Bone healing under different lay‐up configuration of carbon fiber‐reinforced PEEK composite plates

Abstract

Secondary healing of fractured bones requires an application of an appropriate fixa-tor. In general, steel or titanium devices are used mostly. However, in recent years,composite structures arise as an attractive alternative due to high strength to weightratio and other advantages like, for example, radiolucency. According to Food andDrug Administration (FDA), the only unidirectionally reinforced composite allowed tobe implanted in human bodies is carbon fiber (CF)-reinforced poly-ether-ether-ketone (PEEK). In this work, the healing process of long bone assembled withCF/PEEK plates with cross- and angle-ply lay-up configurations is studied in theframework of finite element method. The healing is simulated by making use of themechanoregulation model basing on the Prendergast theory. Cells transformation isdetermined by the octahedral shear strain and interstitial fluid velocity. The processruns iteratively assuming single load cycle each day. The fracture is subjected to axialand transverse forces. In the computations, the Abaqus program is used. It is shownthat the angle-ply lamination scheme of CF/PEEK composite seems to provide betterconditions for the transformation of the soft callus into the bone tissue.
