The objective of this study were to: (i) describe the typical three-dimensional (3D) angular kinematics of the lumbar spine and pelvis during running and; (ii) assess whether the movements of the lumbar spine and pelvis during running are coordinated. A cohort of 20 non-injured male runners who usually ran >20 km/week were voluntarily recruited. All trials were conducted on a treadmill at a run...

The Anatomy of the Lumbar Vertebral Column T he lumbar portion of the vertebral column has an ideal structure aiming at maintaining stability and mobility. This region has a solid structure designed to carry the weights of the head, the neck, the trunk and the extremities. The pains associated with this region are very common complaints affecting 80% of the population at least one time during t...

PURPOSE The purpose of this study was to establish normative values for active lumbar movement in children five, seven, nine, and 11 years of age. METHODS End range active flexion, extension, and right- and left-side bending and rotation of the lumbar spine were measured for 225 normally developing children (116 girls, 109 boys) using the Back Range of Motion (BROM II) device. Means were dete...

As an essential organ of both weight bearing and locomotion, the spine is subject to the conflict of providing maximal stability while maintaining crucial mobility, in addition to maintaining the integrity of the neural structures. Comparative morphological adaptation of the lumbar spine of mammals, especially in respect to locomotion, has however received only limited scientific attention. Spe...

Introduction Spinal muscles transmit most of the kinematical forces to the spine tissues and therefore, careful modelling of muscle activity is critical for an adequate estimation of spinal loads. However, current lumbar spine numerical models overlook such muscle contribution or suggest simplifications that do not allow thorough studies of load transfers within the deforming spine. As such, th...

Bone localisations of amyloidosis are rare, usually diffuse and associated with myeloma. We report the case of a patient with massive obesity complicated by diabetes, hypertension, sleep apnea and liver steatosis, who complained of rapidly worsening bilateral polyradiculalgia of the lower limbs. After sufficient weight loss made nuclear magnetic resonance imaging feasible, a spinal tumour was v...
