A popular term for an ear deformity, morphologically likened to a dial telephone handset, which is an undesired result of poorly healed trauma
IMAGING, ORTHOPAEDICS, PAEDIATRICS
A descriptive term for the
long tubular bones of infants with thanatophoric dwarfism* (bottom image), which have been fancifully likened to the handheld part of an old two-piece telephone. The bones are short, broad with metaphyseal flaring, occasionally display “cupping” of end-plates; afflicted bones have a rhizomelic distribution and are markedly curved at the ends; other bone anomalies include the cloverleaf skull deformity, frontal bossing and H- or U-shaped vertebral bodies–discussed elsewhere.
*Thanatophoric dwarfism type 1 (OMIM:187600) and 2 (OMIM:187601) are both caused by defects of FGFR3, which encodes a receptor for fibroblast growth factors that plays a key role in regulating chondrocyte differentiation, proliferation and apoptosis, skeletal development, osteogenesis, angiogenesis, wound healing, cell migration, neural outgrowth and embryonic development
