[Pertrochanteric pseudarthrosis. Implant failure - technical error - destiny?].
Pain is not always the leading symptom of a failed union. High primary stability often allows full weight bearing in spite of fracture instability. The difficult diagnosis of a pseudarthrosis is a reason for late intervention. Implant failure and implant breakage are typical signs of surgical underestimation. Finally, the diagnosis "pseudarthrosis" is a fluent one and is defined as a failed fracture healing despite implant stability. Recognition of biological and biomechanical failure, this demands correct evaluation of the global situation and extensive experience in revision surgery on the part of the surgeon.
