Spondyloepimetaphyseal dysplasia with joint laxity, leptodactylic or Hall type: report of a case with normal face and literature review.

We have documented the clinical and radiological features of a girl with a severe form of spondyloepimetaphyseal dysplasia with joint laxity, leptodactylic or Hall type, which is associated with marked articular hypermobility. This condition is to be differentiated clinically from generalized hypermobility syndromes specifically Ehlers-Danlos syndrome and Larsen syndrome. The radiographic differential diagnosis is with the group of spondyloepimetaphyseal dysplasias specifically spondyloepimetaphyseal dysplasia with joint laxity and sponastrime dysplasia.
