Sacrum Coccyx AP
4
Feb

Overview

The AP sacrum and coccyx radiograph evaluates the lower spine and pelvic ring for fractures and degenerative change. The patient is positioned supine with the detector centered to the sacrum. This view is used for trauma and chronic tailbone pain assessment.

Technique

Center the detector to include the sacrum and coccyx and use appropriate tube angulation if needed to project the sacrum free of pelvic superimposition. Ensure patient comfort and immobilize to reduce motion. Collimate tightly to reduce dose.

Clinical Indications

AP sacrum and coccyx are indicated for trauma tailbone pain and suspected fracture or infection. They help detect sacral insufficiency fractures and coccygeal dislocation. CT or MRI may be required for detailed evaluation.

Image Assessment

Assess sacral alar integrity coccygeal alignment and look for cortical disruption. Evaluate adjacent pelvic structures for associated injury. Report findings and recommend advanced imaging when clinical concern persists.

Sacrum Coccyx Lateral

Feb

Overview

The lateral sacrum and coccyx radiograph profiles the lower spine to assess alignment and fractures. The patient lies in true lateral with the detector centered to the sacrum. This view is useful for evaluating coccygeal angulation and sacral fractures.

Technique

Position the patient in true lateral and center the detector to include the sacrum and coccyx. Use appropriate exposure and immobilize the patient to minimize motion. Include adjacent pelvic structures when indicated.

Clinical Indications

Lateral sacrum and coccyx are indicated for trauma tailbone pain and suspected fracture or dislocation. They complement AP views for comprehensive assessment. CT or MRI may be required for detailed evaluation of complex injuries.

Image Assessment

Evaluate coccygeal angulation sacral body integrity and posterior element alignment. Inspect for cortical disruption and callus formation on follow up. Report findings relevant to pain management and surgical planning.

Pelvis Outlet View

Feb

Overview

The outlet view projects the sacrum and pubic rami to evaluate vertical displacement of the pelvic ring. The beam is angled cephalad to visualize the sacral foramina and pubic symphysis. This projection is useful in trauma to assess vertical shear injuries.

Technique

Angle the tube cephalad typically 40 degrees and center to the pubic symphysis. Keep the patient supine and immobilized to avoid motion. Use appropriate exposure to penetrate pelvic structures.

Clinical Indications

Outlet views are indicated for suspected vertical pelvic displacement and sacral fractures. They complement inlet and AP views for comprehensive pelvic trauma evaluation. CT provides detailed assessment for surgical planning.

Image Assessment

Evaluate sacral alignment pubic symphysis height and vertical displacement of hemipelvis. Inspect for sacral fractures and sacroiliac widening. Document measurements and recommend advanced imaging when indicated.
