26
Q

Scheumanns diagnosis

A

X ray
3 adj vertebrae showing minimum 5 degrees wedging and kyphosis angle >45

27

Chest pain
PT t/x

A

40-60
Posterior or posterolateral
Better because IV foramen bigger

Diff diagnosis costovertebral jt dysfunction

A

Cardiac
Pneumonia
Pleuritis
Rib fracture

1st rib dysfunction
Due to
Need to rule out
How to confirm
Neuro sx

A

Trauma
Presence of cervical rib
X ray
None

35
Q

How to confirm presence of cervical rib

A

If 1st rib higher up to 1cm = joint dysfunction

1st rib higher up to 2+cm = cervical rib
