What causes polydactyly deformity

The development of polydactyly in patients is mainly related to genetic factors and adverse environmental exposure factors during pregnancy. Polydactyly is associated with abnormal development factors of the top ectodermal ridge, including abnormal thickening or delayed retraction. Most of the diseases caused by genetic factors are caused by abnormalities in chromosomes 2 and 7. Environmental factors are mainly due to smoking, viral infection, radiation exposure or a history of adverse drug use during pregnancy. In addition, pregnancy-related comorbidity can also lead to polydactyly malformation. Patients can choose the corresponding treatment method according to the specific degree of their condition. Surgical treatment is usually considered, and everyone must choose the right opportunity.
