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.
