Metatarsal Fracture
Metatarsals are the long bones in the forefoot. There are five in each foot, one leading up to each toe and forming the metatarso-phalangeal (MTP) joints with the phalanges (toe bones) at the base of each toe.
What are the symptoms of an acute fracture?
- Acute pain at the point of trauma.
- Rapid swelling.
- Inability to weight bear.
- There may be deformity in the foot.
- Bruising will usually develop within 24 hours
Acute Metatarsal Fractures
Metatarsal fractures can be either an acute fracture or a stress fracture. They can be fractured through impact for example a vicious football stud (acute fracture), or through a more gradual onset, where repetitive impact causes a stress fracture.
This is a fracture to the metatarsal bone caused by some kind of violent impact. Often something is dropped on the foot or the foot might be stamped on. Alternatively, a violent twisting or turning motion at the ankle may cause a fracture in the 5th metatarsal in particular. These can include an avulsion fracture, where the tendon of the Peroneus Brevis muscle pulls a piece of the bone away. Or a Jones fracture which occurs at the base of the 5th metatarsal. This area typically has a poor blood supply and so healing may be affected.
Treatment
- See a Doctor as soon as possible.
- X-rays will be taken of the foot to confirm a fracture.
- If the bones are not displaced then a short cast or boot will be fitted for the first three weeks.
- After six weeks the foot should be X-rayed again to ensure it has healed.
- More complex or displaced fractures may require surgical fixation.
- Jones fractures require 6-8 weeks of non-weight bearing immobilisation.
- Once the cast has been removed, a thorough rehabilitation programme should begin to regain full mobility and strength.
- A gradual return to sport can then begin!
