The thumb and large toe do not possess a middle phalanx. The distal phalanges are the bones at the tips of the fingers or toes. The proximal, intermediate, and distal phalanges articulate with one another through interphalangeal joints of hand and interphalangeal joints of the foot. [4]: 708–711 : 708–711
Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
The distal (tip) finger bones are divided into tuft (the very tip of the bone, at the end of each finger), shaft (the thinner middle section), and base. The rest of the finger bones (the middle finger bones, and the proximal or innermost finger bones) are divided into base, shaft, and condyle (outer end). Extensive tendons surround the joints ...

Early changes of acroosteolysis can be detected by x-ray. In this radiograph there is dissolution and fragmentation of the bone in several of the terminal phalanges.~CDC. Acroosteolysis is resorption of the distal bony phalanges. Acroosteolysis has two patterns of resorption in adults: diffuse and bandlike.
On each side of the interphalangeal joints of the fingers are diagonally placed fibrous bands. The proximal ends of the bands are near the dorsal phalanges of the hand and the distal ends of the bands are near the palmar margins of the digits. [citation needed]
In human anatomy, the radial (RCL) and ulnar (UCL) collateral ligaments of the metacarpophalangeal joints (MCP) of the hand are the primary stabilisers of the MCP joints. [1] A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx.
Origin: Medial epicondyle of the humerus (common flexor tendon) as well as parts of the radius and ulna: Insertion: Anterior margins on the base of the middle phalanges of the four fingers: Artery: Radial artery: Nerve: Median nerve: Actions: Flexor of fingers (primarily at proximal interphalangeal joints) Antagonist: Extensor digitorum muscle ...
