Abstract Objectives To explore the features of high-intensity zone (HIZ) in anterior annulus fibrosus and assess the association of anterior HIZ with low back pain (LBP). Design, Setting, and Subjects A retrospective study of 5,940 discs in 1,188 individuals was conducted. Methods Subjects’ information and LBP symptoms confirmed by an orthopedic surgeon were acquired from the medical record. Magnetic resonance (MR) image reading and analysis were performed by two experienced blinded radiologists. Results Two hundred eighty individuals exhibited 355 anterior HIZs in 355 discs. The prevalence was 23.57%; 88.45% were located in the inferior part of the annulus fibrosus. It frequently occurred in the middle and upper segments of lumbar spine, especially at L3/4 (45.63%). Of the 355 anterior HIZs, only 79 (22.25%) were consecutive-slides HIZ. Round type (63.38%) was the most common shape of anterior HIZs. The highest prevalence was found in individuals aged 60–69 years. LBP was confirmed in 141 anterior-HIZ individuals. The incidence of LBP in anterior-HIZ individuals was significantly higher than in non-HIZ subjects (50.36% vs 35.24%, χ2 = 18.314, P < 0.001). Conclusions Anterior HIZ is a lower-prevalence, age-related sign on lumbar MR images. The spatial distribution of anterior HIZ can be distinguished from posterior HIZ. The number of consecutive anterior HIZ slides might suggest fewer Dallas grade 4 anterior annular disruptions in this sample. Anterior HIZ was correlated with LBP.

Purpose. To assess the correlation between low back pain and a high-intensity zone (HIZ) of the lumbar disc in Indian patients. Methods. 200 patients with low back and/or leg pain underwent magnetic resonance imaging of the lumbosacral spine. The location and severity of pain and disability were assessed using the pain drawing, visual analogue scale, and Oswestry Disability Index, respectively. The inter-observer reliability was assessed using the kappa statistic. Results. The prevalence of an HIZ was 13% and 17% according to observers A and B, respectively. The inter-observer reliability was fair (κ=0.64, p<0.005). The presence of an HIZ did not correlate with low back pain according to the pain drawing, visual analogue scale, and Oswestry Disability Index. According to the pain drawing data, the sensitivity, specificity, and positive predictive values of an HIZ to low back pain were 11%, 82%, and 62%, respectively. Conclusion. The presence of an HIZ is not diagnostic of a disrupted and painful disc, and should be interpreted together with other prevailing symptoms and clinical findings.

BACKGROUND: Chronic low back pain lasts longer than 12 weeks and is characterised by pain, muscle weakness, reduced functional ability and psychosocial burden. AIM: To compare the effects of two physical modalities, high-intensity laser against ultrasound therapy in the treatment of patients with chronic low back pain. MATERIAL AND METHODS: This was a prospective, monocentric, controlled clinical study comprising a group of 54 patients at the age between 25 and 65 years. Patients were divided into two groups: examined group of 27 patients (high-intensity laser and exercises) and a control group of 27 patients (ultrasound therapy and exercises). The results were evaluated by the Numeric Pain Rating Scale, Oswestry Disability Index and Schober’s test. Clinical findings were evaluated at the same time points for all patients, before treatment, at two weeks and three months following treatment. Statistical analyses were made to compare the differences between the results obtained on admission and the two consecutive control check-ups. Statistical significance was defined as a P value < 0.05. RESULTS: The examined group showed statistically significantly better results than the control group after completion of the treatment (at two weeks) and at follow up after three months. CONCLUSION: This study has shown that patient with chronic low back pain treated with a high-intensity laser has significantly reduced low back pain, reduced disability and improved range of motion. Its positive effect maintained for three months. It seems to be an effective, safe and useful physical modality in the treatment of a patient with chronic low back pain.
