Final answer:
The patient likely has an inversion ankle sprain, which is a common injury to the ankle. Treatment includes resting the foot, applying ice and compression, elevating the foot, and possibly using a brace or cast. Severe cases may require surgery.
Step-by-step explanation:
The patient has likely suffered an inversion ankle sprain, which is the most common injury to the ankle. This occurs when the foot is suddenly twisted inward, causing damage to the ligaments on the lateral side of the ankle. The anterior talofibular ligament and calcaneofibular ligament are commonly affected in this type of injury. In severe cases, the forceful movement of the talus can also result in a fracture of the distal fibula.
The management for an ankle sprain typically involves the RICE technique: Rest, Ice, Compression, and Elevation. This helps to reduce pain, swelling, and promote healing. In more severe cases where there is ligament tear or bone fracture, surgery may be necessary. Reducing joint mobility with a brace or cast may also be required for a period of time.
