Abstract

ABSTRACT:Results in three series of spinal fusions with Harrington instrumentation for scoliosis were compared. Patient ages ranged from 9 to 22 years, and follow-up from 12 to 105 months. Cylindrical inlay facet grafting was done in all cases. Supplemental heterologous bone was used in the first series of 51 cases, autologous bone in the second series of 67 cases, and no supplemental bone in the third series of 68 cases. Only one infection and no paralysis or death occurred in the 186 patients. The pseudarthrosis rate was the same in each series. Similarity of results led to the conclusion that supplemental bone is not necessary with this technic. The advantages of not using supplemental bone were reduced operative time, less blood loss, and absence of donor site scar.
