Milking test
Valgus stress test

19
Q

Little leaguers elbow risk factors

A

Number pitches thrown in the game, less than 25 pitches increased elbow injury to 21% 75 to 99 pitches increased risk to 35%

20
Q

Valgus extension overload syndrome definition, testing, and signs

A

Compression of the olecranon against humerus with a valgus stress generating a posterior medial impingement

Milking maneuver with elbow flexed to 90°

Flexion contracture, painful active extension with crepitus, passive range of motion painful and pronation valgus and extension
Tenderness to palpation at posteromedial olecranon

21
Q

Indications for ucl surgical intervention

A

Chronic instability, failure of nonoperative rehab, continued pain, sense of movement in elbow with valgus loads, inability to return to previous level of function

22
Q

Rehabilitation of UCL reconstruction

A

First one to two weeks range of motion restriction with hinged brace, strengthening introduced after 4 to 6 weeks, throwing not introduced until after four months, not allowed to return to sport until 9 to 12 months

23
Q

Risk factors for lateral tendinosis

A

35 to 50 years of age, female, high levels of physical work on a low social support at work, workers belonging to a profession classified as strenuous

24
Q

Special tests for medial and lateral tendinopathy

A

Medial – palpation of the medial epicondyles, grip strength, passive positioning test

Lateral – isometric contraction of wrist extension, grip strength, cozen test, mill test, three finger resistance test, handshake test

25
Q

Nonoperative management of elbow tendinopathy recommendations of evidence

A

Manual therapy – Mulligan mobilizations, cervical manual therapy
Exercise – eccentric, progressive exercises
Soft tissue mobilization- marginal evidence
Bracing/orthotics – short-term relief
Modalities – short-term relief
Corticosteroid injection- short-term relief
Low level laser – moderate benefit
Shockwave therapy- little or no benefit

26
Q

Special test for distal biceps tendon rupture

A

Hook test – SN/SP equals 1.0

Biceps crease interval test – SN = .92, SP = 1.0

27
Q

A

Cervical spine active range of motion limited in rotation towards involved side
Cervical spine distraction decrease in symptoms
Sperling’s test increase his symptoms

Four out of four = 90% possibility
Three out of four= 65%

28
Q

Cubital tunnel syndrome mechanisms of injury

A

Traction, long-standing valgus deformity, or strained postures of flexion contracture

29
Q

Patient education for nonoperative management of Cubital tunnel syndrome
