\u201cWithin the last 5 to 10 years there has been a lot more industry that has been capable of quickly turning around custom titanium implants with a textured surface that can achieve osseointegration and be made whatever shape we need it to be made,\u201d Taylor J. Reif, MD,<\/b> an orthopedic surgeon at the Osseointegration Limb Replacement Center at Hospital for Special Surgery, told Healio about results presented at the American Academy of Orthopaedic Surgeons Annual Meeting. \u201cSeeing this trend happening within orthopedics, we applied it to osseointegration. In our case, we thought this is an odd shape to this bone, maybe we should try something custom to get a better fit and then assessing the custom group vs. our prior group.\u201d<\/p>\n

Reif and colleagues retrospectively reviewed all patients who underwent transfemoral, transtibial or transhumeral osseointegration with a custom electron beam melting 3D-printed implant between May 2024 and March 2025. They collected intraoperative distal chip fracture and postoperative adverse events as the primary outcomes, as well as limb deformity-Scoliosis Research Society and Patient-Reported Outcome Measurement Information System outcome scores. These outcomes were compared with a historical control group of patients who received an off-the-shelf osseointegrated implant.<\/p>\n

Taylor J. Reif<\/b><\/strong><\/p>\n<\/div>\n \u201cThe biggest difference we saw was, intraoperatively, the custom implants had a much lower rate \u2014 0% \u2014 when we looked at our initial cohort of fracturing the bone while putting in the implant,\u201d Reif said. \u201cThat makes sense because the implants have been custom fit to that bone, so it tends to go in nicely and fit perfectly.\u201d<\/p>\n
In comparison, results showed the historical control group had a 21.2% rate of intraoperative distal chip fracture. Researchers found all patients progressed to full weight-bearing without loosening, and there were no implant failures, deep infections or unplanned surgeries at an average follow-up of 6 months. Patients with a custom osseointegrated implant had statistically significant improvements in patient-reported outcome measures, according to the abstract.<\/p>\n
\u201cThis is something that we want to continue to evaluate because we know we are going to continue to be in these circumstances where we have oddly shaped bones that we would like to do osseointegration on, and having that option to have a custom fit implant is going to be nice, especially if they function ultimately in the same way as the other implants,\u201d Reif said.<\/p>\n
