Therefore, the analyses of variables were restricted to the groups of cases that had isolated phocomelia versus those with MCA. Other abnormalities may be observed: Other areas of the body are also affected by malformations, such as the face, skull, reproductive organs, anus and pelvis. The hand and foot plates become separated from the proximal segment of the limb by aelia circular constriction, which becomes the wrist and ankle, and later a second constriction at the level of the elbow and knee divides the proximal portion into two segments, foomelia that the foconelia segments of the limb proximal stylopod, middle zeugopod, and distal autopod can be recognized.
Problems of misclassification could be present also in the scarce data on the prevalence of phocomelia in the literature. Canfield9 Eduardo E.
