The BioPro Modular Thumb Implant, for your patients that demand more.

The BioPro Modular Thumb Implant is the only two-piece hemiarthroplasty system specifically designed for CMC arthritis. With more than 20 years of clinical use and published 94% survivorship at six years, the system has become a trusted alternative to traditional trapeziectomy-based procedures.

Backed by 20 years of clinical use.

A review of 265 patients from three different published clinical studies.

  • No dislocations reported1,2,3

  • 88-94% implant survivorship1,2,3

  • 34.78-point QUICKDASH improvement2
  • Average VAS pain reduction from 8 to 13
  • Increased tip pinch improved from 10lbs to 14lbs1

  • Recovery on average 10 weeks faster than LRTI1

Improves strength and dexterity

The BioPro Modular Thumb Implant is engineered with a 15 degree ulnar angle and offset head, which mimics the natural alignment of the carpometacarpal joint. This not only prevents dislocation, but provides a stable construct for metacarpal leverage.

Maintains Thumb Height

Follow-up at an average of 6-years shows the BioPro Modular Thumb Implant preserved metacarpal length and cosmetics in all patients, with less than a 1% subsidence rate.1 This is achieved by minimal burring of the trapezium, only creating a shallow socket covering roughly 1/3 of the implant head. Additionally, by offering multiple head heights (0, +2mm and +4mm), the surgeon can achieve proper joint tension and alignment intraoperatively.

Faster Recovery

The recommended post-op protocol includes casting for 2-4 weeks, followed by 4 weeks of strengthening exercises with full recovery by 12 weeks. While many patients are virtually pain-free in a matter of weeks, clinical experience has shown that some patients may have discomfort for up to a year while the trapezium remodels. After remodeling, this discomfort typically resolves.

How it works

Metacarpal Resection

A precision cutting guide is engineered to remove 5-6mm of bone from the base of the metacarpal, parallel to the articular surface.

Socket Creation

Coarse and fine 12-15mm hemispherical burrs are utilized to create a shallow socket in the trapezium.

Metacarpal Broaching

Compression broaches matching the implant stem are inserted into the metacarpal to ensure a tight medullary interference fit.

Final Implant

After trialing, the final two piece implant is assembled and press-fit into the joint. Rapid mobilization is possible with average full recovery in 8-12 weeks.

Postoperative Remodeling

Following implantation, a predictable remodeling process occurs within the trapezium. During the first postoperative year, radiographs typically show gradual transformation of cancellous bone into a more sclerotic, dense structure as a result of physiologic loading.

This process leads to the formation of a congruent, stable socket that conforms to the implant head, creating a durable articulation surface and supporting long-term joint stability and function.

What patients are saying…

Patients are seeking alternatives to traditional procedures due to the long recovery times and limited revision options available. Our data proves that patients previously treated with an LRTI on their contralateral hand prefer the implant over the LRTI procedure.1 Listen to Ruth share her experience after receiving both an LRTI and a BioPro Modular Thumb Implant.

What surgeons are saying…

Leading surgeons are discovering the benefits of thumb joint replacement. The “burn no bridges” approach, allows surgeons to treat their patients earlier, with predictable results. Backed by 20 years of clinical experience, you can be confident you are treating your patients with a proven implant.

Tech Specifications

What’s Included

BioPro provides a reusable loaner instrument kit and (2) of each sterile packaged implants. Download the Bill Only Forms in the Document section for more ordering information.

Sizing

There are 48 total implant configurations. Head diameters of 12 mm, 13 mm, 14 mm, and 15 mm provide full trapezial coverage, each available with 0 mm, +2 mm, and +4 mm offsets to optimize joint tension. Four stem sizes—7.5 mm, 8.5 mm, 10 mm, and 11.5 mm—are offered, with +4 mm revision stems available for each size.

Material

The standard implant is manufactured from cobalt chrome, a highly biocompatible and durable material. A titanium version is available for use in patients susceptible to nickel chromium allergies.

Coating

The stem is coated with titanium plasma spray to improve biological fixation.
