Introduction: Low back pain (LBP) defined as ache or pain in the lowest part of the back is a common experience among people all over the world. The lifetime prevalence is reported to be as high as 84%, and the prevalence of LBP seems to be almost the same among adolescents as among adults. The risk for having LBP later in life if you experienced LBP in adolescence is high.

Material and Methods: In this cross‐sectional study of 2550 students aged 16‐20 years, we used the Standardized Nordic Questionnaire for the analysis of musculo‐skeletal symptoms. We studied gender difference, prevalence, and disability of Low back pain. We also studied differences in LBP in adolescent athletes depending on hours spent on sports or physical activity.

Results: Significantly, more girls than boys had had problems sometimes during their life. Those who participated in sports reported LBP to a significantly higher extent than those who were physically inactive in their spare time. Gender and spare time sports were important risk factors for getting LBP some time in life. There was a higher risk for girls to have low back pain problems more than 30 days or daily the last year if they had had low back pain some time earlier in life.

Conclusion: This study shows that low back pain (LBP) is common among Swedish adolescents, more common among girls than boys. High sport activity was associated with the risk of having LBP, length of time with LBP, and disability due to LBP.

Abstract [en]

Background: Globally Low back pain (LBP) is one of five leading causes of years lived with disability (YLD), and LBP is a common complaint among adults as well as adolescents and adolescence athletes. During adolescents, the LBP often is considered as non- specific without structural findings and thus not needed to be further diagnosed or treated specifically. However, LBP that begins in adolescence often continue through adulthood, and since adolescent athletes with high physical activity seems to have more LBP than less physically active adolescents, high physical loading during adolescence, might be a risk factor for LBP later in life.

Studies: Epidemiology: The Standardized Nordic Questionnaire adjusted for adolescence was used to investigate the prevalence of LBP during adolescence (16-19 years old individuals).

Retrospective study: A ten-year follow-up on symptomatic low back spondylolysis patients identified on MRI or CT. Sixteen out of nineteen identified patients agreed to answer a questionnaire and to have their case-history reviewed.

Case-control study: Twenty-five patients (13-19-year-old boys and girls) with LBP and 13 pain free individuals (controls, 14-19-year-old boys and girls) were investigated with physical examination and MRI. If the patients had findings on MRI a CT investigation was performed.

Clinical study: Twelve of 14 patients (a subgroup from the case-control study) with Spondylolysis on MRI and CT were evaluated with a modified Hollenberg classification (six levels). These patients were re-evaluated with MRI and CT after 3 months of treatment with complete rest from sports activity.

Differential diagnosis: Five adolescent patients with on-going LBP/thigh pain previously treated in other clinics, were reevaluated for a “second opinion”.

Results: Epidemiology study: The prevalence of LBP among adolescents was 46% (N= 2522) with an annual incidence of 42 %. Girls reported more LBP than boys (52 % versus 40 %). Individuals who were active in sports > 6 h/w had significantly more LBP compared with less physically active individuals. 

Retrospective study: Thirteen of the 16 individuals had a second MRI/CT investigation and thus 52 out of the initial 64 pars interarticularis where investigated a second time (mean 3 months after the first investigation). These patients had had different treatments, most commonly rest for 3 months. In total, 7 out of 16 individuals healed (44%).

Case control study: In 22/25 patients (88%) there were clinical findings and MRI findings such as spondylolysis, disc herniated discs, disc degeneration and injuries to the vertebral body. In 13/25 patients (52%) spondylolysis of different stages were found. No clinical test alone, or in combination, could reliably diagnose spondylolysis, and could thus not be used as a selection test for patients who need further diagnostics with MRI and CT.

Clinical study: Using a combination of MRI and CT examination the early signs of skeletal injury (oedema, incomplete fracture) to the pars interarticularis were detected. Patients diagnosed with these early stages healed significantly better than if diagnosed in later stages (complete fracture and pseudoarthrosis).

Differential diagnosis: The second opinion with careful physical examination and MRI examination diagnosed stress reactions in the pelvic ischial tuberosity in the patient seeking help for pain in the lower back/thigh. After guided rehabilitation, all these patients returned to previous sport activities.

Conclusions: LBP is common during adolescence, more common in girls and in highly active individuals. LBP must be taken seriously, especially in adolescent athletes who not seldom have fractures in pars interarticularis (Spondylolysis). If diagnosed early, there seems to be good potentials to heal the fracture with 3 months ́ of rest from loading (sport activity). Differential diagnoses such as stress reactions in the pelvic ischial tuberosity should be taken into consideration.
