Traditionally, the chiropractic profession has employed two different methods to describe spatial relationships (i.e., listings) of subluxated vertebrae for corrective orientation purposes. These methods (Palmer- Gonstead - Firth and Diversified), in addition to being somewhat limited in their scope of application, do result in some confusion. This paper, therefore, proposes a new method designating vertebral position and movement based on the "right-handed orthogonal coordinate system" of White, Panjabi and others.

There can be no lateral displacement of the atlas (massae laterales) in relation to the condyles, because this is impossible from an anatomical point of view, neither "angular" (atlas A rule) nor "non-angular" (atlas B rule) in the sense of the "hole-in-one (HIO)" diagnostic method evolved by the U.S. chiropractor Palmer. The course of the condyle baseline is not altered by a lateral displacement of the atlas in relation to the condyles, but by a tilting rotation of the condyles in respect of the atlas.

Brucellosis infection in humans is very rare in the United States. Occasional cases are identified primarily in individuals who have been exposed to an animal's raw dairy products. Presented is a rare case of human brucellosis involving the cervical spine. Of interest is how the case unfolds, reminding the practitioner of the need for thorough clinical practice. A review of clinical features and findings is offered.

The purpose of this paper is to review the current information on atlantoaxial instability in Down's syndrome. There are potentially fatal consequences to performing adjustive manipulation to the cervical spine of the Down's patient. Atlantoaxial subluxation can cause death. Up to 50% of those suffering from atlantoaxial instability have it due to anomalous axis formation and/or agenesis or laxity of the transverse ligament. Trauma or progressive anterior displacement of atlas may cause serious neurological complications.

OBJECTIVE: Little attention has been given to the craniovertebral articulations. Specifically, gross observations of variations of the superior articular facets on the atlas have not been described with respect to static and motion palpation findings. This study describes the anatomical variations of these facets and the clinical implications associated with asymmetrical structure.

OBJECTIVE: To compare two methods of obtaining the anteroposterior (AP) open mouth view. DESIGN: Radiological evaluation of the occiput-C1/C1-C2 structures, as visualized on radiographs obtained using two different radiographic position set-ups. SETTING: The Anglo-European College of Chiropractic Clinic. PATIENTS: A total of 60 patients. Each method used on 30 patients. CRITERIA ASSESSED: Visualization of: (a) occiput-C1 joints, (b) atlantoaxial joints, (c) lateral masses C1 and (d) odontoid process.

OBJECTIVE: To discuss the diagnosis, management and possible mechanism of atlantoaxial rotatory fixation. CLINICAL FEATURES: An 11-yr-old girl with significant head tilt of 7 months' duration sought chiropractic evaluation. Her history included indirect head and neck trauma from a motor vehicle accident and prior manipulative and therapeutic treatment. There was minimal muscular hypertonicity, except for the sternocleidomastoid muscle on the side opposite head tilt. The head seemed to be locked in a classic "cock robin" position.

OBJECTIVE: To discuss the management and resolution of suckling intolerance in a 6-month-old infant. CLINICAL FEATURES: A 6-month-old boy with a 4(1/2)-month history of aversion to suckling was evaluated in a chiropractic office. Static and motion palpation and observation detected an abnormal inward dishing at the occipitoparietal junction, as well as upper cervical (C1-C2) asymmetry and fixation. These indicated the presence of cranial and upper cervical subluxations.

OBJECTIVE: To determine whether lumen narrowing in vertebral arteries during atlanto-axial rotation is due to stretch or localized compression. DESIGN AND SETTING: Experiments with models were made in a private chiropractic clinic, whereas studies of cadaveric specimens were performed in an anatomy laboratory. Doppler ultrasound and magnetic resonance angiography (MRA) studies were carried out in the radiology department of a public hospital. PATIENTS: Eight patients had their vertebral arteries examined by use of a Doppler velocimeter and MRA.
