Comparative StudyApplication of holmium:YAG laser in epiduroscopy: extended practicabilities in the treatment of chronic back pain syndrome.
Minimally invasive and endoscopic techniques offer advantages in the treatment of chronic back pain syndrome and may provide for expanded indications and visualization. Epiduroscopy for the visualization of the epidural space still is burdened with technical problems. The mechanical instruments now available, coupled with the narrow working canal, result in marked limitations. The aim of this study was to assess the possibilities and technical requisites for the use of the holmium:YAG laser in lumbar epiduroscopy. ⋯ The results show that the holmium:YAG laser considerably expands therapeutic possibilities and aids in solving the technical problems of epiduroscopy. No negative effects occurred when the laser is used.

Mechanical effects of leg position on vertebral structures examined by magnetic resonance imaging.
Leg manipulation has been postulated to affect spinal curvature and position of the cauda equina within the dural sac. However, no evidence of such mechanical effects has been shown in living subjects. We used magnetic resonance imaging to evaluate the mechanical effects of leg position on these 2 parameters. ⋯ Our findings indicate that 2 potential factors, flattening of the lumbar lordosis and some added tension on the lumbosacral nerve roots, may contribute to postoperative back and leg aching after spinal anesthesia in the lithotomy position.

Effectiveness of transforaminal epidural steroid injections in low back pain: a one year experience.
Transforaminal epidural steroid injections under fluoroscopy are an alternative treatment for lower back pain with radiculopathy. We followed 82 patients with a standardized telephone questionnaire at 2, 6, and 12 months after the first injection, in order to assess their effectiveness. Ninety-two patients with radiculopathic back pain due to spinal stenosis, herniated discs, spondylolisthesis, and degenerated discs, underwent transforaminal epidural steroid injections under fluoroscopy. ⋯ After one year, 36 patients did not take any pain medications. Greater than 50% improvement after one year was seen in 23% of Group I; 59% in Group II; 35% in Group III and 67% in Group IV. Transforaminal epidural steroid injections can offer significant pain reduction up to one year after initiation of treatment in patients with discogenic pain and possibly in patients with spinal stenosis.

The objective of this study was to examine the programming strategies used in patients with intractable low-back pain treated with epidural spinal cord stimulation (SCS) utilizing paddle electrodes and a radio frequency (RF) stimulator. Programming strategies were examined in a group of patients implanted with a 16-contact paddle electrode and a dual channel RF receiver to treat chronic low-back pain. Baseline data included previous surgical history information, leg and low back pain severity and characteristics, and routine demographic information. ⋯ The system must provide the capability to redirect the current electronically over at least two segments of the spinal canal, to electronically steer the current in a medio-lateral direction, and to activate multiple electrical contacts simultaneously. The willingness and ability to provide extensive reprogramming in the long term follow-up is also of the utmost importance. Pain and its treatment with SCS is a dynamic process.
