Suitability of 3.5-mm screw for the atlas in children: a retrospective computed tomography analysis.
The growth and development of the atlas in children has not been studied to date using a large sample size. ⋯ CT examination could help in preoperative decision-making, and 3.5-mm screw was found to be suitable for lateral mass screw internal fixation in children aging 2 years and older. D1-D4 increased with age. This provided a certain reference to perform posterior atlantoaxial fusion in children and is of great significance to design posterior atlantoaxial screw in children.

It's a long-held belief that Modic changes (MC) occur only in adults, with advanced age, and are highly associated with pain and adverse outcomes. The following study addressed the epidemiology, risk factors and clinical relevance of MC in young paediatric patients. ⋯ Contrary to traditional dogma, robust evidence now exists noting that MCs and their types can develop in children. Our findings give credence to the "Juvenile" variant of MCs, whereby its implications throughout the lifespan need to be assessed. Juvenile MCs have prolonged symptoms and related to specific structural spine phenotypes.

The specific radiological feature of osteoporotic vertebral compression fractures (OVCFs) is bone marrow oedema (BME) on magnetic resonance imaging (MRI). However, the relationship between BME and back pain (BP) is unclear. We investigated the value of MRI in assessing BP and discussed the relevant mechanisms by tissue biopsy. ⋯ BME signals on MRI can accurately predict the degree of BP, and the main mechanisms are related to the stimulation of fibrous tissue.

This study aimed to establish an animal model in which we can precisely displace the spinal cord and therefore mimic the chronic spinal compression of cervical spondylotic myelopathy. ⋯ Our implantable and wireless intervertebral compression model demonstrated outstanding controllability and reproducibility in simulating chronic cervical spinal cord compression in animals.
