Hip replacement with a versafit dm.The reaming and the trial of the cup were done, finally, the cup versafit dm ø 50 was chosen as the definitive cup; the implant was coupled with the impact ring size 50 with its multifunctional impactor handle and the cup was impacted.When the impacting ring was going to be disassembled from the cup, this piece did not loosen; for that reason, the surgeon had to remove the cup with the related impact ring.The process was repeated and the same situation happened.Therefore, to position and impact the cup, the surgeon used the same multifunctional impactor handle with the correction impaction sphere ø 33 for metal back (ref.01.26.10.0017).
