Diagnosis of distal biceps rupture:

Although ultrasound scans can contribute to the diagnosis, the best examination to confirm a tear of the distal biceps at the elbow is a bilateral and comparative clinical examination conducted by an experienced surgeon who will ascertain the absence of the tendon by palpating the elbow held in flexion and detect a sore spot at the middle third of the arm, corresponding to the tendon stump of the biceps, which is recoiled.

Definition of distal biceps rupture:

This surgical procedure is specialized surgery. The surgery is performed on an outpatient basis under regional anaesthesia, with the patient comfortably positioned in the supine. On this arthroscopic surgery photo the surgeon stands by the head of the patient. The Fluoroscan is at his feet.
Using the camera, the surgeon confirms that the tendon sheath is empty and direct avulsion of the bicipital tuberosity

Surgical treatment of distal biceps tear:

The first anchor is placed on the medial part of the radial tuberosity with the arm held fully supine, completely buried to prevent interference, then the surgeon places a second, more distal anchor.

The tendon is tied using a triple sliding suture, then the surgeon takes the biceps tendon down onto the tuberosity under endoscopic monitoring, confirming contact between the tendon and the bone is satisfactory and the suture solid.

This is the post-operative x-ray of the elbow and the cosmetic and functional result, with full mobility and a scar hidden in the flexion crease of the elbow. 

Recovery after surgery of distal biceps rupture

Elbow immobilization will be necessary for 6 weeks. Elbow rehabilitation will start 3 weeks after surgery, biceps strengthening after 2 months and matches after 3 months.
