Study: Which Patients Undergoing Transforaminal Lumbar Interbody Fusion Will Experience Postoperative Pain?
A retrospective study published online in the European Spine Journal identified risk factors associated with postoperative pain following minimally invasive transforaminal lumbar interbody fusion (TLIF). Single-level, primary minimally invasive TLIF patients were assessed for perioperative outcomes and postoperative inpatient visual analog scale (VAS) pain scores. Possible risk factors for average inpatient pain score of five or higher included age, gender, smoking status, diabetes status, insurance status, body mass index (BMI), comorbidity burden, pedicle screw laterality, operative time, and estimated blood loss. Final analysis included 255 patients. The following factors were associated with increased postoperative pain: age younger than 50 years, workers’ compensation insurance, preoperative VAS pain score of seven or higher, and operative duration of 110 minutes or longer. Gender, BMI, smoking status, comorbidity burden, diabetes status, and pedicle screw laterality were not associated with increased postoperative pain.
