Talus fracture 1 yr ago, ankle still stiff w/ limited flexibility despite good stretching & freq rehab. pt say likely scar tissue. is that true/normal?

Possibly: Decreased range of motion can be contributed to either soft tissue obstruction/contracture or bony obstruction. A generalized rule is reduced range of motion throught, without crepitus, is attributed to soft tissue, abrupt end range limited motion is bony. Imaging studies such as x-rays, ct scans, and mris can help determine the underlying cause.

Not normal: It may be true that it is scar tissue but you should see a podiatrist for further evaluation.

Depends: On location of talus fracture. Fractures to the neck of the talus can create bone spurs which can impinge on the front of the ankle limiting ankle range of motion. Sometimes these spurs need to be cleaned out to restore full motion in the ankle joint.
