Clinical Effect of Selective Serotonin Reuptake Inhibitors (SSRIs) on Fracture Healing
Abstract
PURPOSE: Chronic use of selective serotonin reuptake inhibitors (SSRIs) for the treatment of depression has been linked to an imbalance in bone metabolism leading to osteoporosis. More recently, the use of SSRIs in murine models has been shown to delay bone healing both in vivo and in vitro by decreasing the osteoblastic differentiation and mineralization. The purpose of this study was to evaluate whether or not chronic use of SSRI's in nonunion patients increases their time to union after surgical intervention.
METHODS: We retrospectively analyzed 343 patients in a nonunion database to determine which patients were on SSRI medication. Of these patients, 139 could be contacted and of those 102 were not taking SSRIs and 37 were taking SSRIs. Patient's time to union from nonunion surgical intervention between each cohort at our institution was recorded as the primary outcome. Patient's medical comorbidities that could affect union rates such as diabetes and smoking status were also noted. Baseline Short Musculoskeletal Function Assessment (SMFA) index for bother and function were recorded from the time of nonunion surgery as well as last follow-up.
RESULTS: Compared to recent census data, we found significantly more patients in the nonunion cohort using SSRIs (26.6%) than patients in the general population using any type of antidepressant (11%). There was no significant difference in the patients' baseline characteristics other than patients on SSRI treatment had a higher body…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 343 participants or records.
