Foot anomalies and proximal symphalangism

Abstract

We report the case of a 2-week-old girl born at term (by vaginal delivery and without antenatal or perinatal events) who was referred as having "bilateral talipes and bilateral proximal symphalangism of little and ring fingers." The "talipes" was atypical with marked equinus and varus, but no cavus or adductus of the midfoot. Her mother had both symphalangism (absence of proximal interphalangeal joints) of middle, ring, and little fingers bilaterally and fixed pes planus with a rigid fixed hindfoot-and these deformities had also been present from birth. The maternal grandmother was similarly affected. However, the neonatal subject has an unaffected older sibling; maternal siblings are also unaffected. The three affected people did not have other obvious musculoskeletal abnormalities. Because of the coalitions, the child's atypical talipes was managed by a modified Kite's procedure. Symphalangism-coalition syndromes may be associated with conductive deafness because of fusion of the auditory ossicles.
