Pediatric Fracture Surgery

Introduction

If your child has broken a bone and the doctor has recommended surgery, this guide is for you. Most childhood fractures heal well with a cast or splint alone. But some fractures — because of where they sit, how the bone pieces have moved, or because a growth plate is involved — need an operation to line the bone up correctly and hold it in place while it heals.

Pediatric fracture surgery is the general name for these operations. The aim is twofold: to restore the shape and function of the bone now, and to protect the child’s future growth. Children’s bones are not just smaller versions of adult bones. They heal faster, they can remodel small imperfections as the child grows, and they contain active growth plates — soft areas of cartilage near the ends of long bones where new bone is made. These differences shape every decision the surgical team makes.

This article walks you through what pediatric fracture surgery involves, the main surgical approaches used, what the day of surgery looks like, recovery week by week, and what to watch for in the months and years afterwards. It is written for parents whose child has already been seen by a doctor and who are now planning the next step.

What Is Pediatric Fracture Surgery?

Pediatric fracture surgery is an operation to realign and stabilise a broken bone in a child or adolescent when non-surgical treatment — usually a cast or splint — will not give a good result on its own. The surgeon may use small metal pins, plates, screws, flexible rods, or an external frame, depending on which bone is broken, how it broke, and the child’s age.

The phrase covers a wide range of operations. A toddler with a displaced elbow fracture, a school-aged child with a forearm break that will not stay aligned in a cast, and a teenager with a broken femur after a sports injury may all undergo “pediatric fracture surgery,” but the actual operations look very different.

What unites them is the underlying principle: in a growing child, the surgeon must restore alignment without damaging the growth plates and without disturbing the natural healing capacity of young bone. This is why fracture surgery in children is a sub-specialty in its own right, and why pediatric orthopedic surgeons spend years training specifically in it.

How children’s bones are different

A few features of children’s bones are worth understanding before reading the rest of this article:

• Growth plates (physes). These are layers of cartilage near the ends of the long bones. They are where new bone is laid down as the child grows. A fracture that runs through a growth plate is treated with extra care because damage here can lead to a limb growing crooked or shorter than the other side.
• The periosteum. This is a thick, tough sleeve around children’s bones. It holds fragments together and supplies blood for healing. It is one reason children heal faster than adults.
• Remodelling. Children’s bones can correct small angles and offsets as they grow. This means that minor imperfections in alignment, which would be a problem in an adult, may simply disappear in a child — especially a young child with years of growth ahead.
• Speed of healing. A broken bone in a young child may heal in three to six weeks. The same fracture in an adult can take twice as long.

Why Pediatric Fracture Surgery Is Performed

Most childhood fractures — probably the large majority — are managed without surgery. A cast, a splint, or a closed reduction (where the surgeon realigns the bone gently from the outside, under sedation or anaesthesia, without making a cut) is often enough. Surgery is considered when one or more of the following is true:

• The fracture is significantly displaced and cannot be held in good alignment with a cast.
• The fracture is unstable — the bone ends shift each time the limb moves.
• A joint surface is involved. When the broken line runs into a joint, even small steps in the bone surface can cause stiffness or arthritis later in life.
• A growth plate is involved in a way that needs precise repositioning. The Salter-Harris classification, which surgeons use to describe growth plate fractures, helps decide which patterns benefit from surgery.
• The fracture is open — the bone has broken through the skin. These need urgent surgical cleaning and stabilisation to reduce the risk of infection.
• There are multiple fractures or other injuries that make casting impractical.
• Nerves or blood vessels are at risk from the position of the broken bone.
• The child is older, with less growth left for natural remodelling, so the surgeon may accept less imperfection before recommending an operation.

The decision is always individual. A 4-year-old and a 14-year-old with the same X-ray may receive different recommendations because the younger child has more growth left to correct minor offsets.

Who Is a Candidate?

Any child with a fracture meeting one of the criteria above may be considered. In practice, the surgical team will weigh:

• The child’s age and remaining growth. Younger children remodel more, so the threshold for surgery is sometimes higher in toddlers and lower in adolescents.
• The bone involved. Some bones tolerate imperfect alignment well (such as the clavicle, or collarbone, in young children); others do not (such as the bones around the elbow or ankle).
• The fracture pattern. Spiral, comminuted (broken into multiple pieces), and intra-articular (joint-involving) patterns more often need surgery.
• The child’s overall health. Underlying bone conditions, nutritional status, and any previous injuries to the same limb are considered.
• Time since the injury. A fresh fracture is easier to realign than one that is several days old and has started to heal in a poor position.

For open fractures or fractures with a vascular or nerve injury, surgery is usually urgent — sometimes within hours of arrival at the hospital. For most other fractures, surgery is planned within a day or two of the injury.

Alternatives to Surgery

Before agreeing to surgery, parents often want to understand what the non-surgical options are. This is reasonable. The main alternatives are:

Casting

A cast made of plaster or fibreglass holds the limb still while the bone heals. Casting works well when the fracture is in a stable position, or has been realigned and will stay aligned. Many forearm, lower-leg, and ankle fractures in children are treated this way.

Splinting

A splint is a partial cast, often used for the first few days when swelling is still building up, or for fractures that need only short-term immobilisation. Splints are sometimes used as the definitive treatment for small, stable fractures.

Closed reduction

In closed reduction, the surgeon realigns the bone by carefully manipulating the limb from the outside, without making an incision. This is done under sedation or general anaesthesia. A cast is then applied to hold the new position. Many displaced fractures are treated this way, especially in younger children. If a closed reduction holds well on X-ray, no further surgery is needed.

Functional bracing or activity modification

For some fractures — certain clavicle fractures, some toe and finger fractures, some buckle (torus) fractures of the wrist — the child wears a sling, brace, or removable splint and avoids activities that stress the bone for a few weeks. Recovery can be excellent.

The surgeon will explain why your child’s particular fracture does or does not fit one of these non-surgical paths. Asking the question — “is there a non-surgical option, and what are its trade-offs?” — is a fair part of any pre-surgery conversation.

Surgical Approaches

Closed reduction and percutaneous pinning (CRPP)

In this technique, the surgeon realigns the bone without making a large incision. Once the bone is in position, thin metal pins (called Kirschner wires, or K-wires) are passed through the skin and across the fracture to hold it. A cast is usually applied on top.

CRPP is one of the most common operations in pediatric orthopedics. It is widely used for:

• Supracondylar humerus fractures (a common elbow injury in young children)
• Some wrist and forearm fractures
• Certain ankle fractures

The pins are usually removed in the clinic, often without further anaesthesia, three to six weeks later when the bone has healed enough to be stable on its own.

Open reduction and internal fixation (ORIF)

If the bone cannot be realigned through the skin, the surgeon makes an incision to expose the fracture directly. The bone pieces are then put back together (open reduction) and held with metal plates, screws, or wires (internal fixation).

ORIF is used for:

• Fractures that enter a joint, where the joint surface must be reconstructed exactly
• Severely displaced or comminuted fractures
• Some growth plate fractures (Salter-Harris types III and IV) where the alignment must be precise
• Fractures that have failed to align with closed methods

The hardware (plates and screws) may stay in place permanently or be removed later, depending on the child’s age, the location of the implant, and the surgeon’s preference.

Flexible intramedullary nailing

For longer bones — particularly the femur (thigh bone) and sometimes the tibia (shin), forearm bones, or humerus — surgeons may use flexible metal rods that are passed through the inside of the bone (the medullary canal) from small incisions near each end. The rods bend gently as they are inserted and act like internal splints.

This technique is widely used in school-aged children with femur fractures. It allows earlier mobilisation than older methods such as full body casts or traction. The rods are typically removed in a planned operation after the bone has healed, usually six months to a year later.

External fixation

In external fixation, pins or wires are placed through the skin into the bone above and below the fracture, and connected to a frame on the outside of the limb. The bone is held in alignment from outside the body.

External fixators are used in specific situations:

• Severe open fractures with a lot of skin and soft tissue damage
• Highly unstable fractures, especially after major trauma
• As a temporary measure until the soft tissues are ready for definitive surgery
• Some complex fractures around joints

External fixators look intimidating but are well tolerated by children. The frame stays on for several weeks while pin sites are kept clean to prevent infection.

Growth-plate-sparing techniques

When a fracture runs near or through a growth plate, the surgeon takes special care with implant choice and placement. Smooth K-wires, rather than threaded screws, may be used across a growth plate because they are less likely to cause growth disturbance. Screws are placed alongside, rather than across, the growth plate where possible. These details are part of the routine practice of pediatric orthopedic surgery.

Preparing for Surgery

Once surgery has been planned, the team will prepare your child medically and prepare you with information. The exact steps vary depending on whether the surgery is urgent (within hours) or planned (within a day or two), but typically include:

Medical assessment

The anaesthesia team will check your child’s general health, ask about any medical conditions, allergies, and medications, and review any previous problems with anaesthesia in the family. Routine blood tests are usually done. For most healthy children, no extra investigations are needed.

Fasting

Children are asked not to eat or drink for a set period before anaesthesia — usually six hours for solid food, four hours for breast milk, and two hours for clear fluids. The team will give you exact times. Following the fasting instructions reduces the risk of complications during anaesthesia.

Imaging

X-rays are usually taken on the day of injury and may be repeated just before surgery. For complex fractures, a CT scan or MRI may have been done to map the fracture in three dimensions or to assess the growth plate.

Talking to your child

Children handle surgery better when they have a simple, honest explanation suited to their age. You do not need to use clinical terms. A short, calm description — “the doctors are going to fix your bone while you sleep, and when you wake up, your arm will be in a cast” — helps more than detailed warnings. Many hospitals have child life specialists who can prepare children with play, books, or a tour of the ward.

Practical preparation

• Pack a small bag with comfortable clothes (loose enough to fit over a cast), favourite toys or comfort items, and any regular medications.
• Arrange care for siblings.
• Plan how you will get home with a child in a cast or splint — a back seat with space for an elevated arm or leg is useful.

What Happens During Surgery

Most pediatric fracture surgery takes place under general anaesthesia, meaning the child is fully asleep and feels nothing. The duration depends on the fracture and the technique, ranging from under an hour for a simple pinning to several hours for a complex reconstruction.

The usual sequence is:

1. Anaesthesia. The child is taken into the operating room, often with a parent present until they are asleep, depending on hospital policy. Anaesthesia may begin with a mask (gas) for younger children, then a drip is placed once they are asleep.
2. Positioning and preparation. The limb is cleaned with antiseptic and draped. The team uses a special live X-ray machine called a fluoroscope to see the bone during surgery.
3. Realignment. The surgeon realigns the bone pieces. For closed techniques, this is done through the skin. For open techniques, an incision is made.
4. Stabilisation. Pins, plates, screws, rods, or an external frame are placed to hold the bone in position.
5. Imaging check. X-rays are taken in the operating room to confirm good alignment and correct hardware placement.
6. Closure. Any incisions are closed with stitches, often dissolvable. The limb is placed in a cast, splint, or dressing.
7. Recovery. The child is woken up in the recovery area, where they are monitored until they are alert and comfortable.

Hospital stay varies. Some operations — particularly outpatient pinning — allow children to go home the same day. Others, such as femur fixation, may require one to several nights in hospital.

Recovery and Healing

The first few days

Pain is usually controlled with simple medications such as paracetamol and ibuprofen, sometimes with a stronger painkiller for the first day or two. Swelling is common and is managed by keeping the limb elevated — arm in a sling above heart level, leg on pillows.

Parents are taught how to:

• Watch for warning signs in the fingers or toes (described below)
• Keep the cast or dressing dry
• Care for pin sites if an external fixator has been used
• Recognise normal versus concerning pain

The first few weeks

Children are usually seen back in the clinic within one to two weeks for an X-ray to check that the alignment is still good. The cast may be changed at this visit if swelling has gone down. Activity is restricted — no sports, no climbing, no rough play — but everyday school attendance is often possible after the first week, depending on which limb is affected and the child’s pain.

Mid-recovery

Between roughly four and eight weeks, depending on the fracture, the bone has healed enough to be stable on its own. Pins placed through the skin (as in CRPP) are usually removed at this stage. Casts come off. The child often feels well and may want to return to full activity sooner than is safe — the bone is healed enough not to move, but not yet at full strength.

Returning to function

After the cast comes off, the limb is often stiff and a little weaker than the other side. For many children, normal play and gentle daily use restore strength and motion without formal therapy. For some — particularly after elbow, knee, or ankle fractures — physiotherapy is helpful for a few weeks to restore range of motion.

Return to sport and high-impact activity

Return to contact sports, gymnastics, or other high-impact activities is usually delayed until the bone has fully consolidated on X-ray and full strength has returned. This is often around three months after surgery, but timelines vary. The surgeon gives clearance based on examination and imaging.

Hardware removal

Whether and when implants are removed depends on what was used:

• K-wires (pins) are almost always removed once the bone has healed.
• Flexible intramedullary nails are usually removed in a planned operation several months later.
• External fixators are removed once the bone is healed, sometimes in the clinic, sometimes in the operating room.
• Plates and screws may be left in place permanently in many cases. They are sometimes removed if they cause discomfort, irritation, or interfere with growth, but this is an individual decision.

Risks and Complications

Pediatric fracture surgery is generally safe in experienced hands, and complications are uncommon. Even so, every operation carries some risk, and parents should understand what those risks are before agreeing to surgery.

Possible complications

• Infection. Risk is low for closed procedures and somewhat higher for open fractures. Antibiotics and careful wound or pin-site care reduce the risk.
• Bleeding. Usually minor and self-limiting.
• Anaesthesia complications. Rare in otherwise healthy children. The anaesthesia team will discuss any specific concerns.
• Damage to nerves or blood vessels near the fracture, either from the injury itself or, less commonly, from the operation.
• Growth disturbance. If the growth plate is injured by the original fracture or, very rarely, by the surgery, the limb may grow unevenly, leading to a difference in length or angle. This is the reason close follow-up over months and sometimes years is part of pediatric fracture care.
• Malunion — the bone heals in a slightly wrong position. Minor malunions may remodel over time. Significant ones may need further treatment.
• Non-union — the bone fails to heal. This is uncommon in children.
• Hardware problems. Plates, screws, or pins can sometimes irritate the skin, loosen, or break. This may need a small revision operation.
• Joint stiffness, especially after fractures around the elbow, knee, or ankle. Most cases improve with normal use or physiotherapy.
• Compartment syndrome. A serious but uncommon condition where swelling inside a tight muscle compartment cuts off blood supply. It is more common after certain high-energy fractures (such as forearm and tibia fractures) and is one of the things the team watches for closely after surgery.

When to seek urgent help after surgery

After your child goes home, contact the surgical team urgently if you notice:

• Severe, increasing pain that is not controlled by the prescribed medications
• Fingers or toes that become numb, very pale, blue, very cold, or that the child cannot move
• A cast that becomes very tight, or that becomes loose
• Fluid, blood, or pus soaking through the cast, or a bad smell from the cast
• Fever above 38°C (100.4°F)
• Redness, swelling, or discharge at incision sites or pin sites

The vast majority of children who have fracture surgery recover fully and return to all the activities they enjoyed before. Bones heal, strength returns, and life resumes. There are, however, a few longer-term considerations worth understanding.

Growth follow-up

When a fracture has involved a growth plate, or has been near one, the surgeon will usually arrange follow-up visits over months — and sometimes a year or more — to make sure the bone continues to grow normally. This may involve repeat X-rays comparing the two sides. If a growth disturbance starts to develop, it is much easier to address early.

Limb length and alignment

In a small number of children — mostly after severe fractures or significant growth plate injuries — the affected limb may grow slightly longer, shorter, or with a slight angle compared to the other side. Many small differences are not noticeable. Larger differences can be addressed with shoe lifts or, occasionally, further surgery in adolescence. Pediatric orthopedic surgeons monitor for this routinely.

Joint movement and strength

After cast removal, the limb feels stiff and looks thinner than the other side because muscles waste during immobilisation. Children typically rebuild strength and motion quickly through normal play. Specific exercises or physiotherapy may be advised for elbow, knee, or ankle fractures.

Implants left in place

If plates, screws, or other hardware are left inside, most children live with them without any problem. Some hardware can set off airport metal detectors but does not interfere with future MRI scans (modern implants are MRI-compatible — the surgical team can give documentation if needed). If hardware causes irritation or discomfort years later, removal is a small operation.

Psychological recovery

It is normal for children to be cautious or even fearful about the activity that caused the injury — the trampoline, the bicycle, the sport. Most children regain confidence with time, gentle return, and parental support. A small number remain anxious; talking openly about the fear and reintroducing the activity in small steps usually helps.

Future fractures

Having one fracture does not mean a child is destined to have more. Good nutrition (including adequate calcium and vitamin D), safe play environments, and protective equipment for sport help reduce the risk of repeat injuries. If a child has multiple fractures from minor injuries, the doctor may investigate whether there is an underlying bone or metabolic condition.

Choosing a Surgeon and Hospital

Pediatric fracture surgery is a specialised area. When you have a choice, useful things to look for include:

• A surgeon with training and ongoing experience in pediatric orthopedics, not only adult orthopedics
• Experience with the specific type of fracture your child has — particularly growth plate injuries
• A hospital with pediatric anaesthesia, pediatric nursing, and child-friendly facilities
• Access to pediatric radiology and rehabilitation services
• Clear communication — you and your child should feel able to ask questions and get understandable answers

It is reasonable to seek a second opinion before any non-emergency surgery, particularly for complex fractures or when the recommendation is unclear.

Frequently Asked Questions

Will my child’s bone heal as straight as it was before?

In most cases, yes — especially when surgery has been done by an experienced pediatric orthopedic surgeon. Children’s bones also have the ability to remodel minor imperfections as they grow, which is one of the advantages of being young.

Will the fracture affect my child’s growth?

Most pediatric fractures, including those needing surgery, do not affect long-term growth. The risk is higher when a growth plate has been injured, which is why these fractures are followed closely for months or years afterwards. If a problem starts to develop, it can usually be addressed early.

How long will my child stay in hospital?

This varies. Some operations — such as percutaneous pinning of an elbow fracture — allow same-day discharge. Others, such as fixing a femur fracture, may need one to several nights. The team will give you an estimate before surgery.

Will my child need physiotherapy?

Many children recover full function with normal play and do not need formal therapy. Physiotherapy is more often used after fractures around joints (especially the elbow, knee, and ankle) and when stiffness persists after cast removal.

When can my child go back to school?

Many children return to school within one to two weeks of surgery, depending on which limb is affected and how comfortable they are. A child with a cast on a leg may need a wheelchair or crutches initially. Schools usually accommodate temporary restrictions.

When can my child play sports again?

Light, non-contact activity often resumes a few weeks after surgery. Contact sports, gymnastics, and high-impact activity are usually held back until the bone has fully healed and strength has returned — commonly around three months, though this varies. The surgeon gives final clearance after examination and X-rays.

Will the metal implants stay in forever?

It depends on what was used. Pins are almost always removed. Flexible rods are usually removed in a planned second operation. Plates and screws are often left in place if they are not causing problems, but can be removed later if needed. The surgeon will explain the plan for your child’s specific implants.

Is fracture surgery painful for children?

Pain is part of any operation, but it is usually well controlled with simple medications taken on a schedule for the first few days, and as needed afterwards. Most children are noticeably more comfortable within a few days of surgery than they were before, because the bone is now stabilised.

Can my child shower or bathe with a cast on?

Standard plaster and fibreglass casts must stay dry. Waterproof cast covers are available, and waterproof linings are an option for some casts. The team will explain what is allowed for your child’s specific cast.

What if my child’s fracture was missed at first and is already a few days old?

Surgery is often still possible. Fresh fractures are easier to realign, but children with fractures that are several days old can still be treated successfully. The surgeon will tailor the approach.

Conclusion

Pediatric fracture surgery is a carefully planned response to a broken bone that cannot heal correctly with a cast alone. It uses techniques designed around the special features of children’s growing bones: rapid healing, strong periosteum, the capacity to remodel, and the presence of active growth plates. Most operations are short, recovery is generally faster than for the same injury in an adult, and the great majority of children return to full activity.

If your child is facing fracture surgery, the most useful things you can do are simple ones: understand what the surgeon is planning and why, follow the post-operative instructions carefully, attend follow-up appointments — especially if a growth plate has been involved — and watch for the warning signs you will be briefed on. With unhurried recovery and attentive follow-up, children with even significant fractures usually go on to grow, play, and move as they did before the injury.
