Intended Use

Indications commonly found in the interphalangeal joints; semi-rigid or rigid hammertoe deformity; angular deformity; impaired function and stability; pain; impaired toe length ratio. Implants are single use only.

Device Story

Stemmed flexible implant for replacement of lesser toe interphalangeal joints; constructed of medical grade silicone elastomer. System includes rods (2.0mm-2.5mm diameters), drills, and sizers. Used by surgeons in clinical settings to stabilize joints and correct deformities. Implant provides structural support to restore toe function and alignment; reduces pain. Single-use device.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and material similarity to predicate.

Technological Characteristics

Medical grade silicone elastomer; stemmed flexible rod design; diameters 2.0mm to 2.5mm; includes manual surgical instruments (drills, sizers).

Indications for Use

Indicated for patients with interphalangeal joint conditions including semi-rigid or rigid hammertoe deformity, angular deformity, impaired function/stability, pain, and impaired toe length ratio.

Regulatory Classification

Identification

A toe joint polymer constrained prosthesis is a device made of silicone elastomer or polyester reinforced silicone elastomer intended to be implanted to replace the first metatarsophalangeal (big toe) joint. This generic type of device consists of a single flexible across-the-joint component that prevents dislocation in more than one anatomic plane.

Summary:

This submission describes the OsteoMed Interphalangeal Flexible Stabilizing Rod System intended for indications commonly found in the interphalangeal joints; semi-rigid or rigid hammertoe deformity; anqular deformity; impaired function and stability; pain; impaired toe length ratio. OsteoMed Interphalangeal Flexible Stabilizing Rod Implants are intended for single use only.

The OsteoMed Interphalangeal Flexible Stabilizing Rod System is a stemmed flexible implant specifically designed for replacement of the interphalangeal joints of the lesser toes. It is constructed of medical grade silicone elastomer. The OsteoMed Interphalangeal Flexible Stabilizing Rods are offered in diameters of 2.0mm through 2.5mm. Drills and sizers will also be a part of the system.

Equivalence for this device is based on similarities in intended use, material, design and operational principle to the Sgarlato Laboratories Shaw-Ship Rod, Hammer Toe Implant.

Due to the similarity of materials and design to both pre-enactment and postenactment devices, OsteoMed believes that the OsteoMed Interphalangeal Flexible Stabilizing Rod System does not raise any new safety or effectiveness issues.

Dear Ms. Holdeman:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
