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.

Facet Tropism

The aim of this study is to establish whether facet tropism (FT) and orientation (FO) are associated with degenerative lumbar spinal stenosis (DLSS). A retrospective computerized tomography (CT) study including 274 individuals was divided into two groups: control (82 males and 81 females) and stenosis (59 males and 52 females). All participants have undergone high-resolution CT scan of the lumbar spine in the same position. FT and FO were measured at L1-2 to L5-S1. Significant sagittal FO was noted in the stenosis males (L2-3 to L4-5) and females (L2-3 to L5-S1) compared to the controls. The prevalence of FT was remarkably greater in the stenosis males (L4-5, L5-S1) and females (L3-4, L5-S1) compared to their counterparts in the control group. Our results also showed that FT (L3-4 to L5-S1) increases approximately 2.9 times the likelihood for DLSS development. This study indicates that FO and FT in the lower lumbar spine are significantly associated with DLSS.

OBJECTIVE: This thesis aim to report the incidence of iatrogenic spinal instability that occurs after laminectomy, discectomy or facetectomy in Lumbar spine surgery. METHODS: This is a prospective study of 50 cases of degenerative lumbar spondylosis complaining of various symptoms of claudication, sciatica and back pain which were surgically managed by laminectomy according to the level of stenosis in the period between October 2018 and October 2020 in the neurosurgery department at Cairo university hospitals. Mesial facetectomy was added according to the degree of stenosis if needed. Some patients needed discectomy if sciatica was an eminent symptom. RESULTS: Out of 50 patients included: 9 patients (18%) developed postoperative instability. The number of levels operated on and the degree of mesial facetectomy were found to be variables that may affect postoperative stability. CONCLUSION: Iatrogenic instability may result from large laminectomy and extensive facetectomy for lumbar stenosis in patients who do not have obvious pre-existing instability. Key words: Iatrogenic spinal instability - Laminectomy - conventional open discectomy - Mesial facetectomy.

Abstract Background: Osteopetrosis is a group of rare inherited skeletal dysplasias, with each variant sharing the hallmark of increased bone mineral density (BMD). Abnormal osteoclast activity produces overly dense bone predisposing to fracture and skeletal deformities. Whilst no cure for these disorders exists, endocrinologists play an important role in surveillance and management of complications. Clinical Cases: A 43-year-old female had findings suggestive of increased BMD on radiographic imaging performed to investigate shoulder and back pain. X-ray of lumbar spine demonstrated a ‘rugger jersey’ spine appearance, while shoulder X-ray revealed mixed lucency and sclerosis of the humeral head. DXA scan showed T-scores of +11 at the hip and +12.5 at the lumbar spine. MRI of head displayed bilateral narrowing and elongation of the internal acoustic meatus and narrowing of the orbital foramina. Genetic assessment confirmed autosomal dominant osteopetrosis with a CLCN7 variant. Oral colecalciferol supplementation was commenced and multi-disciplinary management instigated with referral to ophthalmology and ENT teams. A 25-year-old male presented with a seven-year history of low back pain and prominent bony swelling around the tibial tuberosities and nape of neck. Past medical history included repeated left scaphoid fracture in 2008 and 2018. Recovery from his scaphoid fracture was complicated by non-union requiring bone grafting with open reduction and fixation. Plain X-rays of the spine again demonstrated ‘rugger jersey’ spine. DXA scan was notable for elevated T scores; +2.9 at hip and +5.8 lumbar spine. MRI spine showed vertebral endplate cortical thickening and sclerosis at multiple levels. The patient declined genetic testing and is under clinical review. A 62-year-old male was referred to the bone metabolism service following a DXA scan showing T scores of +11. 7 at the hip and +13 at the lumbar spine. His primary complaint was of neck pain and on MRI there was multi-level nerve root impingement secondary to facet joint hypertrophy. Past medical history was significant for a long history of widespread joint pains; previous X-ray reports described generalized bony sclerosis up to 11 years previously. Clinical and radiological monitoring continues. Conclusion: Individuals with osteopetrosis require a multidisciplinary approach to management. There is no curative treatment and mainstay of therapy is supportive with active surveillance for complications.

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.
