Deficiency of the extensor mechanism, instability, dislocation and infection are the most frequent causes described for revision. We report the case of a female patient who underwent a PIP arthroplasty with a pyrolytic carbon implant of her right long finger; she suffered from an implant fracture only 11 months after surgery, a rare complication of this kind of implant; it makes think to fragility of this kind of implant.
