This study presents a modified Chopart

Area of Science:

  • Pediatric Orthopedics
  • Surgical Innovation
  • Limb Amputation

Background:

  • Traditional Chopart's amputation can lead to complications like plantar flexion and skin breakdown.
  • Existing amputation techniques pose challenges for pediatric patients with congenital foot malformations.

Purpose of the Study:

  • To introduce and evaluate a modified Chopart's amputation technique.
  • To address and mitigate the known complications of traditional Chopart's amputation in children.

Main Methods:

  • A novel surgical approach involving contouring of tarsal bones (talus and calcaneus).
  • Tendons (tibialis anterior/posterior, extensor digitorum longus, extensor hallucis longus) were transferred to the talar neck and sustentaculum tali.
  • Anterior advancement of the plantar flap and lengthening of the tendo Achillis were performed.

Main Results:

  • The modified procedure was prospectively performed on eight feet in six pediatric patients.
  • Follow-up averaged 3.5 years with no reported complications.
  • The technique demonstrated functional utility and safety in the study cohort.

Conclusions:

  • The modified Chopart's amputation is a viable and effective surgical option for children.
  • This technique successfully overcomes the limitations of traditional Chopart's amputation.
  • It offers a functional solution for pediatric foot ablation due to congenital anomalies.
