A cervical collar can be adjustable with respect to a wearer's head and neck, and include a back portion positionable posterior to a wearer's neck. The collar can also include a member that extends anteriorly relative to the back portion, and can have a mechanism adapted to reposition a prominence of the member superiorly, inferiorly, anteriorly, and posteriorly relative to the portion while the collar is installed on the wearer. A method of enforcing a lordotic curve in a wearer's cervical spine is also disclosed including installing a cervical collar on the wearer, adjusting the cervical collar to fit the wearer's head and neck, and positioning a member so that the member extends anteriorly with respect to the back portion to an extent that is independent of a tightness of the collar about the neck.

Spinal canal expansion through pedicle lengthening in combination with spinal column stabilization, to treat spinal stenosis, spondylolisthesis, kyphosis, scoliosis or a major spinal rotational deformity, with or without a spinal fusion. A device or implant that includes a pedicle lengthening implant to decompress (expand) the spinal canal, and a bridge to connect two or more pedicle lengthening implants and/or pedicle screws or bone anchors to achieve simultaneous spinal stabilization across one or more vertebral segments. The bridge across the vertebral segments can include a longitudinal member, such as a plate or rod. The pedicle lengthening implant is originally made, or can be modified to, connect to the longitudinal member. Spinal deformity can be manipulated, through operation of one or more pedicle lengthening implants in respective vertebral segments, to improve a relative relationship between the respective vertebra segments, the longitudinal member then fixating the vertebral segments into a multi-level spinal construct.

A traction device comprises a frame, a first bladder portion, a second bladder portion, a strap, and a pump. The first bladder expands in an outward direction a distance greater than in a transverse direction. The second bladder expands in an angular direction. The second bladder is positioned generally below and to the side of the first bladder. The frame is secured to the user's head. Upon expanding in the outward direction, the first bladder bears against the back of the user's neck and forces the cervical spine to curve forwardly. Upon expanding in the transverse direction, the first bladder applies an angular traction to the cervical spine. Upon expanding in the angular direction, the second bladder bears angularly against the back of the user's upper thoracic region and forces the thoracic spine to decompress and reduces hyper-kyphosis of the upper thoracic spine.

The present invention relates generally to a device of and a method for correcting spinal deformities, such as scoliosis and kyphosis. The invention employs the superelasticity or pseudoelasticity, such as found in a nickel-titanium alloy, to provide a continuous, predictable, and controllable correction force and to achieve a gradual and full correction. The correction force can be exerted on the deformed spine either at the time of the spine surgery or after the surgery or both, to afford a full or substantially full correction. The continuous and controllable correction force of the present invention is safer than an instantaneous and large correction force applied only at the time of surgery. Additionally, the continuous and controllable correction force is capable of gradually and fully correcting the spinal deformities without any post-operative manipulation of the correction device or re-operation.

With limited nutrients within the avascular disc, the water-retaining proteoglycans begin to diminish, resulting in dehydration, flattening and/or bulging of the disc. The flattened disc causes segmental instability, eroding the facet joints and causing pain.

In this invention, a disc inserting device contains a horizontally oriented protrusion with superior and inferior plateaus for inserting into the degenerated disc to maintain or restore disc height. The horizontally oriented protrusion is adjoined to a vertically oriented concave bracket with screw holes for fastening the concave bracket to the vertebral bodies sandwiching the degenerated disc. Thereby, the disc height is restored and fortified to reduce segmental instability and erosion of facet joints for pain relief. Furthermore, by altering the slopes of the plateaus, thickness and depth of the protrusion, spinal stenosis, scoliosis, kyphosis, lordosis or spondylolisthesis can be corrected with the disc inserting device.

The invention relates to a method for making a thoracolumbar vertebra deformity posterior individualized osteotomy navigation template.
