2 interrelated joints for the elbow

humeroulnar and radiohumeral

As elbow reaches full extension, the __________ _________ is received by __________ _____

olecranon process; olecranon fossa

With elbow in full flexion, __________ ________ fits into ________ _____

coronoid process; coronoid fossa

As elbow flexes 20 degrees or more, its bony ______ is unlocked, allowing for more side-to-side ______

stability; laxity

Stability in ______ is more dependent on the _______ (radial) collateral ligament & the _______ (ulnar) collateral ligament

flexion; lateral; medial

_____ collateral ligament is critical in providing _______ support to prevent elbow from _______ when stressed in physical activity

ulnar; medial; abducting

particularly crucial to high-velocity sporting activities requiring optimal medial elbow stability like baseball pitching

ulnar collateral ligament (UCL)

“Tommy John procedure” is conducted on what?

ulnar collateral ligament (UCL)

the “Tommy John procedure” is UCL surgical reconstruction using a tendon ______ such as ________ ______ tendon

graft; palmaris longus

_______ collateral ligament provides lateral stability & is rarely injured

radial

_______ ligament provides a sling effect around radial head for stability

annular

Elbow moves from _ degrees of extension to ___ to ___ degrees of flexion

0; 145; 150

In anatomical position, it is common for forearm to deviate laterally from arm 5 to 15 degrees

carrying angle

carrying angle is slightly greater in _________ limb than in __________ limb due to adaptive changes from ______ stress

dominant; nondominant; valgus
