Case report, literature review, discussion. ⋯ The spine as primary source of infection for secondary psoas abscess should always be included in differential diagnosis. Because the prognosis of psoas abscess can be improved by early diagnosis and prompt onset of therapy, it needs to be considered in patients with infection and back or hip pain or history of spinal surgery.

A retrospective review of patients undergoing C1-C2 posterior fusion during childhood was undertaken. ⋯ In children, a spontaneous realignment of the subaxial kyphosis observed after C1-C2 posterior fusion can be noted at follow-up, when a postoperative deformity occurs (33% in the present series). According to the present findings, it is not always mandatory to perform occipitocervical fusion in children with atlantoaxial instability just to prevent subaxial deformity in the cervical spine.

Cultured annulus fibrosus cells within an atelocollagen honeycomb-shaped scaffold with a membrane seal were allografted into the lacunas of intervertebral discs of which the nucleus pulposus had been vaporized using an indocyanine green dye-enhanced laser. Regeneration of the intervertebral disc was assessed based on the viability and histologic status of the allografted annulus fibrosus cells, as well as the prevention of narrowing disc space. ⋯ The annulus fibrosus cells cultured in an ACHMS-scaffold were allografted into the lacunae of nucleus pulposus (obtained using laser vaporization), as well as the hole of annulus fibrosus (obtained by laser fiber insertion) of rabbit intervertebral discs. These cells were viable and showed cell proliferation in the disc tissues of recipients.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Manual therapy and exercise therapy in patients with chronic low back pain: a randomized, controlled trial with 1-year follow-up.
A multicenter, randomized, controlled trial with 1-year follow-up. ⋯ Improvements were found in both intervention groups, but manual therapy showed significantly greater improvement than exercise therapy in patients with chronic low back pain. The effects were reflected on all outcome measures, both on short and long-term follow-up.

Analysis of longitudinal data collected prospectively from patients seen in 27 National Spine Network member centers across the United States. ⋯ For studies of patients with low back problems, the general SF-36 may be a sufficient measure of health status and patient function, without the need for additional condition-specific instruments. Pain scales appear to be the most responsive measures in patients with low back pain.
