An avulsion fracture at the base of the fifth metatarsal is sometimes called a "dancer's fracture" or a "pseudo Jones fracture", and usually responds readily to non-operative treatment. [18] The X-ray appearance of the developmental "apophysis" in this area may have some resemblance of a fracture, but is not a fracture; it is the secondary ...
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.
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 ...
Tailor's bunion, also known as digitus quintus varus or bunionette, is a condition caused as a result of inflammation of the fifth metatarsal bone at the base of the little toe. [1] It is usually characterized by inflammation, pain and redness of the little toe. Often a tailor's bunion is caused by a faulty mechanical structure of the foot.
Proximal fractures of 5th metatarsal. The tuberosity avulsion fracture (also known as pseudo-Jones fracture or dancer's fracture [2] is a common fracture of the fifth metatarsal (the bone on the outside edge of the foot extending to the little toe). [3] This fracture is likely caused by the lateral band of the plantar aponeurosis (tendon). [4]
The dorsal ligaments are strong, flat bands.. The first metatarsal is joined to the first cuneiform by a broad, thin band; the second has three, one from each cuneiform bone; the third has one from the third cuneiform; the fourth has one from the third cuneiform and one from the cuboid; and the fifth, one from the cuboid.
Base of 1st metatarsal and medial cuneiform: Superficial fibular nerve (L5, S1, S2) Everts foot and weakly plantarflexes ankle Fibularis brevis: Inferior two thirds of lateral surface of fibula: Dorsal surface of tuberosity on lateral side of base of 5th metatarsal
Its recommendations form the basis of radiological protection policy, regulations, guidelines and practice worldwide. The ICRP was effectively founded in 1928 at the second International Congress of Radiology in Stockholm, Sweden but was then called the International X-ray and Radium Protection Committee (IXRPC). [1]
