Objectives/Interrogation:
- 1.
- Known problems with conventional metal-plates
- 2.
- Comparable usability and results with PEEK-plates
- 3.
- Advantages of PEEK-plates because of radiolucency
Methods: About 20 patients with conventional metal-plates were compared to about 20 cases with PEEK-plates concerning:
- adequate mid-term functional outcome in four-corner-fusion
- X-ray-analysis on accuracy and time of determination of consolidation
Results and Conclusions: PEEK-midcarpal-plates have the same biomechanical potential for similar clinical outcomes as conventional materials, but they offer a much better and earlier evaluation of the fusion rates (Tables).
So PEEK is much more reliable not only for the operating specialist, but also for surgeons outside when deciding the end of splinting and start of physio and increasing load. PEEK even might help shorten rehabilitation time, because assessing the X-rays is reliable earlier and possible for at least two weeks (vs. up to 3 months).
