After open-heart surgery, the sternum is closed with stainless-steel wires or plates that hold the bone edges together while healing.
You go to sleep with anesthesia, your heart team does the needed repair, and before the surgeons finish they close the breastbone. The closure is a careful, mechanical process designed to keep the bone steady while it heals. The materials stay inside the chest and the skin is sealed on top.
Many readers ask, “how is the sternum closed after open heart surgery?” The plain answer is wires for most, plates for some, and skin closure above that. The aim is a firm chest wall that lets you breathe, cough, move, and heal.
Step-By-Step Sternum Closure Overview
Here’s a plain-language walk-through of the closure. In many hospitals this takes only a few minutes at the end of the case, but the setup and checks are exacting.
Aligning The Bone
The two halves of the sternum are gently brought together after the heart work is complete. Any rough edges are trimmed. Surgeons clear away debris and blood so the bone surfaces meet cleanly.
Passing The Wires Or Plates
Most closures use stainless-steel wires passed through tiny holes in each half of the bone. The ends are twisted to draw the halves together. Some patients benefit from rigid plates with screws that span the cut and create a flat, stable bridge.
Tensioning And Testing
The team tightens the wires or secures the plates, then checks chest movement with breathing pressures. A stable chest wall with no rocking is the goal. If needed, extra loops or a plate are added for more hold.
Layers Closed Above The Bone
After the bone is steady, soft tissues and skin are closed with sutures or staples. Drains may be placed to carry away fluid. A clean dressing finishes the job.
Sternum Closure After Open-Heart Surgery: Methods And Materials
Surgeons choose from a small toolkit. The classic method remains wire cerclage. Over the past two decades, rigid plate fixation has grown for selected patients. Cables, bands, and clamp-style devices exist as well. For a patient-friendly overview, see the Cleveland Clinic sternotomy page.
| Technique | What It Uses | Typical Cases |
|---|---|---|
| Wire Cerclage | Stainless-steel wires looped through the sternum and twisted | Standard adult cases; reliable, quick, time-tested |
| Figure-Of-Eight Wiring | Wires crossed in an “8” pattern for extra grip | Fragile bone, deep chest, or added stability needed |
| Rigid Plate Fixation | Titanium plates and screws spanning the cut | Obesity, osteoporosis, redo sternotomy, or high risk for dehiscence |
| Cables/Bands | High-strength cables or polymer bands | Alternative to wires in selected settings |
| Clamp Devices | Metal clamps that lock over bone edges | Special situations or surgeon preference |
| Adjunct Weaves | Patterns like the Robicsek weave | Added hold along the rib cartilages |
Wire Cerclage: The Baseline Approach
Steel wires are strong, thin, and biocompatible. A typical adult chest takes eight to twelve loops, spaced from top to bottom. The surgeon may pick simple loops or a figure-of-eight pattern. The twists are snug, then folded flat so they don’t poke.
Rigid Plates And Screws
Plates give “rigid fixation,” which limits micro-motion and can ease pain with coughing or turning. Many centers use them for people with weak bone, repeat chest entry, high body mass, or a wide, deep chest. Studies show fewer sternal problems in these groups, with costs that can even out when fewer complications occur.
Hybrid And Special Devices
Surgeons sometimes combine plates and wires. There are clamp systems that lock over the bone, and high-strength cable sets. Choice depends on anatomy, risk, and hospital inventory.
Step-By-Step Inside The Operating Room
1) Bone Edges Prepared
After the heart work, the cut bone edges are cleaned. Bone wax may be used lightly to slow bleeding. The edges are matched so the front and back plates meet.
2) Wires Or Plates Positioned
Wires pass through pre-made holes with a needle driver or a drill makes tiny holes in hard bone. If plates are used, pilot holes are drilled and screws are set to the maker’s torque spec.
3) Tension Applied
Each wire is tightened in sequence to spread the load. With plates, screws are seated across the midline. The chest is inflated to test the hold while the team watches for any click or shift.
4) Final Layers Closed
Soft tissue layers close with absorbable sutures. Skin closes with sutures, staples, or a glue strip. A sterile dressing goes on and the drapes come off.
Why Surgeons Pick One Closure Over Another
No single method fits everyone. The decision weighs bone density, chest shape, weight, diabetes, smokers’ lung cough, steroid use, kidney disease, and whether this is a first or repeat chest entry. The target is a steady chest today and fewer wound issues next week.
Wire cerclage suits most adults and keeps time under anesthesia short. Plates add cost and a bit of setup time, but can pay back in fewer wound issues for people at higher risk. Your team explains the plan before surgery and may show you a model plate or the size of a wire loop.
What Stays In The Body And For How Long
The wires or plates are meant to stay in place for life. They are metal, but tiny and well-tolerated. Skin counters the idea that they must come out; removal is rare and reserved for pain from a prominent twist, infection, or a later chest re-entry.
Many people can feel a small bump under the skin where a twist lies. That’s normal. Some feel brief twinges months later as nerves wake up. Ordinary airport scanners are usually fine. Modern MRI scanners can image safely with standard sternal wires; the radiology team checks device details before any scan.
Home Care After A Sternotomy Closure
Clean, dry, and watchful care keeps healing on track. Wash hands, keep the dressing as directed, and let water run over the incision in the shower once your team allows it. Pat dry. Skip soaking baths early on. Look daily for redness, swelling, warmth, or drainage.
Pain control helps you move and breathe. Many centers taper narcotics within days and rely on acetaminophen and ice. A cough pillow across the chest eases the strain when you cough or get up. Sleep on your back or side with pillows set to your comfort.
Activity Guardrails For The First Weeks
Fresh bone needs time. For six to eight weeks, keep lifting light and use both arms together for tasks like pushing up from a chair. Many teams set a 5–10 lb limit early on and then relax it. Long walks are welcome. Pace up day by day.
Avoid one-arm overhead work or heavy pushing and pulling. Avoid driving until your team clears you. Most people feel steadier by week six and move toward normal by about three months.
Possible Problems And What To Do
Call your team for red streaks, fever, more drainage, a bad smell, a new gap, or a crackling sound. New clicking under the skin or pain that climbs while you rest can signal movement at the bone. Early checks catch small issues before they snowball.
Deep infections are uncommon but serious. Teams lower risk with sterile prep, antibiotics, tight blood sugar control, and careful closure. For policy guidance on reducing surgical site infection risk, see the NICE guideline on surgical site infection.
Recovery Timeline And Milestones
Healing speeds vary, but many patterns repeat. Bone starts to knit by six to eight weeks. Stamina returns in steps. The scar softens over months. Cardiac rehab, if offered, brings guided activity and a watchful eye on blood pressure and heart rate.
| Timeframe | What You May Feel | Helpful Tips |
|---|---|---|
| Week 1–2 | Tender chest; low energy; short walks | Use a cough pillow; keep pain meds on schedule; short, frequent walks |
| Week 3–4 | Less soreness; longer walks; better sleep | Add easy chores; keep arms moving together; watch the incision daily |
| Week 5–6 | More stamina; light chores feel easier | Ask about driving; keep lifting light; start gentle stretches if cleared |
| Week 7–12 | Bone knit in most; steady gains | Increase lifting in steps; resume tasks as cleared by your team |
| After 3 Months | Near-normal routine for many | Cardiac rehab if offered; keep walking; add strength work as advised |
Skin, Scars, And Sensation
Skin edges are closed with staples or sutures; removal timing varies by surgeon. Glue strips may cover the line. Itching, numb spots, and tiny shooting zaps are common while nerves wake. Sun can darken a fresh scar, so keep it covered early on.
A balanced diet with enough protein and calories gives your body the raw material to mend. Hydration matters. People with diabetes track sugars closely, since high readings can slow healing.
How This Fits With Breathing And Coughing
After chest surgery, deep breaths and a good cough keep the lungs clear. A firm closure lets you do that without shearing the bone. An incentive spirometer helps. Strong pain control for the first few days makes these drills easier.
Imaging And Metal Inside Your Chest
Sternal wires and plates are usually safe with routine X-rays, CT, and MRI. Tell imaging staff about your closure hardware. They’ll confirm details and scan settings. Airport metal detectors may beep, but most people pass through without delay.
When Wires Or Plates Need Removal
Removal is rare. Reasons include pain from a prominent twist, a wire that broke after healing, or infection. Many small wire breaks happen long after the bone is solid and cause no trouble. If a piece bothers you, surgeons can trim or remove it through a small cut.
What Patients Usually Feel Day To Day
Early on, pulling and tightness across the chest are common. Sneezes sting. A pillow hugged to the chest can steady things when you cough, laugh, or stand. Gentle shoulder rolls keep stiffness away. If a move hurts sharply, back off and try a smaller range.
Some people feel small clicks in the first weeks. These often fade as swelling drops and muscles settle. New or loud clicks late in healing deserve a call to your team.
Daily Life Tips That Protect The Closure
Keep items at counter height to avoid long reaches. Use a backpack or a cross-body bag with light loads. For car rides, place a soft pad between the seat belt and the chest. Ask friends to carry groceries in the first weeks. Set timers to remind you to walk.
Sleep is easier in a recliner or with extra pillows at first. Short naps refresh you without leaving you groggy. Drink water through the day and eat small, frequent meals if appetite is low.
Words You Can Use With Your Team
If you want a one-line answer you can repeat to others, try this: “how is the sternum closed after open heart surgery?” It keeps the chat clear and invites a simple, direct reply. You can also ask which closure you had and why it fit your body.
Bring up driving, lifting, work return, and rehab dates. Ask how to shower with your dressing and who to call after hours. Clear plans lower worry and make home days smoother.

Frequently Asked Questions
Can The Wires Break?
Small breaks can show on X-ray months or years later after the bone is already solid. Many cause no pain and need no action. Painful spots or a sharp bump can be trimmed or removed.
If you feel snapping or new movement early on, call your team. Early checks can stop a small issue from growing.
Do Plates Set Off Airport Scanners?
Most people walk through with no delay. Carry your surgery card if you have one. If a screener asks, say you have sternal hardware. A quick wand scan clears things up.
How Soon Can I Sleep On My Side?
Side sleeping is fine once pain allows. A pillow hugged to the chest can ease turning. Many people switch sides by week two or three, then sleep more deeply as pain fades.
What Activities Are Safe In The First Month?
Short walks, gentle stretches, and light chores are fine. Keep lifting light and use both arms together. Skip heavy pushing, pulling, and one-arm overhead work until cleared.
Will I Always Feel The Wires?
Some feel small bumps under the skin. Many forget about them once the area settles down. If a spot stays sore or rubs on clothing, ask about local padding or removal.
Wrapping It Up – How Is The Sternum Closed After Open Heart Surgery?
Surgeons close the sternum with wires, plates, or both to build a firm bridge while bone heals. The hardware stays in place and the skin seals on top. Most people feel steadier by six to eight weeks and resume normal life by about three months.
Your best next steps are simple: keep the wound clean, walk daily, use pain meds as directed, and follow the limits your team sets. If something looks off or pain spikes at rest, call early. With steady care, the chest heals and the hardware fades into the background.
