Orthopaedic aspects of spinal tumors in children.

A retrospective survey has been made of forty children with spinal tumours. Difficulties in establishing the correct diagnosis are mentioned and the value of radiological and cerebrospinal fluid investigations discussed. The major orthopaedic disabilities are spinal deformity or instability, and paraplegia. The main factor in the development of the former is the site of laminectomy: the higher the level the greater is the likelihood of deformity or instability developing. Measures to prevent this distressing complication are discussed. The role of the orthopaedic surgeon in the management of these children is emphasised.
