The effect of flatfoot deformity and tendon loading on the work of friction measured in the posterior tibial tendon.
BACKGROUND There is limited information regarding the mechanical factors contributing to the progression of posterior tibial tendon dysfunction. Therefore, an investigation of the mechanical forces on the posterior tibial tendon may improve our understanding of this pathology. METHODS The gliding resistance and excursion of the posterior tibial tendon in the retromalleolar region was measured...
متن کاملPosterior Tibial Tendon Dysfunction: An Overview
BACKGROUND Adult acquired flatfoot deformity is a commonly seen condition with a large clinical spectrum. It ranges from asymptomatic subjects to severely disabled arthritic patients. Posterior tibialis tendon dysfunction is a common cause of adult acquired flatfoot deformity. METHODS This article systematically reviews the published literature from books and journals that were either origina...
متن کاملAnatomy, pathophysiology and classification of posterior tibial tendon dysfunction.
OBJECTIVE Adult acquired flatfoot deformity is generally associated with a collapsing medial longitudinal arch and a progressive loss of strength of the posterior tibial tendon (PTT). This condition is commonly associated with PTT dysfunction or rupture, which can have an arthritic or a traumatic etiology. Several causes have been proposed to explain the clinical evidence of tendon degeneration...

Acquired flatfoot deformity caused by dysfunction of the posterior tibial tendon is a common clinical problem. Treatment, which depends on the severity of the symptoms and the stage of the disease, includes nonoperative options, such as rest, administration of antiinflammatory medication, and immobilization, as well as operative options, such as tendon transfer, calcaneal osteotomy, and several...
متن کاملHallux valgus, ankle osteoarthrosis and adult acquired flatfoot deformity: a review of three common foot and ankle pathologies and their treatments
The pathogenesis of hallux valgus deformity is multifactorial. Conservative treatment can alleviate pain but is unable to correct the deformity. Surgical treatment must be adapted to the type and severity of the deformity. Success of surgical treatment ranges from 80% to 95%, and complication rates range from 10% to 30%.Ankle osteoarthrosis most commonly occurs as a consequence of trauma. Ankle...
