An orthopedic walking boot includes a housing configured to encompass at least a user's foot, a mechanically adjustable ramp insert including a ramp surface and disposed in the housing, an adjusting mechanism configured to adjust an elevation angle of the ramp surface, and a mechanically adjustable lift configured to cause the mechanically adjustable ramp insert to descend within the housing as the ramp surface is elevated such that vertical displacement of the user's foot caused by elevation of the ramp surface is substantially attenuated. Related methods are also provided.

A buoyancy-based cervical traction system has a floatation and a head rest supported by the flotation system. The head rest is adapted to support a person's head above the neck and apply traction to the neck when the person is in a body of liquid. The system has a position adjustment system adapted to allow selective adjustment of the position at which the person's head rest will be relative to an upper surface of the liquid when the person and the cervical traction system are in the liquid, the person's head is supported by the head rest, and the cervical traction system and person are floating in the liquid at equilibrium.

The present subject matter relates to orthotic devices, systems, and methods configured to support a lumbar spine. In some embodiments, a lumbar spinal orthosis system includes a torso belt configured to be secured about a torso of a user, a pelvic belt configured to be secured about a pelvis of the user, and a distractive force mechanism connected between the torso belt and the pelvic belt. The distractive force mechanism is configured to generate a force between the torso belt and the pelvic belt acting bi-directionally across a lumbar spine of the user to substantially offload bodyweight of the user passing through the lumbar spine.

A wound treatment appliance is provided for treating all or a portion of a wound. In some embodiments, the appliance comprises a cover or a flexible overlay that covers all or a portion of the wound for purposes of applying a reduced pressure to the covered portion of the wound. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the site of the wound in the volume under the cover or in the area under the flexible overlay. Methods are provided for using various embodiments of the invention.

A sling of a portable traction device cradles a user's head primarily at the back and lower part of the skull. The sling is attached to at least one shock cord. The at least one shock cords is also anchored to a structure, such as a closed door at the hinged side of the door, between the door and door frame, using an anchor, at a height, to generate a tension vector at an acute angle relative to the floor. The tension applies cervical traction.

A portable traction device can include a sling that is sized to cradle a user's head primarily at the back and lower part of the skull. The sling can be associated with flexible elastic tethers that are, in turn, associated with an anchor that is positioned a height above the floor when the portable traction device is in use. A tensile force vector between the anchor and the sling allows for cervical traction. The sling can additionally be associated with speakers and/or resonant actuators and can be simplified to increase portability and ease of use.
