Introduction to Carmen and the Activity

Carmen is a fictional patient used for a practical exercise in fracture identification and treatment. The focus is on determining what actions to take regarding Carmen's fractures.

X-Rays Overview

  • X-Rays: High energy radiation used to view hard tissues like bones and teeth. X-rays penetrate soft tissues but are blocked by harder substances (bones).

  • Types of Imaging:

    • CAT Scans: Use radiation to produce images that include soft tissue details.

    • MRIs: Use magnets instead of radiation; not suitable for those with metal implants.

Fracture Identification Activity

Participants will examine X-rays using light tables. Utilize post-it notes to label fractures on X-rays:

  • Mark the fracture location with an arrow.

  • Identify the type of fracture using a fracture resource chart provided.

  • Emphasis on collaboration within groups to ensure all members participate in the activity.

Career Path Insights

  • Radiology Careers: Roles like X-ray technician can lead to specialized fields such as MRI or CAT scan technician. Educated at institutions like WCTC or MATC for certificates.

  • Earnings: Positions in radiology can yield salaries from $70,000 to $80,000 with a two-year degree. Doctors, particularly radiologists, may earn between $300,000 and $500,000 annually depending on their experience and specialization.

Project Activities

Overview of the project, which includes:

  • Modeling Fracture Patterns: Using chalk to simulate different types of fractures.

  • Types of Fractures: Bending, twisting, and impact fractures.

  • Anatomy of the Femur: Participants will label various parts of the femur.

  • Fracture Puzzles: Assemble models representing different fracture types and visualize break patterns.

  • Collaboration within partner groups is encouraged, but final work should be individual. Instructions and materials provided for conducting the activities successfully.

Important Reminders and Materials Needed

  • Materials: Light tables, X-ray sets, post-it notes, and chalk for model fractures. Reference for types of fractures available for identification practice.

  • Maintain attention to avoid mixing up materials between groups. Students encouraged to ask questions as needed to clarify tasks.

Bone Types

  • Long Bones: Longer than they are wide and support weight (e.g., femur, humerus). They consist of a shaft (diaphysis) and two ends (epiphyses).

  • Short Bones: Cube-shaped bones that provide stability and support while allowing for limited motion (e.g., carpals in the wrist, tarsals in the ankle).

  • Flat Bones: Thin and generally curved bones that protect internal organs and provide a surface for muscle attachment (e.g., skull, ribs, sternum).

  • Irregular Bones: Complex shapes that do not fit into other categories; they protect organs and allow for various movements (e.g., vertebrae, pelvic bones).

  • Sesamoid Bones: Small, round bones embedded in tendons that help absorb stress and improve the mechanical advantage of the joint (e.g., patella).

Wrap Up and Next Steps

Conclude activity with reflections on what was learned about fractures and imaging professions. Reminder about keeping all notes organized for final project submission, which is worth 30 points. Students will be allowed additional time tomorrow to continue working on assigned tasks and conclude the learning modules.
