Common Congenital Limb Defects

Congenital limb defects include missing, incomplete, supernumerary or abnormal limbs developed at birth.

Congenital limb defects include missing, incomplete, supernumerary or abnormal limbs developed at birth. Limb defects Congenital limb amputations and imperfections are missing or incomplete limbs at birth. The overall prevalence is 7.9 / 10,000 live births. Most follow from a primary intrauterine growth arrest or disorders are secondary to the destruction of embryonic tissue. The upper extremities are affected more frequently. Congenital limb defects can have many causes and often occur as part of various congenital syndromes. Teratogenic substances (eg. As thalidomide, vitamin A) are known causes hypoplastic / missing limbs. The most common cause of congenital amputations are vascular disorder defects such as amniotic band-related limb defects in which loosely engage Amnionstränge or merge with fetal tissue. Limb defects can be: Longitudinal (common) Transversal For longitudinal defects specific undesirable developments can be observed (eg complete or partial absence of a spoke of a calf or shin.). Radial rays deficiency is the most common defect of the upper limbs and hypoplasia of the fibula is the most common deficiency of the lower limbs. About two-thirds of cases are associated with other congenital diseases, including Adams-Oliver syndrome (aplasia cutis congenita with partial aplasia of the cranial bones and the transverse limb malformations), Holt-Oram syndrome, TAR syndrome (thrombocytopenia-absent radius) and VACTERL ( vertebral anomalies, anal atresia, cardiac malformations, tracheoesophageal fistula, renal anomalies and radially aplasia and limb anomalies).
