CERVICAL ORTHOSES

Orthoses for the cervical spine are designed to immobilize cervical spinal segments that are unstable, deformed or have recently undergone spinal surgery. The goal is to provide the best biomechanical environment for these disorders or surgeries to heal. These devices range from mildly immobilizing to maximal immobilization and should be choosen specifically for:
1. The level of the cervical spine that is affected. It is best to think of these levels as three distinctly different groups, each with different planes of mobility and distinctly different immobilization needs. a) The upper cervical spine (Occiput-C2) is unique as it is the one area of the spine that is under the least amount of load as it is the highest part of the spine, yet this is an area of great vulnerability to to injury as C1 has a small ring of bone that circles a “post” known as the odontoid or dens of C2. This ring and post gives us our rotational ability of the neck and is frequently refered to as the “no-no” joint as it allows us to move our head in the transverse direction (z-axis) to make the “no-no” gesture. If this post (odontoid) is fractured to a point of instability, this could be life threatening or cause quadraplegia. The best non-operative method to immobilize this is to use a cervical halo system (pictured above) as this is the only device that will immobilize the z-axis motion (no-no). Nowadays, there are better surgical alternatives for this type of injury, but not everyone is a candidate for this procedure. dependending on the severity of the injury, a Halo must be worn for at least six weeks, and sometimes up to a year.
One level above the C1-C2 joint is the occiput (base of the skull) and C1 joint complex. This complex contains joints called facets that allow the “yes-yes” motion (x-axis-sagittal plane) and, depending on the severity of the injury, may be immobilized in an extended care cervical collar, or a cervical thoracic orthosis (pictured below)

BIONICS

Bionics (also known as biomimetics, biognosis, biomimicry, or bionical creativity engineering) is the application of methods and systems found in nature to the study and design of engineering systems and modern technology.Some dictionaries, however, explain the word as being formed from “biology” + “electronics”.

The transfer of technology between lifeforms and synthetic constructs is desirable because evolutionary pressure typically forces natural systems to become highly optimized and efficient. A classical example is the development of dirt- and water-repellent paint (coating) from the observation that the surface of the lotus flower plant is practically unsticky for anything (the lotus effect). Examples of bionics in engineering include the hulls of boats imitating the thick skin of dolphins; sonar, radar, and medical ultrasound imaging imitating the echolocation of bats.
