Description
Test Criteria
This view is used most commonly to assess for a pars interarticularis defect, although this has largely been superseded by CT and MRI. Additionally, it is a frequently used view for needle placement in fluoroscopic guided procedures 2, such as
- two radiographs performed with patient at RPO 35-45° and LPO 35-45°
- ensure arms are removed from the region of interest
- using a 45° radiolucent sponge in the supine position will assist the patient in maintaining the correct position, whilst flexing the knees will also provide stability.
