First, it all depends on whether you have surgery to fix your femur fracture, known as an open reduction internal fixation procedure. If you do not require surgery, and you simply require a cast for a closed reduction, your physical therapy and your healing time will probably be shorter than if you had surgery.
Typical physical therapy and rehabilitation includes learning how to walk again after having your cast removed and any hardware that may be removed from the surgery. It involves normal and routine stretching exercises in addition to mobility and range of motion exercises. These are all designed to get your muscle strength back to normal.
Physical therapists often use different modalities including heat, ultrasound and range of motion and strengthening exercises.
Naturally, everybody's injuries affecting differently.
The femur is the largest human bone in our body. Being in a cast for 7 to 8 weeks is extremely debilitating and incapacitating.
It prohibits us from doing our daily activities. It often requires us to be on crutches, and after your cast been removed you may require the use of crutches, a cane or some other assistive device to help you get around until you are fully capable and comfortable bearing weight on that leg.
