He could use his intelligence to create some sort of gadget that helps him move around more easily while on crutches. Maybe a mini - jetpack that attaches to the crutches. In the fanfiction, this could lead to some funny moments when he first tries it out and things don't go as planned. Also, Flash Thompson could either make fun of him or, surprisingly, show some sympathy.
Peter might find it really difficult to swing around the city as Spider - Man while on crutches. So he could focus more on his school work and his relationships. For example, he could spend more time with Aunt May, helping her with cooking or just chatting. This would be a different side of Peter that we don't often see in the regular stories.
The fanfiction could explore how Peter's enemies react to him being on crutches. Some villains might think he's an easy target now. But Peter could use this to his advantage, pretending to be more vulnerable than he actually is. He could also meet a new character, perhaps a doctor who has some special knowledge about his powers and how to heal his injury faster while he's on crutches.
