ReviewIs lumbar discography a determinate of discogenic low back pain: provocative discography reconsidered.
Provocative lumbar discography was investigated in a series of clinical studies at the Stanford University of Medicine, Stanford, CA. This work demonstrated that pain intensity during disc injection is strongly influenced by the subject's emotional and psychological profiles, chronic pain behavior, and ongoing compensation claims whether the patient has any back pain illness or not. Pain reproduction was also primarily related to penetration of the dye through the outer annulus and could not reliably be used to confirm the location of the pain source.

Multicenter Study
Acute low back pain: predictive index of chronicity from a cohort of 2487 subjects. Spine Group of the Société Française de Rhumatologie.
Low back pain (LBP)-related disability involves patients with chronic outcome. ⋯ The early recognition of patients with LBP with high risk of chronic outcome can be achieved with an easily applied clinical index.

Case ReportsEnlargement of a chronic aseptic lumbar epidural abscess by intraspinal injections--a rare cause of progressive paraparesis.
The frequent use of invasive procedures at the spinal cord such as epidural injections has led to an increased incidence of iatrogenic abscesses. We report the case of a patient who suffered from low back pain. During epidural lumbar injections of steroids the patient developed severe radicular symptoms, resulting in severe paraparesis. ⋯ The authors prove that the cause of the neurological deterioration was due to epidural injections into a preexisting lumbar chronic aseptic epidural abscess. Harmful and unpleasant complications may occur following epidural injections. Though we present a very rare cause of such complications, a careful monitoring of the neurological status of the patient is necessary as well as the early application of MR imaging in the case of deterioration.

Comparative StudyBack and hip extensor activities during trunk flexion/extension: effects of low back pain and rehabilitation.
To compare lumbar paraspinal, gluteus maximus, and biceps femoris muscle function during sagittal trunk flexion and extension in patients with chronic low back pain and healthy control subjects, and to assess the influence of rehabilitation in the back pain patients. ⋯ The activity of the gluteus maximus muscle during the flexion-extension cycle was reduced in patients with chronic low back pain. The gluteal muscles should be taken into consideration in the rehabilitation of these patients.

The authors report their experience with 42 patients in whom anterior lumbar fusion was performed using titanium cages as a versatile adjunct to treat a wide variety of spinal deformity and pathological conditions. These conditions included congenital, degenerative, iatrogenic, infectious, traumatic, and malignant disorders of the thoracolumbar spine. Fusion rates and complications are compared with data previously reported in the literature. ⋯ The complication rate mirrors the low morbidity rate associated with the anterior approach. A detailed study of clinical outcomes is in progress. Patient selection and strategies for avoiding complication are discussed.
