Lundington's Sign
Purpose
editTo diagnose if the patient has a bicep tendon rupture.
Procedure
editThe patient may stand or sit directly in front of the examiner with his or her fingers interlocked and placed on their head. The examiner stands directly behind the patient and palpates the head of the biceps tendon on both arms while the subject contracts both arms at the same time. With the subject in front of the clinician, he or she contract both muscles while the examiner palpates both left and right biceps brachii muscles and more importantly palpating the tendon of the biceps.
Mechanism
editResults
editIf there is increased pain while contracting both muscles it is indicative of biceps brachii long head tendinitis. If the patient is unable to contract either bicep this could also mean there is a biceps rupture.
Adverse effects (or "Legal issues")

editNotes
editSpecial Considerations
editPatient must maintain stability in the humeral head during contraction. No tension maybe a cause of a biceps long head rupture.
