Abstract
Introduction
The Ascension PyroCarbon proximal interphalangeal (PIP) total joint is used in osteoarthritis of the PIP finger joint. No systematic study of the positioning of this prosthesis and its relation to proximal and middle phalanx morphology has yet been reported.
Materials and methods
Positioning of the proximal and distal components of the Ascension PyroCarbon PIP total joint was radiographically analysed in 152 human cadaver fingers.
Results
Ideal implant position in the axis of the phalanx and with contact of the implant head with bone in both the frontal and sagittal planes was seen in only 33 % of the phalanges. Implant malposition was observed in the remaining 67 % of phalanges.
Conclusion
The current design of the Ascension PyroCarbon PIP total joint can lead to malpositioning that we attribute to its incomplete accommodation of the morphology of the proximal and middle phalanx, the surgical challenges the design poses, or both acting together.

Change history
10 November 2017
In the experimental study the distal component of the Ascension PyroCarbon proximal interphalangeal total joint prosthesis was implanted 180° rotated. Figures 2–5 show the implant malpositions. The methods, results, and conclusion of the study were not affected by this.
