Abstract
BACKGROUND: Carbon-fiber-reinforced Polyetheretherketone (CFR-PEEK) nails are gaining interest as they have biomechanical properties potentially capable of overcoming disadvantages of conventional metal nails. CASE SUMMARY: Three cases are illustrated which required superior mechanical toughness, compatibility with radiotherapy, and postoperative advanced imaging. CONCLUSION: CFR-PEEK nails seem to have a niche role in distinct groups of patients.
