Prognostic Indicators for Recurrent Symptoms After a Single Corticosteroid Injection for XXXX .

@entity923 @entity1 @entity228 @entity6
BACKGROUND: Corticosteroid injections are commonly used in the treatment of @entity923 in adults. This study sought to determine success rates early on and at one year postoperatively of a single corticosteroid injection while identifying prognostic indicators for symptom recurrence and repeat intervention. METHODS: Fifty-four consecutive wrists in forty-nine @entity1 with @entity923 treated with a single @entity228 injection were prospectively enrolled. Demographic data and information on comorbidities were identified with a study-specific questionnaire. The Boston Carpal Tunnel Questionnaire was administered prior to injection. @entity1 returned to clinic at six weeks and were contacted at three, six, nine, and twelve months post-injection to determine symptom and intervention status. Kaplan-Meier analysis and Cox regression modeling were used to estimate recurrence rates and to identify predictors of symptom recurrence and repeat intervention. RESULTS: Fifty-four symptomatic wrists in forty-nine @entity1 with a mean age of fifty-three years were included. Two @entity1 (two wrists) were lost to follow-up. @entity1 reported symptom recurrence in thirty-one wrists at a median duration of 155 days post-injection. Nineteen wrists underwent carpal tunnel release at a median time of 181 days after the injection. No @entity1 underwent a repeat injection. In our study, @entity6 @entity1 were at a 2.6-fold greater risk of reporting recurring symptoms within a one-year follow-up period. Survivorship free from symptom recurrence was 53% at six months and 31% at twelve months; survivorship from repeat intervention was 81% at six months and 66% at twelve months. CONCLUSIONS: A single injection achieved symptom relief in 79% of @entity1 at six weeks; these results were maintained in 31% of @entity1 at twelve months. @entity6 @entity1 were at higher risk of symptom recurrence. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
