Abstract

Flatfoot with hindfoot valgus is a common problem in neurological patients. It characterized by the loss of the longitudinal arch, pain, ulceration and dermal plantar hyperkeratosis, shortening of the Achilles tendon and failure in the use of orthoses. The objective of our job is to show the results of the neurological flatfoot treatment with calcaneal lengthening using Bone Substitute graft (Pro-Dense®). Material and methods: A retrospective study was carried out in which we included all patients who underwent surgery for neurological symptomatic flatfoot. Measures were made of the Talo-Calcaneal angle, Talo-1MT y Calcaneal Pitch. It has been also analyze the postoperative clinic results. Results: 17 patients (27 feet). Astragalus-Calcaneo angle preoperative 26.07° and postoperative de 21.22°. Talo-1MT angle 27.04° preoperative y 13.22° postoperative. Calcaneal Pitch preoperative angle 12.63° and postoperative 21.37°. It was observed a statistically significative change. In all cases we obtain painless feet, with the disappearance of the plantar hyperkeratosis, correction of the hindfoot valgus and longitudinal arch formation. Conclusions: The calcaneal lengthening with Bone Substitute graft technique is an alternative for the Neurological flatfoot treatment. With good results, corrections of the angular deformities and low rate of complications.
