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 ...

Blood vessels and nerves can also be affected by the pressure caused by any swelling in the leg.

The fifth metatarsal bone is a long bone in the foot, and is palpable along the distal outer edges of the feet. It is the second smallest of the five metatarsal bones. The fifth metatarsal is analogous to the fifth metacarpal bone in the hand. [1] As with the four other metatarsal bones it can be divided into three parts; a base, body and head.
A hand imitating an ulnar claw. The metacarpophalangeal joints of the 4th and 5th fingers are extended and the Interphalangeal joints of the same fingers are flexed.. An ulnar claw, also known as claw hand or Spinster’s Claw, is a deformity or an abnormal attitude of the hand that develops due to ulnar nerve damage causing paralysis of the lumbricals.
In the lower part of its course, it passes behind the sartorius muscle. Posteriorly: The artery lies on the psoas, which separates it from the hip joint, the pectineus, and the adductor longus. The femoral vein intervenes between the artery and the adductor longus. Medially: It is related to the femoral vein in the upper part of its course.
