Endoscopic assisted flexor digitorum longus transfer in flexible flatfoot

Posterior tibial tendon insufficiency is the commonest cause of adult flexible flatfoot. Transfer of the flexor digitorum longus (FDL) has been described a therapeutic arsenal in flexible flat feet and posterior tibial tendon disorders. It is often combined with bony procedure (open or percutaneous calcaneal osteotomy). We describe a technique and the steps endoscopic approach of FDL transfer. The procedure is able to be performed safely and reproducible under perfect viewing In the future with a clinical study investigating, we purpose the results of such surgery in a cohort of patients with flexible flatfoot. Level IV Therapeutic study: case serie. No funding was received for this research project.
