Risk Factors of Postoperative Low Back Pain for Lumbar Spine Disease.

A retrospective study was conducted to clarify the risk factors of postoperative low back pain (LBP) for lumbar spine disease. A total of 401 patients who underwent lumbar operation between January 2011 and December 2011 were included in this analysis. We investigated patient characteristics and surgical approaches and also compared the radiographic characteristics. The mean visual analogue scale (VAS) score decreased dramatically after the operation. The mean preoperative VAS score was greater in patients underwent posterior lumbar interbody fusion (PLIF) with longer duration of symptoms, longer operation time, and severe lumbar multifidus (LM) intramuscular adipose tissue (IMAT). The preoperative VAS score was dramatically lower in patients with lumbar herniation. The postoperative VAS score was dramatically lower in patients who underwent PLIF with longer operation time and mild LM IMAT. Postoperative LBP disappeared more often in patients who underwent PLIF with longer operation times. The number of operative levels and type of lumbar spine disease also were associated with postoperative LBP. Type of surgery, operation time, number of operative level, and type of disease were risk factors for the postoperative LBP. Patients underwent PLIF with shorter symptom duration, longer operation time severe LM IMAT, and lumber spondylolisthesis reported more severe LBP before the operation. Patients underwent discectomy with shorter operation times.

Risk Factors of Postoperative Low Back Pain for Low-Grade Degenerative Spondylolisthesis: An At Least 2-Year Follow-Up Retrospective Study.

A retrospective study was conducted to clarify the risk factors of postoperative low back pain (LBP) for low-grade degenerative spondylolisthesis. A total of 239 patients who underwent posterior lumbar fusion between January 2011 and January 2015 were included in this analysis. We investigated patient characteristics, surgical characteristics, and radiographic characteristics. The mean visual analog scale (VAS) score of LBP decreased dramatically after the operation. The mean preoperative VAS score was greater in patients with severe lumbar multifidus (LM) intramuscular adipose tissue (IMAT). The postoperative VAS score was dramatically lower in patients with shorter symptom duration. Postoperative LBP disappeared more often in patients with shorter symptom duration. LBP VAS changing showed significant differences in different symptom duration groups and LM IMAT groups. LM IMAT and symptom duration were risk factors for postoperative LBP. Patients with severe LM IMAT reported more severe LBP before the operation. Postoperative LBP disappeared more often in patients with shorter symptom duration.
