The BioPro First MPJ Hemi Implant is the globally trusted solution for the treatment of hallux rigidus/limitus. Now in clinical use for over 65 years, the First MPJ Hemi Implant continues to demonstrate improved motion, long-term survivorship, and pain relief.
The BioPro® First MPJ Hemi Implant is only 2mm thick, requiring minimal bone resection at the base of the proximal phalanx for proper implantation. This feature is very important for two main reasons. First, this preserves the FHB (flexor hallucis brevis), which typically attaches 6-8mm from the base. Sacrificing the FHB can result in a lack of toe purchase post-operatively. Second, the minimal resection technique maintains bone stock within the joint. This is an extremely important point should revision surgery ever be required. Typical revision for an implant is a joint fusion. The minimal resection technique employed with the BioPro® First MPJ Hemi Implant leaves sufficient bone stock to accommodate a fusion, should the need arise in the future.
