Triphapangeal thumb
Triphalangeal thumb (TPT) is a congenitalmalformation where the thumb has three phalanges instead of two. The extra phalangeal bone can vary in size from that of a small pebble to a size comparable to the phalanges in non-thumb digits. The true incidence of the condition is unknown, but is estimated at 1:25,000 live births.in about two-thirds of the patients with triphalangeal thumbs, there is a hereditary component. Besides the three phalanges, there can also be other malformations. It was first described by Columbi in 1559.
Diamond-Blackfan anemia (DBA) is a rare blood disorder that occurs when the bone marrow fails to make red blood cells, which are essential for carrying oxygen from the lungs to all the other parts of the body.
Oh my god I have this I never see anyone with this My extra phalange was removed when I was two but now my range of motion is quite low
Well not everyone with triphalangeal thumbs has Diamond Blackfan Syndrome. I’m reading the symptoms associated and literally the only ones I personally have (as well as my dads side and my cousins) It’s an issue with the 7q36 chromosome :)
I wish I could post pictures so I could show my reconstructed thumbs
