Surgical Fixation of Thoracolumbar Fractures in Patients Older than 80 Years.

Background And Objective: The global average life expectancy has been increasing steadily as the quality of healthcare continues to improve. However, there is a paucity of data looking at surgical fixation of thoracolumbar spine fractures in patients ≥80 years (super-elderly). Aim of this study is to look at whether there is higher rate of complications from surgical fixation of thoracolumbar fractures in this group of patients.

Methods: We performed a retrospective study of patients who underwent surgical fixation of thoracolumbar spine fractures from 2019 to 2023. Patients were dichotomized into those who were 80 years old and above (super-elderly) and those younger than 80 years (control). Variables include sex, age, Charleston comorbidity index, presence of osteoporosis, length of hospital stay, complications, 6- and 12-months' implant status, and mortality. Incidence of revision surgery, rate of implant loosening, and mortality between the 2 groups were analyzed.

Results: Total of 108 patients were included, 43 patients in the super-elderly group and 65 in the control group. Despite the super-elderly having a higher rate of osteoporosis and higher proportion of patients with severe comorbidities (P < .0001), there was no significant difference in the rate of implant loosening at 12 months' follow-up (P = .467) or all-cause mortality (P = .158). There were no significant differences between the 2 groups regarding revision surgery (P = .923) needed either.

Conclusion: The super-elderly had a higher incidence of osteoporosis and worse comorbidities, but there was no significant difference regarding implant complications, revision surgery required, or all-cause mortality. Hence, surgical fixation of thoracolumbar spine fractures in people older than 80 years should be considered despite their advanced age.
