EP6.89 Characteristics of Central Sensitization-Related Symptoms in Patients with Preoperative Hip Surgery: A Comparative Study

Abstract Central sensitization (CS) is linked to poor postoperative outcomes in several hip surgeries. Identifying and managing CS-related symptoms before surgery could enhance results, highlighting its significance. This study utilized the Central Sensitization Inventory (CSI) to assess CS. The CSI consists of 25 questions evaluating CS-related symptoms, encompassing physical symptoms, emotional distress, headache/jaw symptoms, urological symptoms, and sleep disorders. In this study, individual CSI scores were compared between the Early osteoarthritis (OA) and Late OA groups, and correlations between pain VAS and each CSI score within both groups were examined. The study included 30 patients with acetabular labral tear before hip arthroscopy (Early OA group: 20 females, 10 males; mean age 39.3 ± 16.1 years) and 30 patients with end stage hip OA before total hip arthroplasty (Late OA group: 25 females, 5 males; mean age 60.4 ± 14.4 years). In the Early OA group, higher scores for headache/jaw symptoms were observed (P = 0.005), but no correlation with pain VAS was found (ρ = -0.204, P = 0.351). Conversely, in the Late OA group, CSI scores for sleep disorders were elevated compared to the Early OA group (P = 0.04), exhibiting a positive correlation with pain VAS (ρ = 0.543, P = 0.003). These findings imply that such symptoms could influence postoperative outcomes, necessitating careful consideration. Further research is imperative to devise targeted interventions for managing CS-related symptoms and enhancing patient outcomes.
