Forefoot abduct shoes combined with orthopedic shoes (FAS+OS) effectively correct moderate congenital talipes equinovarus (CTEV) deformities, particularly forefoot adduction, in children. This combined approach shows improved outcomes compared to traditional methods.
Area of Science:
- Orthopedics and Biomechanics
- Pediatric Podiatry
- Medical Device Engineering
Background:
- Congenital talipes equinovarus (CTEV) presents with equinus, varus, cavus, and adduction deformities.
- Forefoot adduction is a persistent challenge in CTEV treatment, often inadequately addressed by existing methods.
- Moderate CTEV deformities in walking-age children require effective corrective strategies for optimal outcomes.
Purpose of the Study:
- To develop and evaluate a novel corrective method for reducing forefoot adduction in moderate CTEV.
- To compare the effectiveness of forefoot abduct shoes with orthopedic shoes (FAS+OS) against traditional treatments.
- To assess the impact of different orthotic interventions on foot morphology and plantar pressure distribution.
Main Methods:
- A comparative study involving 53 children with moderate CTEV, categorized by Diméglio classification.
- Interventions included Dennis Brown (DB) splint, DB splint with orthopedic shoes (DB+OS), and FAS+OS.
- 3D scanning and pedobarography analyzed morphological characteristics and plantar pressure; data analyzed using MAVONA.
Main Results:
- The FAS+OS group demonstrated significantly improved bimalleolar angle and reduced bean-shape ratio compared to DB and DB+OS groups.
- Both DB+OS and FAS+OS groups showed higher heel/forefoot and heel/LMF pressure ratios than the DB group.
- FAS+OS proved critical for correcting forefoot adduction, while OS addressed equinus and varus components effectively.
Conclusions:
- Forefoot abduct shoes are essential for correcting forefoot adduction in moderate CTEV.
- Orthopedic shoes play a vital role in correcting equinus and varus deformities in CTEV.
- The combination of FAS+OS offers improved treatment outcomes for children with moderate CTEV, especially those without severe torsional deformities.
