“Metatarsus Adductus (MTA)” refers to medial deviation of the forefoot relative to the midfoot and/or hindfoot in the transverse plane, characterized by adduction of one or more metatarsals toward the foot midline. MTA may be flexible or rigid, mild to severe, and may be assessed on anterior–posterior weight-bearing radiographs using angular or axis-based measures and/or categorical indicators (e.g., a plumbline status), and the like. … more “Metatarsus Adductus (MTA)” refers to medial deviation of the forefoot relative to the midfoot and/or hindfoot in the transverse plane, characterized by adduction of one or more metatarsals toward the foot midline.

"Registration key" refers to a structure, surface, feature, module, component, apparatus, and/or system that facilitates, enables, guides, promotes, precision in the alignment of two objects by way of registration. In one aspect a registration key can include a surface and one or more recesses and/or features of that surface that are configured to fit within corresponding recesses, projections, and/or other features of another structure such as another surface. In certain aspects, the features of the registration key may be configured to fit within, or in contact, or in close contact with those of the another structure. In one embodiment, when the two structures align the registration key has served its purpose. … more "Registration key" refers to a structure, surface, feature, module, component, apparatus, and/or system that facilitates, enables, guides, promotes, precision in the alignment of two objects by way of registration.
