Polydactyly
What is syndactyly? Syndactyly is the webbing or fusing together of two or more fingers or toes.[web.archive.org]
Polydactyly can occur as an isolated disorder (non-syndromic polydactyly) or as a part of an anomaly syndrome (syndromic polydactyly).[ncbi.nlm.nih.gov]
Sometimes the extra digit is connected to the hand or foot with only a narrow piece of tissue.[cincinnatichildrens.org]
Syndactyly
I believe it advisable to leave the third metacarpal in place and not to narrow the hand by removing it and shifting the index ray ulnarward.[ncbi.nlm.nih.gov]

This study reports the first frameshift mutation in the BHLHA9 causing mesoaxial synostotic syndactyly and phalangeal reduction.[ncbi.nlm.nih.gov]
Ectrodactyly
On both of his hands he is missing his second digit (Ectrodactyly) and has a double thumb (Syndactyly) and on both his feet he is also missing his second digit.[community.babycenter.com]
[…] and the hand is cleft where the metacarpal of the finger should… It seems that disorders affecting the digits are almost always hereditary and inherited – and likely dominant[thehumanmarvels.com]
In the past, doctors have typically tried to repair and close the cleft in attempt to give the hand and/or foot a more normal appearance and a narrower shape.[justanotherlittlemiracle.blogspot.com]
Saethre-Chotzen Syndrome
Saethre-Chotzen syndrome (SCS) is a type of acro-cephalo-syndactyly (ACS) syndrome, characterized by premature fusion of the coronal sutures, facial dysmorphism, syndactyly[ncbi.nlm.nih.gov]
Abstract Craniosynostosis (premature fusion of the skull sutures) occurs as a clinically heterogeneous group of disorders, frequently involving digital abnormalities.[ncbi.nlm.nih.gov]
( dolichocephaly ) [4] Head is short from front to back [5] Lopsided face [4] Low-set hairline causing forehead to appear tall and wide [5] Defects of the hands and feet[en.wikipedia.org]
Smith Lemli Opitz Syndrome
At autopsy the infant had hydrops, unusual face, cleft palate, genital abnormalities, Dandy-Walker malformation, and absence of toe syndactyly.[ncbi.nlm.nih.gov]

Other dysmorphic features may include microcephaly, ptosis, epicanthal folds, short nasal bridge, bitemporal narrowing, and micrognathia.[jneurodevdisorders.biomedcentral.com]
Oculodentodigital Dysplasia
We observed bilateral syndactyly in 32 patients, with symmetric involvement in 31 of these.[ncbi.nlm.nih.gov]
Oculodentodigital dysplasia (ODDD) (OMIM #164200) is a rare congenital, autosomal dominant disorder comprising craniofacial, ocular, dental, and digital anomalies.[ncbi.nlm.nih.gov]
Abnormalities observed in ODDD affect the eye, dentition, and digits of the hands and feet.[ncbi.nlm.nih.gov]

Surgery may also be used to narrow the nose and reduce neck webbing.[rarediseases.org]
Central Polydactyly of Fingers

The boy’s condition, polydactyly, is a relatively rare genetic disorder. Usually with this condition, the extra digits are on the little finger side of the hand.[nydailynews.com]
One theory gaining recognition is the role of digital vasoconstriction (narrowing of blood vessels).[anatomybox.com]

Treatment of Polydactyly If the duplicated small finger is hypoplastic, rudimentary, and attached to the hand by a narrow pedicle it can be removed in the newborn.[boneandspine.com]
Brachydactyly
Ophthalmoscopy showed mild narrowing of retinal arteries. Serum electrolytes, blood gases, and renal function were normal.[ncbi.nlm.nih.gov]

We compared the findings in our case with those of brachydactyly B, Fuhrmann syndrome and Haas-type syndactyly.[ncbi.nlm.nih.gov]
