Intended Use

The hip prostheses QUADRA-P and QUADRA-P collared are designed for cementless use in total or partial hip arthroplasty, for primary or revision surgery. The hip prosthesis QUADRA-P cemented is designed for cemented use in total or partial hip arthroplasty in primary or revision surgery. Hip replacement is indicated in the following cases: · Severely painful and/or disabled joint as a result of arthritis, rheumatoid polyarthritis or congenital hip dysplasia · Avascular necrosis of the femoral head · Acute traumatic fracture of the femoral head or neck · Failure of previous hip surgery: joint reconstruction, arthrodesis, partial hip arthroplasty, hip resurfacing replacement or total hip arthroplasty

Device Story

Quadra-P is a femoral stem implant for total or partial hip arthroplasty; part of Medacta Total Hip Prosthesis system. Cementless versions use titanium alloy (Ti6Al7Nb) with air plasma sprayed titanium and hydroxyapatite dual-layer coating; cemented versions use high nitrogen stainless steel. Features Eurocone (12/14) taper and polished neck. Used by orthopedic surgeons in clinical settings for primary or revision hip replacement. Provides structural support for femoral head replacement; integrates with modular femoral heads and acetabular components. Benefits patients by restoring joint function and reducing pain associated with arthritis, necrosis, or fracture. Subject of this submission is a size 00 range extension to existing Quadra-P line.

Clinical Evidence

No clinical studies were conducted. Substantial equivalence supported by bench testing including range of motion (ISO 21535), fatigue testing (ISO 7206-4/6), pull-off force testing (ASTM F2009), and coating characterization (ISO 13779-1, ASTM F1147).

Technological Characteristics

Femoral stems; cementless (Ti6Al7Nb alloy, ISO 5832-11) or cemented (High Nitrogen Stainless Steel). Cementless stems feature dual-layer coating (Titanium/Hydroxyapatite). Eurocone 12/14 taper. Sterilized. Mechanical performance validated per ISO and ASTM standards.

Indications for Use

Indicated for patients requiring total or partial hip arthroplasty (primary or revision) due to severely painful/disabled joints from arthrosis, traumatic arthritis, rheumatoid polyarthritis, congenital hip dysplasia, avascular necrosis of the femoral head, acute traumatic fracture of the femoral head/neck, or failure of previous hip surgeries.

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.

### VIII. Conclusion

Based on the above information, the Quadra-P implants new size 00 Standard version, is substantially equivalent to the identified predicate devices.

Substantial equivalence has been demonstrated through a comparison of intended use, design, and technological characteristics, as well as performance evaluations. The Quadra-P range extension implant is as safe and effective as the predicate devices, Quadra-P (K181254, Medacta International SA) and Quadra-P extension, (K192827, Medacta International SA)) (Only Cementless stems).
