Second metatarsal bone elongation, also known as Morton's toe (or Morton's foot) is a normal variation of the second metatarsal present in about 25% of the total population. Although normal, Morton's toe causes extra- inversion of the foot and thereby puts more stress on the lateral part of the meniscus of the knee, promotes lordosis of the ...
The base or posterior extremity is wedge-shaped, articulating proximally with the tarsal bones, and by its sides with the contiguous metatarsal bones: its dorsal and plantar surfaces are rough for the attachment of ligaments. The head or distal extremity presents a convex articular surface, oblong from above downward, and extending farther ...
The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the torso. [3] A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or toe. The proximal phalanges are those that are closest to the hand or foot.
There are three proximal tarsals, the tibiale, intermedium, and fibulare, named for their points of articulation with the bones of the lower limb. These are followed by a second row of four bones, referred to as the centralia (singular: centrale), and then a row of five distal tarsals, each articulating with a single metatarsal. In the great ...
The head (caput) or digital extremity presents an oblong surface markedly convex from before backward, less so transversely, and flattened from side to side; it articulates with the proximal phalanx. It is broader, and extends farther upward, on the volar than on the dorsal aspect, and is longer in the antero-posterior than in the transverse ...
The interphalangeal joints of the foot are the joints between the phalanx bones of the toes in the feet. Since the great toe only has two phalanx bones ( proximal and distal phalanges), it only has one interphalangeal joint, which is often abbreviated as the " IP joint ".
The pastern consists of two bones, the uppermost called the "large pastern bone" or proximal phalanx, which begins just under the fetlock joint, and the lower called the "small pastern bone" or middle phalanx, located between the large pastern bone and the coffin bone, outwardly located at approximately the coronary band.
The base or posterior extremity is wedge-shaped. [1] The base presents an oblique quadrilateral surface for articulation with the cuboid ; a smooth facet on the medial side, divided by a ridge into an anterior portion for articulation with the third metatarsal , and a posterior portion for articulation with the third cuneiform ; on the lateral ...
