title: Mechanical and biological results of short-stem hip implants: consideration on a series of 74 cases.
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.
