Do you know if you are having PLIF, ALIF, XLIF, 360 or whatever other initials might be out there? Will it be minimally invasive? Will have have hardware? Will they be using your own bone, or otherwise? All these answers play a part in your recovery, the length of your recovery, etc.
Very generally speaking, you can expect the first ten days to two weeks to be a bit rough. After you recover from the surgical pain, you will still have a great deal of healing to do. The bone does not fuse hard and strong for a year, even though some people show signs of fusion as early as about 3 weeks.
At the beginning you'll be restricted to walking, which is the most important activity you can do. Several short walks each day are better than one longer walk. Walking helps to stretch out the spinal nerves, helps the heart pump to supply freshly oxygenated blood to the surgical area, and it can help to keep developing scar tissue from attaching to a nerve.
People heal at different rates, so it is difficult to say how long it will take for one individual...but generally, surgeons' websites will say the patient will be off work anywhere from two to six months.
I had a PLIF at L4-5 three years ago this Jan. 8th and I had a 3 level fusion in June. One thing I've found is that you cannot rush the healing process along, and expect good results from your surgery. It is very important that you follow your surgeon's instructions, and avoid the usual activity restrictions (no bending at the waist, twisting, pushing, pulling or lifting anything heavier than a gallon of milk.) How long these restrictions are in effect is determined by your doctor's experience and how you are fusing. It is very important to develop patience because the fusing process takes longer than any of us would want....
Many people find it helpful to have someone with them for the first week or two. It is not absolutely necessary, but you will probably be on fairly heavy pain meRAB at the beginning. You will not be released from the hospital until you can take care of your bathrooms neeRAB, dress yourself and make it to your bedroom. If it is on the second floor, you will be clirabing stairs before they will release you.
I used to tell people that the most important items for me after surgery were a raised toilet seat and a satin bottom sheet. After my first fusion, I found it very difficult to reposition myself in bed. At the hospital I felt like I was stuck to the bed with velcro. The satin sheet makes it much easier to turn over, and shift from side to side. However, after my recent surgery, I had no trouble...and still can't figure out why.
There are many merabers who have had a fusion, if not several, so feel free to ask questions. Someone is bound to have an answer for you!!
I hope your anticipation of surgery will not spoil your holidays. In my case, I had heard so many horror stories prior to my first fusion that I was convinced it would be the most horrible event of my life. In reality, it wasn't all that bad. But it does take a long time to recover....If you know that going in, I think it makes the whole process a little easier!
Cheers!
