A patient came in last week with an ankle injury from a sport I had never heard of called Spikeball (www.spikeball.com/ ). Popular among college students, Spikeball is a cross between volleyball and four square. Essentially people play the game around a circular trampoline-like net, which sits on the ground. Four players surround the net and “spike” the ball into the net. The pace is fast and furious and can result in unstable, single-leg landings, leading to severe sprains and strains, especially at the ankle.
