Epidural steroid injection has been frequently performed to treat chronic pain due to lumbosacral disc herniation (L-HIVD). However, a considerable number of patients do not achieve pain relief using this method because perineural or epidural adhesions prevent the spread of injectate into the epidural space. Percutaneous adhesiolysis (PA) is thought to be a useful method because it can eliminate the deleterious effects of adhesion. ⋯ PA with NaviCath® showed clinical effectiveness in the treatment of chronic pain due to L-HIVD that was not responsive to transforaminal epidural injection. Previous surgery and the presence of spinal stenosis or spondylolisthesis were poor prognostic predictors. This procedure may enable the physician to place the catheter tip and deliver medicine more precisely.

The current study examined the prospective relationship between pain-related fear and altered motor behavior, as well as perceived interference, among 51 healthy participants following induction of delayed-onset muscle soreness (DOMS) to the trunk extensor muscles. Healthy participants without history of back pain completed standardized reaches to high and low targets at self-paced and rapid speeds before and after induction of acute low back pain using a DOMS paradigm. Pain-related fear was assessed prior to DOMS induction. ⋯ Pain-related fear scores were not predictive of lumbar flexion during baseline, but predicted reduced lumbar flexion during self- and fast-paced trials to low target locations once DOMS was induced. Pain-related fear was likewise predictive of perceived interference in life activities following DOMS induction. The findings suggest that initially pain-free individuals with high pain-related fear adopt avoidant spinal strategies during common reaching movements shortly after injury is sustained, which may comprise a risk factor for future pain and disability.

Understanding catastrophizing from a misdirected problem-solving perspective.
The aim is to explore pain catastrophizing from a problem-solving perspective. The links between catastrophizing, problem framing, and problem-solving behaviour are examined through two possible models of mediation as inferred by two contemporary and complementary theoretical models, the misdirected problem solving model (Eccleston & Crombez, 2007) and the fear-anxiety-avoidance model (Asmundson, Norton, & Vlaeyen, 2004). ⋯ These findings provide support for viewing catastrophizing from a problem-solving perspective and imply a need to examine and address problem framing and catastrophizing in back pain patients.

Randomized Controlled Trial
Oxiplex reduces leg pain, back pain, and associated symptoms after lumbar discectomy.
Prospective, randomized, blinded clinical trial. ⋯ These data demonstrate improvements in clinical outcomes resulting from the use of Oxiplex gel in discectomy procedures for treatment of lumbar disc herniation.
