Lumbar hernia as congenital aplasia of lumbo-dorsal muscle.
A newborn with congenital aplasia of the dorso-lumbar muscles is described. The lesion seemed to be a congenital lumbar hernia and is a very uncommon feature. The child underwent surgery and although it was a very large bilateral defect, it was repaired without using prosthetic patch. The surgical technique and the results are discussed. The function of the region was conserved as demonstrated at the check-up of the child at 6 and 12 months of age.
