Question

Stress radiographs usually are requested when a patient has suffered from the following ankle injuries___________

Answer 1

Stress radiographs are typically used to assess severe ankle injuries such as inversion or eversion sprains, which may result in ligament tears or fractures.

Step-by-step explanation:

Stress radiographs are often requested when a patient has suffered from severe ankle injuries, particularly when damage to specific ankle structures is suspected. The most common injuries necessitating stress radiographs include severe inversion injuries such as inversion ankle sprains, which can damage the lateral ligaments and potentially fracture the distal fibula. More specifically, the anterior talofibular ligament is the most commonly injured. Eversion sprains, which are less common, involve the deltoid ligament and can lead to a Pott's fracture and dislocation of the joint. In both cases, stress radiographs help to evaluate the extent of the injury, including any potential tears in the ligaments or fractures in the bones.

For inversion sprains, the sequence of injury typically involves the anterior talofibular ligament first, followed by the calcaneofibular ligament, and finally, the posterior talofibular ligament. In the case of forceful eversion, the strong deltoid ligament may shear off the medial malleolus and result in the lateral movement of the talus, causing a fracture to the distal fibula and possibly damaging the posterior margin of the tibia as well. Treatment for most ankle sprains can include the RICE technique, but more severe injuries might require immobilization or surgery.

Answer 2

Stress radiographs are usually requested when a patient has suffered from severe ankle injuries, such as ligament tears or bone fractures. These injuries can occur from ankle sprains and stress fractures from repetitive striking of the foot on the ground. Stress radiographs help evaluate the stability and alignment of the ankle joint.

Step-by-step explanation:

Stress radiographs are usually requested when a patient has suffered from severe ankle injuries, such as ligament tears or bone fractures. These injuries can occur from ankle sprains, both inversion sprains that damage the ligaments on the lateral side of the ankle and eversion sprains that involve stretching of the deltoid ligament on the medial side of the ankle. Other injuries that may require stress radiographs include Pott's fracture and dislocation of the ankle joint, and stress fractures from repetitive striking of the foot on the ground.

Stress radiographs are helpful in evaluating the stability and alignment of the ankle joint, which cannot always be determined from regular X-rays. They involve taking X-rays while applying stress or pressure to the ankle, which allows for a better assessment of ligament laxity or abnormal movement.

In summary, stress radiographs are requested for severe ankle injuries, including ligament tears, bone fractures, Pott's fracture, dislocation of the ankle joint, and stress fractures. They help evaluate the stability and alignment of the ankle joint.
