You can sit up after acetabular fracture surgery. When the people talk about the acetabular fracture cannot sit up, they mean that the acetabular fracture is not treated surgically, but by conservative treatment methods, playing traction and braking, so they cannot sit up. After sitting up, the acetabular fracture will cause some displacement. Acetabular fractures are generally recommended to be treated surgically, and it is possible to sit up after surgical treatment, and you can do some activities in bed. Acetabular fractures are generally not weight-bearing until 3 months after surgery. After surgery, you can use crutches and perform functional exercises without putting the affected limb on the ground and without weight-bearing. This is the time for acetabular fracture exercise. Patients who are treated conservatively must generally be bedridden for 2 months.
