There is a high prevalence of low back pain (LBP) in adolescent male rowers. In this study, regional lumbar spinal kinematics and self-reported LBP intensity were compared between 10 adolescent rowers with moderate levels of LBP relating to rowing with 10 reporting no history of LBP during a 15-minute ergometer trial using an electromagnetic tracking system. Adolescent male rowers with LBP reported increasing pain intensity during ergometer rowing. No significant differences were detected in mean upper or lower lumbar angles between rowers with and without LBP. However, compared with rowers without pain, rowers with pain: (1) had relatively less excursion of the upper lumbar spine into extension over the drive phase, (2) had relatively less excursion of the lower lumbar spine into extension over time, (3) had greater variability in upper and lower lumbar angles over the 15-minute ergometer trial, (4) positioned their upper lumbar spine closer to end range flexion for a greater proportion of the drive phase, and (5) showed increased time in sustained flexion loading in the upper lumbar spine. Differences in regional lumbar kinematics exist between adolescent male rowers with and without LBP, which may have injury implication and intervention strategies.

Back pain is a debilitating medical condition, often with an unclear source. Over time, back pain can affect the work and lifestyle of an individual by reducing job productivity and time spent on enjoyable activities. Discography of the intervertebral disc (IVD) is often used to diagnose pathology of the disc and determine if it may be a source for chronic back pain. It has recently been suggested that discography may lead to IVD degeneration, and has been a cause of controversy among spine care physicians. Using the results from a cadaveric experimental model, a finite element model was first validated. Then, a study was conducted to better understand the changes caused by discography on human spine mechanics. An anatomically accurate L3-L5 lumbar spine model was developed using computed tomography scans. Discography was simulated in the model as an area in the disc affected by needle puncture. The material properties in the nucleus pulposus were adjusted to match experimental data both before and after puncture. The results show that puncture of the IVD leads to increased deformation as well as increased stresses in the disc. Pressure in the nucleus pulposus found to decrease after puncture, and was calculated in the course of this study. Puncturing the IVD changes disc mechanics and may lead to progressive spine issues in the future such as disc degeneration. While discography has been the gold standard to determine if the disc was a source of back pain in patients for many years, the potential long-term degenerative effects of the procedure are only now coming into light, and must be closely examined.

Abstract Background Back pain often arises from degenerative changes in lumbar intervertebral discs and their adjacent endplates. A painful endplate is not easy to identify in patients, but could possibly be revealed by inflammatory-like ‘Modic’ changes and by a ‘vacuum phenomenon’ within the disc. We hypothesize that Modic changes and a VP often co-exist in those lumbar levels most closely associated with back pain Methods We scanned 1023 consecutive inpatients of the Department of Orthopaedics from 2015 August to 2018 August, all patients suffered from lumbar degenerative diseases, whether the patients had back pain or not were evaluated, and the prevalence and location of vacuum phenomenon(VP) and Modic changes were compared at each spinal level. Results 5115 discs were studied from 1023 patients. The number of discs showed to have a VP was 430 using CT, of the 430 discs with a CT-diagnosed VP, 116 were L4-5, and 171 were L5-S1. 522 of the 5115 discs exhibited Modic changes, with prevalence of type I, type II and type III Modic changes being 1.6%, 8.2% and 0.4% respectively. Modic changes usually occurred adjacent to L4-5 discs or L5-S1 discs. The prevalence of back pain was higher in the VP group than no-VP group, VP were significantly associated with Modic changes Type II at L4/5 and at L5/S1. Conclusion VP are closely associated with back pain and Modic changes in the lower lumbar spine. Further investigations may be warranted when radiographs or CT identify a VP in a lumbar disc.

We observed 72 people with vertebrogenic paresthetic meralgia. Thirty of them were diagnosed with osteochondrosis of the lower thoracic spine, 27 with upper lumbar spine, and 15 with lower lumbar spine. A permanent form of paresthetic meralgia was detected in 38 patients and transient paresthetic meralgia was detected in 34 patients.
