The central poin of AP ankle joint:
- a- Lateral Malleous
- b- Medial Malleous
- c- Midway between the malleoli
- d- Center of the calcaneus
the answer is C.
The central point of the AP ankle joint is c) Midway between the malleoli. Here's why:
- Malleoli:
The malleoli are the two bony bumps at the ankle, with the lateral malleolus on the outer side and the medial malleolus on the inner side. Neither is the central point.
- Calcaneus:
The calcaneus is the heel bone, located below the ankle joint. It's not directly related to the central point of the joint itself.
- Midway between the malleoli:
This point lies directly in the center of the mortise joint, which is the main articulation of the ankle. The talus bone sits within the mortise, formed by the grooves of the tibia and fibula (leg bones). This central point is crucial for proper alignment and weight distribution in the ankle joint.
Therefore, considering the anatomical structure and function of the ankle joint, the midway point between the malleoli is the most accurate representation of its central point.
