Midfoot Fusion Surgery

Midfoot fusion surgery is indicated for patients with symptomatic midfoot arthritis, or as part of deformity correction such as flatfoot corrective surgery or hallux valgus correction.

This surgery involves two incisions, one on the inside of the foot (medial) and one on the top of the foot (dorsal), exposing the midfoot joints and preparing them for fusion. The joints are then compressed with screws, plates and/or staples to hold them rigid whilst fusion occurs

Success rates: 80-85% of patients are satisfied with the procedure and have improvement of symptoms

 

Post-operative plan:

  • Surgery is 1-2 nights in hospital.

  • A nerve block is administered to help with post-operative pain

  • 0-2 weeks: elevation at home to reduce swelling in a plaster cast

  • 2-6 weeks: transition to a CAMboot with arch support, start range of motion exercises but remain non weight bearing

  • 6-10 weeks: start walking in the CAMboot then gradually wean out of this over the four week period.

  • 12 weeks onwards: return to walking in comfortable shoes. Swelling will often be present for up to 6 months.
