Abstract

The problem of low back pain (LBP) in children is very common and many specialists are dealing with it in everyday practice. The cause for low back pain often is not found and classified under the diagnosis of non specific low back pain. The objective of this prospective study is to determine wether children with non specific low back pain and existence of anomalies in LS spine (transitional vertebra- TV and/or Spina bifida occulta SBO) also have the degeneration of the intervertebral disc (DD) L4-L5 and/or L5-S1. This prospective study included 69 patients from 8 to 16 years of age (X 12.81) of whom 40 were male (57.97%), and 29 female (42.03%). They all were examinated in University of Zagreb, »Sestre milosrdnice« University Hospital Center, Zagreb Children’s Hospital, Department of Orthopaedic, Zagreb, Croatia. The reason of their visit was non specific low back pain. Pain was measured by visual analog scale (VAS) and mean score was three, duration of pain was between two and four weeks. Also, pain was sporadic, during daytime and not connected with level of physical activity. They all have undergone an algorithm of radiological examinations. Standard AP and LL radiographs (RTG) were made, as well as magnetic resonance (MR) of LS spine and sacrum in sagittal and transversal plane in T1 and T2 weighted sequence. The anomalies of L5 and S1 were found in 65 patients: transitional vertebra classified according to Castellvi et al. and SBO. In MRI in T2 weighted sequence DD was found in 61 patients which was classified modified from Pearce. Data analysis and comparison showed that 56 patients with TV and/or SBO have changes on vertebral dynamic segment L5-S1 (VDS) and that means DD. In 13 patients only DD or spinal anomaly (TV and/or SBO) were found. Correlation between anomalies and DD in those patients was established by McNemar analysis and has shown significant difference (p=0.581) in favour of the patients with anomaly and DD. This has established that all of 56 patients with spinal anomaly could have DD as known cause of LBP.
