Unlikely SuspectPeroneus Tertius Tear in a Professional Ballet Dancer.

Peroneus tertius tendon tears are uncommon and patients typically recover with conservative management. The objec-tive of this case report is to highlight this usual injury and provide an alternative treatment option when conserva-tive management fails. A 24-year-old female professional ballet dancer presented with acute right lateral foot pain after hyperflexing over her pointe shoe. She completed a full course of physical therapy and non-steroidal anti-inflammatory drugs. However, upon returning to dance, she developed worsening pain and swelling over the lateral ankle. Magnetic resonance imaging revealed a complete peroneus tertius tear with retraction. She underwent surgi-cal debridement of this tendon and was able to return to dancing en pointe in 9 weeks.
