A team of Australian researchers recently published a paper on a case involving a 72-year-old woman with sciatica and a complex L5–S1 pseudoarthrosis 12 months after L2–S1 fixation surgery for symptomatic degenerative scoliosis. The woman needed surgery to fix the complications she had developed, and the surgical team treated her using 3D printing from the beginning to the end of the procedure. You can access the paper, entitled “Designing patient-specific solutions using biomodelling and 3D-printing for revision lumbar spine surgery,” here.
CT data from patient scans was used to develop models of the bony lumbosacral spine for pre-operative planning, patient education, and reference during the procedure itself. The surgeon also worked with engineers to develop a patient-specific 3D printed titanium lumbrosacral fixation implant. 3D printing was also used to create a stereotactic drill guide.
“Self-docking 3D-printed nylon tubular retractors specific to patient tissue depth and bony anatomy at L5–S1 were developed for a minimally invasive transforaminal approach,” the researchers add. “The pre-selected screws were separately sourced, bundled with the patient-specific devices, and supplied as a kit to the hospital before surgery.”
The use of 3D printing in spinal surgeries has not only saved people from further discomfort and revision surgeries but has actually saved lives – titanium implants have restored vertebrae and prevented paralysis and even death on more than one occasion. A catastrophic spinal condition, with the loss of vertebrae, sentenced people to a lifetime of disability not long ago, but 3D printing is allowing these people to walk again. The importance of the technology’s ability to create patient-specific implants cannot be overstated; surgeons can now effectively replicate parts of the human body.
We may not yet be able to 3D print transplantable human organs, but 3D printing has still come an incredibly long way in medicine, and spinal surgeries and implants are an excellent example of how technology can restore the body. In time, it’s possible that paralysis may become a rarity, even with severe spinal injuries and conditions. If parts of the spine can be replaced by implants, will we eventually be able to replace the entire spine, or close to it? The possibilities are exciting, but in the meantime, people with less severe spinal conditions are living their lives in much less pain thanks to 3D printing.
Authors of the paper include Ganesha K. Thayaparan, Mark G. Owbridge, Robert G. Thompson, and Paul S. D’Urso.
