Intended Use

Total and hemi-hip arthroplasty 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. Total or hemi-hip arthroplasty may be considered for younger patients if, in the opinion of the surgeon, an unequivocal indication for total or hemi-hip replacement outweighs the risks associated with the age of the patient and if limited demands regarding activity and hip joint loading can be assured. This includes severely crippled patients with multiple joint involvement for whom a gain in hip mobility may lead to an expectation of significant improvement in the quality of their lives.

Device Story

Summit Hip System consists of tapered femoral stems for total or hemi-hip arthroplasty. Stems are manufactured from titanium alloy (Ti-6Al-4V) or Cobalt-Chromium-Molybdenum. Porous-coated versions feature sintered commercially pure titanium beads (Porocoat), some with hydroxyapatite (HA) coating. Cemented versions use PMMA centralizers. Device is used by orthopedic surgeons in clinical settings to replace damaged hip joint articulation. System provides increased patient mobility and pain reduction. Output is a mechanical reconstruction of the hip joint. Clinical decision-making relies on surgeon assessment of bone quality and patient activity demands.

Clinical Evidence

No clinical data. Bench testing only, including hip head center analysis, corrosion analysis, range of motion analysis, and pyrogenicity testing.

Technological Characteristics

Materials: Titanium alloy (Ti-6Al-4V), Cobalt-Chromium-Molybdenum, commercially pure titanium bead porous coating (Porocoat), hydroxyapatite (HA) coating. Design: Tapered femoral stems, collarless or flanged/collared, various body sizes and offsets. Fixation: Cemented (with PMMA centralizers) or uncemented (press-fit).

Indications for Use

Indicated for patients requiring total or hemi-hip replacement due to osteoarthritis, rheumatoid arthritis, congenital hip dysplasia, avascular necrosis of the femoral head, acute traumatic fracture of the femoral head/neck, failed previous hip surgery, ankylosis, fracture dislocation, or non-union of femoral neck fractures. Hemi-hip replacement is also indicated for degenerative arthritis involving only the femoral head or pathology of the proximal femur treatable by hemi-arthroplasty. Specific stems are indicated for either cemented or uncemented use.

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.

| <b>SUBSTANTIAL EQUIVALENCE INFORMATION</b> | |
| The subject and predicate Summit stem devices are identical in design, materials, and coatings. Non-<br>clinical testing demonstrated performance equivalence between the subject and predicate devices. | |
| <b>SUMMARY OF NON-CLINICAL TESTS CONDUCTED FOR DETERMINATION OF<br/>SUBSTANTIAL EQUIVALENCE</b> | |
| To support a determination of substantial equivalence, non-clinical testing/evaluations were conducted. | |
| The following studies were provided:<br>● Hip Head Center Analysis – Demonstrated that Summit stem hemi-arthroplasty constructs do not<br>introduce new fatigue strength risks when compared to Summit stem total hip arthroplasty<br>constructs.<br>● Corrosion Analyses - Demonstrated that Summit stem hemi-arthroplasty constructs pose no<br>greater risk for corrosion when compared to the predicate device Summit and/or Actis stems.<br>● Range of Motion (ROM) Analysis – Concluded that the Summit stem hemi-arthroplasty<br>constructs have ROM equivalent to that of the predicate device Actis stem hemi-arthroplasty<br>constructs.<br>● Pyrogenicity Testing – Concluded that the subject devices meet the required endotoxin limits |…
