The invention relates to an intervertebral disc prosthesis for the total replacement of a natural intervertebral disc within the lumbar and cervical spine, comprising articulating sliding partners, where the upper sliding partner has means for a firm assembly to an upper vertebral body and the lower sliding partner has means for a firm assembly to a lower vertebral body and at least one sliding surface that is between two sliding partners. According to the invention, functional two- and three part designs are planned and both prostheses have in common, that only a dorsoventral- and rotation movement is possible as a result of laterolaterally aimed, transversally arched, ventrally curved cylindrical convexity(ies) and corresponding concavity(ies), however without an inclination of the sliding partners in a lateral direction. In a further design, the cylindrical articulation surfaces are un-curved, enabling a motion of the sliding partners in only a ventrodorsal direction. According to the invention, the intervertebral disc prostheses are suited for an implantation from lateral and ventrolateral, particularly in revision surgeries.

The invention relates to an intervertebral disc prosthesis for the total replacement of the intervertebral disc within the lumbar and cervical spine. For a two part as well as for a three part intervertebral disc prosthesis, according to the invention, in accordance to the design of the edges of the sliding partners, there are aspects for at least one of the sliding partners, in which there is an wavelike design of the edge, as the respectively differently high edge regions preferably fluently merge. A significant advantage of the two intervertebral disc prostheses, according to the invention, compared to the present state of the art of already known prostheses, is that as a result of a central transfer of load across a large surface area due to the spherical sliding surfaces, the maximally possible inclination of the sliding partners towards each other in a dorsoventral and laterolateral direction and / or the extent of rotation can, according to the invention, be defined through the wavelike design of the edge region.

An intervertebral prosthesis system, in particular for the cervical spine, includes at least two types of prothesis.

The present invention is directed towards a travel pillow for sleeping in a vertical or near-vertical reclined position. When sleeping in these positions, gravity tends to pull the head forward of the shoulders causing it to droop. The current state of the art travel pillow does not provide a support means to counter this forward drooping tendency. Moreover, its rear support displaces the cervical spine forward, further increasing the tendency for the head to slump forward. The present invention holds a resting head in an upright and stable position to prevent forward head drooping and does so without forwardly displacing the cervical spine. The five novel elements of the present invention are integrally configured to maintain a healthy alignment between the occipital bone of the head, the cervical spine of the neck, and the thoracic spine of the upper back.

The three-dimensional space cervical vertebrae rehabilitation instrument of the invention realizes the function of rotation at an optional angle in the three-dimensional space, restores physiologic front bends of cervical vertebrae, and exercises the functions of cervical vertebrae while carrying out traction, so as to effectively prevent deterioration of the physiologic curvature of the cervical vertebrae. The three-dimensional space cervical vertebrae rehabilitation instrument has a novel structure, is convenient in operation, can exercise the functions of cervical vertebrae while carrying out traction, and can restore the physiologic front bends of cervical vertebrae and reconstruct muscle force balance of muscles around the cervical vertebrae.

A cervical traction method and apparatus for treating irregularities in the lateral curvature of the cervical region of the spine involves the application of traction load to induce an axially elongated or extension posture in the cervical region of the patient's spine. The patient is placed in a supine or seated position, and a traction halter is fitted about the head of the patient, with a traction sling also being optionally positioned about the cervical region of the patient. A traction load, which may have an intermittently varying magnitude, is exerted on one or more of the sling or halter to induce an axially elongated and / or extension posture in the cervical region. The axially elongated posture at least partially diminishes the lateral curvature of the cervical region of the spine in the patient, and the extension posture at least partially restores the lateral curvature to the cervical region of the spine in the patient, thereby reducing symptoms such as neck pain, upper back pain, headaches, and other symptoms of mechanical origin that result from irregular lateral curvature of the spine.
