Metatarsal fractures range from very minor to severe injuries. It depends on the pattern of injury and the amount of displacement of the fracture. Metatarsal stress fractures were first described in 1855 and termed "march fractures" since they commonly occurred in military recruits.
Bone is composed of a network of collagen fibres impregnated with mineral salts (largely calcium phosphate and calcium carbonate), a combination that gives it great density and strength, comparable in some cases with that of reinforced concrete. Enclosed within this solid matrix are bone cells, blood vessels, and nerves. Bone gives our bodies support and structure, it protects our many vital organs and it acts as a reservoir for the important minerals we need every day. Let's say we start to work out at the gym.
Jones fracture : These metatarsal fracture sometimes take a longer time to heal. A stress fracture can be treated with a removable cast boot or cast worn for 6 to 8 weeks. Jones fractures are caused by overuse, repetitive stress, or trauma. They are less common and more difficult to treat than avulsion fractures, specially with fracture of the distal second metatarsal .
Fractures of the base of the fifth Metatarsal are the most common fifth Metatarsal injuries, and occur as a result of a twisting injury of the foot or ankle. The ankle rolls inward and there is a strong ligament that attaches to the base of the Metatarsal which pulls off a small bone fragment. Fractures in Zone I are typically avulsion type fractures, wherein a small fragment of bone is broken off the proximal end of the bone. Zone II fractures involve an area of the bone a little more distal (or toward the toes), and most typically appear as horizontal or transverse fractures. Fracture of the fifth metatarsal is the most common metatarsal injuries. This results from the twisting of the ankle.
