[Acquired flat foot of the adult by posterior tibial dysfunction. Options for surgical treatment].

We present the possible etiopatogenic causes of posterior tibial dysfunction or painful flat foot of the adult and the cause-and-effect relationship that may exist. We also expose the gradation of the lesion and the different therapeutic options for the surgical treatment of the deformity. Since 1939, multiple articles have been published, which have been endorsed by clinical, experimental, electromyographic and biomechanical studies; publications that have been consulted and evaluated for the development of this review.

[Disruption of anterointernal weight bearing: sequelae of surgical treatment of hallux valgus].

Sequelae of forefoot surgery range between 30 and 40%; the most frequent ones are transfer metatarsalgia and deformity relapse. Forefoot surgery complications disrupt biomechanics. Anterointernal weight bearing alteration is most frequent, due to involvement of the metatarsal, the phalanx or both.

Comparative study of the Weil osteotomy with and without fixation.

Background: Weil osteotomy is a technique widely used in patients with metatarsalgia which shortens the metatarsal and reduces the load under the metatarsal head.

Methods: The aim of this paper is to compare the results of the Weil osteotomy with and without any fixation system. We present a retrospective study of 92 patients (97 feet) who underwent treatment for metatarsalgia between 1999 and 2005.
