What makes BioPro Hemi Implants Different?

Our founder, Dr. Charles Townley, designed and first used his original implant in 1952. After forming BioPro, he obtained the rights to his design in 1991 and began promoting it as a BioPro implant.

Now 30 years later, we continue to develop the implant system and support surgeons who now have decades of experience with our implants and instrumentation. While the BioPro Implant has been replicated, our data, instrumentation, and implant variations continue to separate us from the rest.

Implant Options 

BioPro offers the most comprehensive phalangeal-based implant line.

Porous Coated

Beads placed on the backside of the implant help the bone grow into the implant, increasing implant stability.


Our patented HemiEDGE™ features an overlapping edge to help stabilize the implant, ensure proper placement and prevent bone overgrowth.

Lesser Implants

A variation of the implant is also available for the lesser metatarsal phalangeal joint in digits 2-5.

Multiple Sizes

Offering 5 sizes for the great toe and 9 sizes for the lesser toes ensures the best possible fit.

Mulitple Materials

Our standard implant is manufactured from Cobalt Chrome which has proven biocompatibility and durability, however, we also offer a titanium version for patients with a metal sensitivity.  Note, be sure to discuss this with your surgeon if you suspect you may have a metal sensitivity.


Our implants are similar in size to a US coin, allowing for minimal bone removal and maintenance of soft tissue attachments.

Resurfaces Phalanx

Resurfacing the proximal phalanx avoids the stresses on the metatarsal head, which can be as high as 119% of your bodyweight.
