Other proximal fifth metatarsal fractures exist, although they are not as problematic as a Jones fracture. If the fracture enters the intermetatarsal joint , it is a Jones fracture. If, however, it enters the tarsometatarsal joint, then it is likely an avulsion fracture caused by pull from the fibularis brevis tendon.
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]
In runners, march fracture occurs most often in the metatarsal neck, while in dancers it occurs in the proximal shaft. In ballet dancers, fracture mostly occurs at the base of the second metatarsal and at Lisfranc joints. This fracture always occurs following a prolonged stress or weight bearing, and the history of direct trauma is very rare.
Proximal fractures of the fifth metatarsal are common, [2] and are distinguished by their locations: A proximal diaphysis fracture is typically a stress fracture, commonly among athletes. [3] [4] A metaphysis fracture is also called a Jones fracture. Due to poor blood supply in this area, such a fracture sometimes does not heal and surgery is ...
Jones fracture – a fracture of the proximal end of the fifth metatarsal; March fracture – a fracture of the distal third of one of the metatarsals occurring because of recurrent stress; Cuneiform fracture – a fracture of one of the three cuneiform bones typically due to direct blow, axial load, or avulsion [20]
The metatarsal bones or metatarsus (pl.: metatarsi) are a group of five long bones in the midfoot, located between the tarsal bones (which form the heel and the ankle) and the phalanges . Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe ): the first , second , third , fourth , and fifth ...
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.
Superior femoral neck stress fractures, if left untreated, can progress to become complete fractures with avascular necrosis, and should also be managed surgically. [13] Proximal metadiaphyseal fractures of the fifth metatarsal (middle of the outside edge of the foot) are also notorious for poor bone healing. [13]
