SplintER Series: En Pointe

Dancer's FractureA 32-year-old female presents to the emergency department with right foot pain after rolling her ankle during dance class. On exam, there is mild swelling and tenderness over the 5th metatarsal. The above x-ray was obtained (Figure 1: Case courtesy of Dr. Henry Knipe, Radiopaedia.org, rID: 28104).  

 

The patient is diagnosed with a dancer’s fracture, a spiral or oblique fracture of the distal 5th metatarsal. 

  • Pearl: This fracture can occur even with a low energy mechanism of injury and is more commonly seen in the female population [1].

Patients may describe a mechanism where they roll over their foot or land after a jump. Often there is a reported “twisting” injury [2]. On exam, patients have swelling, tenderness, and sometimes ecchymosis over the 5th metatarsal shaft. 

  • Pearl: Be careful not to confuse this with a Jones fracture (proximal 5th metatarsal fracture) or a metatarsal stress injury, as management varies. 

A Dancer’s fracture is diagnosed with x-ray imaging (Figure 1). Most commonly, the fracture line extends from the lateral metatarsal distally and then travels medially at the more proximal end [1].

Dancer’s fractures are usually managed non-operatively [3]. In the ED, patients should be placed in a walking CAM boot or post-operative shoe. Patients can weight-bear as tolerated and can be discharged with sports medicine or orthopedic follow-up.

  • Pearl: These fractures take approximately 6-8 weeks to heal. In severely displaced or nonunion cases, surgery may be required [3].
