Comparative StudyClinical grading of spinal osteoporosis: quality of life components and spinal deformity in women with chronic low back pain and women with vertebral osteoporosis.
Clinical consequences of osteoporotic vertebral fractures, such as back pain, functional limitations, and impairment of mood, are often cited as justification for prevention and therapy. But these symptoms are poorly characterized, and a clinical grading system is not available. The aim of this study was to compare clinical measures for spinal deformation and quality of life components between patients with osteoporosis and patients with chronic low back pain (CLBP) and to determine the relationship between spinal deformation and quality of life components. ⋯ We conclude that with respect to quality of life components, functional limitation is the most specific to spinal osteoporosis and is related to clinical measures of spinal deformation. Furthermore, spinal deformation and the clinical course of osteoporosis appears to be insufficiently reflected by radiological indices of vertebral deformity (such as SDI) alone. For grading the disease and for therapeutical concepts, radiological measures and clinical evaluation should be considered in combination.

The purpose of this study was to assess the relationship between the nonorganic signs (Waddell scores) of patients with low back pain, their response to repetitive end-range lumbar spine test movements (centralization of symptoms), and the rate of return to work at a 6-month follow-up. ⋯ A high Waddell score appears to be the best predictor of outcome, as indicated by return to work.

Multicenter Study Clinical Trial
Threaded titanium cages for lumbar interbody fusions.
This study evaluated safety, fusion success rate, and clinical outcome of a new lumbar interbody hollow, threaded titanium fusion cage in a multicenter, prospective 236-case program adhering to a United States Food and Drug Administration Investigational Device Exemption controlled protocol. ⋯ The Ray titanium fusion cage (Surgical Dynamics, Norwalk, CT) implant method has been found to be an effective, rapid, safe procedure for lumbar spine fusions, demonstrating a high fusion rate and clinical success with rare, serious, or permanent complications.

Comparative Study
Kinematic analysis of lumbar and hip motion while rising from a forward, flexed position in patients with and without a history of low back pain.
This study analyzed two groups of individuals during return to an upright position (extension) from a forward, bent position. Group 1 (n = 12) included individuals with no history of low back pain who were currently asymptomatic, and group 2 (n = 12) included individuals with no history of low back pain. ⋯ Participants who were currently asymptomatic but had a history of low back pain moved in a manner similar to that of participants with no history of low back pain except that they demonstrated greater lumbar motion and velocity during the initial phase of extension. This may have been the result of low back pain or a contributing factor in recurrent low back pain.
