Preface The staff in accident and emergency departments and doctors in fracture clinics alike may at times find themselves inadequately equipped to identify the exact type of a given fracture without access.

Either mechanism could be a primary or secondary through tractioning of the zygapophyseal joint capsule source of pain and muscle spasm Saboe ; Mercer As the patient commences turning to the right, the accessory glide having been applied and maintained, two important events occur.

For the purposes of this discussion a unilateral SNAG, performed ipsilateral to the side of pain and movement restriction for an adult patient with painfully restricted right rotation, will be used as an example Fig.

Human Structure Summer Manual Therapy 7 2Lysell E Motion in the cervical spine. If the cervical spine responds in a manner similar to the superoanteriorly directed glide during a cervical SNAG, cervicl similarly complex spinal motion pattern may occur, potentially increasing the cervical lordosis and therefore weightbearing through the posterior columns.

From This Paper Topics from this paper. Thirdly, it is unlikely that osseous pathology would undergo immediate and prolonged improvement following mobilization, thus implicating soft tissue structures such as meniscoid inclusions, the zygapophyseal joint capsule and intervertebral enags as the most likely articular sources for any manually reversible pain. Fortunately, most back and neck pain is temporary, resulting from short-term More information.

Pain Physician ; Although a cervical SNAG may clinically be able to resolve painfully restricted cervical spine movement, it is difficult to explain biomechanically why a technique which first distracts opens and then compresses closes the zygapophyseal joint ipsilateral to the side of pain, and perhaps slightly distracts the uncovertebral cleft, would be superior to a technique which distracts the articular surfaces with both accessory and physiological movement components.

The cardinal rule governing this procedure is that all movement, both accessory and physiological, must be painless Mulligan a, Penning L Physiology and biomechanics: After anterior discectomy in either the cervical or lumbar region there is a need to replace the removed disc with something and the choice lies between.

Journal of Manipulative and Physiological Therapeutics Although the biomechanicaal technique could theoretically resolve these problems it is difficult to explain biomechanically why a technique which first distracts and then compresses the ipsilateral zygapophyseal joint, and perhaps slightly distracts the ipsilateral aspect of the uncovertebral cleft, would be superior to a technique which distracts the articular surfaces with both accessory and physiological movement components.

Thus, a patient with painfully restricted right rotation would initially be treated with a unilateral SNAG on the ipsilateral right articular pillar Mulligan Fig.

However, several assumptions related to the clinical application of cervical SNAGs require stating beforehand. MD; Yurth, Elizabeth F. Hartman L Classification and application of osteopathic manipulative techniques.
