Hemi Phalangeal Implant

Product catalog summary

Introduction
The document outlines the surgical technique for the Hemi Phalangeal Implant (HPI), designed to replace damaged articular cartilage at the base of the proximal phalanx of the hallux. The implant aims to maintain normal joint biomechanics and minimize friction with a highly polished Cobalt Chrome surface.

Specifications
The HPI features a thin, trapezoid shape with a rectangular stem base to prevent rotation. It includes a partial titanium coating for osseointegration and optional suture holes for tendon attachment. The implant is available in three sizes, with specific dimensions for head width and height.

Surgical Procedure
1. Make a longitudinal incision over the dorsomedial aspect of the First Metatarsal Phalangeal Joint.
2. Resect the base of the proximal phalanx perpendicularly.
3. Use the Sizer Instrument to select the appropriate implant size.
4. Ream the medullary canal and prepare it for the implant.
5. Place the Implant Trial Sizer to check fit and range of motion, then replace it with the HPI Implant.
6. Repair the joint capsule and close the wound.

Optional Suture Attachment
The implant includes suture holes for optional tendon reattachment, positioned on the medial and lateral plantar sides.

Recommendations
The document emphasizes that the surgical procedure is for informational purposes only, and surgeons must use their clinical judgment to determine the appropriateness of the device and techniques.

Hemi Phalangeal Implant SIZING AND ORDERING PART NO. The HPI stemmed prosthesis, with its very thin profile and trapezoid shape, is designed to replace the damaged articular cartilage of the base of the proximal phalanx of the hallux while maintaining normal biomechanics of the joint. The articular surface is a highly polished Cobalt Chrome surface to minimize friction and optimize range of motion with the metatarsal head. The anatomically engineered contour of the joint surface is enhanced with a recessed central plantar area to avoid irritation of the flexor tendons. A rectangular stem base...
