Phalangeal joint arthrodesis implant

Phalangeal joint arthrodesis implants are small, non-bioabsorbable devices inserted directly into finger or toe joints (interphalangeal or phalangeal/metacarpal/metatarsal) to stabilize and fuse them. Clinically, they’re used to treat arthritis, joint deformities like hammer toe, or as a revision option for failed joint replacements, restoring function and reducing pain without requiring plates or screws.

These implants are typically metal-based and come in fixed-length designs, such as rods with barbs or X-shaped structures, but are not classified as intramedullary nails. Regulation varies by jurisdiction, and their supply—whether single-use or reusable—depends on the specific device’s design and manufacturer’s instructions, though none are intended for wrist, ankle, or foot arch joints.
