Hindfoot instability in cavovarus deformity: static and dynamic balancing. In addition to the hereditary factor, overpronation and flat feet can also can be caused by pregnancy, obesity, and repetitive activities such as running. Ligaments and tendons in the hindfoot connect the rear parts of the foot to other parts of the foot or leg (as is the case with the Achilles tendon), aid movement, and contribute to balance and stability. A schwannoma (arrows) is identified within the tarsal tunnel on (4a) T1 weighted sagittal and (4b) fat-suppressed T2 weighted axial images. Deformity correction includes release of soft tissue contractures, osteotomies and arthrodeses, and tenotomies or tendon transfers to balance muscle strength and prevent recurrence. Arunakul M, Amendola A, Gao Y, Goetz JE, Femino JE, Phisitkul P. Foot Ankle Int. Unlike other x-ray blood irradiators, the RS 3400 is completely self-contained and requires no external water supplyfor tube cooling. Because of their location in the heel area, the various components of the hindfoot affectand are affected bythe rest of the foot and the lower leg. Three examiners measured the radiographic indices at two sessions, and intraobserver and interobserver reliability was determined. Among 35 congenital club feet (talipes equinovarus), treated following the surgical technique described by Codivilla (13 feet) and by Turco (22 feet), 11 had serious secondary valgus of the hindfoot, which gave the foot an appearance similar to a flat foot. The Achilles tendon runs down the back of the leg and attaches the calf muscle to the calcaneus. Surgical correction of osseous lateral hindfoot impingement related to hindfoot valgus is increasingly being performed .
