Is facet joint distraction a cause of postoperative axial neck pain after ACDF surgery?
Introduction: Intervertebral distraction in anterior cervical discectomy and fusion (ACDF) has been postulated to injure the degenerative facet joints posteriorly and increase postoperative pain and disability. This study aims to determine if there is a correlation between the amount of facet distraction and postoperative patient reported outcomes.
Methods: A retrospective cohort analysis of patients undergoing ACDF for degenerative pathologies was performed. Each patient received lateral cervical spine x-rays at the immediate postoperative time point and were split into groups based on the amount of facet distraction measured on these films: Group A: \u3c 1.5 mm; Group B: 1.5-2.0 mm; and Group C: \u3e 2.0 mm. Patients reported outcome measures were obtained preoperatively and at 1-year postoperatively. Univariate and multivariate analyses were performed to compare outcomes between groups.
Results: A total of 229 patients were included with an average follow-up of 19.8 [19.0, 20.7] months with a mean facet joint distraction of 1.7mm. There were 87 patients in Group A, 76 patients in Group B, and 66 patients in Group C. Patients significantly improved across all outcome measures from baseline to postoperatively (p \u3c 0.05). There was no difference between groups at any time point with respect to outcome scores (p \u3e 0.05). Multiple regression analysis did not identify increasing distraction as a predictor of patient outcomes.
Conclusions: There were no significant differences between patient outcomes and the amount of facet distraction after ACDF surgery. Multivariate analysis did not find a correlation between facet distraction and overall HRQOL outcome
Lumbar Decompression Using a Tubular Retractor System
Summary: Spinal stenosis and intervertebral disc herniation are the most common causes of nerve root compression and radiculopathy in the lumbar region. The symptoms from these conditions will vary widely from absent to severe and may include debilitating back and leg pain. Studies have shown positive outcomes with surgical decompression when nonoperative treatments have been exhausted. In contrast to traditional open lumbar decompression, minimally invasive techniques have been shown to decrease certain perioperative complications and shorten patient recovery time. This study will review the use of lumbar decompressive surgery using a tubular retractor system
