Digital Motion X-ray records a sequence of X-ray images during guided movement, adding motion information to a clinical evaluation
What a motion study can add
What the study shows
DMX uses fluoroscopy to show changes in bone position as a joint moves. A recorded sequence can be reviewed frame by frame to evaluate visible alignment and motion.
By showing movement in real time, DMX imaging can reveal problems that static imging modalities like MRIs, CTs, and X-rays cannot capture.
CCI, CI, EDS, and hypermobility
Craniocervical Instability (CCI) is a condition where the ligaments (alar ligaments, transverse ligament, etc.) that hold the occiput, C1 vertebrae, and C2 vertebrae are damaged Cervical instability (CI) is a condition where the ligaments that hold ther lower cervical vertebrae together are damaged. Both CCI and complex CI can cause an array of pain, dizziness, or autonomic symptoms and can be difficult to detect via static imaging. Elhers-danlos syndrome (EDS) and patients with severe hypermobility have connective tissues that is too loose to support their skeletal structure. These loose connective tissues may affect specific areas that may be missed with static imaging. Digital Motion X-ray (DMX) provides a specialized diagnostic solution by capturing real-time joint movement to view the exact location and severity of the ligament damage.
Sample DMX Studies
Cervical Flexion DMX
The C4 vertebrae slides anterior to C5 when flexing head indicating Anterior Longitudinal Ligament instability. The C4/C5 facet joint gaps with flexion indicating capsular ligament damage. Cervical flexion can also visualize C1 sliding anterior to the dens of C2, widening the atlanto-dental interspace indicating torn transverse ligament and confirming CCI.
Cervical Oblique Flexion/Extension DMX
This view allows us to evaluate the foramen for stenosis or impingment throughout full range of motion. Also evaluates facet capsular ligments for intability.
APOM Lateral Bending DMX
The lateral mass of C1 slides over the vetebral body of C2. The paraodontoid spaces increase/decrease as the patient laterally bends left and right. This indicates left and right alar ligament instability.
Left Wrist Deviation DMX
DMX imaging can be done on extermities to visualize unstable ligaments and their movement patterns.
Cervical Spine with Implant Flexion/Extension DMX
Visualizes a disc implant and spinal biomechanics during flexion and extension.
These sample studies demonstrate the image clarity that DMX of San Diego will provide
