My MRI just showed a peroneous brevis split tear. I'm an active 35 year old female, and I waterski competitively. The injury most likely occurred mid-July, when I broke my foot (lisfranc fracture that was surgically repaired with one screw, removed in September), so it's been a few months. I was on crutches for about 10 weeks, and obviously the tear did not heal. In fact, I had ankle pain when I flexed my ankle all along. Do I need surgery to fix this tear ? What's the prognosis with/without surgery ? Any info. helps.
