Proximal Biceps Tenodesis
What is Proximal Biceps Tenodesis?
Proximal biceps tenodesis is the surgical reattachment of a torn proximal biceps tendon, which connects the upper part of your biceps muscle to the shoulder.
What causes a Proximal Biceps Tendon Tear?
- Causes for a proximal biceps tendon tear include:
- Falling on an outstretched arm
- Lifting very heavy objects
- Excessive use of the shoulder during sports and overhead activities
The risk factors for developing a proximal biceps tendon tear include:
- Use of certain medications
Symptoms of a Proximal Biceps Tendon Tear
You may experience one or more of the following symptoms:
- Sudden, sharp shoulder or upper arm pain
- Snapping sound or pop in the shoulder or upper arm region
- Tenderness at the shoulder
- Biceps muscle cramping
- The weakness with shoulder and elbow movements
- Difficulty rotating the forearm
Diagnosis of a Proximal Biceps Tendon Tear
Your doctor will look for specific signs such as the ‘Popeye Muscle’ sign where the biceps muscle bunches up near the elbow which implies a complete rupture of the proximal tendon. With partial ruptures, you feel pain while bending the arm. To confirm the diagnosis, your doctor may order an MRI or CT scan.
Why is Proximal Biceps Tenodesis Necessary?
Non-surgical treatment includes medication, resting or avoiding activities that aggravate your symptoms, application of cold packs or physical therapy. Proximal tendon tenodesis is recommended by your doctor if you:
- Do not respond to nonsurgical treatment methods
- Have other structures injured within the shoulder
- Are an active individual who requires restoration of muscle strength
How do You Prepare for Proximal Biceps Tenodesis?
You must avoid medications such as painkillers a few days before the surgery and will have to avoid eating or drinking for a couple of hours before surgery. Your doctor will give you specific instructions on how to prepare for the procedure.
How is Proximal Biceps Tenodesis Performed?
The surgery may be performed by arthroscopy (keyhole surgery) or open surgery if proximal bicep tenodesis is part of a larger surgery. Proximal bicep tenodesis may involve the following steps:
- You are given general anesthesia.
- A single 3.2 mm incision is made in the bone by Dr. Lee.
- An arthroscope, which is a thin tube-like instrument with a camera, is inserted through the incision to visualize the joint.
- The inside of the shoulder joint and the bicep tendon tear are displayed on a monitor.
- The injured tendon is detached from the shoulder joint (It may already be detached in the case of a complete tear).
- The frayed end of the long head of the bicep is clipped off.
- Dr. Lee uses an advanced technique where he uses a unicortical button to reattach the biceps tendon. He places the cortical button inside the bone and does not pass it through the bone, diminishing the risk for fracture.
- The incision is closed, and a surgical dressing is placed.
Risks Associated with Proximal Biceps Tenodesis
Proximal biceps tenodesis is a very safe procedure; however, there may be certain risks which include, but are not limited to, bleeding, infection, delayed healing, or failure to heal.
Recovery after Proximal Biceps Tenodesis
After the procedure, you may be given pain medicine for a few days to keep you comfortable and your shoulder will be supported by a sling for about a month. Physical therapy may be recommended after a week or two to maximize the range of motion and shoulder strength.
