    Surgical Techniques

    Plantar Fascia Release and Soft Tissue Procedures

    Release of the tight plantar fascia and other soft tissue structures contributing to the deformity. Often includes tendon transfers for muscle rebalancing.

    When it is used

    Flexible cavus foot with symptoms not responding to orthotics and physical therapy.

    Recovery

    Cast or boot for 4-6 weeks. Custom orthotics long-term.

    Calcaneal Osteotomy (Dwyer)

    Correction of hindfoot varus through a wedge osteotomy of the calcaneus to restore proper alignment.

    When it is used

    Rigid hindfoot varus component of cavus deformity.

    Recovery

    Non-weight bearing cast for 6 weeks. Progressive weight bearing. Full recovery 3-4 months.

    First Metatarsal Dorsiflexion Osteotomy

    Elevation of the first metatarsal to reduce forefoot equinus and improve weight distribution.

    When it is used

    Plantarflexed first ray contributing to cavus posture.

    Recovery

    Cast or boot for 4-6 weeks. Weight bearing as tolerated.

    Postoperative Overview

    Cavus foot correction often requires multiple procedures addressing different components of the deformity. A thorough neurological evaluation is essential before surgery to identify any underlying cause (Charcot-Marie-Tooth, etc.).

    Recovery Pathway (indicative)

    Note: This is an indicative pathway, personalised after surgery. Some elements are relatively stable (goal of the procedure, approximate hospital stay, presence of a cast or brace); others depend on the individual case (weight bearing, range of motion, imaging, sport, hardware removal, follow-up intervals) and on the surgical technique chosen.

    1. Hospital stay

      Day-surgery to 1 night depending on procedure complexity.

    2. First weeks

      Weeks 1-6: Cast or walking boot. Non-weight bearing to progressive weight bearing based on specific procedures.

    3. Second month

      Weeks 6-8: Transition to supportive footwear with custom orthotics. Begin physical therapy.

    4. Third month

      Months 2-4: Progressive strengthening and balance exercises. Orthotics adjusted as needed.

    5. Return to sport

      Return to sport: 3-4 months. Ankle stability exercises important. Custom orthotics for sports.

    6. Follow-up

      Follow-ups at 2 weeks, 6 weeks, 3 months, 6 months, 1 year. Long-term if neurological condition present.

    Possible Complications

    Undercorrection/overcorrection, recurrence (especially if neurological cause), wound healing issues, ankle instability.
