Extra-osseous talotarsal stabilisation device for a flail-deformed foot

Area of Science:

• Pediatric Orthopaedics
• Foot and Ankle Surgery
• Biomechanical Engineering

Background:

• Flail plano-valgus foot with tendo-achilles contracture presents a significant challenge in pediatric orthopaedics.
• Conservative treatments are often insufficient for severe cases, necessitating surgical intervention.

Purpose of the Study:

• To evaluate the efficacy of extra-osseous talotarsal stabilization device insertion combined with tendo-achilles lengthening for treating pediatric flail plano-valgus foot.
• To report on the surgical outcomes and functional recovery in a young patient.

Main Methods:

• A case study detailing the surgical procedure for a young boy diagnosed with flail left plano-valgus foot and tendo-achilles contracture.
• Inclusion of an extra-osseous talotarsal stabilization device into the subtalar joint and tendo-achilles lengthening.
• Post-operative immobilization with a below-knee plaster of Paris slab for 3 weeks.

Main Results:

• The surgical procedure was performed without intraoperative or postoperative complications.
• The patient achieved a plantigrade foot, enabling normal ambulation.
• Successful correction of the complex foot deformity was observed.

Conclusions:

• Extra-osseous talotarsal stabilization device insertion with tendo-achilles lengthening is an effective surgical option for pediatric flail plano-valgus foot.
• This approach offers a viable solution for complex foot deformities, leading to improved functional outcomes.
• Orthopaedic surgeons should consider innovative surgical techniques for challenging pediatric cases.
