Intended Use

The indications for the Corin MetaFix Hip as a total hip arthroplasty, and when used in combination with a Corin hemi arthroplasty head, as a hip hemi-arthroplasty, include: • Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis • Rheumatoid arthritis • Correction of functional deformity • Treatment of non-union and femoral neck fractures • Developmental dysplasia of the hip (DDH) or congenital dysplasia of the hip (CDH) The MetaFix Hip is intended for cementless use only.

Device Story

The Corin MetaFix Hip Stem is a tapered femoral component for total or hemi-hip arthroplasty. It replaces damaged hip joint articulation to reduce pain and improve patient mobility. The device is implanted by orthopedic surgeons in a clinical setting. It is designed for cementless fixation, relying on sound bone for seating and support. The stem features a modular 12/14 taper for connection to femoral heads. The device is intended for patients with sufficient bone stock to support the prosthesis.

Clinical Evidence

No clinical testing was performed for this submission. Substantial equivalence is supported by the identical design and material characteristics to the predicate devices and a comparison of indications for use. Bacterial Endotoxin Testing (BET) was conducted on the finished product.

Technological Characteristics

Tapered femoral stem manufactured from titanium alloy (Ti6Al4V) with a hydroxyapatite (HA) coating. Available in various offsets (135° and 125°) and neck lengths. Designed for cementless fixation with a 12/14 modular taper for head attachment.

Indications for Use

Indicated for patients requiring total or hemi-hip arthroplasty due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, non-union, femoral neck fractures, or hip dysplasia (DDH/CDH). Intended for cementless use only.

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 Ms. King:

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.

# K162942

The Metafix hip is intended to provide increased patient mobility and reduce pain by replacing the damaged hip joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components.

The Corin MetaFix Hip Stem was originally cleared in K082525, K120362, K121439, K130634, K131952 and K153381. The purpose of this submission is to modify the labeling to remove an indications for use for the MetaFix Hip Stem, for clarity to ensure safe or effective use. The design and compatible components for use with the Corin MetaFix Hip stem subject of this submission are identical to that of the predicate device K082525, K120362, K121439, K130634, K131952 and K153381.

## 10. Intended Use / Indications:

The indications for the Corin MetaFix Hip arthroplasty, and when used in combination with a Corin hemi arthroplasty head, as a hip hemi-arthroplasty, include:

- Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis
- . Rheumatoid arthritis
- . Correction of functional deformity
- . Treatment of non-union and femoral neck fractures
- . Developmental dysplasia of the hip (DDH) or congenital dysplasia of the hip (CDH)

The Corin MetaFix Hip is intended for cementless use only.

# 11. Summary of Technologies / Substantial Equivalence:

The MetaFix Hip Stem subject of this submission is identical to the predicate MetaFix Hip Stem (K082525, K120362, K121439, K130634, K131952 and K153381) in design, materials, coating, sizes and similar in terms of intended use/indications for use. Based on these similarities, Corin believes that the MetaFix Hip Stem is substantially equivalent to the predicate device.

# 12. Non-Clinical Testing:

A comparison of indications for use and contraindications demonstrate substantial equivalence. Bacterial Endotoxin Testing (BET) has been conducted on finished product, using Limulus Amebocyte Lystate (LAL) kinetic chromogenic methodology.

# 13. Clinical Testing:

Clinical testing was not necessary in this Traditional 510(k).
