Medical technology company Smith & Nephew has unveiled its first 3D printed hip implant at the American Academy of Orthopaedics Surgeons Annual Meeting, taking place in Orlando this week.
The REDAPT Revision Acetabular Fully Porous Cup with CONCELOC Technology is designed for use in revision cases where compromised bones makes implant fixation and stability more difficult. The 3D printed implant allows for bone ingrowth due to is porous structure that mimics cancellous bone.
“We’re excited about the creative possibilities this new manufacturing process holds for surgeons and their patients,” said Mike Donoghue, Vice President of Global Reconstruction at Smith & Nephew. “Bringing to market a 3D-printed titanium acetabular cup for difficult revision procedures is just one example of the potential of this remarkable technology.”
Successful fixation of a porous implant requires that the implant remains in steady, stationary contact with the bone as it heals and new bone grows. For this reason, the new REDAPT cup also uses the new REDAPT Variable Angle Locking Screws, which work within the implant’s unique geometry to provide both compression and a rigid construct to the acetabular shell, as well as traditional, non-locking screws.
Smith & Nephew received Food and Drug Administration 510(k) clearance for the REDAPT Cup in November 2015. It is currently available in select sites in the US.
