Lateral Elbow Pain: Local Tendinopathy or Cervical Referral?
A 47-year-old right-handed house painter reports 2 weeks of right lateral elbow and forearm pain that began after a weekend of rolling ceilings. Pain is 5/10 at rest and 8/10 with gripping. He has no neck pain, but cervical rotation to the right is limited to 50 degrees and reproduces a faint pull at the base of the neck. Lateral epicondyle tenderness is present; resisted wrist extension reproduces his forearm pain; resisted middle-finger extension is uncomfortable. Grip strength is 32 kg on the right and 41 kg on the left. He wants 'the elbow cracked back into place.' He has no history of trauma or fever.
1. Outline the examination sequence you would use to separate a local lateral elbow problem from cervical referral. What would you examine first, and why?

I would begin with a cervical and upper-quarter screen because the neck can refer pain to the lateral elbow, and missing a cervical or neurologic problem would make any local treatment misleading. The screen includes active and passive cervical range of motion, a neurologic examination (C5-T1 myotomes, dermatomes, reflexes), and provocative tests such as Spurling and cervical compression/distraction. I would then clear the shoulder, since rotator cuff and glenohumeral problems can refer distally.
Only after that would I focus on the elbow: palpation of the lateral epicondyle and common extensor origin, resisted wrist extension, resisted middle-finger extension, and grip dynamometry. The key comparison is whether his familiar lateral elbow pain is reproduced by local tests or by cervical provocation. In this case, the local tests reproduce the pain and the cervical rotation produces only a faint pull at the neck base, which points toward a local extensor tendinopathy. The examination sequence matters because the cervical finding should be interpreted in context, not in isolation.
2. How do you interpret the limited and mildly symptomatic cervical rotation? Does it establish a cervical cause?
Read the worked answer
It does not establish a cervical cause. Limited rotation to 50 degrees with a faint pull at the base of the neck is a nonspecific finding; it may reflect habitual guarding, mild degenerative change, or normal variation, and it reproduces a different pain than his presenting elbow pain. The provocative cervical tests are negative and the local elbow tests reproduce his familiar symptoms, so the cervical finding is more likely an incidental limitation than the source of his lateral elbow pain.
I would still document the cervical finding, recheck it at follow-up, and avoid overdiagnosing a cervical radiculopathy without neurologic findings. If he developed neck pain, paresthesia, weakness, or a positive Spurling test, I would revisit the cervical contribution. For now, the working diagnosis is lateral elbow tendinopathy, and treatment should target that while monitoring the neck.
3. He requests that you manipulate the elbow. What is your treatment decision, and what would you say in the consent discussion?
Read the worked answer
I would explain that manipulation is not 'cracking the elbow back into place'; there is no dislocation to reduce. I would offer a trial of conservative care directed at the extensor origin: activity modification, load management, grip and wrist-extensor eccentric exercise, manual therapy including soft-tissue work and mobilization, and possibly manipulation as an adjunct if it is comfortable and he understands the rationale. I would avoid manipulation if there is joint effusion, signs of infection, fracture, or inflammatory arthritis.
Consent discussion would include the working diagnosis, the alternatives, the expected time course (often weeks to months), and the risks: transient soreness, bruising, and rare injury. I would not promise a cure. I would also explain that the cervical restriction is being monitored but is not the primary target today. I would document the discussion, his agreement, and a plan to reassess pain and grip strength at 2 to 4 weeks.
