Intended Use

MicroPort total hip systems are intended for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: 1. non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli. and painful hip dysplasia; 2. inflammatory degenerative joint disease such as rheumatoid arthritis; 3. correction of functional deformity; and, 4. revision procedures where other treatments or devices have failed.

Device Story

BIOLOX delta Option and Extra-long Heads are orthopedic implants consisting of femoral heads and neck sleeves used in total hip arthroplasty. Femoral heads are manufactured from alumina matrix composite; neck sleeves are manufactured from titanium alloy. The device functions as a modular component of a hip prosthesis system, connecting the femoral stem to the acetabular liner. It is used in clinical settings by orthopedic surgeons during hip replacement or revision surgery. The device provides a bearing surface and structural connection to restore hip function and relieve pain. The system is compatible with various previously cleared MicroPort femoral stems and acetabular shells. No software or AI algorithms are involved.

Clinical Evidence

No clinical data provided. Safety and effectiveness supported by bench testing, including static and post-fatigue burst strength, axial pull-off testing, rotational stability testing, and fretting corrosion evaluation.

Technological Characteristics

Femoral heads: alumina matrix composite; 28-44mm sizes; 16/18 or 12/14 conical bores. Neck sleeves: titanium alloy; short to extra-long sizes; 16/18 external taper, 12/14 internal taper. Modular implant system for total hip arthroplasty.

Indications for Use

Indicated for skeletally mature patients requiring total hip arthroplasty for non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli, painful hip dysplasia), inflammatory degenerative joint disease (rheumatoid arthritis), functional deformity correction, or revision procedures.

Regulatory Classification

Identification

A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.

Dear Allen Mamaril:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);

#### C. Substantial Equivalence Information

The design features and materials of the BIOLOX® delta Option and Extra-long Heads are substantially equivalent to those of the predicate devices cleared under K130376 and K072656. The indications of the subject devices are identical to the predicates. The fundamental scientific technology of the subject devices has not changed relative to the predicate devices. The safety and effectiveness of subject devices are adequately supported by the substantial equivalence information, materials information, and analysis data provided within this Premarket Notification.

# D. Nonclinical Testing

The subject BIOLOX® delta Option femoral heads were evaluated mechanically for static (or pre-fatigue) burst strength and post-fatigue burst strength.

The subject devices were evaluated for the stability of the taper system subjected to traction forces between the BIOLOX® delta Option femoral head and BIOLOX® delta Option neck sleeve by conducting an axial pull off test to measure distraction forces.

To the right of the square is the text "MicroPort" in blue, with "Orthopedics" underneath in red. Below the logo is the text "MicroPort Orthopedics Inc."

Rotational stability tests were also performed to measure the torque required to twist the BIOLOX® delta Option femoral head on the tapers.

Lastly, the subject devices were tested for fretting corrosion of the BIOLOX® delta Option sleeve and tapers of the stem/neck mating components.

# E. Clinical Testing

Clinical data was not provided for the subject devices.

# F. Biocompatibility

Biocompatibility information for the subject devices is included in the cited Master File. The intended patient contact, materials, colorants, manufacturing steps and processing additives used in the subject implant devices are identical to those of the predicate and reference devices. Therefore, additional biocompatibility testing was not completed on the subject devices.

The subject devices are implanted using existing specialized trial and impactor instruments, for which colorant and biocompatibility information were reviewed by FDA in K170444.
