Abstract

Objective: The term arthrogrypotic syndrome is of common usage by different medical disciplines.  The hallmarks of acromesomelic dysplasia Du Pan Syndrome are characteristic facial features, severe growth deficiency and multiple contractures.

Material and Methods: Seven children (four females and three males) age range of (1-10 years) were sought in our departments from the period of 1994-2018. All patients were given the diagnosis of arthrogryposis in other institutions. Though, all demonstrated the classical features of abnormalities which are consistent with the diagnosis of Du Pan syndrome.

Results: The distinctive clinical and radiological phenotype was consistent with Du Pan syndrome. Strikingly, multiple dislocations along the hips and knees, elbows and ankle joints were detected which gives the false impression of arthrogrypotic syndrome.

Conclusion: Unfortunately, on the one hand, the terms arthrogrypotic and or amyoplasia syndrome still prevails in many medical disciplines. The clinical phenotype is the corner stone in establishing diagnoses in the vast majority of children who are born with multiple contractures. On the other hand, it is mandatory to search for extra-skeletal malformations in patients with Du Pan syndrome.
