Subtalar Arthrodesis for Posterior Tibial Tendon Dysfunction and Pes Planus

Arthrodesis Techniques in the Management of Stage-Ii and Iii Acquired Adult Flatfoot Deformity

“…There is support in the literature for the use of isolated subtalar arthrodesis to treat acquired adult flatfoot deformity when the patient has a fixed deformity of the subtalar joint and a flexible forefoot 22,23 . Mann et al stated that 10° to 15° of forefoot varus or joint hypermobility is a contraindication to isolated subtalar joint fusion 10 .…”

“…The procedure allows residual motion at the talonavicular and calcaneocuboid joints (26% and 56% residual motion, respectively 8 ). This may have a protective effect on the development of ankle arthritis when compared with triple arthrodesis 23 . However, the authors of an in vitro biomechanical study concluded that isolated subtalar or calcaneocuboid fusion cannot achieve full correction of a moderate flatfoot deformity with substantial transverse tarsal joint laxity; in contrast, a talonavicular, double, or triple arthrodesis completely corrected the deformity 24 .…”

“…At two years postoperatively, the results compared favorably with those of medial displacement calcaneal osteotomy and lateral column lengthening. Kitaoka and Patzer reported sixteen good or excellent results at three years following subtalar joint realignment and arthrodesis in twentyone feet 23 . Complications included symptomatic arthrosis of adjacent joints, malunion, and nonunion.…”

In vivo three-dimensional analysis of hindfoot kinematics in stage II PTTD flatfoot

“…Results Compared with normal participants, with the calcaneus relative to the talus, participants with stage II PTTD flatfoot presented more dorsiflexion (p < 0.05), adduction (p < 0.05), and eversion (p < 0.05) in rotation, and more anterior (p < 0.05) and distal translation (p < 0.05) from maximal plantarflexion to maximal dorsiflexion; more for more than two decades. The effects of various operations to correct PTTD flatfoot deformity have been reported in most of the clinical investigations [4]. A combination of bony and soft-tissue procedures was usually involved in the operative management.…”

Individual variability of morphometric parameters feet of girls 18-19 years from Saratov region of the Russian Federation

“…The foot is a spring unit for easy walking, determining its smooth, absorbing swing and body vibrations [3]. Standing daily constant physical activity of different duration and intensity, the foot reacts with the active resistance to preserve its anatomical integrity and biomechanical functionality [4,5].…”
