Long Bone Objectives Flashcards
What is the space between the diaphysis and epiphysis?
Metaphysis
What is the shaft, long part of the bone called?
Diaphysis
What is the wider part of the bone, more superior end—also known as ossification center?
Epiphysis
What is another name for the epiphyseal plate?
physeal line–are of growing tissues near the end of the long bone
Is the growth plat fused in a child?
No. It will show as cartilage
What is the anatomy of the elbow joint?
Joint is between the trochlear notch of the ulna and the trochlear notch of the radius and capitulum of the humeru.
involved in flexion and extesion
The joint between the head of the radius and the radial notch of ulna (proximal radioulnar joint) is responsible for what type of movement?
pronation and supination of forearm
What are the secondary ossification centers of the humerus?
“Come Hug My Tree of Life”
Capitellum Head of Radius Medial Epicondyle Trochlea Olecranon Lateral Epicondyle
How is nursemaid’s elbow fixed?
Reduction of the elbow by extending the radius and then “push it back into [lacce )supination and compression of the elbow joint.
What is the perilunate dislocation of the wrist?
dislocation of lunate into the carpal tunnel and disrupts the two main ligaments in the proximal row (scapholunate and lunotriquetral
What is the scaphoid fracture of the wrist?
This is usually from a fall and shows tenderness at the anatomic snuffbox
What is avascular necrosis of the scaphoid bone?
It has retrograde flow (all the blood is from proximal to distal).
Fractures at the proximal portion are less likely to heal because all vascularity is in the distal section of the bone.
What is the tip of the elbow called?
Proximal end (olecranon: tip of the elbow)
What is the membrane called between the ulnar and radial bones?
The interosseous membrane —which is where blood vessels penetrate
