SYNTECS | Representative orthopedic implant geometries (Acetabular cup and Hip stem)

Life expectancy is rising and so orthopedic implants must be designed for longer lifetimes and with improved properties.

Device manufacturers are seeking solutions to surface engineer implants for improved initial stability, osseointegration and anti-microbial properties.

DLW will be used to produce surface structures to maximise initial implant stability.

DLIP and LIPSS will be used to produce multi-functional textures with controlled roughness. The combination of DLIP, DLW and LIPSS in a single laser processing system may also potentially replace several separate processes and improve overall process sustainability.

Fig. 1: X-ray micro-computed tomography reconstruction of a Pinnacle acetabular cup (DePuy Synthes), similar to components processed in SYNTECS. Key morphometric parameters depicted (porosity, pore size, strut thickness) are indicated. The cross-section shows the porous structure thickness. From Dall'Ava et al. 2020. J Orthop Surg Res.
