Anatomical Effects Of Rotation On Atlantoaxial Joint And Lumbar Spine Mr. N K Rath 1*, Dr X Yang 2, Dr K Lyons 1, Prof L Nokes 2, Mr M J H McCarthy 1 1. University Hospital of Wales Cardiff 2. Cardiff School of Engineering
Back pain One third of UK population 20% will seek medical attention Financial burden of 1000 million pounds 90 % of these settle with physiotherapy
Background Paucity of literature on effect of rotation on neural compression Most of MRI studies have focused on range of motion Spine coupled motion Disc failure and prolapse – bending and rotation
Objective To collect normal variant data Understand the effect of range of motion on lumbar disc deformation and neural foramen Understand the normal subluxation at atlantoaxial joint
Method Phase 1 pilot study Ten healthy male volunteers Signed consent MRI Cervical and lumbar spine at different rotational position Radiological evaluation of the MRI scan by senior radiologist
Inclusion Criteria Fit and well male volunteers Age <20-30 BMI Height between 5’6” and 6’ No previous back problems or interventions No degenerative discs or other abnormalities Normal endplates, no Modic changes Complete standard neck and low back pain questionnaire to prove normal PROMs (patient reported outcome measures / scores)
MRI Perform Standard Supine MRI cervical and lumbar Spine T1, T2 Sagittal and T2 Axial cuts 3D acquisition using body coil. Perform Lower Limb Rotated MRI to Right with Shoulders Supine T1 T2 Sagittal and T2 Axial cuts 3D acquisition using body coil and beanbag to minimize motion artifact. Perform T1, T2 sagittal and T2 axial cut 3D acquisition for rotation at atlantoaxial joint at neutral, 45 degree and maximum range.
Project Update Ethical approval received from Cardiff school of engineering. Project passed by ethical approval team of Nuffeild health private hospitals Price negotiated with Nuffeild health private hospitals Flyers for volunteer recruitment via Cardiff University under way Expected date of start of scans 30 th may
