Growth Plate Injuries in Children: Prevention and Rehabilitation

Growth plate injuries are common in children and teenagers, especially those who play sports. Unlike adults, children have soft areas of growing tissue near the ends of their long bones. These areas, called growth plates, are vulnerable to injury. When hurt, they need prompt and proper care. Understanding how to prevent these injuries and how to support recovery can protect your child's long-term bone health and development.

What's a Growth Plate and Why Does it Matter?

Growth plates are areas of soft cartilage near the ends of your child's long bones, in their arms, legs, hands, and feet. Think of them as the "factories" where new bone is made. As your child grows, these plates produce new bone tissue, lengthening their bones year after year.

Growth plates are softer than regular bone; they are weaker. An injury that might just sprain your ankle could fracture your child's growth plate.

About one in three childhood fractures involves a growth plate, which is a significant number. These injuries are most common in boys between the ages of 14 and 16, but they can also occur in younger children. Girls typically stop experiencing growth plate injuries around age 14-15 because their bones mature earlier.

How Do These Injuries Happen?

There are two ways in which a paediatric growth plate fracture can happen :

​

Sudden injury: Sudden injuries—such as falling off a bike, getting tackled during football, or having an accident—are the most common cause of growth plate fractures. The force from these incidents can break the growth plate.

​

Overuse: Sometimes fractures develop slowly from repeated use of the same motion. This happens with young athletes who train intensely, cricketers who bowl for hours, gymnasts who practice daily, and runners who overtrain. In today's competitive sports culture, where children attend after-school coaching and training classes, overuse injuries are becoming increasingly common. The most common places for growth plate fractures are the wrist, ankle, knee, and fingers. Of particular concern are the growth plates in the knee and thigh, as they are more likely to affect future growth.

How Can You Tell if Your Child Has a Growth Plate Injury?

Pain: Not the kind that comes and goes and is easily dismissed, but real pain that does not subside.

Swelling and tenderness: The area is swollen and tender to the touch.

Can't use the limb: Your child refuses to put weight on the injured limb.

Looks wrong: The limb may look bent in an unusual way, shorter than usual, or deformed.

Limited movement: The child is unable to move the joint normally.

Don't assume it is just a bad sprain. What looks like a sprain may very well be a growth plate injury in children. Get it checked.

Getting the Right Diagnosis

At the hospital, the doctor will ask how the injury happened, examine your child, and order X-rays. Growth plates don't show up clearly on X-rays because they are cartilage, not a bone. They appear as gaps between the bone shaft and the bone end. Sometimes fractures through growth plates are hard to see. If the doctor suspects a growth plate injury, they might order an MRI or CT scan to better visualise the soft tissue. These tests help doctors diagnose the kind of fracture and treat it accordingly.

Types and Severity

There are five types of growth plate fractures according to the Salter-Harris classification system. Type I and Type II are the most commonly occurring types of fractures and have better healing outcomes. Types III, IV, and V are rarer but more serious as they are more likely to affect future bone growth. You don't need to memorise these types. What you need to know is that your child's doctor will determine the severity and plan treatment accordingly.

Growth Plate Fracture Treatment

• For simpler fractures (most common): The child will receive a cast or splint to immobilise the bone while it heals. The cast may need to remain in place for 4 to 8 weeks. During this period, running, sports, and physical play should be avoided. While this can be challenging for active children, proper healing requires patience and adherence to the recommended rest period.
• If the bones are out of position: The doctor needs to "set" them back into place. This is called reduction.
• Closed reduction: The doctor uses their hands to realign the bones after administering adequate pain medication to your child. No cuts are needed in case of closed reduction.
• Open reduction: For more serious fractures, your child needs surgery. The doctor makes an incision, realigns the bones, and uses pins, screws, or plates to hold them in place. After surgery, a cast is applied to protect the area whilst it heals.

Rehabilitation After Growth Plate Fracture

Once the bone heals, your child cannot just jump back into sports. Rehabilitation after a growth plate fracture is important.

Physical therapy: Your child will work with a physiotherapist to:

• Regain the full range of motion in the joint.
• Rebuild muscle strength, as affected muscles weaken when unused.
• Improve balance and coordination.
• Learn safe ways to move to prevent re-injury

Timeline: Don't rush. Even after the cast comes off, it takes weeks to months to fully recover. Pushing too hard, too soon, can cause re-injury.

Returning to sports: Your doctor will tell you when it's safe to resume sports. Usually, your child needs medical clearance before returning to cricket, football, basketball, or any contact sport.

Will This Affect Your Child's Growth?

This is what worries every parent most.

The truth? Most growth plate fractures heal completely with no long-term problems. However, in cases of severe injury or delayed treatment, the growth plate may close prematurely. This might cause:

• One limb is shorter than the other.
• A bone that grows crooked.
• A joint that doesn't line up properly.

This is why follow-up appointments are so important. Your doctor will monitor your child's bone growth for months or even years after the injury to catch any problems early. If growth problems develop, additional treatment, sometimes surgery, may be needed to fix them.

Preventing Growth Plate Injuries

You can't prevent every injury, but you can reduce its risk:

Use safety gear: Helmets, knee pads, elbow pads, wrist guards. Yes, even when playing in your neighbourhood. Because falls happen.

Avoid overuse: If your child plays sports, be sure they:

• Take breaks between seasons.
• Don’t use the same body part every single day.
• Listen to their body when it hurts.
• Take at least one rest day per week away from sports activities.

Build strength: Encourage your child to participate in a variety of activities that build both muscle and bone strength, rather than focusing on a single sport.

Proper technique: Make sure your child uses proper technique in their sport. The wrong technique will put unnecessary stress on bones and joints.

Know when to stop: If your child complains of persistent pain, don't tell them to "tough it out." Listen to them. Pain is a warning sign.

Conclusion

Growth plate injuries in children are serious, yet preventable conditions. Proper warm-ups, use of protective gear, and avoiding overtraining can greatly reduce the chances of growth plate injuries. Should the child sustain such an injury, appropriate and timely medical care and rehabilitation can lead to full recovery and even stronger and healthier children.
