definition

Besides the typical Scaphoid fracture on the wrist a fracture of the foot is also possible.
The Scaphoid bone of the foot is called in the technical language "Os naviculare" and is located between the talus and the sphenoid bones of the first two toes on the side of the big toe.

A Fracture of the scaphoid bone on the foot is rare, but especially less than one Scaphoid fracture of the hand. In case of fractures of the foot, in addition to the toes, mainly these are Ankle bone and the Heel bone affected, fractures of the small ones Tarsus are unusual.

causes

Fractions of the Scaphoid on the foot often arise through direct violence on the area of ​​the bone. It is often a matter of deliberate blows with blunt objects or accidents such as a forceful blow against a ledge.
Falling or unfortunate twisting and defending of the foot can also cause fractures in the smaller bones of the foot.

Since the navicular bone is a very small bone and offers hardly any surface for fractures to attack, the force of force must act specifically on the bone. It is not uncommon for the bones to be through Inflammation of the bones or osteoporosis pre-damaged, which causes instability of the bones.

Symptoms

It usually occurs immediately after the fracture local pain of the Inside of the foot. The foot can swell, become warm and hurt when touched and moved.
In addition, bruises can form, which causes the affected area around the navicular bone to turn visible red on the outside.

therapy

Treatment of a scaphoid fracture is usually given conservative. If the bones have not shifted against each other and do not restrict the movement of the foot, a plaster created. This immobilizes the foot for several weeks in everyday life to prevent the fracture from worsening and to ensure that it heals.
Physiotherapy can be used to encourage movement of the entire foot. However, the load on the navicular bone must be kept as low as possible.

If the break is postponed or the bone shattered, a surgery take place, in which the bone parts are put together in the right place and fixed to one another with wires.
Afterwards, a plaster cast must also be worn to immobilize the fracture so that the break heals in peace. Such operations are nowadays often minimally invasive as part of a Arthroscopy carried out.

Duration

Since the foot is loaded with the full body weight with every step, the bones are exposed to great pressure. It takes a long time for the scaphoid fracture to heal completely Immobilization respectively.
With a normal healing time you have to go with about 6-8 weeks calculate before the foot can be fully loaded again. After an operation, this healing time is often extended by two weeks.

In rare cases, excessive muscle wasting after the immobilization phase requires a protracted one Muscle building kick off. Osteoarthritis changes can also be chronic consequences of a broken bone (see: Pseudoarthrosis)
