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.

fig1: Plain AP pelvic radiograph of broken Revitan stem.

Mentions: Four years later, the patient presented with pain in his left hip and some weakness. Clinical examination revealed new shortening of his leg associated with pain on attempted straight leg raising. His BMI was unchanged. Radiographic examination showed a fracture around the Revitan connection taper, which was confirmed following explant of the prosthesis (Figure 1). There was no evidence of infection.
