• Pain at the base of the thumb

• Difficulty gripping or pinching objects

• Swelling and tenderness near the joint

• Decreased strength

• Limited motion

• Aching pain after use or at night

Thumb arthritis affects millions of people and is particularly common in adults over 40.

Traditional surgical treatment often involves removing the trapezium bone at the base of the thumb (a procedure called trapeziectomy or LRTI). While effective for pain relief, this approach can sometimes lead to:

• Reduced grip or pinch strength

• Shortening of the thumb

• Longer recovery times

The BioPro Modular Thumb Implant offers a different approach.

Instead of removing the joint, the implant replaces it, allowing the thumb to maintain its natural structure and mechanics.

The BioPro system is a two-piece modular implant designed to restore movement and reduce pain in the thumb joint.

Key features include:

• Joint replacement rather than bone removal

• Modular sizing for a personalized fit

• Preservation of thumb length and natural appearance

• Improved grip and pinch strength

• Potential for faster recovery

• Future revision options if needed

The system offers multiple implant combinations, allowing surgeons to match the implant to a patient’s anatomy for optimal alignment and function.

You may be a candidate for the BioPro thumb implant if you:

• Have moderate to severe thumb arthritis

• Continue to experience pain despite splints, therapy, or injections

• Want to maintain thumb strength and motion

• Are seeking an alternative to trapeziectomy surgery

Dr. Zhang will evaluate your condition using imaging and a clinical examination to determine whether this procedure is the best option for your situation.

BioPro thumb joint replacement is typically an outpatient procedure, meaning patients go home the same day.

Typical recovery timeline:

Weeks 1–4

• Thumb immobilized in a cast or splint

Weeks 4–8

• Hand therapy begins to restore motion and strength

8–12 weeks

• Most patients return to unrestricted activities

Recovery varies depending on individual healing and therapy progress.

Studies examining patients who received the BioPro thumb implant have shown promising results.

Research has demonstrated:

• Significant reduction in pain scores after surgery

• Improved hand function and strength

• High patient satisfaction

In one clinical study, 10 out of 11 patients reported meaningful pain relief and functional improvement after surgery.
