A 37-year-old male patient developed pseudoarthrosis after a closed fracture of the femur. Specify the type of regeneration in the patient:

Answer options

1. -
2. Reparative
3. Physiological
4. Pathological hypo-regeneration
5. Pathological hyper-regeneration

Explanation

In pseudo-arthrosis, the body perceives bone fragments as separate bones and does not attempt to unite them, so the bone would not regenerate. It will make sense to go with "Pathological hypo-regeneration".
