Grading inter-vertebral disc degeneration (IDD) is important in the evaluation of many degenerative conditions, including patients with low back pain. Magnetic resonance imaging (MRI) is considered the best imaging instrument to evaluate IDD. The Pfirrmann classification is commonly used to grade IDD; the authors describing this classification showed an adequate agreement using it; however, there has been a paucity of independent agreement studies using this grading system. The aim of this study was to perform an independent inter- and intra-observer agreement study using the Pfirrmann classification. ⋯ In this independent study, the Pfirrmann classification demonstrated an adequate agreement among different observers and by the same observer on separate occasions. Furthermore, it allows communication between radiologists and spine surgeons.

To determine if adolescent athletics increases the risk of structural abnormalities in the lumbar spine. ⋯ Adolescents with low back pain have a higher-than-expected prevalence of structural pathology regardless of athletic activity. Independent of pelvic incidence, adolescent athletes with low back pain had a higher prevalence of spondylolysis compared to adolescent non-athletes with back pain, but there was no difference in associated disc degenerative changes or herniation.

For the stabilization of the thoracolumbar spine area, various stabilization techniques have been developed in recent decades. The aim of these techniques is to immobilize the treated segment to repositioning or correct the spine and guaranty long-term stability to achieve a reliable fusion. The aim of this study was to simulate in an in vitro experiment the postoperative long-term situation in elderly osteoporotic patients to compare two different stabilization principles; a pedicle screw system and a lamina hook system. ⋯ Both implant systems provide similar primary stability and similar long-term stability. In the pedicle screw group, there was a stronger correlation between bone mineral density and the reached number of load cycles.

The present study investigated the percentage of low back pain (LBP) patients who have depressive symptoms and neuropathic pain and analyzed the effects of these on the quality of life (QOL) in these patients. ⋯ Both the depressed patients and those with neuropathic LBP had a higher level of pain, greater pain-related disability, and poorer QOL compared with nondepressed patients. This is the first study to use the SDS-Zung and PDQ-J screening questionnaires to estimate the presence of neuropathic pain associated with depressive symptoms in LBP patients and to evaluate the impact of these on QOL.

The most relevant musculoskeletal problems are related with back health. Study instruments have been designed for adult patient population but not for school-aged children. The aim of this study was to develop and evaluate the psychometric properties of a questionnaire to assess adolescents' level of back care knowledge in daily life physical activities. ⋯ The questionnaire showed acceptable psychometric values. Results showed that this questionnaire is a good instrument to assess adolescent's back care knowledge.
