Abstract
The birth prevalence of limb deficiencies in Alberta has been fluctuating. The objectives were to examine patterns and temporal trends of congenital limb deficiencies in Alberta and compare rates with those of other jurisdictions. The Alberta Congenital Anomalies Surveillance System data on live births, stillbirths, and terminations of pregnancy (P = 0.023). While the overall limb deficiency rates show very little differences across diverse populations and differing time periods, comparisons of subgroups should be made with caution, because variations in terminology and classification contribute to reported differences.
