Growth Plate Fractures in Children: Treatment and Recovery - Orthopedics

Growth plate fracture


A 10-year-old child was diagnosed with a growth plate fracture after being stepped on the ankle by a classmate.
The child was treated with a cast, extending up to the thigh, and it has been in place for one month and three days.
The physician recommended keeping the cast for an additional two months, followed by a rehabilitation period of six months to a year.
I would like to ask the physician: Is it common for growth plate fractures near the ankle to require a cast that extends to the thigh? What is the typical duration for wearing a cast? During the upcoming six-month to one-year rehabilitation period, is it advisable to avoid using stairs?

Dear netizens: A 10-year-old child has sustained a growth plate fracture in the ankle.
We classify fractures into six types based on severity and complexity, as well as the likelihood of complications.
Generally, ankle fractures require immobilization below the knee, but depending on the patient (child) and the severity, it may be necessary to extend the cast up to the thigh.
Continuous monitoring will then allow for the cast to be trimmed to the lower leg (which typically takes 3-4 weeks).
The timing for cast removal should be based on follow-up X-rays and the healing status of the fracture; generally, children may start to consider cast removal after 4-6 weeks.
Whether rehabilitation is needed will also depend on the healing status; typically, children do not necessarily require rehabilitation.
Wishing you good health.

Growth plate fractures, also known as physeal fractures, are common injuries in children and adolescents due to their active lifestyles and the inherent vulnerability of their developing bones. The growth plate is the area of developing tissue at the ends of long bones, and it is crucial for bone growth. When a fracture occurs in this area, it can potentially affect the child's future growth and development.

In the case of a 10-year-old child who has sustained a growth plate fracture near the ankle, the treatment typically involves immobilization with a cast. The decision to extend the cast up to the thigh, as in your child's case, depends on several factors, including the severity of the fracture, the child's age, and the specific location of the injury. In general, for ankle fractures, a cast may extend to the knee if the fracture is deemed more complex or if there is a risk of instability. This extended immobilization helps ensure that the fracture heals properly and minimizes the risk of complications.

The duration of casting can vary based on the type and severity of the fracture. Generally, for growth plate fractures, the casting period can range from 4 to 8 weeks. In your child's situation, the recommendation to keep the cast on for an additional 2 months after already being in place for over a month suggests that the physician is taking a cautious approach to ensure proper healing. After the cast is removed, rehabilitation is often necessary to restore strength and range of motion, which can take anywhere from 6 months to a year, depending on the individual case.

During the rehabilitation phase, it is crucial to follow the physician's recommendations regarding activity levels. Walking up and down stairs may be restricted initially, especially if the child is still experiencing pain or has not regained full strength and stability in the affected limb. Physical therapy may be recommended to help the child regain strength, flexibility, and coordination, which are essential for a full recovery.

In summary, growth plate fractures require careful management to ensure proper healing and to minimize the risk of long-term complications, such as growth discrepancies or joint issues. Regular follow-up appointments with a pediatric orthopedic specialist are essential to monitor the healing process and to make any necessary adjustments to the treatment plan. If there are any concerns about the healing progress or the child's ability to perform certain activities, it is important to communicate these with the healthcare provider. Early intervention and appropriate rehabilitation can significantly enhance recovery outcomes and help the child return to their normal activities safely.
