The patient may continue to ambulate without his walker. He is encouraged to do this so as to help with his fracture to heal.
Should a comma go in the second sentence also?
No, but the second sentence is incorrect.
It should be 'He is encouraged to do this to help his fracture to heal.'
If you must use 'so as to' it would be '...encouraged to do this so as to help the healing of his fracture.'
