* The proximal phalanx tends to be triangular with the interdigital surface being flattened. The proximal end is concave with a sagittal groove so it can articulate with the metacarpal bone, the palmar aspect has facets for the sesamoid bones. The distal head has two convex areas seperated by a sagittal concavity.
* The proximal phalanx tends to be triangular with the interdigital surface being flattened. The proximal end is concave with a sagittal groove so it can articulate with the metacarpal bone, the palmar aspect has facets for the sesamoid bones. The distal head has two convex areas seperated by a sagittal concavity.
* The middle phalanx is three sided and 2/3rds the length of the proximal one. The proximal end is made up of two concavities and a sagittal ridge. The distal end resembles that of the proximal phalanx.

* The distal phalanx is pointed, the proximal end has two articular surfaces seperated by a ridge. The solar surface is flattened and has a flexor tubercle for the attachment of the deep digital flexor tendon. The axial surface faicng the other digit is also flattened. The abaxial surface is is rounded and is the parietal surface of the claw.

* Just distal to the metacarpophalangeal joint on the palmar aspect of the limb lie a pair of conical accessory claws. These are covered with horn and often contain dense connective tissue and small nodules of bone.
