Abstract
BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) is a mature and popular surgery for treatment of lumbar disc herniation (LDH). The main objective of our study was to identify risk factors for residual low back pain after PELD and to improve postoperative management.
MATERIAL AND METHODS: We retrospectively analyzed the clinical and imaging data of 251 patients who underwent PELD for LDH. We defined residual LBP as visual analog scale (VAS) score for LBP ≥3 at 2 years postoperatively, and severe LBP was defined as VAS for LBP ≥7.5. The clinical and imaging data were analyzed by comparing patients with VAS scores ≥3 and <3, and univariate analysis and multivariable logistic regression analysis were applied to predict the risk factors for residual LBP.
RESULTS: There were 56 (22.3%) patients with LBP VAS ≥3 at 2 years postoperatively. Multivariable logistic regression analysis demonstrated that severe baseline VAS for LBP (P<0.001), MCs type I (P=0.006), and severe fatty infiltration of the paravertebral muscles (P<0.001) were independent risk factors for residual LBP after PELD.
CONCLUSIONS: In patients with LDH, MCs type I, severe baseline LBP, and fatty infiltration of the paravertebral muscles were predictive factors for residual LBP after PELD. Our study suggests that spine surgeons should pay more attention to these imaging parameters, which may be a helpful indicator for the choice of surgical modality.
