Abstract
BACKGROUND: The aim of this survey was to show mid-term outcomes of a short-stem cementless hip prosthesis with metaphyseal fit and fill. METHODS: Case series is on 74 implants in 67 patients, implanted from June 2006 to December 2010 with an average follow-up of 48 months (range 36-90 months). RESULTS: In their case series, authors found some pitfalls as varus or valgus alignment, heterotopic ossification, aseptic mobilization with subsidency, and malpositioning. According to Harris Hip Score, postoperative clinical outcomes were excellent-good (84 %) and fair-poor (16 %). CONCLUSIONS: At a mid-term follow-up, the investigated implant showed a strong stability and some well-tolerated mechanical and biological pitfalls.
