periosteal stripping in the long lower limb bones of thirty children with shortening after poliomyelitis was performed. All have been followed up for five years. A relative increase in length attributable to the periosteal stripping procedure was seen in the majority. The conclusions are that this simple procedure is indicated in minor degrees of limb inequality in growing children, but that the haphazard response precludes any accurate estimation of the final outcome of such a procedure.

Halo pelvic traction, a method of correcting the deformed spine, is discussed and experience with treatment of our first twenty-five patients presented.
