Final answer:
The pain described by the 46-year-old female following a 'pop' sound during soccer is likely tied to an inversion ankle sprain affecting the anterior talofibular ligament and possibly the calcaneofibular ligament. A medical evaluation is essential to determine the severity of the sprain or to rule out fractures.
Step-by-step explanation:
In the case of the 46-year-old female experiencing pain in her ankles, particularly her right ankle following a 'pop' sound while playing soccer, several structures of the foot might be involved. The joints of the ankle, specifically, are likely affected. An inversion ankle sprain is a common injury and is characterized by the stretching or tearing of the supporting ligaments.
The anterior talofibular ligament is the most frequently injured, followed by the calcaneofibular ligament. The 'pop' might signify a more severe event, possibly including the rupture of ligaments or even a fracture of the distal fibula. Given the ability to bear weight, a complete rupture or severe fracture is less likely, but a medical evaluation is warranted for accurate diagnosis and treatment.
