A patient experiences a nondisplaced fracture. what condition can potentially displace the fracture in the patient? crepitation ecchymosis muscle spasm edema and swelling

The answer is Muscle Spasm. Muscle spasm associated with low back pain or cervical whiplash, immobilize joint or part of body, and decrease a fracture or dislocation. It is a kind of irritation of tissues and protective response to injury and fracture; muscle spasm may displace a nondisplaced fracture or prevent it from reducing spontaneously.

I believe the answer is muscle spasm. Muscle spasm is a protective response to injury and fracture and an irritation of the tissues. It is also an involuntary contraction of the muscles. These spasms may prevent the fracture from reducing spontaneously or even displace a non-displaced fractured.
