Dx: Jones fracture
Ankle and foot paint are common presenting complaints to the emergency department.  It is important to be able to tell the difference between a Jones fracture displayed above and a Pseudo-jones fracture.  Both of these fractures involve the base of the 5th metatarsal.
A Jones fracture goes through the diaphysis of the metatarsal just distal to the proximal tuberosity.  Treatment is immobilization, non-weight bearing, and orthopedic consult/prompt follow up.  This type of fracture is at a risk for non-union resulting in chronic pain.  In order to prevent these sequelae surgical fixation may be needed.
A Pseudo-jones fracture is an avulsion fracture of the proximal tuberosity of the 5th metatarsal.  It is also known as a dancer’s fracture.  It occurs at the insertion site of the peroneus brevis tendon and is caused by lateral ankle strain.  Patients should be discharged with a hard soled shoe and directed to weight bear as tolerated until symptoms improve.
