Device Story

BENCOX Delta Option Heads are prosthetic components for total or partial hip arthroplasty. Device consists of BIOLOX delta ceramic ball head and titanium alloy (Ti6Al4V) sleeve. Sleeve fits onto in-situ metallic hip stem taper; ceramic head fits onto sleeve. Used in orthopedic surgery to restore joint function in patients with degenerative joint disease or fractures. Surgeon-operated in clinical/OR setting. Provides mechanical articulation for hip joint. Benefits include pain relief and restored mobility. No software or electronic components.

Clinical Evidence

No clinical data. Substantial equivalence demonstrated via bench testing: burst testing, fatigue testing, post-fatigue burst testing, pull-off testing, torque-out testing, range of motion, and corrosion testing. Pyrogen/endotoxin testing performed per USP<161> and ANSI/AAMI ST72.

Technological Characteristics

Materials: BIOLOX delta ceramic (alumina composite per ISO 6474-2 Type X) and Ti6Al4V titanium alloy sleeve. Mechanical assembly: ceramic head on titanium sleeve on metallic hip stem taper. Non-electronic, mechanical prosthesis. Sterilization method not explicitly stated but compliant with sterility guidance.

Indications for Use

Indicated for patients requiring total or partial hip arthroplasty (primary or revision) due to non-inflammatory degenerative joint disease (e.g., avascular necrosis, osteoarthritis, traumatic arthritis), inflammatory degenerative joint disease (e.g., rheumatoid arthritis), non-union, femoral neck/trochanteric fractures of proximal femur, or failed previous surgery.

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 Yoorim Bae:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.
