    00:01 So now let's switch gears and talk about what happens when the bone is broken? So a fracture is a break in a bone.

    00:11 And there are actually many different types of fractures that can occur.

    00:16 We'll discuss the different fractures shortly.

    00:18 But for now let's talk about how we heal fractures? The healing process is going to involve three different phases that occur and approximately four steps.

    00:30 The first phase of healing of a bone fracture is going to be the reactive phase.

    00:36 So the bone has been broken.

    00:38 And now there's a space between the two pieces.

    00:42 During this process, the cellular debris is going to now need to be phagocytes hosts by immune cells.

    00:50 So this is going to elicit an inflammatory response.

    00:54 As well there's a recruitment of a lot of blood and other cells in order to clean up this area.

    01:01 This results in the formation of a blood hematoma between the two fragments of bone.

    01:10 During the reparative phase, we are now going to start forming a cartilaginous callus or cartilaginous band aid between the two pieces of bone.

    01:22 As well in this phase after we form the cartilage, we also start to replace that cartilage with bone tissue.

    01:31 This results in A. The formation of the fibrocartilaginous callus and B. The formation of the bony callus.

    01:40 After the formation of the bony callus, we finally get the remodeling phase.

    01:45 In this phase, we're just going to remodel the bone so that it takes on the original shape that the bone had before it was fractured.

    01:53 In some people, this remodelling is so well that you cannot even tell that there was a fracture in the first place.

    02:04 So as I said in the previous slide, we're going to discuss several different types of fractures.

    02:11 So the first type of fracture we're going to discuss is called an open fracture.

    02:16 This occurs when the breaking of the bone leads to the bone going through the skin and protruding out of the skin.

    02:24 This is in contrast to a close fracture, where the bone does not break the skin.

    02:31 In the second type of fracture, we have a comminuted fracture.

    02:36 In the comminuted fracture, the bone has been broken and it also results in small splinters or pieces of bone around the fracture as well.

    02:48 A third type of fracture, which exclusively occurs in children, as their bones are not completely calcified or hardened yet is the greenstick fracture.

    02:58 We call it the greenstick fracture because it resembles the green twigs.

    03:04 So when you break the green twig it might break on one end, but the other end does not completely break and instead it bends.

    03:12 So, again, this only occurs in small children whose bones are not completely developed yet.

    03:21 Another type of fracture is an impacted fracture.

    03:25 This is called this because it results from an impact of the bones.

    03:30 The two bones are going to snap together and push into each other.

    03:38 Another type of fracture is the Pott fracture.

    03:41 This fracture is specific for a fracture that occurs in the ankle of the body.

    03:50 And also we have the Colles fracture.

    03:54 Like the pott fracture, this one is specific for a certain part of the body.

    03:58 In this case, the wrist.

    About the Lecture

    The lecture Fractures and Bone Repair (Nursing) by Jasmine Clark is from the course Musculoskeletal System – Physiology (Nursing).

    Included Quiz Questions

    1. Reactive phase
    2. Proactive phase
    3. Restorative phase
    4. Reparative phase
    5. Bone remodeling phase
    1. The fracture causes splintered, crushed, or broken bone to break into pieces at the site of impact or between 2 main fragments.
    2. The fracture causes broken ends of the bone to protrude through the skin.
    3. The fracture results in only one side of the bone being broken while the other side is bent.
    4. One end of the fractured bone is forcefully driven into the end of the other.
