Background
Upper limbs malformations occur in approximatively 6.5 on 10000 neonates.
They are complex and knowledge of their radiological and clinical features is essential both for diagnosis and treatment planning.
Congenital upper limb malformations are divided into 1) failure of formation with transverse,
intercalary and longitudinal deficiencies (preaxial,
centroaxial,
postaxial),
2) failure of differenciation (synostosis,
syndactyly),
3) duplication (polydactyly) and 4) brachydactyly.
Sprengel deformity and congenital pseudarthrosis of the clavicle are also described.
This pictorial review is also an opportunity to cover the topics of clinodactyly,
camptodactyly and Madelung's deformity that are usually included in congenital upper limb malformations.
Other skeletal and non skeletal abnormalities must be considered to eventually diagnose:
- Embryofoetopathy (maternal valproate treatment,
constriction band syndrome),
- Genetic disorders (trisomy 21,
Turner syndrome,
Holt Oram syndrome),
- And non genetic syndromes (VACTERL,
Poland).
