Definition

Tibial hemimelia-polysyndactyly-triphalangeal thumb syndrome is a rare, genetic dysostosis syndrome, with marked inter- and intra-familial variation, typically characterized by triphalangeal thumbs, hand and/or foot polysyndactyly and/or absent/hypoplastic tibiae (associated with duplication of fibulae in some cases), although isolated triphalangeal thumbs have also been reported. It is often accompanied with remarkable short stature and additional features may include radio-ulnar synostosis and hand oligodactyly, as well as abnormal carpal and metatarsal bones. [from ORDO]

Clinical features

From HPO
Triphalangeal thumb
MedGen UID:
66029
•Concept ID:
C0241397
•
Congenital Abnormality
A thumb with three phalanges in a single, proximo-distal axis. Thus, this term applies if the thumb has an accessory phalanx, leading to a digit like appearance of the thumb.

87498
•Concept ID:
C0345354
•
Congenital Abnormality

Fibular duplication
MedGen UID:
478372
•Concept ID:
C3276742
•
Finding
Duplication of the fibula. This may occur as a part of diplopodia (accessory tarsal or metatarsal bone). Diplopodia with double fibula is an extremely rare condition.
