    Immobilization in children with femur fractures affects calcium excretion. Older children showed increased calcium excretion with Kirschner wire treatment, while younger children had decreased excretion with traction.

    Area of Science:

    • Pediatric orthopedics
    • Pediatric nephrology
    • Bone metabolism

    Background:

    • Investigating calcium excretion in pediatric patients immobilized due to femur fractures.
    • Assessing the impact of different immobilization methods on calcium balance.

    Observation:

    • Studied 31 children with femur fractures under immobilization.
    • Compared calcium excretion between age groups and treatment methods (Kirschner wire vs. overhead traction).

    Findings:

    • Children over 5 treated with Kirschner wire extension showed significantly increased calcium excretion, which normalized post-mobilization.
    • Younger patients treated with overhead traction exhibited decreased calcium excretion.
    • Calcium Excretion Quotient (CEQ) using early morning urine and specific gravity was employed to assess hypercalcemia.

    Implications:

    • The study suggests that specific immobilization techniques influence calcium excretion differently in pediatric femur fractures.
    • Findings indicate that routine dietary or drug interventions for hypercalcemia may not be necessary in these cases.
    • Highlights the importance of considering age and treatment modality in managing calcium balance during pediatric fracture immobilization.
