Fractures in children can be particularly concerning for parents, especially when terms like "greenstick" and "growth plate" fractures are involved. These two types of fractures differ quite a bit in their causes, how they impact the bone, and treatment approaches. At Miller Children's and Women’s Hospital in Long Beach, we have extensive experience in diagnosing and treating both types of children's bone fractures. Here is what parents need to know to ensure the best possible care for your child.
What Are Greenstick Fractures?
Greenstick fractures occur when a child’s bone bends and partially breaks, rather than snapping completely. These fractures are unique to children due to their soft, flexible bones, which are still developing. The term "greenstick" helps describe the fracture, which is similar to the way a young green twig bends and breaks only partially when force is applied.
Common Causes of Greenstick Fractures Include:
- Falls or accidents, such as falling off a bike or playground equipment.
- Direct trauma to a limb, often during sports activities or play.
Symptoms and Diagnosis of a Greenstick Fracture
Signs of a greenstick fracture include swelling, tenderness, and a visible deformity or bend in the affected limb. While the child may be able to move the limb slightly, persistent pain is a tell-tale sign. Diagnosis is usually confirmed through X-rays, which reveal the partial break and bending.
Treatment of a Greenstick Fracture
Treatment for greenstick fractures is relatively straightforward. The primary goal is to realign the bone and immobilize it for proper healing. This can be done through:
- Splinting or casting: The limb is immobilized to ensure the bone heals in the acceptable position.
- Realignment: In more severe cases, a healthcare provider may manually realign the bone.
Recovery is generally quick, as children’s bones heal faster than an adult’s bones. Physical therapy may be recommended for severe cases to restore your child’s full functionality.
What Are Growth Plate Fractures?
Growth plate fractures affect the areas of cartilage located at the ends of long bones in children. These growth plates are essential for determining the future length and shape of the bone.The growth plate is often affected because the cartilage is not quite as strong as the bone around it, so it fails first. A growth plate fracture can potentially disrupt normal growth, which is why prompt and careful treatment is important.
Common Causes of Growth Plate Fractures Include:
- Injuries that are often caused by regular fractures such as falls, car accidents, or sports-related trauma.
- Overuse, especially in young athletes involved in repetitive activities like running or pitching.
Symptoms and Diagnosis of Growth Plate Fractures Include:
- Severe pain and tenderness in and around the growth plate area (commonly at the wrist, ankle, or knee).
- Swelling and difficulty moving the injured limb.
Unlike greenstick fractures, growth plate fractures may not be immediately visible on X-rays. Advanced imaging techniques such as MRI or CT scans might be necessary for accurate diagnosis.
Treatment of Growth Plate Fractures
Treatment will depend on the severity of your child's condition:
- Immobilization: Splinting or casting is often sufficient for less severe fractures.
- Realignment: In more severe cases, a healthcare provider may manually realign the bone.
- Surgical intervention: For complex or displaced fractures, surgery may be required to properly align the growth plate. Pediatric orthopedic surgeons specialize in these types of surgeries.
Follow-up care is essential to monitor bone development and ensure that normal growth resumes.
Key Differences Between Greenstick and Growth Plate Fractures
While both types of fractures are common in children, their differences relate to the following:
- Location: Greenstick fractures occur along the shaft of a bone, while growth plate fractures affect the ends of bones where cartilage is present.
- Impact on Growth: Growth plate fractures have a higher risk of affecting bone development, whereas greenstick fractures never impact growth.
- Treatment Complexity: Growth plate fractures may require more advanced interventions, including surgery, compared to greenstick fractures.
Advances in Diagnosis and Treatment of Bone Fractures in Children
Recent studies and technological innovations have significantly improved outcomes for children with fractures. Pediatric orthopedic surgeons are specialists in treating musculoskeletal conditions in children. They may recommend any of the following tests and treatments below in caring for your child:
- Imaging Technology: High-resolution imaging methods like 3D MRI allow for precise assessment of growth plate injuries, ensuring accurate treatment.
- Surgery: Immediate surgery may be recommended to address the fracture itself, or future surgery to address any growth disturbances that could potentially occur.
- Rehabilitation Techniques: Specialized physical therapy programs tailored to children help restore mobility and minimize complications.
Research continues to evolve, with a focus on minimizing long-term effects on growth and functionality.
When to See a Specialist
Both greenstick and growth plate fractures can be treated with timely intervention by a qualified pediatric orthopedic specialist at Miller Children’s. Early diagnosis, appropriate treatment, and consistent follow-up are critical for ensuring your child’s recovery and long-term well-being. If you suspect your child has a fracture, contact our Pediatric Orthopedic Center. As a parent, staying diligent and informed about these conditions empowers you to make the best decisions for your child’s health when faced with a fracture.
Bio
Emory Chang, M.D., is a pediatric board-certified orthopedic surgeon at the Orthopedic Center at Miller Children's & Women's Hospital in Long Beach. He specializes in the correction of congenital and acquired spinal or limb deformities as well as pediatric orthopedic trauma.
Dr. Chang earned his undergraduate degree in Molecular Biology at the University of California at Berkeley and his medical degree from the University of California at San Diego. Dr. Chang then went on to complete his general orthopedic residency training at the University of Southern California. He went on to complete his pediatric orthopedic fellowship at Children's Hospital of Los Angeles. Since completing his specialty training, Dr. Chang has pursued further sub-specialty training in limb lengthening and reconstruction as well as the Ponseti method of non-operative clubfoot management. He is a member of the Pediatric Orthopaedic Society of North America (POSNA) and has consulted on the development of several pediatric-specific implants for use in the spine and extremities.
