3D-printed implants viable for revision lumbar fusion, study shows – 4 insights

Surface Technology

Preoperative planning, along with biomodelling and 3D printing, is a viable process for revision lumbar fusion surgery, according to a case study published in European Spine Journal.  

Here are four things to know:

1. The case involved a 72-year-old woman with sciatica and a complex L5–S1 pseudoarthrosis that developed 12 months after L2–S1 fixation surgery for symptomatic degenerative scoliosis.

2. The surgeon collaborated with engineers and developed a patient-specific, 3D-printed titanium lumbosacral fixation implant.

3. The team simulated the sizes and trajectories for the S2 and iliac screws by using biomodelling to develop a stereotactic 3D-printed drill guide.

4. The patient reported symptom resolution six months after the procedure.
