Intended Use

Aptis Medical Distal Radio Ulnar Head implant is intended for replacement of the distal radioulnar joint following ulnar head resection arthroplasty: Replacement of the distal ulnar head for rheumatoid, degenerative, or post-traumatic arthritis presenting with the following findings: Pain and weakness of the wrist joint not improved by non-operative treatment Instability of the ulnar head with radiographic evidence of dislocation or erosive changes of the distal radioulnar joint Failed ulnar head resection; eg. Darrach resection Primary replacement after fracture of the ulnar head or neck. Revision following failed ulnar head arthroplasty.

Device Story

Distal Radio-Ulnar Joint (DRUJ) implant; semi-constrained prosthesis for replacement of distal ulnar head. Surgical implantation into intramedullary canal of distal ulna; screw fixation to distal radius. Used by orthopedic surgeons in clinical/OR settings. Device restores joint function following resection arthroplasty, fracture, or failed prior arthroplasty; alleviates pain and instability; improves wrist joint mechanics.

Clinical Evidence

No clinical data provided; substantial equivalence based on design, material, and intended use comparison to predicate device.

Technological Characteristics

Semi-constrained prosthesis; materials: Cobalt-Chrome (Co-Cr), Ultra-High-Molecular-Weight Polyethylene (UHMWPE), Commercially Pure Titanium (CPTi). Fixation: intramedullary stem and screw fixation to distal radius. Single-use; surgical implant.

Indications for Use

Indicated for patients requiring distal radioulnar joint replacement following ulnar head resection arthroplasty due to rheumatoid, degenerative, or post-traumatic arthritis with wrist pain/weakness unresponsive to non-operative treatment, ulnar head instability with radiographic dislocation/erosive changes, failed prior ulnar head resection, primary fracture of ulnar head/neck, or revision of failed ulnar head arthroplasty.

Regulatory Classification

Identification

A wrist joint ulnar (hemi-wrist) polymer prosthesis is a mushroom-shaped device made of a medical grade silicone elastomer or ultra-high molecular weight polyethylene intended to be implanted into the intramedullary canal of the bone and held in place by a suture. Its purpose is to cover the resected end of the distal ulna to control bone overgrowth and to provide an articular surface for the radius and carpus.

Dear Mr. Babb:

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.
