Serial roentgenograms of 40 patients who had 70 cervical intervertebral spaces grafted with ethylene oxide sterilized cadaver bone and 28 patients who received 44 iliac crest auto grafts for anterior cervical spine fusion, were studied. The radiological evaluation was made on the basis of settlement of intervertebral spaces, fusion rate, delayed union, non-union, graft collapse and extrusion of the graft. Indigenous methodologies were designed for the assessment of settlement of grafted intervertebral spaces in percentage. Disc space settlement was more common in autografts (93% cases) than in allografts (80% cases). The average percentage of settlement of intervertebral disc space (S%) was 22 in autografts and 28 in allografts during the first four months. By the end of eight months, allograft disc spaces settle more. No significant difference was noted in fusion rate at the end of one year viz. allografts (90% cases) and autografts (93% cases). Autograft and allograft (ethylene oxide sterilized cadaver bone) are equally useful in anterior cervical spine fusions.
