| **F2Ps** = angle between the projections of the line segments FMH-PM and FMB-FMH into the sagittal plane of the metatarsus, positive angle with the former rotating upward, i.e. dorsiflexion of the first metatarso-phalangeal joint. | **F2Ps** = angle between the projections of the line segments FMH-PM and FMB-FMH into the sagittal plane of the metatarsus, positive angle with the former rotating upward, i.e. dorsiflexion of the first metatarso-phalangeal joint. | ||
| **MLA** = angle between the projections of the line segments CA-ST and ST-FMH into the sagittal plane of the foot, positive angle with clockwise rotation of the former toward the latter, i.e. navicular drop being positive. This would replicate somehow what is known in radiography as the Moreau and Costa Bertani angle. To make sure all three markers (CA, ST and FMH)are not colinear, it is recommended to use the CAB marker instead of the CA since the CAB is lower than the CA marker, ensuring the angle is more acute. | **MLA** = angle between the projections of the line segments CA-ST and ST-FMH into the sagittal plane of the foot, positive angle with clockwise rotation of the former toward the latter, i.e. navicular drop being positive.
