First described over 25 years ago, epidural lysis of adhesions (LOA) involves the mechanical dissolution of epidural scar tissue, which may directly alleviate pain and facilitate the spread of analgesic substances to area(s) of pain generation. Although it most commonly performed for lumbar failed back surgery syndrome, there is a growing body of evidence that suggests it may be effective for spinal stenosis and radicular pain stemming from a herniated disc. There is weak positive evidence that LOA is more effective than conventional caudal epidural steroid injections for failed back surgery syndrome and spinal stenosis, and that LOA is more effective than sham adhesiolysis and conservative management for lumbosacral radiculopathy. For cervical disc herniation and spinal stenosis, there is only anecdotal evidence suggesting effectiveness and safety. Factors that may contribute to the enhanced efficacy compared to traditional epidural steroid administration include the high volume administered, the use of hypertonic saline, and to a lesser extent the use of hyaluronidase and a navigable catheter to mechanically disrupt scar tissue and guide medication administration. Although LOA is widely considered a safe intervention, the complication rates are higher than for conventional epidural steroid injection.

Background and Objectives: The purpose of this retrospective study was to identify predictors of short-term outcomes associated with a lumbosacral transforaminal epidural steroid injection (TFESI). Materials and Methods: The medical records of 218 patients, who were diagnosed with lumbosacral radiculopathy and treated with a TFESI, were reviewed in this retrospective study. A mixture of corticosteroid, lidocaine, and hyaluronidase was injected during TFESI. Patients with >50% pain relief on the numerical rating scale compared with the initial visit constituted the good responder group. Demographic, clinical, MRI, and electrodiagnostic data were collected to assess the predictive factors for short-term outcomes of the TFESI. Results: A multivariate logistic regression analysis demonstrated that a shorter duration of symptoms and a positive sharp wave (PSW)/fibrillation (Fib) observed in electrodiagnostic study (EDx) increased the odds of significant improvement 2-4 weeks after the TFESI. Conclusions: Shorter duration of symptoms and PSW/Fib on EDx were predictors of favorable short-term response to TFESI.
