Avulsion fracture of the fifth metatarsal: experimental study of pathomechanics.
The commonly seen transverse fracture through the base of the fifth metatarsal is neither a Jones fracture nor an avulsion by the peroneus brevis tendon. This fracture was produced in cadaver feet, and it was demonstrated by computed tomography and dissection that the probable cause is avulsion by the lateral cord of the plantar aponeurosis.
