What are the treatment options for distal biceps tendon rupture?

The distal biceps tendon connects the muscle to the forearm near the elbow and helps bend the elbow and turn the palm upward. A rupture can cause bruising, a change in muscle shape, pain, and reduced strength. The choice between observation and repair depends on the tear, arm demands, health factors, timing, and the strength a person needs to regain.

Until assessed, protect the arm from heavy lifting and forceful twisting. In selected people, non-operative care focuses on adapting activities and accepting some strength loss. If repair is recommended, [Tendon Repair Surgery](/treatments/reconstructive-orthopedic-surgery/tendon-repair-surgery/) reattaches the tendon to the forearm. [Post-Operative Rehabilitation](/treatments/physiotherapy-and-rehabilitation/post-operative-rehabilitation/) then progresses protection, movement, and strengthening according to the repair.

Arrange an orthopaedic assessment promptly after a sudden pop, bruising, a visible change near the elbow, or new difficulty turning the palm upward. Seek urgent care if the hand becomes cold, pale, numb, or severely swollen, or if the injury involved an open wound.

Is the tendon fully or partly torn? What strength and function might I retain without repair? If surgery is advised, how long will the arm be protected and when can rehabilitation begin?
