ABSTRACT

As the population of the United States undergoes significant qualitative and quantitative changes the healthcare needs of the population changes accordingly. Since the “old-old” ≥85 years sector of the population is growing fast we embarked on studying how spine surgery profile changes across age groups. Methods: A database of 6147 spine surgery patients operated in a tertiary care center in Middle Georgia between 2003 and 2009 was divided to four age groups. The threshold for old-old age was set at 75. The percentage of old-old patients was calculated and their spine surgery profile for the whole period was studied. Changes in spine surgery profile were evaluated in relation to age group and gender. Type of surgery was determined by ICD-9 code. Results: For the whole study period, the percentage of old-old spine surgery patients was 6.7%. The percentage of old-old spine surgery patients increased from 4.7% in 2003 to 7.3% in 2009. Females were preponderant in the later three age groups (53.8%, 53.2% and 55.0%) while males were more in the <40 group (52.8%). Significant differences in the spine surgery profile between age groups were detected (Χ2 = 1446.958, P = 0.000). The spine surgery profile for the whole study period was characterized by shifts in the ≥75 age group toward less primary fusions of the cervical and lumbar spine and more refusions of the lumbar spine, more intervertebral disk excisions and more canal exploratory operations in older-old patients. In addition to the age factor, the gender factor had an impact on the spine surgery profile. Statistically significant differences (P < 0.5) were noted between males and females in each age group. Conclusions: Spine surgery profile shows a tendency toward less invasive procedures in the older-old population unless indicated by previous surgery failures, upper neck injuries or osteoporosis-induced fractures.
