Influence of Corticosteroid Injections on Postoperative Infections in Carpal Tunnel Release.
PURPOSE: Corticosteroid injections (CSIs) are commonly used in carpal tunnel syndrome; however, recent literature has demonstrated risk of postoperative infection associated with preoperative CSIs in other orthopedic fields. The aim of this study was to assess the relationship of CSIs and postoperative infection following carpal tunnel release (CTR).
METHODS: A single-center retrospective review was conducted from 2010 to 2019 to identify patients who underwent CTR with subsequent antibiotic prescription for chart-documented wound infection. A demographically-matched cohort of 100 patients was identified for comparison. Information on patient demographics, comorbidities, injection history, and presence of postoperative infection was collected.
RESULTS: Thirty-nine patients (0.67% of all CTR patients) were identified with postoperative infections, 3 of which (0.05% of all CTR patients) were deep infections. In the infection cohort, 16 of 39 (41%) patients received an injection prior to surgery, whereas 16 of 100 (16%) patients in the control cohort received an injection. History of CSI was significantly more common in patients with postoperative infection, and patients in the infection cohort had a significantly shorter average time from injection to surgery by approximately 55 days.
CONCLUSIONS: Corticosteroid injections in the preoperative period are associated with postoperative infection after CTR. Proximity of injection to time of surgery plays a role, although comorbidities, the corticosteroid dose, and frequency of injection require further study to determine risk contribution.
TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic III.
