What is the typical imaging and follow-up approach for a nondisplaced tibial fracture in a child?

• A. Immobilization with a long-leg cast and close follow-up
• B. Surgical fixation
• C. Short leg cast and no follow-up
• D. Physical therapy only

Answer: (A)

In children, nondisplaced tibial fractures heal well with nonoperative care, so stabilization and close monitoring are the approach. Start with plain radiographs to confirm the fracture is truly nondisplaced and to guide immobilization. A long-leg cast is used to immobilize the knee and ankle, reducing movement that could cause displacement and providing solid stabilization during healing.

Follow-up relies on serial imaging to ensure the alignment remains intact as healing progresses. Casts are typically worn for several weeks (often around 4–6, depending on age and fracture pattern), with radiographs obtained at intervals to document healing before removing the cast. After removal, gradual return to activity and, if needed, a short period of physical therapy help restore range of motion and strength.

Surgical fixation isn’t usually needed for a nondisplaced fracture in a child because the healing potential is high and stabilization with a cast is effective. A short leg cast with no follow-up wouldn’t provide enough control to confirm continued alignment, and relying on physical therapy alone wouldn’t stabilize the fracture during healing.
