all three zones • Osteo-ligament instabilities of the sacro-iliac joint SACRAL RODS emergency team for broken bones® Sacral Rods

Sacral Rods The operative management of pelvic ring disruptions has always represented a challenge to the treating surgeon. The sufficient stabilisation of such an injury requires both a profound knowledge of the anatomy and biomechanics of the pelvis and an understanding of the mechanism of fracture. The chosen technique of a posterior stabilisation depends on the one hand on the kind of fracture, and on the other hand on the personal experience of the individual operator. Threaded rods as fixators of posterior pelvic ring instability have been well known and well proven for a long time,...

Description of Surgery Ventral stabilisation As a rule, a ventral stabilisation is carried out as the first intervention since a secondary reposition of the anterior pelvic ring in the case of an already reduced dorsal fracture could lead to an uncontrolled compression of the plexus sacralis. SACRAL RODS emergency team for broken bones® Dorsal stabilisation Dorsal stabilisation is carried out in the prone position of the patient, usually under full anaesthesia and in the same session. A curved skin incision is made on both sides lateral to the sacro-iliac joint, from the spina iliaca...

Preparation Spina iliaca post. superior Preparation of the subcutaneous fat tissue and carried down to the fascia of the glutaeus maximus muscle. Loosen the musculature from the outer surface of the dorsal os ileum. Linea glutea posterior Reposition A possibly necessary reposition of half of the pelvis is carried out by means of a Schanz screw attached to the crista iliaca. Deployment of the guiding instrument and checking by means of image converter. Guiding instrument: It is strongly advised not to use the enclosed guiding device for reducing bone fragments since it could be damaged in...

Spina iliaca post. superior The linea glutea posterior acts as the reference point. The guiding instrument is positioned on a considered line between the origin of the linea glutaea posterior on the iliac crest and the spina iliaca inferior; the drill hole will then lie some 0.5 cm higher. The caudal screw is attached first, and the point of entry is to be chosen such that the rod is at a tangent to the crista centralis of the os sacrum or even perforates it, but at least comes to rest behind the lamina dorsalis of the sacrum. connecting line Linea glutea posterior – spina iliaca post....

The asymmetric washer, nut and locknut are attached (this is done the most simply by continuing to turn the rod with the drill). Both nuts must be definitively tightened. The drill chuck is released, the guiding instrument removed, and the washer is attached as are, successively, both nuts on the second side using the special socket spanner and the soft-part protector. Wedge shaped spacers: Please note the exact anatomical position shown here to arrive at the best result. SACRAL RODS

socket spanner with soft-part protection The first nut is tightened until the desired compression of the fracture area is reached (care must be taken not to use excessive compression with transforaminal fractures of the sacrum.) Both nuts must be tightened. Remove the excess end using the bolt cutters. The same procedure is undertaken with the second screw, which is to be positioned some 2 cm cranially to the first screw. adapter for socket spanner Check Final check using image converter or X-ray, redon drainage, subsequent closure of the wound.
