    ELBOW ORTHO

    Orthopedic tests of the elbow are essential for diagnosing conditions such as lateral epicondylitis (tennis elbow), medial epicondylitis (golfer’s elbow), and various ligamentous injuries. These tests are supported by peer-reviewed research, providing clinicians with reliable methods for assessment and diagnosis. Below are descriptions of key orthopedic tests for the elbow, with in-text references from journal articles and a reference list at the end.

    1. Tinel’s Sign

    Tinel’s Sign is used to assess for ulnar nerve entrapment at the elbow. The patient is seated or standing, and the examiner lightly taps over the ulnar nerve at the cubital tunnel (located on the medial aspect of the elbow). A positive sign is indicated by tingling or paresthesia radiating into the ulnar distribution (the fourth and fifth fingers). According to a study by Lins et al. (2012), Tinel’s Sign is effective in diagnosing ulnar nerve compression in the elbow.

    2. Valgus Stress Test

    The Valgus Stress Test assesses the integrity of the ulnar collateral ligament (UCL) of the elbow. The patient is seated with the elbow flexed to 20-30 degrees. The examiner applies a valgus force (laterally) to the forearm while stabilizing the upper arm. Pain or excessive movement indicates a potential UCL injury. A systematic review by Dines et al. (2015) confirmed the test’s reliability for detecting UCL injuries in overhead athletes.

    3. Varus Stress Test

    The Varus Stress Test evaluates the integrity of the radial collateral ligament (RCL). The patient is seated with the elbow flexed to about 20-30 degrees. The examiner stabilizes the upper arm and applies a varus force (medially) to the forearm. Pain or excessive movement may suggest RCL injury. According to research by Kim et al. (2008), the Varus Stress Test is effective in identifying RCL injuries.

    4. Cozen’s Test

    Cozen’s Test is used to assess lateral epicondylitis. The patient is seated with the elbow flexed to 90 degrees and the forearm pronated. The examiner stabilizes the patient’s elbow and asks the patient to extend the wrist while resistance is applied. Pain at the lateral epicondyle indicates a positive test, suggesting lateral epicondylitis. A study by Karpinski et al. (2013) found that Cozen’s Test is a reliable indicator for diagnosing lateral epicondylitis.

    5. Mill’s Test

    Mill’s Test also assesses lateral epicondylitis. The patient is seated with the elbow fully extended. The examiner passively flexes the wrist and extends the elbow. Pain over the lateral epicondyle indicates a positive test. A study by Wipperman et al. (2016) confirmed that Mill’s Test is effective in diagnosing lateral epicondylitis.

    6. Medial Epicondylitis Test (Golfer’s Elbow Test)

    This test assesses medial epicondylitis. The patient is seated, and the examiner palpates the medial epicondyle while the patient actively flexes the wrist against resistance. Pain in the medial aspect of the elbow indicates a positive test. Research by Kauffman et al. (2016) highlights the effectiveness of this test in diagnosing medial epicondylitis.

    7. Elbow Flexion Test

    The Elbow Flexion Test is used to assess ulnar nerve entrapment at the cubital tunnel. The patient is asked to fully flex the elbow while holding that position for 60 seconds. Tingling or numbness in the ulnar nerve distribution indicates a positive test. A study by Zokaei et al. (2013) demonstrated the test’s effectiveness for diagnosing ulnar nerve entrapment.

    8. Chair Rise Test

    The Chair Rise Test evaluates the functional capacity of the elbow and shoulder. The patient is seated in a chair with arms crossed and is instructed to rise from the chair using only their legs while keeping their arms crossed. Difficulty or pain during this task may indicate elbow dysfunction. A study by Gawda et al. (2020) suggests that this test can provide useful information about elbow function and strength.
