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 metadiaphyseal fractures of the fifth metatarsal (middle of the outside edge of the foot) are also notorious for poor bone healing. [13] These stress fractures heal slowly with significant risk of refracture. [12]
Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
A Jones fracture is a broken bone in a specific part of the fifth metatarsal of the foot between the base and middle part [8] that is known for its high rate of delayed healing or nonunion. [4] It results in pain near the midportion of the foot on the outside. [ 2 ]
A stress fracture is an overuse injury that is caused by repetitive micro trauma exceeding the strength of a bone. Some stress fractures can heal with rest or immobilization.
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 ...
Freiberg disease, also known as a Freiberg infraction, is a form of avascular necrosis in the metatarsal bone of the foot. It generally develops in the second metatarsal, but can occur in any metatarsal. Physical stress causes multiple tiny fractures where the middle of the metatarsal meets the growth plate.
Examples of periosteal reactive bone in selected specimens of Triceratops. A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.
