Seven species of the genus Triomicrus Sharp are recognized in southern China, six of them are described as new: T. acutus  and T. nanlingensis Shen & Yin, sp. n. (Guangdong), T. pinnatus Shen & Yin, sp. n. (Guangdong and Hunan), T. cochlis Shen & Yin, sp. n. (Guangdong, Hunan and Guangxi), and T. cavus Shen & Yin, sp. n. and T. longus Shen & Yin, sp. n. (Guangxi). A key for the identification o...

Changes in foot and ankle posture are a normal aspect of infant and child development but may also reflect neurological conditions affecting the brain, spinal cord, peripheral nerves or muscles. Development of cavus or planus foot deformities often reflects underlying neurologic disorders and may predate development of more overt neurological signs. This session will concentrate upon signs and ...

A 99-year-old Chinese woman presented to our emergency department after a fall. Due to lower extremity pain, radiographs of both feet were obtained. No fractures were noted, but these images did reveal prominent pes cavus deformities and foreshortening of the feet, consistent with foot binding as a child. The radiographic findings associated with foot binding are described and other associated ...

Introduction Congenital talipes equinovarus (CTEV) is a deformity in which the foot is in structural equinus, varus, adductus and cavus and occurs in approximately 1 per 1000 births [1]. Despite good initial correction with the Ponseti technique, a tibialis anterior tendon transfer (TATT) is required in 20-25% of cases to correct residual dynamic supination observed during gait. Currently, no r...

Background People who have extremely high-arched feet or pes cavus often suffer from substantial foot pain. Custommade foot orthoses have been shown to be an effective treatment option, but their specificity is unclear. It is generally thought that one of the primary functions of custom foot orthoses is redistribution of abnormal plantar pressures. This study sought to identify variables associ...

The allelic disorders rapid-onset dystonia-parkinsonism (RDP), alternating hemiplegia of childhood (AHC), and CAPOS/CAOS syndrome (cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural deafness) are caused by ATP1A3 mutations. Intermediate RDP-AHC phenotypes are emerging. Positional mutations 274, 583, 867, and 923 lead to both RDP and AHC, suggesting different pathomechanis...
