In order to evaluate the clinical results and validity of the heel cord advancement for treatment of recurred spastic equinus deformity, we evaluated 36 equinus feet in 23 patients with cerebral palsy who had been treated with heel cord advancement. There were thirteen boys and ten girls, ranging in age from 2 years and 11 months to 13 years and 8 months, on an average 7.9 years. Surgeries were performed on both feet in 13 patients, right foot in 6 patients and left foot in 4 patients. The mean time from the operation to the most recent follow-up was 2.7 years. Of 23 patients, 12 had paraplegia, 8 diplegia. The remainders were quadriplegia, hemiplegia and monoplegia, respectively. We employed the original technique of heel cord advancement devised by Murphy, and evaluated the final results according to the Pierrot and Murphy's criteria. By this criteria the clinical results were excellent in 33.4%, good in 58.3%, poor in 8.3%. In conclusion, we believe that the heel cord advancement is an effective salvage prodedure for treatment of recurred spastic equinus deformity in cerebral palsy.
