Fractures: Foot and Ankle
Ankle Fractures
Ankle fractures are one of the most common fractures seen in most emergency departments. They are usually related to patients slipping or twisting and rotating over there ankle. Damage can occur to the small bone on the outside (fibula) or the larger bone on the inside of the ankle (tibia) or to the ligaments which tie those bones together. Treatment depends on the stability of the ankle when it is weight-bearing, and can require x-rays, CAT scans or MRI scans. Treatment can range from fully weight bearing in a boot, to operations with plates and screws or rods. Dislocations of the ankle can happen at the same time that the bone breaks, and oftentimes this suggests a much worse injury with a more severe soft tissue stripping, and a chance of damage to the actual joint lining surfaces as well.
Heel fractures usually occur when people jump from a height and land awkwardly. The fractures can be displaced out of position or an displaced and treated on their merits oftentimes with non-weight bearing in a cast or boot for 6 to 12 weeks, or requiring operation to put the bones back into an anatomical position and hold them there with a plate and screws. Patients often develop stiffness after a calcaneal fracture, and can have pain for many years. Heel fractures are fortunately relatively uncommon, but may cause significant disability, such as stiffness, in the future.
Heel Fractures / Calcaneus Fractures
Midfoot fractures referred to the part of the foot between the toes and the ankle joint. They were first recognised in the Napoleonic wars by a surgeon called Lisfranc, who noticed them when soldiers fell from the horse and their foot caught in the stirrup in this area and the ligaments will bones were injured. These injuries need to be carefully assessed and often treated with plates or screws to realign them and prevent the arch of the foot collapsing and developing arthritis. These are severe injuries and can lead to long-term disability and pain. It is important that they are diagnosed and treated accurately.
Lisfranc (Midfoot) Fracture
Stress fractures of the foot are common particularly in military recruits who have normal bones but are subjected to walking long distances with heavy packs, thus overwhelming the bones ability to tolerate the forces being applied. These are called ‘March’ fractures as they are caused by marching. Stress fractures can also occur in relation to normal walking if people’s bones are. The intial treatment approach isy to reduce the amount of weight bearing done, and support this with either a boot or plaster for somewhere between six and 12 weeks. It is important to also look for any secondary causes such as osteoporosis. The majority of these fractures do not require anything further than non-operative treatment.
Stress Fractures of the Foot and Ankle
The talus is the ankle bone, which sits between the bottom of the shinbone (tibia) and the top of the heel bone (calcaneus). Talus fractures often occur from high energy injuries such as car accidents. The blood supply to the talus can be compromised when displacement of the bone can lead to tearing of the blood vessels, and ongoing damage to the bone from a lack of blood (osteonecrosis). The treatment is non-weight bearing for between six and 12 weeks, and anatomical realignment of the fracture which needs to be held with plates or screws or both. It is common for people to have long-standing stiffness after a fracture of the talus.

Toe fractures are common when people stub their toes. So long as the toe is not pointing sideways and will fit into a shoe, a non-operative pathway is recommended. It is uncommon to develop arthritis in the toes after a fracture. Forefoot fractures refers to the bones directly joining to the toes and these also also generally treated without surgery, depending on the severity and the number of bones broken. If one bone is broken, usually the bones on either side will help to hold it at length and splint it in the right position. Non-operative treatment usually requires treatment in a walking boot or in a cast.
