Revision of a fractured uncemented revision stem using a custom designed punch and retrograde through-knee approach.

Nasr PJ, Keene GS - Case Rep Orthop (2015)

Bottom Line: We report a unique case of a fractured modular cobalt chromium connection taper Revitan (Zimmer, Warsaw, IN) revision prosthesis.Macroscopic examination revealed a fracture at the diaphyseal-metaphyseal junction of this modular component.We also describe a unique method of retrieval for a broken well fixed uncemented femoral stem, using a custom designed extraction instrument via a through-knee approach.

ABSTRACT
We report a unique case of a fractured modular cobalt chromium connection taper Revitan (Zimmer, Warsaw, IN) revision prosthesis. Macroscopic examination revealed a fracture at the diaphyseal-metaphyseal junction of this modular component. This report highlights that fractures can still occur with modern modular prostheses. We are not aware of any published failures of the Revitan revision prosthesis. We also describe a unique method of retrieval for a broken well fixed uncemented femoral stem, using a custom designed extraction instrument via a through-knee approach.

Mentions: Thereafter, the stem was revised to a cemented CPT size 4 extended offset 200 mm stem (Zimmer, Warsaw, IN) (Figure 4). There were no immediate postoperative complications and the patient was discharged on day 5. Subsequent followup has been unremarkable with no symptoms of knee pain and a well functioning revision hip replacement.
