To evaluate the effect of hyaluronidase in lumbar interlaminar epidural injection (LIEI) for low back pain and sciatica. ⋯ LIEI with triamcinolone and hyaluronidase is more effective for reducing pain after 8 weeks than injection with triamcinolone or hyaluronidase alone.
-
To compare the technical strengths and weaknesses between retrodiscal (RD) and conventional subpedicular (SP) approaches of transforaminal epidural block (TF-EPB). ⋯ The RD approach was as efficient as the SP approach for temporary diagnostic relief and offered considerable advantages, such as lower nerve root irritation possible lower risk of vascular injection. Thus, it could be a useful technique when a herniated disc segment is stuck or when the foraminal stenosis is severe.

To assess the usefulness of a pressure algometer to measure pressure pain threshold (PPT) for diagnosis of myofascial pain syndrome (MPS) in the upper extremity and trunk muscles. ⋯ The digital pressure algometer showed high reliability. PPT might be a useful parameter for assessing a treatment's effect, but not for use in diagnosis or even as a screening method.

To compare the short-term effects and advantages of transforaminal epidural steroid injection (TFESI) performed using the conventional (CL) and posterolateral (PL) approaches. ⋯ Our findings suggest that the posterolateral approach represents an alternative TFESI method in cases with difficult needle tip positioning in the anterior epidural space, and could lower the risk of target nerve root irritation and nerve penetration.
