At approximately 8 weeks, you will usually be able to remove the cast. This is both an exciting and anxious period. You will notice that the skin might be very dry and flaky, the joint will be stiff, and the area is swelled up and discolored. You can also see muscle atrophy due to the lack of movement over the past few weeks.
Don’t worry, this is completely normal! Keep in mind that during the immobilization period, your skin/muscles/tissues have not been stretched, your muscles have not contracted, the blood circulation has been reduced, so all these changes simply highlight the dis-use. However, this also signals the proper time to start using the injured body part again.
Although the bone fracture site has already healed in the immobilized position, the bone will require progressive stretches and exercises to be able to take on the loads from external forces required in your daily functioning. Don’t be surprised if the injured location will not be able to move much at the beginning. Due to the stiffness and muscle weakness, it is very common to also experience pain and swelling between 3-6 months post-fracture.
At this phase, your physiotherapist will help guide you on what you should be doing, what to avoid, and relearning how to move. The focus will first be on regaining full mobility at the joint which involves mobilizations, massage techniques, and stretches. Furthermore, we will start to gradually load the bone which helps to 1) activate the muscles 2) encourage bloody supply 3) get rid of swelling 4) improve bone healing.
It may take several weeks before regaining full mobility and returning to weight-bearing activities such as squatting/climbing stairs/walking (for lower-body injury) or pushing/plank/lying on the body part (for upper-body injury).
Week by week, you will notice an improvement in pain, mobility, and strength.
