The surgeon who did my 1st surgery said 10lb weight limit (gallon of milk weighs ~8.5lbs btw) and no driving for 4 weeks. The surgeon who did my 2nd surgery also said 10lb weight limit but no driving for 6 weeks. Age also plays a part in how fast a bone heals, so 4 weeks might be right for someone younger while it might be significantly longer for an older person. For reference I was 43 at the time of my first surgery and 50 at the time of my 2nd surgery. I agree with Tom that it takes longer than 4 weeks for FULL healing, as in back to pre-surgery strength.
