You had surgery on a fracture and it's not healing. Or maybe it was managed without surgery and the bone just stopped making progress. Either way, you're still in pain months later, and nobody can tell you why.

That's the situation most of our non-union patients are in when they come to MOTUS. Some of them have already been through a second surgery that didn't work either. The problem isn't that the surgery was bad. The problem is that nobody figured out why the fracture wasn't healing before they went back in.

When a fracture doesn't heal, there's always a reason. It could be mechanical, biological, metabolic, or something as simple as a vitamin deficiency that nobody checked for. Our job is to find that reason first, then fix the fracture. That order matters, because if you skip the first part, you're setting yourself up to be back in the same spot six months from now.

What Is a Non-Union?

A non-union means your fracture has stopped healing and it's not going to finish on its own. Most fractures show real progress by 3 to 4 months. If yours hasn't moved at 6 months, or if the bone has clearly stalled with no sign of bridging across the gap, that's a non-union.

You might hear the term delayed union, which is different. That means the fracture is healing slower than expected but hasn't completely stopped. A delayed union may still get there with time and the right conditions. A true non-union won't.

Here's what to watch for if you think your fracture isn't healing:

• Pain at the fracture site that's still there after 3 to 4 months

• It still hurts to put weight on it or use it normally, and that's not improving

• Your follow-up X-rays aren't showing progress

• You can feel movement at the fracture site where there shouldn't be any

• Your hardware has loosened, bent, or broken

None of these means you definitely have a non-union, but if you're noticing them, you need someone who treats non-unions regularly to take a look.

How We Figure Out Why Your Fracture Isn't Healing

Before we recommend anything, we need to understand what went wrong. We look at four things, and every non-union evaluation at MOTUS covers all of them. Skip one and you're guessing, and guessing is how people end up with a second failed surgery.

1. Is the fracture stable enough to heal?

   Your bone needs to be held still enough for the healing process to work. If there's too much motion at the fracture site, or if the hardware has loosened or worn out, your body can't keep up. We look at the hardware, the alignment, and the whole mechanical setup. Sometimes the original surgery was done well, but the fixation just wasn't strong enough for your activity level or your bone quality.

2. What's going on inside your body?‍ ‍

   A lot of non-unions have a metabolic problem behind them that nobody checked for. Research shows that more than 80% of patients with unexplained non-unions have at least one, things like low vitamin D, thyroid issues, or calcium imbalances. All of them are treatable, but only if someone runs the labs. We also look at your nutrition, your bone quality, and whether any medications you're taking (like ibuprofen or other anti-inflammatory drugs) could be slowing things down. We order labs on every non-union patient. If there's a metabolic problem and nobody fixes it, no amount of hardware is going to make that bone heal.

3. What outside factors are working against you?

   Smoking. Smokers take about 50% longer to heal fractures because nicotine tightens blood vessels and cuts the oxygen supply to healing bone. We have a direct conversation about this with every non-union patient.

   Diabetes.Uncontrolled blood sugar gets in the way of every stage of bone healing. Managed diabetes is a very different situation than unmanaged diabetes, and that distinction matters here.

   Infection. A low-grade infection at the fracture site can quietly block healing without any obvious symptoms. If there's any reason to suspect it, we test for it.

   Activity and follow-up. If you've been putting weight on a fracture that wasn't ready for it, or if you've missed follow-up appointments, that's part of the picture too.

4. What is your bone actually doing at the fracture site? Not all non-unions look the same, and what the bone is doing tells us what it needs.

   Hypertrophic non-union: Your bone is trying to heal. There's new bone forming around the fracture site, but the fragments aren't connecting. This usually means the biology is working fine but the fracture isn't stable enough. If we fix the stability, the bone will heal.

   Atrophic non-union: Your bone has stopped trying. There's no new bone forming, the fracture ends may have rounded off, and the healing process has shut down. This needs more than just new hardware. We have to restart the healing with bone graft or other techniques.

   Oligotrophic non-union: Somewhere in between. There's been some attempt at healing but not enough to finish the job. Getting this right matters. If your bone is already trying to heal and we throw a massive bone graft at it, that's overkill. If your bone has given up and we just put a new plate on without restarting the biology, it's going to fail again.

How We Treat Non-Unions

Once we know why your fracture isn't healing, we build the plan around that. Here's what treatment can look like depending on your situation.

Revision fixation. If the hardware or the mechanical setup is the problem, we may need to replace it. That could mean a bigger plate, a different type of fixation, or switching from a plate to a nail or the other way around.

Bone grafting. If your bone has stopped trying to heal, or if bone has been lost, we use bone graft to give it both structure and the biological kick to restart. Autograft, which is bone taken from your own body (usually your pelvis), is still the gold standard. Donor bone and synthetic options are available when autograft isn't the right fit.

Infection treatment. If infection is the reason your fracture isn't healing, fixing the bone without clearing the infection won't work. That may mean taking out the hardware, cleaning the infection site, a long course of IV antibiotics, and then rebuilding in stages once the infection is gone.

Metabolic correction. If your labs show low vitamin D, thyroid problems, or other issues, fixing those is part of the treatment. It won't replace surgery when surgery is needed, but nothing else we do will work if the foundation isn't right. If this is needed in your case, we have great referral partners that will be included in your care.

What to Expect When You Come In

Non-union treatment isn't quick, and you should know that going in.

Your first visit includes a full evaluation: we review your imaging, run labs, and may order a CT scan so we can see the fracture in detail. Then we sit down with you and talk through what went wrong, what needs to happen, and what the realistic timeline looks like.

If you need surgery, we address both the mechanical problem and the biological one, not just one of them. Most non-union revisions take 3 to 6 months to heal, and complex cases can take longer. You'll have regular follow-up visits with imaging so we can confirm things are actually moving in the right direction.

Our goal is to fix this correctly one time. Doing a revision surgery without figuring out the root cause is like changing the oil without checking the engine. You feel like you did something, but it doesn't solve the problem.
