| Abstract: | A Pre‐Columbian skeletal sample (n=42) from two ancestral Pueblo sites in the Rio Grande valley of west‐central New Mexico was examined for frequency and severity of spondylosis deformans (vertebral osteophytosis). No significant sex differences were detected. Degenerative changes in the collective sample are generally confined to no more than well‐defined horizontal lipping at the joint margins. Advanced proliferative osteophytic change is infrequent even in the oldest age category. Not surprisingly, the lumbar vertebrae were the most frequently and most severely involved vertebral segment for all three adult age cohorts defined. The cervical vertebrae were the least involved. This pattern generally conforms with observations made on other archaeological samples from west of the Mississippi River, but it contrasts with the general pattern of more extensive cervical involvement in Pre‐Columbian North American samples from the Eastern Woodlands. This possible east–west difference is hypothesized (Bridges, P.S. 1994. American Journal of Physical Anthropology 93: 83–93) to be related to differential burden bearing habits.
