Randomized Controlled Trial Comparative Study
Clinical study of low back pain and radicular pain pathways by using l2 spinal nerve root infiltration: a randomized, controlled, clinical trial.
Randomized control trial (RCT) for L2 spinal nerve infiltration (L2 block) in clinical cases. ⋯ The LBP and radicular pain pathways were likely interrupted by L2 block. An L2 block is useful in reducing LBP due to the disorders of L2 spinal nerve-innervated structures, such as the disc, facet joint, and sacroiliac joint. However, the therapeutic value of an L2 block may be occasionally insufficient to alleviate pain completely because of the short duration of its' effect.

Controlled laboratory study. ⋯ These findings provide baseline information to enable the study of kinematic changes that occur in pathologic conditions of the spine and to determine how these might be affected following surgical intervention.

Prospective cohort study. ⋯ Larger anular defects and less disc removal increased the risk of reherniation. Greater volumes of disc removal were associated with accelerated disc height loss. In the setting of larger anular defects or less aggressive disc removal, concern for recurrent herniation should be increased during outpatient follow-up. In this situation effective anular repair may be helpful.

Randomized Controlled Trial
Evaluation of the effectiveness and efficacy of Iyengar yoga therapy on chronic low back pain.
The effectiveness and efficacy of Iyengar yoga for chronic low back pain (CLBP) were assessed with intention-to-treat and per-protocol analysis. Ninety subjects were randomized to a yoga (n = 43) or control group (n = 47) receiving standard medical care. Participants were followed 6 months after completion of the intervention. ⋯ Yoga improves functional disability, pain intensity, and depression in adults with CLBP. There was also a clinically important trend for the yoga group to reduce their pain medication usage compared to the control group.

Case Reports
Management of traumatic cervical spondyloptosis in a neurologically intact patient: case report.
Case report. ⋯ Fractures of the posterior elements functionally decompress the spinal canal and thereby allow for cervical traction to be safely implemented in patients with spondyloptosis. Safe restoration of anatomic alignment in the neurologically intact spondyloptotic patient is crucial to minimize the extent of surgical stabilization and create a long-term stable construct of the fracture dislocation.
