Project Description

BioPro® MPJ Hemi Implants

Successfully treating Hallux Rigidus since 1952.1

System Overview

The most comprehensive phalangeal based Hemi implant system available on the market today. BioPro Hemi Implants are simple to implant, remove the minimum amount of bone possible, and preserve the anatomy of the toe. The implants are an excellent alternative to arthrodesis, offering patients pain relief and motion.2

Patient Information

Clinical Benefits

Reproducible Results

The BioPro First MPJ Hemi Implant has over 70 years of clinical use with studies on average, reporting 95%+ implant survivorship.1-12 Simple instrumentation helps ensure consistent, reproducible results.

Satisfied Patients

Recent studies report 97% satisfaction at 8.3 years. In addition to maintaining motion, the implant allows for immediate weight bearing at the discretion of the surgeon allowing the patient to return to activity on average 5 weeks faster than fusion patients. 2

Revision Options

In the right patient, our implants have been proven to last 20+ years.3 If complications do arise, studies show conversion from a failed hallux phalangeal hemiarthroplasty to arthrodesis have similar success rates to primary arthrodesis.4
