Combined Congenital Radial and Ulnar Longitudinal Deficiencies: A Case Report

[摘要] The incidence of radial longitudinal deficiencies (RLD) is estimated 1 in 9,000 to 1 in 55,000 [1, 2]. The incidence of ulnar-sided defect or ulnar longitudinal deficiencies (ULD) is estimated 1 in 100,000 [1, 2]. Phocomelia is a very rare anomaly. Its prevalence was 5 in 4024000 in one series and a similar prevalence in the other series [3, 4]. Goldfarb et al. and Tytherleigh-Strong and Hooper suggested that phocomelia should be considered as proximal extensions of radial longitudinal dysplasia or/and ulnar longitudinal dysplasia [3, 4]. Combination of RLD and ULD in contra-lateral sides in the same patient is an exceedingly rare occurrence. [1] This case report describes a patient with right RLD and left ULD. The left ULD was extended proximally to become a phocomelic left upper limb.
