Revision of failed hip surface replacement arthroplasties with a bipolar prosthesis. Three case reports with two- to three-year follow-up observations.
Three cases of an isolated femoral component failure of a hip surface replacement were treated by use of a press-fit bipolar prosthesis to articulate with the retained acetabular cup. At two to three years post-surgery (average, 31 months), these three conversions had good clinical function and maintained an acceptable radiographic appearance. While no optimal long-term solution currently exists for failed hip surface replacements in young adults, this rather straightforward surgical conversion may have a role to play in the interim management of some of these patients.
