    Summary
    This summary is machine-generated.

    Pollicisation surgery, which reconstructs a thumb using the index finger, significantly improves hand function in children with congenital thumb differences. Early surgical intervention leads to better long-term outcomes and hand use.

    Area of Science:

    • Hand surgery
    • Pediatric orthopedics
    • Congenital abnormalities

    Background:

    • Congenital aplasia or hypoplasia of the thumb presents a significant functional challenge for affected children.
    • Restoring thumb function is crucial for overall hand dexterity and daily activities.

    Purpose of the Study:

    • To evaluate the long-term functional outcomes of pollicisation surgery in children with congenital thumb aplasia/hypoplasia.
    • To determine the effectiveness of index finger pollicisation in improving hand function.

    Main Methods:

    • A cohort of nine children with congenital thumb aplasia or hypoplasia underwent index finger pollicisation.
    • Functional assessments, including sensation and grip strength (power, pinch, adductor), were performed approximately five years post-surgery.

  • Comparison was made with the unoperated contralateral hand.

    • Main Results:

    • Post-surgery, patients demonstrated normal sensation in the reconstructed thumb.
    • Achieved grip strengths were 63% (power grip), 56% (pinch grip), and 63% (adductor grip) relative to the unoperated hand.
    • Efficient hand use showed improvement after surgery, with continued gains observed over subsequent years.

    Conclusions:

    • Index finger pollicisation is an effective surgical procedure for improving hand function in children with congenital thumb aplasia or hypoplasia.
    • Early surgical intervention is recommended to maximize functional benefits and long-term hand use.
