Paraxial Macrodystrophia Lipomatosa of the Medial Right Lower Limb

Abstract

We report the orthopaedic management of a child with macrodystrophia lipomatosa of the medial aspect of the right lower limb. Bony and soft tissue overgrowth of the medial aspect of the lower limb resulted in valgus deformities at the subtalar joint, ankle, knee, and hip. The paraxial distribution, which has not been previously reported, suggests that the condition may be caused by alteration of somatic cells during limb bud development.
