Turning a small screw
This refers to techniques used in orthopedic surgery to assist in bone healing.
Which bones are involved in the healing process?
Right and left maxilla and palatine bones
These bones are part of the facial skeleton and can be affected by fractures.
What defines a complete fracture?
A fracture is complete if the bone breaks all the way through.
What distinguishes a displaced fracture from a non-displaced fracture?

Oblique Fracture.
What is a comminuted fracture?
A fracture where the bone breaks into several pieces.
What is a Boxer’s Fracture typically associated with?
Typically involves the fifth metacarpal from punching.
What forms at the fracture site during the initial healing phase?
Fracture Hematoma
This is a blood clot that forms to initiate the healing process.
What occurs during fibrocartilaginous callus formation?
New blood vessels grow, and cartilage is laid down.
What is the final step in the fracture repair process?
Bone Remodeling.
What condition causes bones to become brittle and prone to fractures?
Osteoporosis.
Who is most commonly affected by osteoporosis?
Common in older adults, especially post-menopausal women due to decreased estrogen.
What type of fractures can osteoporosis lead to?
Compression fractures, particularly in the vertebrae.
What can diagnose osteoporosis?
Bone density scans.
How is normal bone density indicated on scans?
Normal bone density is indicated in green.
How is osteoporosis shown on bone density scans?
Osteoporosis is shown in red.
What are traumatic fractures caused by?
Accidents or falls.
What causes stress fractures?
Due to repetitive activity.
What are pathological fractures a result of?
Underlying diseases like osteoporosis.
What is closed reduction?
Aligning bones without surgery.
What does open reduction involve?
Surgical intervention with pins or screws.
What are effective study tips for learning about bone fractures?
Use active learning techniques like flashcards and teaching others.
What should be included in a diet to maintain bone health?
A diet rich in calcium and vitamin D, and engage in weight-bearing exercises.
What does the phrase ‘break a leg’ imply?
