This projection will demonstrate an ___ position of the femoral ___, ___, and ___ areas.
The frog leg position is contraindicated for the patient suspected of having a ___ or other pathological disease. ___ lateral hip projections would be taken in this case.
Bilateral Frogleg Lateral Position - Modified Cleaves Method
The patient is supine with knees flexed enough to place the plantar surface of the feet on the table top.
Direct CR to midsaggital plane about 1 inch superior to the pubic symphysis.
Abduct the thighs as much as possible and have the patient turn the feet inward to brace the soles against each other for support. Be sure to abduct the thighs to the same degree to prevent rotation of the pelvis.
This projection will demonstrate an oblique position of the femoral heads, necks, and trochanteric areas.
The frog leg position is contraindicated for the patient suspected of having a fracture or other pathological disease. Surgical lateral hip projections would be taken in this case.
