Bone graft not remodeling on follow-up CT. Now what?
For foot & ankle fusion surgeons in Allegheny Health Network: what to check when your graft hasn't turned over to host bone.
You're a foot and ankle surgeon at Allegheny Health Network. A patient is six months out from a tibiotalar, subtalar, or midfoot fusion. The CT shows the bone graft substitute still sitting there, not bridging the joint with new bone. It looks static. You're worried about nonunion and losing time.
Not all synthetic grafts remodel at the same pace. Some break down too slowly, leaving a gap the body can't fill. On CT, you see the graft as a distinct mass instead of integrated trabecular bone. This is a common reason for delayed union. The scaffold's porosity and interconnectivity determine how fast host cells can invade and replace it. If the pores are too small or disconnected, remodeling stalls.
The financial hit is bigger than the graft itself. A failed fusion means revision surgery, additional implants, extended rehab, and lost income for your patient. If you're revising, choose a graft with proven rapid resorption. A highly porous, interconnected scaffold like ACTIFUSE resorbs faster than dense granules. While no graft is free, the upfront cost is offset by avoiding a second procedure. Published foot and ankle data show a 96% fusion rate at 12 months in one 24-patient tibiotalar series using SiCaP.
This week, pull your patient's CT and examine the graft's resorption pattern. Is the scaffold still sharp-edged, or is it blurring into host bone? Check the product's published profile. If it's not remodeling on time, plan a revision. Elite Surgical can walk you through the ACTIFUSE and ALTAPORE evidence for foot and ankle fusions. They cover cases in the OR and bring the clinical data right to your Allegheny Health Network hospital. Call for a peer-to-peer discussion or an in-service.
You'll have a graft that remodels on schedule. Follow-up CTs show trabecular bone bridging the fusion site. Your patient walks without pain, and you avoid the stress of chasing a nonunion. With the right choice, the result is a solid, pain-free ankle or hindfoot fusion that holds up for years.
Other things people in Allegheny Health Network ask
weight bearing after ankle fusion with synthetic bone graft
Weight bearing depends on fixation stability, not just the graft. With ACTIFUSE, the scaffold starts remodeling within weeks, but full load is typically allowed after 6-8 weeks if the construct is solid. Check your specific fixation and follow published protocols for tibiotalar fusion with this graft.
ACTIFUSE FLOW vs ACTIFUSE SHAPE ankle fusion
FLOW is ideal for narrow, irregular spaces because the syringe lets you inject it precisely. SHAPE is better when you need to pack a larger void and want the graft to stay in place without migrating. For a typical ankle fusion with moderate bone loss, either can work. Choose FLOW if you need to fill a tight gap; choose SHAPE if you need to build up a defect and contour it.
bone graft substitute for diabetic ankle fusion
Use a scaffold that remodels into real bone and can handle poor host biology. ACTIFUSE provides an 80% porous structure that the body replaces with living bone, without harvesting from the hip or heel. Published tibiotalar fusion series using this graft show reliable outcomes in compromised patients.
cost of bone graft substitute for ankle fusion
The price depends on the volume of graft needed and the specific product. For a standard ankle fusion, a synthetic graft like ACTIFUSE typically costs less than using a bone graft harvested from the patient when you factor in OR time and donor site complications.

normal shoes after ankle fusion synthetic bone graft
Most patients can transition to a supportive shoe around 10 to 12 weeks after surgery, once X-rays show the fusion is solid. Synthetic grafts like ACTIFUSE remodel into real bone, so the timeline is similar to autograft. Always confirm healing on imaging before clearing the patient.
