Medicine (Baltimore) 2023; 102:e34857. [PMID: 37747004 PMCID: PMC10519456 DOI: 10.1097/md.0000000000034857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 07/27/2023] [Accepted: 07/31/2023] [Indexed: 09/26/2023] Open
Abstract
BACKGROUND Low back pain (LBP) is a common chief complaint from athletes. Lumbar spondylolysis (LS) is a common sport injury. Severe LS is likely to cause spinal instability, resulting in lumbar spondylolisthesis or lumbar disc herniation, and even damage to the spinal nerve roots. The incidence of LS is approximately 5% in the adult population, and nearly half of young athletes with LBP are diagnosed with LS. This meta-analysis analyzed the incidence of LS in athletes with LBP. METHODS PubMed, Embase, Cochrane (Cochrane Central Register of Controlled Trials), and Web of Science databases were systematically searched for published case report and retrospective analyses related to the topic from the date of database creation to January 1,2023. Relevant literature was screened and information extracted, and risk of bias was assessed for included studies using the methodological index for non-randomized-studies scale. Single-arm Meta-analysis was performed using R4.04 software. Heterogeneity was quantified by Cochran Q test and Higgins I2. Funnel plots were used to visualize publication bias, and Egger test and Begg test were used to statistical tests. RESULTS A total of 9 studies (835 patients) were included in this study. Meta-analysis revealed that the prevalence of LS in athletes with LBP was estimated at 41.7%, [95% CI = (0.28-0.55)], but this prevalence varied considerably with the gender and age of the athletes. CONCLUSION The estimated prevalence of LS in athletes with LBP is 41.7%, and future correlations between the prevalence of LS in adolescent athletes worldwide need to be assessed from different perspectives, including biomechanical, hormonal, anatomical, behavioral, and gender differences.

Abstract
Intervertebral disc degeneration (IDD) and osteoarthritis (OA) affecting the facet joint of the spine are biomechanically interdependent, typically occur in tandem, and have considerable epidemiological and pathophysiological overlap. Historically, the distinctions between these degenerative diseases have been emphasized. Therefore, research in the two fields often occurs independently without adequate consideration of the co-dependence of the two sites, which reside within the same functional spinal unit. Emerging evidence from animal models of spine degeneration highlight the interdependence of IDD and facet joint OA, warranting a review of the parallels between these two degenerative phenomena for the benefit of both clinicians and research scientists. This Review discusses the pathophysiological aspects of IDD and OA, with an emphasis on tissue, cellular and molecular pathways of degeneration. Although the intervertebral disc and synovial facet joint are biologically distinct structures that are amenable to reductive scientific consideration, substantial overlap exists between the molecular pathways and processes of degeneration (including cartilage destruction, extracellular matrix degeneration and osteophyte formation) that occur at these sites. Thus, researchers, clinicians, advocates and policy-makers should consider viewing the burden and management of spinal degeneration holistically as part of the OA disease continuum.

Abstract
Background The aim of the study was to assess the prevalence of back pain in non-professional Brazilian Jiu-Jitsu practitioners (NP-BJJ practitioners), and to assess the relationship between their back pain and postural disorders. Methods The study involved 61 subjects (age: 30.7 ± 4.9 years old; body mass: 79.4 ± 12.9 kg; body height: 179.6 ± 8.4 cm; 8 woman and 53 man), 31 who trained Brazilian Jiu-Jitsu (BJJ) and 30 subjects who had never trained any combat sport. The mean time of training BJJ in the study population was 3.9 ± 4.1 years. Postural assessments were conducted with the use of the photogrammetric method. The assessment of back pain and injuries was conducted with the Oswestry Disability Index (ODI) and with our proprietary questionnaire. Results Among both populations, 37 subjects reported back pain. There were no differences in back pain location between the two groups or in functional state on the ODI. Significant differences between the groups in the values of the postural parameters (spinal height, length of kyphosis, length of lordosis, pelvis inclination angle) were observed. Statistically significant differences between the NP-BJJ practitioners with and without back pain in the length of the thoracic kyphosis and the differences in the height of the waist triangles were found. Conclusions Both in the study population and in the control group the spinal pain was minimal or moderate on the ODI. BJJ practitioners who reported back pain had characteristic postural changes in some of the analysed postural parameters in comparison to BJJ practitioners who did not report back pain.

Abstract
Non-specific low back pain in athletes can be caused by discogenic back pain, Modic type 1 change, and facet joint arthritis. In this report, we describe a full-endoscopic surgical strategy that we have used to treat a patient with both discogenic pain and Modic type 1 change. The patient was a 32-year-old professional baseball player who played an infield position and had a 2-year history of low back pain. Three years earlier, he had undergone micro-endoscopic discectomy for left herniated nucleus pulposus at L5/S1. His leg symptoms resolved postoperatively, and he returned to playing baseball the following season. However, his low back pain gradually increased. Two years after the initial surgery, he was experiencing low back pain in daily life and found it very difficult to play baseball. Short T1 inversion recovery (STIR) magnetic resonance imaging (MRI) revealed Modic type 1 change and high-signal intensity zones in degenerated discs at L4/5 and L5/S1. Injection of xylocaine 1% reduced the pain temporarily, confirming that the pain generator was at L4/5 and L5/S1. The pathological diagnosis was discogenic pain with Modic type 1 change. We performed full-endoscopic disc cleaning (FEDC) surgery for the Modic type 1 change and thermal annuloplasty (TA) for the discogenic pain at these levels. The patient's low back pain decreased steadily thereafter. Six months after surgery, he returned to baseball, playing for a full season without pain. We have successfully treated a professional baseball player with discogenic pain and Modic type 1 change by full-endoscopic surgery.

Abstract
OBJECTIVE To conduct a comprehensive clinical-neurological assessment and to study the results of functional recovery of professional athletes after minimally invasive lumbar interbody fusion. MATERIALS AND METHODS The retrospective study included 27 patients-professional athletes who were operated on using minimally invasive decompression and stabilization techniques in the period 2010 to 2019. Clinical-neurological effectiveness was assessed when returning to previous sports activity was 14 (9; 17) weeks and 4 (3; 5) years after surgery. RESULTS The follow-up showed a significant improvement in clinical and neurological parameters: persistent elimination of radicular and muscular-skeletal symptoms, a decrease in the level of pain according to a visual analogue scale in the lumbar spine from 68 (61; 85) mm to 3 (2; 11) mm (p=0.002) and in the lower extremities from 84 (78; 91) mm to 1 (0; 3) mm (p=0.001), change in the physical component of health from 26.18 (23.58; 28.37) to 49.82 (49.03; 53.04) (p=0.002) and the psychological component of health from 27.87 (26.22; 29.29) to 52.18 (49.12; 55.66) (p=0.001), significant improvement in the perception of physical activity according to the Borg RPE Scale from 17 (16; 18) points to 9 (8; 9) (p<0.001). In one case (3.7%), the patient did not return to his previous sports career. CONCLUSION The use of minimally invasive rigid stabilization in the overwhelming majority of professional athletes made it possible in the shortest possible time to achieve regression of neurological symptoms, reduce pain, improve the quality of life, restore the functional state and return to previous sports activities.

Abstract
Professional athletes have a high basic level of physical fitness and significant motivation for returning to previous rhythm of functional activity within the shortest period after trauma without deterioration of baseline level of sportsmanship. Despite the well-presented results of lumbar spine fusion in general population, these data among professional athletes are not well understood. OBJECTIVE To analyze the results of minimally invasive lumbar fusion in professional athletes. MATERIAL AND METHODS A retrospective study included 27 athletes (19 men and 8 women) aged 29 (26; 34) years after minimally invasive lumbar spine decompression and fusion via anterior, lateral and posterior approaches. Total lumbar lordosis, degenerative changes in adjacent segment, area of multifidus muscle, perioperative complications and timing of sports rehabilitation were analyzed within 3-5 (mean 4) years after surgery. RESULTS We found an increase of total lumbar lordosis from 35.2° to 44.1° (p=0.02), no significant muscle atrophy (<30%) and degeneration of adjacent segment (p>0.05). There were 5 perioperative complications (18.5%). Mean period of sports rehabilitation was 14 (9; 17) weeks. One (3.7%) patient did not return to his previous sports career. CONCLUSION Minimally invasive short-segment lumbar interbody fusion in professional athletes is characterized by low risk of fixation element failure, no significant degeneration of adjacent level and postoperative muscle atrophy. This procedure ensures early rehabilitation and returning to sports.

Abstract
OBJECTIVE To analyze the clinical and biomechanical outcome of professional athletes after lumbar total disk replacement, with a focus on restoration of the functional activity. METHODS This nonrandomized retrospective single-center study included 11 professional athletes who underwent lumbar disc replacement surgery using the prosthesis M6-L (Spinal Kinetics, Schaffhausen, Switzerland). The average postoperative follow-up was 3.18 ± 1.14 years. The following outcomes were evaluated: intensity of pain in the lumbar spine and lower limbs, Oswestry Disability Index, Short-Form 36, complications, time of return to previous sports activity, range of movement, degree of lumbar lordosis, degenerative changes of the adjacent levels, and degree of heterotopic ossification. RESULTS The operated patients reported significant decrease of pain on visual analog scale (P < 0.001) as well as significant improvement of Oswestry Disability Index (P = 0.001) and Short-Form 36 (P < 0.001). For the duration of follow-up, the patients maintained segmental range of motion at L4-L5 (P = 0.04) and L5-S1 (P = 0.03) levels. There was also some statistically insignificant increase of global lumbar lordosis (P = 0.84). We did not identify any significant degeneration of the adjacent intervertebral disks (P > 0.05) or progression of the facet joint degenerative changes at the implantation level and in the adjacent segments (P > 0.05). One patient (9.1%) developed grade I heterotopic ossification 5 years after surgery and in 1 patient (9.1%), a lesion of superior hypogastric plexus was recorded. The average time of return to previous sports activity was 9.72 ± 3.03 weeks. CONCLUSIONS Total lumbar disc replacement using M6-L prosthesis in professional athletes made it possible to achieve statistically significant reduction of pain and facilitated early return to normal sports activities. In our opinion, preservation of movement of the operated lumbar segment can help to reduce the mechanical stress with beneficial impact on the rate of degeneration of the adjacent level.

Orthop J Sports Med 2021; 9:2325967121995466. [PMID: 33889645 PMCID: PMC8040580 DOI: 10.1177/2325967121995466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Accepted: 12/14/2020] [Indexed: 11/15/2022] Open
Abstract
Background: Spondylolysis and undiagnosed mechanical low back pain (UMLBP) are the main causes of low back pain (LBP) in adolescent athletes. No studies have evaluated the difference in clinical and radiographic factors between these 2 conditions. Furthermore, it remains unclear which adolescent athletes with LBP should undergo advanced imaging examination for spondylolysis. Purpose: To compare the clinical and radiographic factors of adolescent athletes with spondylolysis and UMLBP who did not have neurological symptoms or findings before magnetic resonance imaging (MRI) evaluation and to determine the predictors of spondylolysis findings on MRI. Study Design: Cohort study, Level of evidence, 3. Methods: The study population included 122 adolescent athletes aged 11 to 18 years who had LBP without neurological symptoms or findings and who underwent MRI. Of these participants, 75 were ultimately diagnosed with spondylolysis, and 47 were diagnosed with UMLBP. Clinical factors and the following radiographic parameters were compared between the 2 groups: spina bifida occulta, lumbar lordosis (LL) angle, and the ratio of the interfacet distance of L1 to that of L5 (L1:L5 ratio, %). A logistic regression analysis was performed to evaluate independent predictors of spondylolysis on MRI scans. Results: Significantly more athletes with spondylolysis were male (82.7% vs 48.9%; P < .001), had a greater LL angle (22.8° ± 8.1° vs 19.3° ± 8.5°; P = .02), and had a higher L1:L5 ratio (67.4% ± 6.3% vs 63.4% ± 6.6%; P = .001) versus athletes with UMLBP. A multivariate analysis revealed that male sex (odds ratio [OR], 4.66; P < .001) and an L1:L5 ratio of >65% (OR, 3.48; P = .003) were independent predictors of positive findings of spondylolysis on MRI scans. Conclusion: The study findings indicated that sex and the L1:L5 ratio are important indicators for whether to perform MRI as an advanced imaging examination for adolescent athletes with LBP who have no neurological symptoms and findings.

Abstract
BACKGROUND Spondylolysis is the main cause of low back pain (LBP) in young athletes. There are few studies analyzing the difference of spondylolysis among young athletes with different sports activities. The purpose of this study was to compare the clinical factors and distribution of the lesions of spondylolysis on magnetic resonance imaging (MRI) scans in young soccer and baseball players with symptomatic spondylolysis. METHODS The medical records of 267 young athletes aged 7 to 18 years old who underwent MRI to evaluate the cause of LBP between 2017 and 2020 were retrospectively reviewed to identify patients with spondylolysis. Of the young athletes with symptomatic spondylolysis, clinical factors and MRI findings in soccer and baseball players were retrospectively evaluated. The clinical factors were age, sex, interval from onset of LBP to MRI, and side of the dominant leg in the sports field. MRI findings included number, lumbar level, and side of the lesions. RESULTS A total of 33 soccer players (mean age, 15.4 ± 1.4 years) and 49 baseball players (mean age, 15.4 ± 1.6 years) with symptomatic spondylolysis were enrolled. All patients were male. No significant differences were noted in age and the interval from onset of LBP to MRI between the groups. Soccer players had greater numbers of multiple (p < 0.001) and bilateral (p < 0.001) lesions than baseball players. The dominant side of the hand for pitching or batting was correlated with the contralateral-side lesions in baseball players (p = 0.001). CONCLUSIONS The distribution of the lesions of spondylolysis differed in young soccer and baseball players. Pitching or batting with the dominant-side hand would be associated with contralateral-side lesions in baseball players. Sports-specific movements and the side of the dominant leg should be considered when treating young athletes with symptomatic spondylolysis.
