The nine different types of fractures are as follows: 1. Stable Fractures: also known as a simple fracture, stable fractures occur when there is a clean break to the bone, but the severed parts remain in alignment. 2. Transverse Fractures: a transverse fracture occurs when the break line is at a straight, 90-degree line perpendicular to the shaft of the bone. 3. Comminuted Fractures: a comminuted fracture occurs when the bone splinters or breaks into more than two fragments. 4. Oblique Fractures: an oblique fracture occurs when the break is on an angle through the bone. 5. Compound Fractures: a compound fracture occurs when the broken bone pierces through the skin, leaving an open wound. 6. Hairline Fractures: also known as a stress fracture, hairline fractures are a small crack or severe bruise in the bone and usually occur on the feet as a result of repetitive movement, such as frequent jogging. 7. Avulsion Fractures: avulsion fractures occur when the break happens at the point where the bone attaches to the tendon or ligament. 8. Greenstick Fractures: commonly affecting children, greenstick fractures occur when only a portion of the bone is broken, and the unbroken part of the bone bends near the broken part. 9. Spiral Fractures: a spiral fracture occurs due to forceful rotation or twisting of a limb, causing a clean break into two different fragments.
