Question

1. list the eight types of fractures, describing the characteristics of each type.

a.
b.
c.
d.
e.
f.
g.
h.

1. identify each type of fracture illustrated below. refer to figure 10 - 11 in the textbook.
2. describe the initial and follow - up treatment of fractures.
3. describe why a bone may need to be replaced and the process for doing so.

Explanation:

a. Comminuted fracture: Bone breaks into three or more fragments.
b. Transverse fracture: Fracture line is perpendicular to the long - axis of the bone.
c. Oblique fracture: Fracture line is diagonal across the bone.
d. Compression fracture: Bone is crushed, often occurs in vertebrae.
e. Spiral fracture: Caused by a twisting force, fracture spirals around the bone.
f. Greenstick fracture: Incomplete fracture, one side of the bone is bent and the other side is broken, common in children.
g. Depressed fracture: Broken bone segment is pushed inward, often seen in skull fractures.
h. Impacted fracture: One end of the bone is forced into the adjacent bone segment.

For question 8, without seeing the actual figures clearly:
(A) - (H) would be identified based on the above - described characteristics.

For question 9, initial treatment of fractures usually includes immobilization (e.g., with a cast or splint) to prevent further movement and reduce pain, and may involve realigning the bone (reduction). Follow - up treatment may include X - rays to check healing progress, physical therapy to regain strength and mobility, and in some cases, surgical intervention if healing is not progressing well.

For question 10, a bone may need to be replaced if it is severely damaged (e.g., from a large tumor, severe trauma that cannot be repaired), has non - healing fractures, or has avascular necrosis. The process may involve using an allograft (donor bone), autograft (patient's own bone from another site), or a synthetic bone substitute. Surgery is performed to remove the damaged bone and implant the replacement, followed by a period of healing and rehabilitation.

Answer:

a. Comminuted fracture: Bone breaks into three or more fragments.
b. Transverse fracture: Fracture line perpendicular to bone's long - axis.
c. Oblique fracture: Diagonal fracture line across bone.
d. Compression fracture: Bone is crushed.
e. Spiral fracture: Caused by twisting, spirals around bone.
f. Greenstick fracture: Incomplete, one side bent, one side broken.
g. Depressed fracture: Bone segment pushed inward.
h. Impacted fracture: One end forced into adjacent segment.

1. (Answers depend on actual figures)
2. Initial: Immobilization, possible reduction. Follow - up: X - rays, physical therapy, possible surgery.
3. Need: Severe damage, non - healing, avascular necrosis. Process: Use allograft, autograft or synthetic substitute, surgery and rehabilitation.
