I had a complete fracture of my left femur.,., and tomorrow will be my 4th month., and I'm still on my crutches., i can stand on my own., and 90% my my left leg is back,. but still i cant walk., my knee hurts., why?
You do not say how the fracture was treated, but in today's medical world, it is usually with an IM nail.
It usually take around 16 to 20 weeks for a femur fracture to unite. Some patients heal a little faster, some slower. But, this is just the time for the bone to heal.
This does not include the time for soft tissue rehabilitation. That can take up to 12 to 18 months.
You have to remember that you broke the largest bone in the body. It takes a lot of energy to do that. Not only the bone is injured. The periosteum is ripped off the bone, the muscles attachments are torn off, and the tendons, ligaments, fascia, nerves, blood vessels all get stretched and twisted while the thigh is not supported by an intact bone.
All of that soft tissue damage has to heal. Soft tissue heals with scar tissue. Scar tissue does not stretch or contract like regular tissues. It takes a while for the scar to mature, then it has to be rehabilitated.
At four months, you are just barely into the rehab phase. But, you are 90% back, that is really pretty good.
However, if you are having a lot of problems in the knee, you should have your orthopedic surgeon exam the knee. Occasionally, the knee is also injured in a femur fracture, but since the fracture is most important to treat right away, sometimes the knee injury gets overlooked till the patient start doing rehab.
Hang in there. You still have quite a ways to go. Have your surgeon take a look at your knee, the next time you see him/her.
I, too, have been concerned about femur pain. I had a bilateral femur fracture, my right one a compound. I Also broke my tight tibia. I was having lots of pain six months later and the Xray showed that one of the nails in my knee had broken. I can barely take a step when I go from sitting to standing and often have to use two canes. It has been ten months since my wreck. I just wonder if I will ever walk normally again. I'm very depressed about all I cant do. I had a car wreck and I'm 56
Sorry to hear about your injuries. But, with bilateral femur fractures (one open), along with a tibial fracture, you are lucky to be alive (bilateral femur fractuers still carry a fairly high mortality rate, at approximately 26%).
But, if you are continuing to have problems, you need a thorough evaluation. Usually, isolated interlocking screw breakage at the end of the IM nail does not cause any problems. The question is, why did the screw break?
Sometimes, the breaking of an interlocking screw signals that the frature has not completely healed (thus too much stress is applied to the hardware when the patient begins ambulation).
So, again, since you are continuing to have some problems, the fractures need reevaluation.
But, you do have to remember, it is not uncommon for just one femur fracture to take a young patient 18 to 24 months to fully recover from. You have three significant fractures to recover from, which is significant blow to the resources of the body.
Hang in there. At least you have a chance to get better (you are still alive). But, do see your surgeon.
