I had an ankle fracture/dislocation 10 years ago, and had surgery to reduce, fixed with a series of screws. my ankle is now frequenlty warm and itchy.?

Nickel allergy?: If you have a history of contact allergy to nickel which often causes a rash where jewelry touches your skin, you may have a similar kind of reaction to metal containing implants such as the screws and plates used for internal fixation of fractures. A patch test for nickel and/ or cobalt allergy can be done to help confirm this possibility.

Ankle arthritis: There are a number of issues that can playing a role from metal allergies (rare), to nerve damage, to ankle arthritis becoming more problematic.

Probably: Not related to previous surgery. If the ankle becomes painful see your orthopod..
