Zellweger syndrome: an older child with progressive foot deformity

Zellweger spectrum disorders result from defects in the assembly of the peroxisome and are sometimes referred to as peroxisome biogenesis disorders. Orthopedic manifestations of this condition are variable. This case report illustrates an ambu- latory child with Zellweger syndrome and progressive foot deformity. The course of treatment consisted of initial soft tissue surgery, early recurrence of the deformity, followed by successful arthrodesis.
