Adolescent Disc Disease: Risk Factors and Treatment Success-Related Factors

Discectomy for Lumbar Disc Herniation in Pediatric and Adolescent Populations: A Systematic Review and Meta-Analysis

Corroborative evidence for discectomy in pediatric or adolescent patients remains scarce, with this single-arm meta-analysis investigating discectomy for lumbar disc herniation (LDH) within this population. PubMed, Embase (Elsevier), CiNAHL, Cochrane Library, Scopus, and Web of Science were searched. Eligible studies reported pediatric patients under 21 years of age with a diagnosis of LDH that was treated surgically with discectomy. This review was registered in PROSPERO (ID: CRD42023463358). Twenty-two studies met the eligibility criteria (n=1182). Visual analog scale (VAS) scores for back pain at baseline were 5.34 (95% CI: 4.48, 6.20, I2=98.9%). Postoperative VAS back pain scores after 12 months were 0.88 (95% CI: 0.57, 1.19, I2=95.6%). VAS scores for leg pain at baseline were 7.03 (95% CI: 6.63, 7.43, I2=93.5%). Postoperative VAS leg pain scores after 12 months were 1.02 (95% CI: 0.68, 1.36, I2=97.0%). Oswestry disability index (ODI) scores at baseline were 55.46 (95% CI: 43.69, 67.24, I2=99.9%). Postoperative ODI scores after 12 months were 7.82 (95% CI: 4.95, 10.69, I2=99.4%). VAS back, VAS leg and ODI scores demonstrated a minimum clinically important difference (MCID) at all postoperative points. Perioperative outcomes demonstrated operative time as 85.71 mins (95% CI: 73.96, 97.46, I2=99.4%) and hospital length of stay as 3.81 days (95% CI: 3.20, 4.41, I2=98.5%). The postoperative reoperation rate at the same level was 0.01 (95% CI: <0.00, 0.02, I2=0%). Discectomy appears safe and effective in pediatric and adolescent patients suffering from LDH. The findings here provide groundwork for future randomized control trials against conservative measures to elaborate on optimal management and elucidate long-term outcomes.

Age and Sex Differences in Pediatric Neuropathic Pain and Complex Regional Pain Syndrome: A Scoping Review

BACKGROUND

Age and sex differences may exist in the frequency (incidence, prevalence) or symptoms of neuropathic pain (NP) and complex regional pain syndrome (CRPS) due to biopsychosocial factors (eg, neurodevelopment, physiological and hormonal changes, psychosocial differences) that evolve through childhood and adolescence. Age and sex differences may have implications for evaluating screening and diagnostic tools and treatment interventions.

OBJECTIVE

To map the existing literature on pediatric NP and CRPS with respect to age and sex distributions, and age and sex differences in symptomology and frequency.

METHODS

A scoping literature review was conducted. Databases were searched from inception to January 2023. Data were collected on study design, setting, demographics, and age and sex differences in frequency and symptoms.

RESULTS

Eighty-seven studies were included. Distribution of participants with CRPS (n=37 studies) was predominantly early adolescence (10 to 14 y) and female sex, while NP (n=42 studies) was most commonly reported throughout adolescence (10 to 19 y) in both sexes. Forty-one studies examined age and sex differences in frequency; 6 studies reported higher frequency in adolescence. Very few studies (n=11) examined differences in symptomology.

DISCUSSION

Large epidemiological studies are required to further understand age and sex differences in frequency of pediatric NP and CRPS. Age and sex differences must be considered when evaluating screening and diagnostic tools and treatment interventions to ensure relevance and validity to both sexes and across ages. Validated tools will improve understanding of age-dependent and sex-dependent differences in symptoms, pathophysiology, and psychosocial impact of pediatric NP and CRPS.

Risk factors for lumbar disc herniation in adolescents and young adults: A case-control study

Background

There is a limited understanding of the risk factors for lumbar disc herniation (LDH) in younger people, even though the evidence suggests that LDH is more prevalent in this population. This study aimed to comprehensively analyze the risk factors for LDH in adolescents and young adults.

Methods

The medical records of all patients were retrospectively reviewed with inclusion criteria of being younger than 25 years. Magnetic resonance imaging (MRI) was used to confirm LDH from September 2016 to September 2021. Furthermore, 104 healthy people in the same age range were enrolled as the control group from physical examination centers. Gender, BMI, smoking, drinking, genetic history, sitting posture, daily sitting time, traumatic history of the lower back, scoliosis, and daily exercise time were examined for all enrolled people. These factors were statistically analyzed to determine the high-risk factors.

Results

A total of 208 young individuals were enrolled in the present study. The mean age of the study group and the control group was 21.06 ± 3.27 years (range: 11-25 years) and 21.26 ± 2.23 years (range: 15-25 years), respectively. The result of the chi-squared test demonstrated that there was a significant difference in BMI of more than 30 (p < 0.001), genetic history (p = 0.004), sitting posture (p < 0.001), daily sitting time of more than 6 h (p < 0.001), and the history of low back trauma (p = 0.002). Additionally, multivariate logistic regression showed that these were high-risk factors for LDH, particularly the duration of daily sitting time (more than 6 h).

Conclusions

BMI of more than 30, genetic history, sitting posture, daily sitting time of more than 6 h, and a history of low back trauma are the high-risk factors for adolescents and young adults with LDH. Therefore, providing them with the proper guidance and education, particularly about the protection of the lower back and the reduction of spinal load, could play a key role in preventing and reducing LDH.
