3D printing is enabling a new era of personalized orthopedic implants. Using CT or MRI data, engineers design implants that precisely match a patient's unique anatomy, then manufacture them from medical-grade titanium using selective laser sintering or electron beam melting. These custom implants feature porous surfaces that promote bone ingrowth and can fill complex bone defects that standard off-the-shelf implants cannot address.
In Alaska, 3D-printed implants are increasingly available for total ankle replacement, revision hip and knee surgery, complex fracture reconstruction, and tumor surgery where bone has been removed.
Frequently Asked Questions
What are 3D printed orthopedic implants made of?
Most 3D printed orthopedic implants are made from medical-grade titanium alloy (Ti6Al4V) using additive manufacturing processes. The porous structure mimics cancellous bone and promotes biological fixation through bone ingrowth.
When are custom 3D printed implants needed?
Custom implants are used when standard off-the-shelf implants cannot adequately address the patient's anatomy, such as in revision surgery with significant bone loss, complex deformities, tumor reconstruction, or when standard implant sizes don't fit.
How long does it take to make a custom 3D printed implant?
From CT scan to finished implant typically takes 4-8 weeks, including design, engineering review, manufacturing, and quality testing. This is planned in advance of the scheduled surgery date.
