Smith & Nephew, Andover, Mass., introduces its first 3D-printed titanium hip implant, the new Redapt revision acetabular fully porous cup with Conceloc technology. To support bone growth, the 3D manufacturing process will be used to produce an entirely porous implant, one that mimics the structure of cancellous bone.
The company noted that the Conceloc advanced porous titanium technology is an alternative to external porous coatings, such as sintered beads or fiber mesh, used in other uncemented implants. The new Redapt cup has been developed for use in revision cases where compromised bone makes implant fixation and stability more difficult.
“Bringing to market a 3D-printed titanium acetabular cup for difficult revision procedures is just one example of the potential of this remarkable technology,” says Smith & Nephew global reconstruction vice-president Mike Donoghue.
Redapt variable-angle locking screws, as well as traditional non-locking screws, work within the implant’s geometry to provide both compression and a rigid construct to the acetabular shell. The 3D-printed titanium hip implants are available at selected sites in the United States.
