Hypernyms (scape is a kind of...): stalk; stem (a slender or elongated structure that supports a plant or fungus or a plant part or plant organ). Hyponyms (each of the following is a kind of scape): peduncle (stalk bearing an inflorescence or solitary flower).
How quickly you recover depends on how serious your shoulder injury is. Separated shoulders may heal over a period of 6 weeks. Dislocated shoulders may take longer -- more like 3 to 12 weeks. But these lengths of time are just approximations. Everyone heals at a different rate.
Whenever you develop force across an injured tissue, you're almost certainly retarding its healing. Some musculoskeletal injuries can take literally years to heal completely (I once injured my shoulder bench pressing and had to wait three years before I could bench press again without pain).
