The supra-acetabular pelvic clamp leads to a homogeneous force distribution to the pelvic ring and enables complete closure of the anterior and posterior pelvic ring in unstable pelvic fractures. Reduction of the intrapelvic volume and compression of the posterior pelvic ring can thus be achieved. Risks for intrapelvic perforation or injuries of vessels and nerves are low. No bacterial contamination of the access for the sacroiliac screw fixation occurs. To avoid overcompression of the unstable pelvic ring, manual or radiological control of the closure of the ventral pelvic ring is necessary.

We were able to establish and validate an MRI-associated classification to graduate the postoperative outcome after MPFL reconstructions. Foresighted, the presented classification might support further decision making in case of unsatisfying postoperative results.
