Tibialis Posterior Reconstruction for pes planus
Subscribe to get full access to this operation and the extensive Foot Surgery Atlas.
The operation described using a Flexor Digitorum Longus(FDL) transfer , Spring ligament plication and medialising Calcaneal osteotomy is the classic reconstruction for a grade 2 (flexible ) flat foot due to Tibialis Posterior dysfunction.
Tibialis Posterior dysfunction is typically a condition of middle age and onwards in which conservative management with Orthotics and physiotherapy is usually the first line of management and often successful.
Surgical correction of the flexible flat foot using the FDL transfer with Calcaneal osteotomy (and other procedures) results in high patient satisfaction rates and symptomatic relief but with a slightly lower incidence of maintained correction of the pes planus deformity.
