🦾Assessing the Elbow — Clinical Tests and Red Flags

Elbow · The elbow's hinge-and-rotation design lets the forearm bend and turn simultaneously, but this dual role concentrates repetitive stress on a small set of tendons.

Quick answers

What is tennis elbow?

Tennis elbow, or lateral epicondylitis, is degenerative irritation of the tendons attaching to the outer bony bump of the elbow, most often related to repetitive wrist extension and gripping rather than tennis specifically.

What is golfer's elbow?

Golfer's elbow, or medial epicondylitis, is a similar condition affecting the tendons on the inner side of the elbow, associated with repetitive gripping and wrist flexion activities.

Is elbow tendinopathy an inflammatory condition?

Research has shown that chronically affected tendons often show degenerative changes with little active inflammation, which is part of why the term tendinopathy is now often preferred over the older term tendinitis.

How long does tennis elbow typically take to resolve?

Many cases improve substantially within six to twelve weeks with activity modification and progressive loading exercise, though some persist for six months or longer without proper management.

What is cubital tunnel syndrome?

Cubital tunnel syndrome involves compression of the ulnar nerve as it passes behind the inner elbow, producing numbness and tingling in the ring and little fingers.

Do elbow braces or straps help?

Counterforce bracing is commonly used to reduce load on irritated tendons during activity, though most guidelines consider it a supportive measure alongside, rather than a replacement for, progressive exercise.

Start with this section - Tests & assessment

Elbow assessment typically starts with a history of activity, grip demands, and symptom pattern, followed by palpation of the epicondyles and observation of active and passive range of motion.

Provocative tests that load the extensor or flexor tendons, along with nerve-specific tests, help confirm the likely source of symptoms among the joint, tendons, or nerve.

Assessment tests

Provoke lateral epicondylitis

Resisted wrist extension test

Resisting wrist extension with the elbow straight reproduces pain at the outer elbow in tennis elbow, helping confirm the tendon as the pain source.

Provoke medial epicondylitis

Resisted wrist flexion test

Resisting wrist flexion with the elbow straight reproduces pain at the inner elbow in golfer's elbow.

Detect ulnar nerve irritation

Tinel's sign at the elbow

Tapping over the ulnar nerve behind the inner elbow that reproduces tingling in the ring and little fingers suggests nerve irritation.

Assess cubital tunnel syndrome

Elbow flexion test

Holding the elbow fully bent for a period and noting whether it reproduces numbness or tingling helps support a diagnosis of ulnar nerve compression.

Assess ligament stability

Valgus stress test

Applying a gentle outward-bending stress to the elbow evaluates the integrity of the inner ligament, particularly relevant in throwing athletes.

Warning signs

These warrant prompt clinical review rather than unsupervised exercise progression.

Visible deformity after trauma

An obvious change in the elbow's shape following a fall or direct blow raises concern for fracture or dislocation and warrants urgent evaluation.

Inability to move the elbow after injury

A sudden loss of the ability to bend or straighten the elbow after trauma should be assessed promptly.

Rapidly spreading redness and warmth

Signs of spreading infection around a swollen elbow, especially with fever, require urgent medical attention.

Progressive hand weakness or muscle wasting

Worsening weakness or visible muscle loss in the hand can indicate significant nerve compression and warrants further evaluation.

This combination of history, palpation, and provocative testing generally allows clinicians to distinguish tendon, nerve, ligament, and joint sources of elbow pain without requiring imaging in most straightforward cases.
