Project Description

Modular Thumb Implant

The BioPro Modular Thumb Implant is a two-piece implant consisting of a head and a press-fit plasma-sprayed stem designed to replace an arthritic carpometacarpal (CMC) joint.

Why offer your patients joint replacement?

If arthritis is localized to the carpometacarpal joint, implant arthroplasty may be a viable option.
The BioPro Modular Thumb Implant is a clinically proven joint replacement option, with 94% implant survivorship at 6-years.1 There is more to consider than simply implant survivorship though.

Research shows patients previously treated with both LRTI and joint replacement prefer their joint replacement and 97% of overall patients are satisfied with the procedure.1

Perhaps the most differentiating factor of joint replacement is sparing the trapezium, preserving multiple revision options if necessary in the future. There are numerous other benefits of the Modular Thumb Implant including:

  • Significant pain relief and improved function1,2
  • Faster recovery (on average 10 weeks faster than LRTI patients)1,2
  • Return of pinch and grip strength1,2
  • Maintains thumb length and cosmetic appearance1
  • Reduce operating time by ~19 minutes when compared to LRTI1

Implant Technology

The Modular Thumb Implant is a two-piece design, allowing each implant to be personalized to the patient’s anatomy. It offers 4 head diameters in 3 head offsets each, and 4 stem sizes. Utilizing modular components allow the head to be sized to match the anatomy of the trapezium and the stem to be sized to match the metacarpal. Additionally, head offsets allow the joint to be properly tensioned. This modular technology combined with our medial offset head and varus angle stem mimics natural joint anatomy. Data that highlights these features include:

  • Low revision rates1,2
  • Low subluxation rates1,2
  • No implant dislocations1,2
