Ossification of ligamentum flavum (LF) is a pathological condition that causes neurological symptoms and usually occurs in the thoracic spine and less frequently in the cervical spine. Symptomatology usually involves occipital headache in the early stage, neck pain and later sensory disturbances of upper and lower extremities, gait disturbance, restricted cervical movement and tetraparesis. Herewith, we report on 3 cases of ossification of the LF in the cervical and thoracic spine that had a favourable outcome after surgical treatment.

A patient in his early adolescence, who was treated for T5-T6 tubercular spondylodiscitis with an un-instrumented decompression, presented at 36 months post-index surgery, for post-laminectomy instability and kyphosis, after completing his requisite antitubercular treatment. He underwent thoracic posterior instrumented kyphosis correction and anterior reconstruction, with a T5-T6 partial corpectomy and corpectomy spacer placement, through a posterior midline incision. On the second postoperative day, he started complaining of pain on the left side of his chest, abdomen and left shoulder.

: The purpose of this study was to quantify the impact of smartphone use while sitting on the toilet on the spinal flexion angles and the time effect. : Measurements of the spinal flexion angles in the sagittal plane were made by thirty participants while they sat on the toilet for 10 min, using a smartphone in either one, both, or neither hand. The individual's forehead, cervical, thoracic and lumbar spinal areas were each fitted with five different inertial motion sensors.

Background: Previous studies have reported normative data for sagittal spinal alignment in asymptomatic adults. The sagittal spinal alignment change in European children was recently reported. However, there is a lack of studies on the normative reference values of sagittal spinal and pelvic alignment and how these parameters change at different growth stages in Chinese children.

The posterior ligamentous complex (PLC) provides critical structural support in the thoracolumbar spine. Its role in resisting progressive flexion is particularly important at the thoracolumbar junction due to the transition from the rigid thoracic spine to the more mobile lumbar region. Each component of the PLC contains anatomic features that contribute to both the structure and function of the PLC as a whole.
