- Ankle injured; patient cannot bear weight. Which set is appropriate?
Answer: AP, mortise, lateral views
For an injured ankle with no weight-bearing ability, choose the non-weight-bearing three-view series: AP, mortise, and lateral. This covers bony injury and joint alignment without stressing the limb. Weight-bearing views are tempting for checking instability, but you can't use them when the patient can't bear weight, and a lateral/oblique pair alone is incomplete.
- A patient with a suspected scaphoid fracture has their wrist immobilized in a fiberglass cast that extends from the mid-forearm to the metacarpal heads. The cast cannot be removed, and the physician specifically requests visualization of the scaphoid waist. Which projection modification would provide the BEST visualization of the scaphoid through the cast material?
Answer: Modified Stecher projection (PA with ulnar deviation) and increase mAs by 30-50% to penetrate the fiberglass cast material
The modified Stecher projection (PA with ulnar deviation) elongates and profiles the scaphoid, making it the optimal projection for scaphoid waist visualization. Fiberglass cast material requires approximately 30-50% increase in mAs (not kVp) to maintain image quality while penetrating the cast. Option A (proximal angulation) is incorrect angulation for scaphoid visualization. Option B (lateral with posterior angulation) would not adequately demonstrate the scaphoid waist due to overlap with other carpal bones. Option C (radial deviation) would foreshorten the scaphoid rather than elongate it, and kVp increase alone is insufficient for cast penetration.
- A 16-year-old athlete presents with acute ankle injury during a basketball game. The ankle is severely swollen, and the patient cannot bear weight or move the foot. A fracture of the lateral malleolus is suspected. The patient is anxious about the injury affecting their sports career. Which approach would be MOST appropriate for the initial radiographic examination?
Answer: Obtain AP and lateral ankle projections with the patient supine, using horizontal beam technique for the lateral to avoid moving the injured ankle
When encountering acute trauma cases, especially in young athletes, your radiographic approach must balance diagnostic needs with patient safety and comfort. The key principle is minimizing patient movement while obtaining essential diagnostic information.
Option B is correct because it provides the two most critical projections (AP and lateral) while keeping the patient in a stable supine position. Using a horizontal beam for the lateral projection eliminates the need to manipulate or move the injured ankle, which could worsen the injury or cause unnecessary pain. This approach follows trauma radiography protocols that prioritize patient safety while still obtaining adequate diagnostic information for fracture assessment.
Option A is problematic because attempting a complete three-projection series would require moving the acutely injured ankle for proper positioning, potentially causing additional trauma or displacement of fracture fragments. The oblique projection, while useful, isn't essential for initial fracture assessment.
Option C takes an incomplete approach that may require the patient to return for additional imaging, increasing radiation exposure and delaying treatment. Starting with inadequate projections isn't efficient in trauma situations.
Option D is completely inappropriate for acute trauma. Stress projections involve deliberate manipulation of the joint and should never be performed when fracture is suspected, as this could cause severe damage to bone and surrounding tissues.
Remember: In acute trauma radiography, always prioritize patient safety and pain management. The horizontal beam technique is your best friend when patients cannot be moved safely. Two well-positioned projections are better than three poorly positioned ones that compromise patient care.

- Wheelchair patient can't rotate arm for lateral wrist. Best adaptation?
Answer: Rotate the patient's body
For a true lateral wrist, the radius and ulna must be superimposed. If the patient cannot rotate the arm, rotate the whole body in the chair to bring the positioned arm and wrist into a true lateral. Rotating the patient's arm is tempting but is exactly what the patient can't do, and forcing it risks pain or injury. Angling the beam or doing an oblique won't create a true lateral.

- A motorcycle accident victim presents with multiple trauma including a suspected femoral neck fracture. The patient is on a backboard with cervical spine immobilization and cannot be moved for standard hip projections. Vitals are stable, but the patient is conscious and reports severe hip pain. Which projection sequence would provide adequate diagnostic information while maintaining spinal precautions?
Answer: Cross-table lateral hip followed by AP pelvis with the patient remaining supine on the backboard throughout both projections
For trauma patients with spinal immobilization, the cross-table lateral hip and AP pelvis can both be performed with the patient remaining supine on the backboard. The cross-table lateral provides visualization of the femoral neck relationship and potential displacement, while the AP pelvis gives overall pelvic anatomy assessment. Both projections maintain spinal precautions. Option B (frog-leg lateral) requires hip manipulation that could worsen a fracture and violate spinal precautions. Option C (Judet obliques) are for acetabular assessment, not femoral neck evaluation. Option D suggests moving the patient despite spinal precautions, which is contraindicated until spine injury is ruled out.

- An elderly patient with severe rheumatoid arthritis is unable to fully extend their fingers for a PA hand projection. The metacarpophalangeal joints are contracted in 45-degree flexion, and the patient experiences significant pain with any attempt at extension. What is the BEST approach to demonstrate potential fractures in the phalanges?
Answer: Take individual finger projections with the central ray perpendicular to each digit while maintaining the patient's comfortable hand position
For patients with severe arthritis and fixed contractures, individual finger projections allow the central ray to be positioned perpendicular to each digit while respecting the patient's anatomical limitations. This technique provides optimal visualization of each phalangeal bone structure without causing pain or potential injury.
