Summary
The Central Sensitization Inventory (CSI) score can assess psychosocial factors before distal radius fracture (DRF) surgery. Higher CSI scores correlate with older age and greater pain intensity (NRS), suggesting targeted preoperative care is beneficial.
Area of Science:
- Orthopedic Surgery
- Pain Management
- Psychosocial Health
Background:
- Volar locking plate fixation facilitates early recovery for distal radius fractures (DRF).
- The perioperative period presents significant psychological stress for surgical patients.
- The Central Sensitization Inventory (CSI) is a tool to evaluate psychosocial pain factors.
Purpose of the Study:
- To assess the utility of CSI scores in evaluating psychosocial factors in patients undergoing DRF surgery.
- To determine the relationship between CSI scores and various patient and clinical factors before surgery.
Main Methods:
- A study involving 22 patients undergoing volar locking plate fixation for DRF.
- Preoperative data collection included demographics, fracture details, Numerical Rating Scale (NRS), Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) score, and CSI score.
- Statistical analysis was performed to identify associations between CSI scores and other collected variables.
Main Results:
- No significant associations were found between CSI scores and sex, injury side, fracture type, or time from injury to evaluation.
- Significant positive associations were observed between CSI scores and patient age (P=0.049, r=0.424).
- A significant positive association was found between CSI scores and NRS pain scores (P=0.003, r=0.607).
Conclusions:
- CSI scores are significantly associated with age and NRS pain levels in patients awaiting DRF surgery.
- Preoperative management focusing on mental stress and pain relief, particularly for elderly patients, may improve patient outcomes.
- The CSI score is a valuable tool for assessing psychosocial aspects influencing patients with DRF before surgical intervention.
