Dysmelia can be described as the lack of an arm or leg or of portions thereof. The word comes from the Greek ”dys”, abnormal, and ”meli” limb, thus ”abnormal limb”. Dysmelia is a congenital disorder, a reduction deformity, on one or several limbs. Reduction deformities involve a lack of parts of an arm or leg.
Dysmelia effects can be divided into two types:
The transversal gives a straight, amputation-like shape, and the longitudinal produces a longer shape. One of the longitudinal bones may be missing, but there may be other bones left on the side or beneath. The reason for dysmelia damage is usually not known. There are probably many.
The occurrence of dysmelia is pretty much constant. Every year about 60 children are born in Sweden with dysmelia. Of these, 15 have only minor finger or toe damage. The others have damage to their hands or feet and upwards. In general, two thirds of these cases concern arms and one third legs.
