Intervertebral disc degeneration is considered to be a major feature of low back pain. Furthermore, oxidative stress has been shown to be an important factor in degenerative diseases such as osteoarthritis and is considered a cause of intervertebral disc degeneration. The purpose of this study was to clarify the correlation between oxidative stress and intervertebral disc degeneration using Broad complex-Tramtrack-Bric-a-brac and cap'n'collar homology 1 deficient (Bach 1-/-) mice which highly express heme oxygenase-1 (HO-1). HO-1 protects cells from oxidative stress. ⋯ Oxidative stress prevention may avoid the degenerative process of the intervertebral disc after puncture, reducing the number of apoptosis cells. High HO-1 expression may also inhibit oxidative stress and delay the process of intervertebral disc degeneration.

Different approaches for disc regeneration are currently under investigation. Beside gene therapy and tissue engineering techniques, the application of growth and differentiation factors own promising potential. Studies using reduced intervertebral disc models, such as cell or tissue fragment cultures, have limited validity and show controversial results depending on the employed experimental model. Therefore, the goal of the current study was to investigate the effect of BMP-2 and TGF-β3 on intervertebral disc degeneration using an in vitro full-organ disc/endplate culture system. ⋯ It can be concluded that both growth factors, at the tested concentrations, may not be suitable to regenerate the whole intervertebral disc organ but they are interesting candidates for being injected alone or in combination into a painful intervertebral disc to induce osseous fusion (spondylodesis).

Review Meta Analysis
Balloon kyphoplasty versus percutaneous vertebroplasty in treating osteoporotic vertebral compression fracture: grading the evidence through a systematic review and meta-analysis.
To assess the safety and efficacy of balloon kyphoplasty (KP) compared with percutaneous vertebroplasty (VP) and provide recommendations for using these procedures to treat osteoporotic vertebral compression fractures (OVCF). ⋯ KP and VP are both safe and effective surgical procedures for treating OVCF. KP may be superior to VP in patients with large kyphosis angles, vertebral fissures, fractures in the posterior edge of the vertebral body or significant height loss in the fractured vertebrae. Due to the poor quality of the evidence currently available, high-quality RCTs are required.

To determine the level of evidence for altered mechanical and motor control of the pelvis being associated with pregnancy-related pelvic girdle pain (PPGP). ⋯ The level of evidence for an association between PPGP and altered motor control and kinematic or kinetic parameters of the pelvis was found to be moderate.

The life span of cancer patients has improved due to advancements in cancer management. With long survival periods, more patients show metastatic disease. Osteolytic tumours of spine are generated by metastatic deposits or primary tumours of the spine. A prospective study was performed to evaluate the efficacy and safety of percutaneous kyphoplasty in patients with osteolytic tumours of the thoracic and lumbar spine. ⋯ Kyphoplasty is a suitable palliative treatment option for patients with advanced metastatic disease of the spine even with low Tokuhashi scores allowing rapid pain relief and mobilisation to increase the quality of life.
