BOOTY’S FINAL EXAM MATERIAL NOTES Facet arthrosis Book : Facet arthrosis is infrequently observed in the thoracic spine, except in the lower thoracic segments. Facet arthrosis deals with apophyseal articulations . The most common locations for facet arthrosis ar in the L4 and L5 articulations. Arthrosis in these locations is characterized by loss of joint space, sclerosis, osteophytes, and subluxation, particularly anterolisthesis. The oblique film gives the best view. When facets become arthritic they make spurs and these spurs can encroach into the IVF. Causes pinching of the spinal nerve; this is a “pinched nerve.” You can get spurs from the Von Luschka joint as well which can protrude into the IVF. Von Luschka degeneration PAGE 965 The patient may have severe pain and can’t function, or could walk into your office with a totally different complain somewhere else. When you loose joint space; the vertebral body slides forward – called degenerative anterolysthesis/spondylolisthesis. There is no separation of the pars. There are 5 types of spondylolisthesis, this is the degenerative one. Book: Degenerative changes of the apophyseal joints allow for up to 10-30% anterolisthesis of the involved vertebral segment. Such changes are most common at the L4 level and are more common in females .40 years of age. In the cervical spine, it is most frequent at the C7 level. Anterolisthesis occurs as a combination of loss of joint space, loss of disc height, remodeling of the facet surfaces to a more sagittal orientation and broadeneing of the pedicle facet angle. It frequently is associated with lateral and central canal stenosis PAGE 975-976 o It goes forward because we have lost joint space due to spurs. Remember the white line on the film – it’s important – means degeneration. Pseudo fracture represents Luschka joint arthrosis.

Talked about osteophytes aka bone spur again and how they have a cartilaginous cap which helps them to grow. (Trisha told me to write this down…. .damn dictator!) o They look triangular and are obliquely orientated. They usually come off the endplates. Schmorl’s node – are found at the inferior end of the end plate ; not on all of the vertebrae like biconcave vertebrae. They are more widespread and scooped out at the top and bottom. o Flexion malposition – disk gets injured which allows for compression which will develop into disk degeneration or intervertebral osteochondrosis. Intervertebral osteochrondrosis aka discogenic spondylosis – showed us on film at multiple levels

From most anterior aspect of spinolaminar line to the most posterior aspect of vertebral body is called the neural canal.

o The minimum acceptable sagital canal length is 12 centimeters If its 12 its considered relative canal stenosis 8mm or less is absolute spinal or neural canal stenosis. These people will have laminectomies done unfortunately
