Elbow & Forearm - Therapeutic Exercise Review

This set of flashcards covers key anatomical structures, muscle actions, common conditions, and biomechanics related to the elbow and forearm as discussed in the lecture.

Humeroradial joint

A joint in the elbow formed between the humerus and the radius.

Proximal radio-ulnar joint

A joint that allows rotation of the radius around the ulna.

Medial collateral ligament

Ligament providing stability on the inner side of the elbow.

Radial collateral ligament

Ligament providing stability on the outer side of the elbow.

Brachialis

Muscle responsible for flexing the elbow.

Common flexor tendon

A tendon from the medial side of the elbow, from which several flexor muscles originate.

Common extensor tendon

A tendon from the lateral side of the elbow, from which several extensor muscles originate.

Valgus stability

Stability against force that pushes the elbow outward.

Varus stability

Stability against force that pushes the elbow inward.

Myositis ossificans

Bone formation in muscle tissue, often following injury.

Epicondylitis

Inflammation of the tendons at the elbow, can be medial (Golfer's Elbow) or lateral (Tennis Elbow).

Biceps rupture

Tear of the biceps tendon, often at the shoulder or elbow.

FOOSH injury

A fall on an outstretched hand, commonly leading to wrist or elbow injuries.

Humerus

The bone of the upper arm that articulates with the shoulder and elbow.

Ulna

The bone on the inner side of the forearm, opposite to the thumb.

Radius

The bone on the outer side of the forearm, thumb side.

Trochlea

A structure on the humerus that articulates with the ulna.

Capitulum

A structure on the humerus that articulates with the radius.

Brachioradialis

Muscle that flexes the elbow and assists with forearm rotation.

Pronator teres

Muscle that helps in pronating the forearm.

Triceps

Muscle responsible for elbow extension.

Anconeus

Small muscle assisting the triceps in extending the elbow.

Elbow flexion range of motion

Normal flexion is approximately 145-150 degrees.

Elbow extension range of motion

Normal extension is 0-5 degrees hyperextension.

Supination

Rotation of the forearm that turns the palm upwards.

Pronation

Rotation of the forearm that turns the palm downwards.

Tendinopathy

Degenerative condition of a tendon due to repetitive stress.

Lateral epicondylitis

Condition characterized by pain on the outer elbow due to overuse.

Medial epicondylitis

Condition characterized by pain on the inner elbow due to overuse.

Elbow dislocation

Injury where the bones of the elbow joint become misaligned.

Valgus stress

Force that causes the elbow to bend outward.

Muscle strength testing

Assessment of the muscle's ability to exert force.

Neurovascular disruption

Injury that affects both nerves and blood vessels.
