BACKGROUND

Isolated radial head subluxation in an adult is not described in association with a distal biceps tendon rupture. In a PUBMED search, no articles were found with the above key words in combination. This patient had a biceps ten-don rupture and a radial head subluxation which was cor-rected without repair of the biceps tendon by strengthening the anconeus muscle and the lateral stabilisers of the radial head. Therefore this case report is unique for two reasons. This is the fi rst case reported of a radial head subluxation due to a biceps tendon rupture plus anconeus strengthen-ing exercises can be used as one of the treatment options. CASE PRESENTATION A 48-year-old gentleman presented to the accident and emergency department with a history of severe pain and a feeling of snapping of his left non-dominant arm accom-panied with a sense of giving way. This was when he lifted a heavy weight while at work. He ignored the pain at the fi rst instance as he did have a very high threshold of pain. Subsequently when he noticed that the ability to lift objects was week and he could not pronate and supi-nate the elbow as there was some restriction he decided to come to hospital. Findings that shed new light on the possible pathogenesis of a disease or an adverse effect Complete biceps tendon rupture resulting in radial head subluxation
