Non-operative Proximal Biceps Rupture Treatment
When the proximal biceps tendon ruptures, the immediate treatment should consist of the application of ice to the upper arm, the use of an arm sling to support the arm and elbow, and the administration of an anti-inflammatory medication (if your medical history allows their use). The upper arm and shoulder may turn "black and blue".
The tenderness from the injury usually diminishes in seven to ten days and physical therapy can begin. The therapy would restore range of motion, strength and function. Rarely is there a loss of the strength of elbow flexion or of forearm supination after rehabilitation. Full recovery can be expected in six weeks.
