Biomechanics
This type of shoulder instability is classic in throwers.
What is anterior instability?
This muscle group is the primary dynamic stabilizer to valgus stress in the elbow.
What is the flexor-pronator mass?
Osteophyte formation in the thrower's elbow will result in this deficit in motion.
What is extension deficit?
This term which rhymes with bird defines a rotational deficiency common in the thrower's shoulder
What is GIRD?
This study is the most sensitive for identifying MCL tears in the throwing athlete.
What is an arthrogram MRI scan of the elbow?
The transition from this phase of throwing to the next is where most shoulder injuries occur.
What is the late cocking to acceleration phase?
The single leg squat test can be used to identify this strength deficit in a throwing athlete.
What is hip abduction strength?
A partial tear of this tendon correlates with internal impingement.
What is the infraspinatus?
Also known as the O'Brien's test, this test is positive in SLAP tears.
What is the active compression test?
This specialized view on MRI scan is helpful for identification of labral tears in the thrower's shoulder.
What is the ABER view?
Peak shoulder angular velocity occurs in this phase of throwing.
What is deceleration?
This muscle is the first to contract when a pitcher initiates a throw.
What is the calf?
The MCL sees this type of stress during the acceleration phase of throwing.
What is tensile stress?
This test on the thrower's elbow will reproduce pain between 120° and 80° of elbow flexion.
What is the moving valgus stress test?
Osteochondral lesions are commonly seen in this area of the elbow in a throwing athlete.
What is the capitellum?
A tight posterior capsule shifts the glenohumeral rotation point in this direction.
What is posterior and superior?
Significant eccentric stress on the posterior rotator cuff occurs in this phase of throwing.
What is follow through?
This is the maximum daily pitch recommendation for an 8-year-old pitcher.
What is 50 pitches?
This test is performed by elevating the extended arm while an anteriorly-directed force is placed on the proximal humerus.
What is the dynamic labral shear test?
A kissing lesion on the posteromedial trochlea can be seen on MRI scan with this condition?
What is valgus extension overload?
The "C" in SICK scapula syndrome refers to this disorder.
What is coracoid pain?
Hypertrophy of this muscle can exacerbate ulnar neuritis in a thrower.
What is the medial triceps?
This bony adaptation of the proximal humerus can be seen in adolescent throwers.
What is humeral retroversion?
This two-step test performed with a neutral and a retracted scapula is used to assess the supraspinatus.
What is the Whipple test?
Also known as thrower's exostosis, this refers to the mineralization of the posterior band of the inferior glenohumeral ligament.
What is a Bennett lesion?
