Overview
Growth plate fracture treatment is a specialised orthopaedic procedure that repairs a break in the growth plate — the soft, active layer of cartilage near the end of a child's long bone where new bone tissue is produced.
Because the growth plate is the part of the bone that controls how long and wide a bone will eventually become, a fracture there is treated differently from a break in ordinary bone. Depending on how severe the break is and which bone is affected, treatment ranges from fitting a cast or splint to hold the bone still, all the way to surgery that uses small pins, screws, or wires to realign and hold the broken pieces in the correct position while the bone heals. The goal is to protect the growth plate so that the bone continues to grow normally as the child develops.
Medical Condition
This treatment is used whenever a fracture involves or passes through the growth plate of a child or adolescent who is still growing. Growth plate fractures most commonly happen after a fall, a sports injury, or a direct impact to a limb. Because children's bones are still developing, the growth plate is actually softer and more vulnerable than the surrounding ligaments (the tough bands that connect bone to bone), making it a common site of injury.
- Fractures of the growth plate in the wrist, forearm, or hand — often caused by catching a fall
- Growth plate fractures around the knee, ankle, or foot from sports or falls
- Fractures near the shoulder or elbow following direct impact or a twisting injury
- Fractures identified as Salter-Harris type I through V — a medical classification system that describes how deeply the break involves the growth plate and the surrounding bone
- Fractures where the bone has shifted out of its normal position (displaced fractures) that require realignment
- Growth plate injuries in adolescent athletes involved in high-impact or contact sports
This treatment is generally not used in the same way for adults, because growth plates close and harden into ordinary bone once a person finishes growing — usually in the mid to late teenage years. In adults, similar injuries are treated as standard bone fractures. A doctor will review X-rays and, in some cases, an MRI (a scan that shows soft tissues clearly) to confirm whether the growth plate is involved before deciding on the right approach.
Risks & Complications
Growth plate fracture treatment is generally considered safe, but as with any injury to a developing bone, there are recognised risks that the medical team will explain to the family before treatment begins.
- Growth disturbance — the injured growth plate may slow down or stop growing, causing one limb to become shorter or differently shaped than the other; this is the most important risk specific to this type of fracture
- Bony bar formation — abnormal bone tissue can bridge across the growth plate and restrict future growth in that area
- Mal-union — the bone heals but not in perfectly straight alignment, which may affect how the limb looks or moves
- Re-fracture — the same bone breaking again before it has fully healed and strengthened
- Joint stiffness — reduced movement in the nearby joint, especially if the fracture was close to the joint surface
- Swelling, bruising, and pain around the fracture site during healing
- Infection at the skin or deeper tissues, more commonly associated with surgical treatment or open fractures (fractures where the bone breaks through the skin)
- Nerve or blood vessel injury near the fracture site, which can cause numbness, tingling, or circulation problems in the limb
- Risks related to anaesthesia (medication that prevents pain and keeps the patient still during surgery), including breathing difficulties or allergic reaction — the anaesthesia team will assess the child beforehand
- Pin or implant irritation, loosening, or migration if internal fixation (metal pins or screws placed inside the bone) has been used
Preparation & Procedure
Preparation depends on whether the treatment will be non-surgical (a cast or splint) or surgical. For non-surgical treatment, preparation is minimal. For surgery, the child and family will go through several steps in the hours or days before the procedure. The medical team will give specific instructions based on the child's age, weight, and overall health.
If surgery is planned, the child will usually be asked to stop eating and drinking for a set number of hours beforehand — this is called fasting, and it reduces the risk of complications from anaesthesia. The surgical team will tell the family exactly when fasting should begin. Any regular medications the child takes should be discussed with the doctor, who will advise which ones to continue and which to pause. Supplements and herbal remedies should also be mentioned. The family should inform the doctor of any known allergies, especially to medications, latex, or metals.
The following tests are commonly ordered before surgical treatment to make sure the child is safe to have anaesthesia and surgery:
- X-rays of the injured bone to confirm the fracture location and severity
- MRI in some cases, to see the full extent of damage to the growth plate and surrounding soft tissues
- Blood tests to check general health, clotting ability, and blood group
- A check of the child's heart and breathing, which may include an EKG (a test that records the heart's electrical activity)
On the day of the procedure, here is what typically happens in sequence:
- The child arrives at the hospital and the nursing team carries out identity checks and a health review
- A paediatric orthopaedic surgeon (a bone specialist trained to treat children) examines the limb and confirms the treatment plan with the family
- Consent forms are signed by the parent or legal guardian
- For surgery: the child is taken to the anaesthesia room, where an anaesthetist (a doctor who manages pain and sedation) gives a general anaesthetic — medication that puts the child fully to sleep so they feel nothing during the procedure
- For non-surgical treatment: the doctor carefully moves the bone back into alignment if needed — this may require a short-acting sedative to keep the child comfortable — then applies a cast or splint to hold the bone still
- For surgical treatment: small incisions (cuts) are made near the fracture site; the surgeon uses X-ray guidance on a screen in real time to position pins, screws, or wires precisely across the fracture to hold the bone in the correct place
- The wound is closed with stitches, and a cast or splint is usually applied over the operated area
- The child is moved to a recovery room to wake up safely from anaesthesia before going to the ward or being discharged
Aftercare
After treatment, the child's recovery is closely monitored by the medical team. For non-surgical cases, most children go home the same day once the cast is in place and comfort is confirmed. After surgery, the child usually stays in hospital for observation, and the length of stay depends on the type of surgery, the bone involved, and how the child is feeling. Pain is managed with appropriate medications prescribed by the team. Full recovery time varies — simpler fractures in younger children can heal within a few weeks, while more complex fractures involving surgical fixation may take several months before the child returns to full activity.
- Cast or splint care: the family will be taught how to keep the cast dry and check for warning signs such as increased pain, swelling, numbness, or skin colour changes under the cast — these should be reported to the medical team promptly
- Activity restrictions: the child will be advised to avoid putting weight on the injured limb and to stay away from sports and vigorous play for a period that the doctor will specify
- Pin care: if pins are left sticking out through the skin temporarily, the family will receive instructions on keeping the pin sites clean to prevent infection
- Follow-up X-rays: the doctor will schedule repeat X-rays at regular intervals — usually several times over the coming weeks and months — to check that the bone is healing correctly and that the growth plate is not being disturbed
- Pin or implant removal: in many cases, pins or wires are removed under a short anaesthetic once the bone has healed sufficiently; screws may sometimes be left in place long-term
- Physiotherapy (guided exercises to restore movement and strength): this is recommended for some children, especially after fractures near a joint or after longer periods of immobilisation
- Long-term growth monitoring: the treating doctor will usually want to follow up with the child for a year or more after the injury, because growth disturbances can sometimes appear months after healing, particularly during growth spurts
- School and daily life: many children can return to school relatively quickly, but activities involving the injured limb will be gradually reintroduced based on healing progress
- Nutrition: a diet that supports bone healing — including adequate calcium and vitamin D from food sources — is generally encouraged; the doctor or a dietitian can advise the family
Frequently Asked Questions
How many treatment sessions or visits will my child need for a growth plate fracture?
The number of visits depends on how serious the fracture is and which bone is affected. A minor fracture managed with a cast may need only a handful of follow-up check-ups over several weeks, while a more complex fracture that requires surgery will involve additional visits for wound checks, cast or splint changes, and physiotherapy sessions. Your child's orthopaedic doctor will outline a schedule after seeing the injury on imaging.
What does growth plate fracture treatment feel like for a child — is it painful?
The level of discomfort varies with the type of treatment. A cast or splint fitting is generally not painful once the initial injury pain is managed with appropriate pain relief. If surgery is needed, your child will be under general anaesthesia — meaning they will be fully asleep and feel nothing during the procedure — though some soreness around the site is normal in the days afterwards and is usually managed with prescribed pain relief.
How soon will my child start to feel better and return to normal activity?
Most children begin to feel noticeable improvement within the first few weeks as swelling goes down and the bone starts to heal. Returning to sports or vigorous play usually takes several weeks to a few months, depending on which growth plate — the soft area near the end of a growing bone where new bone forms — was injured and how it was treated. Your doctor will use follow-up X-rays to decide when it is safe to increase activity.
What warning signs should I watch for while my child is recovering?
Contact your child's doctor promptly if you notice increasing pain, swelling, or redness around the injured area, a fever, numbness or tingling in the limb, fingers or toes that look pale, blue, or feel cold, or if a cast feels too tight. These could indicate complications such as poor circulation or infection that need to be assessed quickly. Regular follow-up appointments are also important because growth plate injuries can sometimes affect how the bone grows over time, and early detection allows doctors to manage any changes.
