Final answer:
The types of aseptic non-union are hypertrophic, atrophic, and oligotrophic. These types can occur due to factors like poor blood supply or infection. Treatment options may include surgery, bone grafting, or electrical stimulation.
Step-by-step explanation:
There are three types of aseptic non-union:
Hypertrophic non-union: This type occurs when there is excessive bone formation at the fracture site, leading to a bone that is larger than normal.
Atrophic non-union: In this type, there is inadequate bone formation at the fracture site, resulting in delayed or no healing.
Oligotrophic non-union: This type is characterized by minimal bone formation at the fracture site, leading to slow or incomplete healing.
These types of non-union can occur due to various factors, such as poor blood supply, infection, inadequate immobilization, or excessive motion at the fracture site. Treatment options for aseptic non-union may include surgery to stabilize the fracture, bone grafting, or the use of electrical stimulation to promote bone healing.
