    Quick Answers

    When to suspect spondylolysis in an adolescent athlete?
    It should be suspected in any adolescent with **low back pain persisting beyond 2-3 weeks** practicing sports with repetitive hyperextension (gymnastics, dance, diving, some roles in football and rugby). Pain is typically mechanical, worsens with hyperextension and eases with rest. Diagnosis is set up at the visit by combining history and clinical assessment.
    Does spondylolisthesis always worsen?
    No. Most **mild spondylolistheses** remain stable after the end of growth. Risk of progression is greater in some conditions (female sex, certain local anatomical features, already marked slip, rapid pubertal growth phase). For this reason periodic follow-up is generally proposed until skeletal maturity is reached.

    Spondylolysis is a defect of the vertebral pars interarticularis (most often at the lower lumbar level), typical of adolescent athletes engaged in activities with repetitive lumbar hyperextension (artistic gymnastics, dance, diving, specific roles in soccer and rugby). It may represent an active stress lesion, more likely to heal biologically, or a chronic established defect, which can persist without necessarily causing ongoing symptoms. It is relatively common in the general population, but clearly more frequent in adolescent athletes with persistent low back pain. When the lysis is bilateral it can progress to isthmic spondylolisthesis, an anterior slippage of the upper vertebra of variable degree. Typical symptoms include mechanical low back pain that worsens with hyperextension and improves with rest; in more advanced cases hamstring tightness, gait changes, or radiating lower-limb symptoms may appear. The diagnostic pathway is based on clinical assessment and, when indicated, targeted imaging, which also helps distinguish an active lesion from a chronic defect. Care is mainly conservative, individualized to the type of lesion: activity modification guided by symptoms, bracing considered case by case in select acute forms, and stabilization physiotherapy. Return to sport is guided by pain, function and clinical recovery rather than a fixed calendar, and in chronic defects does not necessarily require complete radiographic healing. Surgery is reserved for selected cases with progressive significant slippage or symptoms resistant to conservative care.

    Assessment and treatment

    When to seek evaluation

    • Persistent low back pain in an adolescent athlete (>2-3 weeks)
    • Low back pain that worsens with hyperextension
    • Practice of sports with repetitive hyperextension (gymnastics, dance, diving)
    • Hamstring tightness with limited forward bending
    • Postural changes (hyperlordosis, short-step gait)
    • Radiating lower-limb symptoms

    What is evaluated

    • History of sports activity and training load
    • Lumbar and lower limb neurological examination
    • Clinical maneuvers to reproduce pain in hyperextension
    • Hamstring and core flexibility assessment
    • Targeted radiographic imaging when clinically indicated
    • MRI in selected cases to assess pars bone edema

    Treatment options

    • Activity modification guided by symptoms, not a fixed duration
    • Bracing considered case by case in selected acute forms
    • Lumbopelvic stabilization physiotherapy and targeted stretching
    • Pain management in the acute phase
    • Return to sport guided by pain, function and clinical recovery
    • Referral to a dedicated paediatric spine surgeon in selected cases

    Frequently Asked Questions

    When to suspect spondylolysis in an adolescent athlete?▼
    It should be suspected in any adolescent with **low back pain persisting beyond 2-3 weeks** practicing sports with repetitive hyperextension (gymnastics, dance, diving, some roles in football and rugby). Pain is typically mechanical, worsens with hyperextension and eases with rest. Diagnosis is set up at the visit by combining history and clinical assessment.
    Does spondylolisthesis always worsen?▼
    No. Most **mild spondylolistheses** remain stable after the end of growth. Risk of progression is greater in some conditions (female sex, certain local anatomical features, already marked slip, rapid pubertal growth phase). For this reason periodic follow-up is generally proposed until skeletal maturity is reached.
    How long does the sports break last?▼
    There is no single fixed duration: timing depends on whether the lesion is an active stress reaction or an already chronic defect, on symptoms and on the sport practiced. Rather than a rigid suspension period, the approach is guided by pain disappearance and clinical response. Return is progressive: first low-impact aerobic activities, then core strengthening, finally sport-specific gestures. In chronic defects, complete radiographic healing is not always necessary before a functional return is considered.
    When is surgery considered?▼
    Surgery is considered in selected cases: slips that progress over time, significant forms with major symptoms, radiating symptoms resistant to a well-conducted conservative pathway, disabling low back pain persisting despite adequate therapy. In these situations the role of the visit is to recognise referral criteria and direct the family to a dedicated paediatric spine surgeon or specialist centre, which will discuss technique and timing.
    Can competitive sport be resumed after recovery?▼
    Yes, in most cases. After good clinical response and a well-conducted core rehabilitation program, the **athlete can return to competitive sport**, even in sports involving hyperextension. In stable mild spondylolistheses sport is generally allowed; in more complex cases the decision is taken case by case.
