The literature article entitled ¿survival of monoblock rm vitamys compared with modular pinnacle cups: mid-term outcomes of 200 hips performed by a single surgeon¿, written by eustathios kenanidis, et al, published 6 october 2019 in hip international, was reviewed.The purpose of the article was to compare the mid-term survivorship of the rm pressfit vitamys monoblock cup with the well-documented modular pressfit pinncle cup as a reference.The authors¿ hypothesis was that the monoblock cup would improve mid-term survival compared to the modular uncemented design.Depuy products used: pinnacle cup, corail stem.200 cases were enrolled in the study, 93 patients received the pinnacle cup and 107 received the competitor cup.There was a mean follow-up of 57 months.Adverse events: there was one case of acute deep infection in otherwise stable and well-aligned prostheses in the pinnacle group that was diagnosed at 48 months postoperatively following a uti in a (b)(6) y/o female patient.It was managed with 2-stage revision and an interval of intravenous antibiotics for two weeks followed by oral antibiotics for three months before final re-implantation.There was one case of aseptic loosening in the pinnacle group.The cup was well implanted in a (b)(6) y/o male with a bmi over 40 and height over 180 cm.The patient suffered pain in the groin for a year before undergoing revision of both the acetabular and femoral component.The implants were removed with evidence of poor osseointegration attributed to poor compliance with weight bearing and activity recommendations.There were two hips who showed heterotopic ossification brooker class i at the one-year-follow-up.
