[1] [2] Although generally associated with the fifth toe and big toe, it can occur in any toe. [1] [13] In such a fracture, the hard blow to the tip of the distal phalanx typically results in a transverse or oblique fracture in the proximal phalanx (base of toe), but can occur in any phalanx. [1] [13]
In the foot, the distal phalanges are flat on their dorsal surface. It is largest proximally and tapers to the distal end. The proximal part of the phalanx presents a broad base for articulation with the middle phalanx, and an expanded distal extremity for the support of the nail and end of the toe. [10]: 6b. 3.

The flexor hallucis longus and flexor digitorum longus flex the interphalangeal joint of the big toe and lateral four toes, respectively. The tendons of both of these muscles cross as they reach their distal attachments. In other words, the flexor hallucis longus arises laterally, while the flexor digitorum longus arises medially.
Colles' fracture – a distal fracture of the radius with dorsal (posterior) displacement of the wrist and hand; Smith's fracture – a distal fracture of the radius with volar (ventral) displacement of the wrist and hand; Barton's fracture – an intra-articular fracture of the distal radius with dislocation of the radiocarpal joint; Hand fracture
A Lisfranc injury, also known as Lisfranc fracture, is an injury of the foot in which one or more of the metatarsal bones are displaced from the tarsus. [1] [2]The injury is named after Jacques Lisfranc de St. Martin, a French surgeon and gynecologist who noticed this fracture pattern amongst cavalrymen in 1815, after the War of the Sixth Coalition.
They are analogous to the knuckles of the hand, and are consequently known as toe knuckles in common speech. They are condyloid joints , meaning that an elliptical or rounded surface (of the metatarsal bones) comes close to a shallow cavity (of the proximal phalanges).
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]
