AIM:The lowering of the age of patients undergoing hip replacements, the rise in functional requests and the increased average age of the population has meant that implants have to be carried out with the greatest possible tissue saving and preservation of bone stock in view of probable revision. The purpose of the present paper was to assess the Silent® (DePuy) neck sparing prosthesis.
METHODS: Twenty patients of average age 46 have been operated on since January 2010 at the Humanitas Gavazzeni Bergamo Orthopedics Unit with the implant of a Silent® (DePuy) neck sparing prosthesis. Results are analyzed with an 18-month follow-up. Aspects of the surgical technique are presented together with the problems encountered during this preliminary experience.
RESULTS:The Silent® stem implant is an effective procedure for removing pain and restoring functionality, it is not more difficult than a traditional implant but different and suggests that a revision operation will be easier.
CONCLUSION:Higher numbers and longer follow-ups are necessary for confirming survival and the positivity of the clinical outcome.
