Upper cervical spine is thought to contribute approximately 60 of rotation, 40 of Flexion. Approximation of the flexor surfaces whereby the angle of the joint is reduced. Elbow flexion brings volar surface of forearm and arm flexion of knee, flexor surface or posterior surfaces of leg and thigh come close. " approximation of the extensor surfaces whereby the angle of the joint is increased and flexor surfaces are moved from proximity. It is opposite to flexion. " and 45 of overall neck motion. The normal axial plane C12 rotational excursion amounts to 80 to 88 degrees from left to right.ligamentous check rein and muscular control. Together these contribute to the movements in the neck substantially. This enables us for a rapid response and large-scale head excursion.
These vertebra are shaped different from rest of cervical spine to protect these vital structures and allow for mobility of the head. An injury to osseoligamentous components in this region may therefore compromise structural integrity dames of the entire craniocervical junction and therefore needs to be addressed separately from rest of cervical spine. Because of complex anatomy and a major role played by ligaments in stability, this region is quite vulnerable to injury in high energy trauma. This unique composition also makes the assessment difficult and aid of imaging studies becomes very important. The assessment should be performed according to standard guidelines and should include cranial nerve examination. Prior to advent of trauma management systems, these injuries were almost always fatal but the survival has been improving with better management. In conscious, oriented patients the symptoms of neck pain, headache, and tenderness in the area might suggest the injury to this area. Neurologic deficits range from complete high quadriplegia to incomplete injuries, such as cruciate paralysis or disorders affecting brainstem function. Unconscious patients pose an increased diagnostic challenges and need to be scrutinized for possible spinal column and cord injury. The imaging studies play a greater role in these cases.
Cervical Spine Bracing Options: Halo
Cervical Spine Injury bone and Spine. You are here: Home spine cervical Spine / Cervical Spine Injury,. Dr Arun Pal Singh, upper Cervical Spine Injury, the upper cervical spine injury that occurs in two unique vertebrae, the atlas (C1) and the axis C2) and adjoining structures. The skull base lichaam with its bony and ligamentous elements surrounding the foramen magnum plays an integral part in maintenance of the normal functional alignment of these two cervical vertebrae. Technically however, skull base is not a part of upper cervical spine. Upper cervical spine injury also includes all osseous and ligamentous structures between the skull base and the cranial side of the c-3 vertebra. The integrity of the craniocervical junction is of crucial for survival and function. It is here that transition from brainstem to spinal cord occurs.

The halo is a device for treatment of unstable cervical and upper thoracic fractures an d dislocations from C1. The halo provides greater motion restriction than any other cervical orthosis. The halo ring is made of graphite or metal, with pin fixation on the frontal and parietal-occipital areas of the skull. Designed to be an external fixation device for the cervical and upper thoracic spine, the halo brace serves as a rigid frame that. Halo, patient Information Manual. The halo has provided more effective and reliable immobilization than other orthoses. It is an acceptable alternative to cervical fusion for the achievement of stability in a wide variety of cervical spine fractures and dislocations avoiding both the short-term and perhaps long-term complications of spinal fusion. Halo vest is used in management of cervical spine diseases where spine needs ex ternal stabilization.
In case of hands infection of a pin tract, the pin is removed and another pin is placed in a new site. Secondary loss of reduction may occur due to snaking mechanism of the cervical spine between the supine.
A halo, also known as a halo ring or halo crown, is a piece of equipment that encircles and is fixed to the head of a patient. This device is crucial for the management of a variety of conditions that destabilize the cervical spine. Halo, brace care a, halo brace is used chinese most often after a neck injury. This brace holds your neck ( cervical portion of your spine) in place. A halo is a medical device used to stabilize the cervical spine after traumatic injuries to the neck, or after spine surgery. The apparatus consists of a halo vest, stabilization bars, and a metal ring encircling the patient s head and fixated to the skull with multiple pins.

The duration of application varies depending upon the nature of injury and purpose for which halo vest is applied. The assembly is well tolerated by most of the patients. Patients are regularly followed up with series of radiographs that were performed initially to ensure adequate positioning and stabilization of the cervical spine. . In addition, the physician will do a complete neurological assessment of the patient and tighten all of the hardware on the halo vest. A neural mask examination is also done at the follow up visits. Complications of Halo vest, pin loosening is by far the most common of the potential complications. This happens for around 60 of patients. This can be avoided by early detection of loosening at weekly follow-up visits. Infection at the pin sites is another complication that occurs 10-20 of patients.

Halo vest can be used in following situations groningen in cervical spine injuries or other pathologies that affect stability of spine. To stabilize spine for treatment with non operative means. In adjunct with a surgical procedure to provide additional stability. In follow up to patients who were treated initially with skeletal traction. How Is Halo vest Applied, four pins that are equally space are placed in the skull two over the ridge of the orbit and one each just behind the ear. The halo ring is fixed to these pins. Following this vest is applied to the torso and connected with adjustable metal rods to halo ring. After the assembly is in place radiographs are taken to check position of cervical spine ad if any change need to be made. A neurological examination is made after application of halo vest.
Before this only method cream to effectively restrict cervical spine mobility was traction in Supine nbsp;Lying down (recumbent) position with the face directed upwards. By attaching the halo to a device worn around the patients torso, complications of recumbency like bed sores and chest infection can be avoided. A ring is fixed to patients head by means of screws and the ring is attached to rigid, lightweight vest that fits snugly around the patients chest. This way the apparatus can provides spinal stability while allowing the mobility. Halo vest offers following advantages over the traditional traction system. Precise positional control, efficient external stabilization of the cervical spine. Low complication rate, minimal patient discomfort, early patient mobilization. Where can Halo vest be used?

By, dr Arun Pal Singh, halo vest consists of a halo and vest. Halois a ring that is encircles the head and is fixed to it by means of pins that are inserted in the head. It is also known as halo ring or halo crown. Halo vest is used in management of cervical spine diseases where spine needs external clinic stabilization. Halo ring part of halo vest can be used to put traction on the cervical spine or to provide external support and immobilization. In the latter case the ring is attached to a brace that encircles patients torso and the whole assembly is termed as halo vest. Image Credit: g, the concept of was first brought out in late 1950s.
