Common fracture in foot.
Usually spiral-oblique fracture
Interosseus, abductor, adductor and flexor muscles attach to base of proximal phalanx may cause displacement.
Immobilisation – felt and splintage to adjacent toes; silicone orthodigital device can be used to maintain immobilisation and alignment
Use a surgical/cast shoe
If displaced closed reduction under local anaesthesia – maybe use Kirschner wire fixation
