Which device should be used to dorsiflex a patient's toes when positioning for a tangential projection of the sesamoids?

Using tape to dorsiflex a patient's toes is an effective method when positioning for a tangential projection of the sesamoids. This technique provides the necessary stability and tension to ensure that the toes are held in the correct position during the imaging process.

Dorsiflexion is essential in this context because it helps to visualize the sesamoids clearly by separating them from the metatarsal bones and other soft tissue structures. Tape allows for precise control of the toe position and can be adjusted easily to achieve the desired degree of dorsiflexion without causing discomfort to the patient or requiring excessive force.

In contrast, weights, sandbags, or elastic bandages may not provide the same level of specificity or control needed for this particular projection. Weights could add unnecessary pressure or pull in a way that affects the positioning negatively. Sandbags are generally used for immobilization rather than precise positioning of the toes. Elastic bandages might not provide the sufficient rigidity or anchoring needed for maintaining the toes in dorsiflexion consistently during the imaging process.

Therefore, using tape effectively meets the requirements for positioning in this imaging scenario, ensuring clear visualization of the sesamoids while maintaining patient comfort and safety.
