Management of Lumbar Conditions in the Elite Athlete

Lumbar Spine Injuries in Recreational Athletes: A Review

Back pain that is associated with lumbar spine pathology is a growing issue in the athlete population. As an aging population continues to remain active, it is essential for primary care physicians, general orthopaedic surgeons, and spine surgeons alike to understand the nuances of diagnosis and management in the recreational athlete population. This is a unique population due to the increased importance placed on returning to high levels of activity, but, by definition, they enjoy less resources and financial incentive to optimize their rehabilitation and return to sport compared with professional athletes. Lumbar disk herniation, spondylolysis, and disk degeneration are common pathologies in this population. Most the time, these pathologies in recreational athletes can be managed nonsurgically with excellent outcomes. In recreational athletes who have failed nonsurgical treatment and/or have risk of neurological injury, surgical treatment is a viable option with good outcomes. Evidence suggests that most athletes can return to sport after both nonsurgical or surgical management. A rapidly expanding number of easily accessible, minimally invasive, surgical options continue to gain popularity and may gain further indication in this population. Future studies focused on the return to activity for the unique population of recreational athletes is warranted.

Long-term results and surgical strategy development for degenerative disease treatment in athletes: a retrospective single-center study

PURPOSE

To analyze of the results of spine surgical treatment of athletes with lumbar degenerative disease and development of a surgical strategy based on the preoperative symptoms and radiological changes in the lumbar spine.

METHODS

For 114 athletes with lumbar degenerative disease were included in the present study. Four independent groups were studied: (1) microsurgical/endoscopic discectomy (n = 35); (2) PRP therapy in facet joints (n = 41); (3) total disc replacement (n = 11); (4) lumbar interbody fusion (n = 27). We evaluated postoperative clinical outcomes and preoperative radiological results. The average postoperative follow-up was 5 (3;6), 3.5 (3;5), 3 (2;4) and 4 (3;5) years, respectively. The analysis included an assessment of clinical outcomes (initial clinical symptoms, chronic pain syndrome level according to the VAS, quality of life according to the SF-36 questionnaire, degree of tolerance to physical activity according to the subjective Borg Rating of Perceived Exertion Scale) and radiological data (Dynamic Slip, Dynamic Segmental Angle, degenerative changes in the facet joint according to the Fujiwara classification and disc according to the Pfirrmann classification; changes in the diffusion coefficient using diffusion-weighted MRI).

RESULTS

The median and 25-75% quartiles timing of return to sports were 12.6 (10.2;14.1), 2.8 (2.4;3.7), 9 (6;12), and 14 (9;17) weeks, respectively. We examined the type of surgical treatment utilized, as well as the preoperative clinical symptoms, severity of degenerative changes in the intervertebral disc and facet joint, the timing of return to sports, the level of pain syndrome, the quality of life according to SF-36, and the degree of tolerance to physical activity. We then developed a surgical strategy based on individual preoperative neurological function and lumbar morphological changes.

CONCLUSIONS

In this retrospective study, we report clinical results of four treatment options of lumbar spine degenerative disease in athletes. The use of developed patient selection criteria for the analyzed surgical techniques is aimed at minimizing return-to-play times.

Epidemiology of Lumbar Degenerative Phenotypes of Children and Adolescents: A Large-Scale Imaging Study

STUDY DESIGN

Cross-sectional study.

OBJECTIVE

Recently, there has been a rise in children and adolescents developing low back pain and/or sciatica. Degenerative lumbar spine MRI phenotypes can occur in this population but reports have been sporadic and the true incidence of such spine changes remains debatable. As such, the study aimed to address the epidemiology of MRI phenotypes of the lumbar spine in this young population.

METHODS

597 children and adolescents with lumbar MRIs were included in the study. T1- and T2-weighted lumbar images from L1/2 to L5/S1 were analyzed in axial and sagittal planes. Global phenotype assessment was performed of each level and based on established nomenclature protocols.

RESULTS

The cohort consisted of 57.3% (342) boys and 42.7% (255) girls, with a mean age of 10.75 ± 5.25 years (range: 0 to 18 years). The prevalence of imaging findings of lumbar disc degeneration (LDD) and lumbar disc herniation (LDH) were 2.2% (95% CI: 0.93-3.43) and 5.8% (95%CI: 2.58-8.99), respectively. There was significant difference between each disc segment from L1/2 to L5/S1 for both LDD and LDH. Schmorl's nodes were noted in 16 cases (2.7%, youngest case as 15 years), with 11 boys (68.8%) and most frequent segment as L3/4. Modic changes and high-intensity zones were absent in this cohort.

CONCLUSIONS

LDD can emerge as early as the first decade of life with Schmorl's nodes, without additional specific phenotypes, including Modic changes and high-intensity zones. The study provides valuable information of a unique age group that is often under-represented but equally important as adults.

Incidence and temporal changes in lumbar degeneration and low back pain in child and adolescent weightlifters: A prospective 5-year cohort study

This study was conducted to investigate the incidence of lumbar degeneration findings and low back pain (LBP) in children and adolescent weightlifters using magnetic resonance imaging (MRI) and medical questionnaires over a 5-year period. Moreover, we aimed to reveal the temporal changes in the lumbar vertebrae caused by long-term weightlifting training during the growth period. Twelve children and adolescent weightlifters who participated in weightlifting for >2 years (six boys, six girls, 11.4±2.0 years) were enrolled. Participants underwent annual medical questionnaire surveys, including data on practice frequency, competition history, presence of LBP, and lumbar examinations using MRI during the 5-year follow-up. Lumbar disc degeneration was detected in all the participants after 4 years, and lumbar disc herniation findings were detected in 33% of participants after 5 years; one underwent herniotomy during the follow-up period. Lumbar spondylolysis was detected in 58% of patients at 5 years. Although there were three participants who had LBP in the final year, none had LBP that prevented them from returning to weightlifting. This 5-year cohort study of 12 children and adolescent weightlifters detected lumbar degeneration in all participants. High frequency weightlifting training over a long period during the growth period may increase the risk of developing current and future LBP.

A randomized controlled trial concerning the implementation of the postural Mézières treatment in elite athletes with low back pain

OBJECTIVE

This study aimed to evaluate the impact of adding the Mézières Method (MM) to the standard rehabilitation protocol for the elite athletes with low back pain (LBP) in reducing lumbar pain than only using the traditional rehabilitation protocol treatment. The disciplines considered in this study were soccer, rhythmic gymnastics, and basketball.

DESIGN

Randomized controlled trial.

SETTING

Training Camp.

PARTICIPANTS

One hundred thirty-nine elite athletes with low back pain of whom 69 were assigned to the experimental group.

INTERVENTION

The intervention consists of treatment with three lying postures in a 40-minutes long session twice a week. The session goal was to focus on breathing exercises, spine mobility, and stretching of the back muscles, with particular attention to the diaphragmatic, paravertebral, and latissimus dorsi muscles.

OUTCOME MEASURES

Assessments as Visual Analogue Scale (VAS), Sit and Reach flexibility test, Roland-Morris Questionnaire, and health status questionnaire (SF12) were used.

RESULTS

The evaluation of all outcomes in 4 measurement periods of the study (baseline, 4, 12, and 24 weeks) showed a significant difference between groups. Also, at the 6-month of the intervention, a significant difference in the means (SD) was observed in pain (VAS), back flexibility (Sit & Reach) and back disability (QRM) outcomes in favor of the experimental group with a medium-large effect size comparing with the control group.

CONCLUSION

The MM approach can also be applied in established conventional protocols to alleviate pain and functionality. The obtained results include improving the quality of life of the athletes and their physical and emotional states.

Clinical trial registration number ID: NCT03849053.

[Results of the study of functional recovery of professional athletes after minimally invasive lumbar fusion]

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.

Implementation of Percutaneous Transforaminal Endoscopic Discectomy in Competitive Elite Athletes With Lumbar Disc Herniation: Original Study and Review of the Literature

BACKGROUND

Lumbar disc herniation (LDH) represents a frequent clinical entity in athletes. Surgical treatment of LDH with endoscopic spine surgical techniques has been proposed as a feasible alternative in these patients.

PURPOSE

To study the particular outcomes of percutaneous transforaminal endoscopic discectomy (PTED) in competitive elite athletes with surgically treatable LDH.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

A total of 55 competitive elite athletes with diagnosed LDH based on clinical and radiologic criteria were enrolled in this prospectively designed study. All patients underwent successful PTED. Clinical evaluation was conducted with the well-established visual analog scale for lower limb and low back pain separately. The 36-Item Short Form Health Survey (SF-36) was implemented for health-related quality of life analysis. Patients were assessed preoperatively and at regular postoperative intervals: 6 weeks and 3, 6, and 12 months, as well as 2 years.

RESULTS

Operated levels were L3-L4 (5.5%), L4-L5 (69.1%), and L5-S1 (25.4%). No major perioperative complications were observed. All patients successfully reached the end of follow-up at 2 years. Both visual analog scale scores (lower limb and low back pain) showed clinically and statistically significant improvement at 6 weeks postoperatively, with subsequent minor improvement and stabilization. All recorded SF-36 parameters demonstrated major clinical amelioration at 6 weeks, with subsequent minor but constant statistically significant improvement until the end of follow-up. Comparative evaluation of the SF-36 revealed that the physical function, bodily pain, role-emotional, and mental health parameters showed quantitatively greater improvement in comparison with rest indices.

CONCLUSION

PTED constitutes a feasible and effective technique for surgical management of LDH in athletes, providing favorable outcomes in terms of postoperative pain and health-related quality of life. Proper performance of technique for specific cases of L5-S1 LDH may be more challenging, and these cases should be evaluated selectively for suitability for this procedure.

Axial Low Back Pain in Elite Athletes

Back pain in sport is a common complaint and seen by athletes, trainers, and treating physicians. Although there are a multitude of pain generators, mechanical sources are most common. Certain sports can lead to increased mechanical and axial loading, such as competitive weightlifting and football. Common mechanical causes of pain include disk herniation and spondylolysis. Patients typically respond to early identification and conservative treatment. In others, surgical intervention is required to provide stability and prevent long-term sequelae.

The Advent of Spinoplastics: Easing the Growing Global Disease Burden of Spinal Injury

Epidemiologic studies have demonstrated a growing global disease burden of pathologies affecting the vertebral column. Allograft or implant-based reconstruction and fusion surgeries have been the mainstay of treatment. The efficacy of various surgical methods and the reliability of instrumentation or implants to execute these surgeries continue to be debated in the literature. Advances such as the free-tissue transfer have improved postoperative measures; however, they add high operative risk. The advent of spinoplastics introduces a practical surgical model to augment these spinal surgeries using vascularized bone grafts. As this technique becomes more widespread, it can be utilized to ease the growing disease burden that spinal injury places on both patients and the health care system. Ultimately, it will ameliorate strains on health care resources, reduce health care costs, and improve patient outcomes and quality of life.

Treating low back pain in athletes: a systematic review with meta-analysis

OBJECTIVE

To summarise the evidence for non-pharmacological management of low back pain (LBP) in athletes, a common problem in sport that can negatively impact performance and contribute to early retirement.

DATA SOURCES

Five databases (EMBASE, Medline, CINAHL, Web of Science, Scopus) were searched from inception to September 2020. The main outcomes of interest were pain, disability and return to sport (RTS).

RESULTS

Among 1629 references, 14 randomised controlled trials (RCTs) involving 541 athletes were included. The trials had biases across multiple domains including performance, attrition and reporting. Treatments included exercise, biomechanical modifications and manual therapy. There were no trials evaluating the efficacy of surgery or injections. Exercise was the most frequently investigated treatment; no RTS data were reported for any exercise intervention. There was a reduction in pain and disability reported after all treatments.

CONCLUSIONS

While several treatments for LBP in athletes improved pain and function, it was unclear what the most effective treatments were, and for whom. Exercise approaches generally reduced pain and improved function in athletes with LBP, but the effect on RTS is unknown. No conclusions regarding the value of manual therapy (massage, spinal manipulation) or biomechanical modifications alone could be drawn because of insufficient evidence. High-quality RCTs are urgently needed to determine the effect of commonly used interventions in treating LBP in athletes.

Part II: Comparison of Crossfit-Related Injury Presenting to Sports Medicine Clinic by Sex and Age

OBJECTIVE

To examine CrossFit-related injuries based on sex and age.

DESIGN

Retrospective case series.

SETTING

A tertiary-level pediatric sports medicine clinic.

PARTICIPANTS

CrossFit athletes.

MAIN OUTCOME MEASURES

CrossFit-related injuries by sex (males vs females) and age groups (≤19 years vs >19 years) using a χ analysis with P = 0.05, odds ratio (OR), and 95% confidence interval (95% CI).

RESULTS

Among injured CrossFit athletes, female athletes sustained lower extremity injuries more frequently than male athletes (P = 0.011; OR, 2.65; 95% CI, 1.25-5.65). In observed CrossFit injuries, shoulder injuries were more frequently observed in male athletes compared with female athletes (P = 0.049; OR, 2.79; 95% CI, 0.98-7.95). Additionally, a greater proportion of CrossFit athletes aged 19 years and younger suffered trunk/spine injuries than those older than 19 years (P = 0.027; OR, 2.61; 95% CI, 1.10-6.21) in injured CrossFit athletes.

CONCLUSIONS

The current results indicated sex- and age-specific susceptibility to CrossFit-related injuries based on body parts and diagnoses. The presented information may be useful to develop a safer exercise program, especially for pediatric and adolescent CrossFit participants.

The Effectiveness of the Mézières Method in Elite Rhythmic Gymnastics Athletes With Low Back Pain: A Randomized Controlled Trial

CONTEXT

One of the main reasons why athletes with a high physical condition suffer from low back pain disease is because they often participate in sports that involve disc compression movements during flexion, lifting loads, or torsion movement.

OBJECTIVES

This study aims to examine the effectiveness of the postural treatment of the Mézières method on elite rhythmic gymnastics athletes with low back pain.

DESIGN

Double-blind, randomized, controlled trial.

SETTING

The sports hall of "Puente Tocinos," Murcia, Spain.

PARTICIPANTS

Ninety gymnastics athletes were randomized into 2 parallel groups (intervention: n = 39; control: n = 51), of whom 98.9% were women (women = 89; man = 1).

INTERVENTION

The Mézières method postural therapy was implemented. It lasted about 60 minutes in repeated sessions of 2 to 3 meetings per week by counting in overall 60 sessions during a 24-week period.

MAIN OUTCOME MEASURES

Visual analog scale of pain, sit and reach flexibility test, Runtastic (pedometer performance android application), Roland-Morris Questionnaire for the physical disability, and the Health Status Questionnaire were used.

RESULTS

The univariate analysis of variance and independent sample t test revealed a significant improvement in the intervention group concerning the visual analog scale pain assessment scale (P < .05, ηp2=.625), and, also, the between-groups effect size was high during the 24 sessions of treatment (d > 0.8) compared with the control one. The same situation persists even for Roland-Morris Questionnaire (P < .05, ηp2=.802), physical score (P < .05, ηp2=.613), mental score (P < .05, ηp2=.736), sit and reach flexibility test (P < .05, ηp2=.666), and Runtastic performance (P < .05, ηp2=.790), where the between-groups effect size was high during the 24 sessions of treatment (d > 0.8).

CONCLUSION

The Mézières method treatment performed on athletes with low back pain has caused positive effects on all the outcomes analyzed compared with the ones of control group.

Injectable Corticosteroids in Sport

OBJECTIVE

To review the literature guiding all aspects of the use of injectable corticosteroids for painful musculoskeletal conditions, with a focus on the treatment of athletes.

DATA SOURCES

An extensive search of the literature was completed including search terms of corticosteroid, steroid, athlete, and injection, among others. Additional articles were used after being identified from previously reviewed articles.

MAIN RESULTS

Injections of corticosteroids for a variety of painful conditions of the extremities and the axial spine have been described. Numerous minor and major complications have been reported, including those with a high degree of morbidity. There is a dearth of published research on the use of corticosteroid injections in athletes, with most of the research on this topic focused on older, nonathlete populations. Generally, these injections are well tolerated and can provide short-term pain improvement with little or no long-term benefits.

CONCLUSIONS

Corticosteroid injections should be used cautiously in athletes and only after a full consideration of the pharmacology, pathogenesis of disease, potential benefits, complications, factors specific to the athlete, and rules of athletic governing bodies. Corticosteroid injections are just one component of a comprehensive rehabilitation plan available to the physician providing care to athletes.
