Can a hip fracture cause your leg to become shorter? if so is there anything that can done about it?

Yes it can: That being said, there are too many variables to know if anything can be done, including age of fracture and patient, where the fracture was at femoral neck verse shaft, type of fixation that was used if surgical fixation was necessary, etc. Normally, something can be done in the right patient. That being said, a shoe lift should be placed to avoid progressing arthritis in many different areas.

Possible: Femoral shortening is a well-known clinical finding after surgical treatment of per- and intertrochanteric fractures. Particularly, in geriatric patients with poor bone quality and unstable fracture types, secondary compression of these fractures often leads to length inequality of the lower limbs.
